DNA hypermethylation encroachment at CpG island borders in cancer is predisposed by H3K4 monomethylation [ChIP-Seq]
The crosstalk between H3K4 monomethylation and DNA methylation has been receiving little attention to date. We investigated a mouse model harboring a loss-of-function mutation of lysine methyltransferase 2D (KMT2D), which catalyzes the monomethylation of lysine 4 on histone H3. We performed H3K4me1 ChIP-seq in spleen B cells with the wild type (WT) KMT2D as well as heterozygous (HET) and homozygous (HOM) chr15: 98,835,228 A>T KMT2D mutation. Alongside, using WGBS, we performed genome-wide DNA methylation profiling in spleen B cells with the WT KMT2D as well as HET and HOM chr15: 98,835,228 A>T  KMT2D mutation. Overall design: Genome-wide analysis of H3K4me1 histone mark in mouse B cells with the wild type KMT2D, heterozygous Ile5482Asn KMT2D mutation and homozygous Ile5482Asn KMT2D mutation.
