BACKGROUND The circulating concentration of PlGF is reported to be lower in patients experiencing preeclampsia and patients delivering a small for gestational age (SGA) neonate. To evaluate the predictive value of circulating PlGF for preeclampsia and adverse outcome in patients with suspected preeclampsia or intrauterine growth restriction (IUGR). METHODOLOGY/PRINCIPAL FINDINGS A double blin...

Purpose: MNRP1685A is a monoclonal antibody to neuropilin-1 (NRP1). We evaluated blood-based pharmacodynamic biomarkers of MNRP1685A in two phase I studies to assess exposure/response relationships to inform target dose and regimen selection. Experimental Design: The phase I studies evaluated escalating doses ofMNRP1685A as a single agent or in combination with bevacizumab. Plasma placental gro...

In adult bone marrow, mature erythroblasts are produced within structures called erythroblastic islands and then cross the endothelial barrier to reach circulation. Erythroblastic islands are composed of a central macrophage surrounded by maturing erythroblasts. In this study, it is shown that erythroid cells, but not the other mature hematopoietic cells, coexpress 2 angiogenic factors, vascula...

Reduced placental growth factor (PlGF) levels and higher soluble fms-like tyrosine kinase (sFlt-1) levels in mothers during pregnancy may have persistent effects on vascular structures in their offspring. We examined whether angiogenic factors during pregnancy also affect childhood retinal microvasculature in a population-based prospective cohort study among 3505 mothers and their children. We ...

OBJECTIVE To investigate whether angiogenic factors are associated with risk of developing preeclampsia in pregnant women with systemic lupus erythematosus (SLE). METHODS We performed a nested case-control study within a cohort of SLE women with singleton pregnancies. The study included 42 patients with SLE who eventually developed preeclampsia and 75 normal SLE pregnancies. Serum samples wer...

Recent data have indicated a relationship between placental oxygen and angiogenic protein levels in the first trimester of normal pregnancies. Our objective was to investigate if maternal serum levels of angiogenic factors Soluble vascular endothelial growth factor (VEGF) receptor 1 (sFlt-1), soluble Endoglin and placental growth factor (PlGF) are altered in women with symptoms of threatened mi...

OBJECTIVE To investigate the potential value of maternal serum concentrations of free β-human chorionic gonadotrophin (β-hCG), pregnancy-associated plasma protein-A (PAPP-A) and placental growth factor (PlGF) at 30-33 weeks of gestation in the prediction of pre-eclampsia (PE) developing at or after 34 weeks. METHODS Serum free β-hCG, PAPP-A and PlGF were measured at 11-13 and at 30-33 weeks o...

PURPOSE To evaluate changes in the concentrations of placental growth factor (PlGF) and vascular endothelial growth factor-A (VEGF-A) in aqueous humor of patients with neovascular glaucoma (NVG) before and after an intravitreal injection of ranibizumab (IVR) and to determine the underlying correlation between the levels. METHODS The prospective interventional comparative study involved 20 eye...
