ABSTRACT Introduction: RIP140 (Receptor Interacting Protein) is involved in the regulation of oncogenic signaling pathways and in the development of breast and colon cancers. The aim of the study was to analyze the expression of RIP140 and its partner LCoR in cervical cancers, to decipher their relationship with histone protein modifications and to identify a potential link with patient survival. Methods: Immunohistochemical analyses were carried out to quantify RIP140 and LCoR expression in formalin-fixed paraffin-embedded tissue sections cervical cancer samples. -
Automethylation of PRC2 Promotes H3K27 Methylation and Is Impaired in H3K27M Pediatric Glioma

In addition, PRC2 has been shown to automethylate its core subunits, EZH1/ EZH2 and SUZ12. Here, we identify the lysine residues at which EZH1/EZH2 are automethylated with EZH2-K510 and EZH2-K514 being the major such sites in vivo. Automethylated EZH2/PRC2 exhibits a higher level of histone methyltransferase activity and is required for attaining proper cellular levels of H3K27me3. While occurring inde- pendently of PRC2 recruitment to chromatin, automethylation promotes PRC2 accessibility to the histone H3 tail. Intriguingly, EZH2 automethylation is significantly reduced in diffuse intrinsic pontine glioma (DIPG) cells that carry a lysine-to-methionine substitution in histone H3 (H3K27M), but not in cells that carry either EZH2 or EED mutants that abrogate PRC2 allosteric activation, indicating that H3K27M impairs the intrinsic activity of PRC2. -

Epigenetic modifications are important contributors 1. Introduction to the regulation of genes within the chromatin. The poly- comb repressive complex 2 (PRC2) is a multi‑subunit protein Epigenetic modifications, including DNA methylation complex that is involved in silencing gene expression through and histone modifications, play an important role in gene the trimethylation of lysine 27 at histone 3 (H3K27me3). The regulation. The dysregulation of these modifications can dysregulation of this modification has been associated with result in pathogenicity, including tumorigenicity. Research tumorigenicity through the increased repression of tumour has indicated an important influence of the trimethylation suppressor genes via condensing DNA to reduce access to the modification at lysine 27 on histone H3 (H3K27me3) within transcription start site (TSS) within tumor suppressor gene chromatin. This methylation is involved in the repression promoters. In the present review, the core proteins of PRC2, as of multiple genes within the genome by condensing DNA well as key accessory proteins, will be described. In addition, to reduce access to the transcription start site (TSS) within mechanisms controlling the recruitment of the PRC2 complex gene promoter sequences (1). The recruitment of H1.2, an H1 to H3K27 will be outlined. Finally, literature identifying the histone subtype, by the H3K27me3 modification has been a role of PRC2 in breast cancer proliferation, apoptosis and suggested as a mechanism for mediating this compaction (1). -

LCoR and RIP140 form a nuclear complex in breast cancer cells and are of prognostic value in further prostate and cervical cancer. The purpose of this study was to analyze the regulation of these proteins in the development of cervical intraepithelial neoplasia (CIN I–III). Methods Immunohistochemical analysis was obtained to quantify RIP140 and LCoR expression in formalin-fxed parafn embedded tissue sections of cervical intraepithelial neoplasia samples. Tissue (n = 94) was collected from patients treated in the Department of Gynecology and Obstetrics, Ludwig-Maximilians-University of Munich, Germany, between 2002 and 2014. Correlations of expression levels with clinical outcome were carried out to assess for prognostic relevance in patients with CIN2 progression. Kruskal–Wallis test and Mann–Whitney U test were used for data analysis. Results Nuclear LCoR overexpression correlates signifcantly with CIN II progression. Nuclear RIP140 expression signif- cantly increases and nuclear LCoR expression decreases with higher grading of cervical intraepithelial neoplasia. -

Engaging Chromatin: PRC2 Structure Meets Function
www.nature.com/bjc REVIEW ARTICLE Engaging chromatin: PRC2 structure meets function Paul Chammas1, Ivano Mocavini1 and Luciano Di Croce1,2,3 Polycomb repressive complex 2 (PRC2) is a key epigenetic multiprotein complex involved in the regulation of gene expression in metazoans. PRC2 is formed by a tetrameric core that endows the complex with histone methyltransferase activity, allowing it to mono-, di- and tri-methylate histone H3 on lysine 27 (H3K27me1/2/3); H3K27me3 is a hallmark of facultative heterochromatin. The core complex of PRC2 is bound by several associated factors that are responsible for modulating its targeting specificity and enzymatic activity. Depletion and/or mutation of the subunits of this complex can result in severe developmental defects, or even lethality. Furthermore, mutations of these proteins in somatic cells can be drivers of tumorigenesis, by altering the transcriptional regulation of key tumour suppressors or oncogenes. In this review, we present the latest results from structural studies that have characterised PRC2 composition and function. We compare this information with data and literature for both gain-of function and loss-of-function missense mutations in cancers to provide an overview of the impact of these mutations on PRC2 activity.

Abstract Previous studies demonstrated that genome-wide PRC2 occupancy is largely reduced in primitive mESCs cultured in 2 inhibitors-containing medium. To understand the underlying mechanisms, we performed RNA-sequencing analyses to show the expression of Jarid2 and Eed is significantly reduced in primitive mESCs due to blocking of the FGF/MAPK pathway. ChIP-seq analyses showed that decreased genome-wide occupancy of Ezh2 and H3K27me3 modification is correlated with a global reduction of Jarid2 occupancy. The ectopic expression of Jarid2 partially restores both global PRC2 occupancy and H3K27me3 modification. -
Regulation of Peripheral Nerve Myelin Maintenance by Gene Repression Through Polycomb Repressive Complex 2

Orkin,4 and John Svaren1,3 1Waisman Center, 2Cellular and Molecular Pathology Graduate Program, 3Department of Comparative Biosciences, University of Wisconsin-Madison, Madison, Wisconsin 53705, and 4Dana Farber Cancer Institute and Boston Children’s Hospital, Harvard Medical School and Howard Hughes Medical Institute, Boston, Massachusetts 02115 Myelination of peripheral nerves by Schwann cells requires coordinate regulation of gene repression as well as gene activation. Several chromatin remodeling pathways critical for peripheral nerve myelination have been identified, but the functions of histone methylation in the peripheral nerve have not been elucidated. To determine the role of histone H3 Lys27 methylation, we have generated mice with a Schwann cell-specific knock-out of Eed, which is an essential subunit of the polycomb repressive complex 2 (PRC2) that catalyzes methylation of histone H3 Lys27. Analysis of this mutant revealed no significant effects on early postnatal development of myelin. However, its loss eventually causes progressive hypermyelination of small-diameter axons and apparent fragmentation of Remak bun- dles. These data identify the PRC2 complex as an epigenomic modulator of mature myelin thickness, which is associated with changes in Akt phosphorylation. Interestingly, we found that Eed inactivation causes derepression of several genes, e.g., Sonic hedgehog (Shh) and Insulin-like growth factor-binding protein 2 (Igfbp2), that become activated after nerve injury, but without activation of a primary regulator of the injury program, c-Jun. -
