Spinal cord abnormal autophagy and mitochondria energy metabolism are modified by swim training in SOD1-G93A mice.

ABSTRACT: Amyotrophic lateral sclerosis (ALS) may result from the dysfunctions of various mechanisms such as protein accumulation, mitophagy, and biogenesis of mitochondria. The purpose of the study was to evaluate the molecular mechanisms in ALS development and the impact of swim training on these processes. In the present study, an animal model of ALS, SOD1-G93A mice, was used with the wild-type mice as controls. Mice swam five times per week for 30 min. Mice were analyzed before ALS onset (70 days old), at ALS 1 disease onset (116 days old), and at the terminal stage of the disease ALS (130 days old), and compared with the corresponding ALS untrained groups and normalized to the wild-type group. Enzyme activity and protein content were analyzed in the spinal cord homogenates. The results show aut
