THE RELEVANCE OF MICRORNAS IN VASCULAR AGING
ABSTRACT MicroRNAs (miRNAs) are short, single-stranded non-coding RNAs that control gene expression by annealing to complementary sequences in mRNAs. They are estimated to regulate at least one third of human transcripts and hence, manipulation of these miRNAs can profoundly affect the proteome and ultimately cellular phenotypes. A substantial amount of work has shed light on the crucial roles of miRNAs in diseases. miRNA expression profiles between normal and diseased tissues have identified miRNA signature patterns that correlate to disease development and progression. This review discusses some of the important miRNAs that are involved in endothelial cell senescence and dysfunction that contribute to the development and progression of cardiovascular diseases.
