| Outline of Final Research Achievements |
This study aimed to examine the underlying mechanism by which exercise improves insulin resistance from the perspective of redox homeostasis. In lean mice, but not in obese mice, administration of a xanthine oxidase (XO) inhibitor attenuated the activation of intracellular signal transduction and gene expression-related antioxidants following a single bout of exercise. Moreover, the XO inhibitor did not affect increased insulin sensitivity after exercise in obese mice. These results suggest that the effects of reactive oxygen species generation during exercise on intracellular signaling transduction and gene expression in skeletal muscle differ according to insulin resistance status.
