Inhibition of miR-15 alleviated myocardial cell injury induced by coxsackievirus B3 (CVB3). H9c2 cells were transfected with miR-15 inhibitor or inhibitor-NC for 24 h, and then infected with CVB3 for another 24 h. a – Expression of miR-15 was determined using quantitative real-time PCR and normalized to U6 expression. b through d – Lactate dehydrogenase (b), creatine kinase-MB (c), and cTn-I (d) levels in the supernatants of cell lysates were determined using a fully automatic biochemical analyzer. *p < 0.05 versus the control group, #p < 0.05 versus the CVB3 group
