Global loss of DNA methylation uncovers intronic enhancers in genes
We used HCT116 colorectal cancer cells with and without mutations in DNA methyltransferases (resulting in a 95% reduction in global DNA methylation levels) to study the relationship between DNA methylation, histone modifications, and gene expression. (The double knockout cell line is called DKO1) Overall design: Examination of DNA methylation, two histone modifications, RNA polymerase II ChIP-seq and RNA expression in two cell line (HCT116 and DKO1). One of relipates of HCT116 RNA P II ChIP-seq is from GSM970210. Histone modification data(H3K27ac, H3K4me3) of HCT116 are from GSM945304, GSE31755. Two replicates of RNA-seq data in HCT116 are from GSM1266733 and GSM1266734
