If a signaling pathway promoting differentiation in myoblasts is constitutively activated, which consequence follows?

💡 Explanation

Constitutive activation of a differentiation pathway leads to premature differentiation because the increased signaling overcomes normal regulatory checkpoints, therefore resulting in accelerated muscle fiber formation rather than maintaining the undifferentiated state or other cellular dysfunctions.
