摘要: 后发性白内障(posterior capsular opacity,PCO)是白内障最常见的术后并发症,其主要是由囊膜下残留晶状体上皮细胞(len epithelial cell,LEC)发生上皮-间质转化(epithelial-to-mesenehymal transition, EMT)形成纤维性PCO造成的。而转化生长因子-β(transforming growth factor-β,TGF-β)是导致EMT最重要的细胞因子。近年来研究发现小RNA在转录后水平调控EMT发挥重要作用。本文就不同小RNA对TGF-β通路不同信号转导分子,如TGF-βII型受体、Smad2/3、Smad4、Snail、甲基CpG结合蛋白2、基质金属蛋白酶及Skp2基因等的干扰作用,抑制LEC发生EMT,从而预防PCO的研究进展做一综述。

Abstract: Posterior capsular opacification (PCO) is the most common complication after cataract operation. It has been established that the major reason of PCO is epithelial-mesenchymal transition (EMT) of residual lens epithelial cells (LECs) which forming fabric PCO. TGF-β had been proved as the strongest inducer to EMT. Recently, the small non-coding RNA-dependent posttranscriptional regulation of genes was proposed to play an important role in cataract-associated EMT. This review  describes the research progress of small RNA interference regulating different TGF-β-singaling pathways,such as TGF-β antibody II, Smad2/3, Smad4, Snail, methy1 CpG binding protein 2, matrix metalloproteinases, and Skp2 gene, in preventing the process of lens EMT  and PCO.
