Transcriptional activity of R269C-ER in breast and pancreatic cancer cells. Cells were transiently transfected with either WT-ER or R269C-ER vectors together with the ERE luciferase reporter and treated with E2 (10nM) or a control vehicle for 24 h. Luciferase activity were analyzed and normalized to Renilla luciferase units and are shown relative to the control WT-ER. The results are from a representative experiment of at least three independent experiments, each performed in hexaplicates. Each bar represents the mean ± SD. *, P < 0.05, **, P < 0.01
