Location analysis of estrogen receptor α target promoters reveals that FOXA1 defines a domain of the estrogen response

Nuclear receptors can activate diverse biological pathways within a target cell in response to their cognate ligands, but how this compartmentalization is achieved at the level of gene regulation is poorly understood. We used a genome-wide analysis of promoter occupancy by the estrogen receptor alpha (ERalpha) in MCF-7 cells to investigate the molecular mechanisms underlying the action of 17beta-estradiol (E2) in controlling the growth of breast...
