Isoflurane Alleviates Myocardial Injury Induced by Hypoxia/Reoxygenation by Regulating miR-18a-5p
Abstract The protective effect and mechanism of isoflurane on myocardial injury was investigated by constructing in vitro hypoxia/reoxygenation (HR) cell model. HR cell models were established in vitro and treated with isoflurane (ISO). qRT-PCR was used to detect the relative expression of miR-18a-5p. CCK-8 kit and flow cytometry were performed to evaluate cell proliferation and apoptosis. The myocardial injury related markers, such as Cκ-MB, cTnI and LDH were detected by ELISA. Luciferase reporter gene assay was used to verify the interaction between miR-18a-5p and target genes. The expression of miR-18a-5p was significantly increased in hypoxic cardiomyocytes compared with control group (P < 0.001). Meanwhile, cardiomyocytes in the HR group showed inhibition of proliferation, a significant increase in cell apoptosis and in myocardial injury indicators, such as Cκ-MB, cTnI and LDH (P < 0.001). However, 1% ISO treatment alleviated myocardial cell injury induced by HR. Transfection of miR-18a-5p under ISO reduced the protective effect of 1% ISO against myocardial cell damage. Luciferase report gene assay confirmed that CCND2 might be the target gene of miR-18a-5p. In the in vitro cell model of myocardium, ISO alleviated cardiomyocyte injury caused by hypoxia/reoxygenation by down-regulating the expression of miR-18a-5p..
