Targeting metabolism to develop new prostate cancer treatments
Date:2/27/2014

ing metabolic-targeted therapies directed toward this signaling cascade for the treatment of prostate cancer, and we look forward to exploring this and other metabolic pathways further in order to develop the next generation of cancer therapies."

In their studies, Frigo's team showed that prostate cancer cells respond to androgens not only by increasing the breakdown of sugars, a process known as glycolysis that is commonly seen in many cancers, but also escalating the metabolism of fats. While much of the research on cancer metabolism has historically focused on glycolysis, the researchers say it's now becoming apparent that not all cancers depend solely on sugars.

Their findings further indicate that the metabolic changes brought about by the AMPK enzyme result in distinct growth advantages to prostate cancer cells. They say, however, that our understanding of how androgen receptor signaling impacts cellular metabolism and what role this has in disease progression remains incomplete.

The Frigo lab is one of several within the CNRCS concentrated on the role of nuclear receptors in cancer prevention and treatment, and his team has long studied the androgen receptor, which turns on or off various signaling pathways. Frigo believes these pathways hold the potential for better cancer treatments. Targeting these underexplored metabolic pathways for the development of novel therapeutics, Frigo's ultimate goal is to unlock more effective and less harmful cancer treatment alternatives.

With funding from the Department of Defense, National Institutes of Health, Texas Emerging Technology Fund and Golfers Against Cancer, Frigo's latest research appears in Nature's Oncogene. One of the world's leading cancer journals, Oncogene covers all aspects of the structure and function of genes that have the potential to cause cancer and are often mutated or expressed at high levels in tumor cells.
