Here we show that PGD\n                    <jats:sub>2<\/jats:sub>\n                    receptor (DP) deficiency enhances tumor progression accompanied by abnormal vascular expansion. In tumors, angiogenic endothelial cells highly express DP receptor, and its deficiency accelerates vascular leakage and angiogenesis. Administration of a synthetic DP agonist, BW245C, markedly suppresses tumor growth as well as tumor hyperpermeability in WT mice, but not in DP-deficient mice. In a corneal angiogenesis assay and a modified Miles assay, host DP deficiency potentiates angiogenesis and vascular hyperpermeability under COX-2-active situation, whereas exogenous administration of BW245C strongly inhibits both angiogenic properties in WT mice. In an in vitro assay, BW245C does not affect endothelial migration and tube formation, processes that are necessary for angiogenesis; however, it strongly improves endothelial barrier function via an increase in intracellular cAMP production.
