Control of myeloid differentiation and leukemia stem cell (LSC) self-renewal involves genetic and epigenetic regulators and mechanisms. Genetic regulation in leukemia has been highlighted as a novel way for maintaining the LSC program. Translocations of histone methyltransferases, such as the mixed-lineage leukemia (MLL) genes including Hoxa9, Myc, and Ikzf2, give rise to one of the most aggressive subtypes of acute myeloid leukemia (AML). Uncontrolled expansion of immature myeloid cells coupled with leukemia stem cell self-renewal and a block in differentiation are some of the characteristic traits of AML.
