A, Dose-dependent effect of membrane-impermeable protein-conjugated E2 (E2-BSA) on contractility of female myocytes (n = 25–26). A maximal equivalent concentration of BSA served as control (n = 26), and 10−9 m unconjugated E2 plus maximal equivalent concentration of BSA served as positive control (n = 27). B, Effects of BPA or E2 (10−9 m) on contractility of female myocytes in the absence and presence of 50 μm l-NAME (n = 19–25). There is no statistically significant difference (P > 0.1) between groups without l-NAME and their respective l-NAME-treated groups. Error bars are sem. *, P < 0.05; **, P < 0.01 vs. control in a one-way ANOVA. NS (not significant), P > 0.1.
