Dose-response curves of specific agonists on USF2a (a) and USF2b (b) nuclear protein content. Endometrial epithelial cells obtained from 4 control women were treated for 24 h 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) in the presence or absence of ICI (10−6 mol/L; 40 min previously added). Representative immunoblot is shown. Data were normalized with TFIIB. Results are the mean ± SEM of EEC obtained from at least 4 control women. *p < 0.05 vs. basal; #p < 0.05 vs. agonist
