Endothelial miRNAs as Cellular Messengers in Cardiometabolic Diseases.

Metabolic syndrome is a clustering of risk factors that increases susceptibility to serious cardiometabolic complications, including type 2 diabetes (T2D) and myocardial infarction. Understanding the underlying mechanisms will advance the development of diagnostic and therapeutic approaches. A prominent feature of cardiometabolic diseases is endothelial dysfunction. Endothelial cell (EC) homeostasis and response to pathological stimuli are controlled by gene regulatory networks in which miRNAs play a critical role. Recently, miRNAs have been implicated as cell-cell messengers that can influence cellular function. This review investigates the known and potential roles for miRNA-based cell-cell communication in the control of cardiovascular health and explores the value of identifying miRNA biomarkers and developing therapeutics that harness or antagonize miRNA-based communication.
