Figure 4From: Estrogen receptor beta inhibits transcriptional activity of hypoxia inducible factor-1 through the downregulation of arylhydrocarbon receptor nuclear translocatorEffects of ERβ on ARNT binding with HIF-1α. HEK293 cells in 100 mm2 dish were cotransfected with GFP-HIF-1α (10 μg) and hERβ (10 or 20 μg) or ARNT plasmid (10 μg) as indicated. Cell lysates were immunoprecipitated with anti-HIF-1α antibody and precipitated proteins were analyzed by immunoblots with anti-HIF-1α (top) or anti-ARNT antibody (bottom). Shown are representative results from two to three separate experiments.Back to article page
