Markers for peroxisomal proliferators

FIELD OF THE INVENTION
The present invention relates to a composition for use in detecting toxicological effects of test compounds or therapeutic treatments and methods employing such compositions.
BACKGROUND OF THE INVENTION
Toxicity testing is a necessary and time-consuming part of the pharmaceutical drug development pipeline. A more rapid screen to detect toxicity of lead drug candidates may be the use of gene expression microarrays. For example, microarrays consisting of full length genes or gene fragments on a substrate may be formed. These arrays can then be tested with samples treated with the drug candidates to elucidate the gene expression pattern associated with treatment with the drug candidate. This gene pattern can be compared with gene expression patterns of compounds associated with known toxicological responses.
Benzo(a)pyrene is a known rodent and likely human carcinogen and is the prototype of a class of compounds, the polycyclic aromatic hydrocarbons. It is metabolized by several forms of cytochrome P450 and associated enzymes to both activated and detoxified metabolites (Dogawa et al (1994) Cancer Res. 54: 4915-4919). The ultimate metabolites are the bay-region diol epoxide, benzo(a)pyrene-7,8-diol-9,10-epoxide (BPDE) and the K-region diol epoxide, 9-hydroxy benzo(a)pyrene-4,5-oxide, which have been shown to cause DNA adduct formation (alkylation of guanine bases). DNA adducts have been shown to persist in rat liver up to 56 days following treatment with benzo(a)pyrene at a dose of 10 mg/kg body weight 3 times per week for 2 weeks (Qu and Stacey, (1996) Carcinogenesis 17: 53-59).
Acetaminophen is a widely-used analgesic. It is metabolized by specific cytochrome P450 isozymes with the majority of the drug undergoing detoxification by glucuronic acid, sulfate and glutathione conjugation pathways (Chen. et al. (1998) Chem. Res. Toxicol. 11: 295-301). However, at high nontherapeutic doses, acetaminophen can cause hepatic and renal failure by being metabolized to an active intermediate, N-acetyl-p-benzoquinone imine (NAPQI). NAPQI then binds to sulfhydryl groups of proteins causing their inactivation and leading to subsequent cell death (Kroger et al. Gen. Pharmacol. (1997) 28: 257-263).
Clofibrate is an antilipidemic drug which lowers elevated levels of serum triglycerides. In rodents, chronic treatment produces hepatomegaly, an increase in hepatic peroxisomes (Lock et al. (1989) Ann. Rev. Pharmacol. Toxicol. 29: 145-163). Clofibrate has been shown to increase levels of cytochrome P450 4A and reduce the levels of P450 4F (Kawashima et al. (1997) Arch. Biochem. Biophys. 347: 148-154). It is also involved in transcription of .beta.-oxidation genes as well as induction of peroxisome proliferator activated receptors (Arch. Biochem. Biophys. (1997) 347: 148-154).
The present invention provides compositions and methods for the screening, preferably in a microarray format, of compounds and therapeutic treatments for toxicological effects.
SUMMARY OF THE INVENTION
In one aspect, the invention provides a method for screening a compound for a toxicological effect. The method comprises selecting a plurality of polynucleotide targets, wherein the polynucleotide targets have first gene expression levels altered in tissues treated with known toxicological agents when compared with untreated tissues. Some of the first gene expression levels may be upregulated and others downregulated when associated with a toxicological response. A sample is treated with the compound to induce second gene expression levels of a plurality of polynucleotide probes. Then first and second gene expression levels are compared to identify those compounds that induce expression levels of the polynucleotide probes that are similar to those of the polynucleotide targets and the similarity of expression levels correlates with a toxicological effect of the compound.
Preferably, the comparing comprises (i) contacting the polynucleotide targets with the polynucleotide probes under conditions effective to form hybridization complexes between the polynucleotide targets and the polynucleotide probes; and (ii) detecting the presence or absence of the hybridization complexes. In this context, similarity may mean that at least 1, preferably at least 5, more preferably at least 10, of the upregulated polynucleotide targets form hybridization complexes with the polynucleotide probes at least once during a time course to a greater extent than would the probes derived from a sample not treated with the test compound or a known toxicological agent. Similarity may also mean that at least 1, preferably at least 3, of the downregulated polynucleotide target sequences form hybridization complexes with the polynucleotide probes at least once during a time course to a lesser extent than would the probes of a sample not treated with the test compound or a known toxicological agent.
Preferred tissues are selected from the group consisting of liver, kidney, brain, spleen, pancreas and lung. Preferred toxicological agents are selected from the group consisting of hypolipidemic drugs, n-alkylcarboxylic acids, n-alkylcarboxylic acid precursors, azole antifungal compounds, leukotriene D4 antagonists, herbicides, pesticides, phthalate esters, phenyl acetate, dehydroepiandrosterone sulfate, oleic acid, methanol and their corresponding metabolites. The polynucleotide targets comprise genes that are upregulated-or-down regulated at least 2.5 fold, preferably at least 3 fold, in tissues treated with known toxicological agents when compared with untreated tissues. Preferred polynucleotide targets are selected from the group consisting of SEQ ID NOs: 1-56, or fragments thereof, some of whose expression is upregulated and others of whose expression is downregulated. Even more preferable are SEQ ID NOs: 2, 3, 16, 18, 29, 43, 52, and 55 which are upregulated and SEQ ID NOs: 9, 10, 11, 12, 13, 14, 15, 22, 23, 30, 33, 35, 45, 47, 50, and 53 which are downregulated. In one embodiment, the polynucleotide targets are hybridizable array elements of a microarray.
