ABSTRACT

Myocardial ischemia-reperfusion (I/R) injury is a leading cause of heart disease and death. Decreasing the detrimental effect of I/R remains an urgent issue in clinical practice. The present study examined the interaction of the anesthetics (sevoflurane and propofol), ADAM8, and microRNA (miR)-221-5p in myocardial tissue protection in the hypoxia-reoxygenation (H/R) model. H9C2 cells were cultured and subjected to H/R stimulation for further verifications in vitro. Reverse transcription-quantitative PCR or western blotting was performed to evaluate mRNA or protein expression levels. Cell Counting Kit-8, BrdU, and caspase-3 activity assays were performed to investigate cell viability, proliferation and apoptosis. A dual-luciferase reporter assay was performed to verify the association between miR-221-5p and ADAM8. Sevoflurane had greater pro tective effects on the life of cardiomyocytes with H/R injury compared with propofol by promoting cell viability, proliferation and inhibiting apoptosis. Concurrently, compared with propofol-treated H/R injured cardiomyocytes, the expression level of ADAM8 in sevoflurane-treated H/R injured cardiomyocytes was higher. In addition, overexpression of ADAM8 promoted the cell viability and proliferation of sevoflurane-treated cardiomyocytes with H/R injury but inhibited cell apoptosis, while the downregulation of miR-221-5p showed an opposite trend to that of ADAM8 overexpression. The present data provide evidence that sevoflurane can mediate the miR-221-5p/ADAM8 axis, playing a better protective role compared with propofol in cardiomyocytes with H/R injury.
