Hypertensive disorders of pregnancy (HDP) is the most common medical problem encountered during pregnancy. Dysfunction of the placenta is thought to be one of the causes of HDP, but detailed mechanism is still unknown. In this study, we investigated the mechanism of decreased AQP1 expression in the placenta of HDP model mice and explored WAKANYAKU that can pharmacologically modulate AQP1 expression. Analysis of placental tissue at various stages of pregnancy suggested that the decrease in AQP1 caused by inflammatory cytokines may increase the fragility of placental tissue, resulting in placental tissue dysfunction. In addition, several herbal extracts and their components inhibit the RAA system, which is overactivated in HDP. These results might to be an useful data for establishing new treatment methods for HDP.
