慢性粒细胞白血病 (CML) 由 BCR-ABL1 诱发,伊马替尼可有效治疗多年,直到白血病细胞通过 BCR-ABL1 突变获得耐药性并进展为致命的 B 淋巴母细胞危象 (LBC)。尽管具有临床意义,但进展为 LBC 的机制尚不清楚。在这里,我们证明 LBC 而不是 CML 细胞表达 B 细胞特异性突变酶 AID。我们证明,CML 细胞中的 AID 表达通过肿瘤抑制基因和 DNA 修复基因的超突变促进整体遗传不稳定性。重要的是,我们的数据揭示了 AID 活性在导致伊马替尼耐药的 BCR-ABL1 突变获得中的致病作用,从而为耐药性和急变危机进展的快速发展提供了理论依据。
Chronic myeloid leukemia (CML) is induced by BCR-ABL1 and can be effectively treated for many years with Imatinib until leukemia cells acquire drug resistance through BCR-ABL1 mutations and progress into fatal B lymphoid blast crisis (LBC). Despite its clinical significance, the mechanism of progression into LBC is unknown. Here we show that LBC but not CML cells express the B cell-specific mutator enzyme AID. We demonstrate that AID expression in CML cells promotes overall genetic instability by hypermutation of tumor suppressor and DNA repair genes. Importantly, our data uncover a causative role of AID activity in the acquisition of BCR-ABL1 mutations leading to Imatinib-resistance, thus providing a rationale for the rapid development of drug resistance and blast crisis progression.
