Abstract :

MicroRNAs and heat shock proteins are important factors in heart function. However, the response of these factors to exercise in the heart tissue is unclear. Here, we evaluated the impact of endurance training on the expression of MIR-1 and HSP-60 genes in heart tissue of rats. In this study, 10 male Wistar rats were randomly divided into 2 groups control and endurance training. The aerobic exercise program included running on the treadmill at speed of 25 m min-1, 5 days a week for 12 weeks. After anesthesia, we performed an autopsy to collect the heart. The expression level of MIR-1 and HSP60 were measured by Real-Time PCR. An Independent t-test was used to determine significant changes (P<0.05). After the intervention period, the expression level of the MIR-1 gene showed a significant decrease in the aerobic exercise group thank in the control group (P=0.001). However, aerobic training had no significant effect on the expression level of HSP60 in the heart (P<0.05). It seems that twelve weeks of moderate-intensity aerobic exercise can probably improve heart function.
