(Submitter supplied) Mammalian erythropoiesis yields a highly specialized cell type, the mature erythrocyte, evolved to meet organismal needs of increased oxygen carrying capacity. To better understand regulation of erythropoiesis, we performed genome-wide chromatin accessibility studies, DNA methylation studies, and transcriptome analyses and correlated this with genomic organization in highly purified populations of primary human erythroid cells across the stages of erythroid development and differentiation. more...

(Submitter supplied) CTCF and cohesinSA-1 are regulatory proteins involved in a number of critical cellular processes including transcription, maintenance of chromatin domain architecture, and insulator function. To assess changes in the CTCF and cohesinSA-1 interactomes during erythropoiesis, chromatin immunoprecipitation coupled with high throughput sequencing and mRNA transcriptome analyses via RNA-seq were performed in primary human HSPC hematopoietic stem and progenitor cells (HSPC) and primary human erythroid cells from single donors. more...

(Submitter supplied) The modulation of chromatin structure is a key step in transcription regulation in eukaryotic cells. Mammalian erythropoiesis is accompanied by dynamic alterations in chromatin structure and gene expression, but the epigenetic regulators that modulate and coordinate these changes are largely unknown. USF, Setd1a and NURF complexes interact to regulate chromatin architecture in erythropoiesis, but the basis for this regulation is unknown. more...

(Submitter supplied) Identification of cell-type specific enhancers is important for understanding the regulation of programs controlling cellular development and differentiation. Enhancers are typically marked by the co-transcriptional activator protein p300 or by groups of cell-expressed transcription factors. We hypothesized that a unique set of enhancers regulates gene expression in human erythroid cells, a highly specialized cell type evolved to provide adequate amounts of oxygen throughout the body. more...

(Submitter supplied) Enhancers of transcription activate transcription via binding of sequence-specific transcription factors to their target sites in chromatin. In this report, we identify GATA1-bound enhancers genome-wide and find a global reorganization of the nucleosomes at these enhancers during differentiation of hematopoietic stem cells (HSCs) to erythrocytes. We show that the catalytic subunit BRG1 of BAF complexes localizes to these enhancers during differentiation and generates a longer nucleosome repeat length surrounding the GATA1 sites by shifting the flanking nucleosomes away. more...

(Submitter supplied) We report ChIP-Seq data for GATA1 and the leukemia-associated short isoform GATA1s in G1ME cells, a Gata1-null cell line with both erythroid and megakaryocytic differentiation potential. We introduced HA-tagged GATA1 or GATA1s into G1ME cells via retroviral transduction. The cells were crosslinked at 48h post-transduction, and an HA antibody was used for chromatin immunoprecipitation (ChIP). ChIP and input samples were sequenced on Illumina GAII or GAIIx high-throughput sequencers. more...

(Submitter supplied) In mammals, extensive chromatin reorganization is essential for reprogramming terminally committed gametes to a totipotent state during preimplantation development. However, the global chromatin landscape and its dynamics in this period remain unexplored.
