1. Technical Field
The present invention relates to cancer cell-specific apoptosis-inducing agents that target chromosome stabilization-associated genes and methods of screening for the apoptosis-inducing agents.
2. Background Art
Chromosomes are maintained in a stable state within cells by the action of various cellular functions (genes). Examples of typical cellular functions (genes) that contribute to this chromosome stabilization are as follows:
(a) Genes Associated with Human Chromosomal Instability Disorders
Chromosome breakage, deletion, translocation, and aneuploidy are observed in cells from patients with human chromosomal instability disorders, and these cells are also sensitive to DNA damage-inducing drugs. The occurrence of such instabilities indicates that human chromosomal instability disorder-associated genes are involved in chromosome stabilization.
(b) Chromosomal DNA Replication Reaction Including Initiation of Chromosomal DNA Replication and Progression of Replication Fork
The chromosomal DNA replication reaction plays the role of replicating chromosomal DNA during cell proliferation. It has the function of maintaining the number of chromosomes by accurately doubling the chromosomes when a cell divides into two cells.
(c) DNA Damage Checkpoints
DNA damage checkpoints play the role of checking for DNA damage, including breakage, chemical modification, and crosslinking, in chromosomes when the cell cycle advances from each of G1, S, G2, and M phases to the next phase. These checkpoints have the function of removing chromosomal DNA damage before proceeding to the next stage of the cell cycle.
(d) Sister Chromatid Agglutination and Separation
Sister chromatid agglutination and separation play the role of accurately separating, into daughter cells, sister chromatids in somatic cells in which replication has been completed.
(e) Base Excision Repair
Base excision repair plays the role of removing modified bases when a chemical modification damage, including oxidation and methylation, has occurred in bases in chromosomal DNA.
(f) Mismatch Excision Repair
Mismatch excision repair plays the role of recognizing mismatched base pairs other than the correct G-C and A-T base pairs present in chromosomal DNA, and repairing them to the correct base pairs.
(g) Nucleotide Excision Repair
Nucleotide excision repair plays the role of repairing DNA by recognizing and removing DNA damage such as cyclobutane pyrimidine dimers and 6-4 photoproducts, which occur in chromosomal DNA due to ultraviolet irradiation, and DNA internal crosslinking, which occurs between adjacent bases in chromosomal DNA due to cisplatin.
(h) Homologous Recombination Repair
Using an undamaged homologous chromosome as a template, homologous recombination repair plays the role of repairing various DNA damage, including breaks and gaps occurring in chromosomal DNA, and DNA damage resulting from incomplete repair by mechanisms such as base excision repair, mismatch excision repair, and nucleotide excision repair.
(i) Non-Homologous End-Joining Repair (Non-Homologous Recombination Repair)
Non-homologous end joining repair (non-homologous recombination repair) plays the role of repairing double-strand breaks in chromosomal DNA by joining the ends.
(j) Double-Strand DNA Break Repair
Double-strand DNA break repair plays the role of repairing double-strand breaks occurring in chromosomal DNA. This repair mechanism includes homologous recombination repair and non-homologous end joining repair (non-homologous recombination repair).
(k) DNA Post-Replication Repair (DNA Damage Tolerance)
DNA post-replication repair (DNA damage tolerance) is a mechanism that enables repair of a damaged DNA strand when damaged chromosomal DNA is replicated. Residual DNA damage is repaired following replication by this mechanism.
(l) DNA Crosslink Damage Repair
DNA crosslink damage repair plays the role of repairing DNA crosslink damage within and between chromosomes caused by crosslinking agents such as cisplatin.
(m) DNA-Protein Crosslink Damage Repair
DNA-protein crosslink damage repair plays the role of removing covalently bonded complexes and crosslinked complexes when a covalently bonded enzyme protein-DNA complex, which is a reaction intermediate of DNA repair, has been formed, or a crosslinked complex between a base in chromosomal DNA and a protein has formed.
(n) DNA Polymerase
DNA polymerases play the role of carrying out DNA synthesis reactions in chromosome stabilization mechanisms such as replication, recombination, and repair.
(o) Nuclease
Nucleases play the role of decomposing DNA in chromosome stabilization mechanisms such as replication, recombination, and repair.
(p) Nucleotide Cleansing
Nucleotide cleansing plays the role of removing modified bases when chemical modification damage, including oxidation and methylation, has occurred in a base of a nucleotide serving as the substrate of a DNA synthesis reaction.
(q) Chromatin Structure Maintenance
Chromatin structure maintenance plays a role in chromosome stabilization mechanisms such as replication, recombination, and repair, through maintaining the higher order chromosomal structure.
(r) Telomere Structure Maintenance
Telomere structure maintenance plays an important role in chromosome stabilization via the control of chromosome end telomere length and the formation and maintenance of special higher order structures in telomere regions.
In addition, various genes related to the aforementioned functions have been reported to be involved in chromosome stabilization. For example, various findings have been reported regarding various genes involved in chromosome stabilization (see Non-Patent Documents 1 to 83).
However, the correlation between the aforementioned functions (genes) involved in chromosome stabilization and the induction of cancer-cell specific apoptosis was so far unknown.
An objective of the present invention is to provide cancer cell-specific apoptosis-inducing agents. More specifically, an objective of the present invention is to provide cancer cell-specific apoptosis-inducing agents having as an active ingredient a compound which inhibits chromosome stabilization, a compound which inhibits expression of a gene involved in chromosome stabilization, or a compound which inhibits a function of a protein encoded by the gene, and methods of screening for the apoptosis-inducing agents. Another objective of the present invention is to provide methods for producing an apoptosis-inducing agent as a pharmaceutical composition.
To achieve the above objectives, the present inventors examined whether apoptosis is induced cancer cell-specifically by abnormalities in various functions relating to chromosome stabilization in cells. The following functions that are deeply involved in chromosome stabilization were selected as cellular chromosome stabilization-associated functions: (a) genes associated with human chromosomal instability disorders, (b) chromosomal DNA replication reaction including initiation of chromosomal DNA replication and progression of replication fork, (c) DNA damage checkpoints, (d) sister chromatid agglutination and separation, (e) base excision repair, (f) mismatch excision repair, (g) nucleotide excision repair, (h) homologous recombination repair, (i) non-homologous end-joining repair (non-homologous recombination repair), (j) double-strand DNA break repair, (k) DNA post-replication repair (DNA damage tolerance), (l) DNA crosslink damage repair, (m) DNA-protein crosslink damage repair, (n) DNA polymerase, (o) nuclease, (p) nucleotide cleansing, (q) chromatin structure maintenance, and (r) telomere structure maintenance.
