In order to obtain information regarding the extent to which FOXA1 cooperates with GATA3 and PPARɣ, as well as to identify other transcription factors that potentially regulate gene expression in a luminal bladder cancer cells, we performed chromatin immunoprecipitation of FOXA1 in RT4 cells followed by high throughput next generation sequencing (ChIP-Seq). The gene discussed is GATA3; the disease is urinary bladder carcinoma.
