Muscle regulatory transcription factor MyoD regulates the expression of the pro-apoptotic Bcl2 family member PUMA by binding to the promoter region of PUMA. The increase in MyoD binding to the PUMA promoter as a consequence of culture in differentiation media (DM) is diminished in myoblasts silenced for MyoD expression. In myoblasts silenced for MyoD expression, p53 binding to the PUMA promoter is diminished in response
