| Outline of Final Research Achievements |
Alpha7 nicotinic acetylcholine receptors (a7 nAChRs) have been found in muscle during development and denervation. However, the physiological function of a7 nAChRs in muscle is still unclear. We hypothesized that the a7 nAChRs regulates the differentiation of skeletal muscle cells and investigated the impact of a7 nAChRs on C2C12 murine skeletal muscle cells stimulating with GTS21, agonist of a7 nAChRs.The diameter of myotubes at day 6 treated with GTS-21 were significantly wider than control group . The expression of MHC was relatively increased in GTS-21 treatment group at day 6 .The alpha7 nicotinic acetylcholine receptor agonist GTS-21 enhances skeletal muscle differentiation and hypertrophy in C2C12 myoblasts and myotubes.
