The Effect of Aerobic Training and Eugenol Supplementation on the Brain-Derived Neurotrophic Factor and Phosphoinositide 3-Kinase Expression in the Skeletal Muscle of Male Rats Poisoned With Chlorpyrifos
Abstract
Background: Chlorpyrifos (CPF) is an insecticide and has a wide range of applications in the world. The purpose of this research was to investigate the effect of 4-week aerobic exercise and eugenol supplementation on the brain-derived neurotrophic factor/phosphoinositide 3-kinase (BDNF/PI3K) pathway on the skeletal muscle of male rats poisoned with CPF. Materials and Methods: Overall, 12-week-old female rats were used in this experimental research. The rats were randomly divided into 7 groups (8 rats in each group), including healthy control, toxic control, poison solvent, corn oil solvent, poisoned+eugenol, poisoned+aerobic exercise, and poisoned+aerobic exercise+eugenol. Moderate training in the range of 50%-60% VO2max, including 5 training sessions per week (treadmill). Poisoning was performed with CPF poison with a dose of 3 mg/kg. The dose of eugenol was determined to be 250 mg/kg. Finally, a one-way analysis of variance and Tukey’s post hoc test were employed to check the difference between groups. Results: The expression of PI3K and BDNF in the poisoned control group was lower than that in the healthy control group (P=0.049 and P=0.001, respectively). In addition, the expression of PI3K and BDNF was higher in the poisoned+eugenol+exercise group compared to the poisoned control group (P=0.009 and P=0.03, respectively). The corn solvent group also had a higher PI3K and BDNF expression in comparison to the poisoned control group (P=0.025 and P=0.01, respectively). Eventually, there was no significant difference among other groups. Conclusion: Exercise and eugenol increased PI3K and BDNF expression. It is thought that exercise and consumption of eugenol in poisoned rats reduces damage and improves muscle function and the BDNF/PI3K signaling pathway.
