The expression of miR-133a-3p and CTGF in cardiac muscle.

(A) miR-133a-3p mRNA expression in the heart (n = 3). (B) Western blotting results of CTGF protein in heart tissues (n = 3). (C) Western blot images of CTGF protein in infarct area and non-infarct area in different groups (n = 3). The values are presented as the mean ± SEM. SE, S+ exercise group; S, sham group; MI, myocardial infarct group; ME, MI+ exercise group. *P<0.05, **P<0.01.
