Preeclampsia is a serious complication of pregnancy with no medical treatment. It is caused by intermittent placental hypoxia and release of sFlt-1 and soluble endoglin, leading to wide spread maternal endothelial dysfunction and multisystem organ injury. YC-1 is a guanylyl cyclase activator and HIF1α inhibitor developed for use in hypertension and atherosclerosis. We examined whether YC-1 reduces sFlt-1 and sENG secretion and reverses endothelial dysfunction in primary human tissues. YC-1 significantly reduced sFlt-1 and sENG secretion from human umbilical vein endothelial cells, purified primary trophoblast cells and placental explants taken from patients with preterm preeclampsia.
