Project description:This SuperSeries is composed of the following subset Series: GSE35379: Genome-wide occupancy map of GATA-1 in proliferating and differentiating murine ES cell derived erythroid progenitors (ES-EP) GSE35384: Transcriptome analysis of differentiating normal and leukemic erythroid progenitors Refer to individual Series
Project description:We find GATA-1 occupies 6,600 sites in proliferating erythroid progenitors and 10,600 sites in differentiating progenitors. 80-90% of GATA-1 binds within intragenic or intergenic regions, while <20% of GATA-1 is found within 2kb of TSS. Assaying GATA-1 occupancy in normal erythroid progenitors in both proliferating and differentiating conditions.
Project description:We find that the myeloid master regulatory transcription factor, PU.1, binds to >16,000 sites in both normal and leukemic erythroid cells. Of these bound sites, ~7,000 lie within 2kb of TSS of a gene, suggesting PU.1 may regulate a large number of genes in erythroid cells. Coupling this data with gene expression analysis, we show PU.1 directly regulates several critical signaling pathways in erythroid cells. Assaying PU.1 occupancy in normal and leukemic erythroid cells
