Outline of Final Research Achievements |
Masticatory muscles have the potential to adapt their mass and fiber types to a wide range of functional demands, as observed in limb muscles. However, these molecular mechanisms are poorly understood. In this study, we analyzed the effects of bite-opening treatment (BO) on muscle phenotypes of mice masseter muscle. To examine hypertrophic effects of BO on masseter and soleus muscles as well as antagonistic action of dexamethasone (DEX), a glucocorticoid, against hypertrophy, we analyzed both muscle mass and fiber diameter of masseter, soleus muscles in BO and/or DEX-treated mice. These results suggest that differences in the sensitivity to DEX or in the mechanisms of DEX antagonism between masseter and soleus muscles.
