STATEMENT AS TO SPONSORED RESEARCH

Funding for the work described herein was, at least in part, supported by grants from the National Institutes of Health (R01 GM058800; R21 ES012021-02).


BACKGROUND OF THE INVENTION

RNA-mediated gene silencing phenomena, known as post-transcriptional gene silencing in plants, quelling in fungi, and RNA interference (RNAi) in animals, are mediated by double-stranded RNA (dsRNA) and mechanistically intersect at the ribonuclease Dicer. Dicer is an RNase III-family enzyme characterized by its ribonuclease activity and dsRNA-binding properties. The enzyme generates nucleotide products from dsRNA of approximately 21-23. Processing of microRNAs, for example the let-7 precursor, by Dicer has also been observed. Dicer includes a dsRNA-binding domain located at the C-terminus of the enzyme.


Given the important role of Dicer in the generation of RNA-mediated gene silencing agents, the identification of proteins that interact with and/or regulate Dicer will help improve our understanding of RNA silencing and other Dicer-related processes. Moreover, Dicer-interacting and/or Dicer-regulating proteins are useful for the identification of a variety of modulatory agents for use in regulating RNA-mediated gene silencing.


SUMMARY OF THE INVENTION

Important in the RNAi pathway of most organisms is the ribonuclease III enzyme Dicer. In particular, Dicer has been shown to play a key role in the processing of RNA precursors triggering the activation of both endogenous and exogenous pathogen responses (i.e., RNAi) and of small RNAs active as developmental regulators called microRNAs. The enzyme and its ancillary components have been poorly characterized to date. The instant invention is based, at least in part, on the identification of numerous interacting components of the enzyme Dicer, in particular, proteins previously unknown to interact with this critical protein. Moreover, the invention provides an assay for the identification of other components of this and related enzymes. Importantly, the invention demonstrates that the identified interactors of Dicer are capable of modulating its function in, for example RNAi. Still further, the identified C. elegans proteins have related homologs in vertebrates, for example, the mouse and humans, and therefore have application in the development of human diagnostic and therapeutic agents.


Accordingly, the invention has several advantages, which include, but are not limited to, the following:


providing interacting proteins of Dicer and there use in modulating Dicer function;


methods for identifying further interactors of Dicer and their structural and functional characteristics;


method for regulating Dicer activity though the use of Dicer interactors;


methods for improving the in vitro or in vivo processing of Dicer proteins or for use as targets for pharmaceutical intervention in order to modulate the properties of Dicer in vivo for improved RNAi; and


methods for stabilizing RNAi agents/compositions comprising Dicer by the addition of stabilizing interactor proteins or the same for use in purifying Dicer and other Dicer components.


Other features and advantages of the invention will be apparent from the following detailed description and claims.




BRIEF DESCRIPTION OF THE DRAWINGS


FIG. 1 depicts a schematic of major components of the RNAi pathway, the role of Dicer, and Dicer interacting proteins, which have roles in microRNA maturation, RNAi initiation, and as enhancers of RNAi.


FIGS. 2A-C depicts biochemical fractionation and immunoprecipitations of DCR-1 from C. elegans embryos, and adults using the coupled HA monoclonal method. dcr−/− 8×HA rescue fractions and IP were realized using a complex array rescued strain of dcr-1 (ok247) with a transgene driving a 8×HA fusion.


FIGS. 3A-C depict the molecular architecture of the eri genes.


FIGS. 4A-B depict results regarding RNAi sensitivity, enhancement, and developmental defects of the eri genes. A. N2(WT) or eri mutants were fed on unc-73 (rnai) feeding strain for a generation and F1 broods of animals were scored for their exhibition of the associated phenotype: uncoordination, twisted morphology and limited movement (see lower panel). In the upper panel, results are shown for n=15, depicted error bars are shown for a confidence interval p=0.05. B. Brood sizes of the eri mutants at 15° C. (blue) and 25° C. (purple) are shown (upper panel). WT brood size is restored at 25° C. for all the eri mutations when crossing in with N2(wt) males (see lower panel). For all the broods, n=10, depicted error bars are shown for a confidence interval p=0.05.


FIGS. 5A-E depict small RNA defects in depletions for the DCR-1 interactors. In addition to dcr-1 and drh-3, the k02e2.6 locus also required the eri genes for accumulation, and the siRNAs were also absent from the eri genes RNA preparations from animals grown at 15° C. (5A-D). The lack of small RNAs in k02e2.6 in the eri mutants correlated with an upregulation of its mRNA, as quantified by real time PCR (5E). See the Materials and Methods for further detail.



FIG. 6 depicts a schematic showing that multiple silencing pathways are initiated by DCR-1, the eri gene products, and DRH-3. Distinct subsets of DCR-1 interactions are responsible for initiation of multiple small RNA silencing pathways. Shown here are the ‘classical’ RNAi pathway involving the RDE-1, RDE-4 and the DRH-1/2 proteins, the eri ‘endo’ RNAi pathway relying on the eri gene products, and the broader drh-3 dependent endo siRNA pathway.

I. Definitions


So that the invention may be more readily understood, certain terms are first defined.


As used herein, a “Dicer interacting protein” or “Dicer interactor” includes polypeptides having the amino acid sequences set forth in subsections IV, infra, as well as homologs, paralogs, and/or orthologs of such polypeptides, i.e. polypeptides having sufficient sequence identity to function in the same manner as the described polypeptides. Such polypeptides can interact directly, for example, physically bind with Dicer or a bioactive fragment thereof, and/or interact indirectly, for example, as measured by affecting a change in Dicer activity either in vitro or in vivo.


The term “Dicer” includes polypeptides having the amino acid sequences set forth in subsections III, infra, as well as homologs, paralogs, and/or orthologs of such polypeptides, i.e. polypeptides having sufficient sequence identity to function in the same manner as the described polypeptides.


The term “Dicer activity” includes any of the following properties or functions that can be ascribed to a Dicer protein such as: protein:protein binding activity (e.g., direct association with a Dicer interacting protein), miRNA maturation activity, RNAi initiation activity, RNAi enhancer activity, helicase activity, RISC activity, target recognition activity, and/or target gene cleavage activity.


The term “modulator of Dicer activity” includes agents capable of affecting a change in Dicer activity. Modulator agents include small molecules, nucleic acids (e.g., RNAi agents, siRNAs, shRNAs), peptides, and polypeptides. Dicer interacting proteins can be modulators of Dicer either directly or indirectly, for example, by physically interacting with Dicer or by affecting a change in Dicer activity. Thus, a modulator of a Dicer interacting protein which results in a change in Dicer activity can be considered a modulator of Dicer activity, albeit indirectly.


The term “derived from” includes partial, synthetic, recombinant, or genetically engineered nucleic acids or polypeptides that encode or represent a gene product substantially similar to a gene product from a particular source, for example, a nucleic acid source, a cell, or organismal source, from, for example, a nematode, fruit fly, rat, mouse, primate, or human.


The terms “homolog,” “paralog,” “ortholog,” includes their art recognized meaning. Typically, a homolog of a given gene product is one of functional similarity as well as sequence similarity. If the homolog is derived from a different organism, the homolog may be referred to as the ortholog. If several homologs exist in a given organism, the homolog may be referred to as a paralog. Typically, the sequence similarity/identity between homologs is at least about 40%, 50%, 60%, 70%, 80%, 90%, or more (or a percentage falling within any interval or range of the foregoing). Methods for determining such similarity/identity are described, infra. Motifs conserved between homologs can have a sequence similarity/identity of at least about 70%, 80%, 90%, or more. It is understood that when comparing gene product sequence between diverse organisms, for example, nematodes and humans, sequence similarity between given homologs across the entire protein sequence may be low. However, if functional complementarity exists, and in addition, if conserved motifs exist, e.g., protein; protein interaction motifs, e.g., motifs involved in Dicer activity or Dicer:Dicer interacting protein interactions, then the gene products being compared can be considered homologs and thus selected as compositions for use in the methods of the invention, as described herein.


The phrase “introducing into the cell or organism” includes any art recognized method for introducing genetic information into an cell extract, cell, or organism. Typical modes of such transfer of genetic information include the contacting, transfection, microinjection and/or feeding of nucleic acid agents or expression vectors to an extract, cell, or organism. Other methods include cell fusion, pronuclear injection, genetic crosses/mutagenesis, and the like.


The term “bioactive fragment” includes any portion (e.g., a segment of contiguous amino acids) of a Dicer interactor or Dicer protein sufficient to exhibit or exert at least one Dicer protein- or Dicer-associated activity including, for example, the ability to bind to Dicer or Dicer interactor protein, respectively.


The phrase “encodes a gene product” includes the generation of a RNA molecule from a DNA molecule (i.e., a complementary RNA molecule generated from the DNA molecule by the process of transcription) and/or the generation of a polypeptide or protein molecule from an RNA (i.e., by the processes of transcription and translation).


The term “kit” is any manufacture (e.g. a package or container) comprising at least one reagent or component, e.g. a construct, molecule, and/or compound, the manufacture being promoted, distributed, or sold as a unit for performing the methods of the invention.


The term “target gene” includes a gene intended for downregulation via RNA interference (“RNAi”). The term “target gene product” or “target protein” refers to a gene product, e.g., a nucleic acid or protein, intended for downregulation via RNAi. The term “target RNA” refers to an RNA molecule intended for degradation by RNAi, e.g., by nucleic acid cleavage. An exemplary “target RNA” is a coding RNA molecule (e.g., an RNA molecule encoding a gene product, e.g., an mRNA and protein so encoded therefrom).


The term “expression” of a gene or nucleic acid encompasses not only cellular gene expression, but also the transcription and translation of nucleic acid(s) in cloning systems and in any other context.


The term “RNA interference” or “RNAi”, as used herein, refers generally to a sequence-specific or selective process by which a target molecule (e.g., a target gene, protein, or RNA) is downregulated. In specific embodiments, the process of “RNA interference” or “RNAi” features degradation of RNA molecules, e.g., RNA molecules within a cell, the degradation being triggered by an RNAi agent. Degradation is catalyzed by an enzymatic, RNA-induced silencing complex (RISC). RNAi occurs in cells naturally to remove foreign RNAs (e.g., viral RNAs). Natural RNAi proceeds via fragments cleaved from free dsRNA which direct the degradative mechanism to other similar RNA sequences. Alternatively, RNAi can be initiated by the hand of man, for example, to silence the expression of target genes.


The term “RNAi agent”, includes an RNA (or analog thereof), comprising a sequence having sufficient complementarity to a target RNA (i.e., the RNA being degraded) to direct RNAi. A sequence having a “sufficiently complementary to a target RNA sequence to direct RNAi” means that the RNAi agent has a sequence sufficient to trigger the destruction of the target RNA by the RNAI machinery (e.g., the RISC complex) or process. The term RNA agent or RNAi agent includes small interfering RNA (siRNA) (also referred to in the art as short interfering RNAs) as well as small hairpin RNA or shRNA.


The term “small interfering RNA,” “siRNA,” or “short interfering RNAs” includes a double-stranded RNA agent, which is capable of directing or mediating RNA interference. Naturally occurring siRNAs are generated from longer dsRNA molecules (e.g., >25 nucleotides in length) by a cell's RNAi machinery (e.g., the RISC complex).


The term “small hairpin RNA” or “shRNA” (also referred to in the art as “short hairpin RNA”), includes an RNA agent having a stem-loop structure, comprising a first and second region of complementary sequence, the degree of complementarity and orientation of the regions being sufficient such that base pairing occurs between the regions, the first and second regions being joined by a loop region, the loop resulting from a lack of base pairing between nucleotides (or nucleotide analogs) within the loop region.


The term “subject”, as used herein, includes living organisms at risk for or having a cellular, neurological, e.g. neurodegenerative disease, or disorder. Examples of subjects include humans, monkeys, cows, sheep, goats, dogs, cats, mice, rats, and transgenic species thereof. Administration of the compositions of the present invention to a subject to be treated can be carried out using known procedures, at dosages and for periods of time effective to modulate RNAi in the subject as further described herein.


