This article provides new information demonstrating that UCP3 plays a role in modulating energy and redox stress related signaling pathways in proliferative muscle myoblasts. The studies used both UCP3 whole body knockout (KO) myoblasts as well as a novel UCP3 conditional KO mouse generated as part of the current study. Collectively, these findings show that, despite low levels, UCP3 is a key modulator of energy metabolism and oxidative stress in undifferentiated muscle myoblasts.
