Abstract

Although the myogenic regulator MyoD is expressed in proliferating myoblasts, differentiation of these cells is limited to the G0 phase of the cell cycle. Forced expression of cyclin D1, but not cyclins A, B, or E, inhibited the ability of MyoD to transactivate muscle-specific genes and correlated with phosphorylation of MyoD. Transfection of myoblasts with cyclin-dependent kinase (Cdk) inhibitors p21 and p16 augmented muscle-specific gene expression in cells maintained in high concentrations of serum, suggesting that an active cyclin-Cdk complex suppresses MyoD function in proliferating cells.
