Abstract

Background: Patients with diabetes mellitus are at high risk of antioxidants and in long-term vascular lesions. Therefore, the aim of the present study was to evaluate the effect of one course of aerobic exercise on the gene expression of angiopoietin-1 (ANGPT-1) and cardiac tissue oxidative status (TOS) in diabetic rats. Materials and Methods: 30 male Wistar rats were divided into 3 groups (n= 10) diabetic training, diabetic control and healthy control groups. Animals in diabetic groups were diabetic by intraperitoneal injection of streptozotocin. The exercise program consisted of 6 weeks of treadmill training. 24 hours after the last training session to evaluate the effect of exercise, cardiac tissue samples were extracted to measure gene expression of ANGPT-1 and total oxidative status. One-way ANOVA with statistical level (P<0.05) was used to compare the differences between groups. Results: The results showed that gene expression of ANGPT-1 and TOS were significantly increased in the diabetic training group compared to the diabetic control group (P= 0.001) but only in the ANGPT-1 there were no significant differences (P= 0.001) between two groups of diabetic control and healthy control (P>0.05). Conclusion: It seems that endurance training has a positive effect on the expression of ANGPT-1 gene and improves the overall antioxidant status of the heart tissue of diabetic rats and improve the diabetic heart.
