The effect of endurance exercise and rosehip extract supplementation on the expression of P53 and cytochrome C genes in male rat heart.

Considering the effect of apoptosis on cardiovascular disease, this study aimed to determine the combined effect of endurance exercise and rosehip extract supplementation on the expression of P53 and cytochrome C genes in the myocardium of male rats. A total of 35 male rats were randomly divided into five groups (n=7) as follows: endurance exercise+rosehip extract supplementation (Ex+Supp), endurance exercise (Ex), rosehip extract supplementation (Supp), six-month control (Con2), and three-month control (Con). The subjects in Ex+Supp and Ex groups performed endurance exercise (running on a treadmill at 24-33 m/min for 10-60 min) for 12 weeks, five times a week. Subjects in Ex+Supp and Supp groups consumed 1000 milligrams/ kilogram of rosehip extract for 12 weeks. Also, Con and Con2 groups did not receive any intervention. To RNA extraction and synthesis cDNA and evaluate the P53 and cytochrome C genes of the myocardium of rats, RT-PCR analysis was used. Neither endurance exercise nor rosehip alone nor together significantly affected the expression of cytochrome C and P53 genes in the heart muscle of male rats (>0.05). Also, endurance exercise (=0.001) and rosehip supplementation (=0.002) alone and in interaction (<0.01) had a significant effect on body weight, myocardium weight, and the ratio of myocardium weight to body weight in male rats. Twelve weeks of endurance exercise accompanied with rosehip extract did not significantly affect the expression of P53 and cytochrome C genes. Further studies are suggested to confirm these results.
