摘要：

MicroRNAs (miRNAs) represent a class of small, non-coding RNAs that negatively regulate gene expression via degradation or translational inhibition of their target mRNAs. Recent studies have identified that miR-145 is the most abundant miRNA in normal arteries and vascular smooth muscle cells (VSMCs), and its expression is significantly downregulated in dedifferentiated VSMCs and atherosclerotic arteries. miR-145 plays a critical role in modulating VSMC phenotype. Because phenotypic modulation of VSMCs is an initial cellular event in the development of atherosclerosis, miRNAs, and miR-145 in particular, may represent new therapeutic targets for atherosclerosis.
