Assays were prepared using 10
7 cells of each cell line per condition. Chromatin was fragmented by sonication (
Bioruptor, Diagenode, Denville, NJ, USA) for 30 min (30-s pulses, 30-s pauses) and assays were carried out following the manufacturer's protocol (kch-mahigh-A16,
HighCell# ChIP Kit, Diagenode), using
anti-EVI1 (#2593, Cell Signaling Technology) or an equal amount of IgG isotype as negative control (#2729, Cell Signaling Technology). The amount of DNA was analyzed by real-time polymerase chain reactions using
SYBR Green-based assays (Applied Biosystems, Life Technologies, Foster City, CA, USA). The results were calculated using the ΔCt method. A genomic region of the
GAPDH gene was used as negative control (Diagenode). The corresponding human genome coordinates, EVI1-binding sites and primers designed for the assays are detailed in
Supplementary Table 5. Whole-genome ChIP data were obtained by hybridization to SurePrint G3 Human Promoter 1x1M microarrays (IRB Core Facility) and analyzed by MACS (version 2.0.9).
