Dr. Ralph Buttyan is a Senior Research Scientist in the Vancouver Prostate Centre and has been involved in prostate cancer research for over 28 years. He recently joined the Prostate Centre from New York, USA, where he was Professor in Pathology and Urology at Columbia University and a Senior Scientist at the Ordway Research Institute.
His research interest lies in understanding the molecular and genetic changes that enable prostate cancer cells to acquire resistance to androgen ablation (hormone) and other types of therapies. These therapies are commonly used to deplete male steroids in patients when the prostate cancer has metastasized outside of the prostate. His past research included pioneering studies of the “cell suicide” process referred to as apoptosis, and he showed that genes that block this process become active as the prostate tumor develops therapy resistance. He was among the first to show the profound and early detrimental effects of androgen ablation on blood vessels that feed and oxygenate a prostate tumor. This work established hormone therapy as the earliest form of anti-angiogenic therapy used and it may provide clues as how to better use anti-angiogenic therapies for prostate cancer patients. His research was among the first to show the presence of circulating cancer cells in the bloods of prostate cancer patients and to attempt to use this criteria as a marker of future relapse after therapy.
