VEGF stimulates proliferation, migration and tube formation of endothelial cells in vitro and regulates vascular permeability in vivo (Veikkola and Alitalo, 1999). VEGF expression correlates with angiogenesis and prognosis in various tumours such as breast, lung and malignant mesothelioma (Toi et al, 2001; Strizzi et al, 2001). Various polymorphisms have already been described within the promoter and 5’UTR of your VEGF gene, a few of which (+405 C4G, 71154G4A and 2578C4A) correlate with VEGF production. The +405C, 1154G and 2578C alleles are connected with low VEGF production (Watson et al, 2000; Shahbazi et al, 2002a). Current research have shown that in folks with the 1154 AA genotype, there might be a reduce in prostate cancer risk (McCarron et al, 2002) and reduction in invasive potential of malignant melanomas (Howell et al, 2002). This confirms earlier studies that associate decreased VEGF production with all the 71154A allele. In a different study of healthful individuals, three polymorphisms (702 C4T, 936 C4T and 1612 G4A) were BRD3 web identified inside the 3’UTR area on the VEGF gene.
