表观遗传修饰与白血病

表观遗传修饰（epigenetic modification），如DNA甲基化、组蛋白乙酰化和甲基化、RNA相关性沉默与细胞生长、分化、凋亡、转化及肿瘤进展相关基因的转录密切相关。白血病的发生和发展与表观遗传修饰异常直接相关。本文综述细胞周期调节基因甲基化，组蛋白翻译后修饰异常及siRNA对白血病细胞的作用，为白血病治疗提供新策略。

Epigenetic Modification in Human Leukemia ——Editorial

Epigenetic modification, which involve DNA methylation, RNA-associated silencing and histone modification, is implicated in cell proliferation,differentiation, survival, apoptosis and malignant transformation. Some leukemogenesis has been shown to be aberrance of epigenetic modification. This paper discussed the potential causes of some of leukemias correlating with the methylation of cell cycle regulation genes, small interference RNA and modification abnormality of histone after translation. The study on epigenetic modification abnormality of leukemia cells provides a new strategy for treatment of leukemia.
