(Submitter supplied) Formation of the blood from self-renewing hematopoietic stem cells to terminal lineages necessarily involves epigenomic modifications of the genome to control regulator and signature gene expression. By analysing the global expression profiles of hematopoietic stem cells (HSCs), in vivo differentiated CD4+ T cells and CD19+ B cells as well as in vitro differentiated erythrocyte precursor cells, we identified hundreds of transcripts showing type-specific expression in these cell types. more...

(Submitter supplied) Histone modifications have been implicated in stem cell maintenance and differentiation. We have analyzed genome-wide changes in gene expression and histone modifications during differentiation of multipotent human primary hematopoietic stem cells/progenitor cells (HSCs/HPCs) into erythrocyte precursors. Our data indicate that H3K4me1, H3K9me1, and H3K27me1 associate with enhancers of differentiation genes prior to their activation and correlate with basal expression, suggesting that these monomethylations are involved in the maintenance of activation potential required for differentiation. more...

(Submitter supplied) Purpose: Study hypoxia and reoxygenation induced changes in genome-wide H3K4me3 and H3K27me3 occupancy Methods: Using the MCF7 breast epithelial adenocarcinoma cell line as a model, we studied epigenomic reprogramming as a function of fluctuating oxygen tension. To this end, we combined chromatin-immunoprecipitation and deep-sequencing analysis to identify H3K4me3-marks and H3K27me3-marks in MCF7 cells subjected to changes in oxygenation (i.e. more...

(Submitter supplied) Post-translational histone modifications modulate chromatin packing to regulate gene expression. How chromatin states, both at euchromatic and at heterochromatic regions, underlie cell fate decisions in single cells is relatively unexplored. We develop sort assisted single-cell chromatin immunocleavage (sortChIC) and apply it to map active (H3K4me1 and H3K4me3) and repressive (H3K27me3 and H3K9me3) histone modifications in hematopoietic stem and progenitor cells (HSPCs), and mature blood cells in the mouse bone marrow. more...

(Submitter supplied) Conditional deletion of Geminin from the entire hematopoietic compartment using Vav1:iCre mice led to defective hematopoiesis/dyserythropoiesis in E15.5 mouse embryos. The present data set includes data from lineage-negative cells isolated from homogenized livers that were dissected from E15.5.dpc embryos. The two conditions compared were wild-type versus Geminin-KO Lin- cells. The cells were collected from littermates.

(Submitter supplied) The H2A variant H2AZ is essential for embryonic development and for proper execution of developmental gene expression programs in embryonic stem cells (ESCs). Divergent regions in H2AZ are likely key for its functional specialization, but we know little about how these differences contribute to chromatin regulation. Here, we show that the extended acidic patch, specifically the three divergent residues in the C-terminal docking domain, is necessary for lineage commitment during ESC differentiation and proper execution of gene expression programs during ESC differentiation. more...

(Submitter supplied) Genome-wide maps of cytosine methylation, cytosine hydroxylmethylation and small non coding RNAs in mouse ES cells and upon guided differentiation to mesoendoderm cells. Mouse embryonic stem cells (E14) were guided differentiated into mesoendoderm lineages by activin-A induction. cells in three time points (day0, day4 and day6) were collected. The genome-wide studies on three cell types were summerized as following: cytosine methylation data were generated using methylated DNA immunoprecipitation followed by sequencing (MeDIP-seq) and DNA digestion by methyl-sensitive restriction enzymes followed by sequencing (MRE-seq); DNA product for 5-hmC_ChIP-seq is generated by a selctive chemical labeling method (Nat. more...

(Submitter supplied) Histone modifications play critical roles in regulating developmental genes expression during embryo development in mammals1,2. However, genome-wide analysis of histone modifications in pre-implantation embryos has been impeded by technical difficulties and the scarcity of required materials. Here, by using a small-scale chromatin immunoprecipitation sequencing (ChIP-seq) method3, for the first time, we mapped the genome-wide profile of histone H3 lysine 4 trimethylation (H3K4me3) and histone H3 lysine 27 trimethylation (H3K27me3), associated with gene activation and repression respectively, in mouse pre-implantation embryos. more...

(Submitter supplied) Around implantation, the epiblast transits from naïve to primed pluripotency, before giving rise to the three germ layers. How chromatin is reconfigured during this developmental window remains poorly understood. We performed a genome-wide investigation of chromatin landscapes during this period. We find that enhancers in ectoderm are already pre-accessible in embryonic day 6.5 (E6.5) Epi when cells enter a primed pluripotent state. more...

(Submitter supplied) By mapping the genomic enrichments  of H3K4me3 and H3K27me3 modifications in pure populations of hESCs during the G2, mitotic and G1 phases of the cell cycle, we characterize cell cycle-dependent variations in the epigenetic landscape of bivalent genes, altering the current view of mitotic inheritance in pluripotent cells. We identified novel classes of bivalent domains that are highly enriched with H3K4me3 during mitosis, depleted during G1 only, and ubiquitously bivalent. more...
