Treatment designed to block androgen receptor (AR) signaling in prostate cancer is the first known example of a "precision medicine" approach to cancer therapy that continues to be the major focus of treatment for advanced prostate cancer. A major focus of the lab has been the identification of down-stream ''effector'' genes that are responsible for cellular events (e.g. proliferation) after androgen receptor (AR) activation. We have identified a network of genes that are regulated by androgens in prostate cancer cells. Systematic studies involving the genetic and pharmacological modulation of these genes are designed to determine their cellular function with the aim of identifying those genes involved in proliferation, anti-apoptosis, differentiation, and treatment resistance. Genes with prostate-restricted expression serve as therapeutic targets for immunological and pharmacological strategies.
