3q21 和 3q26 之间的染色体倒位会导致高风险的急性髓系白血病 (AML)。在这里,我们确定了一种机制,通过该机制,GATA2远端造血增强子(G2DHE或-77-kb增强子)在inv(3)(q21;q26)倒位中与EVI1基因非常接近,从而导致白血病发生。我们通过创建重现 inv(3)(q21;q26) 等位基因的细菌人工染色体 (BAC) 转基因模型,研究了 G2DHE 对白血病发生的贡献。携带相连的 BAC 的转基因小鼠患上了白血病,并伴有 EVI1 过度表达,而在携带相同转基因但缺少 GATA2 增强子的小鼠中未检测到肿瘤形成。这些结果通过 EVI1 原癌基因的异常表达确立了严重白血病发病机制的机制基础。
Chromosomal inversion between 3q21 and 3q26 results in high-risk acute myeloid leukemia (AML). Here, we identified a mechanism whereby a GATA2 distal hematopoietic enhancer (G2DHE or −77-kb enhancer) is brought into close proximity to the EVI1 gene in inv(3)(q21;q26) inversions, leading to leukemogenesis. We examined the contribution of G2DHE to leukemogenesis by creating a bacterial artificial chromosome (BAC) transgenic model that recapitulates the inv(3)(q21;q26) allele. Transgenic mice harboring a linked BAC developed leukemia accompanied by EVI1 overexpression, neoplasia that was not detected in mice bearing the same transgene but missing the GATA2 enhancer. These results establish the mechanistic basis underlying the pathogenesis of a severe form of leukemia through aberrant expression of the EVI1 proto-oncogene.
