ABSTRACT
The discovery of non-coding RNAs has expanded our understanding of how genetic features are linked to cellular function. The illumination of this so-called dark matter of the genome has revealed new categories of RNA with essential roles in the regulation of protein-coding genes and genome organization. In particular, microRNAs and long non-coding RNAs have emerged as important regulators of cardiovascular health and disease. In this Review, we summarize our current understanding of the mechanisms and functional roles of microRNAs and long non-coding RNAs in the regulation of lipid homeostasis, vascular biology and atherosclerosis. We discuss how interruption of non-coding RNA regulatory circuits influence lipoprotein metabolism in the liver and the circulation, as well as the effects of non-coding RNAs on inflammatory processes in the artery wall that contribute to atherosclerotic plaque formation. Finally, we highlight potential opportunities to harness non-coding RNAs as biomarkers and targeted therapeutics for atherosclerotic cardiovascular disease.
