(Submitter supplied) Covalent modification of DNA distinguishes cellular identities and is crucial for regulating the pluripotency and differentiation of embryonic stem (ES) cells. The recent demonstration that 5-methylcytosine (5-mC) may be further modified to 5-hydroxymethylcytosine (5-hmC) in ES cells has revealed a novel regulatory paradigm to modulate the epigenetic landscape of pluripotency. To understand the role of 5-hmC in the epigenomic landscape of pluripotent cells, here we profile the genome-wide 5-hmC distribution and correlate it with the genomic profiles of 11 diverse histone modifications and six transcription factors in human ES cells. more...

(Submitter supplied) 5-Hydroxymethylcytosine (hmC) is particularly abundant in mammalian brains with yetto be revealed functions. Here, we present genome-wide and single-base-resolutionmaps of hmC and mC in the human brain. We demonstrated that hmCs increasemarkedly from the fetal to the adult stage, and in the adult brain, 13.4% of all CpGs arehighly hydroxymethylated with strong enrichment at genic regions and distal regulatoryelements. more...

(Submitter supplied) 5-hydroxymethylcytosines (5hmC) is particularly abundant in mammalian brain with little-known functions. Here we present the first genome-wide and single-base-resolution maps of 5hmC and 5mC in human brain by combined application of TAB-Seq and MethylC-Seq. We report that the majority of modified cytosines are hydroxymethylated in adult human brain, a significant proportion of which are highly-hydroxymethylated with enrichment in active genic regions and distal-regulatory elements. more...

(Submitter supplied) Genome-wide maps of cytosine methylation, cytosine hydroxylmethylation and small non coding RNAs in mouse ES cells and upon guided differentiation to mesoendoderm cells. Mouse embryonic stem cells (E14) were guided differentiated into mesoendoderm lineages by activin-A induction. cells in three time points (day0, day4 and day6) were collected. The genome-wide studies on three cell types were summerized as following: cytosine methylation data were generated using methylated DNA immunoprecipitation followed by sequencing (MeDIP-seq) and DNA digestion by methyl-sensitive restriction enzymes followed by sequencing (MRE-seq); DNA product for 5-hmC_ChIP-seq is generated by a selctive chemical labeling method (Nat. more...

(Submitter supplied) DNA methylation and hydroxymethylation have been implicated in normal development and differentiation, but our knowledge about the genome-wide distribution of 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) during cellular differentiation remains limited. Using in vitro model system of gradual differentiation of human embryonic stem (hES) cells into ventral midbrain-type neural precursor (NP) cells and terminally into dopamine (DA) neurons, we explored changes in 5mC or 5hmC patterns during lineage commitment. more...

(Submitter supplied) Hydroxymethylcytosine (5hmC) was recently found to be abundantly present in certain cell types including embryonic stem cells. The function of 5hmC is poorly understood. Here we have generated a genome-wide map of 5hmC in human embryonic stem cells (hESCs) by hydroxymethyl-DNA immunoprecipitation followed by massively parallel sequencing (hmeDIP-seq). We found that 5hmC is enriched over enhancers as well as gene bodies, suggesting a potential role of 5hmC in gene regulation. more...

(Submitter supplied) DNA methylation dynamics influence brain function and are altered in neurological disorders. 5-hydroxymethylcytosine (5-hmC), a DNA base derived from 5-methylcytosine (5mC) accounts for ~40% of modified cytosine in brain, and has been implicated in DNA methylation-related plasticity. Here we map 5-hmC genome-wide across three ages in mouse hippocampus and cerebellum, allowing assessment of its stability and dynamic regulation during postnatal neurodevelopment through adulthood. more...

(Submitter supplied) 5-methylcytosine (5-mC) can be oxidized to 5-hydroxymethylcytosine (5-hmC). Genome-wide profiling of 5-hmC thus far indicated 5-hmC may not only be an intermediate form of DNA demethylation but could also constitute an epigenetic mark per se. We describe a cost-effective and selective method to detect both the hydroxymethylation and methylation status of cytosines in more than 1.8 million MspI sites in the human genome. more...

(Submitter supplied) Murine and non-human primates (e.g. rhesus monkeys) represent excellent model systems to study human health and disease. However, use of these model systems for genomic studies is limited, particularly with array-based tools, as most have only been developed to survey the human genome. Here we present the optimization of a widely used human DNA methylation array, designed to detect 5-methylcytosine (5-mC), and show that non-human data generated using the optimized array reproducibly distinguishes tissue types within and between chimpanzee, rhesus, and mouse, with correlations near the human DNA level (R2 > 0.99). more...

(Submitter supplied) 5hmC and TET proteins have been implicated in stem cell biology and cancer, but information on the genome-wide distribution of 5hmC is limited. Here we describe two novel and specific approaches to profile the genomic localisation of 5hmC. The first approach, termed GLIB (GLucosylation, perIodate oxidation, Biotinylation) uses a combination of enzymatic and chemical steps to isolate DNA fragments containing as few as a single 5hmC. more...

(Submitter supplied) We describe the use of a novel DNA modification-dependent restriction endonuclease AbaSI coupled with sequencing (Aba-seq) to map high-resolution hydroxymethylome of mouse E14 embryonic stem cells. The specificity of AbaSI enables sensitive detection of 5hmC at low occupancy regions. Bioinformatic analysis suggests 5hmCs in genic regions closely follows the 5mC distribution. 5hmC is generally depleted in CpG islands and only enriched in a small set of repetitive elements. more...

(Submitter supplied) The generation of distinctive cell types that form different tissues and organs requires precise, temporal and spatial control of gene expression. This depends on specific cis-regulatory elements distributed in the non-coding DNA surrounding their target genes. Studies performed on mammalian embryonic stem cells and Drosophila embryos suggest that active enhancers form part of a defined chromatin landscape marked by histone H3 lysine 4 mono-methylation (H3K4me1) and histone H3 lysine 27 acetylation (H3K27ac). more...
