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 ...

Downlo ors induce new blood vessel growth primarily from host organ microvascular endothelial cells (EC), and vasculature differs significantly between the lung and liver. Vascular endothelial growth factor (VEGF GF-A) promotion of tumor angiogenesis is thought to be mediated primarily by VEGF receptor-2 R-2). In this study, VEGFR-2 antibody (DC101) inhibited growth of RenCa renal cell carcinom...

Oxygen administration to immature neonates suppresses VEGF-A expression in the retina, resulting in the catastrophic vessel loss that initiates retinopathy of prematurity. To investigate the mechanisms responsible for survival of blood vessels in the developing retina, we characterized two VEGF-A receptors, VEGF receptor-1 (VEGFR-1, also known as Flt-1) and VEGF receptor-2 (VEGFR-2, also known ...

vascular endothelial growth factor receptor-2 (vegfr-2); a cell surface receptor for vascular endothelial growth factors, is a key pharmacological target involved in the cell proliferation/angiogenesis. it has been revealed that vegfr-2 induces proliferation through activation of the extracellular signal-regulated kinases pathway. in this regard, targeting the vegfr-2 has been considered as an ...

Vascular endothelial growth factor (VEGF)/vascular permeability factor induces both angiogenesis and vascular permeability mainly through VEGF receptor (VEGFR)-2 activation. VEGF binds VEGFR-1 as well, but the importance of VEGFR-1 signaling in vascular permeability has been largely neglected. Here, we report the purification and characterization of a novel VEGF-like protein from Trimeresurus f...

VEGF-A is the most potent angiogenic factor in tumour angiogenesis. Its effects are mediated via two receptors VEGFR-1 and VEGFR-2. Primary aim of our study was to examine the expression of VEGFR-1 in breast cancer and its correlation to VEGF expression, lymph node status, tumour size, histological grade, and hormone receptor status. To examine the VEGFR-1 and VEGF expressions in tumour and sur...

BACKGROUND Glioblastoma (GBM) is a highly migratory, invasive, and angiogenic brain tumor. Like vascular endothelial growth factor-A (VEGF-A), placental growth factor (PlGF) promotes GBM angiogenesis. VEGF-A is a ligand for both VEGF receptor-1 (VEGFR-1) and VEGFR-2, while PlGF interacts exclusively with VEGFR-1. We recently generated the novel anti-VEGFR-1 monoclonal antibody (mAb) D16F7 that ...

Estrogen is involved in breast tumorigenesis, but the precise mechanisms for its oncogenic and angiogenic actions are poorly understood. Angiogenesis is regulated, in part, by these critical components: vascular endothelial growth factor (VEGF) and its two receptors (VEGFR-1 and VEGFR-2). VEGFR-2 is a positive angiogenic signal transducer, whereas VEGFR-1, especially its soluble form (soluble V...

Although potential contribution of endothelial progenitor cells (EPCs) to angiogenesis in glioma has been proposed, the molecular mechanisms of EPCs recruitment to vasculature have not been fully elucidated. Here, we show that the supernatant from glioma cells promotes EPCs angiogenesis via VEGFR-2, not VEGFR-1. Moreover, VEGFR-2 siRNA inhibits VEGFR-2 expression in EPCs, tube formation on matr...
