| Outline of Final Research Achievements |
The purpose of this study was to determine whether in vivo heat treatment can improve an increase in body fat mass, a decrease in muscle mass and glucose tolerance in mice with sarcopenic obesity. According to the results, heat treatment had no effect on body weight, epididymal fat or lower-limb muscle mass in sarcopenic obesity. Fasting blood glucose levels did not change significantly with heat treatment. In contrast, heat treatment resulted in a decreased fasting plasma insulin level. Furthermore, we were able to identify three key enzymes from the glycolytic pathway upregulated by heat treatment, through comprehensive proteomic approaches. Our results indicate that heat treatment improves insulin resistance and the glycolytic pathway in a mice model with sarcopenic obesity. We suggested that heat treatment could be a potential therapeutic treatment for sarcopenic obesity-induced insulin resistance.
