We hypothesized that epidermal growth factor (EGF) receptor (EGFR) activation and vascular endothelial growth factor (VEGF)-induced angiogenic signals are important for the progression and metastasis of human salivary adenoid cystic carcinoma (ACC). To test this hypothesis, we evaluated the therapeutic effect of AEE788, a dual inhibitor of EGF and VEGF receptor (VEGFR) tyrosine kinases, on huma...

OBJECTIVE Plasminogen activator inhibitor-1 (PAI-1) regulates angiogenesis via effects on extracellular matrix proteolysis and cell adhesion. However, no previous study has implicated PAI-1 in controlling vascular endothelial growth factor (VEGF) signaling. We tested the hypothesis that PAI-1 downregulates VEGF receptor-2 (VEGFR-2) activation by inhibiting a vitronectin-dependent cooperative bi...

BACKGROUND The epidermal growth factor receptor (EGFR) and vascular endothelial growth factor receptor (VEGFR) have been implicated as therapeutic targets for head and neck squamous cell carcinoma (HNSCC). Vandetanib is a small-molecule tyrosine kinase inhibitor (TKI) with dual specificity for EGFR and VEGFR. Here we characterize the phenotypic and biochemical effects of vandetanib on various H...

OBJECTIVES Expression of vascular endothelial growth factor C (VEGF-C)and vascular endothelial growth factor receptor-3 (VEGFR-3) in laryngeal squamous carcinoma and its relationship to lymph node metastasis were investigated. METHODS VEGF-C and VEGFR-3 gene expression in 30 cases of normal laryngeal mucosa tissue (NLM), primary laryngeal carcinoma cell carcinomas (PLC) and cervical lymph nod...

Anti-angiogenesis is the therapeutic strategy designed to disrupt vascular supply and starve tumors of nutrients oxygen. This achieved mainly by blocking endothelial growth factor (VEGF) actions, as VEGF signaling pathway considered main angiogenesis promoter active in tumor microenvironment (TME) under hypoxic conditions. A total 16 anti-angiogenic agents, including anti-VEGF antibodies, recep...

OBJECTIVE Vascular endothelial growth factor receptor(VEGFR)-3 is a critical regulator of developmental and adult vasculogenesis and lymphangiogenesis through its interactions with select members of the VEGF family. The goal of this study was to investigate how VEGFR-3 expression is regulated during inflammatory lymphangiogenesis. METHODS AND RESULTS In this study, we present for the first ti...

Vascular endothelial cells are characterized by a high degree of functional and phenotypic plasticity, which is controlled both by their pericellular microenvironment and their intracellular gene expression programs. To gain further insight into the mechanisms regulating the endothelial cell phenotype, we have compared the responses of lymphatic endothelial cells (LECs) and blood vascular endot...

background and objectives: angiogenesis is essential for growth and metastasis of solid malignancies. tumor vessel count and expression of vascular endothelial growth factor (vegf), a potent angiogenic factor, have been associated with prognosis. this study was designed to assess vessels density by using cd31 and cd105 (endoglin) and their correlation with expression of vegf and proliferative i...

background: the effects of the vascular endothelial growth factor (vegf) gene ?2578c/a polymorphism on colorectal cancer (crc) risk have been investigated in some studies; however, the results of these studies were conflicting and ambiguous. therefore, we aimed to do a meta-analysis to investigate the association of vegf ?2578c/a polymorphisms with crc risk from all eligible case-control studie...
