Project description:In order to assess Tet1 binding, we first generated a Flag tagged Tet1 ES cells and then knocked out Dnmt3a in the [WT, Tet1-Flag] cells. By Tet1 ChIP and Flag ChIP, we showed that Tet1 binding was complementary to Dnmt3a. And Tet1 binding was not affected or slightly increased at majority of its targets.

Project description:In this study: (1) we characterized the Tet1 non-catalytic functions in the regulation of ESC gene expression programs by performing transcriptomic analysis of Tet1 wild type (WT), Tet1 catalytic mutant (Mut) and Tet1 knockout (KO) mouse ESCs by RNA-seq to identify differentially expressed genes. (2) We mapped the genome-wide occupancy of endogenously FLAG-tagged Tet1-WT and Tet1-Mut in ESCs by CUT&Tag using a specific antibody against FLAG. (3) We determined how the genome-wide occupancy of the epigenetic modifiers: Ezh2, Sin3a, Chd4 and the enrichment of histone marks: H3K27me3, H3K4me3 and H3K27ac, are affected in Tet1-KO ESCs versus Tet1-WT and Tet1-Mut by CUT&Tag or CUT&RUN. (4) We analyzed methylation levels and distribution in Tet1-WT, Tet1-Mut and Tet1-KO ESCs by WGBS, to confirm Tet1 non-catalytic targets with no differential methylation. (5) We explored whether Tet1 non-catalytic functions play a role in chromatin accessibility by performing ATAC-seq in Tet1-WT, Tet1-Mut and Tet1-KO ESCs.

Project description:The study investigates CTCF/cohesin binding and chromatin looping by ChIP-seq and Micro-C. By ChIP-seq, we determined the genome-wide binding profiles of CTCF and Smc1a cohesin subunit in a knock-in mouse ES cell line (wt-CTCF; clone C59) with endogenously tagged wild type CTCF (FLAG-Halo-mCTCF) and Rad21 (mRad21-SNAPf-V5), and compared them to the same ES line expressing a mutant CTCF (ΔRBR-CTCF; clone C59D2), where we replaced a previously described RNA binding region with a short linker (GDGAGLINS) followed by a 3xHA tag (N576_D611del::3xHA). By Micro-C, we compared nucleosome-resolution chromosome folding maps of the same ES cell lines C59 and C59D2 described above, to determine the effect of deleting CTCF RNA binding region on chromatin looping.

Project description: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. The extent to which individual Tet family members contribute to the genome-wide 5mC and 5hmC patterns and associated gene network remains largely unknown. Here we report genome-wide mapping of Tet1 and 5hmC in mESCs and reveal a mechanism of action by which Tet1 controls 5hmC and 5mC levels in mESCs. In combination with microarray and mRNA-seq expression profiling, we identify a comprehensive yet intricate gene network influenced by Tet1. We propose a model whereby Tet1 controls DNA methylation both by binding to CpG-rich regions to prevent unwanted DNA methyltransferase activity, and by converting the existing 5mC to 5hmC through its enzymatic activity. This Tet1-mediated antagonism of CpG methylation imparts differential maintenance of DNA methylation status at Tet1 target loci, thereby providing a new regulatory mechanism for establishing the epigenetic landscape of mESCs, which ultimately contributes to mESC differentiation and the onset of embryonic development. Tet1 protein was depleted in J1 or E14 mouse ES cells by siRNA or shRNA treatment. Total RNA was purified and used to determine the global gene transcription profiles by microarray assays. The Tet1-regulated genes were identified by comparing the gene expression profiles of control and Tet1-depleted ES cells.

Project description:Here we report both TET1-WT and catalytically dead mutant TET1 (TET1-MUT) directly interact with STAT5B in PDX2 B-ALL cells. To study the landscape of TET1 and STAT5B binding in whole genomic DNA and test if the STAT5B binding signal is affected by TET1, we conduct the ChIP-seq assay with flag antibody (TET1-WT, TET1-MUT) and STAT5B antibody (sgNS or sgTET1) respectively. The results showed that TET1 bound peaks overlap with STAT5B very well and the tag density of STAT5B on target genes decreases in TET1-impeded cells. We conclude that TET1 recruit STAT5B to the promoters of its target genes and further promote the target genes’ transcriptions.

Project description:We analyzed the genome-wide binding of Tet1 in control (shScr) and Tet1 knockdown (shTet1) mouse ES cells using two different Tet1 antibodies (Tet1-C and Tet1-N). Furthermore, we generated genome-wide mapping of hydroxymethyl cytosine (hmC) and methyl cytosine (mC). We find that hmC, in contrast to mC, is also found at transcription start sites (TSSs), and that there is a significant overlap between Tet1 binding and hmC positive regions. Surprisingly, our results also suggest, that Tet1 has a role in transcriptional repression. We showed that Tet1 associates with Sin3A co-repressor complex, and by performing ChIP-sequencing of Sin3A, we find co-localisation of Tet1 and Sin3a throughout the genome Examination of Tet1 and Sin3A binding as well as hmC and mC localization in mouse ES cells