The present inventors examined the cancer cell apoptosis-inducing effects of various genes involved in each of the aforementioned functions using siRNA having expression inhibitory effects on the genes. As a result, it was found that apoptosis was induced in cancer cells when the expression of a plurality of genes involved in each of the aforementioned functions were inhibited, and that this brought about an inhibition of cancer cell proliferation. The present inventors also discovered that induction of apoptosis does not occur with respect to normal cells (wild-type cells) even if the expression of these genes were inhibited. These genes are considered to be target molecules for preparing highly superior anticancer agents (carcinostatics) having few adverse side effects.
The above results suggested that inhibition of the expression of genes involved in each of the aforementioned functions would be able to induce apoptosis. In addition, these genes are deeply involved in each of the aforementioned functions, and inhibition of the expression of the genes generally prevents the functions from working normally in cells. Thus, the aforementioned findings made by the present inventors indicates none other than the fact that cancer cell-specific apoptosis is induced to due to abnormalities in each of the aforementioned functions. Accordingly, compounds that inhibit the aforementioned functions are considered to have the action of inducing cancer cell-specific apoptosis.
In addition, abnormalities in the aforementioned functions are known to destabilize chromosomes. Thus, chromosome destabilization in cells is considered to trigger induction of cancer cell-specific apoptosis. Namely, compounds that inhibit chromosome stabilization in cells, or compounds that inhibit the function of genes involved in chromosome stabilization, are expected to serve as cancer cell-specific apoptosis-inducing agents.
The present invention provides cancer cell-specific apoptosis-inducing agents having as an active ingredient a compound which inhibits chromosome stabilization, a compound which inhibits expression of a gene involved in chromosome stabilization, or a compound which inhibits the function of a protein encoded by said gene, and methods of screening for said apoptosis-inducing agents.

The present inventors found that inhibition of chromosome stabilization induces cancer cell (tumor cells)-specific apoptosis.
First, the present invention provides cancer cell-specific (anti-cancer cell) apoptosis-inducing agents comprising a compound that inhibits chromosome stabilization.
The apoptosis-inducing agents of the present invention are characterized in that they have an action to selectively induce apoptosis in cancer cells. In the present invention, “cancer cell-specific” means that the agent substantially demonstrates an apoptosis-inducing action in cancer cells without demonstrating a substantial apoptosis-inducing action in normal cells. Preferably, it means that the agent has an apoptosis-inducing action against cancer cells without showing an apoptosis-inducing action against normal cells.
The term “apoptosis” generally refers to cell death actively induced by the cell itself due to a physiological condition. Morphological features of apoptosis include, for example, chromosome condensation in the cell nucleus, nuclear fragmentation, loss of microvilli on the cell surface, and cytoplasmic shrinkage. Thus, as used herein, the term “apoptosis-inducing action” refers to, for example, the action of inducing in cells any of the above-described morphological features of apoptosis, but is not limited to those described above. One skilled in the art can appropriately assess whether apoptosis induction is taking place in cells or not.
The cancer cell-specific apoptosis-inducing agents of the present invention are considered to be, for example, anticancer agents (carcinostatics) having an apoptosis-inducing action as a mechanism of function. Since the apoptosis-inducing agents of the present invention specifically induce apoptosis in cancer cells but do not induce apoptosis in normal cells, they are expected to be safe anticancer agents having few adverse side effects.
The “anticancer agent” as used herein, may also be referred to as a “carcinostatic agent”. The “anticancer agent” may also be expressed as an “antitumor agent”, “antitumor pharmaceutical”, “antitumor pharmaceutical composition”, etc.
In the present invention, “inhibition of chromosome stabilization” indicates, for example, reaching a state in which unrepaired damage remaining in chromosomal DNA has accumulated, and more specifically, a state in which regions with exposed single strand chromosomal DNA have accumulated, or a state in which a large number of breaks in double-strand DNA have appeared; however, “inhibition of chromosome stabilization” is not necessarily limited to these states.
In the present invention, “chromosome stabilization” is maintained, for example, by the following functions in cells. Thus, inhibition of the following functions inhibits chromosome stabilization.
(a) genes associated with human chromosomal instability disorders,
(b) chromosomal DNA replication reaction including initiation of chromosomal DNA replication and progression of replication fork,
(c) DNA damage checkpoints,
(d) sister chromatid agglutination and separation,
(e) base excision repair,
(f) mismatch excision repair,
(g) nucleotide excision repair,
(h) homologous recombination repair,
(i) non-homologous end-joining repair (non-homologous recombination repair),
(j) double-strand DNA break repair,
(k) DNA post-replication repair (DNA damage tolerance),
(l) DNA crosslink damage repair,
(m) DNA-protein crosslink damage repair,
(n) DNA polymerase,
(o) nuclease,
(p) nucleotide cleansing,
(q) chromatin structure maintenance, and
(r) telomere structure maintenance.
In a preferred embodiment of the present invention, inhibition of chromosome stabilization includes inhibition of any of the aforementioned functions (a) to (r).
Namely, a preferred embodiment of the present invention relates to cancer cell-specific apoptosis-inducing agents containing a compound which inhibits any of the aforementioned functions (a) to (r).
In the present invention, in order to inhibit any of the aforementioned functions (a) to (r), for example, the expression of a gene associated with the function (which may also be referred to as a “chromosome stabilization-associated gene” in the present specification) may be inhibited, or the function (activity) of a protein encoded by the gene may be inhibited.

A preferred embodiment of the present invention provides a cancer cell-specific apoptosis-inducing agent comprising as an active ingredient a compound which inhibits the expression of a chromosome stabilization-associated gene (for example, any of the aforementioned genes), or inhibits the function of a protein encoded by the gene.
Since the gene names described in the present specification are names which are widely and generally known, those skilled in the art are able to suitably acquire data on the nucleotide sequences of said genes from a public reference database or gene database (e.g., GenBank) based on the gene name.
Specific examples of the nucleotide sequences of the aforementioned genes of the present invention and amino acid sequences of proteins encoded by the genes are listed in the Sequence Listing. NCBI accession numbers by which sequence data on the genes can be acquired, and the relationships between the nucleotide sequences of genes acquired using said numbers and SEQ ID NOs, are shown in Tables 1 to 16. In addition, examples of amino acid sequences of proteins encoded by the aforementioned genes of the present invention are also shown in the Sequence Listing.