Alternatively, the invention provides methods for screening a therapeutic treatment for a toxicological effect or for screening a sample for a toxicological response to a compound or therapeutic treatment.
In another aspect, the invention provides methods for preventing a toxicological response by administering complementary nucleotide sequences against one or more selected upregulated polynucleotide targets or a ribozyme that specifically cleaves such sequences. Alternatively, a toxicological response may be prevented by administering sense nucleotide sequences for one or more selected downregulated polynucleotide targets.
In yet another aspect, the invention provides methods for preventing a toxicological response by administering an agonist which initiates transcription of a gene comprising a downregulated polynucleotide of the invention. Alternatively, a toxicological response may be prevented by administering an antagonist which prevents transcription of a gene comprising an upregulated polynucleotide of the invention.

The Invention
The present invention provides a composition and method for screening test compounds or therapeutic treatments for toxicological effects. Additionally the invention provides methods for characterizing the toxicological responses of a sample to a test compound or a therapeutic treatment. In particular, the present invention provides a composition comprising a plurality of polynucleotide sequences derived from normal rat liver cDNA libraries, normalized rat liver cDNA libraries and prehybridized rat liver cDNA libraries and rat kidney libraries. The polynucleotide sequences have been further selected for exhibiting upregulated-or-downregulated gene expression in rat liver samples when the rat liver samples have been exposed to a known toxin, in particular a peroxisomal proliferator (PP). PPs include hypolipidemic drugs, such as clofibrate, clofenic acid, nafenopin, gemfibrozil, ciprofibrate, fenofibrate, bezafibrate, halofenate, simfibrate, benzofibrate, etofibrate, WY-14,643, and the like; nalkylcarboxylic acids, such as trichloroacetic acid, valproic acid, hexanoic acid, and the like; n-alkylcarboxylic acid precursors, such as trichloroethylene, etrachloroethylene, and the like; azole antifungal compounds, such as bifenazole, and the like; leukotriene D4 antagonists; herbicides; pesticides; phthalate esters, such as di-[2-ethylhexyl] phthalate, mono-[2-ethylhexyl] phthalate, and the like; and natural chemicals, such as phenyl acetate, dehydroepiandrosterone sulfate, oleic acid, methanol, and the like. In a preferred embodiment the toxin is clofibrate, or one of its toxic metabolites. The extent of upregulation or downregulation is at least 2.5 fold, more preferably at least 3 fold.
Exemplary polynucleotide sequences (targets) include SEQ ID NOs: 1-56 provided in the Sequence Listing or fragments thereof. These and other polynucleotide sequences can be immobilized on a substrate and used as hybridizable array elements in a microarray format. The microarray may be used to characterize gene expression patterns associated with novel compounds to elucidate any toxicological effects or to monitor the effects of therapeutic treatments where toxicological effects may be expected.
When the polynucleotide targets are employed as hybridizable array elements in a microarray, the array elements are organized in an ordered fashion so that each element is present at a specified location on the substrate. Because the array elements are at specified locations on the substrate, the hybridization patterns and intensities (which together create a unique expression profile) can be interpreted in terms of expression levels of particular genes and can be correlated with a toxicological effect associated with a compound or a therapeutic treatment.
Furthermore, the present invention provides methods for screening compounds and/or therapeutic treatments for potential toxicological effects and for screening a sample's toxicological response to a particular test compound. Briefly, these methods entail treating a sample with the compound to be tested to elicit a change in gene expression patterns comprising the expression of a plurality of polynucleotide probes. Polynucleotide targets are selected by identifying those genes in rat liver or kidney that are upregulated-or-downregulated at least 2.5 fold, more preferably at least 3 fold, when treated with a known toxic compound. Then, the polynucleotide targets and probes are combined under conditions effective to form hybridization complexes which may be detected by methods well known in the art. Detection of higher or lower levels of such hybridization complexes compared with hybridization complexes derived from samples treated with a compound that is known not to induce a toxicological effect correlates with a toxicological effect of a test compound or a toxicological response to a therapeutic treatment.
Sequences are identified that reflect all or most of the genes that are expressed in rat liver or kidney. Sequences may be identified by isolating clones derived from several types of rat cDNA libraries, including normal rat cDNA libraries, normalized rat cDNA libraries and prehybridized rat cDNA libraries. Clone inserts derived from these clones may be partially sequenced to generate expressed sequence tags (ESTs).
In one embodiment, two collections of ESTs are identified and sequenced. A first collection of ESTs (the originator sequences) are derived from rat liver and kidney and are derived from the cDNA libraries presented in the Examples. A second collection includes ESTs derived from other rat cDNA libraries available in the ZooSeq database (Incyte Pharmaceuticals).
The two collections of ESTs are screened electronically to form master clusters of ESTs. Master clusters are formed by identifying overlapping EST sequences and assembling these ESTs. A nucleic acid fragment assembly tool, such as the Phrap tool (WashU-Merck) and the GELVIEW Fragment Assembly system (GCG), can be used for this purpose. The minimum number of clones necessary to constitute a cluster is two. In another embodiment, a collection of human genes implicated in toxicology are used as the originator sequences and the collect-on of ESTs derived from the 55 rat cDNA libraries are again used as the additional sequences. Master clusters are formed around specific originator sequences, including the ESTs identified in rat liver and kidney or GenBank sequences which code for polypeptides implicated in toxicology in humans.
