近年来,高度保守的Lin28 RNA结合蛋白已成为几种组织谱系中定义干性的因子。Lin28蛋白抑制let-7 microRNA并影响mRNA翻译,从而调节哺乳动物胚胎干细胞的自我更新。随后的发现表明,Lin28a和Lin28b在生物体生长和代谢、组织发育、体细胞重编程和癌症中也很重要。在这篇综述中,我们讨论了Lin28通路及其调控,概述了其在干细胞,组织发育和发病机制中的作用,并研究了重建哺乳动物生理学的后果。
In recent years, the highly conserved Lin28 RNA-binding proteins have emerged as factors that define stemness in several tissue lineages. Lin28 proteins repress let-7 microRNAs and influence mRNA translation, thereby regulating the self-renewal of mammalian embryonic stem cells. Subsequent discoveries revealed that Lin28a and Lin28b are also important in organismal growth and metabolism, tissue development, somatic reprogramming and cancer. In this Review, we discuss the Lin28 pathway and its regulation, outline its roles in stem cells, tissue development, and pathogenesis, and examine the ramifications for re-engineering mammalian physiology.
