Prostate carcinoma is the most commonly diagnosed cancer in men, and the second leading cause of death due to cancer in Western civilization. Androgen ablation therapy is effective in treating androgen-dependent tumors, but eventually, androgen-independent tumors recur and are refractory to conventional chemotherapies. Tumor recurrence is often due to reactivation of androgen receptor (AR) signaling but is also accompanied by deregulation of cell cycle and proliferative controls. The mechanism by which AR promotes proliferation has not been established. The RB/E2F pathways has been shown to be deregulated in prostate tumors, but recent studies indicate that E2F3 overexpression is predictive of a poor clinical outcome. However it is currently unknown how E2F3 contributes to tumorigenesis. My lab is dedicated to defining the molecular mechanisms that govern tumor progression. We currently have three main projects in the lab: 1. Regulation of AR dependent gene expression and cellular proliferation in prostate cancer 2. The interplay between E2F3 overexpression, RB deregulation and the AR in prostate tumorigenesis 3. The role of E2F3B isoform in prostate tumorigenesis
