(a) miRNA-132 expression detected by real-time fluorescence quantitative PCR after extracting total RNA from mouse myocardium; (b) miRNA-132 expression detected by real-time fluorescence quantitative PCR after transfection of H₉C₂ cells with NC, miRNA-132 mimics, and miRNA-132 inhibitor; (c) H₂O₂ induced H₉C₂ cells to simulate HF model in vitro; (d) stability of H9C2 cells transfected with NC, miRNA-132 mimics, and miRNA-132 inhibitor measured by MTT assay. ^∗P < 0.05, versus sham group; ^∗P < 0.05, versus NC group; ^#P < 0.05, versus model group.