The term “treatment”, as used herein, is defined as the application or administration of a therapeutic agent to a subject, or application or administration of a therapeutic agent to an isolated tissue or cell line from a subject, who has a disease or disorder, a symptom of a disease or disorder, or a predisposition toward a disease or disorder, with the purpose to cure, heal, alleviate, relieve, alter, remedy, ameliorate, improve or affect the disease or disorder, the symptoms of the disease or disorder, or the predisposition toward a disease or disorder. A therapeutic agent includes, but is not limited to, small molecules, peptides, antibodies, ribozymes, antisense oligonucleotides, RNAi agents, chemotherapeutic agents, and radiation.


The term “effective amount”, as used here in, is defined as that amount necessary or sufficient to treat or prevent a disorder, e.g. a neurological or a neurodegenerative disease or disorder. The effective amount can vary depending on such factors as the size and weight of the subject, the type of illness, or the particular agent being administered. One of ordinary skill in the art would be able to study the aforementioned factors and make the determination regarding the effective amount of the agent without undue experimentation.


The term “pharmaceutical composition” as used herein, refers to an agent formulated with one or more compatible solid or liquid filler diluents or encapsulating substances, which are suitable for administration to a human or lower animal.


The phrase “a gene involved” in a disorder includes a gene, the normal or aberrant expression or function of which effects or causes a disease or disorder or at least one symptom of said disease or disorder.


The phrase “examining the function of a gene in a cell or organism” refers to examining or studying the expression, activity, function, or phenotype arising therefrom.


A “suitable control” or “appropriate control” refers to any control or standard familiar to one of ordinary skill in the art useful for comparison purposes. In one embodiment, a “suitable control” or “appropriate control” is a value, level, feature, characteristic, property, etc. determined prior to performing an RNAi methodology, as described herein. For example, a Dicer activity, a RISC level of activity or amount, target gene level or target gene degradation level, a transcription rate, mRNA level, translation rate, protein level, biological activity, cellular characteristic or property, genotype, phenotype, etc. can be determined prior to introducing a nucleic acid or test compound of the invention into a cell extract, cell, or organism.


The term “cell” refers to any eukaryotic cell which exhibits RNAi activity and includes, e.g., animal cells (e.g., mammalian cells, e.g., human or murine cells), nematode cells, plant cells, and yeast. The term includes cell lines, e.g., mammalian cell lines such as HeLa cells as well as embryonic cells, e.g., embryonic stem cells and collections of cells in the form of, e.g., a tissue.


The term “cell extract” refers to a lysate or acellular preparation of a cell as defined above and can be a crude extract or partially purified as well as comprise additional agents such as recombinant polypeptides, nucleic acids, and/or buffers or stabilizers.


The term “organism” refers to multicellular organisms such as, e.g., C. elegans, Drosophila, mouse, and human.


The term “vector” refers to a nucleic acid molecule (either DNA or RNA) capable of conferring the expression of a gene product when introduced into a host cell or host cell extract. In one embodiment, the vector allows for temporal or conditional expression of one or more nucleic acids of the invention, e.g., a single strand, RNA agent, siRNA, or shRNA. The vector may be episomal or chromosomally (e.g., transgenically) integrated into a host cell genome.


The terms used herein are not intended to be limiting of the invention.


II. Overview


Dicer, a ribonuclease III/DExH-box helicase (DCR-1 in C. elegans) plays a central role in a variety of small RNA-directed gene silencing mechanisms for a large range of organisms (see FIGS. 1 & 6).


Its best characterized activity is the processing of double-stranded RNAs into smaller RNA hybrid species of 21 to 25 nucleotides (nt) in length with staggered 2 nucleotides overhangs at the 3′ ends of the duplex, and a 5′ phosphate group; both of which determinants have been shown to be required for efficient silencing.


This Dicer activity was first shown to act in the initiation phase of two modes of post-transcriptional gene silencing. In RNA interference (RNAi) and in the microRNA-dependent silencing, Dicer recognizes a double-stranded RNA (dsRNA) trigger to direct a potent, and sequence-specific gene silencing response. This process requires the assembly of the small RNA product in a downstream complex called RISC, for which Argonaute proteins are a central component. This complex is responsible for a cognate mRNA search, and for the subsequent silencing of the complementary transcript.


Dicer is responsible for the integration of a variety of RNA signals with distinct biological outcomes. Dicer also initiates other RNA-dependent silencing pathways such as chromosome folding and the like. Therefore a key problem to address is how some specific classes of dsRNAs are recognized and recruited to be processed by Dicer, and how RNA triggers of distinct origins potentiate different silencing responses.


The present invention provides methods and compositions for conducting in vitro and in vivo assays for identifying Dicer interacting proteins, in particular, Dicer interacting proteins that can affect Dicer activity, and modulators thereof.


III. Dicer Interacting Proteins or Dicer Interactors


According to the invention, several proteins have been identified as interacting with and/or regulating Dicer, e.g., Dicer activity. These Dicer interactors are described in detail below under subsections IIIA through IIIMM. Using methods described in the present disclosure, use of any one of these proteins, or cognate orthologs or paralogs, in appropriate screening assays would provide for the identification of Dicer modulators and/or RNAi-modulators, and/or gene silencing modulators.

IIIB. ALG-1


ALG-1 is a homolog of rde-1 that is involved in RNA interference and affects developmental timing along with alg-2 and dcr-1 by regulating expression of the lin-4 and let-7 small temporal RNAs. The ALG-1 protein contains regions of similarity to Pfam domains PF02170 (PAZ domain, Residues 377-514), PF02171 (Piwi domain, Residues 660-961). The protein has been implicated in embryonic development, inferred from mutant phenotype Grishok, A. et al., Cell 2001 106:23-34. Homologs include H. sapiens eukaryotic translation initiation factor 2C 4, C. elegans gene T07D3.7a, M. musculus Argonaute 1 protein (Fragment), R. norvegicus eukaryotic translation initiation factor 2C 2 (eIF2C 2) (eIF-2C 2)s(Golgi ER protein 95 kDa) (GERp95) and D. melanogaster AGO1.

On Jan. 24, 2003 thissequence version replaced gi: 11545922.Summary: DEAD box proteins, character-ized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNAhelicases. They are implicated in anumber of cellular processes involvingalteration of RNA secondary structuresuch as translation initiation, nu-clear and mitochondrial splicing, andribosome and spliceosome assembly.Based on their distribution patterns,some members of this family are be-lieved to be involved in embryogenesis,spermatogenesis, and cellular growthand division. This gene encodes a DEADbox protein that is upregulated in re-sponse to treatment with beta-inter-feron (IFNB) and a protein kinase C-activating compound, mezerein (MEZ).Irreversible reprogramming of melanomascan be achieved by treatment with boththese agents; treatment with eitheragent alone only achieves reversibledifferentiation.FEATURESLocation/Qualifierssource1 . . . 1025/organism = “Homo sapiens”/db_xrefr = “taxon: 9606/chromosome = “2”/map = “2p24.3-q24.3”Protein1 . . . 1025/product = “melanoma differentiationassociated protein-5”/note = “DEAD/H (Asp-Glu-Ala-Asp/His)box polypeptide”CDS1 . . . 1025/gene = “IFIH1”/coded_by = “NM_022168.2:223 . . . 3300”/db_xref = “CCDS: CCD52217.1/db_xref = “GeneID: 64135/db_xref = “MIM: 606951ORIGIN  1msngystden fryliscfra rvkmyiqvepvldyltflpa evkeqiqrtv atsgnmqave 61lllstlekgv whlgwtrefv ealrrtgsplaarymnpelt dlpspsfena hdeylqllnl 121lqptlvdkll vrdvldkcme eelltiedrnriaaaenngn esgvrellkr ivqkenwfsa 181flnvlrqtgn nelvqeltgs dcsesnaeienlsqvdgpqv eeqllsttvq pnlekevwgm 241ennssessfa dssvvsesdt slaegsvscldeslghnsnm gsdsgtmgsd sdeenvaara 301spepelqlrp yqmevaqpal egkniiiclptgsgktrvav yiakdhldkk kkasepqkvi 361vlvnkvllve qlfrkefqpf lkkwyrviglsgdtqlkisf pevvkscdii istaqilens 421linlengeda gvqlsdfsli iidechhtnkeavynnimrh ylmqklknnr lkkenkpvip 481lpqilgltas pgvggatkqa kaeehilklcanldaftikt vkenldqlkn qiqepckkfa 541iadatredpf keklleimtr iqtycgmspmsdfgtqpyeq waiqmekkaa kegnrkervc 601aehlrkynea lqindtirmi daythletfyneekdkkfav ieddsdeggd deycdgdede 661ddlkkplkld etdrflmtlf fennkmlkrlaenpeyenek ltklrntime qytrteesar 721giiftktrqs ayalsqwite nekfaevgvkahhligaghs sefkpmtqne qkeviskfrt 781gkinlliatt vaeegldike cniviryglvtneiamvqar graradesty vlvahsgsgv 841iehetvndfr ekmmykaihc vqnmkpeeyahkilelqmqs imekkmktkr niakhyknnp 901slitflcknc svlacsgedi hviekmhhvnmtpefkelyi vrenkalqkk cadyqingei 961ickcgqawgt mmvhkgldlp clkirnfvvvfknnstkkqy kkwvelpitf pnldyseccl1021fsded//

The referencesequence was derived from BC012146.1and BC008492.1.Summary: Ribosomes, the organelles thatcatalyze protein synthesis, consist ofa small 40S subunit and a large 60Ssubunit. Together these subunits arecomposed of 4 RNA species and approxi-mately 80 structurally distinct pro-teins. This gene encodes a ribosomalprotein that is a component of the 60Ssubunit. The protein belongs to the L3Pfamily of ribosomal proteins. It islocated in the cytoplasm. The proteincan bind to the HIV-1 TAR mRNA, and ithas been suggested that the proteincontributes to tat-mediated trans-activation. This gene is co-transcribedwith the small nucleolar RNA genes U43,U86, U83a, and U83b, which are locatedin its first, third, fifth, and seventhintrons, respectively. As is typicalfor genes encoding ribosomal proteins,there are multiple processed pseudo-genes of this gene dispersed throughthe genome.FEATURESLocation/Qualifierssource1 . . . 403/organism = “Homo sapiens”/db_xref = “taxon: 9606/chromosome = “22”/map = “22q13”Protein1 . . . 403/product = “ribosomal protein L3”/note = “60S ribosomal protein L3;HIV-1 TAR RNA-binding protein B“CDS1 . . . 403/gene = “RPL3“/coded_by = “NM_000967.2:27 . . . 1238”/db_xref = “CCDS: CCDS13988.1/db_xref = “GeneID: 6122/db_xref = “MIM: 604163ORIGIN 1mshrkfsapr hgslgflprk rssrhrgkvksfpkddpskp vhltaflgyk agmthivrev 61drpgskvnkk evveavtive tppmvvvgivgyvetprglr tfktvfaehi sdeckrrfyk121nwhkskkkaf tkyckkwqde dgkkqlekdfssmkkycqvi rviahtgmrl lplrqkkahl181meiqvnggtv aekldwarer leqqvpvnqvfgqdemidvi gvtkgkgykg vtsrwhtkkl241prkthrglrk vacigawhpa rvafsvaragqkgyhhrtei nkkiykigqg ylikdgklik301nnastdydls dksinplggf vhygevtndfvmlkgcvvgt kkrvltlrks llvqtkrral361ekidlkfidt tskfghgrfq tmeekkafmgplkkdriake ega//

It encodes a DiCer Re-lated. From Pfam homology, the productwould have ATP binding, nucleic acidbinding, ATP dependent helicase, heli-case, RNA binding, double-stranded RNAbinding, ribonuclease III activities,would be involved in RNA processingand would localize in intracellular.According to the Worm TranscriptomeProject, it is expressed at high levelat all stages of development [KoharacDNAs], except dauers [SAGE]. Itsexistence, but not its exact sequence,derived here from the genome sequenc-ing consortium annotation, is sup-ported by 26 cDNA clones.Phenotype[WormBase] dcr-1 is required both forRNA interference and for synthesis ofsmall developmental RNAs. Fertilizationof dcr-1 oocytes does not occur. Whilethis fertilization defect can be res-cued by a dcr-1(+) transgene, fertil-ized eggs fail to hatch, and mothersare defective in egg-laying. Whereaswild-type oocytes normally do not un-dergo cell division in the gonad, dcr-1 (pk1531) oocytes undergo such divi-sion frequently. dcr-1 mutations alsocause postembryonic defects: alae areabsent in 60%, and a burst vulva isobserved in 80%, of dcr-1 (pk1531)homozygotes. The postembryonic defectsare consistent with the hypothesis thatdcr-1 mutants hyperactivate lin-41 invivo because they are unable to formactive let-7 stRNA; in vitro assays ofDCR-1 protein confirm that it can gen-erate let-7 stRNA from a double-stranded let-7 precursor.

