About Guoxun Chen

Guoxun Chen, an Assistant Professor in the Department of Nutrition, recently received the prestigious Young Investigator Award from the Council on Nutrition, Physical Activity and Metabolism, American Heart Association (AHA), as well as a Scientist Development Grant of $308,000 to support his research on the roles of vitamin A in the regulation of sugar and fat metabolism. Chen was invited to be a featured speaker at the national AHA Scientific Meeting in Orlando, Florida in November 2009. His future research will focus on the roles of vitamin A in the development of metabolic diseases.
Chen explores the mechanisms for how diet regulates the way we metabolize sugars and fats, particularly when the normal metabolism of these nutrients is disturbed. Chen has noticed that insulin, the body’s hormone that regulates blood sugar, acts in concert with vitamin A, an essential micronutrient that has traditionally been associated with night vision. Chen and his group found that vitamin A and its derivatives are responsible for regulating activities of enzymes involved in sugar and fat metabolism in liver cells.