After the sequences have been clustered, the most 5' clone is selected. After assembling the sequences, a representative clone is nominated from each master cluster. The most 5' clone is usually preferred because it is the one most likely to contain the complete gene. The nomination process is described in greater detail in "Relational Database and System for Storing Information Relating to Biomolecular Sequences and Reagents, Ser. No. 09/034,807, filed Mar. 4, 1998, herein incorporated in its entirety by reference. These sequences may be used as array elements on a microarray.
Then, samples are treated, preferably at subchronic doses, with one or more known toxicological agents over a defined time course. Preferably, the agents are peroxisomal proliferators.
The gene expression patterns derived from such treated biological samples can be compared with the gene expression patterns derived from untreated biological samples to identify genes whose expression is either upregulated or downregulated due to the presence of the toxins. These sequences may then be employed as array elements in a microarray alone or in combination with other array element sequences. Such a microarray is particularly useful to detect and characterize gene expression patterns associated with known toxicological agents. Such gene expression patterns can then be used for comparison to identify other compounds or therapeutic treatments which also elicit a toxicological response.
The selected polynucleotide sequences can be manipulated further to optimize the performance of the polynucleotide sequences as hybridization sequences. Some sequences may not hybridize effectively under hybridization conditions due to secondary structure. To optimize probe hybridization, the probe sequences are examined using a computer algorithm to identify portions of genes without potential secondary structure. Such computer algorithms are well known in the art, such as OLIGO 4.06 Primer Analysis Software (National Biosciences) or LASERGENE software (DNASTAR). These programs can search nucleotide sequences to identify stem loop structures and tandem repeats and to analyze G+C content of the sequence (those sequences with a G+C content greater than 60% are excluded). Alternatively, the sequences can be optimized by trial and error. Experiments can be performed to determine whether sequences and complementary target polynucleotides hybridize optimally under experimental conditions.
The polynucleotide sequences can be any RNA-like or DNA-like material, such as mRNAs, cDNAs, genomic DNA, peptide nucleic acids, branched DNAs and the like. The polynucleotide sequences can be in sense or antisense orientations.
In one embodiment, the polynucleotide sequences are cDNAs. The size of the DNA sequence of interest may vary, and is preferably from 50 to 10,000 nucleotides, more preferably from 150 to 3,500 nucleotides. In a second embodiment, the polynucleotide sequences are vector DNAs. In this case the size of the DNA sequence of interest, i.e., the insert sequence, may vary from about 50 to 10,000 nucleotides, more preferably from about 150 to 3,500 nucleotides.
The polynucleotide sequences can be prepared by a variety of synthetic or enzymatic schemes which are well known in the art. (Caruthers et al. (1980) Nucleic Acids Symp. Ser. (7): 215-223). Nucleotide analogues can be incorporated into the polynucleotide sequences by methods well known in the art. The only requirement is that the incorporated nucleotide analogues must serve to base pair with polynucleotide probe sequences. For example, certain guanine nucleotides can be substituted with hypoxanthine which base pairs with cytosine residues. However, these base pairs are less stable than those between guanine and cytosine. Alternatively, adenine nucleotides can be substituted with 2,6-diaminopurine which can form stronger base pairs than those between adenine and thymidine. Additionally, the polynucleotide sequences can include nucleotides that have been derivatized chemically or enzymatically. Typical modifications include derivatization with acyl, alkyl, aryl or amino groups.
The polynucleotide sequences can be immobilized on a substrate via chemical bonding. Furthermore, the sequences do not have to be directly bound to the substrate, but rather can be bound to the substrate through a linker group. The linker groups are typically about 6 to 50 atoms long to provide exposure to the attached polynucleotide probe. Preferred linker groups include (ethylene glycol oligomers, diamines, diacids and the like. Reactive groups on the substrate surface react with one of the terminal portions of the linker to bind the linker to the substrate. The other terminal portion of the linker is then functionalized for binding the polynucleotide probe. Preferred substrates are any suitable rigid or semirigid support, including membranes, filters, chips, slides, wafers, fibers, magnetic or nonmagnetic beads, gels, tubing, plates, polymers, microparticles and capillaries. The substrate can have a variety of surface forms, such as wells, trenches, pins, channels and pores, to which the polynucleotide sequences are bound. Preferably, the substrates are optically transparent.
The samples can be any sample comprising polynucleotide probes and obtained from any bodily fluid (blood, urine, saliva, phlegm, gastric juices, etc.), cultured cells, biopsies, or other tissue preparations. The samples can be derived from humans or animal models.
DNA or RNA can be isolated from the sample according to any of a number of methods well known to those of skill in the art. For example, methods of purification of nucleic acids are described in Laboratory Techniques in Biochemistry and Molecular Biology: Hybridization With Nucleic Acid Probes, Part I. Theory and Nucleic Acid Preparation, P. Tijssen, ed. Elsevier (1993). In one preferred embodiment, total RNA is isolated using the TRIZOL total RNA isolation reagent (Life Technologies, Inc.) and mRNA is isolated using oligo d(T) column chromatography or glass beads. When polynucleotide probes are amplified it is desirable to amplify the nucleic acid sample and maintain the relative abundances of the original sample, including low abundance transcripts. RNA can be amplified in vitro, in situ or in vivo (See Eberwine U.S. Pat. No. 5,514,545).
