ER expression in MCF-7, HCC1428, MDA-MB-231 and BT549 cells. (A) ER protein levels were analyzed using western blotting. β-Actin levels were measured as a loading control. (B) Histograms illustrate ER protein expression relative to that of β-actin. All data corresponded to the mean ± SD of three independent experiments. (C) Immunofluorescence staining of ER in MCF-7, HCC1428, MDA-MB-231 and BT549 cells. Green represents ER staining. Blue signals represent nuclear DNA staining with DAPI. Scale bars indicate 25 μm.
