RNA-seq profiling of bone marrow-derived alveolar macrophages, foetal-derived alveolar macrophages and foetal-derived Langerhans cells from the lungs of wildtype and Suz12 knockout mice

ABSTRACT: Macrophages are at the forefront of immune responses and their transcriptional programs are modified by their tissue environment and in response to immunological challenge. Post-translational modifications of histones, such as histone H3 lysine 27 tri-methylation (H3K27me3) by the polycomb repressive complex 2 (PRC2), are tightly associated with epigenetic regulation of gene expression. To explore whether H3K27me3 is involved in either the establishment or function of the mononuclear phagocyte system, we selectively deleted the SUZ12 gene in mice, a core component of PRC2. SUZ12 ablation induced a rapid loss of the alveolar macrophage networks under both steady state and inflammatory conditions. Ablation of SUZ12 abrogated the proliferation of these cells required for their self-renewal. This SuperSeries is composed of the four SubSeries listed below.

To explore whether H3K27me3 is involved in either the establishment or function of the mononuclear phagocyte system, we selectively deleted the SUZ12 gene in one-week old mice, a core component of PRC2. SUZ12 ablation induced a rapid loss of the alveolar macrophage networks under both steady state and inflammatory conditions. Ablation of SUZ12 abrogated the proliferation of these cells required for their self-renewal.

H3K27me3 Cut&Tag profiling of bone marrow-derived alveolar macrophages from wildtype and Suz12 knockout mice

To explore whether H3K27me3 is involved in either the establishment or function of the mononuclear phagocyte system, we selectively deleted the SUZ12 gene in mice, a core component of PRC2. Consistent with the the role of PRC2 in maintaining transcriptional repression, we found that the majority of top-ranked genes enriched for H3K27me3 in wild type alveolar macrophages were upregulated in SUZ12 knock-out alveolar macrophages.

Deletion of RING1A/B and loss of H2AK119ub1 affects PRC2 occupancy and H3K27me3 genome-wide

Project description: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. Here, using a de novo targeting assay in mouse embryonic stem cells we unexpectedly discover that PRC1-dependent H2AK119ub1 leads to the recruitment of PRC2 and H3K27me3 to effectively initiate a polycomb domain. Genetic ablation of catalytic subunit of the PRC1 complex (RINGA/B) and ChIP-seq analysis of PRC1 and PRC2 components confirmed genome-wide decreases in PRC2 occupancy and H3K27me3 levels at PRC target sites. This activity is restricted to variant PRC1 complexes and genetic ablation experiments reveal that targeting of the variant PCGF1/PRC1 complex by KDM2B to CpG islands is required for polycomb domain formation and normal development. Together these observations provide a surprising new PRC1-dependent logic for PRC2 occupancy and polycomb domain formation. RING1A-/-;RING1Bfl/fl ES cells were treated with 800M-BM-5M tamoxifen for 48hours and compared to untreated control cells by ChIP-seq for RING1B, SUZ12, EZH2 and H3K27me3.

H3K27me3 is maintained at a reduced level in Suz12(Bgal/Bgal) ESCs [RNA-Seq]

Project description: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. RNA-seq was performed in wild type and Suz12(Bgal/Bgal) ESCs, here used to demonstrate the coverage of the Suz12 gene in mRNA reads.

JAZF1-SUZ12 dysregulates PRC2 recruitment and gene expression during cell differentiation

Project description:Polycomb repressive complex 2 (PRC2) maintains repression of genes specific for other cell differentiation stages through methylation of histone H3 lysine 27 (H3K27me3) and is regulated by nascent RNA. In endometrial stromal sarcoma, the PRC2 subunit SUZ12 is often fused with the transcription factor JAZF1. How JAZF1-SUZ12 affects PRC2 function and cell differentiation are unknown. Here, we show that JAZF1-SUZ12 disrupts PRC2 recruitment, gene expression and cell differentiation. The loss of the SUZ12 N-terminus in the fusion protein disrupted interaction with JARID2, EPOP and PALI1 and prevented recruitment of PRC2 from RNA to chromatin. JAZF1-SUZ12 occupied PRC2 target genes in undifferentiated cells but relocated to JAZF1 target genes during cell differentiation, altering patterns of H3K27me3 and gene expression and disrupting cell differentiation. We then performed RNA-seq in primary human cells expreesing all proteins, showing that JAZF1-SUZ12 was promoting a specific set of genes upregulated in decidualisation, while blocking immune related genes. These results reveal the defects in PRC2 function and cell differentiation caused by the JAZF1-SUZ12 fusion protein, which may underlie its role in oncogenesis.

EZH2 inhibition results in genome-wide PRC2 redistribution in cancer cell models

Project description:Upon EZH2 inhibitor treatment, PRC2 components EZH2 and SUZ12 are redistributed across the genome towards a small number of genomic loci that are refractory to H3K27me3 loss. Focal PRC2 accumulation and H3K27me3 retention occur primarily at CpG islands and transcription start sites of genes, with enrichment at canonical PRC2 nucleation sites. EZH2 and SUZ12 are present at low levels at actively transcribed TSSs, and this signal is lost with EZH2 inhibition.
