Genome-wide maps of H3K4me3, H3K4me1, H3K27ac, H3K9/K14ac, and H3K4ac in SW480 WT and DBC1 KO cells Overall design: To identify DBC1-regulated histone H3 modifications, we perfomed ChIP-seq analyses of H3K4me1, H3K4me3, H3K4ac, H3K9/K14ac, and H3K27ac in colon cancer cell line SW480 WT and DBC1 KO cells.
