(Submitter supplied) Polycomb repressive complex 2 (PRC2) trimethylates lysine 27 of histone H3 (H3K27me3), which regulates gene expression and controls diverse biological transitions in development, embryonic stem cell (ESC) differentiation, and cancer. Here we show that Polycomb-like 3 (Pcl3) is a component of PRC2 that promotes H3K27 trimethylation in ESCs. Chromatin immunoprecipitation and sequencing (ChIP-seq) revealed that Pcl3 co-localizes and recruits Suz12 to CpG islands. more...

(Submitter supplied) Genome-wide analysis of REST and Polycomb binding in Rest-/- and Eed-/- mouse embryonic stem (mES) cells showed that Rest was required for PRC1 recruitment to a subset of Polycomb regulated neuronal genes. Furthermore, we found that PRC1 can be recruited to Rest binding sites independently of CpG islands and the H3K27Me3 mark., and that PRC2 was frequently increased around Rest binding sites located in CpG-rich regions in the Rest2/2 mES cells. more...

(Submitter supplied) PCL family protein Phf19/Pcl3 is one of the accessory components of the PRC2 core complex, and Phf19 is highly expressed in murine ES cells and an ES cell-like embryonic carcinoma cell line, F9 cells. Here we performed microarray analysis of embryonal carcinoma cell line F9 following Phf19 knockdown by shRNA. Knocking down Phf19/Pcl3 in F9 embryonic cells led to derepression of numerous PRC2 direct target genes.

Analysis of F9 embryonic carcinoma cells depleted for Phf19, a PRC2 associated protein. PRC2 regulates pluripotency, differentiation, and tumorigenesis by catalyzing histone H3 lysine 27 trimethylation. Results provide insight into the role of Phf19 in regulating PRC2 function.

(Submitter supplied) In total 8,736,191 reads from IP fraction and 9,958,984 reads from Wash fraction uniquely mapped to the mouse genome (mm9). Settings for enrichment analysis: maxSpacing=500; minHits=20; minPeakHits=6; minRatio=3. 4,701 regions have been identified as enriched in the IP fraction. In order to get a rough idea of false discovery rate (FDR), enrichment analysis using Wash fraction as test and IP fraction as control was performed, 15 regions was found. more...

(Submitter supplied) Polycomb group (PcG) proteins are highly conserved epigenetic transcriptional repressors important for the control of numerous developmental gene expression programs and have recently been implicated in the modulation of embryonic stem cell (ESC) identity. We identified the PcG protein PCL2 (polycomb-like 2) in a genome-wide screen for novel regulators of self-renewal and pluripotency and predicted that it would play an important role in mouse ESC fate determination. more...

(Submitter supplied) In embryonic stem (ES) cells, bivalent chromatin domains with overlapping repressive (H3 lysine 27 tri-methylation) and activating (H3 lysine 4 tri-methylation) histone modifications mark the promoters of more than 2000 genes. To gain insight into the structure and function of bivalent domains, we mapped key histone modifications and subunits of Polycomb repressive complexes 1 and 2 (PRC1 and PRC2) genomewide in human and mouse ES cells by chromatin immunoprecipitation followed by ultra high-throughput sequencing. more...

(Submitter supplied) The Polycomb repressive complex 2 (PRC2) mainly mediates transcriptional repression and has essential roles in various biological processes including the maintenance of cell identity and proper differentiation. Polycomb-like (PCL) proteins, such as PHF1, MTF2 and PHF19, are PRC2-associated factors that form sub-complexes with PRC2 core components, and have been proposed to modulate the enzymatic activity of PRC2 or the recruitment of PRC2 to specific genomic loci. more...

(Submitter supplied) The essential histone variant H2A.Z localises to both active and silent chromatin sites. In embryonic stem cells (ESCs), H2A.Z is also reported to co-localise with polycomb repressive complex 2 (PRC2) at developmentally silenced genes. The mechanism of H2A.Z targeting is not clear, but a role for the PRC2 component Suz12 has been suggested. Given this association, we wished to determine if polycomb functionally directs H2A.Z incorporation in ESCs. 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) Eed (embryonic ectoderm development) is a core component of the Polycomb Repressive Complex 2 (PRC2) which catalyzes the methylation of histone H3 lysine 27 (H3K27). Trimethylated H3K27 (H3K27me3) can act as a signal for PRC1 recruitment in the process of gene silencing and chromatin condensation. Previous studies with Eed KO ESCs revealed a failure to down-regulate a limited list of pluripotency factors in differentiating ESCs. more...

(Submitter supplied) The chromatin modifying activities inherent to polycomb repressive complexes PRC1 and PRC2 play an essential role in gene regulation, cellular differentiation, and development. However, the mechanisms by which these complexes recognize their target sites and function together to form repressive chromatin domains remain poorly understood. Recruitment of PRC1 to target sites has been proposed to occur through a hierarchical process, dependent on the prior nucleation of PRC2 and placement of H3K27me3. more...

(Submitter supplied) The histone lysine demethylase protein, KDM2B, associates with the PCGF1/PRC1 complex and binds to non-methylated DNA through its ZF-CxxC domain, providing a possible molecular link between CpG island elements and polycomb nucleation (Farcas et al., 2012, Wu et al., 2013). Here, a novel genetic system was designed in which PCGF1/PRC1 targeting could be disrupted in vivo through the ablation of KDM2B-mediated DNA binding. more...

(Submitter supplied) Suz12(Bgal/Bgal) ESCs express a truncated form of Suz12 fused to Beta-galactosidase. These cells maintain a reduced level of H3K27me3 despite this mutation to a core component of PRC2, unlike Eed-/- ESCs whose H3K27me3 is ablated. This data shows the concomitant changes in H3K4me3 levels in these cells.

(Submitter supplied) Polycomb Repressive Complex 2 (PRC2) catalyzes histone H3 lysine 27 tri-methylation, an epigenetic modification associated with gene repression. H3K27me3 is enriched at the promoters of a large cohort of developmental genes in embryonic stem cells (ESCs). Loss of H3K27me3 leads to a failure of ESCs to properly differentiate, which presents a major roadblock for dissecting the precise roles of PRC2 activity during lineage commitment. more...