Each of the aforementioned genes may be assigned multiple accession numbers even for the same gene due to the presence of polymorphisms in the nucleotide sequence or the like. These “polymorphisms” are not limited to single nucleotide polymorphisms (SNPs) including a mutation of a single nucleotide by substitution, deletion, or insertion, and also include substitutions, deletions, and insertion mutations of several contiguous nucleotides. Thus, the nucleotide sequences of the aforementioned genes are not necessarily limited to sequences acquired according to the accession numbers described in Tables 1 to 16, or to the sequences described in SEQ ID NOs. 1 to 637 and 810 to 908. Similarly, the amino acid sequences of proteins encoded by the aforementioned genes are not particularly limited to the amino acid sequences described in SEQ ID NOs. 638 to 723 and 909 to 973.
The aforementioned proteins of the present invention are not limited to the amino acid sequences described in SEQ ID NOs. 638 to 723 and 909 to 973, and include proteins comprising amino acid sequences in which one or more of the amino acid residues in said amino acid sequences have been added, deleted, substituted, or inserted, and which are functionally equivalent to the proteins described in SEQ ID NOs. 638 to 723 and 909 to 973.
The chromosome stabilization-associated genes of the present invention (e.g., the aforementioned various genes) are normally of animal origin, more preferably of mammalian origin, and most preferably of human origin, but they are not particularly limited thereto.
Namely, the present invention is not limited to apoptosis-inducing agents specific for human cancer cells, and also includes apoptosis-inducing agents for cancer cells of nonhuman animals. Thus, nonhuman-animal homolog (counterpart) genes of the aforementioned genes are included in the genes of the present invention. For example, endogenous genes (e.g., homologs) in other animals corresponding to genes comprising each of the nucleotide sequences described in SEQ ID NOs: 1 to 637 and 810 to 908 are included. Endogenous DNA of other animals corresponding to DNA comprising the nucleotide sequences generally has high homology with DNA described in the SEQ ID NOs above. High homology refers to homology of 50% or more, preferably 70% or more, more preferably 80% or more, and even more preferably 90% or more (for example, 95% or more, or further 96%, 97%, 98%, or 99% or more). The homology can be determined by the mBLAST algorithm (Altschul et al. (1990), Proc. Natl. Acad. Sci. USA 87: 2264-8; Karlin and Altschul (1993), Proc. Natl. Acad. Sci. USA 90: 5873-7). In addition, the homologous DNA is thought to hybridize under stringent conditions with DNA described in the above SEQ ID NOs if it has been isolated from the living body. Here, “stringent conditions” are, for example, “2×SSC, 0.1% SDS, 50° C.”, “2×SSC, 0.1% SDS, 42° C.”, or “1×SSC, 0.1% SDS, 37° C.”, and more stringent conditions are “2×SSC, 0.1% SDS, 65° C.”, “0.5×SSC, 0.1% SDS, 42° C.”, or “0.2×SSC, 0.1% SDS, 65° C.”. Those skilled in the art are able to suitably acquire data (such as sequence data) relating to endogenous genes corresponding to each of the aforementioned genes of the present invention in other animals based on the nucleotide sequences described in the Sequence Listing.
In addition, the present invention provides compounds which inhibit expression of chromosome stabilization-associated genes (for example, any of the aforementioned genes).
Preferred examples of compounds of the present invention which inhibit expression of chromosome stabilization-associated genes (for example, any of the aforementioned genes) include double-strand RNA having an RNAi (RNA interference) effect on said genes. In general, the term “RNAi” refers to a phenomenon where target gene expression is inhibited by inducing disruption of the target gene mRNA. This disruption is caused by introducing into cells a double-stranded RNA that comprises, a) a sense RNA comprising a sequence homologous to the target gene mRNA sequence, and b) an antisense RNA comprising a sequence complementary to the sense RNA.
While details of the RNAi mechanism remains unclear, it is thought that an enzyme called DICER (a member of the RNase III nuclease family) decomposes double-stranded RNA into small fragments called “small interfering RNA” or “siRNA”, when it comes into contact with the double-stranded RNA. This siRNA is also included in the double-stranded RNA comprising RNAi activity of the present invention. Furthermore, DNAs that allow the expression of the double-stranded RNA of the present invention are also included in the present invention.
A preferred embodiment of the present invention provides a cancer cell-specific apoptosis-inducing agent comprising as an active ingredient a double-strand RNA capable of inhibiting expression of a chromosome stabilization-associated gene (for example, any of the aforementioned genes) by an RNAi effect (siRNA), where the double stranded RNA comprises a structure in which an RNA consisting of a nucleotide sequence described in any of SEQ ID NOs: 724 to 809 and 974 to 1063, is hybridized with an RNA consisting of a sequence complementary to said RNA.
For example, an example of a siRNA of the present invention comprising the nucleotide sequence described in SEQ ID NO: 724 (5′-ggaaaaucuggccacucucTT-3′) is an RNA molecule having the structure shown below (SEQ ID NOS: 1064 and 1065).
(In the above structure, “|” indicates a hydrogen bond.)
Molecules having a structure in which one end of the above RNA molecule is closed, such as siRNA having a hairpin structure (shRNA), are also included in the present invention. Namely, molecules able to form a double-stranded RNA structure within the molecules are also included in the present invention.
For example, a molecule such as 5′-ggaaaaucuggccacucuc (xxxx)n gagaguggccagauuuucc-3′ is also included in the present invention (SEQ ID NOS: 1064-1065). (The above “(xxxx)n” represents a polynucleotide consisting of an arbitrary number of nucleotides or sequences.)
A preferred embodiment of the aforementioned siRNA is a double strand RNA able to inhibit expression of a chromosome stabilization-associated gene (for example, any of the aforementioned genes) by an RNAi effect (siRNA), comprising a structure in which an RNA consisting of a nucleotide sequence described in any of SEQ ID NOs: 724 to 809 and 974 to 1063 is hybridized with an RNA consisting of a sequence complementary to the RNA. However, double-strand RNA, for example, having a structure in which one or more ribonucleotides are added to or deleted from an end of the double-strand RNA, for example, is also included in the present invention.
Specifically, the present invention provides DNAs (vectors) that allow the expression of a double-stranded RNA of the present invention. These DNAs (vectors) that allow the expression of a double-stranded RNA of the present invention are typically DNAs comprising a structure where a DNA encoding one strand of the double-stranded RNA, and a DNA encoding the other strand of the double-stranded RNA, are operably linked to a promoter. Those skilled in the art can readily prepare an above-described DNA of the present invention with routinely used genetic engineering techniques. More specifically, expression vectors of the present invention can be prepared by appropriately inserting DNA encoding an RNA of the present invention into various known expression vectors.
