Estrogen receptor α (ER α) and ERβ expression in MCF-7 cells.
Western blot analysis of ER subtype expression in MCF-7 cells was carried out as described in the Materials and Methods. *p < 0.05, compared to DMSO; #p < 0.05, ##p < 0.01, compared to 0.01 μM E2; (△) p < 0.05, compared to QBMRE. (▲) p < 0.05, compared with ERα protein relative increase to Control.
