Prostate cancer (PC) is initially dependent on androgen receptor (AR) signaling for survival and growth. Therapeutics designed to repress AR activity, such as those reducing circulating androgen levels, serve as the primary intervention for advanced disease. However, supraphysiological androgen (SPA) concentrations, can produce a paradoxical response leading to growth inhibition. We sought to determine the mechanisms by which SPA represses PC growth and determine if molecular context associates with anti-tumor effects.
