PGC-1α regulates the mitochondrial antioxidant defense system in vascular endothelial cells

Abstract

These results unveil a novel regulatory pathway that links mitochondrial activity and mitochondrial oxidative stress protective systems. In addition, they suggest that PGC-1alpha could play a crucial protective role in vascular complications of diabetes, where the mitochondrial metabolism of glucose has been shown to result in oxidative stress and vascular endothelial cell dysfunction.
