ABSTRACT

It is reported that expression of vascular endothelial growth factor (VEGF) in trophoblasts increases in cases with preeclampsia. Recently, we demonstrated that the lack of cyclin-dependent kinase inhibitor, p57kip2, expression in the fetus and the placenta plays a role in the development of preeclampsia-like symptoms in pregnant mice. Furthermore, we observed that VEGF mRNA and protein levels, especially VEGF164, were higher and its expression was stronger in placentas of p57kip2-null embryos than in placentas of wild-type embryos. In this study we investigated whether exogenous murine VEGF164 induced preeclampsia-like symptoms in pregnant mice, and anti-VEGF neutralized antibody could suppress these symptoms. Administration of VEGF induced hypercoagulation in the placental circulation and a significant elevation of systolic blood pressure in pregnant mice. Furthermore, we demonstrated that treatment with anti-VEGF antibody could suppress the hypercoagulability in placenta and the elevation of systolic blood pressure. These data suggest that VEGF is related to the pathophysiology of preeclampsia.
