Abstract
- Objective: Preeclampsia (preE), a syndrome of hypertension, and end organ damage, is a leading cause of maternal and fetal morbidity and mortality. Recently, we and other researchers have shown that circulating (pro)renin, soluble (pro)renin receptor (s(P)RR) and placental (P)RR were significantly higher during preE compared to normal pregnancy (NP). In this study, placental expression of (P)RR and serum s(P)RR were evaluated in preE human patients and various rat models of preE. Study Design: (1) Placenta and blood samples were collected from 40 NP and 30 consented preE patients; (2) expression of (P)RR in placenta and soluble (P)RR were evaluated in two established preE rat models: reduced uterine perfusion pressure (RUPP) and deoxycorticosterone acetate (DOCA; PDS) models of preE and were compared to normal pregnant (NP) (SD) rats (n=8). We measured the expression of (P)RR by western blotting (WB) and immunohistochemistry. Plasma (pro)renin and s(P)RR were detected using a commercially available ELISA Kit. Results: The placental expression of (P)RR was higher (p* Conclusions: These data suggest that increased expression of (P)RR in the placenta and s(P)RR are associated with placental ischemia related to the occurrence of preE in both human patients and animal models of disease.
