Genomic DNA were extracted using antibodies for EPOP, H3K4me3, Elongin B, RNA Polymerase II S5, USP7 or H2Bub. RNA-Seq samples were prepared by isolating total RNA using Trizol, mRNA Isolation, heat fractionation, reverse transcription and second strand synthesis Libraries were constructed of 10-50 ng of DNA following Illumina's® protocol
