OBJECTIVES Morphological changes of blood vessel wall have been described in placenta from pregnancies complicated by diabetes mellitus type-I. STUDY DESIGN We measured mRNA expression of vascular endothelial growth factor (VEGF), angiopoietin 1 and 2 (Ang-1 and Ang-2), their receptors VEGFR-1, VEGFR-2, Tie-2, fibroblast growth factor 2 (FGF-2), and its receptor FGF-2R in placental tissue of ...

INTRODUCTION Vascular endothelial growth factor (VEGF) is expressed in osteoarthritic articular cartilage. However, the pattern of VEGF expression throughout the whole life cycle of articular cartilage is not well elucidated. The aim of the study was to investigate the spatiotemporal expression of VEGF and its receptors, vascular endothelial growth factor receptor-1 (VEGFR1) and vascular endoth...

BACKGROUND Heparin affin regulatory peptide (HARP) is an 18-kDa secreted protein that has been implicated in tumor growth and angiogenesis, although the mechanisms involved remain largely unknown. In the present work, the effect of human recombinant HARP on the expression of the vascular endothelial growth factor (VEGF) receptors KDR, Flt-1 and neuropilin-1 was studied in cultured human umbilic...

BACKGROUND Breast angiosarcoma is rare and often associated with previous breast cancer treatment. The present study aimed to define long-term outcomes in relation to common prognostic factors. The expression of vascular endothelial growth factor receptor was also evaluated, as it may be a potential target for anti-angiogenic therapy. PATIENTS AND METHODS We retrospectively assessed outcomes ...

Vascular endothelial growth factor, VEGF, stimulates angiogenesis by directly acting on endothelial cells. The effects of VEGF are mediated by two tyrosine kinase receptors, VEGFR-1 (Flt-1) and VEGFR-2 (Flk-1/KDR) that are highly related to receptors of the platelet derived growth factor (PDGF) receptor family. We are interested in early signalling events downstream from VEGF receptors that aff...

The different members of the vascular endothelial growth factor (VEGF) family act as key regulators of endothelial cell function controlling vasculogenesis, angiogenesis, vascular permeability and endothelial cell survival. In this study, we have functionally characterized a novel member of the VEGF family, designated VEGF-E. VEGF-E sequences are encoded by the parapoxvirus Orf virus (OV). They...

s:865:"We read with interest the manuscript entitled "Serum and peritoneal fluid levels of vascular endothelial growth factor in women with endometriosis" recently published in the International Journal of Fertility and Sterility (1). The authors measured the levels of vascular endothelial growth factor in serum and peritoneal fluid of 179 women, 90 of whom were diagnosed with endometriosis, an...

background: henoch-schönlein purpura (hsp) is an lga mediated small vessel systemic vasculitis disease in children. the etiology and pathogenesis of hsp disease remain unknown. however, environmental and genetic risk factors could play important roles in susceptibility to hsp disease. in this study we investigated the association of 5՛-untranslated region polymorphism (-634g/c) of vegf gene wit...
