Myogenin
Myogenesis is controlled by a group of transcriptional networks known as the myogenic regulatory factors (MRF). There are four MRFs involved in adult myogenesis, MyoD, Myf5, MRF4, and myogenin. Myogenin is expressed at high levels during the late stages of myoblast differentiation and myotube formation. In the current study after 8 weeks of consumption of the LC, myogenin level was significantly higher in LC compared to placebo, but within the group comparison did not show any changes in the LC group. In line with our study, an in vitro investigation showed that carnitine enhances myotubes differentiation by stimulating the expression of myogenin and skeletal muscle protein myosin heavy chain (Montesano et al.,
