The bone marrow is responsible for producing an incredible number of cells daily in order to maintain blood homeostasis through a process called hematopoiesis. Hematopoiesis is a greatly demanding process and one entirely dependent on complex interactions between the hematopoietic stem cell (HSC) and its surrounding microenvironment. Zinc (Zn) is considered an important trace element, playing diverse roles in different tissues and cell types, and zinc finger proteins (ZNF) are proteins that use Zn as a structural cofactor. In this way, the ZNF structure is supported by a Zn that coordinates many possible combinations of cysteine and histidine, with the most common ZNF being of the CysHis (C2H2) type, which forms a family of transcriptional activators that play an important role in different cellular processes such as development, differentiation, and suppression, all of these being essential processes for an adequate hematopoiesis. This review aims to shed light on the relationship between ZNF and the regulation of the hematopoietic tissue. We include works with different designs, including both in vitro and in vivo studies, detailing how ZNF might regulate hematopoiesis.
骨髓每天负责产生大量的细胞,以通过称为造血的过程来维持血液内环境稳定。造血是一个要求极高的过程,完全依赖于造血干细胞(HSC)与其周围微环境之间的复杂相互作用。锌(Zn)被认为是一种重要的微量元素,在不同的组织和细胞类型中发挥着多种作用,锌指蛋白(ZNF)是使用 Zn 作为结构辅助因子的蛋白质。以这种方式,ZNF 结构由协调许多可能的半胱氨酸和组氨酸组合的 Zn 支持,最常见的 ZNF 是 CysHis(C2H2)类型,它形成了一类转录激活因子,在发育、分化和抑制等不同细胞过程中发挥重要作用,所有这些都是适当造血所必需的过程。本综述旨在阐明 ZNF 与造血组织调节之间的关系。我们包括了具有不同设计的工作,包括体外和体内研究,详细说明了 ZNF 如何调节造血。
