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...
VEGFR-2 plays a critical role in vasculogenesis and inhibitors of VEGFR-2 could be used in the treatment of cancer. Taspine was one of the active ingredients screened by using an endothelial cell membrane chromatography and showed inhibition against VEGFR-2. In our research, we explored how the lactone ring and biphenyl scaffold in taspine influence its potent in vitro anticancer and antiangiog...
Activation of vascular endothelial growth factor receptor-2 (VEGFR-2) plays a critical role in vasculogenesis and angiogenesis. However, the mechanism by which VEGFR-2 activation elicits these cellular events is not fully understood. We recently constructed a chimeric receptor containing the extracellular domain of human CSF-1R/c-fms, fused with the entire transmembrane and cytoplasmic domains ...
Endothelial cell signal transduction mechanisms involved in angiogenesis have come into focus in cancer research when it was realized that solid tumors are dependent on neovascularization (1). Unlike normal human endothelial cells, which are quiescent except in the reproductive organs of fertile women, endothelial cells in tumors express several target features associated with their angiogenic ...
سلول های rpe جداسازی شده از کره های چشم اجساد انسانی در سنین جنینی تا نوزادی که بیش از ?? ساعت از زمان مرگ آنها نگذشته بود از بانک چشم جمهوری اسلامی ایران تهیه شد و در محیط dmem/f12 غنی شده با %10 سرم جنین گوساله (fbs ) کشت شدند. در پاساژهای مشخص سلول ها تحت تاثیر محیط حاوی غلظت های مختلف anti-ctgf و avastin( anti-vegf antibody) قرار گرفته و غلظت های مورد نظر انتخاب و در مرحله پایانی اثر ترکیبی...
Controlled angiogenesis and lymphangiogenesis are essential for tissue development, function, and repair. However, aberrant neovascularization is an essential pathogenic mechanism in many human diseases, including diseases involving tumor growth and survival. Here, we have demonstrated that mice deficient in C-type lectin family 14 member A (CLEC14A) display enhanced angiogenic sprouting and he...
SAR131675 is a potent and selective VEGFR-3 inhibitor. It inhibited VEGFR-3 tyrosine kinase activity and VEGFR-3 autophosphorylation in HEK cells with IC(50) values of 20 and 45 nmol/L, respectively. SAR131675 dose dependently inhibited the proliferation of primary human lymphatic cells, induced by the VEGFR-3 ligands VEGFC and VEGFD, with an IC(50) of about 20 nmol/L. SAR131675 was found to be...
