| Outline of Final Research Achievements |
Sarcopenia is an aging-related debilitating condition which is characterized by progressive loss of skeletal muscle mass and strength. The mechanism of sarcopenia is not elucidated and the treatment has not been established. We examined the involvement of inflammation in inducing muscle atrophy and how this involvement was affected by HMB (a metabolite of leucine), vitamin D and TJ-41 (a traditional herbal medicine). In tail suspended mice, which is a mouse model bearing muscle atrophy, HMB and vitamin D inhibited muscle atrophy, expression of atrophy-related genes, and elevation of the serum interleukin-6 level. TJ-41 ameliorated reactive oxygen-induced damage in myoblasts by inhibiting inflammation. We conclude that anti-inflammatory effects of HMB, vitamin D and TJ-41 might be therapeutic to sarcopenia.
