Research Abstract

(Aim) To clarify the role of PKC-delta on disuse muscle atrophy. (Method) We investigated muscle atrophy and signal transduction of hind-limb model in PKC-delta KO mice. (Result) In PKC-delta KO mice, weight of soleus muscle was lower than those in control mice. Muscle atrophy induced by hind-limb was similar between the groups. (Conclusion) Our result suggested that PKC-delta may contribute to the size of soleus muscle, while it may not affect on disuse muscle atrophy.
