Abstract：
:We found that a transient rise in cGMP levels, which was closely associated with the Ca2+ influx, occurred concomitant with the onset of myoblast fusion. The Ca2+ channel blocker D600 decreased both the cell fusion and the normal rise in cGMP levels. In contrast, the Ca2+ ionophore A23187 transiently increased cGMP levels and induced precocious fusion. In addition, the cGMP analog 8-Br-cGMP induced precocious fusion as A23187 did. The guanylate cyclase inhibitor, methylene blue delayed the fusion in a dose-dependent manner without significantly affecting cell alignment, proliferation, or muscle-specific protein expression. Furthermore, methylene blue delayed the normal rise in cGMP levels, and the fusion block imposed by methylene blue was significantly recovered by 8-Br-cGMP. On the basis of our present findings, we suggest that a Ca2+ influx-dependent rise in cGMP levels is an important step in myoblast fusion.
