Vascular endothelial growth factor ( VEGF ) and placental growth factor ( PlGF ) are key angiogenic stimulators during normal development and wound healing , as well as in a variety of pathological conditions . ^^^ Recent studies have demonstrated a synergistic effect of VEGF and PlGF in pathological angiogenesis and suggest a role for PlGF in amplifying VEGF action in endothelial cells . ^^^ In cultured human retinal and umbilical vein endothelial cells , VEGF induced the production of PlGF protein by over 10 fold ( P < 0 . 01 ) in a dose dependent manner through a post transcriptional mechanism . ^^^ The increased PlGF expression upon VEGF treatment was significantly reduced by inhibition of the protein kinase C ( PKC ) and MEK signaling pathways , as well as by treatment with the calcium ionophore A 23187 . ^^^ Taken together , our findings demonstrate that VEGF can amplify its effects on endothelial cells by inducing the production of PlGF via a post transcriptional mechanism in a PKC dependent manner , and provide a potential link between PKC inhibition and amelioration of vascular complications in the development of angiogenic diseases . . ^^^

Cell homogenates were incubated with Trans Signal Angiogenesis Antibody Array containing antibodies to angiogenic activators ( ANG , HGF , leptin , VEGF , IL 6 , IL 8 , PIGF , FGF alpha / beta , TNF alpha and TGF alpha ) and inhibitors ( IFN gamma , IL 12 , IP 10 , TIMP 1 and 2 ) . ^^^ Hcy decreased the expression of leptin , IL 6 , 8 , PIGF , FGF alpha and VEGF , while the levels of anti angiogenic IL 12 , IP 10 ( chemokine ) and TIMP 1 were increased by Hcy . ^^^

OBJECTIVE : Accumulating evidence suggests that the balance between vascular endothelial growth factor ( VEGF ) , placental growth factor ( PIGF ) , and their receptors is important for effective vasculogenesis , angiogenesis , and placental development . ^^^ Recently , the soluble form of VEGFR 1 ( sVEGFR 1 ) , an antagonist to VEGF and PIGF , has been implicated in the pathophysiology of pre eclampsia . ^^^
