My area of clinical interest is in genito-urinary malignancies, including developing multi-modal therapies in patients with high risk prostate cancer and recurrent prostate cancer. In addition, our aim is to help identify and develop active treatment regimens for advanced, hormone resistant prostate cancer and advanced bladder cancer. Another area of active ongoing work is related to the problem of bone metastasis, which is a particularly relevant issue in advanced prostate cancer. We are developing and testing several novel treatment combinations for all the above disease states of prostate cancer. Currently I am the Principal Investigator of ten active clinical trials in prostate cancer and bladder cancer.
My laboratory research is directed in two areas:
- We are using two pre-clinical mouse models of prostate cancer, including a xenograft model and a transgenic model (TRAMP) to study the antitumor effects of chemotherapy and hormone ablation, with the aim to determine optimal integration of these treatment modalities for therapeutic effect. These studies are being complimented with immunohistochemical analysis of various markers of apoptosis, angiogenesis and cell proliferation.
- The second area of research is to study mechanisms of drug resistance and cell signaling in human prostate cancer cells that have been selected for resistance to agents that disrupt cellular calcium homeostasis and microtubular stability.
Our research program has been supported by clinical grants, the National Institutes of Health and the Department of Veterans Affairs.
