Role of nitric oxide in resveratrol-induced renal protective effects of ischemic preconditioning

It is now well established that brief periods of ischemia followed by reperfusion render a variety of tissues tolerant to subsequent ischemia/reperfusion-induced injury. This phenomenon, referred to as ischemic preconditioning, was first demonstrated in the dog myocardium. The potential for clinical application of such a powerful protective phenomenon has generated enormous interest in identifying the underlying intracellular signaling pathways, with the ultimate aim of pharmacologically exploiting these mechanisms to develop therapeutic strategies that can enhance tolerance to ischemia/reperfusion injury in patients. This study explored the possible involvement of nitric oxide in renal ischemic preconditioning.
