Dose-response curves of specific agonists on SF-1 (a) and P₄₅₀Arom (b) protein content. Endometrial epithelial cells obtained from 4 control women were treated with E₂ (10⁻⁸ mol/L), PPT (10⁻⁹ to 10⁻⁷ mol/L), DPN (10⁻⁹ to 10⁻⁷ mol/L), and G1 (10⁻⁸ to 10⁻⁶ mol/L). Representative immunoblots are shown. Data for SF-1 (nuclear homogenates) were normalized with TFIIB and for P450Arom (cytosol homogenates) with GAPDH. Results are the mean ± SEM. *p < 0.05 vs. basal
