Brief description of current research: 

It is well known that diabetes is associated with poor outcomes in humans with PAD. Our lab and others have shown that mice with diabetes have poorer outcomes following experimental PAD exemplified by poor perfusion recovery and higher tendency to develop limb necrosis.  Therefore, one of our goals is to explore how specific metabolic abnormalities in diabetes affect expression and function of recently identified novel genes involved in favorable adaptation following experimental PAD.  Additionally, we have identified several miRNA’s that appear to play a role in impaired post-ischemic adaption in diabetes. We are currently investigating the molecular mechanisms underpinning the role of these miRNA’s in diabetes vascular complications. Lastly, we hope insights gained from these studies would guide development of novel therapies for treatment of PAD in diabetes.
