(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) 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. The TET family of 5mC hydroxylases, which convert 5mC to 5-hydroxymethylcytosine (5hmC), have provided a new potential mechanism for the dynamic regulation of DNA methylation. 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) 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) The TET proteins TET1, TET2 and TET3 constitute a new family of dioxygenases that utilize molecular oxygen and the cofactors Fe(II) and 2-oxoglutarate to convert 5-methylcytosine (5mC) to 5-hydroxy-methylcytosine (5hmC) and further oxidation products in DNA1-5. Here we show that Tet1 and Tet2 have distinct roles in regulating 5hmC deposition and gene expression in mouse embryonic stem cells (mESC). Tet1 depletion in mESC primarily diminishes 5hmC levels at transcription start sites (TSS), whereas Tet2 depletion is mostly associated with decreased 5hmC in gene bodies relative to TSS. 5hmC is enriched at exon start and end sites, especially in exons that are highly expressed, and is significantly decreased upon Tet2 knockdown at the boundaries of high-expressed exons that are selectively regulated by Tet2. In differentiating murine B cells, Tet2 deficiency is associated with selective exon exclusion in the gene encoding the transmembrane phosphatase CD45. Tet2 depletion is associated with increased 5hmC and decreased 5mC at promoters/ TSS regions, possibly because of the redundant activity of Tet1. Together, these data indicate a complex interplay between Tet1 and Tet2 in mESC, and show that loss-of-function of a single TET protein does not necessarily lead to loss of 5hmC and a corresponding gain of 5mC, as generally assumed. The relation between Tet2 loss-of-function and selective changes in exon expression could potentially explain the frequent occurrence of both TET2 loss-of-function mutations and mutations in proteins involved in pre-mRNA splicing in myeloid malignancies in humans.

(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) Leukemia Inhibitory Factor (LIF) plays an essential role in the maintenance of pluripotency of mouse embryonic stem cells (mESCs). LIF withdrawal induces mESC differentiation. To define noval pluripotent factors downstream of LIF signaling, cDNA microarray was used and seveal well-known pluripotent genes were found to respond to LIF withdrawal, including Klf4, Esrrb, Tbx3, and Prdm14.
