Outline of Final Research Achievements |
In this study, we analyzed the molecular mechanism underlying improvement of skeletal muscle functions by bile acid. We revealed that bile acid receptor TGR5 promotes muscle hypertrophy and muscle cell differentiation. Furthermore, TGR5 KO mice exhibited muscular atrophy and weakness.Therefore, TGR5 may be a feasible target for maintaining muscle function in the elderly. We have already found several food compounds that can activate TGR5. These functional food compounds could contribute to improving the muscle function of elderly people.