Although RNA used for RNAi is not required to be completely identical (homologous) to a chromosome stabilization-associated gene (for example, any of the aforementioned genes) or a partial region of the gene, it is preferably completely identical (homologous).
The present invention's double-strand RNA having RNAi effects is normally double-strand RNA comprising sense RNA consisting of a sequence homologous with an arbitrary contiguous RNA region in the mRNA of a chromosome stabilization-associated gene (for example, any of the aforementioned genes), and an antisense RNA consisting of a sequence complementary to the sense RNA. The length of the “arbitrary contiguous RNA region” is normally 20 to 30 bases, and preferably 21 to 23 bases. An example includes, but is not necessarily limited to, the length of an siRNA, having as one of the strands, an RNA described in any of SEQ ID NOs: 724 to 809 and 974 to 1063. However, even in the case of a long-strand RNA that does not have RNAi effects as is, the length of the double-stranded RNA of the present invention is not limited since the long-stand is expected to be degraded into siRNA having RNAi effects in cells. In addition, long double-strand RNA corresponding to the entire length or nearly the entire length of the mRNA of a chromosome stabilization-associated gene (for example, any of the aforementioned genes) can be degraded in advance with, for example, DICER, and the resulting degradation product can be used as an apoptosis-inducing agent of the present invention. This degradation product is expected to contain a double-strand RNA molecule (siRNA) having RNAi effects. In this method, it is not particularly required to select an mRNA region that is expected to have an RNAi effect. Namely, it is not necessarily required to accurately define a region on mRNA of a chromosome stabilization-associated gene (for example, any of the aforementioned genes) that has an RNAi effect. However, the various types of siRNA used in the Examples described later are more preferred.
In general, double-strand RNA having an overhang of several nucleotides on an end is known to have strong RNAi effects. Double-stranded RNAs of the present invention preferably have an overhang of several nucleotides on an end. The length of the nucleotides which form the overhang is not particularly limited. This overhang may be DNA or RNA. For example, the overhang preferably has two nucleotides. In the present invention, double-strand RNA having an overhang comprises, for example, TT (two thymines), UU (two uracils), or other nucleotides (most preferably molecules having double-strand RNA consisting of 19 bases and an overhang consisting of 2 nucleotides (TT)) can be preferably used. Molecules in which the nucleotides forming the overhang in this manner are DNA, and sequences homologous to a target mRNA sequence, are also included in the double-strand RNA of the present invention.
Examples of siRNA molecules of the present invention where the nucleotides of the overhang portion are TT include molecules having TT added to the 3′ side thereof, such as the molecule indicated below (SEQ ID NOS: 724 and 1066).
The aforementioned “double-strand RNA having an RNAi effect on a chromosome stabilization-associated gene” of the present invention can be suitably produced by those skilled in the art based on the nucleotide sequence of a chromosome stabilization-associated gene (for example, any of the aforementioned genes) targeted by said double-strand RNA. A nucleotide sequence of a chromosome stabilization-associated gene (for example, any of the aforementioned genes) can be easily acquired from a public gene database as described above. As an example, double-strand RNA of the present invention can be produced based on a nucleotide sequence described in any of SEQ ID NOs: 1 to 637 and 810 to 908. Namely, the selection of an arbitrary contiguous RNA region of mRNA, which is a transcription product of any of the nucleotide sequences described in SEQ ID NOs: 1 to 637 and 810 to 908, based on that sequence, and the production of double-strand RNA corresponding to that region, can be easily carried out by those skilled in the art. In addition, methods for selecting an siRNA sequence having more potent RNAi effects from an mRNA sequence which is a transcript of said sequences can be suitably carried out by those skilled in the art with reference to, for example, the following documents: Reynold et al. Nature biotechnology 22. 326-330 (2004), Ui-Tei et al. Nucleic Acids Res. 32. 936-948 (2004), Boese Q, Leake D, Reynolds A, Read S, Scaringe S A, Marshall W S, Khvorova A. Mechanistic insights aid computational short interfering RNA design. Methods Enzymol. 2005; 392:73-96., Snove O Jr, Nedland M, Fjeldstad S H, Humberset H, Birkeland O R, Grunfeld T, Saetrom P. Designing effective siRNAs with off-target control. Biochem Biophys Res Commun. 2004; 325(3):769-73., Yiu S M, Wong P W, Lam T W, Mui Y C, Kung H F, Lin M, Cheung Y T. Filtering of Ineffective siRNAs and Improved siRNA Design Tool. Bioinformatics. 200515; 21(2):144-51, Chalk A M, Wahlestedt C, Sonnhammer E L. Improved and automated prediction of effective siRNA. Biochem Biophys Res Commun. 2004; 319(1):264-74., Amarzguioui M, Prydz H. An algorithm for selection of functional siRNA sequences. Biochem Biophys Res Commun. 2004; 316(4):1050-8., Sioud M, Leirdal M. Potential design rules and enzymatic synthesis of siRNAs. Methods Mol. Biol. 2004; 252:457-69. In addition, if one of the strands has been determined (for example, a nucleotide sequence described in any of SEQ ID NOs: 724 to 809 and 974 to 1063), the nucleotide sequence of the other strand (complementary strand) can be easily determined by those skilled in the art. siRNA can be suitably produced by those skilled in the art using a commercially available nucleic acid synthesizer. To synthesize a desired RNA, custom synthesis services are also available.
All of the nucleotides in the siRNA of the present invention are not necessarily required to be ribonucleotides (RNA). Namely, in the present invention, one or more of the ribonucleotides which compose the siRNA may be the corresponding deoxyribonucleotides. This “corresponding” means that the nucleotides have identical base species (adenine, guanine, cytosine, and thymine (uracil)), but the structure of the sugar portion is different. For example, the deoxyribonucleotide corresponding to a ribonucleotide having adenine means a deoxyribonucleotide having adenine. In addition, the above “more” is not limited to a particular number but preferably means a small number around 2 to 5.
