| Outline of Final Research Achievements |
Regulation of skeletal muscle protein metabolism by the glucocorticoid (GC) -glucocorticoid receptor (GR) axis plays an important role in individual-level energy substance control through skeletal muscle-liver-adipose tissue cooperation. In this study, we analyzed the role played by PGC1alpha4, a key factor of muscle hypertrophy due to muscle load, in this mechanism. Using skeletal muscle under forced expression of PGC1alpha4, skeletal muscle specific PGC1alpha4 transgenic mice administered with synthetic glucocorticoid, and mouse skeletal muscle with muscle hypertrophy induced by resistance exercise training, we identified gene candidate groups showing common expression and characteristic expression.
