Evaluation of P53 and Nrf2 protein levels in kidney tissue after 8 weeks of endurance training in diabetic rats with morphine withdrawal syndrome

Abstract

Introduction: P53 protein is one of the factors regulating apoptosis and Nrf2 is the main regulator of antioxidant proteins. This study aimed to evaluate P53 and Nrf2 protein levels in kidney tissue after 8 weeks of endurance training in diabetic rats with morphine withdrawal syndrome. Materials and Methods: In this experimental study, 32 Wistar rats were used, which were randomly divided into 4 groups of 8. After inducing diabetes and creating dependence on morphine by oral method, the training groups performed an endurance training protocol for 8 weeks. The groups included: diabetes (D), morphine diabetes (D.M), diabetes+ endurance training (D.ET), and morphine diabetes+ endurance training (D.M.ET). On the last day of the study, all rats were killed and their kidneys were removed. The protein levels of the indicators of this study were measured by ELISA kits. Results: The results of this study showed that the P53 protein level in the D.ET training group (P=0.000) compared to the D group and the D.M.ET training group (P=0.002) compared to the D.M. group, has a significant decrease. It was also observed that the Nrf2 protein level increased significantly in the D.ET (P=0.020) and D.M.ET (P=0.009) training groups compared to the D group. Conclusion: Endurance training by increasing Nrf2 probably strengthens the antioxidant system and reduces oxidative stress. By reducing p53, it reduces the apoptosis of kidney tissue in diabetic and diabetic rats with morphine withdrawal syndrome.
