Overexpression of microRNA-135b-5p attenuates acute myocardial infarction injury through its anti-oxidant and anti-apptotic properties

Abstract

Myocardial infarction (MI) remains the leading cause of morbidity and mortality due partly to the limited regenerative capacity of cardiomyocytes to replace cardiomyocyte lost due to apoptosis. Inhibiting cardiomyocyte apoptosis is recognized as an effective therapeutic approach for MI. MicroRNAs (miRNAs, miRs), which regulate target genes at the post-transcriptional level, play a significant role in the regulation of cardiovascular diseases such as MI. MicroRNA-135b (miR-135b) has a protective effect on cardiomyocytes. However, the role of miR-135b in cardiomyocyte apoptosis in infarct myocardium needs further clarification.
