(Submitter supplied) A cardinal property of neural stem cells (NSCs) is their ability to adopt multiple fates upon differentiation. The epigenome is widely seen as a read-out of cellular potential and a manifestation of this can be seen in embryonic stem cells (ESCs), where promoters of many lineage-specific regulators are marked by a bivalent epigenetic signature comprising trimethylation of both lysine 4 and lysine 27 of histone H3 (H3K4me3 and H3K27me3, respectively). more...

(Submitter supplied) All data are derived from the same batch of human ES cells (line H9, WA-09). With the exception of the “UD” file all files represent neural cell types derived from the undifferentiated hESCs. Following mechanical isolation, rosettes were maintained for various passages in the presence of defined growth factors and morphogen factors as indicated below at the R-NSC stage. Cells at the NSCFGF/EGF stage were derived from mechanically isolated neural rosettes that were purified and long-term expanded as attached monolayer cultures in serum free medium in the presence of FGF2/EGF. more...

(Submitter supplied) Trimethylation of histone 3 lysine 4 (H3K4me3) at promoters of actively transcribed genes is a universal epigenetic mark and a key product of Trithorax-Group action. Here we show that Mll2, one of the six Set1/Trithorax-type H3K4 methyltransferases in mammals, is required for trimethylation of bivalent promoters in mouse embryonic stem cells. Mll2 is bound to bivalent promoters but also to most active promoters, which do not require Mll2 for H3K4me3 or mRNA expression. more...

(Submitter supplied) Genome-wide mapping of transcriptional regulatory elements are essential tools for the understanding of the molecular events orchestrating self-renewal, commitment and differentiation of stem cells. We combined high-throughput identification of nascent, Pol-II-transcribed RNAs by Cap Analysis of Gene Expression (CAGE-Seq) with genome-wide profiling of histones modifications by chromatin immunoprecipitation (ChIP-seq) to map active promoters and enhancers in a model of human neural commitment, represented by embryonic stem cells (ESCs) induced to differentiate into self-renewing neuroepithelial-like stem cells (NESC). more...

(Submitter supplied) Aberrational epigenetic marks are believed to play a major role in establishing the abnormal features of cancer cells. Rational use and development of drugs aimed at epigenetic processes requires an understanding of the range, extent, and roles of epigenetic reprogramming in cancer cells. Using ChIP-chip and MeDIP-chip approaches, we localized well-established and prevalent epigenetic marks (H3K27me3, H3K4me3, H3K9me3, DNA methylation) on a genome scale in several lines of putative glioma stem cells (brain tumor stem cells, BTSCs) and, for comparison, normal human fetal neural stem cells (fNSCs). more...

(Submitter supplied) The molecular signature at histone H3K4me3 and H3K27me3 involved in epigenetic regulation of normal (MCF10A) and transformed (MCF7, MDA-MB-231) breast cells using ChIP-Seq technology. This study examines the dynamic distribution of H3K4me3, associated with active chromatin, and H3K27me3, associated with repressed chromatin, histone modifications to provide an understanding of the changes in epigenetic regulation associated with the unique breast cancer subtypes.

(Submitter supplied) Multipotent mesenchymal stromal cells (MSCs) from bone marrow are critical for regeneration and homeostasis of multiple tissues. As epigenetic mechanisms are a fundamental regulator of lineage specification and cell fate, we examined histone modification changes in MSCs at distinct stages osteogenic differentiation, including: proliferation, early commitment, matrix deposition, and mineralization. Temporal changes of multiple histone modifications along with several transcriptional regulators were assessed and correlated to gene expression, which revealed distinct epigenetic mechanisms that regulate transcriptional programs necessary for commitment and tissue-specific phenotype development. more...
