1 Platelet-derived growth factor-BB amplifies PGF2alpha-stimulated VEGF synthesis in osteoblasts: function of phosphatidylinositol 3-kinase. Dinoprost vascular endothelial growth factor A Mus musculus
2 We have reported that prostaglandin F2alpha (PGF2alpha) stimulates the synthesis of vascular endothelial growth factor (VEGF) via p44/p42 mitogen-activated protein (MAP) kinase in osteoblast-like MC3T3-E1 cells. Dinoprost vascular endothelial growth factor A Mus musculus
3 We have reported that prostaglandin F2alpha (PGF2alpha) stimulates the synthesis of vascular endothelial growth factor (VEGF) via p44/p42 mitogen-activated protein (MAP) kinase in osteoblast-like MC3T3-E1 cells. Dinoprost vascular endothelial growth factor A Mus musculus
4 We have reported that prostaglandin F2alpha (PGF2alpha) stimulates the synthesis of vascular endothelial growth factor (VEGF) via p44/p42 mitogen-activated protein (MAP) kinase in osteoblast-like MC3T3-E1 cells. Dinoprost vascular endothelial growth factor A Mus musculus
5 We have reported that prostaglandin F2alpha (PGF2alpha) stimulates the synthesis of vascular endothelial growth factor (VEGF) via p44/p42 mitogen-activated protein (MAP) kinase in osteoblast-like MC3T3-E1 cells. Dinoprost vascular endothelial growth factor A Mus musculus
6 In the present study, we investigated the effect of PDGF-BB on the PGF2alpha-induced VEGF synthesis in MC3T3-E1 cells. Dinoprost vascular endothelial growth factor A Mus musculus
7 PDGF-BB, which alone did not affect the levels of VEGF, significantly enhanced the PGF2alpha-stimulated VEGF synthesis. Dinoprost vascular endothelial growth factor A Mus musculus
8 PD98059, a specific inhibitor of MEK1/2, suppressed the amplification by PDGF-BB of the PGF2alpha-stimulated VEGF synthesis similar to the levels of PGF2alpha with PD98059. Dinoprost vascular endothelial growth factor A Mus musculus
9 These results strongly suggest that PGF2alpha-stimulated VEGF synthesis is amplified by PI3-kinase-mediating PDGF-BB signaling in osteoblasts, and that the effect is exerted at a point downstream from p44/p42 MAP kinase. Dinoprost vascular endothelial growth factor A Mus musculus
