The change of myocardial enzyme activity in MI mice with miR-325-3p dysregulation. The adult male mice were randomly divided into the sham group, MI group, MI + agomiR-control group, MI + agomiR-325-3p group and MI + antagomiR-325-3p group. a The serum concentrations of LDH in different groups. b The serum concentration of CK in different groups. c The serum concentration of MDA in different groups. d The serum concentration of SOD in different groups. **P < 0.01 compared to the mice that received the sham operation, ^##P < 0.01 compared to MI mice. MI, myocardial infarction; agomiR-325-3p, miR-325-3p agomir; antagomiR-325-3p, miR-325-3p antagomir; agomiR-control, scrambled agomir or antagomir control; LDH, lactate dehydrogenase; CK, phosphocreatine kinase; SOD, superoxide dismutase; MDA, malondialdehyde
