MALAT1 and myocardial infarction: Several lncRNAs take part in acute myocardial infarction (eg, Novlnc6), heart failure (eg, Myosin Heavy Chain Associated RNA Transcript, Mhrt), control hypertrophy and apoptosis of cardiomyocytes (29), and the regulation of vascular growth and function (e.g., MALAT1) (13).
