Relation of serum vascular endothelial growth factor as an angiogenesis biomarker with nitric oxide & urokinase-type plasminogen activator in breast cancer patients

Abstract

Background & objectives: The primary mediator of angiogenesis is vascular endothelial growth factor (VEGF). It is well documented that angiogenic activity in human cancer depends on nitric oxide (NO) levels in tissues. Additionally, urokinase type plasminogen activator (u-PA) plays a role in cell adhesion and migration. Serum VEGF and its relationship between NO and u-PA concentrations are poorly reported in breast cancer patients. The aim of this study was to investigate the relationship between serum levels of VEGF and NO and u-PA in patients with breast cancer.
