76 results about "Tumour suppressor gene" patented technology

Tumour suppressor gene, also called antioncogene, any of a class of genes that are normally involved in regulating cell growth but that may become cancer-causing when damaged. Tumour suppressor genes encode for proteins that are involved in inhibiting the proliferation of cells, which is crucial to normal cell development and differentiation.

PROBLEMThere 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 SOLVINGAn 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.

Development and use of a new orthotopic, genetically tractable non-human animal model for liver cancer

This invention provides a genetically tractable in situ non-human animal model for hepatocellular carcinoma. The model is useful, inter alia, in understanding the molecular mechanisms of liver cancer, in understanding the genetic alterations that lead to chemoresistance or poor prognosis, and in identifying and evaluating new therapies against hepatocellular carcinomas. The liver cancer model of this invention is made by altering hepatocytes to increase oncogene expression, to reduce tumor suppressor gene expression or both and by transplanting the resulting hepatocytes into a recipient non-human animal.
