Profiling of Chromatin States in a Human Cancer Cell Line

ABSTRACT: 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.

Acute depletion redefines the division of labor among DNA methyltransferases in methylating the human genome [MBD-seq]

Project description:Global patterns of DNA methylation, mediated by the DNA methyltransferases (DNMTs), are disrupted in all cancers by mechanisms that remain largely unknown, hampering their development as therapeutic targets. Combinatorial acute depltion of all DNMTs in a pluripotent human tumor cell line, followed by epigenome and transcriptome analysis, revealed DNMT functions in unprecedented detail. DNMT3B occupancy regulates methylation during differentiation, while an unexpected interplay was discovered in which DNMT1 and DNMT3B antithetically regulate methylation and hydroxymethylation in gene bodies, a finding confirmed in other cell types. DNMT3B mediated nonCpG methylation, while DNMT3L influenced the activity of DNMT3B toward nonCpG versus CpG site methylation. Taken together, these data reveal new functional targets of each DNMT suggesting that isoform selective inhibition would be therapeutically advantageous. NCCIT cells were transfected with siRNAs against DNMT3B and a no-target control. Genomic DNA was extracted, and subsequently applied to affinity MBD-bound magnetic beads (Ribomed) to enrich methylated DNA sequences.

Taken together, these data reveal new functional targets of each DNMT suggesting that isoform selective inhibition would be therapeutically advantageous. Overall, 27 samples were analyzed using the Infinium HumanMethylation450 BeadChip. 19 samples include NCCIT cells treated with various siRNAs targeting specific DNA methyltransferases. For the samples labeled biological replicate 1, NTC-1 serves as the control. Two additional biological replicates were analyzed for the siDNMT1, siDNMT3B, and si3B+3L condition; NTC-2 serves as the control for these samples. Six samples include HCT116 WT and various derivatives with alternative expression of DNMT1 and/or DNMT3B; WT serves as the control. Two samples include the undifferentiated (UD) and 7-day differentiated (DF) NCCIT cells; UD serves as the control.

Active DNA Demethylation by DNMT3A and DNMT3B - Mechanistic Aspect and In Vivo Evidence

Project description:The DNA methylation program is at the bottom layer of the epigenetic regulatory cascade of vertebrate development. While the methylation at C-5 position of the cytosine (C) residues on the vertebrate genomes is achieved through the catalytic activities of the DNA methyltransferases (DNMTs), the conversion of the methylated cytosine (5mC) could be accomplished by the combined actions of the TET enzyme and DNA repair. Interestingly, it has been found recently that the mouse and human DNMTs also possess active DNA demethylation activity in vitro in a Ca2+- and redox condition-dependent manner. We report here the study of tracking down the fate of the methyl group removed from 5mC on DNA during in vitro demethylation reaction by mouse de novo DNMTs, i.e. DNMT3A and DNMT3B. Remarkably, the methyl group becomes covalently linked to the catalytic cysteines utilized by the two de novo DNMTs in their DNA methylation reactions. Thus, the forward and reverse reactions of DNA methylations by the DNMTs may utilize the same cysteine residue(s) as the active site despite of their distinctive pathways. Secondly, we demonstrate that active DNA demethylation of a heavily methylated GFP reporter plasmid by ectopically expressed DNMT3A or DNMT3B occurs in vivo in transfected human HEK 293 cells in culture. Furthermore, the extent of DNA demethylation by the DNMTs in this cell-based system is affected by Ca2+ homeostasis as well as by mutation of their putative active cysteines. These findings substantiate the roles of the vertebrate DNMTs as double-edged swords in DNA methylation-demethylation in vitro as well as in a cellular context.

Genome-wide maps of chromatin remodeler SNF5 in human pluripotent cells.

Project description:We report the application of single-molecule-based sequencing technology for high-throughput profiling of SNF5 binding in human pluripotent embryonic carcinoma NCCIT and SNF5 overexpressed NCCIT cells. We generated genome-wide cSNF5 maps of NCCIT and SNF5 overexpressed NCCIT cells from chromatin immunoprecipitated DNA. SNF5 and OCT4 seem not to share their binding in OCT4 centered binding plot in control, while SNF5 overexpression directs SNF5 to OCT4 target genes. Examination of the relationship between SNF5 and OCT4 binding in control and SNF5 overexpressed cells.

Mammalian Dpy-30 regulates genomic H3K4 methylation and is essential for ES cell fate specification

Project description:H3K4 methylation is associated with active genes and, along with H3K27 methylation, is part of a bivalent chromatin mark that typifies poised developmental genes in ESCs. However, its functional roles in ESC maintenance and differentiation are not established. Here we show that mammalian Dpy-30, a core subunit of SET1/MLL complexes, biochemically modulates H3K4 methylation in vitro, and directly regulates chromosomal H3K4me3 throughout the mammalian genome. Depletion of Dpy-30 does not affect ESC self-renewal, but significantly alters the differentiation potential of ESCs, particularly along the neural lineage. The differentiation defect is accompanied by defects in gene induction and H3K4 methylation at key developmental loci. Our results provide strong experimental evidence for the hypothesis that H3K4 methylation is an essential functional component of the bivalent mark during activation of developmental genes in ESCs. Total RNAs from control or knockdown cells before and after RA-mediated differentiation were subjected to Illumina microarray analyses. ChIP-enriched DNA from mouse ES cells was analyzed by Solexa sequencing.

Extensive changes in DNA methylation are associated with expression of mutant huntingtin [ChIP-seq]

Project description:The earliest stages of HuntingtonM-bM-^@M-^Ys disease are marked by changes in gene expression that are caused in an indirect and poorly understood manner by polyglutamine expansions in the huntingtin protein (HTT). To explore the hypothesis DNA methylation may be altered in cells expressing mutated HTT, we use reduced-representation bisulfite sequencing (RRBS) to map sites of DNA methylation in cells carrying either wild-type or mutant HTT. We find that a large fraction of the genes that change in expression in the presence of mutant huntingtin demonstrate significant changes in DNA methylation. Regions with low CpG content, which have previously been shown to undergo methylation changes in response to neuronal activity, are disproportionately affected. Based on the sequence of regions that change in methylation, we identify AP-1 and SOX2 as transcriptional regulators associated with DNA methylation changes, and we confirm these hypotheses using genome-wide chromatin immunoprecipitation (ChIP-Seq). Our findings suggest new mechanisms for the effects of polyglutamine-expanded HTT. These results also raise important questions about the potential effects of changes in DNA methylation on neurogenesis and at later stages, cognitive decline in HuntingtonM-bM-^@M-^Ys patients.

De novo methylaton of the unmethylated K. phaffii genome by human DNA methyltransferases (DNMTs) [BiSulfite-seq]

Project description:We engineered combinatorial knock-in of human DNMTs in Komagataella phaffii, a yeast species lacking endogenous DNA methylation, to characterize methylation preferences and functional consequences of individual de-novo DNMTs as well as their combinations. Methylation preferences were determined through whole-genome bisulfite sequencing (WGBS) experiments. Effects of knock-in on gene expression were determined by RNA-seq. Measurements of genome-wide methylation produced by distinct de-novo DNMTs permitted determination of methylation preferences and aversions specific to individual DNMTs. Combining methylation and gene expression data provided insight about cellular response to the stress of DNA methylation and about the association between gene methylation patterns and changes in transcriptional output.
