Once cancer is initiated, the cells immediately begin to secrete several factors such as vascular endothelial growth factor (VEGF), transformative growth factor (TGF), metalloproteinase 2 and angiopoietin-1 (Ang-1) that promote the formation of the new vessels which permit cells to have nutrients, blood, and energy and thus escape chemotherapies [8]. This evidence concerns the gene VEGFA and cancer.
