Welcome to Prasanna Laboratory!

Dr. Prasanna's laboratory is part of the Department of Biomedical Engineering, a joint department within the School of Medicine and School of Engineering. Overall research theme in Prasanna's laboratory is to understand the mechanisms of cardiovascular diseases and develop innovative new therapies using technologies in modern medicine and bioengineering. Dr. Krishnamurthy’s laboratory focuses on several broad research areas: I) to study the molecular mechanisms involved in the progression of cardiovascular diseases II) understand how diabetes influences cardiovascular pathophysiology III) develop novel therapeutic strategies- to enhance stem cell therapeutic benefits (involving adult cells and induced pluripotent stem cells) and to promote cardiac regeneration and repair. Our laboratory uses molecular biology and modern classical research tools along with relevant surgical mouse models of cardiac diseases including myocardial infarction (LAD ligation), ischemia reperfusion and hypertrophy (ANG-II and TAC induced). Long-term goal of these studies is to identify new targets that can aid in development of future drugs and new therapies for prevention and treatment of cardiovascular disease complications in diabetes.