It is not essential to have information on the full-length nucleotide sequence of a gene (the target gene) from which the double-stranded RNA of the present invention is derived. It is enough that the arbitrary RNA region comprising consecutive nucleotides (for example, 20 to 30 nucleotides) which is to be selected has been identified. Thus, the double-stranded RNA of the present invention can be prepared based on the nucleotide sequence of a fragment of a gene, such as an Expressed Sequence Tag (EST), whose mRNA sequence has been determined partially, but not completely. The accession numbers and names of EST sequences in the GenBank database with a high homology to the aforementioned genes are shown below. However, this list includes only a few examples of the many EST sequences. Those skilled in the art can readily obtain sequence information on appropriate EST fragments from public databases.

A preferred embodiment of the present invention provides an apoptosis-inducing agent comprising double-strand RNA having RNAi effects and having as one of the strands thereof a contiguous RNA region of mRNA corresponding to a chromosome stabilization-associated gene (for example, any of the aforementioned genes) or any of the aforementioned ESTs.
As described above, each of the aforementioned genes may contain various polymorphisms even for the same gene. Those skilled in the art can suitably design an RNA sequence expected to have RNAi effects for any of the nucleotide sequences described in SEQ ID NOs: 1 to 637 and 810 to 908 or the aforementioned EST sequences by incorporating data from, for example, a public polymorphism database relating to any of the aforementioned genes. An apoptosis-inducing agent comprising such an RNA is also included in the present invention. In addition, RNA having optimum RNAi effects can be suitably selected by those skilled in the art from several types of double-strand RNA produced in the present invention to obtain an apoptosis-inducing agent.
Specific examples of the aforementioned “double-strand RNA having RNAi effects” of the present invention include siRNA molecules having as one of the strands of the double-strand RNA a nucleotide sequence described in
In addition, one of the RNA sequences of a double strand region in the aforementioned siRNA molecule is not necessarily limited to that which is completely identical to a nucleotide sequence described in any of the aforementioned SEQ ID NOs: 724 to 809 and 974 to 1063. For example, the aforementioned siRNA molecule may be an siRNA molecule having as one of the strands of the double-strand RNA a nucleotide sequence in which one or more nucleotides in the nucleotide sequence have been altered, as long as it has a function which inhibits expression of a gene of the present invention.
Namely, in a preferred embodiment of the present invention, double-strand RNA having RNAi effects is double-strand RNA having a function which inhibits expression of a gene of the present invention, in which one of the strands of the double strand is a nucleotide sequence having one or more nucleotide additions, deletions or substitutions to a nucleotide sequence described in any of SEQ ID NOs: 724 to 809 and 974 to 1063, and the other strand is a nucleotide sequence complementary to the nucleotide sequence. The above “more” usually refers to a small number, and more specifically, refers to 2 to 10, preferably 2 to 5, and more preferably 2 to 3. In addition, a preferred embodiment of the present invention provides an apoptosis-inducing agent in which the compound which inhibits expression of a chromosome stabilization-associated gene (for example, any of the aforementioned genes) is (a) or (b) below:
(a) an antisense nucleic acid to a transcription product, or a portion thereof, of a chromosome stabilization-associated gene of the present invention (for example, any of the aforementioned genes), or
(b) a nucleic acid having ribozyme activity which specifically cleaves a transcription product of a chromosome stabilization-associated gene of the present invention (for example, any of the aforementioned genes).
As used herein, the term “nucleic acid” refers to RNA and DNA. Methods well known to those skilled in the art for inhibiting (suppressing) the expression of a specific endogenous gene include those using antisense technology. Multiple factors contribute to the inhibition of a target gene expression by an antisense nucleic acid. These factors include, for example, inhibition of transcription initiation through triplex formation; inhibition of transcription through hybrid formation with a sequence at the site of a local open loop structure made by RNA polymerase; inhibition of transcription through hybrid formation with the RNA being synthesized; inhibition of splicing through hybrid formation with a sequence at an intron-exon junction; inhibition of splicing through hybrid formation with a sequence at the site of spliceosome formation; inhibition of transfer from the nucleus to the cytoplasm through hybrid formation with mRNA; inhibition of splicing through hybrid formation with a sequence at the capping site or poly(A) site; inhibition of translation initiation through hybrid formation with a sequence at the site of binding of the translation initiation factor; inhibition of translation through hybrid formation with a sequence at the ribosome binding site near the initiation codon; inhibition of peptide chain elongation through hybrid formation with a sequence at the site of the translational region or polysome binding site of the mRNA; and inhibition of gene expression through hybrid formation with a sequence at the site of interaction between the expression regulatory region and the transcriptional regulatory factor. Thus, an antisense nucleic acid inhibits target gene expression by inhibiting various processes, such as transcription, splicing, and translation (Hirashima and Inoue, Shin Seikagaku Jikkenkoza 2 (New Lecture for Experimental Biochemistry 2), Kakusan IV (Nucleic Acid IV), Replication and Expression of Genes; Ed., Japanese Biochemical Society, Tokyo Kagaku Dozin Co., Ltd., pp. 319-347, 1993).
Antisense nucleic acids used in the present invention may inhibit the expression of a chromosome stabilization-associated gene (e.g., any of the aforementioned genes) through any one of the actions described above. In one embodiment, an antisense sequence is designed to be complementary to the 5′-untranslated region of a chromosome stabilization-associated gene (e.g., any of the aforementioned genes) mRNA. Thus such an antisense sequence is expected to effectively inhibit translation of that gene. A sequence complementary to the coding region or 3′-untranslated region can also be used for this purpose. Thus, a nucleic acid comprising the antisense sequence corresponding to the sequence of the translated as well as the untranslated regions of the chromosome stabilization-associated gene (e.g., any of the aforementioned genes) can be included as an antisense nucleic acid used in the present invention. The antisense nucleic acid to be used is ligated downstream of an appropriate promoter and preferably ligated with a sequence comprising a transcription termination signal at the 3′ end. The antisense nucleic acid to be used for clinical applications is typically a synthetic oligomer. Such synthetic oligomers include the widely used S-oligo (phosphorothioate oligo nucleotide) in which S (sulfur) has been substituted for O (oxygen) at the phosphate ester bond, thus reducing sensitivity to nuclease digestion and maintaining antisense nucleic acid activity. S-oligo is currently being tested as an antisense drug in clinical trials where it is administered directly to affected areas. This S-oligo is also suitable for use in the present invention. It is preferable that the antisense nucleic acid sequence is complementary to the target gene sequence or a portion thereof; however perfect complementarity is not necessary as long as the antisense nucleic acid effectively suppresses target gene expression. The transcribed RNA has preferably 90% or higher complementarity, and most preferably 95% or higher complementarity to the target gene transcript. The length of the antisense nucleic acid used to effectively suppress target gene expression is at least 15 nucleotides or longer, preferably 100 nucleotides or longer, and more preferably 500 nucleotides or longer.
