GenomicsCpG islands recruit a histone H3 lysine 36 demethylase [Illumina sequencing data]
Eukaryotic gene expression profiles are largely defined by transcription factors that recognize specific DNA sequences in gene regulatory regions and impact RNA polymerase recruitment and transcription. In addition to specific core promoter regulatory elements, up to 70% of genes in higher eukaryote...

TranscriptomicsCpG islands recruit a histone H3 lysine 36 demethylase [Agilent data]
Transcription factors that bind small DNA motifs embedded in promoters play a central role in controlling gene expression. However, in addition to these elements, up to 70% of genes in higher eukaryotes also have high levels of non-methylated cytosine/guanine base pairs (CpGs) surrounding promoters ...

GenomicsKDM2B binds CpG islands and modulates recruitment of Ring1b
CpG island elements are associated with most mammalian gene promoters, yet how they contribute to gene regulation remains poorly understood. Recently it has become clear that a subset of CpG islands in embryonic stem cells can act as polycomb response elements and are recognized by the polycomb sile...

TranscriptomicsThe presence of RNA polymerase II, active or stalled, predicts epigenetic fate of promoter CpG islands.
Instructive mechanisms are present for induction of DNA methylation, as shown by methylation of specific CpG islands (CGIs) by specific inducers and in specific cancers. However, instructive factors involved are poorly understood, except for involvement of low transcription and trimethylation of his...

TranscriptomicsClustering of CpG islands constitutes an important determinant of the interphase chromosome 3D organization [4C-Seq]
Using 4C-Seq experimental procedure we have characterized, in cultured chicken lymphoid and erythroid cells, genome-wide patterns of spatial contacts of several CpG islands scattered along the chromosome 14. A clear tendency for interaction of CpG islands present within the same and different chromo...

GenomicsComprehensive analysis of orphan CpG islands identifes novel promoters with conserved DNA methylation dynamics
We report the application of single molecule-based sequencing technology in combination with CXXC affinity purifcation (CAP-seq), MBD affinity purification (MAP-seq) and chromatin immunoprecipitation (ChIP-seq) to generate reciprocal methylation and chromatin modifcation maps in human and mouse. We ...

GenomicsA Primary Role of TET Proteins in Establishment and Maintenance of De Novo Bivalency at CpG Islands of Developmental Genes
TET protein-catalyzed 5mC oxidation not only creates novel DNA modifications such as 5hmC, but also initiates active or passive DNA demethylation. However, the TETs’ function in crosstalk with specific histone modifications is largely elusive. Here, we show that TET2-mediated DNA demethylation pla...

GenomicsGene silencing triggers Polycomb Repressive Complex 2 recruitment to CpG islands genome-wide [ChIP-seq_Input]
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...
