Genome wide mapping of Jarid2 and Suz12 binding sites in mouse ES cells before and after Jarid2 depletion

ABSTRACT: We analyzed the overlap in genome wide binding sites between Jarid2 and Suz12 in mouse ES cells and find that Jarid2 and Suz12 peaks have an high degree (90%) of overlap. Moreover we analyzed the effect of Jarid2 down regulation on genome wide Suz12 binding sites and found that Loss of Jarid2 lead to the loss of 70% of Suz12 binding sites and to a 10 Fold reduction in intensity for 90% of Suz12 binding sites. Overall, these results demonstrate that Jarid2 plays an essential role for Suz12 (PRC2 complex) association to DNA. Examination of two different proteins in two different cell lines

The Polycomb group (PcG) proteins have an important role in controlling the expression of genes essential for development, differentiation and maintenance of cell fates. The Polycomb repressive complex 2 (PRC2) is believed to regulate transcriptional repression by catalysing the di- and tri-methylation of lysine 27 on histone H3 (H3K27me2/3). At present, it is unknown how the PcG proteins are recruited to their target promoters in mammalian cells. Here we show that PRC2 forms a stable complex wi ...[more]

Jarid2, a Polycomb member and target of miR-155, regulates the fates of Th17 and Treg cells

Project description:Genome-wide analysis of Jarid2, Suz12, and c-Maf binding and H3K27me3 profiling in miR-155 KO and WT Th17 performed by ChIP-seq. We found that Jarid2 and c-Maf is differentially expressed in absence of miR-155 and they compete for binding to the Il22 promoter. We highlight targets of Jarid2 and Suz12 in miR-155 KO Th17 cells that are epigenetically silenced by increased H3K27me3 status. Furthermore, genome-wide analysis through Suz12 ChIP-exo in WT and Jarid2fl/fl;CD4cre Th17 reveals defects in PRC2 recruitment in abscence of Jarid2 that results in derepression of genes in Th17 cells. Thus, one main function of miR-155 is to curb epigenetic silencing by targeting Jarid2. Examination of Jarid2, Suz12, c-Maf binding and H3K27me3 changes in miR-155 KO and WT Th17.

Genome-wide mapping of H3K4me3 and of PHF8 and ZNF711 binding sites in SH-SY5Y cells

Project description:We analyzed the genome wide binding sites for the potential XLMR genes PHF8 and ZNF711 in the neuroblastoma cell line SH-SY5Y using antibodies specific for PHF8 and ZNF711 and correlated this with binding pattern of H3K4me3. The total number of peaks detected for PHF8 based on 9.8 million sequence reads, 9.6 million sequence reads for ZNF711 and 9.1 million sequence reads for H3K4me3 after IgG normalization were 17075, 1875 and 19534, respectively. Annotation of the peaks to genes using the hg18 genome database revealed 10039 genes positive for H3K4me3, 7682 were bound by PHF8 and 1103 genes were bound by ZNF711 within +/-1000bp from TSS. As former genome wide analysis of H3K4me3 revealed is this histone mark preferentially associated with transcription start sites. The analysis revealed that 82% of H3K4me3 positive genes are also positive for PHF8. In general, PHF8 either co-localizes or partly overlaps with regions positive for H3K4me3 and covers the putative TSS of the target genes. Examination of two different proteins and one histone modification in a human neuroblastoma cell line

SUZ12 immunoprecipitation followed by protein indentification via mass spectrometry (SUZ12 IP-MS) in mESCs of SUZ12 WT, delta exon 4, KO, and KO rescues with SUZ12-L and SUZ12-S

Project description:Suz12 exon 4 encodes 23 amino acids (aa 129–152 in SUZ12-L) that partially overlap with the WD-binding domain 1 (WDB1, 110–145). We reasoned that exon 4 skipping might alter the structure of SUZ12 and, possibly, PRC2 composition. To explore this possibility, we generated ESCs that lack the Suz12 exon 4 via CRISPR-Cas9–induced deletion. In addition, to rule out any biases due to the expression levels and/or SUZ12 epitope masking, we generated Suz12 knockout (KO) ESCs (herein, KO) in which Suz12 expression was subsequently rescued by re-introducing either the Suz12-L or Suz12-S mouse isoform fused to a triple-Flag tag under the regulation of a CAG promoter (KO+L/S; Figures S2H–S2K). We performed SUZ12 immunoprecipitation coupled with mass spectrometry (IP-MS) in the WT and ∆ex4 clones to compare their interactomes and with a flag antibody in the KO and rescue cell lines. As expected, no peptides corresponding to exon 4 were retrieved in ∆ex4 samples, while the rest of the sequence displayed similar coverage. Comparison of interactors in the two conditions revealed that SUZ12 binding to AEBP2 and JARID2 was strongly reduced in ∆ex4 cells with respect to WT cells, whereas SUZ12 binding to most core components or to PRC2.1-specific factors was unchanged or only slightly increased . These observations were confirmed by SUZ12 IP followed by Western blot (WB). Flag IP-MS in rescue cells confirmed that, while the long isoform was able to correctly form comparable amounts of both PRC2.1 and PRC2.2 subtypes, interaction of the SUZ12-S with PRC2.2-specific factors was drastically reduced.

Jarid2 regulates hematopoietic stem cell function by acting with Polycomb Repressive Complex 2

Project description:Polycomb Repressive Complex 2 (PRC2) has been shown to play a key role in hematopoietic stem and progenitor cell (HSPC) function. Analyses of mouse mutants harboring deletions of core components have implicated PRC2 in fine-tuning multiple pathways that instruct HSPC behavior, yet how PRC2 is targeted to specific genomic loci within HSPCs remains unknown. Here we use shRNA-mediated knockdown to survey the function of known PRC2 accessory factors in HSPCs by testing the competitive reconstitution capacity of transduced murine fetal liver cells. We find that similar to the phenotype observed upon depletion of core subunit Suz12, depleting Jarid2 enhances the competitive transplantation capacity of both fetal and adult, mouse and human HSPCs. Gene expression profiling revealed common Suz12 and Jarid2 target genes that are enriched for the H3K27me3 mark established by PRC2. These data implicate Jarid2 as an important component of PRC2 that has a central role in coordinating HSPC function. RNA-seq of jarid knockdown, suz knockdown and control from HSPC in 16 week old mice.
