小泛素样分子化修饰在肺发育进程中的研究现状

Research status of small ubiquitin-like molecules modification in lung development

小泛素样分子(SUMO)通过与目标蛋白结合,调节多种细胞的功能。SUMO化修饰在胚胎发育中发挥重要作用,包括心脏、脑、肝等。参与肺发育和成熟的因子受到SUMO化修饰的调控,如缺氧诱导因子、CCAAT/增强子结合蛋白α、叉头盒蛋白M1、血管内皮生长因子、骨形态发生蛋白4等,从而影响其活性和稳定性。因此,靶标蛋白SUMO化修饰的状态是探究胎儿肺发育过程的关键。本文查阅近年来SUMO化介导肺发育的研究文献,并结合课题组多年的研究基础,对调控肺发育的因子及其SUMO化状态进行综述,为获得有效防治肺发育异常的药物研究提供思路。

Small ubiquitin-like molecules(SUMO) regulate the function of a variety of cells by binding to target proteins.SUMO modification plays an important role in embryonic development,including heart,brain,liver,etc.Factors involved in lung development and maturation are regulated by SUMO modification,such as hypoxia-inducible factor,CCAAT enhancer-binding protein α,forkhead box protein M1,vascular endothelial-derived growth factor,and bone morphogenetic protein 4,thus affecting their activities and stabilities.Therefore,the SUMO modification status of target protein is the key to explore the development process of fetal lung.In this paper,we reviewed the research literature of SUMO mediated lung development in recent years,and combined with the research basis of our research group for many years,reviewed the factors regulating lung development and the SUMO status,in order to provide ideas for the study of drugs for effective prevention and treatment of pulmonary dysplasia.