It is also advantageous to include quantitation controls within the sample to assure that amplification and labeling procedures do not change the true distribution of polynucleotide probes in a sample. For this purpose, a sample is spiked with a known amount of a control polynucleotide and the composition of polynucleotide sequences includes reference polynucleotide sequences which specifically hybridize with the control target polynucleotides. After hybridization and processing, the hybridization signals obtained should reflect accurately the amounts of control polynucleotide added to the sample.
Prior to hybridization, it may be desirable to fragment the polynucleotide probes. Fragmentation improves hybridization by minimizing secondary structure and cross-hybridization to other polynucleotide probes in the sample or noncomplementary polynucleotide sequences. Fragmentation can be performed by mechanical or chemical means.
The polynucleotide probes may be labeled with one or more labeling moieties to allow for detection of hybridized probe/target polynucleotide complexes. The labeling moieties can include compositions that can be detected by spectroscopic, photochemical, biochemical, bioelectronic, immunochemical, electrical, optical or chemical means. The labeling moieties include radioisotopes, such as .sup.32 P, .sup.33 P or .sup.35 S, chemiluminescent compounds, labeled binding proteins, heavy metal atoms, spectroscopic markers, such as fluorescent markers and dyes, magnetic labels, linked enzymes, mass spectrometry tags, spin labels, electron transfer donors and acceptors, and the like. Preferred fluorescent markers include Cy3 and Cy5 (Amersham Pharmacia Biotech).
Hybridization causes a polynucleotide probe and a complementary target polynucleotide to form a stable duplex through base pairing. Hybridization methods are well known to those skilled in the art (See, for example, Laboratory Techniques in Biochemistry and Molecular Biology, Vol. 24: Hybridization With Nucleic Acid Probes, P. Tijssen, ed. Elsevier, N.Y. (1993)). Conditions can be selected for hybridization where only fully complementary target and polynucleotide probe hybridize, i.e., each base pair must interact with its complementary base pair. Alternatively, conditions can be selected where target and polynucleotide sequences have mismatches but are still able to hybridize. Suitable conditions can be defined by salt concentration, temperature, and other chemicals and conditions well known in the art. Varying additional parameters, such as hybridization time, the concentration of detergent or solvent, and the inclusion or exclusion of carrier DNA, are well known to those skilled in the art. Salt concentration may be less than about 750 mM NaCl and 75 mM trisodium citrate, preferably less than about 500 mM NaCl and 50 mM trisodium citrate, and most preferably less than about 250 mM NaCl and 25 mM trisodium citrate. Stringent temperature conditions will ordinarily include temperatures of at least about 22.degree. C., more preferably of at least about 37.degree. C., and most preferably of at least about 42.degree. C. Additional variations on these conditions will be readily apparent to those skilled in the art (Wahl, G. M. and S. L. Berger (1987) Methods Enzymol. 152: 399-407; Kimmel, A. R. (1987) Methods Enzymol. 152: 507-511; Ausubel, F. M. et al. (1997) Short Protocols in Molecular Biology, John Wiley & Sons, New York, N.Y.; and Sambrook, J. et al. (1989) Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Press, Plainview, N.Y.).
More particularly, hybridization can be performed with buffers, such as 5.times. SCC/0.1% SDS at 60.degree. C. for about 6 hours. Subsequent washes are performed at higher stringency with buffers, such as 1.times. SCC/0.1% SDS at 45.degree. C., then 0.1.times. SCC at 45.degree. C. to retain hybridization of only those target/probe complexes that contain exactly complementary sequences.
Hybridization specificity can be evaluated by comparing the hybridization of specificity-control polynucleotide sequences to specificity-control polynucleotide probes that are added to a sample in a known amount. The specificity-control target polynucleotides may have one or more sequence mismatches compared with the corresponding polynucleotide sequences. In this manner, whether only complementary target polynucleotides are hybridizing to the polynucleotide sequences or whether mismatched hybrid duplexes are forming is determined.
Hybridization reactions can be performed in absolute or differential hybridization formats. In the absolute hybridization format, polynucleotide probes from one sample are hybridized to the sequences in a microarray format and signals detected after hybridization complex formation correlate to polynucleotide probe levels in a sample. In the differential hybridization format, the differential expression of a set of genes in two biological samples is analyzed. For differential hybridization, polynucleotide probes from both biological samples are prepared and labeled with different labeling moieties. A mixture of the two labeled polynucleotide probes is added to a microarray. The microarray is then examined under conditions in which the emissions from the two different labels are individually detectable. Sequences in the microarray that are hybridized to substantially equal numbers of polynucleotide probes derived from both biological samples give a distinct combined fluorescence (Shalon et al. PCT publication WO95/35505). In a preferred embodiment, the labels are fluorescent labels with distinguishable emission spectra, such as Cy3 and Cy5 fluorophores.
After hybridization, the microarray is washed to remove nonhybridized nucleic acids and complex formation between the hybridizable array elements and the polynucleotide probes is detected. Methods for detecting complex formation are well known to those skilled in the art. In a preferred embodiment, the polynucleotide probes are labeled with a fluorescent label and measurement of levels and patterns of fluorescence indicative of complex formation is accomplished by fluorescence microscopy, preferably confocal fluorescence microscopy.
In a differential hybridization experiment, polynucleotide probes from two or more different biological samples are labeled with two or more different fluorescent labels with different emission wavelengths. Fluorescent signals are detected separately with different photomultipliers set to detect specific wavelengths. The relative abundances/expression levels of the polynucleotide probes in two or more samples is obtained.
