MicroRNAs (miRNA) are short nucleotide chains that act as inhibitors of gene expression. Specifically, miR-499 is a cardiac-abundant microRNA that can prevent cardiomyocyte apoptosis by targeting calcineurin-mediated activation of Drp1, an enzyme that normally results in fission of mitochondrial tubules into fragments. miR-499 may therefore have a key role to play following myocardial infarction, as […]
