BACKGROUND Vascular endothelial growth factor (VEGF) has been investigated as a marker of ovarian response to controlled ovarian hyperstimulation and as a predictor of ovarian hyperstimulation syndrome (OHSS) in IVF cycles. In most studies, serum has been used for circulating VEGF concentration measurement, but it has been suggested that plasma is the preferred medium to measure VEGF levels bec...

background: stimulation of collateral artery growth (arteriogenesis) and/or capillary network growth (angiogenesis) would be beneficial to the patients with myocardial infarction. to understand the central role of vascular endothelial growth factor (vegf) in biological angiogenesis, we performed molecular analysis of the vegf gene in patients afflicted with acute myocardial infarction (ami).   ...

The POEMS syndrome is associated with elevated vascular endothelial growth factor (VEGF) levels. Several studies have compared serum VEGF levels between POEMS patients and other disease entities showing higher serum VEGF in POEMS syndrome; however, it is unknown whether serum levels are reliable and reproducible given variable platelet release of VEGF. We therefore compared plasma levels of VEG...

OBJECTIVE The aim of this study was to evaluate the potential prognostic value of the circulating levels of vascular endothelial growth factor-A (VEGF-A) in patients with gastric cancer. MATERIALS AND METHODS An ELISA was used to quantify the serum and plasma levels of VEGF-A in 135 patients with gastric cancer and 48 controls with benign gastric diseases diagnosed by gastroendoscopy and hist...

BACKGROUND A preliminary animal study was performed to determine if hepatic micrometastases from uveal melanoma secrete vascular endothelial growth factor (VEGF) that is measurable in serum. METHODS We analysed the serum of a C57Bl/6 mouse model of uveal melanoma (n=10) at days 4, 7, 14 and 21 post-inoculation for VEGF levels. We compared the serum VEGF levels with the number and location of ...

BACKGROUND Vascular endothelial growth factor (VEGF) is a mediator with potent angiogenic, mitogenic, and vascular permeability-enhancing activities that are specific for endothelial cells. Intense angiogenesis has been found in active pulmonary tuberculosis lesions. OBJECTIVES To determine whether active pulmonary tuberculosis is associated with increased serum levels of VEGF compared with i...

Background: Stimulation of collateral artery growth (arteriogenesis) and/or capillary network growth (angiogenesis) would be beneficial to the patients with myocardial infarction. To understand the central role of vascular endothelial growth factor (VEGF) in biological angiogenesis, we performed molecular analysis of the VEGF gene in patients afflicted with acute myocardial infarction (AMI). Me...

PURPOSE Angiogenesis is essential for tumor growth. Vascular endothelial growth factor (VEGF) is one of the most potent angiogenic cytokines. In breast cancer, tumor VEGF has been shown to have a good correlation with relapse-free survival. The aim of this study was to determine the relation of serum VEGF levels to the various indices of breast cancer and known tumor markers carcinoembryonic an...

Recent studies have suggested that serum levels of vascular endothelial growth factor (VEGF) may provide useful prognostic information in patients with various types of cancers. However, there has been a debate on whether serum VEGF level is a true reflection of tumor angiogenic activity in cancer patients. This debate originates from the finding that most VEGF in the serum is released from pla...

Most studies measuring circulating vascular endothelial growth factor (VEGF) have sampled serum rather than plasma. There has been much debate whether the collection of sera (which causes the activation of platelets and VEGF release) is a true reflection of tumor angiogenic activity or whether platelets act as scavengers of VEGF. Addressing this issue, we measured serum and plasma VEGF, before ...
