In MLL1-rearranged AML (MLL1-r), the MLL1 fusion protein (MLL-FP) causes dysregulated expression of HOXA9, MEIS1, PBX3, MEF2C and CDK6 [ 1 , 2 ]. HOXA9 and its co-factor MEIS1 are leukemogenic in myeloid stem progenitor cells [ 3 , 4 , 5 ]. Additionally, in AML with mtNPM1 (NPM1c), MLL1 is the main oncogenic regulator of HOXA9, MEIS1 and FLT3, promoting self-renewal of myeloid progenitor cells [ 2 , 6 , 7 ]....