Typically, microarray fluorescence intensities can be normalized to take into account variations in hybridization intensities when more than one microarray is used under similar test conditions. In a preferred embodiment, individual polynucleotide probe/target complex hybridization intensities are normalized using the intensities derived from internal normalization controls contained on each microarray.
The composition comprising a plurality of polynucleotide target sequences can be used as hybridizable elements in a microarray. Such a microarray can be employed to identify expression profiles associated with particular toxicological responses. Then, a particular subset of these polynucleotide targets can be identified whose expression is altered in response to a particular toxicological agent. These polynucleotides can be employed to identify other compounds with a similar toxicological response.
Alternatively, for some treatments with known side effects, the microarray, and expression patterns derived therefrom, is employed to "fine tune" the treatment regimen. A dosage is established that minimizes expression patterns associated with undesirable side effects. This approach may be more sensitive and rapid than waiting for the patient to show toxicological side effects before altering the course of treatment.
Generally, the method for screening a compound or therapeutic treatment to identify those with a potential toxicological effect entails selecting a plurality of polynucleotide targets genes whose gene expression levels are altered in tissues treated with known toxicological agents when compared with untreated tissues. Then a sample is treated with the compound or therapeutic treatment to induce a pattern of gene expression comprising the expression of a plurality of polynucleotide probes. A test compound may be screened at several doses to determine doses which may be toxic and other doses that may not.
Then, the expression levels of the polynucleotide targets and the polynucleotide probes are compared to identify those compounds that induce expression levels of the polynucleotide probes that are similar to those of the polynucleotide targets. In one preferred embodiment, gene expression levels are compared by contacting the polynucleotide targets with the polynucleotide probes under conditions effective to form hybridization complexes between polynucleotide targets and polynucleotide probes; and detecting the presence or absence of the hybridization complexes.
Similarity may mean that at least 1, preferably at least 5, more preferably at least 10, of the upregulated polynucleotide targets form hybridization complexes with the polynucleotide probes at least once during a time course to a greater extent than would the probes of a sample not treated with the test compound. Similarity may also mean that at least 1, preferably at least 3, of the downregulated polynucleotide target sequences form hybridization complexes with the polynucleotide probes at least once during a time course to a lesser extent than would the probes of a sample not treated with the test compound.
Such a similarity of expression patterns means that a toxicological effect is associated with the compound or therapeutic treatment tested. Preferably, the toxicological agents belong to the class of peroxisomal proliferators, including hypolipidemic drugs, such as clofibrate, clofenic acid, nafenopin, gemfibrozil, ciprofibrate, fenofibrate, bezafibrate, halofenate, simfibrate, benzofibrate, etofibrate, WY-14,643, and the like; n-alkylcarboxylic acids, such as trichloroacetic acid, valproic acid, hexanoic acid, and the like; n-alkylcarboxylic acid precursors, such as trichloroethylene, etrachloroethylene, and the like; azole antifungal compounds, such as bifenazole, and the like; leukotriene D4 antagonists; herbicides; pesticides; phthalate esters, such as di-[2-othylhexyl] phthalate, mono-[2-ethylhexyl] phthalate, and the like; and natural chemicals, such as phenyl acetate, dehydroepiandrosterone sulfate, oleic acid, methanol, and the like. Of particular interest is the study of the toxic effects of these compounds on the liver, kidney, brain, spleen, pancreas and lung.
It is understood that this invention is not limited to the particular methodology, protocols, and reagents described, as these may vary. It is also understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention which will be limited only by the appended claims. The examples below are provided to illustrate the subject invention and are not included for the purpose of limiting the invention.
I cDNA Library Construction
The RALINOT01 library was constructed from liver tissue removed from a pool of fifty 10- to 11-week-old Sprague-Dawley female rats (Charles River Laboratories, Wilmington, Mass.). The animals were housed in standard laboratory caging and fed PMI-certified Rodent Diet #5002. The animals appeared to be in good health at the time of tissue harvest. The animals were anesthetized by CO.sub.2 induction, and then cardiocentesis was performed.
Frozen tissue was homogenized and lysed in TRIZOL reagent (1 g tissue/10 ml TRIZOL; Life Technologies, Inc), a monophasic solution of phenol and guanidine isothiocyanate, using a Brinkmann Homogenizer Polytron PT-3000 (Brinkmann Instruments, Westbury, N.Y.). After a brief incubation on ice, chloroform (1:5 v/v) was added and mixed, and then centrifuged at 1,000 rpm. The upper aqueous layer was removed to a fresh tube and the RNA precipitated with isopropanol, resuspended in DEPC-treated water, and treated with DNase for 25 min at 37.degree. C. The RNA was re-extracted once with phenol-chloroform, pH 4.7, and precipitated using 0.3 M sodium acetate and 2.5 volumes ethanol. The mRNA (poly(A+) RNA) was then isolated using an OLIGOTEX kit (QIAGEN, Inc., Chatsworth, Calif.) and used to construct the cDNA library.
The mRNA was handled according to the recommended protocols in the SuperScript Plasmid System for cDNA Synthesis and Plasmid Cloning (Gibco/BRL). The cDNAs were fractionated on a Sepharose CL4B column (Amersham Pharmacia Biotech), and those cDNAs exceeding 400 bp were ligated into the plasmid pINCY1 (Incyte Pharmaceuticals, Inc., Palo Alto, Calif.). The plasmid pINCY1 was subsequently transformed into DH5.alpha..TM. competent cells (Cat. #18258-012; Gibco/BRL).