V. Screening Assays


According to the invention, the following assays may be used to identify compounds that modulate interaction (e.g., binding) of Dicer or bioactive fragments thereof with Dicer interactors or bioactive fragments thereof, or modulate a Dicer activity or Dicer interactor activity, and hence, modulators of gene silencing or RNAi. Such modulators are particularly useful in regulation of (1) processing of miRNA precursors; (2) processing of siRNA precursors; (3) mediating mRNA cleavage; (4) mediating assembly of RISC (e.g., via siRNAs); (5) directing translation repression (e.g., via miRNAs); (6) a ribonuclease activity (e.g., cleavage of dsRNA); and (7) initiation of RNAi. The assays feature identifying modulators of the activity of Dicer interactors or bioactive fragments thereof, including, but not limited to, those activities identified in supra.


The assays of the present invention are used to identify modulators of the activity of Dicer or bioactive fragments thereof or Dicer interactors or bioactive fragments thereof. The modulators of the present invention are particularly useful in modulating Dicer and/or RNAi related activities but can also affect non-RNAi related activities.


VA. Cell Free Assays


In one embodiment, an assay of the present invention is a cell-free assay in which a composition comprising assay reagents (e.g., a Dicer interactor polypeptide, Dicer polypeptide or biologically active portions thereof), is contacted with a test compound and the ability of the test compound to modulate binding of the Dicer interactor polypeptide to the Dicer polypeptide (or bioactive fragments thereof) is determined. Binding of the Dicer interactor or Dicer (or bioactive fragments thereof) can be accomplished, for example, by coupling the polypeptide or fragment with a radioisotope or enzymatic label such that binding of polypeptide reagents can be determined by detecting the labeled compound or polypeptide in a complex. For example, test compounds or polypeptides can be labeled with 125I, 35S, 33P, 32P, 14C, or 3H, either directly or indirectly, and the radioisotope detected by direct counting of radioemmission or by scintillation counting. Alternatively, polypeptides can be enzymatically labeled with, for example, horseradish peroxidase, alkaline phosphatase, or luciferase, and the enzymatic label detected by determination of conversion of an appropriate protein to product.


Determination of binding of reagents can also be accomplished using a technology such as real-time Biomolecular Interaction Analysis (BIA). Sjolander, S. and Urbaniczky, C. (1991) Anal. Chem. 63:2338-2345 and Szabo et al. (1995) Curr. Opin. Struct. Biol. 5:699-705. As used herein, “BIA” is a technology for studying biospecific interactions in real time, without labeling any of the interactants (e.g., BIAcore™). Changes in the optical phenomenon of surface plasmon resonance (SPR) can be used as an indication of real-time reactions between biological molecules.


In a preferred embodiment, the assay includes contacting Dicer polypeptide or biologically active portion thereof with a Dicer target molecule, e.g., a Dicer interactor or a bioactive fragment thereof to form an assay mixture, contacting the assay mixture with a test compound, and determining the ability of the test compound to interact with the Dicer polypeptide, wherein determining the ability of the test compound to interact with the Dicer polypeptide comprises determining the ability of the test compound to preferentially bind to Dicer or the bioactive portion thereof as compared to the Dicer target molecule (e.g., a Dicer protein). In another embodiment, the assay includes contacting the Dicer interactor polypeptide or biologically active portion thereof with a Dicer interactor target molecule, e.g., Dicer or a bioactive fragment thereof to form an assay mixture, contacting the assay mixture with a test compound, and determining the ability of the test compound to modulate binding between the Dicer interactor polypeptide and the Dicer polypeptide.


In another embodiment, the assay is a cell-free assay in which a composition comprising a Dicer polypeptide and a Dicer interactor polypeptide (or bioactive portions thereof) is contacted with a test compound and the ability of the test compound to modulate (e.g., stimulate or inhibit) the activity of the Dicer polypeptide or Dicer interactor polypeptide (or biologically active portions thereof) is determined.


Determining the ability of the test compound to modulate the activity of a Dicer or a Dicer interactor polypeptide can be accomplished, for example, by determining the ability of the Dicer interactor polypeptide to modulate the activity of a downstream binding partner or target molecule by one of the methods described herein for cell or organism-based assays. For example, the catalytic/enzymatic activity of the target molecule on an appropriate downstream protein can be determined as previously described.


In yet another embodiment, the cell-free assay involves contacting a Dicer interactor polypeptide or biologically active portion thereof with a Dicer interactor target molecule that binds the Dicer interactor polypeptide to form an assay mixture, contacting the assay mixture with a test compound, and determining the ability of the test compound (e.g., Dicer) to preferentially modulate the activity of a Dicer interactor binding partner or target molecule, as compared to the Dicer protein.


In more than one embodiment of the above assay methods of the present invention, it may be desirable to immobilize either the Dicer interactor or Dicer (or target molecules) to facilitate separation of complexed from uncomplexed forms of one or both of the proteins, as well as to accommodate automation of the assay. The ability of a test compound to modulate Dicer interactor polypeptide activity, Dicer polypeptide activity, interaction of a Dicer interactor polypeptide with a Dicer polypeptide (or target interaction or activity) in the presence and absence of a candidate compound, can be accomplished in any vessel suitable for containing the reactants. Examples of such vessels include microtitre plates, test tubes, and micro-centrifuge tubes. In one embodiment, a fusion protein can be provided so as to add a domain that allows one or both of the proteins to be bound to a matrix. For example, glutathione-S-transferase/Dicer interactor fusion proteins, glutathione-S-transferase/Dicer fusion proteins, or target fusion proteins can be adsorbed onto glutathione sepharose beads (Sigma Chemical, St. Louis, Mo.) or glutathione derivatized microtitre plates, which are then combined with the test compound or the test compound and either the non-adsorbed Dicer polypeptide or Dicer interactor polypeptide (or target polypeptide), and the mixture incubated under conditions conducive to complex formation (e.g., at physiological conditions for salt and pH). Following incubation, the beads or microtitre plate wells are washed to remove any unbound components, the matrix immobilized in the case of beads, complex determined either directly or indirectly, for example, as described above. Alternatively, the complexes can be dissociated from the matrix, and the level of Dicer interactor binding or activity or Dicer binding or activity (or target binding or activity) determined using standard techniques.


Additional exemplary Dicer and/or Dicer interactor fusion proteins (or target fusion proteins) include, but are not limited to, chitin binding domain (CBD) fusion proteins, hemagglutinin epitope tagged (HA)-fusion proteins, His fusion proteins (e.g., His6 tagged proteins), FLAG tagged fusion proteins, AU1 tagged proteins, and the like.


Other techniques for immobilizing proteins on matrices can also be used in the screening assays of the invention. For example, either a Dicer polypeptide, a Dicer interactor polypeptide or target polypeptide can be immobilized utilizing conjugation of biotin and streptavidin. Biotinylated Dicer polypeptide, Dicer interactor polypeptide or target polypeptide can be prepared from biotin-NHS (N-hydroxy-succinimide) using techniques well known in the art (e.g., biotinylation kit, Pierce Chemicals, Rockford, Ill.), and immobilized in the wells of streptavidin-coated 96 well plates (Pierce Chemical). Alternatively, antibodies reactive with Dicer polypeptide, Dicer interactor polypeptide or target polypeptide but which do not interfere with binding of the Dicer interactor polypeptide to Dicer polypeptide (or protein to target binding) can be derivatized to the wells of the plate, and unbound Dicer or Dicer interactor polypeptide (or target) trapped in the wells by antibody conjugation. Methods for detecting such complexes, in addition to those described above for the GST-immobilized complexes, include immunodetection of complexes using antibodies reactive with the Dicer interactor polypeptide, Dicer polypeptide or target polypeptide, as well as enzyme-linked assays which rely on detecting an enzymatic activity associated with the Dicer interactor polypeptide, Dicer polypeptide or target polypeptide.


In one aspect of the invention, the Dicer interactor or Dicer polypeptides can be used as “bait proteins” in a two-hybrid assay or three-hybrid assay (see, e.g., U.S. Pat. No. 5,283,317; Zervos et al. (1993) Cell 72:223-232; Madura et al. (1993) J. Biol. Chem. 268:12046-12054; Bartel et al. (1993) Biotechniques 14:920-924; Iwabuchi et al. (1993) Oncogene 8:1693-1696; and Brent WO94/10300), to identify other proteins, which bind to or interact with Dicer interactor or Dicer (“binding proteins” or “target molecules”) and are involved in Dicer interactor or Dicer activity. Such target molecules are also likely to be involved in the regulation of cellular activities modulated by the Dicer interactor polypeptides or Dicer polypeptides.


At least one exemplary two-hybrid system is based on the modular nature of most transcription factors, which consist of separable DNA-binding and activation domains. Briefly, the assay utilizes two different DNA constructs. In one construct, the gene that codes for a first polypeptide (the “bait” polypeptide, e.g., Dicer or Dicer protein) is fused to a gene encoding the DNA binding domain of a known transcription factor (e.g., GAL-4). In the other construct, a DNA sequence, from a library of DNA sequences, that encodes an unidentified protein (“prey” or “sample”) is fused to a gene that codes for the activation domain of the known transcription factor. If the “bait” and the “prey” proteins are able to interact, in vivo, the DNA-binding and activation domains of the transcription factor are brought into close proximity. This proximity allows transcription of a reporter gene (e.g., LacZ) which is operably linked to a transcriptional regulatory site responsive to the transcription factor. Expression of the reporter gene can be detected and cell colonies containing the functional transcription factor can be isolated and used to obtain the cloned gene that encodes the protein that interacts with the bait polypeptide.


Another exemplary two-hybrid system, referred to in the art as the CytoTrap™ system, is based in the modular nature of molecules of the Ras signal transduction cascade. Briefly, the assay features a fusion protein comprising the “bait” protein and Son-of-Sevenless (SOS) and the cDNAs for unidentified proteins (the “prey”) in a vector that encodes myristylated target proteins. Expression of an appropriate bait-prey combination results in translocation of SOS to the cell membrane where it activates Ras. Cytoplasmic reconstitution of the Ras signaling pathway allows identification of proteins that interact with the bait protein of interest, for example, a Dicer or Dicer interactor protein. Additional mammalian two hybrid systems are also known in the art and can be utilized to identify Dicer or Dicer interactor interacting proteins. Moreover, at least one of the above-described assays can be utilized to identify Dicer-interacting domains or regions of the Dicer interactor protein or alternatively, to identify Dicer protein-interacting domain or regions of the Dicer protein.


