Cell 20111001 3

Transforming growth factor beta (TGF-β) signaling, mediated through the transcription factors Smad2 and Smad3 (Smad2/3), directs different responses in different cell types. Here we report that Smad3 co-occupies the genome with cell-type-specific master transcription factors. Thus, Smad3 occupies the genome with Oct4 in embryonic stem cells (ESCs), Myod1 in myotubes, and PU.1 in pro-B cells. We find that these master transcription factors are required for Smad3 occupancy and that TGF-β signaling ...[more]

Chip-seq of H3 in murine embryonic stem cells, myotubes and pro-B cells.

Project description:Nucleosome remodeling results in loss of histone occupancy. To gain insight into variations in H3 occupancy in different murine cell types, chromatin immunoprecipitation coupled with massive parallel sequencing (ChIP-seq) was performed to determine genome wide occupancy of H3 in ES cells, myotubes and pro-B cells. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. ChIP was performed using an antibody against total H3 in murine ES cells in normal culture conditions, murine ES cells treated with the TGF-beta inhibitor (SB431542, 10uM) for 24 hours, myotubes differentiated for 48 hours and pro-B cells under normal culture conditions.

Master Transcription Factors and Mediator Establish Super-Enhancers at Key Cell Identity Genes [ChIP-Seq]

Project description:The master transcription factors Oct4, Sox2 and Nanog bind enhancer elements and recruit the Mediator co-activator to activate much of the gene expression program of embryonic stem cells (ESCs). We report here that the ESC master transcription factors and Mediator form “super-enhancers” at most genes known to control the pluripotent state, including those encoding the master transcription factors themselves. These super-enhancers consist of extraordinarily large genomic domains occupied by exceptional amounts of Oct4, Sox2, Nanog, Klf4, Esrrb and Mediator. Super-enhancers stimulate considerably higher transcription than typical enhancers in vivo and in reporter vectors. Reduced levels of Oct4 or Mediator cause preferential loss of expression of super-enhancer-associated genes relative to other genes, suggesting how changes in gene expression programs might be accomplished during development. In other more differentiated cells, super-enhancers containing cell-type-specific master transcription factors are also found at genes that define cell identity. These results implicate super-enhancers in the control of mammalian cell identity and differentiation. ChIP-Seq and controls associated with Super-Enhancers in murine cell types

ChIP-Seq of TBP in Mouse Embryonic Stem Cells

Project description:The TATA binding protein (TBP) is a transcription factor that binds specifically to a DNA sequence called the TATA box upstream of the transcription start site. To gain insight into the genes occupied by TBP, chromatin immunoprecipitation coupled with massive parallel sequencing (ChIP-seq) was performed to determine the genome-wide binding targets. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. ChIP was performed using an antibody against TBP.

ChIP-Seq data for REST, MCAF1, Ring1b and H4K20me3 in mouse embryonic stem (ES) cells

Project description:Multiple protein complexes and histone marks have been implicated and/or associated with gene repression in ES cells. To gain insights into repressive complexes present at repressed genes and their associated chromatin state, we profiled REST, MCAF1, Ring1b and H4K20me3 in mouse ES cells. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. ChIP was performed using an antibody against REST, MCAF1, Ring1b and H4K20me3.

ChIP-seq of chromatin modifications and factors associated with transcriptionally active regions of the genome in mES cells

Project description:Post-translational modification of histones are coupled to transcription where certain modifications are indicative of an active or inactive region of the genome. Additionally, protein complexes can regulate the placement of nucleosomes across the genome and this influences the ability of DNA-binding proteins to interact with regions of the genome. The datasets presented here are ChIP-seq datasets for chromatin modifications associated with active or poised genes (H2Bub, H3K9,K14Ac and H3K4me3). Brg1 is a subunit of the SWI/SNF chromatin remodeling complex. An antibody specific to the chromatin modification or indicated factor was used to enrich for DNA fragments in murine embryonic stem cells. DNA was purified and prepared for Illumina/Solexa sequencing following their standard protocol.

