Advances in epigenetics and treatment of childhood acute myeloid leukemia / 国际儿科学杂志

ABSTRACT

Epigenetic alterations include chromosome translocation, polycomb function and non-coding RNA abnormalities, and etc.A study on genome of childhood acute myeloid leukemia(AML)in children has shown that these abnormalities play an important role in the pathogenesis of AML, and epigenetic heterogeneity is associated with poor prognosis and relapse of AML.Presently, the overall survival(OS)for AML in children has been improved, but for the refractory/relapsed acute myeloid leukemia(r/r AML), the prognosis or curative effect remains poor.The curative effect is expected to be improved by epigenetics related therapies.A large number of studies have found that the epigenetic abnormalities of AML in children are different from those in adults.Some drugs targeting epigenetic alternations, such as DNA methyltransferase inhibitor and IDH inhibitor, have been used to treat AML in children.This paper aims to review the epigenetic regulation abnormalities in children with AML and the progress in relevant clinical applications.