VB. Cell or Organism Based Assays


In one embodiment, an assay is a cell or organism-based assay in which a cell or organism capable of expressing a Dicer interactor polypeptide, or biologically active portion thereof, is contacted with a test compound and the ability of the test compound to modulate the expression of the Dicer interactor polypeptide, or biologically active portion thereof, determined. In another embodiment, an assay is a cell or organism-based assay in which a cell or organism which expresses a Dicer interactor polypeptide or Dicer polypeptide (or biologically active portions thereof) is contacted with a test compound and the ability of the test compound to modulate the activity of the Dicer interactor polypeptide or Dicer polypeptide (or biologically active portions thereof) determined. The cell, for example, can be of mammalian origin or a yeast cell. The organism can be a nematode, for example, C. elegans or C. briggsae or D. melanogaster. The polypeptides, for example, can be expressed heterologously or native to the cell or organism. Determining the ability of the test compound to modulate the activity of a Dicer interactor or Dicer polypeptide (or biologically active portions thereof) can be accomplished by assaying for any of the activities of a Dicer interactor or Dicer polypeptide described herein. Determining the ability of the test compound to modulate the activity of a Dicer interactor polypeptide or Dicer polypeptide (or biologically active portions thereof) can also be accomplished by assaying for the activity of a Dicer downstream molecule. In one embodiment, determining the ability of the test compound to modulate the activity of a Dicer interactor polypeptide, or biologically active portion thereof, is accomplished by assaying for the ability to bind Dicer or a bioactive portion thereof. In another embodiment, determining the ability of the test compound to modulate the activity of a Dicer interactor polypeptide, or biologically active portion thereof, is accomplished by assaying for the activity of the Dicer interactor polypeptide. In a preferred embodiment, the cell or organism overexpresses the Dicer interactor polypeptide, or biologically active portion thereof, and optionally, overexpresses Dicer, or biologically active portion thereof. In another preferred embodiment, the cell or organism expresses Dicer, or biologically active portion thereof. In yet another preferred example, the cell or organism is contacted with a compound that stimulates a Dicer protein-associated activity or Dicer-associated activity and the ability of a test compound to modulate the Dicer protein-associated activity is determined.


As used herein, the term “bioactive” fragment includes any portion (e.g., a segment of contiguous amino acids) of a Dicer interactor or Dicer protein sufficient to exhibit or exert at least one Dicer protein- or Dicer-associated activity including, for example, the ability to bind to Dicer or Dicer protein, respectively. In various embodiments, the Dicer may be one of two isoforms, Dicer1 or Dicer2. In another embodiment, the bioactive peptide is derived from the amino acid sequence of Dicer. In another embodiment, the bioactive peptide corresponds to a fragment or domain as set forth in subsections IA-IEE, supra or a smaller bioactive fragment thereof. In another embodiment, the bioactive peptide is derived from a Dicer interactor and can include, for example, amino acid residues sufficient to effect enzymatic or nucleic acid-binding activity.


According to the cell or organism-based assays of the present invention, determining the ability of the test compound to modulate the activity of the Dicer polypeptide or biologically active portion thereof, can be determined by assaying for any of the native activities of a Dicer polypeptide as described herein. Moreover, the activity of Dicer, can be determined by assaying for an indirect activity which is coincident to the activity of Dicer. Furthermore, determining the ability of the test compound to modulate the activity of the Dicer and/or Dicer interactor polypeptide or biologically active portion thereof, can be determined by assaying for an activity which is not native to the Dicer interactor or Dicer polypeptide, but for which the cell or organism has been recombinantly engineered. For example, the cell or organism can be engineered to express a target molecule which is a recombinant protein comprising a bioactive portion of Dicer operatively linked to a non-Dicer polypeptide or a bioactive portion of a Dicer interactor operatively linked to a non-Dicer interactor polypeptide. It is also intended that in preferred embodiments, the cell or organism-based assays of the present invention comprise a final step of identifying the compound as a modulator of Dicer interactor activity or Dicer activity.

VIB. Antibodies Bioactive Fragments and Fusion Proteins


Preferred aspects of the invention feature Dicer polypeptides, Dicer interactor polypeptides and biologically active portions (i.e., bioactive fragments) of Dicer polypeptides or Dicer interactor polypeptides, including polypeptide fragments suitable for use in making Dicer interactor or Dicer fusion proteins. In one embodiment, Dicer polypeptides or Dicer interactor polypeptides can be isolated from cells or tissue sources by an appropriate purification scheme using standard protein purification techniques. Dicer polypeptide or Dicer interactor polypeptides can be further derived from said isolated polypeptides using standard enzymatic techniques. In another embodiment, Dicer interactor polypeptides, Dicer polypeptides or bioactive fragments thereof are produced by recombinant DNA techniques. Alternative to recombinant expression, Dicer interactor polypeptides, Dicer polypeptides or bioactive fragments thereof can be synthesized chemically using standard peptide synthesis techniques.


Polypeptides of the invention are preferably “isolated” or “purified”. The terms “isolated” and “purified” are used interchangeably herein. “Isolated” or “purified” means that the protein or polypeptide is substantially free of cellular material or other contaminating proteins from the cell or tissue source from which the polypeptide is derived, substantially free of other protein fragments, for example, non-desired fragments in a digestion mixture, or substantially free from chemical precursors or other chemicals when chemically synthesized. The language “substantially free of cellular material” includes preparations in which the polypeptide is separated from other components of the cells from which it is isolated or recombinantly produced. In one embodiment, the language “substantially free of cellular material” includes preparations of polypeptide having less than about 30% (by dry weight) of non-Dicer interactor or non-Dicer polypeptide (also referred to herein as a “contaminating protein”), more preferably less than about 20% of non-Dicer interactor or non-Dicer polypeptide, still more preferably less than about 10% of non-Dicer interactor or non-Dicer polypeptide, and most preferably less than about 5% non-Dicer interactor or non-Dicer polypeptide. When the polypeptide or protein is recombinantly produced, it is also preferably substantially free of culture medium, i.e., culture medium represents less than about 20%, more preferably less than about 10%, and most preferably less than about 5% of the volume of the polypeptide preparation. When the polypeptide or protein is produced by, for example, chemical or enzymatic processing from isolated or purified Dicer interactor or Dicer protein, the preparation is preferably free of enzyme reaction components or chemical reaction components and is free of non-desired Dicer interactor or Dicer fragments, i.e., the desired polypeptide represents at least 75% (by dry weight) of the preparation, preferably at least 80%, more preferably at least 85%, and even more preferably at least 90%, 95%, 99% or more or the preparation.


The language “substantially free of chemical precursors or other chemicals” includes preparations of polypeptide in which the polypeptide is separated from chemical precursors or other chemicals which are involved in the synthesis of the polypeptide. In one embodiment, the language “substantially free of chemical precursors or other chemicals” includes preparations having less than about 30% (by dry weight) of chemical precursors or reagents, more preferably less than about 20% chemical precursors or reagents, still more preferably less than about 10% chemical precursors or reagents, and most preferably less than about 5% chemical precursors or reagents.


Bioactive fragments of Dicer interactor or Dicer include polypeptides comprising amino acid sequences sufficiently identical to or derived from the amino acid sequence of the Dicer interactor protein or the Dicer protein, respectively, which include less amino acids than the full length protein, and exhibit at least one biological activity of the full-length protein. Typically, biologically active portions comprise a domain or motif with at least one activity of the full-length protein. A biologically active portion of a Dicer interactor or Dicer polypeptide can be a polypeptide which is, for example, 10, 20, 30, 40, 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1000 or more amino acids in length. In a preferred embodiment, a bioactive portion of a Dicer protein comprises a portion comprising a Dicer interactor interacting domain. Moreover, other biologically active portions, in which other regions of the protein are deleted, can be prepared by recombinant techniques and evaluated for one or more of the functional activities of a native Dicer interactor or Dicer protein. Mutants of Dicer and/or Dicer interactors can also be utilized as assay reagents, for example, mutants having reduced, enhanced or otherwise altered biological properties identified according to one of the activity assays described herein.


As defined herein, a Dicer polypeptide or Dicer interactor polypeptide of the invention includes polypeptides having the amino acid sequences set forth in subsections IA-IMM or II, infra, as well as homologs an/or orthologs of said polypeptides, i.e. polypeptides having sufficient sequence identity to function in the same manner as the described polypeptides. To determine the percent identity of two amino acid sequences (or of two nucleotide or amino acid sequences), the sequences are aligned for optimal comparison purposes (e.g., gaps can be introduced in the first sequence or second sequence for optimal alignment). The amino acid residues or nucleotides at corresponding amino acid positions or nucleotide positions are then compared. When a position in the first sequence is occupied by the same residue as the corresponding position in the second sequence, then the molecules are identical at that position. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences (i.e., % homology=# of identical positions/total # of positions×100), optionally penalizing the score for the number of gaps introduced and/or length of gaps introduced.


The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm. In one embodiment, the alignment generated over a certain portion of the sequence aligned having sufficient identity but not over portions having low degree of identity (i.e., a local alignment). A preferred, non-limiting example of a local alignment algorithm utilized for the comparison of sequences is the algorithm of Karlin and Altschul (1990) Proc. Natl. Acad Sci. USA 87:2264-68, modified as in Karlin and Altschul (1993) Proc. Natl. Acad. Sci. USA 90:5873-77. Such an algorithm is incorporated into the BLAST programs (version 2.0) of Altschul, et al. (1990) J. Mol. Biol. 215:403-10. BLAST alignments can be generated and percent identity calculated using BLAST protein searches (e.g., the XBLAST program) using Dicer protein, Dicer or a portion thereof as a query, score=50, wordlength=3.


In another embodiment, the alignment is optimized by introducing appropriate gaps and percent identity is determined over the length of the aligned sequences (i.e., a gapped alignment). To obtain gapped alignments for comparison purposes, Gapped BLAST can be utilized as described in Altschul et al., (1997) Nucleic Acids Research 25(17):3389-3402. In another embodiment, the alignment is optimized by introducing appropriate gaps and percent identity is determined over the entire length of the sequences aligned (i.e., a global alignment). A preferred, non-limiting example of a mathematical algorithm utilized for the global comparison of sequences is the algorithm of Myers and Miller, CABIOS (1989). Such an algorithm is incorporated into the ALIGN program (version 2.0) which is part of the GCG sequence alignment software package. When utilizing the ALIGN program for comparing amino acid sequences, a PAM120 weight residue table, a gap length penalty of 12, and a gap penalty of 4 can be used.


The invention also provides Dicer interactors and Dicer chimeric or fusion proteins. As used herein, a Dicer interactor or Dicer “chimeric protein” or “fusion protein” comprises a Dicer interactor or Dicer polypeptide operatively linked to a non-Dicer interactor polypeptide or non-Dicer polypeptide, respectively. A “Dicer interactor polypeptide” or “Dicer polypeptide” refers to a polypeptide having an amino acid sequence corresponding to the Dicer interactor or Dicer protein, respectively, whereas a “non-Dicer interactor polypeptide” or “non-Dicer polypeptide” refers to a polypeptide having an amino acid sequence corresponding to a protein which is not substantially identical to the Dicer interactor protein or Dicer protein. Within a fusion protein the Dicer interactor or Dicer polypeptide can correspond to all or a portion of a Dicer interactor or Dicer protein. In a preferred embodiment, a Dicer interactor or Dicer fusion protein comprises at least one biologically active portion of a Dicer interactor or Dicer protein, respectively. In another preferred embodiment, a Dicer interactor or Dicer fusion protein comprises at least two biologically active portions of a Dicer interactor or Dicer protein, respectively. In yet another preferred embodiment, a fusion protein can comprise Dicer protein, or a bioactive portion thereof, operatively linked to Dicer, or a bioactive portion thereof, such that Dicer interactor and Dicer, or their respective bioactive portions are brought into close proximity. Within the fusion protein, the term “operatively linked” is intended to indicate that the Dicer interactor or Dicer polypeptide and the non-Dicer interactor polypeptide or non-Dicer polypeptide are fused in-frame to each other. The non-Dicer interactor polypeptide or non-Dicer polypeptide can be fused to the N-terminus or C-terminus of the Dicer interactor polypeptide or Dicer polypeptide, respectively.


For example, in one embodiment, the fusion protein is a GST-fusion protein in which the Dicer interactor or Dicer sequences are fused to the C-terminus of the GST sequences. In another embodiment, the fusion protein is a chitin binding domain (CBD) fusion protein in which the Dicer interactor or Dicer sequences are fused to the N-terminus of chitin binding domain (CBD) sequences. Such fusion proteins can facilitate the purification of recombinant Dicer interactor or Dicer.


