Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...

introduction: acute myeloid leukemia is a malignant transformation of hematopoietic tissue, bone marrow infiltration of undifferentiated cells known as blasts that interfere with the production of normal cells. vascular endothelial growth factor (vegf) is persistently secreted from myeloid cells and high levels can be detected in patients' serum. methods: twenty-one aml patients, who were chemo...

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 ...

Specific proteolytic cleavages turn on, modify, or off the activity of vascular endothelial growth factors (VEGFs). Proteolysis is most prominent among lymph­angiogenic VEGF-C and VEGF-D, which are synthesized as precursors that need to undergo enzymatic removal their C- N-terminal propeptides before they can activate receptors. At least five different proteases mediate activating cleavage VEGF...

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 ...

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...

Objective(s): Vascular endothelial growth factor (VEGF) is one of the most effective proteins in angiogenesis, mesenchymal stem cells (MSCs) differentiation and wound healing. These abilities are therapeutic potential of VEGF in diabetic retinopathy, nephropathy and other tissue damage circumstances. In this study, recombinant VEGF was produced in Escherichia coli (E. coli) system and then biol...
