Myostatin increases (A) col1α2 expression and (B) procollagen I content of primary skeletal muscle myotubes. (A) RT-qPCR: Myostatin increases the expression of col1α2 normalized to β2m in a dose-dependant fashion. Values are means ± SE. *Significantly different from the 0 ng/mL group at P < 0.05. #Significantly different from the 10ng/mL group at P < 0.05. (B) Immunoblot: Myostatin increases the procollagen I protein content of myotubes in a dose-dependant fashion. β-tubulin is shown as a loading control.
