Overall, while the genetic variations in the VEGF and MMP genes are attractive candidates as prognostic markers, our study showed no evidence of associations of a large set of SNPs in these genes and overall survival of colorectal cancer patients in our study.
The aim of this study was to investigate the association between the risk for colorectal cancer and single nucleotide polymorphisms (SNP) of matrix metalloproteinase-2 (MMP2) -1306C/T, vascular endothelial growth factor (VEGF) 936C/T and hypoxia inducible factor-1α (HIF1A) 1772C/T.
Interplay between 3'-UTR polymorphisms in the vascular endothelial growth factor (VEGF) gene and metabolic syndrome in determining the risk of colorectal cancer in Koreans.
Angiogenic and Antiangiogenic VEGFA Splice Variants in Colorectal Cancer: Prospective Retrospective Cohort Study in Patients Treated With Irinotecan-Based Chemotherapy and Bevacizumab.
Our meta-analysis indicated that VEGF-2578C/A polymorphism was associated with the risk of colorectal cancer under homozygote comparison (OR=0.70, 95% CI=0.53-0.92), dominant model (OR=0.72, 95% CI=0.57-0.92), and recessive model (OR=0.82, 95% CI=0.67-1.01), although no evidence of association between VEGF-2578C/A polymorphism and cancer risk was observed as we compared in the pooled analyses (homozygote comparison: OR=0.97, 95% CI=0.81-1.16).
We analyzed VEGF (-2578C>A, -1498C>T, -1154G>A, -634C>G, +936C>T) and eNOS (+894G>T, -786T>C, VNTR (variable number of tandem repeats) 27bp intron 4) polymorphisms by direct sequencing or Real Time PCR in 237 patients with advanced colorectal cancer.
