摘要Ikaros是淋巴细胞发育和增殖所必需的转录因子,在部分儿童急性淋巴细胞白血病(ALL)中表现为不同的缺失状态,其中以Ik6显性负相亚型过表达多见.Ikaros缺失是B祖细胞型ALL患者预后不良的一个独立危险因素.国外学者最近还确立了ALL的一种新亚型"BCR/ABL1-like ALL",同样以Ikaros缺失、预后不良为主要特征.由此推测,Ikaros对儿童ALL的诊断和治疗可能起着关键的作用.

abstractsIkaros is a transcriptional factor playing an essential role in lymphoid lineage development and differentiation. Ikaros gene deletions occur in some acute lymphoblastic leukemia (ALL) patients, and the most common type of abnormality is overexpression of dominant negative isoforms 6 (Ik6). Deletion of Ikaros gene has an independent association with a very poor outcome in B-cell-progenitor ALL. A new subtype of ALL characterized by the deletion of Ikaros and poor outcome has been identified by researchers, and named BCR/ABL1 like ALL.We can conclude that Ikaros may play an important role in the diagnosis and treatment of pediatric ALL.
