to investigate whether the normal decline in expression of vimentin and beta- , gamma-actins was coupled to withdrawal of proliferating myoblasts from the cell cycle or was a direct consequence of terminal differentiation , expression of the mrnas encoding the actin microfilaments and intermediate filaments was examined in differentiation-defective c2 myoblasts bearing oncogenic ras genes .
