KDM1A and leukemia: But HOXA9 transcription factor expression may also be controlled by other epigenetic modifiers such as (i) inhibitors of the epigenetic eraser H3K4 demethylase LSD1/KDM1A [71,72] like GSK2879552 [73] and ORY-1001 [74,75] that induce leukemic cell differentiation and are currently in clinical trials; (ii) inhibitors of the H3K9 methyltransferase G9A/KMT1C (UNC0648) [76] or inhibitors of the H3K27 methyltransferase EZH2 (GSK126, UNC1999, CPI-1205, EPZ005687, EPZ-6438/tazemetostat) [77,78,79,80,81,82] as two well described epigenetic writers associated with leukemia.
