Overall, these muscle subunit and metabolic changes are consistent with previous results on MyHC abundances (Picard et al., 2002) and also on m.Semitendinosus proteomic analyses (Chaze et al., 2008; Chaze et al., 2009) observed during the foetal stages in CH. The gene discussed is MYH6; the disease is cyclic hematopoiesis.
