ProteomicsPCGF1-PRC1 links chromatin repression with DNA replication during hematopoietic cell lineage commitment
Polycomb repressive complexes 1 and 2 (PRC1 and 2) repress lineage inappropriate genes during development to maintain proper cellular identities. To reveal the function of a variant PRC1 containing PCGF1 (PCGF1-PRC1), we prepared PCGF1 interacting proteins by immunoprecipitation and characterized th...

GenomicsRING1B binding in the 11 dpc embryonic tissues
We report the distribution of RING1B (one of Polycomb group factors) within the genome of mouse embryonic tissues. We prepared the chromatin from 11 dpc embryonic forebrain, midbrain, and forelimb buds and made chromatin precipitation with antibody against RING1B (mouse monoclonal antibody). High-th...

GenomicsEnhancer landscape of mouse developing midbrain at 11.5 dpc embryos
We report the distribution of histone H3K4me1 and H3K27ac within the genome of mouse embryonic midbrain. We prepared the chromatin from 11 dpc embryonic midbrain and made chromatin precipitation with antibody against H3K4me1 and H3K27ac (rabbit polyclonal antibody). High-throughput sequencing appli...

Transcriptomics4C-seq indicate interactive sites with the sequence close from Meis2 promoter
We report the distribution of interactive sites with the sequence close from Meis2 promoter within the genome of mouse embryonic forebrain. We prepared the chromatin from 11 dpc embryonic forebrain and made 3C (chromosomal conformation capture) library. High-throughput sequencing applied for the 3C ...

TranscriptomicsLoss of Ezh2 promotes a midbrain-to-forebrain identity switch by direct gene derepression and Wnt-dependent regulation
Background: Precise spatiotemporal control of gene expression is essential for the establishment of correct cell numbers and identities during brain development. This process involves epigenetic control mechanisms, such as those mediated by the polycomb group protein Ezh2 that catalyzes trimethylat...

ProteomicsSKP1A-mediated degradation of PRC2 triggers activation of Polycomb-silenced genes
Polycomb group (PcG) proteins are evolutionarily conserved repressors of developmental genes. Paradoxically, the same PcG proteins also play roles in gene activation via mechanisms that are not yet fully understood. Here, to reveal the function of S-phase kinase-associated protein 1A (SKP1A), an ess...

TranscriptomicsExpression data from Ring1A(-/-);Ring1B(fl/fl);R26::CreERT2 ES cells expressing either of mock, WT or mutant Ring1B construct before or after OHT treatment
We used microarrays to investigate the restoration of repression of PRC1 target gene expression in Ring1A/B-dKO ES cells stably expressing either of mock, WT or mutant Ring1B construct. Total RNAs were extracted from the respective ES cells, and were subjected to microarray analysis using Affymetrix...

GenomicsFunctional analysis of AEBP2, a PRC2 Polycomb protein, reveals a Trithorax phenotype in embryonic development and in ES cells
The Polycomb repressive complexes PRC1 and PRC2 are key mediators of heritable gene silencing in multicellular organisms. Here we characterize AEBP2, a known PRC2 cofactor which, in vitro, has been shown to stimulate PRC2 activity. We show that AEBP2 localises specifically to PRC2 target loci, incl...