The inhibition of chromosome stabilization-associated gene (e.g., any of the aforementioned genes) expression can also be achieved using a ribozyme or ribozyme-encoding DNA. The term “ribozyme” refers to an RNA molecule comprising catalytic activity. Ribozymes can have a variety of activities, and can be designed to have the activity of cleaving RNA in a site-specific fashion. Ribozymes such as group I intron-type ribozymes and M1 RNA, which are RNase P ribozymes, are 400 nucleotides or more in length. Others such as hammerhead and hairpin ribozymes have active sites comprising about 40 nucleotides (M. Koizumi and E. Otsuka, Tanpakushitsu Kakusan Koso (Protein, Nucleic acid, and Enzyme), 1990, 35, 2191).
For example, the autolytic domain of a hammerhead ribozyme cleaves the 3′ side of C15 in the sequence G13U14C15. Base pairing between U14 and A9 plays an important role in this activity, and A15 or U15 can be cleaved instead of C15 (Koizumi, M. et al., FEBS Lett, 228: 228, 1988). A restriction enzyme-like RNA-cleaving ribozyme that recognizes the target RNA sequences UC, UU, or UA can be produced by designing the ribozyme such that the substrate binding site complements the RNA sequence near the target site (Koizumi, M. et al., FEBS Lett, 239: 285, 1988; M. Koizumi and E. Otsuka, Tanpakushitsu Kakusan Koso (Protein, Nucleic acid, and Enzyme), 35:2191, 1990; and Koizumi, M. et al., Nucl. Acids Res., 17: 7059, 1989).
The hairpin ribozyme can also be used for the purposes of the present invention. This ribozyme is found, for example, in the minus strand of tobacco ring spot virus satellite RNA (Buzayan, J. M., Nature, 323: 349, 1986). A target specific RNA-cleaving ribozyme can also be produced from a hairpin ribozyme (Kikuchi, Y. and Sasaki, N., Nucl. Acids Res., 19: 6751, 1991; Kikuchi, H., Kagaku to Seibutsu (Chemistry and Biology), 30: 112, 1992). Thus, the expression of a chromosome stabilization-associated gene of the present invention can be inhibited by specifically digesting the gene transcript using a ribozyme.
The present invention also relates to a cancer cell-specific apoptosis-inducing agent comprising as its active ingredient a compound which inhibits the function (activity) of a protein encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes).
A protein encoded by a chromosome stabilization-associated gene of the present invention includes mutant proteins or homolog proteins of a protein encoded by a chromosome stabilization-associated gene. Such mutant proteins or homolog proteins are functionally equivalent to the protein encoded by a chromosome stabilization-associated gene, and have an amino acid sequence with one or more amino acid deletions, substitutions, or additions to the amino acid sequence of the protein. Here, a “functionally equivalent protein” refers to a protein having a function which is similar to the function (for example, any of the functions of the aforementioned (a) to (s)) of a protein encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes).
Alternatively, a protein having, for example, 90% or more, desirably 95% or more, and more desirably 99% or more homology with the amino acid sequence of a protein encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes) can be indicated as a protein functionally equivalent to a protein encoded by a chromosome stabilization-associated gene.
A preferred embodiment of the present invention provides an apoptosis-inducing agent in which a compound which inhibits the function (activity) of a protein encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes) is a compound described in any of (a) to (c) below. These compounds are thought to have an apoptosis-inducing action against cancer cells by inhibiting (decreasing) the function or activity of a protein encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes).
(a) Mutant proteins having dominant negative traits with respect to a protein encoded by a chromosome stabilization-associated gene of the present invention (for example, any of the aforementioned genes).
(b) Antibodies which bind to a protein encoded by a chromosome stabilization-associated gene of the present invention (for example, any of the aforementioned genes).
(c) Low molecular weight compounds which bind to a protein encoded by a chromosome stabilization-associated gene of the present invention (for example, any of the aforementioned genes).
The “mutant proteins having dominant negative traits” in above (a) refer to mutants of a protein encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes) having a function to deactivate or decrease the activity of an endogenous wild-type protein.
The “antibodies” in above (b) can be prepared according to methods known to those skilled in the art. Polyclonal antibodies, for example, can be obtained in the following manner. Serum is obtained from a small animal such as a rabbit immunized with a protein encoded by a naturally-occurring or recombinant chromosome stabilization-associated gene (for example, any of the aforementioned genes) or a protein encoded by a recombinant chromosome stabilization-associated gene expressed in microorganisms such as Escherichia coli as a fusion protein with GST, or a partial peptide thereof. This serum is then purified by, for example, ammonium sulfate precipitation, protein A column and protein G column, DEAE ion exchange chromatography, or an affinity column coupled with a protein or synthetic peptide encoded by a chromosome stabilization-associated gene. In addition, monoclonal antibodies can be prepared by, for example, immunizing a small animal such as a mouse with a protein, or a partial peptide thereof, encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes), excising the spleen from the mouse, gently grinding the excised spleen to separate the cells, fusing the cells with mouse myeloma cells using a reagent such as polyethylene glycol, and selecting from the resulting fusion cells (hybridomas) those clones that produce an antibody which binds to the protein encoded by a chromosome stabilization-associated gene. Next, a hybridoma thus obtained is transplanted into the mouse abdominal cavity, peritoneal fluid is recovered from the mouse. The resulting monoclonal antibody can then be purified by, for example, ammonium sulfate precipitation, protein A column and protein G column, DEAE ion exchange chromatography, or an affinity column coupled with a protein or a synthetic peptide encoded by a chromosome stabilization-associated gene.
There are no particular restrictions on the antibody of the present invention so long as it is able to bind to a protein encoded by a chromosome stabilization-associated gene of the present invention (for example, any of the aforementioned genes). In addition to the aforementioned polyclonal antibody and monoclonal antibody, the antibody includes human antibodies, humanized antibodies obtained by genetic recombination, and antibody fragments and antibody modification products thereof.
There are no limitations on the animal species as the source of a protein encoded by a chromosome stabilization-associated gene of the present invention (for example, any of the aforementioned genes), which is used as a sensitizing antigen for acquiring antibody; however, a protein of mammalian origin, such as that from a mouse or human, is preferable, and a protein of human origin is particularly preferable.
