急性髓性白血病(AML)是一种以克隆性肿瘤造血前体细胞不受控制的增殖为特征的疾病。这导致正常造血功能的破坏和骨髓衰竭。过去的重大突破有助于我们理解AML细胞中的遗传失败和改变的生物学,这些生物学是疾病发生和发展的基础。现在人们认识到,不仅遗传,而且表观遗传改变在这一过程中同样重要。由于这些改变不改变DNA序列并且是可逆的,因此它们被认为是现在称为表观遗传疗法的最佳靶点。在这篇综述中,我们将讨论我们目前对正常表观遗传过程的理解,概述我们对AML表观遗传改变的了解,并讨论如何使用这些信息来改善目前对这种疾病的治疗。
Acute myeloid leukemia (AML) is a disease characterized by uncontrolled proliferation of clonal neoplastic hematopoietic precursor cells. This leads to the disruption of normal hematopoiesis and bone marrow failure. Major breakthroughs in the past have contributed to our understanding of the genetic failures and the changed biology in AML cells that underlie the initiation and progression of the disease. It is now recognized that not only genetic but also epigenetic alterations are similarly important in this process. Since these alterations do not change the DNA sequences and are pharmacologically reversible, they have been regarded as optimal targets for what is now known as epigenetic therapy. In this review, we will discuss our current understanding of normal epigenetic processes, outline our knowledge of epigenetic alterations in AML, and discuss how this information is being used to improve current therapy of this disease.
