The present invention provides therapeutic agents and methods for treating cancer using the polypeptides composed of an amino acid sequence which includes a polypeptide fragment of DEPDC1. The polypeptides of the present invention can be introduced into cancer cells by modifying the polypeptides with transfection agents such as poly-arginine. Furthermore, the present invention provides methods of screening for therapeutic agents or compounds useful in inhibition of the DEPDC1/ZN-F224 complex formation or the treatment of cancer. The present invention also provides siRNAs targeting the ZNF224 gene, which are suggested to be useful in the treatment of bladder cancer.

Method for treating or preventing bladder cancer using the DEPDC1 polypeptide

Objective methods for diagnosing a predisposition to developing cancer, particularly bladder cancer, gastric cancer, colorectal cancer, breast cancer, esophageal cancer, lung cancer, lymphoma, pancreatic cancer and testicular cancer, are described herein. In one embodiment, the diagnostic method involves determining an expression level of PRMT1 gene. The present invention further provides methods of screening for therapeutic agents useful in the treatment of PRMT1 associated disease, such as a cancer, e.g. bladder cancer, gastric cancer, colorectal cancer, breast cancer, esophageal cancer, lung cancer, lymphoma, pancreatic cancer and testicular cancer. The present invention further provides methods of inhibiting the cell growth and treating or alleviating symptoms of PRMT1 associated diseases. The present invention also features products, including double-stranded molecules and vectors encoding thereof as well as to compositions comprising them.

PRMT1 for target genes of cancer therapy and diagnosis

The present invention relates to anti-CDH3 antibodies, which can be labeled with a radioisotope. Moreover, the present invention provides methods and pharmaceutical compositions that comprise an anti-CDH3 antibody as an active ingredient. Since CDH3 is strongly expressed in pancreatic, lung, colon, prostate, breast, gastric or liver cancer cells, the present invention is useful in pancreatic, lung, colon, prostate, breast, gastric or liver cancer therapies.
