| Outline of Final Research Achievements |
The purpose of this study is to find myokines secreted by skeletal muscle cells and elucidates their physiological roles. Conditional cell culture media of C2C12 myotubes were provided to mass analysis after contraction to identify new myokines. mRNA was isolated from the C2C12 myotubes after contraction and also provided to DNA micro array analysis. As a result, we had around 40 candidates of novel myokines. Then, each candidate molecule was knocked down in skeletal muscle-specific manner in drosophila. We observed shorten life span in myokine A knocked down drosophila. On the other hand, we observed prolonged life span in myokine B knocked down drosophila. Next, we generated skeletal muscle specific myokine A over expression mice. The transgenic mice had higher glucose metabolism rate and better result of glucose tolerance test compared to wild type mice.
