Abstract
Aim: Apoptosis is a type of programmed death that is important in regulating the balance between cell death and tissue growth. Thus, the aim of this study is to investigate the effect of high-intensity interval training and curcumin supplement on apoptosis indicators such as TNF-α, NF-kB and Fas on hippocampal neurotoxicity caused by hydrogen peroxide consumption in male rats. Methods: This is an experimental research in which 50 adult male Wistar rats weighing 20 ± 200 g and aged 8 weeks were randomly divided into 5 equal groups of saline, hydrogen peroxide (H2O2, intense intermittent exercise + oxygenated water, curcumin supplement + hydrogen peroxide and intense intermittent exercise + Curcumin supplementation + hydrogen peroxide (n=10) were divided. H2O2 in the amount of 1 mmol per kg of body weight 3 times a week on even days and curcumin, 150 mg per kg of body weight per day, was used by gavage. The treadmill running program was performed for 8 weeks (five sessions per week with an intensity of 85-90 % of the maximum speed). At the end of the injection and training period, rats were extracted to evaluate changes in gene expression of hippocampal tissue. Data were analyzed using one-way ANOVA method at a significant level (α≥0.05). Results: The findings showed that hydrogen peroxide injection led to a significant increase in the expression of TNF-α, NF-κB, Fas genes (P=0.001). HIIT exercise and curcumin supplement each alone and together lead to decreasing changes in the expression of TNF-α, NF-κB, Fas (P=0.001), which shows the positive effect of exercise training and curcumin supplementation on the desired indicators. Conclusions: It seems so, exogenous injection of H2O2 has led to an increased the process of neuronal apoptosis. HIT exercises and curcumin supplement has been able to reduce the process of apoptosis.