Preferably, a chimeric or fusion protein of the invention is produced by standard recombinant DNA techniques. For example, DNA fragments coding for the different polypeptide sequences are ligated together in-frame in accordance with conventional techniques, for example by employing blunt-ended or stagger-ended termini for ligation, restriction enzyme digestion to provide for appropriate termini, filling-in of cohesive ends as appropriate, alkaline phosphatase treatment to avoid undesirable joining, and enzymatic ligation. In another embodiment, the fusion gene can be synthesized by conventional techniques including automated DNA synthesizers. Alternatively, PCR amplification of gene fragments can be carried out using anchor primers which give rise to complementary overhangs between two consecutive gene fragments which can subsequently be annealed and reamplified to generate a chimeric gene sequence (see, for example, Current Protocols in Molecular Biology, eds. Ausubel et al. John Wiley & Sons: 1992). Moreover, many expression vectors are commercially available that already encode a fusion moiety. A Dicer protein- or Dicer-encoding nucleic acid can be cloned into such an expression vector such that the fusion moiety is linked in-frame to the Dicer interactor or Dicer polypeptide.


A Dicer interactor polypeptide or Dicer polypeptide, or a portion or fragment of Dicer interactor or Dicer, can also be used as an immunogen to generate antibodies that bind Dicer interactor or Dicer or that block Dicer protein/Dicer binding using standard techniques for polyclonal and monoclonal antibody preparation. A full-length polypeptide can be used or, alternatively, the invention provides antigenic peptide fragments for use as immunogens. Preferably, an antigenic fragment comprises at least 8 amino acid residues of the amino acid sequence of a Dicer interactor or Dicer and encompasses an epitope of Dicer interactor or Dicer such that an antibody raised against the peptide forms a specific immune complex with Dicer interactor or Dicer, respectively. Preferably, the antigenic peptide comprises at least 10 amino acid residues, more preferably at least 15 amino acid residues, even more preferably at least 20 amino acid residues, and most preferably at least 30 amino acid residues. Preferred epitopes encompassed by the antigenic peptide are regions of Dicer interactor or Dicer that are located on the surface of the protein, e.g., hydrophilic regions. Antigenic determinants at the termini of Dicer interactor are preferred for the development of antibodies that do not interfere with the Dicer protein:Dicer interaction. Alternatively, interfering antibodies can be generated towards antigenic determinants located within the Dicer interacting domain of Dicer protein. The latter are preferred for therapeutic purposes.


A Dicer interactor or Dicer immunogen typically is used to prepare antibodies by immunizing a suitable subject, (e.g., rabbit, goat, mouse or other mammal) with the immunogen. An appropriate immunogenic preparation can contain, for example, recombinantly expressed Dicer interactor or Dicer polypeptide or a chemically synthesized Dicer interactor or Dicer polypeptide. The preparation can further include an adjuvant, such as Freund's complete or incomplete adjuvant, or similar immunostimulatory agent. Immunization of a suitable subject with an immunogenic Dicer interactor or Dicer preparation induces a polyclonal anti-Dicer interactor or anti-Dicer antibody response, respectively.


Accordingly, another aspect of the invention pertains to anti-Dicer interactor or anti-Dicer antibodies. The term “antibody” as used herein refers to immunoglobulin molecules and immunologically active portions of immunoglobulin molecules, i.e., molecules that contain an antigen binding site which specifically binds (immunoreacts with) an antigen, such as Dicer interactor or Dicer. Examples of immunologically active portions of immunoglobulin molecules include F(ab) and F(ab+)2 fragments which can be generated by treating the antibody with an enzyme such as pepsin. The invention provides polyclonal and monoclonal antibodies that bind Dicer protein. The term “monoclonal antibody” or “monoclonal antibody composition”, as used herein, refers to a population of antibody molecules that contain only one species of an antigen binding site capable of immunoreacting with a particular epitope of Dicer interactor or Dicer. A monoclonal antibody composition thus typically displays a single binding affinity for a particular Dicer interactor or Dicer polypeptide with which it immunoreacts.


Polyclonal anti-Dicer interactor or anti-Dicer antibodies can be prepared as described above by immunizing a suitable subject with a Dicer interactor or Dicer immunogen, respectively. The antibody titer in the immunized subject can be monitored over time by standard techniques, such as with an enzyme linked immunosorbent assay (ELISA) using immobilized Dicer interactor or Dicer. If desired, the antibody molecules can be isolated from the mammal (e.g., from the blood) and further purified by well known techniques, such as protein A chromatography to obtain the IgG fraction. At an appropriate time after immunization, e.g., when the anti-Dicer interactor or anti-Dicer antibody titers are highest, antibody-producing cells can be obtained from the subject and used to prepare monoclonal antibodies by standard techniques, such as the hybridoma technique originally described by Kohler and Milstein (1975) Nature 256:495-497) (see also, Brown et al. (1981) J. Immunol. 127:539-46; Brown et al. (1980) J. Biol. Chem. 255:4980-83; Yeh et al. (1976) PNAS 76:2927-31; and Yeh et al. (1982) Int. J. Cancer 29:269-75), the more recent human B cell hybridoma technique (Kozbor et al. (1983) Immunol Today 4:72), the EBV-hybridoma technique (Cole et al. (1985), Monoclonal Antibodies and Cancer Therapy, Alan R. Liss, Inc., pp. 77-96) or trioma techniques. The technology for producing monoclonal antibody hybridomas is well known (see generally R. H. Kenneth, in Monoclonal Antibodies: A New Dimension In Biological Analyses, Plenum Publishing Corp., New York, N.Y. (1980); E. A. Lerner (1981) Yale J. Biol. Med., 54:387-402; M. L. Gefter et al. (1977) Somatic Cell Genet. 3:231-36). Briefly, an immortal cell line (typically a myeloma) is fused to lymphocytes (typically splenocytes) from a mammal immunized with a Dicer interactor or Dicer immunogen as described above, and the culture supernatants of the resulting hybridoma cells are screened to identify a hybridoma producing a monoclonal antibody that binds Dicer interactor or Dicer, respectively.


Any of the many well known protocols used for fusing lymphocytes and immortalized cell lines can be applied for the purpose of generating an anti-Dicer interactor monoclonal antibody (see, e.g., G. Galfre et al. (1977) Nature 266:55052; Gefter et al. Somatic Cell Genet., cited supra; Lerner, Yale J. Biol. Med., cited supra; Kenneth, Monoclonal Antibodies, cited supra). Moreover, the ordinarily skilled worker will appreciate that there are many variations of such methods which also would be useful. Typically, the immortal cell line (e.g., a myeloma cell line) is derived from the same mammalian species as the lymphocytes. For example, murine hybridomas can be made by fusing lymphocytes from a mouse immunized with an immunogenic preparation of the present invention with an immortalized mouse cell line. Preferred immortal cell lines are mouse myeloma cell lines that are sensitive to culture medium containing hypoxanthine, aminopterin and thymidine (“HAT medium”). Any of a number of myeloma cell lines can be used as a fusion partner according to standard techniques, e.g., the P3-NS1/1-Ag4-1, P3-x63-Ag8.653 or Sp2/O-Ag14 myeloma lines. These myeloma lines are available from ATCC. Typically, HAT-sensitive mouse myeloma cells are fused to mouse splenocytes using polyethylene glycol (“PEG”). Hybridoma cells resulting from the fusion are then selected using HAT medium, which kills unfused and unproductively fused myeloma cells (unfused splenocytes die after several days because they are not transformed). Hybridoma cells producing a monoclonal antibody of the invention are detected by screening the hybridoma culture supernatants for antibodies that bind Dicer interactor or Dicer, e.g., using a standard ELISA assay.


Alternative to preparing monoclonal antibody-secreting hybridomas, a monoclonal anti-Dicer interactor or anti-Dicer antibody can be identified and isolated by screening a recombinant combinatorial immunoglobulin library (e.g., an antibody phage display library) with Dicer interactor or Dicer to thereby isolate immunoglobulin library members that bind Dicer interactor or Dicer, respectively. Kits for generating and screening phage display libraries are commercially available (e.g., the Pharmacia Recombinant Phage Antibody System, Catalog No. 27-9400-01; and the Stratagene SurfZAP™ Phage Display Kit, Catalog No. 240612). Additionally, examples of methods and reagents particularly amenable for use in generating and screening antibody display library can be found in, for example, Ladner et al. U.S. Pat. No. 5,223,409; Kang et al. PCT International Publication No. WO 92/18619; Dower et al. PCT International Publication No. WO 91/17271; Winter et al. PCT International Publication WO 92/20791; Markland et al. PCT International Publication No. WO 92/15679; Breitling et al. PCT International Publication WO 93/01288; McCafferty et al.

Mol. Biol. 226:889-896; Clarkson et al. (1991) Nature 352:624-628; Gram et al. (1992) PNAS 89:3576-3580; Garrad et al. (1991) Bio/Technology 9:1373-1377; Hoogenboom et al. (1991) Nuc. Acid Res. 19:4133-4137; Barbas et al. (1991) PNAS 88:7978-7982; and McCafferty et al. Nature (1990) 348:552-554.


An anti-Dicer interactor or anti-Dicer antibody (e.g., monoclonal antibody) can be used to isolate Dicer interactor or Dicer, bioactive portions thereof, or fusion proteins by standard techniques, such as affinity chromatography or immunoprecipitation. Anti-Dicer antibodies or anti-Dicer interactor antibodies made according to any of the above-described techniques can be used to detect protein levels in donor or acceptor fractions as part of certain assay methodologies described herein. Detection can be facilitated by coupling (i.e., physically linking) the antibody to a detectable substance. Examples of detectable substances include various enzymes, prosthetic groups, fluorescent materials, luminescent materials, bioluminescent materials, and radioactive materials. Examples of suitable enzymes include horseradish peroxidase, alkaline phosphatase, -galactosidase, or acetylcholinesterase; examples of suitable prosthetic group complexes include streptavidin/biotin and avidin/biotin; examples of suitable fluorescent materials include umbelliferone, fluorescein, fluorescein isothiocyanate, rhodamine, dichlorotriazinylamine fluorescein, dansyl chloride or phycoerythrin; an example of a luminescent material includes luminol; examples of bioluminescent materials include luciferase, luciferin, and aequorin, and examples of suitable radioactive material include 125I, 131I, 35S or 3H.


VIC. Recombinant Expression Vectors and Assay Cells or Organisms


Another aspect of the invention pertains to vectors, preferably expression vectors, for producing the proteins reagents of the instant invention. As used herein, the term “vector” refers to a nucleic acid molecule capable of transporting another nucleic acid to which it has been linked. A preferred vector is a “plasmid”, which refers to a circular double stranded DNA loop into which additional DNA segments can be ligated. In the present specification, “plasmid” and “vector” can be used interchangeably as the plasmid is the most commonly used form of vector.


The recombinant expression vectors of the invention comprise a nucleic acid that encodes, for example protein or Dicer or a bioactive fragment or Dicer interactor or bioactive fragment, in a form suitable for expression of the nucleic acid in a host cell or organism, which means that the recombinant expression vectors include one or more regulatory sequences, selected on the basis of the host cells or organisms to be used for expression, which is operatively linked to the nucleic acid sequence to be expressed. Within a recombinant expression vector, “operably linked” is intended to mean that the nucleotide sequence of interest is linked to the regulatory sequence(s) in a manner which allows for expression of the nucleotide sequence (e.g., in an in vitro transcription/translation system or in a host cell or organism when the vector is introduced into the host cell or organism). The term “regulatory sequence” is intended to includes promoters, enhancers and other expression control elements (e.g., polyadenylation signals). The expression vectors can be introduced into host cell or organisms to thereby produce proteins, including fusion proteins or peptides. Alternatively, retroviral expression vectors and/or adenoviral expression vectors can be utilized to express the proteins of the present invention.


The recombinant expression vectors of the invention can be designed for expression of Dicer interactor or Dicer polypeptides in prokaryotic or eukaryotic cells. For example, Dicer interactor or Dicer polypeptides can be expressed in bacterial cells such as E. coli, insect cells (using baculovirus expression vectors) yeast cells or mammalian cells. Suitable host cells are discussed further in Goeddel, Gene Expression Technology: Methods in Enzymology 185, Academic Press, San Diego, Calif. (1990).


Expression of proteins in prokaryotes is most often carried out in E. coli with vectors containing constitutive or inducible promoters directing the expression of either fusion or non-fusion proteins. Fusion vectors add a number of amino acids to a protein encoded therein, usually to the amino terminus of the recombinant protein. Such fusion vectors typically serve three purposes: 1) to increase expression of recombinant protein; 2) to increase the solubility of the recombinant protein; and 3) to aid in the purification of the recombinant protein by acting as a ligand in affinity purification. Often, in fusion expression vectors, a proteolytic cleavage site is introduced at the junction of the fusion moiety and the recombinant protein to enable separation of the recombinant protein from the fusion moiety subsequent to purification of the fusion protein. Purified fusion proteins are particularly useful in the cell-free assay methodologies of the present invention.


