Abstract:
:The effect of alpha-tocopherol on various endothelial cell functions was evaluated in vitro using cultures of human umbilical vein endothelial cells. Prostacyclin synthesis, plasminogen activator activity and von Willebrand factor activity were evaluated in control and alpha-tocopherol supplemented cultures. Alpha-tocopherol produced stimulation of prostacyclin production which peaked at or near 0.5 mM. Plasminogen activator activity was markedly reduced by the addition of alpha-tocopherol. Von Willebrand factor activity showed a significant decrease of processed and cellular forms that was dose-dependent. The incorporation of alpha-tocopherol into endothelial cells could be demonstrated by measuring intracellular levels of the vitamin in washed endothelial cells. Our results show that alpha-tocopherol has a profound effect on multiple endothelial cell functions which are intimately involved in hemostasis.
