Background: Vascular endothelial growth factor-A (VEGF-A), an endothelial cell-specific mitogen produced by various cell types, plays important roles in cell differentiation and proliferation. In this study we investigated the effect of recombinant VEGF-A on differentiation of mesenchymal stem cells (MSCs) to endothelial cells (ECs). Methods: VEGF-A was expressed in E. coli BL21 (DE3) and BL21...

Background: The pathogenesis of many diseases is correlated to irregularity in vascular endothelial growth factor (VEGF) expression. Results from several association studies show that variation in the level of VEGF expression is related to polymorphic sequences within the VEGF gene. Additionally, there are many studies showing that some gene polymorphisms significantly influence the pharmacokin...

Background:Oral lichen planus (OLP) is considered as a potentially malignant disorder and vascular endothelial growth factor (VEGF) may play a key role in cancer development. The aim of this study was to compare serum and saliva VEGF among patients with OLP, oral squamous cell carcinoma (OSCC) and a healthy control group. Methods:A cross sectional study was pe...

Background: There is a direct correlation between ocular vascular endothelial growth factor (VEGF) level and progression of pathological outcomes in diabetic retinopathy. In our previous study, the periocular administration of propranolol and celecoxib could significantly reduce ocular VEGF levels in a diabetic mouse model. Here, we investigated the changes of serum VEGF after ...

آنژیوژنز فرایندی است که در طی آن رگ های خونی جدید در بدن تشکیل می شود. تشکیل رگ های جدید در یک تومور سرطانی باعث می شود مواد غذایی و اکسیژن بیشتری به سلول های تومور رسیده و تومور از حالت توده ی سلول های جهش یافته و بی ضرر تبدیل به یک تومور بدخیم شود. این تومور می تواند به بافت های دیگر حمله نموده و منجر به متاستاز شود. یکی از مهم ترین عوامل آنژیوژنز در بدن فاکتور رشد اندوتلیال رگی (vegf) می باش...

background and objective: vascular endothelial growth factor (vegf) is a cytokine which is overexpressed in many malignant cancers including leukemia. vegf plays an important role in tumor invasion and metastasis. determination of the pattern of vegf expression in human leukemic cell lines could be useful not only in screening of new antileukemic agents but also to study the mechanism of their ...

Objective(s): Lung cancer is the main leading cause of cancer death worldwide. Angiogenesis is the main step in proliferation and spreading of tumor cells. Targeting vascular endothelial growth factor (VEGF) is an effective approach for inhibition of cancer angiogenesis. Nanobodies (NBs) are a novel class of antibodies derived from the camel. Unique characteristics of Nbs like their small size ...