In yet another embodiment, a protein or Dicer-encoding or Dicer-protein-encoding nucleic acid is expressed in mammalian cells, for example, for use in the cell or organism-based assays described herein. When used in mammalian cells, the expression vector's control functions are often provided by viral regulatory elements. In another embodiment, the recombinant mammalian expression vector is capable of directing expression of the nucleic acid preferentially in a particular cell type (e.g., tissue-specific regulatory elements are used to express the nucleic acid).


Another aspect of the invention pertains to assay cells into which a recombinant expression vector has been introduced. An assay cell can be prokaryotic or eukaryotic, but preferably is eukaryotic. Cell lines are cultured according to art-recognized techniques. Vector DNA can be introduced into prokaryotic or eukaryotic cells via conventional transformation or transfection techniques. Suitable methods for transforming or transfecting host cells can be found in Sambrook, et al. (Molecular Cloning: A Laboratory Manual. 2nd, ed., Cold Spring Harbor Laboratory, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1989), and other laboratory manuals. An assay cell of the invention, can be contacted with a test compound and assayed for any Dicer interactor and/or Dicer biological activity in order to identify the compound as a modulator. Biological activities that can further be assayed as part of the methodologies of the present invention include, but are not limited to, (1) processing of miRNA precursors; (2) processing of siRNA precursors; (3) mediating mRNA cleavage; (4) mediating assembly of RISC (e.g., via siRNAs); (5) directing translation repression (e.g., via miRNAs); (6) a ribonuclease activity (e.g., cleavage of dsRNA); and (7) initiation of RNAi. In addition, other biological activities which may be assayed for include those listed in Table 1 and/or subsections IA-IMM and II, supra.


VII. Pharmaceutical Compositions


This invention further pertains to modulators identified by the above-described screening assays. Modulators identified by the above-described screening assays can be tested in an appropriate animal model. For example, a Dicer modulator, RNAi modulator and/or gene silencing modulator identified as described herein can be used in an animal model to determine the efficacy, toxicity, or side effects of treatment with such a modulator. Alternatively, a modulator identified as described herein can be used in an animal model to determine the mechanism of action of such an agent. Furthermore, this invention pertains to uses of modulators identified by the above-described screening assays for therapeutic treatments as described infra.


Accordingly, the modulators of the present invention can be incorporated into pharmaceutical compositions suitable for administration. Such compositions typically comprise the nucleic acid molecule, protein, antibody, or modulatory compound and a pharmaceutically acceptable carrier. As used herein the language “pharmaceutically acceptable carrier” is intended to include any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like, compatible with pharmaceutical administration. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active compound, use thereof in the compositions is contemplated. Supplementary active compounds can also be incorporated into the compositions.


A pharmaceutical composition of the invention is formulated to be compatible with its intended route of administration. Examples of routes of administration include parenteral, e.g., intravenous, intradermal, subcutaneous, oral (e.g., inhalation), transdermal (topical), transmucosal, and rectal administration. Solutions or suspensions used for parenteral, intradermal, or subcutaneous application can include the following components: a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid; buffers such as acetates, citrates or phosphates and agents for the adjustment of tonicity such as sodium chloride or dextrose. pH can be adjusted with acids or bases, such as hydrochloric acid or sodium hydroxide. The parenteral preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic.


Pharmaceutical compositions suitable for injectable use include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor EL™ (BASF, Parsippany, N.J.) or phosphate buffered saline (PBS). In all cases, the composition must be sterile and should be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyetheylene glycol, and the like), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as manitol, sorbitol, sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.


Sterile injectable solutions can be prepared by incorporating the active compound in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle which contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and freeze-drying which yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.


Oral compositions generally include an inert diluent or an edible carrier. They can be enclosed in gelatin capsules or compressed into tablets. For the purpose of oral therapeutic administration, the active compound can be incorporated with excipients and used in the form of tablets, troches, or capsules. Oral compositions can also be prepared using a fluid carrier for use as a mouthwash, wherein the compound in the fluid carrier is applied orally and swished and expectorated or swallowed. Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of the composition. The tablets, pills, capsules, troches and the like can contain any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate or Sterotes; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring.


For administration by inhalation, the compounds are delivered in the form of an aerosol spray from pressured container or dispenser which contains a suitable propellant, e.g., a gas such as carbon dioxide, or a nebulizer.


Systemic administration can also be by transmucosal or transdermal means. For transmucosal or transdermal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art, and include, for example, for transmucosal administration, detergents, bile salts, and fusidic acid derivatives. Transmucosal administration can be accomplished through the use of nasal sprays or suppositories. For transdermal administration, the active compounds are formulated into ointments, salves, gels, or creams as generally known in the art.


The compounds can also be prepared in the form of suppositories (e.g., with conventional suppository bases such as cocoa butter and other glycerides) or retention enemas for rectal delivery.


In one embodiment, the active compounds are prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art. The materials can also be obtained commercially from Alza Corporation and Nova Pharmaceuticals, Inc. Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to viral antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811.


It is especially advantageous to formulate oral or parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the invention are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and the limitations inherent in the art of compounding such an active compound for the treatment of individuals.


Toxicity and therapeutic efficacy of such compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio LD50/ED50. Compounds which exhibit large therapeutic indices are preferred. While compounds that exhibit toxic side effects may be used, care should be taken to design a delivery system that targets such compounds to the site of affected tissue in order to minimize potential damage to uninfected cells and, thereby, reduce side effects.


The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. For any compound used in the method of the invention, the therapeutically effective dose can be estimated initially from cell culture assays. A dose may be formulated in animal models to achieve a circulating plasma concentration range that includes the IC50 (i.e., the concentration of the test compound which achieves a half-maximal inhibition of symptoms) as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Levels in plasma may be measured, for example, by high performance liquid chromatography.


The pharmaceutical compositions can be included in a container, pack, or dispenser together with instructions for administration.


VIII. Methods of Treatment


The present invention also features methods of treatment or therapeutic methods. In one embodiment, the invention features a method of treating a subject (e.g., a human subject in need thereof) with a modulatory compound identified according to the present invention, such that a desired therapeutic effect is achieved. In another embodiment, the method involves administering to an isolated tissue or cell line from the subject a modulatory compound identified according to the methodology described herein, such that a desired therapeutic effect is achieved. In a preferred embodiment, the invention features a method of treating a subject having a disease or disorder characterized by overexpression or aberrant expression of a particular protein. For example, positive modulators of Dicer and/or RNAi can be used to enhance RNAi of deleterious proteins. Likewise, negative modulators of Dicer and/or RNAi can be used to alleviate symptoms resulting from the RNAi pathway. Desired therapeutic effects include a modulation of any Dicer protein-, Dicer- or Dicer protein/Dicer-associated activity, as described herein. Desired therapeutic effects also include, but are not limited to curing or healing the subject, alleviating, relieving, altering or ameliorating a disease or disorder in the subject or at least one symptom of said disease or disorder in the subject, or otherwise improving or affecting the health of the subject. A preferred aspect of the invention pertains to methods of modulating Dicer protein/Dicer interactions for therapeutic purposes.


The modulators identified by the methods disclosed herein may be used in a subject to modulate (1) processing of miRNA precursors; (2) processing of siRNA precursors; (3) mediating mRNA cleavage; (4) mediating assembly of RISC (e.g., via siRNAs); (5) directing translation repression (e.g., via miRNAs); (6) a ribonuclease activity (e.g., cleavage of dsRNA); and/or (7) initiation of RNAi.


The effectiveness of treatment of a subject with a Dicer modulator, RNAi modulator and/or gene silencing modulator can be accomplished by (i) detecting the level of activity in the subject prior to treating with an appropriate modulator; (ii) detecting the level of activity in the subject post treatment with the modulator; (iii) comparing the levels pre-administration and post administration; and (iv) altering the administration of the modulator to the subject accordingly. For example, increased administration of the modulator may be desirable if the subject continues to demonstrate undesireable symptoms of the disease or disorder being treated.


IX. Diagnostic Assays


The present invention also features diagnostic assays, for determining aberrant Dicer protein:Dicer interaction, expression or activity, in the context of a biological sample (e.g., blood, serum, cells, tissue) to thereby determine whether an individual is afflicted with a disease or disorder associated with said aberrancy or is at risk of developing such a disorder. The invention also provides for prognostic (or predictive) assays for determining whether an individual is at risk of developing such a disorder (e.g., a disorder associated with aberrant Dicer interactor expression or activity). Such assays can be used for prognostic or predictive purpose to thereby prophylactically treat an individual prior to the onset of a disease or disorder. A preferred agent for detecting a Dicer interactor or Dicer protein is an antibody capable of binding to protein or Dicer, respectively, preferably an antibody with a detectable label. The term “biological sample” is intended to include tissues, cells and biological fluids isolated from a subject, as well as tissues, cells and fluids present within a subject. The invention also encompasses kits for the detection of aberrant Dicer protein:Dicer interaction, expression or activity in a biological sample. For example, the kit can comprise a labeled compound or agent capable of detecting Dicer interactor and/or Dicer in a biological sample; means for determining the amount of Dicer interactor and/or Dicer in the sample; and/or means for comparing the amount of Dicer interactor in the sample with a standard. The compound or agent can be packaged in a suitable container. The kit can further comprise instructions for using the kit.


X. Uses


The invention has several further advantageous uses which include, but are not limited to, the following: providing interacting proteins of Dicer and there use in modulating Dicer function; methods for identifying further interactors of Dicer and their structural and functional characteristics; method for regulating Dicer activity though the use of Dicer interactors; methods for improving the in vitro or in vivo processing of Dicer proteins or for as targets for pharmaceutical intervention in order to modulate the properties of Dicer in vivo for improved RNAi; and methods for stabilizing RNAi agents/compositions comprising Dicer by the addition of stabilizing interactor proteins or the same for use in purifying Dicer and other Dicer components.

C. elegans Strains


Typical C. elegans strains for carrying out the invention as described herein include, for example, N2; alg-2 strain (ok304); dcr-1 for rescue; dcr-1 counterselectable; f20 counterselectable; drh-3 counterselectable; bn-2 (glp-4); rde-4 ne337; eri-1 (mg366); rrf-3 (pk); eri-3 (tm); and eri-5 (mg, tm).


Antibody Development and Purification


Antisera against C. elegans Dicer, i.e., DCR-1, were raised in rabbits as described by Capralogics services (Capralogics, Hardwick, Mass., USA). The antisera used for the somatic purifications, and for the immunoblot analyses were developed using a fragment encoded by residues 1145 to 1347 of the protein fused to the pCal-KC (Stratagene) encoded fusion. For their affinity purification, another fragment encoding residues 966 to 1347 was expressed as a pET-42a (Novagen) fusion, purified under denaturing conditions, using Guanidine HCl (Ultra grade, FLUKA) 6M/150 mM NaCl/HEPES 25 mM pH 8.0 as a lysis, binding and washing buffer. The purified fusion was eluted in Guanidine HCl 6M/150 mM NaCl/MES 25 mM pH4.8 and added directly to the Affigel 10 (Biorad) and allowed to rock O/N for covalent coupling of the fusion.


The matrix was then washed in coupling buffer (5 column volumes) in Tris (10 column volumes) and remaining active sites were blocked using triethanolamine/HCl for 2 h at 4 degrees. The matrix was then rinsed extensively in PBS and used for affinity-purification of the antisera. The sera (4 ml per batch) were diluted 1:5 in PBS, filtered sterile and loaded directly on the prepared affinity matrixes. After batch binding, the beads were washed extensively with PBS in a column and, the antibodies were eluted (8 column volumes) using glycine 0.2M pH2.2, while harvesting the fractions if 3:7 volumes of Potassium Phosphate solution at pH10, to neutralize the fractions. Consecutive purifications (3) were realized with the same serum batch with similar antibody recovery.


