Multinucleated myotubes containing large numbers of striated myofibrils and large numbers of longitudinally-oriented 10-nm filaments were treated with the cocarcinogen phorbol-12-myristate-13-acetate (PMA) for 24, 48 or 72 hours. The inhibitory effects of PMA on the accumulation of myofibrils was evident within 24 hours, and by 72 hours virtually all striated myofibrils had disappeared. In contrast, the density of the 10-nm filaments was greatly enhanced in these myofibril-depleted myotubes. These effects were not due to a generalized cytotoxicity, for PMA stimulated the replication of the presumptive myoblasts and fibroblasts present in these cultures. 24 hours after removing the PMA, these myotubes assembled a new set of striated myofibrils and the density of 10-nm filaments diminished proportionately.
