Circ_0001206 regulates miR-665/CRKL axis to alleviate hypoxia/reoxygenation-induced cardiomyocyte injury in myocardial infarction.

ABSTRACT:

Aims

Myocardial infarction (MI) is a type of cardiovascular disease caused by myocardial necrosis. Growing evidences have suggested that circular RNAs (circRNAs) play crucial roles in cardiac hypoxia/reoxygenation (H/R)-induced injury of MI.

Methods and results

Hypoxia/reoxygenation model of H9C2 cells was established and circ_0001206 expression was detected via quantitative real-time polymerase chain reaction. Ribonuclease R (RNase R) and Actinomycin D (Act D) assays verified the stability. Cell counting kit-8 (CCK-8), western blot, TUNEL, and flow cytometry assays evaluated cell viability and cell apoptosis. RNA pull-down, RNA binding protein immunoprecipitation (RIP), and luciferase reporter assays explored the mechanisms underlying MI. All experimental data were presente
