GATA6在肝脏发育中的作用及调控机制

摘要

GATA6(GATA binding protein 6)是GATA锌指转录因子家族成员之一,以其保守的结合基序(G/A)GATA(A/T)而得名.GATA家族在脊椎动物细胞命运决定与分化、增殖和迁移以及内胚层和中胚层来源的器官发育中具有重要作用.GATA6作为谱系特化因子、染色质重塑因子、多能性因子和"先锋因子",在内胚层肝脏谱系决定、肝脏特化、肝芽生长以及肝母细胞增殖分化等阶段发挥关键的调控作用.本文综述了GATA6在肝脏发育中的作用及其研究进展,以期为进一步研究GATA6等发育关键转录因子的功能及调控机制提供参考.%GATA binding protein 6 (GATA6) is a member of the GATA family of zinc-finger transcriptional regulators, whose names come from the conservative base sequence (G/A)GATA(A/T). The GATA families play key roles in cell fate determination, proliferation, migration, and organogenesis of endoderm- and mesoderm-derived organs in vertebrates. As a lineage-specific factor, a chromatin remodeling factor, a pluripotent factor and a pioneer factor, GATA6 is involved in var-ious stages of liver development, including endoderm liver-lineage determination, liver specification, hepatic bud outgrowth and hepatoblast differentiation. In this review, we summarize recent progress in the roles and regulatory mechanisms of GATA6 in liver development.
