MicroRNAs (miRs) are transcriptionally-regulated single-strand RNAs that depress protein expression through post-transcriptional mRNA silencing. A host of recent studies have established essential roles for miRs in cardiac development and cardiac health. Regulated myocardial miR expression is seen in a variety of cardiac syndromes, and serum miR levels are being evaluated as disease biomarkers. Manipulation of miR levels in mouse hearts using genetic techniques or engineered miR mimetics and antagonists is elucidating the roles of specific cardiac miRs in cardiac development, the cardiac response to injury or stress, and heart disease. Targeting of multiple factors within a single biological response pathway by a given miR has prompted development of small miR-targeting molecules that can be readily delivered and have sustained in vivo effects. These advances establish a foundation for novel diagnostics and new therapeutic approaches for myocardial infarction, cardiac hypertrophy, and heart failure.
