摘要

 IKAROS家族锌指转录因子1(IKZF1)基因编码IKAROS蛋白,是一种重要的锌指样转录因子,在B淋巴细 胞增殖、分化及功能维持过程中发挥着重要的调控作用。IKZF1基因被认为是一个临床相关的肿瘤抑制因子,IKZF1缺失 致IKAROS单倍体剂量不足或显性负相与急性B淋巴细胞白血病(B-ALL)的发生发展紧密相关。因此,研究IKZF1基因 可为B-ALL的危险度分层提供新的分子标志物,有助于B-ALL个体化治疗。

Abstract

 IKAROS family zinc finger 1 (IKZF1) gene encoding a zinc finger transcription factor IKAROS plays an important role in the regulation of B lymphoid cell differentiation and proliferation. IKZF1 is a clinical tumor suppressive factor. Deletion of IKZF1 results in either haploinsufficiency or dominating negative for IKAROS that contributes to the development of B-cell acute lymphoblastic leukemia (B-ALL), associated with an poor prognosis. Study of IKZF1 may lead to identifying new risk stratification molecular indicator for B-ALL for a better guidance to individualized therapy.
