Effects of miR-103a-3p on H9c2 cell viability. (A) Transfection efficiency of miR-103a-3p inhibitor and miR-103a-3p mimics detected via reverse transcription-quantitative polymerase chain reaction analysis. (B) MTT assays for the detection of cell viability. (C) Cell injury was determined via the leakage of LDH. NC, untreated H9c2 cells; H/R, H9c2 cells under H/R; mimic-Control, H9c2 cells transfected with miRNA mimic control; miR-103a-3p mimics, H9c2 cells transfected with miR-103a-3p mimic; miR-103a-3p mimics + H/R, H9c2 cells transfected with miR-103a-3p mimic and then H/R; miR-103a-3p inhibitor, H9c2 cells transfected with miRNA inhibitor; inhibitor-Control, H9c2 cells transfected with miRNA inhibitor control. All data are expressed as the mean ± standard deviation. *P<0.05, **P<0.01 and ***P<0.001, vs. NC; ###P<0.001, vs. H/R. miR, microRNA; NC, negative control; H/R, hypoxia/reoxygenation; LDH, lactate dehydrogenase.
