qRT-PCR analysis further demonstrated that the expression of hypertrophy-related markers, including natriuretic peptide A (Nppa), Nppb, and myosin heavy chain 7 (Myh7), was markedly elevated in the DCM group relative to the CON group, while all exercise modalities considerably suppressed their expression (Figure 3C–E). This evidence concerns the gene MYH7 and familial dilated cardiomyopathy.
