Abstract: (1106 Views) |
Background: Exercise and diabetes have opposite effects on GLUT4 protein, but its mechanism has not been fully investigated. This study aimed to investigate the effect of six weeks of endurance training on protein levels of GLUT4 and HDAC5 in extensor digitorum longus (EDL) muscle in diabetic rats.
Materials and Methods: 32 male Wistar rats (weight: 245±9.4 g) were randomly divided into 4 groups: Control, exercise, diabetic, diabetic-exercise. At 8 weeks of age, diabetes was induced by streptozotocin. The endurance training was performed for 6 weeks. 24 hours after the last session, the mice were sacrificed and EDL muscle was extracted. The protein levels of GLUT4 and HDAC5 were measured using ELISA method. One-way ANOVA was used to analyze the data at a significant level of P<0.05.
Results: Results showed significant differences in GLUT4 levels between control and diabetic (P=0.0005), diabetic-exercise and diabetic (P=0.0005) and diabetic and exercise groups (P=0.0005). Also, the results showed that there was no significant difference in HDAC5 protein levels between control and exercise (P=0.138), diabetic-exercise and diabetic (P=0.229) and exercise and diabetic groups (P=0.306), and there was a significant difference between the other groups (P<0.05). Also, There was a non-significant inverse relationship between GLUT4 and HDAC5 protein levels (r=-0.169, P=0.354).
Conclusion: The positive effect of endurance training on GLUT4 protein levels was greater in the diabetic than in the healthy group. Although endurance training had a positive effect on GLUT4 and HDAC5 levels and effect on GLUT4 protein was greater and more significant. |
