Endothelin-converting enzyme-1(ECE-1) is a key regulatory enzyme in the processing of endothelin-1 (ET-1). We quantified and localized ECE-1 in normal and preeclamptic placentas. Normal (n=6) and preeclamptic (n=6) placentas were serially sectioned for immunofluorescence (IF). Cell type specific markers identified endothelial, trophoblast, macrophage, smooth muscle, and fibroblast cells. Quantitative analyses were performed by western blot and ELISA. IF identified ECE-1 expression within the stroma and villous space. Cellular localization of ECE-1 was limited to endothelial membranes. There was significantly less ECE-1 in preeclamptic placentas, suggesting ECE-1 is important for proper regulation of ET-1 within the placenta.
