The Acute Effect of Running Exercise on Liver Abca1 Gene Expression in Male Wistar Rats

Abstract

Objectives. ATP-binding cassette transporters transfer a variety of substrates across the lipid bilayers in an energy-dependent manner. ABCA1 is a member of this family, which plays a crucial role in plasma HDL-C metabolism. On the other hand, the short-term effects of exercise training are less studied. The aim of this study was the effects of a single bout of exercise on liver ABCA1 gene expression in the male Wistar rats. Methods. Twenty four male Wistar rats were housed in a standard environment and randomly divided into two Control (n = 12) and Experimental (n = 12) groups. The exercise included running on a treadmill for 120 min (18 m/min). Immediately, 2 and 24 hours after exercise, rats were anesthetized, and samples were taken from the adipose tissue and liver. Liver ABCA1 was assessed by RT-PCR. Results. The results showed that liver ABCA1 gene expression had significant elevation immediately, 2 and 24 hours after exercise (p < 0.05). Conclusion. The findings of this study proved that acute exercise can increase liver ABCA1 gene expression.
