However, under atrophy conditions, significantly less muscle mass is lost in either MuRF1 -/- or MAFbx -/- animals in comparison with control littermates [11]. Myostatin However, when muscle obtained from myostatin -/- animals was analyzed, it was shown to be larger as a result of an increase in the number of muscle fibers, and not as a result of hypertrophy. Therefore, it was thought that myostatin acts in a way that is distinct from the activation of atrophy or the inhibition of hypertrophy; that it simply blocks the proliferation of muscle precursors, thus decreasing muscle mass." . .