Fractions were then examined by SDS-PAGE, and quantified by comparison with BSA standards. The fractions containing the antibodies were dialyzed against PBS/5% glycerol, and concentrated to ˜1 microgram per microliter using the Centricon 10 centrifuge dialysis system (Millipore). The concentrated antibodies were frozen at −80 until used.


Dicer (Dcr-1) Transgenic Rescue


A fragment encoding the 3′ portion of the Dicer (dcr-1) gene was cloned into Bluescript SK (Stratagene) and a Not I site was inserted prior to its stop codon. A NotI cassette encoding 8 copies of HA, and the yeast sup4o gene embedded in an artificial C. elegans intron was then inserted in frame at the 3′ portion of the recombination cassette. This fusion was then prepared by PCR and used to transform a yeast strain bearing the YAC Y97B3. The strain was then selected on URA-/LYS- for YAC recombinants.


Confirmed recombinants, were screened by PCR and a genomic preparation of the strain was realized. A C. elegans strain bearing dcr-1 (ok247), and the dpy-13 lesions balanced by the sDp-3 free duplication was used for rescue. The genomic DNA was injected in the balanced animals germline at 200 ng per microliter with an additional 50 ng per microliter of sur-5::gfp expressing vector, as a secondary marker for transformation. Mosaics (F1) were selected on the basis of their GFP signal, singled out, and transmitting lines were identified with regard of the GFP signal of the F2s.


Genomic DNA was then prepared from 2-5 animals of such lines, and examined for the presence of the recombinant YAC DNA by PCR. 4 out of 22 independent transgenic lines had the YAC, and of such, 2 of the strains consistently produced dpy animals with fertile progeny. Single picks from such animals led to dpy populations, in which only GFP+ animals were fertile thereby indicating that the rescue was due to the recombinant YAC.


Fractionation and Immunoblot Analysis


For the somatic purifications, and the RNA analysis, the C. elegans strains were grown in standard conditions, as synchronous populations and harvested as adults with a single row of embryos, or allowed to grow 12 h after the L4 to young adult transition, in the case of sterile animals. Animals were rinsed in M9 twice and floated on sucrose if gravid adults were used. Animals were allowed to rock in M9 for 30 min at RT to allow digestion of the gut bacterial load. For embryonic preparations, gravid adults were hypochlorided as previously described, rinsed in M9 three times, and further rinsed in cold water. The animals were then pelleted using a table-top falcon centrifuge, and frozen at −80° C. as a compacted pellet after all the supernatant was drained.


Preparations where further processed using one volume of hypotonic buffer, 10 mM HEPES KOAc pH 7.5; 10 mM K(OAc); 2 mM Mg(OAC)2; 1 mM DTT with 4× concentration complete protease inhibitors and RNase inhibitors. The suspension was then transferred to a cold Dounce homogenizer, and stroked 20-30 times, on ice. The resulting slurry was then transferred to an Eppendorf, and the recovered volume was adjusted to 110 mM KCl (yields Isotonic buffer), vortexed and allowed to sit on ice for 10 minutes.


The nuclear fraction was prepared in the following manner. The slurry was first centrifugation at 1500×g for 30 sec at 4°. The supernatant was recovered and adjusted to 10% glycerol, 0.01% Triton X-100, and vortexed and allowed to sit on ice for 10 min. The slurry was then loaded on a sucrose cushion (10 mM HEPES pH7.5; 10 mM KCl; 1M sucrose; 10% glycerol; 1 mM EDTA), and centrifuged at 20000×g for 10 min at 4°. The pellet yields the nuclear fraction.


The S100 and P100 fractions were prepared as follows. The supernatant from a short 1500×g centrifugation was further centrifuged at 10000×g for 10 min at 4°, and the supernatant was recovered (S10 fraction). This fraction was then loaded in a Beckman microfuge polyallomer tube and further spun 1 h 4° C. in a TLA100.3 to yield the S100 and P100 fractions. Equivalent volumes of each fraction was precipitated in 2 volumes acetone and resuspended in 1× SDS-PAGE buffer for the fraction analyses.


Immunoblots were realized using PBS/0.1% tween/5% milk for blocking and blotting, and PBS/0.1% tween for washings. Primary antibodies were incubated at RT for lh, and the corresponding HRP-coupled secondaries were used at 1:5000 for 1 h before 3× 5 min washes and ECL development (Pierce).


Purifications and Immunoprecipitations


Immunoprecipitation matrixes were prepared by DimethylPimeliimidate (DMP) (Sigma) covalent coupling to rProtA-agarose beads (Pierce) in sodium borate pH9.0 buffer. The beads were then stripped and blocked in 0.2M glycine pH2.2, rinsed extensively in PBS and kept until use at 4° C. with thymerosal as antibacterial agent. For typical preparations, 1 mg purified polyclonal antibodies were covalently coupled to 200 ul rProtA beads. In the case of embryonic purifications, agarose coupled matrixes from both antibody clones were used.


For the Dicer (DCR-1) purifications, the S100 fraction was further quantified and diluted to 3 mg per ml concentration in 1% Triton X-100 supplemented Isotonic buffer before the suitable buffer-equilibrated matrixes (30 ul bead volume per 2 ml IP) were added to the mixtures. Immunoprecipitations were carried out at 4° C. for 1 h, and beads were then washed 3 times in the immunoprecipitation buffer.


Immunoprecipitates were then treated with 20 ug per ml RNaseA for 30 minutes on ice in the same buffer, then washed three more times. The beads were washed one more time in cold PBS, and all the supernatant was drained. Bound proteins were eluted in 8M urea/50 mM HEPES pH7.5, and acetone-precipitated. ⅕th the elution volume was kept and monitored on silver stain and/or by immunoblot for a qualitative evaluation of the immunoprecipitation process.


RNA Interferences


Feeding and microinjection RNAi was carried out as previously reported by Conte Jr. D. and Mello, C. C. 2003. RNA interference in Caenorhabditis Elegans. In Current Protocols in Molecular Biology.


Northern Blotting and Real Time PCR


Small RNAs were prepared from N2(wt), bn2(glp4), which lack a germline tissue, and mutants for rde-4(ne337), rrf-3(pk1426), eri-1(mg366), eri-3(tm1361), and eri-5(mg370), all at 25° C. Homozygous dcr-1(ok247), f20d12.1, and drh-3(tm]217) sterile adult animals were isolated using the counterselectable genetic balancer method. For alg-1 and alg-2 depleted preparations, alg-2(ok204) L1 animals were exposed to an alg-1(rnai) feeding strain, and the bursting young adults were harvested and used for small RNA preparations. The isolated small RNA preparations were typically examined by Northern blotting for a variety of endogenous small RNAs as well as miR58, tncR7, and the X chromosome locus contig of small RNAs described in the art. Real time PCR was performed with primer pairs having efficiencies validated for a multiple 10 fold dilution range around the N2(wt) level, and fold changes were calculated using the delta delta Ct method.


Imaging and Video Microscopy


DAPI staining of intact animals was done as described in the art. Endomitotic (Emo) phenotype was scored by intense and irregular DAPI staining or expression of histoneH2::gfp in germ cell nuclei. Nematode gonads were dissected as described in the art with slight modifications. Briefly, young adult worms were placed in a drop of PBS containing 0.15 mM of levamisole on a glass slide for gonad extrusion. The dissected gonads were then fixed in 4% paraformaldehyde in PBS for 5 minutes, followed by three washes of PBS before staining with DAPI for 5 minutes. Gonads were then mounted for imaging after 3 washes with PBS. DIC or fluorescence images were collected by a Hamamatsu Ocre-ER digital camera mounted on a Zeiss Axioplan 2 under the control of Openlab 3.0 software. In time-lapse video microscopy experiments, young adult animals expressing a histoneH2::gfp fusion in the germline (AZ212) were cut open in M9 solution and embryos were mounted on 2% agarose pads in M9 solution for recording by a Leica TCS SP2 confocal microscope system. Movies were processed on a Macintosh computer using the public domain Image J 10.2 program (developed at the U.S. National Institutes of Health.


Multi Dimensional Protein Identification Technology


The MudPIT assays were performed essentially as described in Graumann et al., Mol Cell Proteomics, 3(3):226-37 (2004) and Liu et al., Biotechniques. 32(4):898, 900, 902 passim (2002).


EXAMPLE 1
Methods for Identifying Dicer Interacting Proteins

To identify Dicer interacting proteins a protenomic approach was employed. In particular, a combined and comparative proteomic approach was designed and used to identify novel factors implicated in molecular interactions with Dicer (DCR-1) in the nematode C. elegans. The approach featured a combined transgenic and immuno-biochemical purification scheme with an innovative Mass Spectrometry technology called MudPit (Multi-dimensional protein identification technology) in order to identify proteins interacting with DCR-1 in the embryo and in the adult of the animal and compared with the interactors identified in parallel as being interactors of the RDE-4 and RDE-1 proteins. The MudPit technology has been previously described (see, e.g., Graumann et al., Mol Cell Proteomics, 3(3):226-37 (2004); Liu et al., Biotechniques. 32(4):898, 900, 902 passim (2002)).


Using this approach, several interactions were identified which have important significance as to how DCR-1 can be up- or down-regulated and how DCR-1 is implicated in different functions. Table 1 lists the DCR-1 interactors identified using the above approach. Table 2 shows the corresponding protein interaction data obtained for each interactor. Many of these interactors are widely conserved and have homologs in other species such as human or mouse. These interactors are implicated as activators or inhibitors of the DCR-1 activity, specificity, and/or stability and can be utilized for improved in vitro processing of a variety of DCR-1 proteins. The interactors can also be used as part of a rationale or also as targets for pharmaceutical intervention in order to modulate the properties of DCR-1 in vivo.

EXAMPLE 2
Methods for Conducting a Whole Organism Search for Dicer Interactions

In order to identify Dicer interacting proteins in a whole organism, strategies to affinity-purify Dicer (DCR-1) by multiple independent matrixes, both from embryos and gravid adults C. elegans, were developed. Fractionation analysis showed that most, if not all the C. elegans Dicer protein can be found in the S100 fraction (FIG. 2).


For the adult purification, rabbit polyclonal sera having efficient immunoprecipitation capacity for the Dicer protein were identified. The antisera were affinity-purified against their respective antigen, coupled covalently to agarose matrixes, and used for batch immuno-affinity purifications. Controls included preparations from extracts genetically null for any Dicer expression (dcr-1 deletion allele (ok247)), or mock purification comprising neutralized affinity beads.


For the embryonic purifications, a transgenic dcr-1::8×HA genomic fusion driven by its own promoter, was used. The transgene allowed the sterility phenotype of dcr-1−/− to be rescued, and a robust expression in young embryos indicating it can support the functions of DCR-1 in the germline. Purification of DCR-1::8×HA fusion protein was carried out using two distinct monoclonal HA-directed affinity matrixes, and used the non-transgenic WT (N2) embryos as a control.


The purified proteins were eluted and analyzed using the Multi-Dimensional Protein Identification Technology (MudPIT). Interacting proteins were identified by comparison of the detected peptides with both the predicted and confirmed ORF library of the C. elegans genome. Protein candidates were not investigated further if they were also found in the depleted control, or in the mock purification (uncoupled matrix only). Chaperones, and two structural proteins, which were found in multiple non-related purifications, and known to be common non-specific interactions, were intentionally excluded. A high confidence set of interactions for proteins that could be detected in multiple purifications, with at least two independent matrixes, was defined. Using this strategy, 16 proteins were shown to interact with DCR-1. Table 3 depicts the interactions that were detected using this criteria.

rde: required for RNAi;

eri: enhancer of RNAi;

*weak peptide coverage only,

**due to the robust interaction, weak peptide coverage of RDE-4 is also detected in the dcr counterselected allele, likely due to interaction with the maternal load.


Proteins known to be involved in the initiation step of RNAi were found in all the DCR-1 purifications. The double-stranded binding protein RDE-4 was shown to interact with DCR-1. RDE-4 was also shown to interact with the argonaute family protein RDE-1, and the helicase DRH. In addition, RDE-4, DRH-1 and DRH-2 proteins were detected as interactors when pulling down with DCR-1.


