Study could improve treatments for prostate cancerVan Andel Research Institute (VARI) researchers have determined how two proteins mandatory for the initiation and development of prostate cancer interact at the molecular level, which could lead to improved therapys for the disease.
One of the proteins, androgen receptor, is already an important drug target for prostate cancer. The other, steroid receptor coactivator-3 (SRC3), was originally identified for its role in the development of........Go to the Prostate-cancer-blog (Added on 4/2/2010 7:14:05 AM)
