Project description:Maps of open chromatin in three primary human blood cell types of the myeloid lineage (megakaryocytes, erythroblasts and monocytes) using the formaldehyde-assisted isolation of regulatory elements method followed by next-generation sequencing (FAIRE-seq). We also generated FAIRE-seq data in the megakaryocytic cell line CHRF-288-11. In addition to our data sets, we retrieved FAIRE-seq data for the erythroblastoid cell line K562 (ENCODE Project Consortium 2012) and pancreatic islets (Gaulton et al. 2010), and reanalyzed these data sets using the same methodology.

Project description:We report the open chromatin landscape in primary human macrophages and foam cells using FAIRE-seq CD14+ monocytes were isolated from the blood of 3 healthy volunteers. Monocytes were differentiated into macrophages by culture for 7 days with 50ng/ml macrophage colony stimulating factor and then treated for 48 hours with either oxidized low density lipoprotein (oxLDL) to induce foam cell formation or with a control buffer that lacked oxLDL. The resulting six samples were then subjected to FAIRE-seq using an established protocol (Simon JM, Giresi PG, Davis IJ, Lieb JD. Using formaldehyde-assisted isolation of regulatory elements (FAIRE) to isolate active regulatory DNA. Nature protocols 2012;7:256-67).

Project description:Genomic enhancers regulate spatio-temporal gene expression by recruiting specific combinations of transcription factors (TFs). When TFs are bound to active regulatory regions, they displace canonical nucleosomes, making these regions biochemically detectable as nucleosome-depleted regions or accessible/open chromatin. Here we ask whether open chromatin profiling can be used to identify the entire repertoire of active promoters and enhancers underlying tissue-specific gene expression during normal development and oncogenesis in vivo. To this end, we first compare two different approaches to detect open chromatin in vivo using the Drosophila eye primordium as a model system: FAIRE-seq, based on physical separation of open versus closed chromatin; and ATAC-seq, based on preferential integration of a transposon into open chromatin. We find that both methods reproducibly capture the tissue-specific chromatin activity of regulatory regions, including promoters, enhancers, and insulators. Using both techniques, we screened for regulatory regions that become ectopically active during Ras-dependent oncogenesis, and identified 3778 regions that become (over-)activated during tumor development. Next, we applied motif discovery to search for candidate transcription factors that could bind these regions and identified AP-1 and Stat92E as key regulators. We validated the importance of Stat92E in the development of the tumors by introducing a loss of function Stat92E mutant, which was sufficient to rescue the tumor phenotype. Additionally we tested if the predicted Stat92E responsive regulatory regions are genuine, using ectopic induction of JAK/STAT signaling in developing eye discs, and observed that similar chromatin changes indeed occurred. Finally, we determine that these are functionally significant regulatory changes, as nearby target genes are up- or down-regulated. In conclusion, we show that FAIRE-seq and ATAC-seq based open chromatin profiling, combined with motif discovery, is a straightforward approach to identify functional genomic regulatory regions, master regulators, and gene regulatory networks controlling complex in vivo processes.