Proteins to be used as a sensitizing antigen in the present invention may be intact proteins as well as partial peptides derived from those proteins. Such partial protein peptides include, for example, protein amino (N)-terminal fragments and carboxyl (C)-terminal fragments. As used herein, “antibody” usually refers to an antibody which reacts with a full-length protein or a fragment thereof.
In addition to obtaining the above-described hybridomas by immunizing non-human animals with an antigen, hybridomas producing a desired human antibody having binding activity with the protein can also be prepared in vitro by sensitizing human lymphocytes, for example, human lymphocytes infected with EB virus, with the protein, cells expressing the protein, or a lysate of those cells, and fusing these sensitized lymphocytes with immortalized human myeloma cells, for example, U266 cells. When an antibody of the present invention is intended to be administered into human bodies (antibody therapy), a human antibody or humanized antibody is preferable to reduce the immunogenicity.
Examples of compounds which are already known to bind to proteins encoded by chromosome stabilization-associated genes include monoclonal or polyclonal antibodies directed to a protein encoded by any of the aforementioned genes.
Compounds which inhibit the expression of a chromosome stabilization-associated gene (for example, any of the aforementioned genes) of the present invention or inhibit the function (activity) of a protein encoded by the gene may be naturally-occurring or artificial compounds. They are typically compounds which can be produced, obtained, or isolated using a method known to those skilled in the art. Examples of such compounds include single compounds such as organic compounds, inorganic compounds, nucleic acids, proteins, peptides, and sugars, as well as compound libraries, gene library expression products, cell extracts, cell culture supernatants, microbial fermentation products, marine organism extracts, plant extracts, and compounds isolated and purified from the extracts.
The present invention also provides methods of screening for cancer cell-specific apoptosis-inducing agents.
A preferred embodiment of the aforementioned methods of the present invention is a method which uses as an index the binding activity between a protein encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes), or a partial peptide thereof, and a test compound. Normally, a compound which binds to a protein encoded by a chromosome stabilization-associated gene, or a partial peptide thereof, is expected to have inhibitory effects on the function of a protein encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes).
In the aforementioned method of the present invention, a protein encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes), or a partial peptide thereof, is first contacted with a test compound. The protein encoded by a chromosome stabilization-associated gene, or partial peptide thereof, can be, for example, in a purified form of the protein encoded by a chromosome stabilization-associated gene, or partial peptide thereof, or in a form expressed within or outside cells, or in a form bound to an affinity column, depending on the index for detecting its binding to the test compound. Test compounds used in this method can be used after being suitably labeled as necessary. Examples of labels include radioactive labels and fluorescent labels.
In the present method, the binding activity between the protein encoded by the chromosome stabilization-associated gene, or partial peptide thereof, and the test compound, is then measured. Binding activity between the protein encoded by the chromosome stabilization-associated gene, or partial peptide thereof, and the test compound can be measured by, for example, a label attached to the test compound bound to the protein encoded by the chromosome stabilization-associated gene or partial peptide thereof. In addition, binding activity can also be measured using as an index a change in the activity of the protein encoded by the chromosome stabilization-associated gene expressed within or outside cells, or partial peptide thereof, which occurs due to binding of the test compound to the protein or partial peptide thereof.
In the present method, a test compound is then selected which binds to a protein encoded by a chromosome stabilization-associated gene (for example, any of the aforementioned genes), or partial peptide thereof.
There is no limitation as to the type of test compound used in the present invention. Such compounds include, but are not limited to, for example, single unmixed compounds of organic compounds, inorganic compounds, nucleic acids, proteins, peptides, sugars, natural compounds, and such; or compound libraries, expression products of gene libraries, cell extracts, cell culture supernatants, products of fermenting microorganisms, marine organism extracts, and plant extracts; and artificially synthesized compounds.
In an alternative embodiment of the screening method of the present invention, first, a test compound is contacted with cells that express a chromosome stabilization-associated gene (for example, any of the aforementioned genes), or with a cell extract prepared from such cells. The phrase “cells that express a chromosome stabilization-associated gene” described above includes cells expressing an endogenous chromosome stabilization-associated gene, and cells into which an exogenous chromosome stabilization-associated gene has been introduced and in which that gene is expressed. The cells in which an exogenous chromosome stabilization-associated gene is expressed can typically be prepared by introducing into host cells an expression vector which contains the gene. Those skilled in the art can prepare such an expression vector using routine genetic engineering techniques. In the screening methods of the present invention, cells expressing a chromosome stabilization-associated gene preferably include various tumor cells, for example, MCF7 (breast cancer), A549 (lung cancer), U20S (osteogenic sarcoma), C33A (cervical cancer), HT1080 (fibrosarcoma), PA-1 (ovarian teratocarcinoma), Tera2 (embryonal carcinoma), T24 (bladder cancer), K562 (chronic myelocytic leukemia), Molt4 (acute lymphoblastic leukemia), A172 (glioblastoma), HeLa (cervical cancer), HepG2 (hepatic cancer), ACC62 (melanoma), KP4 (pancreas cancer), CaKi-1 (kidney cancer), MKN45 (gastric cancer), LNcap (prostate cancer), MDA-MB435 (breast cancer), EJ 1 (bladder cancer), and OVCAR3 (ovarian cancer).
Typically, but without limitation, a test compound is Contacted with cells expressing a chromosome stabilization-associated gene by adding the test compound to a culture medium of the cells expressing the chromosome stabilization-associated gene (for example, any of the aforementioned genes). When the test compound is a protein, the contact can be achieved by introducing into the cells a DNA vector that allows protein expression.
The next step of this method comprises determining the expression level of the chromosome stabilization-associated gene. Herein, the phrase “gene expression” refers to both transcription and translation. The gene expression level can be determined using a method known to those skilled in the art. For example, mRNA can be extracted from cells expressing the chromosome stabilization-associated gene according to a conventional method, and by using this mRNA as a template, the transcriptional level of the gene can be determined using Northern hybridization or RT-PCR. Alternatively, the translational level of the gene can be determined by collecting protein fractions from the cells expressing the chromosome stabilization-associated gene, and then detecting the expression of the protein encoded by the gene using an electrophoresis method such as sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Furthermore, the translational level of the gene can be determined by detecting the expression of the encoded protein by Western blotting analysis using an antibody against the protein. There is no limitation as to the type of antibody used for detecting the protein encoded by the gene, as long as the protein can be detected. Such antibodies include, for example, both monoclonal and polyclonal antibodies.
