Autocrine effect of endothelin on DNA synthesis in human vascular endothelial cells.
To elucidate the role of endogenous endothelin on DNA synthesis in endothelial cells, we have investigated the effects of rabbit anti-ET gamma globulin on DNA synthesis in cultured human vascular endothelial cells. DNA synthesis was markedly inhibited by anti-ET gamma globulin in a concentration dependent manner in the presence of fetal calf serum(FCS) (x5000;34%, x2500;54%, x1000;70%), but not in the absence of FCS. These data suggest that endogenous ET modulates FCS-stimulated DNA synthesis in an autocrine fashion.
