Transcriptional activation of (a) 2×ERE and (b) GREB-ERE2 luciferase reporters by ERα and LRH-1 with vehicle (veh) or 10 nM 17β-estradiol (E2). Estrogen-deprived MCF-7 cells were over expressed with LRH-1 or ERα alone, or in combination with the appropriate reporter construct. Cells were treated with 17β-estradiol for 16 h prior to luciferase assays. Data is presented as mean+SE, n = 3 separate experiments, treatments in triplicate per experiment. *P<0.05, *P<0.01, ***P<0.001 compared to vehicle control unless indicated by reference line.
