The effect of aerobic training and resveratrol on some regulatory and executive factors of cardiomyocytes apoptosis in STZ-diabetic male rats

Background: The present study was conducted to investigate the effect of aerobic training with resveratrol supplementation on regulatory and executive factors of cardiomyocytes apoptosis in streptozocin diabetic male rats. Materials and methods: In an experimental study, 50 male rats were randomly divided into 5 groups of 10 healthy controls, diabetics, resveratrol supplements, aerobic training and complementary resveratrol + aerobic training. Diabetes was induced by single injection of streptozotocin (50 ml/kg). Training was done 5 days per week for 8 weeks. They did exercise on the treadmill at 15m/min, 5 min and gradient of 15%. At the end of the course, all animals were completely and similarly treated and 48 hours after the last training session, anesthetized and sacrificed. After cardiac out and homogenization, the concentration of BAX, Bcl-2 and Caspase3 was measured individually. Results: After induction of diabetes, the concentration of BAX and Caspase-3 significantly increased compared with healthy controls, while BCL-2 concentration decreased significantly. However, only exercise interaction and resveratrol had significant effect on BAX concentration and had no significant effect on Caspase-3 levels. Each exercise and resveratrol separately increased BCL-2 concentration, but their interactive effect was not significant. Conclusion: Aerobic exercise and resveratrol have a beneficial effect on cardiac apoptosis in inducing diabetes, but their interaction is not significant in the process of cardiac apoptosis. Of course, aerobic exercise and resveratrol could be used as complementary therapies for myocardial protection against invasive apoptosis induced by diabetes.