The RAKINOT01 library was constructed using poly(A+) RNA isolated from kidney tissue removed from a pool of fifty, 7- to 8-week-old male Sprague-Dawley rats, as described above.
The PAKINOT02 library was constructed using poly(A+) RNA isolated from kidney tissue removed from a pool of fifty, 10- to 11-week-old female Sprague-Dawley rats, as described above.
II cDNA Library Normalization
In some cases, cDNA libraries were normalized in a single round according to the procedure of Soares et al. (1994, Proc. Natl. Acad. Sci. USA 91: 9228-9232) with the following modifications. The primer to template ratio in the primer extension reaction was increased from 2:1 to 10:1. The dNTP concentration in the reaction was reduced to 150 .mu.M each dNTP, allowing the generation of longer (400-10000 nt) primer extension products. The reannealing hybridization was extended from 13 to 19 hours. The single stranded DNA circles of the normalized library were purified by hydroxyapatite chromatography and converted to partially double-stranded by random priming, follower by electroporation into DH10B competent bacteria (Gibco/BRL).
The Soares normalization procedure is designed to reduce the initial variation in individual cDNA frequencies to achieve abundances within one order of magnitude while maintaining the overall sequence complexity of the library. In the normalization process, the prevalence of high-abundance cDNA clones decreases significantly, clones with mid-level abundance are relatively unaffected, and clones for rare transcripts are effectively increased in abundance. In the modified Soares normalization procedure, significantly longer hybridization times are used which allows for the increase of gene discovery rates by biasing the normalized libraries toward low-abundance cDNAs that are well represented in a standard transcript image.
The RALINON03 normalized rat liver library was constructed with 2.0.times.10.sup.6 independent clones from the RALINOT01 library. Starting RNA was made from liver tissue removed from a pool of fifty, 10- to 11-week-old female Sprague-Dawley rats. The library was normalized in one round using conditions adapted from Soares et al., supra, except that a significantly longer (48-hour) reannealing hybridization was used.
The PALINON04 normalized rat liver library was constructed with 4.6.times.10.sup.5 independent clones from the RALINOT01 library. Starting RNA was made from liver tissue removed from a pool of fifty, 10- to 11-week-old female Sprague-Dawley rats.
The RALINON07 normalized rat liver library was constructed with 2.0.times.10.sup.5 independent clones from the PALINOT01 library. Starting RNA was made from liver tissue removed from a pool of fifty, 10- to 11-week-old female Sprague-Dawley rats.
III cDNA Library Prehybridization
The RALINOH01 library was constructed with clones from the RALINOT01 library. Starting RNA was made from liver tissue removed from a pool of fifty, 10- to 11-week-old female Sprague-Dawley rats. After preparation of the cDNA library, 9,984 clones were spotted onto a nylon filter, incubated, and processed to bind plasmid DNA to the filter. 10 ml of pre-warmed hybridization buffer per were added. The filter was hybridized in 0.75 M NaCl, 0.1 M Na.sub.2 HPO.sub.4 /NaH.sub.2 PO.sub.4, 0.15 M Tris-HCl (pH 7.5), 5.times. Denhardt's Solution, 2% SDS, 100 .mu.g/ml sheared salmon sperm DNA, 50% formamide, and [.sup.32 P]-labeled oligonucleotide sequences made from RALINOT01, at 42.degree. C. for 14-16 hours. Then, filters were rinsed with 200 ml of 2.times. SSC at room temperature for 5 minutes. Filters were washed for 30 minutes at 68.degree. C. with 200 ml of pre-warmed wash 1 (2.times. SSC, 1% SDS). A second wash was performed for an additional 30 minutes at 68.degree. C. Filters were then washed twice with pre-warmed wash 2 (0.6.times. SSC, 1% SDS) for 30 minutes at 68.degree. C. 4,224 clones had very low hybridization signals and were selected for sequencing. About 20% of the clones do not have signals and these are isolated and sequenced.
IV Isolation and Sequencing of cDNA Clones
DNA was isolated using the following protocol. Single bacterial colonies were transferred into individual wells of 384-well plates (Genetix Ltd, Christchurch, UK) using sterile toothpicks. The wells contained 1 ml of sterile Terrific Broth (Catalog #22711, Life Technologies, Inc.) with 25 mg/l carbenicillin and 0.4% glycerol (v/v). The plates were covered and placed in a Thermodyne incubator (Newtown Square, Pa.) at 37.degree. C. for 8-10 hours prior to use. Plasmid DNA was released from the cells and amplified using direct link PCR (RaD, V.B. (1994) Anal. Biochem. 216: 1-14) as follows. The direct link PCR solution included 30 ml of Nucleix Plus PCR nucleotide mix (Catalog #4577235, Amersham Pharmacia Biotech) and 300 .mu.l of Taq DNA polymerase (Catalog #0303Z, Amersham Pharmacia Biotech) with 12 .mu.l Pfu DNA polymerase (Stratagene). Five .mu.l of the PCR solution were added to each of the 384 wells using the MICROLAB 2200 system (Hamilton, Reno, Nev.); plates were centrifuged at 1000 rpm for 20 seconds and refrigerated until use. A 384 pin tool (V&P Scientific Inc, San Diego, Calif.) was used to transfer bacterial cells from the incubation plate into the plate containing the PCR solution where the component 0.1.degree. Tween 20 caused the cells to undergo lysis and release the plasmid DNA. After lysis, the plates were centrifuged up to 500 rpm, covered with a cycle sealer, and cycled using a 384-well Peltier Thermal Cycler (MJ PTC 200, MJ Research, Watertown, Mass.) using the program dPCR30 with the following parameters: Step 1) 95.degree. C., 1 minute; Step 2) 94.degree. C., 30 seconds; Step 3) 55.degree. C., 30 seconds; Step 4) 72.degree. C., 2 minutes; Step 5) steps 2, 3, and 4 repeated 29 times; Step 6) 72.degree. C., 10 minutes; and Step 7) storage at 4.degree. C.
