1 Incadronate amplifies prostaglandin F2 alpha-induced vascular endothelial growth factor synthesis in osteoblasts. Dinoprost vascular endothelial growth factor A Mus musculus
2 In the present study, we investigated the mechanism of vascular endothelial growth factor (VEGF) synthesis induced by PGF2 alpha and the effect of incadronate on the VEGF synthesis in these cells. Dinoprost vascular endothelial growth factor A Mus musculus
3 In the present study, we investigated the mechanism of vascular endothelial growth factor (VEGF) synthesis induced by PGF2 alpha and the effect of incadronate on the VEGF synthesis in these cells. Dinoprost vascular endothelial growth factor A Mus musculus
4 PGF2 alpha significantly stimulated the VEGF synthesis in a dose-dependent manner between 1 pm and 10 microm. Dinoprost vascular endothelial growth factor A Mus musculus
5 PGF2 alpha increased the levels of mRNA for VEGF. Dinoprost vascular endothelial growth factor A Mus musculus
6 Indomethacin, an inhibitor of cyclooxygenase, significantly reduced the PGF2 alpha-induced VEGF synthesis. Dinoprost vascular endothelial growth factor A Mus musculus
7 Bisindolylmaleimide, an inhibitor of PKC, reduced the PGF2 alpha-induced VEGF synthesis. Dinoprost vascular endothelial growth factor A Mus musculus
8 The VEGF synthesis induced by PGF2 alpha was significantly attenuated in the PKC down-regulated cells. Dinoprost vascular endothelial growth factor A Mus musculus
9 PD98059 or U0126, inhibitors of MEK, suppressed the VEGF synthesis induced by PGF2 alpha. Dinoprost vascular endothelial growth factor A Mus musculus
10 Incadronate enhanced the synthesis of VEGF induced by PGF2 alpha. Dinoprost vascular endothelial growth factor A Mus musculus
11 PD98059 suppressed the enhancement by incadronate of PGF2 alpha-induced VEGF synthesis. Dinoprost vascular endothelial growth factor A Mus musculus
12 These results strongly suggest that PGF2 alpha stimulates VEGF synthesis through the PKC-dependent activation of p44/p42 MAPK in osteoblasts and that the incadronate enhances the VEGF synthesis at the point between PKC and Raf-1. Dinoprost vascular endothelial growth factor A Mus musculus
