微小RNA(microRNAs,miRNAs)是一类在转录后水平调控基因表达的小分子RNA(约22个核苷酸)。miRNA/mRNA碱基配对互补性引起mRNA衰变和随后的基因沉默。这些内源性基因表达抑制剂主要在癌症中描述,但最近令人兴奋的发现也证明了在心血管疾病(CVD)包括动脉粥样硬化中的关键作用。miRNAs控制内皮细胞(EC)、血管平滑肌细胞(VSMC)和巨噬细胞的功能,从而调节动脉粥样硬化的进展。miRNAs的表达受动脉粥样硬化各个阶段所涉及的不同刺激的调节,相反,miRNAs调节与斑块发展有关的几条途径,如胆固醇代谢。在本综述中,我们重点关注miRNAs在动脉粥样硬化中的重要性,并进一步讨论其作为CVD生物标志物和治疗靶点的潜在用途。
MicroRNAs (miRNAs) are small (~22nucleotide) sequences of RNA that regulate gene expression at posttranscriptional level. MiRNA/mRNA base pairing complementarity provokes mRNA decay and consequent gene silencing. These endogenous gene expression inhibitors were primarily described in cancer but recent exciting findings have also demonstrated a key role in cardiovascular diseases (CVDs) including atherosclerosis. MiRNAs controls endothelial cell (EC), vascular smooth muscle cell (VSMC) and macrophage functions, and thereby regulate the progression of atherosclerosis. MiRNAs expression is modulated by different stimuli involved in every stage of atherosclerosis and conversely miRNAs modulates several pathways implicated in plaque development such as cholesterol metabolism. In the present review, we focus on the importance of miRNAs in atherosclerosis and we further discuss their potential use as biomarkers and therapeutic targets in CVDs.
