MicroRNAs and lipid metabolism

MicroRNAs have emerged as critical regulators of cholesterol metabolism and promising therapeutic targets for treating cardiometabolic disorders including atherosclerosis. Here, we discuss the recent findings in the field, highlighting the novel mechanisms by which miR-33 controls lipid metabolism and atherogenesis, and the identification of novel miRNAs that regulate LDL metabolism. Finally, we summarize the recent findings that identified miR-33 as an important noncoding RNA that controls cardiovascular homeostasis independent of its role in regulating lipid metabolism.
