Characterization of mitochondrial respiratory complexes involved in the regulation of myoblast differentiation.

During myoblast differentiation, mitochondria undergo numerous changes that are necessary for the progression of the myogenic program. Notably, we previously showed that alteration in mitochondrial activity was able to control the expression of keys regulator of cell cycle withdrawal and terminal differentiation. Here, we assessed whether inhibition of one of the respiratory complexes was a key factor in the regulation of myogenic differentiation in C2C12 cells, and was associated with alteration in reactive oxygen species (ROS) production.
