Effects of miR‑103a‑3p on the autophagy and apoptosis of cardiomyocytes by regulating Atg5.

ABSTRACT: Autophagy and apoptosis are associated with cardiovascular diseases. Emerging evidence shows that microRNAs (miRs) are critical in the development of pathological processes underlying cardiovascular diseases by regulating the induction of apoptosis and autophagy. The present study aimed to investigate the role of miR‑103a‑3p in cardiomyocyte injury through autophagy and apoptosis. H9c2 cells were cultured under hypoxia and reoxygenation (H/R) conditions and were used to mimic cells under ischemia. The transfection of cells with miR‑103a‑3p (mimics and inhibitors) was performed to examine its function in cardiomyocytes. The expression levels of miR‑103a‑3p were evaluated by reverse transcription‑quantitative polymerase chain reaction analysis. Cell viability was determined using an MTT assa
