Abstract: Myocardial ischemia/reperfusion (I/R) causes serious threats to human life. Naringenin, a polyphenolic compound naturally occurring in citrus fruit, has cardioprotective effects against myocardial I/R injury. Besides, miR-24-3p is also reported to have cardioprotective effects. We intended to explore whether the cardioprotective effects of naringenin relate to miR-24-3p and its underlying mechanism. In this study, we used an in vivo rat myocardial I/R model and an in vitro cardiomyocyte H9c2 hypoxia/reoxygenation (H/R) model. Myocardial injury was detected by hematoxylin-eosin staining and ELISA for creatine kinase (CK), malondialdehyde (MDA), and lactate dehydrogenase (LDH). miR-24-3p and cell death inducing p53 target 1 (Cdip1) mRNA expressions were examined by RT-PCR. We find that naringenin pretreatment significantly relieves myocardial I/R injury, reduces LDH, CD, and MDA levels, and increases miR-24-3p expression. Furthermore, miR-24-3p alleviates myocardial I/R injury partially through regulating Cdip1. Moreover, naringenin protects myocardial I/R injury partially by regulating miR-24-3p to inhibit Cdip1 expression. In conclusion, our data suggest naringenin protects myocardial I/R injury partially through miR-24-3p/Cdip1 axis
