a The localization and expression of ERα, ERβ, AR and PR proteins in uncomplicated pregnancies (upper panel) and preeclampsia placenta (bottom panel) were analyzed by immunohistochemical analysis. Specific and robust ERβ immunostaining was detected exclusively in the nucleus and cytoplasm of syncytiotrophoblasts (arrowhead) and stromal cells (arrow). Magnification × 400. b Comparison of ERα, ERβ, AR and PR protein expression in placenta from preeclampsia between the two groups by western blot. ERα and ERβ protein expression was significantly lower and higher, respectively, in preeclampsia
