Transcriptional activation by BRCA1 with a series of ExoIII-generated ER promoter luciferase constructs. Luciferase activity for ExoIII-generated ER promoter constructs in MCF10A cells. Fold induction in luciferase activity (x axis) is shown for ER promoter constructs following co-transfection with either a BRCA1 expression plasmid (filled bars) or the empty pRK7 vector (open bars). Fold induction values were calculated as in Fig. 2. Data shown represents the average of 2–7 experiments, with luciferase and protein measurements performed in triplicate for each experiment
