September 2012 Researcher of the Month - Xiaoping Shen, MD

Xiaoping Shen, MD

Current Research:
The quality of life and the lives of diabetic patients are severely affected by diabetic complications. So, many researchers from all over the world are working very hard trying to find ways either to prevent complications from happening or to reduce the damage from complications.   In addition, researchers are all trying to understand the mechanisms behind the complications. I am one of these researchers.

Currently, I’m working on two major projects.   The first entails investigating if the RAGE gene regulates macrophagecholesterol efflux. The second tests the following hypotheses: RAGE impairs angiogenesis consequent to femoral artery ligation in diabetic mice.

Future Plans:
In the future, I would like to extend my research to a larger range, such as investigating if the RAGE gene regulates macrophage reverse cholesterol transport in vivo or try some new methods to treat diabetic complications.
