Regulation of Promoter and Enhancer Histone Landscape by DNA Methylation in Embryonic Stem Cells (RRBS)

ABSTRACT: In this study, we mapped modification of lysine 4 and lysine 27 of histone H3 genome-wide in a series of mouse embryonic stem cells (mESCs) varying in DNA methylation levels based on knock-out and reconstitution of DNA methyltransferases (DNMTs). We extend previous studies showing cross-talk between DNA methylation and histone modifications by examining a breadth of histone modifications, causal relationships, and direct effects. Our data shows a causal regulation of H3K27me3 at gene promoters as well as H3K27ac and H3K27me3 at tissue-specific enhancers. We also identify isoform differences between DNMT family members. This study provides a comprehensive resource for the study of the complex interplay between DNA methylation and histone modification landscape.

Expression profiles in the complete absence of DNA methylation [Agilent-014868]

Project description:Using all three CpG DNA methyltransferases, Dnmt1, Dnmt3a and Dnmt3b deficient (TKO) mouse ES cells and TKO ntTS cells, we examined three histone modifications H3K4me2, H3K27me3 and H3K9me2, of promoter region in ES, TS and Flk1+ mesodermal cells with WT or TKO background by ChIP-chip analysis. Global profile analysis of gene expression and histone modification showed that the difference of profiles was mainly lineage dependent. Although the effects of DNA methylation loss in three lineages were modest, H3K27me3 is most sensitive to DNA methylation among three modifications. Interestingly, differentially expressed genes between WT and TKO cells were also lineage dependent and small number of genes was overlapped between lineages. Our further analysis showed that the profiles of H3K27me3 modifications were dynamically changed between lineages, especially in TS cells, and the pattern of H3K27me3 modification was defectively established by loss of DNA methylation. Our data suggest that DNA methylation contributes to lineage dependent expression regulation by collaborating with histone modification.

Epigenetic regulation of cell type-specific expression patterns in the human mammary epithelium [ChIP-Seq]

Project description:Here we describe the application of high-throughput sequencing technology for profiling histone and DNA methylation, and gene expression patterns of normal human mammary progenitor-enriched and luminal lineage-committed cells. We observed significant differences in histone H3 lysine 27 tri-methylation (H3K27me3) enrichment and DNA methylation of genes expressed in a cell type-specific manner, suggesting their regulation by epigenetic mechanisms and a dynamic interplay between the two processes that together define developmental potential. The technologies we developed and the epigenetically regulated genes we identified will accelerate the characterization of primary cell epigenomes and the dissection of human mammary epithelial lineage-commitment and luminal differentiation. Examination of histone H3K27me3 modifications in 2 cell types from 3 individuals and H3K4me3 modifications in 2 cell types from one individual sample.

Profiling of Chromatin States in a Human Cancer Cell Line

Project description:DNA methylation mediated by the combined action of three DNA methyltransferases, DNMT1, DNMT3A, and DNMT3B, is essential for mammalian development and is also a major contributor to transformation. To elucidate how DNA methylation is targeted, we map the genome-wide localization of all DNMTs and methylation, and examine relationships between these markers and histone modifications and nucleosome structure. Our findings reveal a strong link between DNA methylation/DNMTs and transcribed loci and that these marks exhibit both overlapping and unique localization patterns. Comparisons with the epigenome of embryonic stem cells demonstrate that DNMT binding is associated with transformation-associated changes in methylation. Taken together, this study sheds important new light on determinants of DNA methylation and how it may become disrupted in cancer cells.
