ERβ expression. A, mean expression intensities of ERβ at the mRNA level based on microarray normalized results under five different conditions: Tet+ and ICI (sample A; Table I), Tet− and ICI (sample B; Table I), Tet+ and genistein (sample C; Table I), Tet− and genistein (sample D; Table I), and Tet− in control cell line (T47D-PBI) and genistein (sample E; Table I). Each data point represents the mean of triplicate exposure ± standard deviation. B, picture of cells (upper) and green fluorescent protein (enhanced GFP) detection (lower) of Tet+ (left)- and Tet− (right)-cultured cells treated with genistein.