The developmental potential of iPSCs is greatly influenced by the selection of the reprogramming factors

Project description:Induced pluripotent stem cells (iPSCs) are commonly generated by transduction of Oct4, Sox2, Klf4 and Myc (OSKM) into somatic cells. Though iPSCs are pluripotent, they frequently exhibit high variation in their quality as measured by chimera contribution and tetraploid (4n) complementation. Thus, improving the quality of iPSCs is an indispensable prerequisite for future iPSC-based therapy. Here we show that one major determinant for iPSCs quality is the combination of reprograming factor selected. Ectopic expression of Sall4, Nanog, Esrrb and Lin28 (SNEL) in MEFs efficiently generated high quality iPSCs as compared to other combinations of factors. SNEL-iPSCs produced approximately 5 times more efficiently M-bM-^@M-^\all-iPSCM-bM-^@M-^] mice compared to OSKM-iPSCs. While differentially methylated regions, transcript number of master regulators, establishment of ESC-specific super enhancers, and global aneuploidy were comparable between the lines, aberrant expression of 1,765 genes, trisomy of chromosome 8 and abnormal H2A.X deposition were frequently observed in poor quality OSK-iPSCs and OSKM-iPSCs.

ChIP-Seq of chromatin marks at distal enhancers in Mouse Embryonic Stem Cells and adult tissues.

Project description:Enhancers are enriched by histone H3 lysine 4 mono methylation (H3K4me1). To gain insight into the relation between enhancers and developmental state, chromatin immunoprecipitation coupled with massive parallel sequencing (ChIP-seq) was performed in several cell types to determine the genome-wide binding targets of H3K4me1 and several other possible enhancer associated modifications. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. A chromatin IP against histone H3 or whole cell extract was sequenced and used as the background to determine enrichment. ChIP was performed mainly using antibodies against the chromatin marks H3K4me1 and H3K27ac.

Pol II Ser7phospho ChIP-seq in mES cells

Project description:RNA Polymerase II transcribes protein-coding and many non-coding RNA genes in eukaryotes. The largest subunit of RNA Polymerase II, Rpb1, contains a hepta-peptide repeat on its C-terminal tail with three potential phosphorylation sites (Serine 2, Serine 5 and Serine 7). Mammalian Rpb1 contains 52 repeats. The phosphorylation events are catalyzed by specific protein kinases where the phosphorylation of specific residues is coupled to the transcription cycle. For example, the Cdk7 subunit of TFIIH phosphorylates both Serine 5 and Serine 7 during intiation and the Cdk9 subunit of P-TEFb phosphorylates Serine 2 during the transition into productive elongation. The dataset presented here is the genome-wide distribution of RNA Pol II with Serine 7 of the CTD phosphorylated in murine embryonic stem cells. This data, in addition to phospho-specific datasets generated in the same cell type in Rahl et al. Cell 2010 and Seila et al. Science 2008, represents the genome-wide distribution of multiple RNA Pol II isoforms in murine embryonic stem cells: total Pol II, hypophosphorylated CTD Pol II, Serine 2 phosphorylated CTD Pol II, Serine 5 phosphorylated CTD Pol II and Serine 7 phosphorylated CTD Pol II. An antibody specific to RNA Pol II Serine 7 phosphorylated CTD (gift of Dirk Eick; Chapman et al. Science 2008) was used to enrich for DNA fragments associated with this Pol II isoform in murine embryonic stem cells. DNA was purified and prepared for Illumina/Solexa sequencing following their standard protocol. This is a single dataset but together with datasets from Rahl et al. Cell 2010 and Seila et al. Science 2008, these datasets represent the genome-wide distribution of multiple RNA Pol II isoforms in murine embryonic stem cells: total Pol II, hypophosphorylated CTD Pol II, Serine 2 phosphorylated CTD Pol II, Serine 5 phosphorylated CTD Pol II and Serine 7 phosphorylated CTD Pol II.
