Abstract: The present invention provides a telomerase activity inhibiting polypeptide. The expression of the polypeptide in tumor cells can inhibit significantly tumor cell telomerase activity, tumor cell growth, and lead to the death of such cells. The present invention further provides a preparation method for the polypeptide and an application thereof in targeted treatments of tumors.

Abstract: A marker for the detection of liver cancer and application of the marker thereof. The application includes use of cytochrome p450 family 17 subfamily A polypeptide 1 (CYP17A1 protein) in the preparation of diagnostic reagents or kits for the detection of liver cancer kit. Studies have shown that CYP17A1 expression levels are higher in liver cancer tissues than in the adjacent healthy tissues, and the amount of CYP17A1 in sera of liver patients is significantly higher than that of healthy human population. Therefore, CYP17A1 can be used as a marker for the diagnosis of liver cancer (especially serological diagnosis).

Abstract: This invention provides a novel human liver regeneration associated protein hLRTM4 and the polynucleotide which encodes the hLRTM4 protein. Furthermore, this invention provides a method of preparing and using hLRTM4 protein, and its polynucleotides. hLRTM4 protein can be used to treat liver injury, and its antagonists (e.g. antisense nucleic acids and antibodies) can be used to treat hepatocellular carcinoma. This invention also provides the corresponding pharmaceutical compositions.

Abstract: The invention has disclosed a new tumor suppressor protein HCRP1, the polynucleotide sequences encoding this polypeptides, and methods for production of the polypeptide using the recombinant technology. The tumor suppression protein, HCRP1, is obtained through the positional candidate cloning strategy. It locates in 8p22 region of human chromosome. The full length cDNA for HCRP1 is 1916 bp, which encodes a protein of 397 amino acids. When introduced into liver cancer cells, HCRP1 can inhibit the malignant transformation of liver cancer cells.
