Increased vascular endothelial growth factor (VEGF) biosynthesis in vascular endothelial cells has been reported to play an obligatory role in promoting angiogenesis. Nevertheless, the intracellular signaling mechanisms of hypoxia-induced VEGF release remain largely unknown. Human umbilical vein endothelial cell lines (ECV304) were cultured in normoxic or hypoxic conditions for 12-24 h and harvested for determination of VEGF mRNA expression and phosphorylation of ERKl/2 and p38 mitogen-activated protein kin...
