Research Abstract

In this study, we found that expression of intracellular renin increased both in cytosol and mitochondriaduring ischemia in diabetic heart, and that increased renin protects cardiomyocytes from ischemic injury. This protective effect of renin is due to the reduction of UCP and acceleration of electron transport chain, which resulted in the prevention of mitochondrial depolarization and preservation of ATP production under ischemic stress. The cardioprotective effect of renin is independent from subsequent intracellular angiotensin II production.
These results indicated that in contrast to previously reported adverse effects of circulating RAS, cytosolic renin plays an important role to protect myocytes from ischemic stress in diabetic heart.
