Background: Apoptosis is a type of programmed cell death in extracellular organisms. High-intensity interval training and curcumin can make some changes in this process. Objectives: This study aimed to investigate the role of intense interval training with curcumin supplementation on BAX and Bcl-2 proteins and caspase-3 enzyme activity in rats. Methods: In this study, 48 elderly rats were randomly divided into four groups: (1) control, (2) training, (3) curcumin, and (4) training + curcumin. Then, high-intensity interval training group rats ran on the treadmill for eight weeks, five sessions per week, for 30 - 50 min, and curcumin was fed to the supplement group at 25 mg/kg of body weight three times per week for eight weeks. Gene expression levels of BAX and Bcl-2 and myocardial caspase enzyme were measured in the heart tissue. The Shapiro-Wilk test, one-way ANOVA, and Tukey test were used for data analysis. Results: Curcumin consumption and intense interval training increased the expression of BAX (P = 0.001), Bcl-2 (P = 0.002), and caspase (P = 0.001). Besides, BAX, Bcl-2, and caspase genes expression significantly changed in the groups compared to the control group. The ratio of BAX to Bcl-2 in the curcumin group and interval training was significantly lower than the other groups. The Tukey post hoc test confirmed a significant difference between the groups and the control group. Conclusions: High-intensity interval training did not reduce BAX protein, but the training and curcumin supplementation increased Bcl-2 protein expression and neutralized the BAX effect. Curcumin supplementation combined with intense interval training resulted in synergy and reduced cell programming mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
