The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Despite rapid advances in cardiovascular research and therapeutic strategies, ischemic heart disease (IHD) remains the leading cause of mortality worldwide. MicroRNAs (miRNAs) are small, non-coding RNAs which post-transcriptionally regulate gene expression. In the last few years, miRNAs have emerged as key tools for the understanding of the pathophysiology of IHD, with potential uses as new biomarkers and therapeutic targets. Several studies report a regulatory role of miRNAs, with regard to fundamental components of IHD pathogenesis and progression, such as lipoprotein metabolism, atherogenesis, vascular calcification, platelet function, and angiogenesis. Due to their high stability in biofluids, circulating miRNAs have attracted attention as promising biomarkers of IHD, especially in cardiovascular risk prediction and the diagnosis of myocardial infarction. Furthermore, experimental studies have demonstrated the potential of miRNA-targeted therapy in improving hyperlipidaemia, atherosclerosis, and angiogenesis. In this review, the current knowledge on the role of miRNAs in IHD and translational perspectives of their use are discussed.
