Effect of 20-hydroxyeicosatetraenoic acid on biological behavior of human villous trophoblasts and uterine vascular smooth muscle cells.

During pregnancy, disorders in uterine spiral artery remodeling (USAR) cause preeclampsia and other diseases. The aim of this study was to investigate the effect of 20-hydroxyeicosatetraenoic acid (20-HETE) on the biological behavior of human villous trophoblasts (HVTs) and human uterine vascular smooth muscle cells (HUVSMCs), and explore the role of 20-HETE in USAR. 20-HETE and its inhibitor HET0016 were used to study migration, invasion and apoptosis in the HVT and HVT-HUVSMC models. 20-HETE inhibited the migration and invasion of HVTs, and inhibited apoptosis in HUVSMCs and HUVSMCs co-cultured with HVTs. 20-HETE had thus obvious effects on the biological behavior of HVTs and HUVSMCs. These effects may cause USAR disorders and vascular dysfunction, leading to preeclampsia.
