Use of p38/JTV-1 for treating cancer

摘要

This invention relates to a novel use of p38/JTV-1. More particularly, the invention relates to a p38/JTV-1 protein for use as medicament, a nucleic acid encoding for said protein, and a method for screening a pharmaceutical composition for the treatment of cancer characterized by selecting a substance having an effect on the increase in the activity of the p38/JTV-1 protein or the intracellular level thereof. The p38/JTV-1 according to the invention can be usefully used to treat cancer through the mechanism of suppressing the proliferation of cancer cells by binding to FBP (FUSE-binding protein) and thereby promoting the ubiquitination of FBP to downregulate c-myc gene, which is a proto-oncogene, and the mechanism of promoting the apoptosis of cells by binding to PDK-1 (phosphoinositide-dependent protein) and thereby inhibiting the phosphorylation of AKT (serine/threonine kinase). Also, p38/JTV-1 can be used as a target for screening of new anticancer agents, by virtue of such regulation mechanisms of p38/JTV-1.
