PROBLEM

There are provided induced malignant stem cells capable of in vitro proliferation that are useful in cancer research and drug discovery for cancer therapy, as well as processes for production thereof, cancer cells derived from these cells, and applications of these cells.

MEANS FOR SOLVING

An induced malignant stem cell capable of in vitro proliferation are characterized by satisfying the following two requirements:

• (1) having at least one aberration selected from among (a) an aberration of methylation (high or low degree of methylation) in a tumor suppressor gene or a cancer-related genetic region in endogenous genomic DNA, (b) a somatic mutation of a tumor suppressor gene or a somatic mutation of an endogenous cancer-related gene in endogenous genomic DNA, (c) abnormal expression (increased or reduced/lost expression) of an endogenous oncogene or an endogenous tumor suppressor gene, (d) abnormal expression (increased or reduced/lost expression) of a noncoding RNA such as an endogenous cancer-related microRNA, (e) abnormal expression of an endogenous cancer-related protein, (f) an aberration of endogenous cancer-related metabolism (hypermetabolism or hypometabolism), (g) an aberration of endogenous cancer-related sugar chain, (h) an aberration of copy number variations in endogenous genomic DNA, and (i) instability of microsatellites in endogenous genomic DNA in an induced malignant stem cell; and
• (2) expressing genes including POU5F1 gene, NANOG gene, SOX2 gene, and ZFP42 gene.

Amplification and overexpression of theHER-2 oncogene in breast cancer is felt to be stable over the course of disease and concordant between the primary tumor and metastases. Therefore, patients with HER-2 negative primary tumors will rarely receive anti-HER-2 antibody therapy. A very sensitive blood test is used to capture circulating tumor cells (CTC's) and evaluate their HER-2 gene status by FISH evaluation. The HER-2 status of the primary tumor and corresponding CTC's is used to assess the ratio of CTC's as a reliable surrogate marker. HER-2 expression of 10 CTC's is sufficient to make a definitive diagnosis of the HER-2 gene status for the whole population of CTC's in patients with recurrent breast cancer.

Contemplated systems and methods allow for computational genomic analysis using paired-end sequence analysis and split read refinement to thereby identify high-confidence breakpoints associated with high copy numbers and orientation of rearrangements, which is then the basis for full reconstruction of double minutes (DM). In especially preferred aspects, the DM will also include an oncogene or tumor suppressor gene, and/or may be found in blood or blood derived fluids.

This invention relates to a peptide or protein capable of converting a transcription factor into a transcriptional repressor, a gene encoding such peptide or protein, a chimeric protein in which the aforementioned peptide or protein is fused to a transcription factor, a chimeric gene in which the gene encoding a peptide or protein is fused to a gene encoding a transcription factor, a recombinant vector having such chimeric gene, and a transformant comprising such recombinant vector. The peptide of the invention that is capable of converting a transcription factor into a transcriptional repressor is very short. Thus, it can be very easily synthesized, and it can effectively and selectively repress the transcription of a specific gene. Accordingly, such gene is applicable to and useful in a wide variety of fields, such as repression of the expression of cancerous genes and regulation of the expression of genes encoding pigment-metabolic enzymes.
