Background: Autophagy is associated with the degradation of intracellular organelles and, as a regulator of cellular homeostasis, can affect muscle atrophy. Therefore, this study aimed to examine ATG5, ATG7, and Beclin1 gene expression in the soleus muscle of an animal model of Parkinson following eight weeks of endurance training with branched-chain amino acids (BCAA) supplementation.
Methods: In this study, 25 male Wistar rats (weight = 180–200 gr and age = 12 weeks) were used. First, the rats were divided into five groups (n = 5): healthy control, Parkinson control, Parkinson + training, Parkinson + BCAA, and Parkinson + training + BCAA. Eight weeks of moderate-intensity endurance training were performed. After anesthetizing the rats, the soleus muscles were isolated; then, RNA extraction, cDNA synthesis, and real-time PCR were used for gene expression analysis. One-way analysis of variance with Tukey's post-hoc test was used to analyze the data (P ≤ 0.05).
Results: ATG5, ATG7, and Beclin1 gene expression in the soleus muscle of rats significantly increased after Parkinson's induction (P = 0.001). After both interventions, there was a significant decrease in the gene expression of ATG5, ATG7, and Beclin1 (P = 0.001), observed only in the endurance training with BCAA supplementation group.
Conclusion: Although endurance training and BCAA supplementation alone did not significantly affect ATG5, ATG7, and Beclin1 gene expression, combining both interventions caused a significant decrease, indicating the significant effect of using endurance training with BCAA supplementation for Parkinson's disease in rats.
