Abstract: The present invention provides a novel human gene ZNFN3A1 whose expression is markedly elevated in a great majority of HCCs compared to corresponding non-cancerous liver tissues. The gene encodes a protein having a zinc finger domain as well as a SET domain and has been found to form a regulatory complex with RNA helicase and RNA polymerase.

Abstract: The present invention features a method for determining the methyltransferase activity of a polypeptide and screening for modulators of methyltransferase activity, more particularly for modulators of the methylation of retinoblastoma by SMYD3. The invention further provides a method or pharmaceutical composition for prevention or treating of colorectal cancer, hepatocellular carcinoma, bladder cancer and/or breast cancer using a modulator so identified. N-terminal truncated forms of SMYD3 (alias ZNFN3A1) have higher methylating activity. Lys 824 is a preferred methylation site on the RB1 protein for SMYD3.

Abstract: Objective methods for detecting and diagnosing breast cancer (BRC) are described herein. Also described are methods of treating and preventing breast cancer and breast cancer metastasis as well as methods of assessing the prognosis of a breast cancer subject and the efficacy of a breast cancer therapy. In one embodiment, the diagnostic method involves determining the expression level of ZNFN3A1, a gene whose expression is markedly elevated in breast cancers, that therefore can be used to discriminate between BRC cells and normal cells. The present invention further provides methods of screening for therapeutic agents useful in the treatment of BRC, methods of treating BRC and method for vaccinating a subject against BRC.

Abstract: Objective methods for detecting and diagnosing Colorectal and gastric carcinomas are described herein. In one embodiment, the diagnostic method involves the determining a expression level of colon or gastric cancer-associated gene that discriminate between colon or gastric cancer and normal cell. The present invention further provides methods of screening for therapeutic agents useful in the treatment of colonic cancer and method of vaccinating a subject against colon or gastric cancer.

Abstract: This invention demonstrates that the PEG10 protein suppresses apoptosis and promotes cancer cell growth. Furthermore, PEG10 protein was found to be degraded through interaction with SIAH1 protein. This invention provides methods of regulating cell growth and cell death using the PEG10 protein. Furthermore, the present invention provides methods of screening for novel anticancer agents which use the PEG10 protein. The screening of this invention enables development of pharmaceutical agents that induce apoptosis and suppress cell growth by specifically targeting cancer cells. In particular, since the PEG10 protein is specifically expressed in hepatoma cells, it is an ideal target molecule for diagnosis and treatment of hepatoma.

Abstract: Objective methods for detecting, diagnosing, treating and preventing hepatocellular carcinoma (HCC) are described herein. In particular, the present invention relates to two genes up-regulated in HCC cells as compared to normal cells, referred to herein as MGC47816 and HES6. In one embodiment, the diagnostic method involves the determining the expression level of MGC47816 or HES6 that discriminate between hepatocellular carcinoma cells and normal cells. The present invention further provides methods of screening for therapeutic agents useful in the treatment of HCC, methods of treating HCC, and methods for vaccinating a subject against HCC.
