“…Vascular endothelial growth factor (VEGF), a signal protein produced by cells, stimulates vasculogenesis and angiogenesis (Yancopoulos et al, 2000;Ferrara et al, 2003;Ferrara et al, 2004;Harris et al, 2002). The over-expression of VEGF is a possible predictor of cancers (Keyes et al, 2004;Granato et al, 2004;Enjoji et al, 2005;Ławicki et al, 2013;Dalaveris et al, 2009;Slaton et al, 2001;Hyodo et al, 1998;Takiuchi et al, 2000). For example, patients with breast, ovarian, and lung cancer contains higher levels of VEGF than healthy individuals (Granato et al, 2004;Enjoji et al, 2005;Ławicki et al, 2013;Dalaveris et al, 2009).…”
