| Outline of Final Research Achievements |
It is generally accepted that adiponectin is exclusively synthesized in and secrets from adipocyte, and stimulates glycolipid metabolism in skeletal muscle cells via circulating blood. Even though recent studies demonstrate the expression of adiponectin in skeletal muscle cells, there is no report regarding a physiological role of adiponectin that is expressed in skeletal muscle cells. The purpose of this study was to investigate the physiological role(s) of skeletal muscle cell-derived adiponectin in skeletal muscle differentiation. Knockdown of adiponectin and/or adiponectin receptor 1 suppressed myogenic differentiation, in part. Evidences of this study indicated skeletal muscle-derived adiponectin persist or stimulate myogenic differentiation to modulate its size in autocrine or paracrine manner. Skeletal muscle derived adiponectin may regulate glycolipid metabolism in skeletal muscle cells via modulating muscle mass.
