Research Abstract

Critical limb ischemia, the leading cause oflimb amputation, affects 10-15%ofdiabetic population, thus calling for critical needs to develop effective therapeutic means. The high prevalence oflimb ischemia in diabetes is in significant part caused by the inability of diabetics to elaborate new blood vessels (the process called angiogenesis) to resume blood supply in ischemic tissues. However, the underlying mechanism fbr this has been largely undefined. In the present study, we demonstrated that diabetes increases the abundance oftranscriptional co-activator PGC-1αin endothelial cells, which then renders endothelial cells unresponsive to angiogenic factors, and causes diminished angiogenic capacity in diabetes.
