(Submitter supplied) TET-family enzymes convert 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) in DNA. Tet1 and Tet2 are Oct4-regulated enzymes that together sustain 5hmC in mouse embryonic stem (ES) cells. ES cells depleted of Tet1 by RNAi show diminished expression of the Nodal antagonist Lefty1, and display hyperactive Nodal signalling and skewed differentiation into the endoderm-mesoderm lineage in embryoid bodies in vitro. more...

(Submitter supplied) How embryonic stem cells (ESC) commit to specific cell lineages and ultimately yield all cell types of a fully formed organism remains a major question. ESC differentiation is accompanied by large-scale histone and DNA modifications, but the relations between these two categories of epigenetic changes are not understood. Here we demonstrate the hierarchical interplay between the histone deacetylase, sirtuin 6 (Sirt6), which targets acetylated histone H3 at lysines 9 and 56 (H3K9ac and H3K56ac), and the Tet (Ten-eleven translocation) enzymes, which convert 5-methylcytosine (5mC) into 5-hydroxymethylcytosine (5hmC). more...

(Submitter supplied) Recent studies have analyzed the distribution and role of 5-hydroxymethylcytosin (5hmC) in Embryonic Stem Cells (ESC). However, DNA hydroxymethylation occurs also in differentiated cells and it is significantly deregulated in cancer. Here we mapped 5hmC genome-wide profile in pluripotent ES cells in comparison to embryonic and adult differentiated cells. Comparative analysis of 5hmC genomic distribution with respect to gene expression reveals that 5hmC is enriched on the gene body of genes expressed at medium/high level and on TSS of genes not expressed or expressed at low level independently from the cell type. more...

(Submitter supplied) Tet enzymes (Tet1/2/3) convert 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC). Tet1 and Tet2 mediate 5hmC generation in mouse embryonic stem cells (ESCs) and various embryonic and adult tissues. To investigate the effects of combined deficiency of Tet1 and Tet2 on pluripotency and development, we have generated Tet1 and Tet2 double knockout (DKO) ESCs and mice. DKO ESCs were depleted of 5hmC, but remained pluripotent with subtle defects in differentiation and changes in gene expression. more...

(Submitter supplied) DNA methylation of C5-cytosine (5mC) in the mammalian genome is a key epigenetic event that is critical for various cellular processes. However, how the genome-wide 5mC pattern is dynamically regulated remains a fundamental question in epigenetic biology.

(Submitter supplied) The TET family of FE(II) and 2-oxoglutarate-dependent enzymes (Tet1/2/3) promote DNA demethylation by converting 5-methylcytosine to 5-hydroxymethylcytosine (5hmC), which they further oxidize into 5-formylcytosine and 5-carboxylcytosine. Tet1 is robustly expressed in mouse embryonic stem cells (mESCs) and has been implicated in mESC maintenance. Here we demonstrate that, unlike genetic deletion, RNAi-mediated depletion of Tet1 in mESCs led to a significant reduction in 5hmC and loss of mESC identity. more...

(Submitter supplied) Loss of Tet1 expression causes global 5mC and 5hmC changes in stem and progenitor cells in mice and enhanced pro-B cell self-renewal, increased DNA damage and B-lymphomageneis. In this study we performed whole transciptome analysis using RNA-sequencing in purified long-term HSCs and MPPs. These results revealed that genes regulated byTet1 included Histones, DNA repair enzymes and B-lineage specific factors.

(Submitter supplied) Epigenetic pathways that regulate DNA methylation and chromatin modifications are frequently found to be dysregulated in human cancers. The TET methylcytosine dioxygenase 1 (TET1) enzyme is an important regulator of hydroxymethylcytosine (5hmC) in embryonic stem cells, neural progenitors,adult cells and reprogrammed cells. Decreased expression of TET proteins and loss of 5hmC has been reported in many tumors, suggesting a critical role for the maintenance of this epigenetic modification in normal cellular function. more...

(Submitter supplied) Recent studies have demonstrated that the Ten-eleven translocation (Tet) family proteins can enzymatically convert 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC). While 5mC has been studied extensively, little is known about the distribution and function of 5hmC. Here we present a genome-wide profile of 5hmC in mouse embryonic stem (ES) cells. A combined analysis of global 5hmC distribution and gene expression profile in wild-type and Tet1-depleted ES cells revealed suggests that 5hmC is enriched at both gene bodies of actively transcribed genes and extended promoter regions of Polycomb-repressed developmental regulators. more...
