Abstract Background: Myocardial infarction (MI) is known worldwide for its important disabling features, including myocarditis and cardiomyocyte apoptosis. It is believed that microRNA (miRNA) has a role in the cellular processes of apoptosis and myocarditis, and miR-219a-5p has been found to suppress the inflammatory response. However, unknown is the precise mechanism by which miR-219a-5p contributes to MI. Methods: We measured the expression of miR-219a-5p and evaluated its effects on target proteins, inflammatory factors, and apoptosis in a mouse model of MI. Echocardiography was utilized to examine the MI clinical index, and triphenyl tetrazolium chloride staining was More >