In this method, a compound that it causes a reduction in expression level when compared to the expression level measured in the absence of a test compound (control) is then selected. The compound selected by the above-described procedure is expected to have the action of inducing apoptosis in cancer cells. This compound may be used as a carcinostatic (an anticancer agent) whose mode of action is based on apoptosis induction.
In an alternative embodiment of the screening method of the present invention, a compound that reduces the expression level of a chromosome stabilization-associated gene (for example, any of the aforementioned genes) of the present invention is selected using a reporter gene.
In this method, a test compound is first contacted with cells (or an extract of those cells) that comprise a DNA having a structure where a reporter gene is operably linked to a transcriptional regulatory region of a chromosome stabilization-associated gene (for example, any of the aforementioned genes). As used herein, the phrase “operably linked” means that the transcriptional regulatory region of the chromosome stabilization-associated gene is linked to a reporter gene in such a way as to induce reporter gene expression when a transcriptional factor binds to the transcriptional regulatory region of the gene. Thus, even when the reporter gene is connected with another gene and thus foi ins a fusion protein with that gene product, such a case is included in the meaning of “operably linked”, as long as the expression of the fusion protein is induced when the transcriptional factor binds to the transcriptional regulatory region of the gene. Using a known method and based on the cDNA nucleotide sequence for a chromosome stabilization-associated gene (for example, any of the aforementioned genes), those skilled in the art can obtain the transcriptional regulatory region of that gene within the genome.
There is no limitation as to the type of reporter gene used in this method, as long as the expression of the reporter gene can be detected. Such reporter genes include, for example, the CAT gene, lacZ gene, luciferase gene, and GFP gene. The “cells that comprise a DNA having a structure where a reporter gene is operably linked to a transcriptional regulatory region of a chromosome stabilization-associated gene” include, for example, cells into which a vector with a structure where a reporter gene is operably linked to a transcriptional regulatory region of a chromosome stabilization-associated gene (for example, any of the aforementioned genes) has been introduced. Those skilled in the art can prepare the above-described vector using routine genetic engineering techniques. The introduction of such a vector into cells can be achieved using a conventional method, for example, using calcium phosphate precipitation, electroporation, the lipofectarnine method, microinjection, etc. “Cells that comprise a DNA having a structure where a reporter gene is operably linked to a transcriptional regulatory region of a chromosome stabilization-associated gene” also includes cells in which that structure has been inserted into the chromosome. A DNA structure can be inserted into a chromosome by using a method routinely used by those skilled in the art, for example, a random integration or gene transfer method using homologous recombination.
An “extract of cells that comprise a DNA having a structure where a reporter gene is operably linked to a transcriptional regulatory region of a chromosome stabilization-associated gene” includes, for example, a mixture prepared by adding a DNA to a cell extract included in a commercially available in vitro transcription/translation kit, where that added DNA comprises a structure where a reporter gene is operably linked to a transcriptional regulatory region of a chromosome stabilization-associated gene (for example, any of the aforementioned genes).
In this method, the “contact” can be achieved by adding a test compound into a culture medium of “cells that comprise a DNA having a structure where a transcriptional regulatory region of a chromosome stabilization-associated gene is operably linked to a reporter gene”, or by adding a test compound into the above-described commercially available cell extract, which contains the DNA. However, the method of contact is not limited to the methods described above. When the test compound is a protein, the contact can also be achieved, for example, by introducing into the cells a DNA vector that directs the expression of the protein.
The next step of this method comprises determining the level of reporter gene expression. The expression level of the reporter gene can be determined by a method that depends on the type of the reporter gene and which is known to those skilled in the art. For example, when the reporter gene is the CAT gene, expression level can be determined by detecting the acetylation of chloramphenicol, mediated by the CAT gene product.
When the reporter gene is the lacZ gene, expression level can be determined by detecting color development in a chromogenic compound, mediated by the catalytic action of the lacZ gene expression product. When the reporter gene is the luciferase gene, the level can be determined by detecting the fluorescence of a fluorescent compound, mediated by the catalytic action of the luciferase gene expression product. Alternatively, when the reporter gene is the GFP gene, the level can be determined by detecting the fluorescence of the GFP protein.
The next step of this method comprises selecting compounds that reduce reporter gene expression level as compared to expression level determined in the absence of a test compound. The compounds selected by the above-described procedure can be cancer cell-specific apoptosis inducing agents.

The present invention's compounds which inhibit chromosome stabilization in cells or compounds which inhibit the function of a chromosome stabilization-associated gene have an action to induce cancer cell-specific apoptosis. Phamiaceutical compositions comprising such compounds are believed to become anticancer agents having apoptosis-induction as the mechanism of action, while also having few adverse side effects. The present invention provides, for the first time, cancer cell-specific anticancer agents which have apoptosis-induction as the mechanism of action and which target chromosome stabilization-associated genes.
Even if certain compounds are found to have an apoptosis-inducing action, it is difficult to use the compounds as pharmaceuticals when their apoptosis-inducing actions in normal cells are unknown. This is because there may be a risk of adverse effects when the compounds have apoptosis-inducing actions in normal cells. In other words, if the compounds have apoptosis-inducing actions not specific to cancer cells, in general, it is practically difficult to use the compounds as pharmaceuticals. Accordingly, the agents (the compounds) of the present invention are very practical and effective because their apoptosis-inducing actions are specific to cancer cells.
The mechanism by which apoptosis is induced cancer cell-specifically by inhibition of chromosome stabilization can be explained in the following manner based on findings of the present inventors.
Numerous cancer cells are known to have mutations or deletions in the cancer suppressor gene p53. In addition, oncogenesis is known to take place in some cases due to the occurrence of an abnormality in a DNA damage checkpoint mechanism. If the expression of functional chromosome stabilizing genes is inhibited by siRNA or the like and their functions are blocked in cancer cells having an abnormality in p53 or a DNA damage checkpoint mechanism, the chromosome stabilization mechanism will fail and it would no longer be possible to repair chromosomal DNA. In such cells, it is thought that apoptosis will be induced due to the residual DNA damage that has not been repaired. On the other hand, it is thought that in normal cells such as diploid fibroblasts, if the expression of functional chromosome stabilizing genes is inhibited by siRNA or the like and their functions are blocked, the cell cycle will be temporarily interrupted by the action of p53 and the DNA damage checkpoint mechanism, thereby enabling damage in chromosomal DNA to be repaired.
In addition to providing cancer cell-specific apoptosis-inducing agents, the present invention provides extremely useful academic findings for elucidating the mechanism of cancer cell-specific apoptosis induction.
