Abstract

Aim: The aim of the present study was to investigate the effect of high-intensity interval training and ginger supplementation on poly ADP-ribose polymerase 1 (PARP-1) and sirtuin 1 (SIRT1) gene expression in male mice with nonalcoholic fatty liver disease.

Method: Twenty-five adult male Wistar rats, six weeks old and weighing 160±25 grams, were randomly selected and placed on a high-fat diet for 12 weeks to induce nonalcoholic fatty liver disease. The rats were then divided into five groups: healthy control, fatty liver control, exercise, ginger supplementation, and exercise + ginger supplementation. After confirmation of nonalcoholic fatty liver disease, ginger supplementation was administered daily and intense interval training was administered to the relevant groups for 8 weeks, 5 sessions per week. Real Time-PCR was used to measure PARP-1 and SIRT1 gene expression.

Results: The expression of the PARP-1 gene in the exercise, ginger supplement, and exercise and ginger supplement groups was significantly reduced compared to the fatty liver control group (P=0.001). The expression of this gene in the fatty liver control group was also significantly increased compared to the healthy control group (P=0.001). The expression of the SIRT1 gene was also significantly increased compared to the fatty liver control group in the exercise, ginger supplement, and exercise and ginger supplement groups (P=0.001). The expression of this gene in the fatty liver control group was also significantly reduced compared to the healthy control group (P=0.001). No significant difference was observed between the experimental groups (P>0.05).

Conclusion: High-intensity interval training combined with ginger supplementation resulted in decreased PARP-1 and increased SIRT1 in male rats with nonalcoholic fatty liver disease. These changes appear to be effective in improving the severity of the disease.
