Vascular endothelial growth factors (VEGFs) and their receptors (VEGFRs) are key drivers of blood and lymph vessel formation in development, but also in several pathological processes. VEGF-C signaling through VEGFR-3 promotes lymphangiogenesis, which is a clinically relevant target for treating lymphatic insufficiency and for blocking tumor angiogenesis and metastasis. The extracellular domain...

Objective: To assess the inhibition activity of sesquiterpene lactones from Vernonia amygdalina Delile as a new anticancer potential on expression cancer therapeutic target-proteins, namely: epidermal growth factor receptor (EGFR), and vascular endothelial (VEGFR). Methods: The in silico screening, target‐based approach (docking) was performed by Prediction Activity Spectra for Substances (PASS...

Pheochromocytoma (PHEO), a rare catecholamine producing tumor arising from the chromaffin cells, may occurs sporadically (76%-80%) or as part of inherited syndromes (20%-24%). Angiogenesis is a fundamental step in tumor proliferation and vascular endothelial growth factor (VEGF-A) is the most well-characterized angiogenic factor. The role of angiogenic markers in PHEO is not fully understood; i...

preeclampsia is an important pregnancy disorder with serious maternal and fetal complications which its etiology has not been completely understood yet. early diagnosis and management of disease could reduce its potential side effects. the vascular endothelial growth factor (vegf) family including vegf-a is the most potent endothelial growth factor which induces angiogenesis and endothelial cel...

Angiogenesis is essential for endometrial growth and repair, and disruption of this process may lead to common gynecological disorders, including menorrhagia and endometriosis. We have recently shown that expression of vascular endothelial growth factor (VEGF)-A and its two main receptors, VEGFR-1 and -2, is increased in idiopathic menorrhagia (IM). The aim of this study was to determine the ex...

Background—Lymphatic network and chemokine-mediated signals are essential for leukocyte traffic during the proximal steps of alloimmune response. We aimed to determine the role of lymphatic vessels and their principal growth signaling pathway, vascular endothelial growth factor (VEGF)-C/D/VEGFR-3, during acute and chronic rejection in cardiac allografts. Methods and Results—Analysis of heteroto...

Vascular endothelial growth factor (VEGF), its receptors (VEGFR-1, VEGFR-2) and neuropillin-1 (NRP-1) are expressed at variable levels in bone marrow. NRP-1expression is higher in fatty bone marrow than in hematopoietic marrow. Adipocytes are responsible for NRP-1 expression suggesting that they may play a role in hematopoiesis by producing NRP-1 or that NRP-1 may regulate adipocyte activity.

Vascular endothelial growth factor (VEGF) receptor tyrosine kinase inhibitor (VEGFR-TKI), an oral molecular targeted drug, reportedly causes serious adverse cardiovascular events such as hypertension and left ventricular failure. The association between VEGFR-TKI-induced heart failure with preserved ejection fraction (LVEF) (HFpEF) has been previously studied. Therefore, we investigated the rel...

The angiogenic response of endothelial cells initiated by different growth factors is accompanied by assembly of cell surface-bound proteolytic machinery as a prerequisite for focal invasion. We have shown previously how the vascular endothelial growth factor (VEGF) initiates proteolysis by activation of pro-urokinase (pro-PA) via the VEGF receptor-2 (VEGFR-2). We now show that the cell surface...
