Prostate cancer, Bladder Cancer, Androgen Receptor, Retinoblastoma (RB) E2F Transcription Factors
Our laboratory is studying urological malignancies, which are commonly diagnosed and a leading cause of death due to cancer in Western civilization.
Early prostate cancers require androgen to survive and proliferate; this dependence is exploited in treatment for disseminated disease. Therefore, androgen ablation is the first line of therapeutic intervention. Although these regimens are initially effective, tumors ultimately recur due to reactivation of androgen receptor (AR) signaling, causing treatment failure and patient morbidity. Despite the importance of understanding androgen action in the prostate, little is understood about the mechanisms underlying androgen dependence, and the means by which the androgen requirement is bypassed in relapsed tumors.
Bladder cancer shows a striking gender disparity where men are three times more likely to develop the disease than woman. Development of treatments for this disease has lagged and there have been few advances in the field. The AR has a role in this malignancy as well, although molecular mechanisms underlying this AR dependence are currently unknown.
My lab is dedicated to delineating the molecular mechanisms that govern urological tumor growth to identify new targets and strategies to eliminate these diseases.
