We report that under normoxic conditions, ET(B)R activation by ET-1/ET-3 enhances vascular endothelial growth factor (VEGF) up-regulation, cyclooxygenase (COX)-1/COX-2 protein expression and COX-2 promoter activity, prostaglandin E(2) (PGE(2)) production, and do so to a greater extent under hypoxia.
