title: DNMT3A: the DioNysian MonsTer of acute myeloid leukaemia.
abstract: In the mythology of Ancient Greece, there was often a creative tension between the opposing forces of the gods Apollo and Dionysius, the two sons of Zeus. The Apollonian force was considered to be rational and lifegiving, whilst Dionysian forces were chaotic and elemental. Acute myeloid leukaemia is characterised by the clash of these forces: the chaotic proliferation of immature myeloid cells in the bone marrow overcomes the normal, orderly production of healthy blood cells. DNMT3A mutations occur early in the leukaemogenic process and may even act as "founder" mutations - the first step in a pathway towards malignant transformation. As such, these mutations may represent a Dionysian agent of disorder, inciting the chaotic myeloid proliferation and arrest of differentiation which are hallmarks of AML. This review will focus on the role of DNMT3A mutations in leukaemia pathogenesis, their influence on prognosis, and the potential for therapeutic targeting.
