a Effects on the proliferation of P31/FUJ cells by dual inhibition of MOZ/MORF KATs and DOT1L KMT. Proliferation of P31/FUJ cells in the presence of WM1119 and EPZ-5676 at the indicated concentrations was monitored for 21 days. b Differentiation of P31/FUJ cells after combinatorial inhibition of MOZ/MORF KAT and DOT1L KMT. Flow cytometry analysis for the CD11b antigen was performed on the P31/FUJ cells treated with various combinations of WM1119 and EPZ-5676 for 6 days. c Effects of combinatorial inhibition of MOZ/MORF KAT and DOT1L KMT on gene expression. RT-qPCR was performed on the P31/FUJ cells treated with only 100 nM WM1119 (WM), only 1 µM EPZ-5676 (EP), or a combination of both (WM & EP) (mean of two technical replicates). d Effects on the colony formation of human CD34 + cells and P31/FUJ cells by dual inhibition of MOZ/MORF KATs and DOT1L KMT (mean ± SD of technical replicates, n = 3). e Effects on the cell numbers of Human CD34 + cells and P31/FUJ cells by dual inhibition of MOZ/MORF KATs and DOT1L KMT (mean ± SD of three technical replicates). f Leukemia burden before and after the combination therapy using MOZ/MORF KATs and DOT1L KMT inhibitors. P31/FUJ human leukemia cells expressing LUC2Red were transplanted into sublethally irradiated SCID mice and subsequently administered with 35 mg/kg of WM119 and 20 mg/kg of EPZ-5676 three times a day (i.p.) for 2 weeks (mean ± SD of biological replicates, n ≥ 9). Welch’s t-test (two-sided) was performed on the indicated two-group comparison. Survival of transplanted recipient mice with or without MOZ/MORF KAT inhibitor treatment (the duration of drug administration is indicated in the graph). A log-rank (Mantel–Cox) test was performed. n.s.: P > 0.05. Source data are provided as a Source Data file.