The concentration of DNA in each well was determined by dispensing 100 .mu.l Pico Green Dye Mix (0.25% (v/v) Pico Green Dye) (Molecular Probes, Eugene, OR) dissolved in 1.times. TE and 0.5 .mu.l of undiluted PCR product into each well of an opaque fluorimeter plate (Corning Costar, Acton, Mass.), allowing the DNA to bind to Pico Green Dye. The plate was scanned in a Flouroscan II (Labsystems Oy, Helsinki, FI) to measure the fluorescence of the sample and to quantitate the concentration of DNA. Typical concentrations of each DNA sample were in the range of 100 to 500 ng/ml.
The cDNAs were sequenced by the method of Sanger, F. and A. R. Coulson (J. Mol. Biol. (1975) 94: 441-448), using either a HYDRA microdispenser (Robbins Scientific, Sunnyvale, Calif.) or MICROLAB 2200 (Hamilton) in combination with Peltier Thermal Cyclers (PTC200 from MJ Research, Watertown, Mass.) and ABI 377 DNA Sequencing Systems (Perkin Elmer). Most of the isolates were sequenced according to standard ABI protocols, using ABI kits (Cat. #79345, 79339, 79340, 79357, 79355). Typically, 500 to 700 base pairs were sequenced in 3.5 to 4 hours. The solution volumes were used at 0.25.times.-1.0.times. concentrations. In the alternative, cDNAs may have been sequenced using solutions and dyes from Amersham Pharmacia Biotech.
The sequences derived from the sequencing of the clone inserts were used to populate the Zooseq database (Incyte Pharmaceuticals, Inc.).
V Rat Liver and Kidney Gene Selection
As a first step, originator sequences from high throughput sequencing experiments were derived from clone inserts from RALINOT01, RAKINOT01, RAKINOT02, RALINOH01, RALINON03, RALINON04 and RALINON07. cDNA library clones were obtained. There were 18,140 rat liver sequences and 5,779 rat kidney sequences.
Additionally, 1,500 rat sequences derived from clone inserts of any of 55 rat cDNA libraries were selected based on their homology to genes coding for polypeptides implicated in toxicological responses including peroxisome-associated genes, lysosome-associated genes, apoptosis-associated genes, P450 cytochromes, sulfotransferases, cysteine proteases, and the like.
Then, all the remaining sequences derived from all of the rat cDNA library clones were clustered based on the originator sequences described above. The clustering process involved identifying overlapping sequences that have a match quality indicated by a product score of 50 using BLAST. 6581 master clusters were identified.
After forming the clone clusters, a consensus sequence was generated based on the assembly of the clone sequences using Phrap. The assembled sequences were then annotated by first screening the assembled sequences against GenBank using BLASTn and then by screening the assembled sequences against GenPept using FASTX. About two thirds of the assembled sequences were annotated, about one third of the assembled sequences were not annotated.
VI Microarray Preparation
Clones nominated in the process described in Example VI were used to generate array elements. Each array element was amplified from bacterial cells. PCR amplification used primers complementary to the vector sequences flanking the cDNA insert. Array elements were amplified in thirty cycles of PCR from an initial quantity of 1-2 ng to a final quantity greater than 5 .mu.g. Amplified array elements were then purified using Sephacryl-400 (Amersham Pharmacia Biotech, Piscataway, N.J.).
Purified array elements were immobilized on polymer-coated glass slides. Glass microscope slides (Corning, Corning, N.Y.) cleaned by ultrasound in 0.1% SDS and acetone, with extensive distilled water washes between and after treatments. Glass slides were etched in 4% hydrofluoric acid (VWR, West Chester, Pa.), washed extensively in distilled water, and coated with 0.05% aminopropyl silane (Sigma Aldrich, St. Louis, Mo.) in 95% ethanol. Coated slides were cured in a 110.degree. C. oven.
Array elements were applied to the coated glass substrate using a procedure described in U.S. Pat. No. 5,807,522 and incorporated herein by reference. In brief, 1 .mu.l of the array element DNA, at an average concentration of 0.5 .mu.g/ml in 3.times. SSC, was loaded into the open capillary printing element by a high-speed robotic apparatus. The apparatus then deposited about 5 nl of array element sample per slide. A total of 7404 array elements representing rat liver and kidney genes and a variety of control elements, including 14 synthetic control sequences, human genomic DNA, and yeast genomic DNA, were arrayed in four identical quadrants within a 1.8 cm.sup.2 area of the glass substrate.
Microarrays were UV-crosslinked using a STRATALINKER UV-crosslinker (Stratagene, La Jolla, Calif.). Microarrays were washed at room temperature once in 0.2, SDS and three times in distilled water. Non-specific binding sites were blocked by incubation of microarrays in 0.2% casein in phosphate buffered saline (PBS) (Tropix Inc., Bedford, Mass.) for 30 minutes at 60.degree. C. followed by washes in 0.2% SDS and distilled water as before.
