ProteomicsDynamic protein interactions of the Polycomb Repressive Complex 2
Polycomb proteins assemble to form complexes with important roles in epigenetic regulation. The Polycomb Repressive Complex 2 (PRC2) modulates the di- and tri-methylation of lysine 27 on histone H3, each of which are associated with gene repression. Although three subunits, EZH1/2, SUZ12 and EED, fo...

GenomicsDirect Recruitment of Polycomb Repressive Complex 1 (PRC1) to Chromatin by Core Binding Transcription Factors (ChIP-Seq)
Polycomb repressive complexes (PRCs) play key roles in developmental epigenetic regulation. Yet the mechanisms that target PRCs to specific loci in mammalian cells remain incompletely understood. In this study, we show that Bmi1, a core component of Polycomb Repressive Complex 1 (PRC1), binds direct...

TranscriptomicsGenome-wide Identification of Polycomb Target Genes Reveals a Functional Association of Pho with Scm in Bombyx mori
Polycomb group (PcG) proteins are involved in chromatin modifications for maintaining gene repression that play important roles in the regulation of gene expression, tumorigenesis, chromosome X-inactivation, and genomic imprinting in Drosophila melanogaster, mammals, and even plants. PcG proteins ac...

TranscriptomicsThe Polycomb protein Pcgf2/Mel18 regulates mesoderm cell fate-specification of embryonic stem cells through multiple mechanisms
Polycomb complexes are essential regulators of stem cell identity, yet very little is known about their molecular mechanisms during cell differentiation. Pcgf proteins (Pcgf1/2/3/4/5/6) are core subunits of the Polycomb repressive complex 1 (PRC1). It has been recently proposed that specific Pcgf pr...

TranscriptomicsdKDM2 couples histone H2A ubiquitylation to histone H3 demethylation during Polycomb group silencing.
Transcription regulation involves enzyme-mediated changes in chromatin structure. Here, we describe a novel mode of histone crosstalk during gene silencing, in which histone H2A monoubiquitylation is coupled to the removal of histone H3 Lys 36 dimethylation (H3K36me2). This pathway was uncovered thr...

TranscriptomicsGene silencing triggers Polycomb Repressive Complex 2 recruitment to CpG islands genome-wide [RNA-seq_differentiation]
Polycomb group (PcG) proteins are required for normal differentiation and development, and their activity is found deregulated in cancer. PcG proteins are involved in gene silencing, however, whether they initiate or maintain transcriptional repression is a subject of debate. Here, we show that knoc...

TranscriptomicsFrequent switching of Polycomb repressive marks and DNA hypermethylation in the PC3 prostate cancer cell line
Epigenetic reprogramming is commonly observed in cancer, and is hypothesized to involve multiple mechanisms, including DNA methylation and Polycomb repressive complexes (PRCs). Here we devise a new experimental and analytical strategy using customized high density tiling arrays to investigate coordi...