In addition to the proteins involved in initiation of RNAi, other proteins having characterized functions that relate to small RNAs, were detected. Two argonaute proteins, ALG-1 and ALG-2, were also detected in the adult DCR-1 purifications. These paralog proteins are required for the efficient processing of a variety of miRNA precursors, but were heretofore unknown to interact physically with DCR-1.


Interactions with the rdrp RRF-3, and the SAP domain ERI-1 nuclease were also detected in the embryonic purifications. Interestingly when the genes coding for these proteins were inactivated, an enhancement of the classical RNAi response is observed (eri phenotype) indicating that rrf-3 and eri-1 encode negative regulators of RNAi.


In addition, the protein D2005.5 was detected which did not have a characterized small RNA-related function, but is a paralog of the dicer-related helicases drh-1 and drh-2.


For eight other proteins, no previous link with DCR-1 functions, or with small RNA-mediated silencing was known. Four detected proteins have known functions: snRNP core protein D1 (SNR-3), the translation elongation factor 2 (EFT-2), the NHL family ring finger-B box-Coiled coil translational repressor LIN-41, and subunit TAF6 of the transcription initiation factor TFIID (TAF-6.1). Finally four others have unknown functions. This subgroup includes T23G7.1 (an ortholog of the mammalian PIR1), the novel proteins C32A3.2, W09B6.3 (expressed as an operon with TAF-6.1), and the TUDOR domain protein Y38F2AR.1 (FIG. 3)


EXAMPLE 3
Methods for Determining In Vivo Activity of Dicer Interacting Proteins

To address the possible functions of these proteins in DCR-1-related mechanisms, the phenotypes of the rnai knock down for their corresponding genes (Table 3) was examined. The genes snr-3 and eft-2 (rnai) demonstrate pleiotropic phenotypes and growth defects. For the remaining Dicer interacting proteins, deletion alleles for d2005.5 (tm1217), t23g7.5 (tm1496), c32a3.2(tm1314), w09b6.3(tm1361) and y38j2ar.1(tm1705) were generated.


In addition, because two interacting protein were encoded by eri genes, the location of the genes encoding the interacting proteins with the mapping intervals of alleles generated in a screen for mutants that increase sensitivity of a neuronal gfp reporter to gfp rnai, were generated. Using this strategy three genes, TAF-6.1, w09b6.3 (part of a common operon), and y38f2ar.1 were mapped within the intervals of the eri-3 and eri-5 mutations, respectively. These three gene sequences were found to comprise nonsense point mutations. In addition, another enhancer (eri-4 (mg375)) mapped in proximity to DCR-1, and a point mutation (glycine 351 to arginine) was discovered in the C-terminus extremity of the conserved C-terminus sub-domain of its helicase domain.


EXAMPLE 3
Methods for Determining the In Vivo RNAi Activity of Dicer Interacting Proteins

The potency of the RNAi activity in whole animals, either for enhancement or deficiency (Table 2), was examined. First, their response in a high sensitivity unc-22 (rnai) somatic (Po) assay, was determined. This assay revealed that the interactor T23G7.5 allele exhibited a drastically reduced sensitivity to rnai when assayed in the soma, both for endogenous unc-22 (rnai) silencing and for gfp (rnai) silencing of a transgenic reporter. Possibly due to the maternal load the effect on RNAi was important, but partial. The mutant on itself also presents developmental defects: the homozygous null grows normally and suddenly arrests at the L4 stage, never reaching adulthood. A generalized loss of gene expression could not be responsible for the lack of RNAi response, as the arrested animals could still transcribe and translate a reporter de novo to a WT level. This protein encodes a conserved RNA phosphatase with homology to a family of capping enzymes, and associates with RNP particles in mammalian culture cells. Its enzymatic activity was shown to have specificity toward the removal of the β- and γ-phosphate residues on the 5′ end of triphosphate RNA substrates. This interaction was consistently detected both in the adult and embryonic purifications of DCR-1, and indicating its role in RNAi mechanisms. Thus, T23G7.5 was determined to be essential for development and RNAi


EXAMPLE 4
Methods for Determining the In Vivo RNAi Enhancer Activity of Dicer Interacting Proteins

The Dicer interacting proteins, w09b6.3 and y38f2ar.1 were determined enhancers of RNAi. Briefly, mutants using rnai targets, which do not exhibit a phenotype, or exhibit a very low penetrance in the WT (N2) genetic background, were assayed to test the possibility that these genes encode enhancers of rnai (eri). As observed, unc-73 (rnai) does not usually exhibit a strong penetrance when wt (N2) animals are exposed (4+−4%). As previously observed, eri-1(mg366) and rrf-3(pk1426) gave a very penetrant effect when exposed to unc-73 E. coli feeding strain (98+−2%). Similarly, a drastically higher penetrance was observed in the w09b6.3 (tm1361), y38f2ar.1 (mg392), and DCR-1(mg375) alleles (100%, 82.5+−11%, and 100%, respectively). Injection assays for lin-1 (rnai), and feeding assays for dpy-13 (rnai), hmr-1(mai), or gfp(mai) also supported these observations (not shown). Thus, it was concluded that the w09b6.3, and y38f2ar.1 mutations are enhancers of rnai (eri).


EXAMPLE 5
Methods for Determining the In Vivo Developmental Effects of Dicer Interacting Proteins

The Dicer interacting proteins eri-3, eri-4 and eri-5 were determined to have similar developmental defects. In addition to the similar effect on rnai, the rrf-3 and eri-1 genes were previously shown to have indistinguishable developmental defects and to act in the same genetic pathway. Known developmental defects include a strong sterility phenotype at 25° C., which is rescued at 15° C., or by crossing with WT males, suggestive of sperm defects. Mutant animals also exhibit spontaneous silencing of some simple transgenic arrays in the soma and a low incidence of X chromosome non-disjunction, visible by a High Incidence of Males (HIM) phenotype.


To test the idea that eri-3, eri-4 and eri-5 were acting on the same developmental mechanism, the defects associated with their corresponding alleles, were examined. Akin to alleles of rrf-3 and eri-1, mutations in these two genes led to mean brood sizes of 0±1 for w09b6.3 and of 1±1 for y38f2ar.1 −/− animals at 25° C. In contrast, at 15° C. the same alleles gave mean brood sizes of 155±12 for w09b6.3 and 167±20 for y38f2ar.1. Interest what was observed for rrf-3 and eri-1 alleles, the temperature sensitive sterility phenotype of w09b6.3 and y38f2ar.1 can be rescued by crossing with wt males, and therefore believed to be defective in sperm function. Additionally, a 3 to 5 fold increase in incidence of males was also observed in the corresponding mutants, compared to the WT(N2) spontaneous incidence (˜0.1%). Altogether, the unique, and specific combination of defects observed in the eri-3, eri-4 and eri-5 mutants indicates their involvement in a common pathway with eri-1 and rrf-3 (FIG. 4)


EXAMPLE 6
Methods for Determining the In Vivo Helicase/Chromosomal Effects of Dicer Interacting Proteins

The Dicer interacting protein DRH-3, when depleted, was determined to cause sterility and chromosome segregation defects. Mutations in the gene encoding the DCR-1-interacting protein D2005.5 also led to dramatic fertility defects. Because it encodes a paralog of the DEAX/D box helicase drh-1 and drh-2, this Dicer interacting protein was renamed drh-3. In contrast, despite the close homology, drh-3 is not required for initiation of the classical RNAi pathway, at least in the soma where it could be examined (see Table 3). Instead, while the drh-3(tm1217) allele animals were sterile as homozygous and examination of a pie-1::his-3::gfp transgenic strain revealed abnormally shaped oocytes with proximal mitosis, and occasional occurrence of multinucleation, rnai depletion led to a slow onset, but penetrant early embryonic arrest (Table 3). Although the terminal phenotype of this arrest was variable, the observed embryonic arrest was progressively earlier in embryos laid in periods extending two or three days after the adult injection. Interestingly and consistently with the phenotype exhibited in the deletion mutant, earlier injection of Po animals (L3 or L4 animals) also led to sterility. The earliest defects in the affected embryos using time-lapse videomicroscopy were also characterized. As observed, the first cell division was abnormal, and chromosomes lagging on the mitotic spindle could be observed at metaphase. Chromosome segregation later resulted in abnormally shaped nuclei.


Thus, it was noted that this initial developmental defect resembled the observed defects described in S. pombe for mutants in the RNAi machinery.

Methods for Determining the In Vivo Effects of Dicer Interacting Proteins on the Accumulation of Endogenous Small RNAs

The Dicer interacting protein drh-3 and the eri are required for the accumulation of classes of endogenous small RNAs.


Because divergent phenotypes were observed in many genes encoding the different DCR-1 interacting proteins, different phenotypic groups would be reflected by defects in accumulation and/or processing of different classes of small RNA. To test this hypothesis, the status of 5 classes of small RNAs known to require dcr-1 for efficient production, in the mutants generated, was examined. Sensitivity to exogenous dsRNA-triggering was used as a functional output for involvement in the classical RNAi pathway. Also examined, was the processing of miRNA precursors, the accumulation of the tncR, and small RNA-derived from an X chromosome-derived contig. Finally, accumulation of endogenous siRNAs (endo siRNAs) for a variety of loci previously shown to naturally produce these small RNAs, was examined


Because dcr-1 −/−, and drh-3−/− are sterile, a counter-selectable balancer strategy to select for nulls within large populations of animals, was employed. The maternal load of the two gene products was sufficient to lead the animals through early development and sterile adults could be studied. To look for an alg-1/alg-2 depletion effect on small RNAs, animals depleted of alg-1 by rnai in an alg-2−/− (ok304) animal background, were used.


A variety of miRNA were examined and no defects in the mature form accumulation nor in precursor processing was observed in the rde-4, the eri, nor in the drh-3 mutants. In contrast, a moderate to strong miRNA precursor accumulation was visible in alg-1/2, and dcr-1 depleted animals. These results indicate that these two proteins are crucial to most, if not all the miRNA maturation. However, the effect observed here on the precursor accumulation depends on the timing of the miRNA transcription and export relative to the depletion of ALG-1 protein by RNAi or the turnover of the maternal load of DCR-1 in the counterseleted F1 nulls.


Examination of the small RNA populations in the drh-3 counter-selectable nulls revealed that, while this protein is dispensable for normal accumulation of miRNAs, X-derived small RNAs, or the examined tncRs, it is required for the accumulation of all the examined ORF-derived endo-siRNA. Acting as controls, alg-depleted animals, and another counterselectable sterile mutant j20d12.1 did not show such defects in accumulation of these small RNAs. While most of the endo-siRNAs detected were only detected in the germline, drh-3 was also required for the production of soma-derived endo-siRNA k02e2.6. This result implicates the DCR-1-interacting protein DRH-3 specifically in the production and/or stabilization of a broad range of the ORF-derived endogenous-siRNAs.


The five eri mutants exhibited very consistent molecular defects in the accumulation of the mature small RNAs. While they enhanced the classical RNAi response (when triggered from exogenous sources of dsRNA), their mutation prevented accumulation of the examined tncR, and of the X locus-derived small RNAs. Interestingly, rde-4 was also required for the accumulation of the X locus-derived small RNAs, but dispensable for the tncRs or the ORF-derived endo-siRNAs, showing the modulatory nature of the contribution of the DCR-1 interactors for production of diverse small RNA classes.


The eri mutations did not affect the accumulation of most of the endo-siRNAs. However, surprisingly, the eri mutants also failed to accumulate endo-siRNAs from a very restricted number of genes. Interestingly, the eri genes also exhibited this defect at the permissive temperature in gravid adults, showing that the developmental process involving the eri genes, and not their function in endo-siRNAs accumulation is a temperature-sensitive process. This observation, and the presence of these endo-siRNAs in germline-less animals (FIG. 6, bn2(glp-4)) rules out the idea that the eri genes fail to show these endo-siRNAs because they lack the tissue where they are produced.


These results support the idea that different combinations of DCR-1-interacting proteins are required for efficient accumulation of distinct classes of endogenous small RNAs. These results support a function for the DCR-1-interacting ERI proteins in the initiation of a variety of distinct endogenous small RNA-mediated silencing mechanisms (FIG. 6).
