GenomicsJarid2 and PRC2, Partner in Regulating Gene Expression
The Polycomb Group proteins foster gene repression profiles required for proper development and unimpaired adulthood, and comprise the components of the PRC2 complex including the histone H3 lysine 27 (H3K27) methyltransferase Ezh2. How mammalian PRC2 accesses chromatin is unclear. We find that Jari...

GenomicsGenome-wide maps of chromatin state in pluripotent and lineage-committed cells
Genome-wide maps of chromatin state (H3K4me3, H3K9me3, H3K27me3, H3K36me3, H4K20me3) in pluripotent and lineage-committed cells We report the application of single-molecule-based sequencing technology for high-throughput profiling of histone modifications in mammalian cells. By obtaining over four b...

GenomicsMapping polycomb complexes in human and mouse embryonic stem cells
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 m...

GenomicsSAM domain polymerization links subnuclear clustering of PRC1 to silencing
Polycomb group (PcG) proteins mediate heritable but reversible silencing of developmental regulator genes by modifying their chromatin configuration. Accumulating evidence documents a role for PcG proteins in regulating higher order chromatin structures likely by their clustering, however, underlyin...

GenomicsH2A.Z landscapes and dual modifications in pluripotent and multipotent stem cells underlie complex genome regulatory functions
The histone variant H2A.Z has been implicated in nucleosome exchange, transcriptional activation and Polycomb repression. However, the relationships among these seemingly disparate functions remain obscure. We mapped H2A.Z genome-wide in mammalian ES cells and neural progenitors. H2A.Z is deposited ...

TranscriptomicsMapping and analysis of chromatin state dynamics in nine human cell types (gene expression)
Chromatin profiling has emerged as a powerful means for annotating genomic elements and detecting regulatory activity. Here we generate and analyze a compendium of epigenomic maps for nine chromatin marks across nine cell types, in order to systematically characterize cis-regulatory elements, their ...

TranscriptomicsTranscription profiling of mouse ES cells, neural precursor cells and embryonic fibroblasts
Expression profiles for isogenic (129SvJae x C57BL/6) murine embryonic stem (ES) cells, neural precursors (NPC) obtained through in vitro differentiation of the ES cells, and embryonic fibroblasts (MEF) obtained at day 13.5. Experiment Overall Design: 3 replicates of wt ES cells, 3 replicates of wt...
