Overexpression of microRNA-145 in atherosclerotic plaques from hypertensive patients

MicroRNAs (miRNAs) are endogenous, non-coding, short, single-stranded RNAs and represent a new class of gene regulators. Recent evidence supports a role for miRNAs in cardiovascular pathophysiology and atherosclerosis development. We have previously demonstrated that miR-145 is widely expressed in human atherosclerotic lesions and its downregulation has been correlated with vascular smooth muscle cell dedifferentiation, a cardinal step in the...
