Background: Transcription Factor EB (TFEB) and Transcription Factor E2F1 play an important role in metabolism. This study investigated the effect of exercise training and high-fat diet on the gene expression of these factors in the visceral adipose tissue of mice.
Materials and Methods: In the experimental study, 28 male mice (C57BL/6) were assigned into four groups included Control, High-Fat Diet (HFD), Exercise Training (ET), and High-Fat Diet with Exercise Training (HFD-ET). The subjects of HFD were fed a high-fat diet for 12 weeks. The mice of ET performed continuous endurance training on a treadmill for six weeks. The mice of HFD-ET had six weeks of endurance training in addition to having the HFD. The Real-Time–PCR methods were used to measure the gene expression of TFEB and E2F1.
Results: 1) The gene expression of TFEB was increased by HFD and ET (P<0.05). 2) The combination of HFD and ET had an increasing effect on TFEB (P=0.02); However, this effect was not higher than ET and HFD, separately (P>0.05). 3) HFD caused an increase in E2F1 (P=0.03). 4) Neither ET nor combined HFD and ET significantly increased the expression of E2F1 (P>0.05).
Conclusion: Continuous endurance training has a similar effect (no opposite effect) to the high-fat diet on gene expression of TFEB. Further, it could be thought that this exercise training may partly negate the increasing effect of the high-fat diet on E2F1 expression.
