摘要
microRNAs(miRNAs)是一类含有20~22个核苷酸的非编码单链小分子RNA,发挥转录后水平负调控基因表达和翻译的作用,具有生物学功能多样性,可作为多种疾病诊断和预后重要分子标志。该文介绍了肌细胞特异性miRNAs,如miR-1、miR-133、miR-145、miR-206基因等染色体分布、序列、组织表达丰度、主要通路,并对肌细胞特异性miRNAs在气管平滑肌、血管平滑肌、心肌等细胞中的生物学效应研究进展进行综述。
miRNAs are a class of small non-coding, single stranded tiny molecule RNA (containing 20- 22 nucleotides) that negatively regulates gene expression and translation at post-translational level. They have diverse biological functions and can be used as significant molecule markers for disease diagnosis and prognosis. In this review, muscle-specific miRNAs were introduced, such as the distribution of chromosome, sequence, tissue expression abundance and main pathway of miR-1, miR-133, miR-145 and miR-206. Their biological effects in airway smooth muscle, vascular smooth muscle and cardiac muscle were also discussed.
