Disclosed are: (i) methods for identifying leukemia patients who (or leukemia cells that) do not exhibit an MLL-translocation, rearrangement or MLL-partial tandem duplication but who are nonetheless susceptible to treatment with DOT1L inhibitors; and (ii) methods for treating leukemia patients who (or inhibiting proliferation or inducing apoptosis of leukemia cells that) do not exhibit an MLL-translocation, rearrangement or MLL-partial tandem duplication with DOT1L inhibitors. The patients identified as susceptible and the patients (or cells) treated exhibit elevated expression of a HOX cluster gene or of a HOX cluster-associated gene. Elevated expression of such genes can be measured, e.g., by quantitating the relevant RNA and comparing it to that of a healthy individual (or cell) or to a predetermined standard or it can be inferred by determining whether the patient or cell possesses a mutation that is associated with elevated HOX cluster gene or HOX cluster associated gene expression and thereby inferring that the relevant expression with be elevated.
公开了(i) 用于鉴定那些(或白血病细胞)不表现出 MLL-易位、重排或 MLL 部分串联重复,但仍易受 DOT1L
抑制剂治疗的白血病患者的方法;(ii) 用 DOT1L
抑制剂治疗(或抑制不表现出 MLL-转位、重排或 MLL 部分串联重复的)白血病患者(或抑制白血病细胞增殖或诱导其凋亡)的方法。确定为易感的患者和接受治疗的患者(或细胞)表现出 HOX 簇
基因或 HOX 簇相关
基因的表达升高。此类
基因表达的升高可以测量,例如通过量化相关 RNA 并将其与健康个体(或细胞)的 RNA 或预定标准进行比较,或者通过确定患者或细胞是否具有与 HOX 簇
基因或 HOX 簇相关
基因表达升高有关的突变,从而推断出相关表达升高。
