Notch信号通路与慢性淋巴细胞白血病的研究进展

Notch Signal Pathway and Chronic Lymphocytic Leukemia——Review

慢性淋巴细胞白血病(chronic lymphocytic leukemia,CLL)是一种惰性B淋巴细胞肿瘤,临床病程异质性较大。Notch信号通路是进化上十分保守的一条信号通路,参与调控正常细胞的生存、增殖、分化、凋亡等生理过程。近年来,越来越多学者研究Notch信号通路与CLL的关系,发现CLL细胞中存在Notch分子高表达或突变,与患者预后相关,参与肿瘤细胞抗凋亡及耐药机制等等。本文就近年来CLL与Notch信号通路的研究进展作一综述,包括CLL细胞Notch分子表达水平,CLL细胞Notch分子抗凋亡和耐药,CLL细胞中Notch分子突变,Notch分子与CLL预后关系和Notch分子抑制剂应用前景等。

Chronic lymphocytic leukemia（ CLL）, an indolent B-cell malignancy, is characterized by heterogeneity of the clinical course. Notch signaling pathway is an evolutionarily conserved signaling pathway and involved in the normal regulation of cell survival, proliferation, differentiation, apoptosis and other physiological processes. In recent years, more and more researchers study the relationship between Notch signaling pathway and chronic lymphocytic leukemia and have found that Notch molecules present in CLL cells with high expression or mutation, which associated with the prognosis, anti-apoptosis, drug-resistance and so on. In this article, the recent advances of studies on CLL and Notch pathway, including the expression level of Notch molecules in CLL cells, the anti-apoptosis and drug-resistance of Notch molecules in CLL cells, the mutation of Notch molecules in CLL cells, the relation of Notch molecules with CLL prognosis and the application prospect of Notch molecule inhibitors are reviewed.
