Fig. 6. MRK-740 inhibits PRDM9 activity in cells.

Fig. 6

a MRK-740 but not MRK740-NC decreases PRDM9-dependent K4 trimethylation of exogenous histone H3. HEK293T cells were co-transfected with H3-GFP and PRDM9-FLAG and treated with compounds at indicated concentrations for 20 h. Mut denotes PRDM9 catalytic mutant (Y357S). First and last lanes are controls at 0 µM of compound. b The graph represents non-linear fit of H3K4me3 fluorescence intensities normalized to intensities of GFP (MRK-740 n = 10, 4 separate experiments, MRK-740-NC n = 4, 2 separate experiments). c MRK-740 and MRK-740-NC do not affect HEK293T cell growth up to 10 µM. Cells were treated with compounds for 1 day. Cell number was measured using IncuCyte™ ZOOM live cell imaging device. The results are mean ± sd, n = 3. Source data are provided as a Source Data file.