VII Probe Preparation
Male Sprague-Dawley rats (6-8 wk old) were dosed intraperitoneally with either clofibrate (Acros, Geel, Belgium) at 250 mg/kg body weight (bw), or dimethylsulfoxide vehicle (DMSO; Acros) at less than 2 ml/kg bw. Animals were monitored daily for physical condition and body weight, and blood samples were assayed for serum alanine transferase (ALT) and aspartate aminotransferase (AST) levels using a diagnostic kit (Sigma Aldrich). Three animals per group were sacrificed approximately 12 hours (h), 24 h, 3 days (d), 7 d, 14 d, and 28 d following the last dose administered. Observed gross pathology and liver weights were recorded at time of necropsy. Liver, kidney, brain, spleen and pancreas from each rat were harvested, flash frozen in liquid nitrogen, and stored at -80.degree. C.
Frozen Liver was homogenized and lysed in TRIZOL reagent (Cat. #10296-028; Life Technologies, Inc, Gaithersburg, Md.) following the modifications for liver RNA isolation. Poly(A+) RNA was isolated using an OLIGOTEX kit (QIAGEN, Inc., Chatsworth, Calif.) and labeled with either Cy3 or Cy5-labeled primers (Operon Technologies, Alameda, Calif.) using the GEMBRIGHT labeling kit (Incyte). mRNA isolated from tissues of rats dosed with clofibrate was labeled with Cy5 and mRNA isolated from tissues of rats dosed with DMSO was labeled with Cy3. Quantitative and differential expression pattern control cDNAs were added to each labeling reaction. Labeled cDNA was treated with 0.5 M sodium bicarbonate (pH 9.2) for 20 min at 85.degree. C. to degrade the RNA and purified using two successive CHROMA SPIN 30 gel filtration spin columns (Clontech, Palo Alto, Calif.). Cy3 labeled control sample and Cy5 labeled experimental sample were combined and precipitated in glycogen, sodium acetate, and ethanol.
VIII Hybridization
Hybridization reactions contained 9 .mu.l of probe mixture consisting of 0.2 .mu.g each of both Cy3 and Cy5 labeled cDNA synthesis products in 5.times. SSC, 0.2% SCS hybridization buffer. The probe mixture was heated to 65.degree. C. for 5 minutes and was aliquoted onto the microarray surface and covered with an 1.8 cm.sup.2 coverslip. The arrays were transferred to a waterproof chamber having a cavity just slightly larger than a microscope slide. The chamber was kept at 100% humidity internally by the addition of 140 .mu.l of 5.times. SSC in a corner of the chamber. The chamber containing the arrays was incubated for about 6.5 hours at 60.degree. C. The arrays were washed for 10 min at 45.degree. C. in low stringency wash buffer (1.times. SSC, 0.1% SDS), three times for 10 minutes each at 45.degree. C. in high stringency wash buffer (0.1.times. SSC), and then dried.
IX Detection
The microscope used to detect the reporter-labeled hybridization complexes was equipped with an Innova 70 mixed gas 10 W laser (Coherent Lasers, Santa Clara, Calif.) capable of generating spectral lines at 488 nm for excitation of Cy3, and 632 nm for excitation of Cy5. The excitation laser light was focused on the array using a 20.times. microscope objective (Nikon). The slide containing the array was placed on a computer-controlled X-Y stage on the microscope and raster-scanned past the objective. The 1.8 cm.times.1.8 cm array used in the present example was scanned with a resolution of 20 micrometers.
In two separate scans, a mixed gas multiline laser excited the two fluorophores sequentially. Emitted light was split, based on wavelength, into two photomultiplier tube detectors (PMT R1477, Hamamatsu Photonics, San Jose, Calif.) corresponding to the two fluorophores. Appropriate filters positioned between the array and the photomultiplier tubes were used to filter the signals. The emission maxima of the fluorophores used were 565 nm for Cy3 and 650 nm for Cy5. Each array was typically scanned twice, one scan per fluorophore using the appropriate filters at the laser source, although the apparatus was capable of recording the spectra from both fluorophores simultaneously.
The sensitivity of the scans was typically calibrated using the signal intensity generated by a cDNA control species added to the probe mix at a known concentration. A specific Location on the array contained a complementary DNA sequence, allowing the intensity of the signal at that location to be correlated with a weight ratio of hybridizing species of 1:100,000. When two probes from different sources (e.g., representing test and control cells), each labeled with a different fluorophore, are hybridized to a single array for the purpose of identifying genes that are differentially expressed, the calibration was done by labeling samples of the calibrating cDNA with the two fluorophores and adding identical amounts of each to the hybridization mixture.
The output of the photomultiplier tube was digitized using a 12-bit RTI-835H analog-to-digital (A/D) conversion board (Analog Devices, Norwood, Mass.) installed in an IBM-compatible PC computer. The digitized data were displayed as an image where the signal intensity was mapped using a linear 20-color transformation to a pseudocolor scale ranging from blue (low signal) to red (high signal). The data was also analyzed quantitatively. Where two different fluorophores were excited and measured simultaneously, the data were first corrected for optical crosstalk (due to overlapping emission spectra) between the fluorophores using each fluorophore's emission spectrum.
A grid was superimposed over the fluorescence signal image such that the signal from each spot was centered in each element of the grid. The fluorescence signal within each element was then integrated to obtain a numerical value corresponding to the average intensity of the signal. The software used for signal analysis was the GEMTOOLS gene expression analysis program (Incyte).
