| Outline of Final Research Achievements |
The loss of muscle mass causes decreased mobility and metabolic diseases such as obesity and type 2 diabetes. Therefore, naturally occurring nutraceuticals, which maintain and increase skeletal muscle mass, have emerged as a promising strategy to prevent poor health outcomes as described above. I found that 5-hydroxy-7-methoxyflavones (5-OH-7MFs) from Kaemperia parviflora have enhancing effects on muscle differentiation and myotube size. The intracellular Ca2+ chelator (BAPTA-AM) inhibited the enhancing effects and suppressed 5-OH-7MFs-induced protein synthesis in myotube, suggesting that the intracellular Ca2+ is involved in 5-OH-7MFs-induced hypertrophy. Furthermore, 5-OH-7MFs tended to increase soleus muscle mass in young mice, but significantly increased soleus muscle mass and muscle fiber size in senescence accelerated mice 1 (SAMP1).
