| Outline of Final Research Achievements |
Differentiation of myoblasts into myotubes in the presence of inflammatory cytokines was inhibited. In the absence of inflammatory cytokines, stimulation of α7 acetylcholine receptor by GTS21 increased myotube diameter and promoted expression of heavy chain myoglobin, but similar effects were not observed in the presence of inflammatory cytokines. In the presence of inflammatory cytokines it may be difficult to obtain a muscle hypertrophic effect by stimulation of GTS21. Previous published papers reported that muscle atrophy of mice was suppressed by administration of GTS 21 but the results of the present study are not due to direct action on muscle cells but the possibility that another mechanism of action may be involved.
