Arbitrary concentrations (mean+sem) of MyoD, Myf5 and Myogenin mRNA in the <i>B. femoris</i> muscles of <i>Mstn</i>(−/−) and wild-type mice during seven days of unloading and seven days of reloading (n = 6 per genotype and day).
<p>Asterisks denote differences between genotypes on days shown (*<i>P</i><0.05, **<i>P</i><0.01 and ***<i>P</i><0.001). Unlike letters denote significant differences (<i>P</i><0.05) across days (independent of genotype).</p
