Vascular endothelial growth factor (VEGF)-A-driven angiogenesis contributes to various disorders including cancer and proliferative diabetic retinopathy (PDR). Among several VEGF-A blockers clinically used is aflibercept, a chimeric VEGFR1/VEGFR2-based decoy receptor fused to the Fc fragment of IgG1 (i.e., VEGFR1/VEGFR2-Fc). Here, we revealed a novel anti-angiogenic function for aflibercept bey...
The molecular mechanisms that control the balance between antiangiogenic and proangiogenic factors and initiate the angiogenic switch in tumors remain poorly defined. By combining chemical genetics with multimodal imaging, we have identified an autocrine feed-forward loop in tumor cells in which tumor-derived VEGF stimulates VEGF production via VEGFR2-dependent activation of mTOR, substantially...
BACKGROUND This study aimed to explore the correlation between FGFR1 and clinical features, including survival analysis and the promotion of angiogenesis by fibroblast growth factor receptor 1 (FGFR1) and vascular endothelial growth factor receptor 2 (VEGFR2). FGFR1 gene amplification has been found in non-small cell lung cancer (NSCLC). However, the prognostic value of FGFR1 and the correlatio...
Objective. We discuss the influence of anger emotional stress upon VEGF/VEGFR2 and its induced PI3K/AKT/mTOR signal pathway. Methods. We created a rat model of induced anger (anger-out and anger-in) emotional response using social isolation and resident-intruder paradigms and assessed changes in hippocampus' VEGF content, neuroplasticity, and the PI3K/AKT/mTOR signaling pathway. Results. The re...
Vascular endothelial growth factor (VEGF) is considered one of the main molecules involved in tumor angiogenesis and is largely expressed in oral squamous cell carcinoma (OSCC). His signal is transmitted intracellulary by binding with class III tyrosine kinase receptors, known as VEGF receptor family (VEGFRs). Therefore, we designed this study for quantification of VEGFR1 and VEGFR2 immunohisto...
Arbiser JL. Efficacy of topical application of eosin for ulcer-ated hemangiomas.macologic blockade of Angiopoietin-2 is efficacious against model hemangiomas in mice. In this issue of Blood, Jiang et al identify the cell adhesion molecule CD146 as novel co-receptor for vascular endothelial growth factor receptor 2 (VEGFR2). 1 T he cell adhesion molecule CD146 was first described in 1987 because...
Hantaviruses predominantly infect human endothelial cells and, in the absence of cell lysis, cause two diseases resulting from increased vascular permeability. Andes virus (ANDV) causes a highly lethal acute pulmonary edema termed hantavirus pulmonary syndrome (HPS). ANDV infection enhances the permeability of endothelial cells in response to vascular endothelial growth factor (VEGF) by increas...
Vascular endothelial growth factor (VEGF) is a major growth factor for developing endothelial cells (ECs). Embryonic lethality due to haploinsufficiency of VEGF in the mouse highlighted the strict dose dependency of VEGF on embryonic vascular development. Here we investigated the dose-dependent effects of VEGF on the differentiation of ES cell-derived fetal liver kinase 1 (Flk-1)/VEGF receptor ...
OBJECTIVE Previous studies have shown that oxidized products of PAPC (Ox-PAPC) regulate cell transcription of interleukin-8, LDL receptor, and tissue factor. This upregulation takes place in part through the activation of sterol regulatory element-binding protein (SREBP) and Erk 1/2. The present studies identify vascular endothelial growth factor receptor 2 (VEGFR2) as a major regulator in the ...
The role of cancer stem cells (CSCs) in inducing the recurrence of hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA) remains unclear. Here, we found that a dramatic increase in plasma vascular endothelial growth factor (VEGF) and an induction of local CD133+ CSCs are associated with early HCC recurrence, suggesting that VEGF expression and tumour stemness contribute to the rela...
