Correlation between VEGFR2 rs2071559 polymorphism and glioma risk among Chinese population.

ABSTRACT:

Objective

We investigated the correlation between vascular endothelial growth factor 2 (VEGFR2) polymorphism and glioma risk among Chinese population.

Method

Case-control study design was adopted, and blood samples and clinical data of 250 glioma cases and 260 control subjects were collected. Epidemiological questionnaire survey was performed, and DNA extraction, concentration normalization and packaging were carried out using Qiagen Blood Kit. TaqMan method was performed for VEGFR2 rs2071559 genotyping.

Results

C allele of VEGFR2 rs2071559 genotype was the susceptibility allele contributing to the risk of glioma (OR=1.813, 95% CI: 1.393-2.359, P=0.014). CC genotypes of VEGFR2 rs2071559 were associated with increased risk of glioma (OR=2.068, 95% CI: 1.164-3.674, P=0.014; Adjusted OR=1.883, 95% CI: 1.430~3.013, P=0.018).

Conclusion

CC genotypes of VEGFR2 rs2071559 were associated with glioma risk among Chinese population. However, the role of VEGFR2 rs2071559 polymorphism in glioma susceptibility remains to be further clarified.

Project description:BackgroundEpidermal growth factor (EGF) is critical in cancer process. EGF and EGF receptor (EGFR) interaction plays a pivotal role in cell proliferation, differentiation, and tumorigenesis of epithelial tissues. Variations of the EGF +61G/A (rs4444903) may lead to an alteration in EGF production and/or activity, which can result in individual susceptibility to brain glioma. The purpose of this study was to investigate the potential association between EGF +61G/A and brain glioma in a Chinese population.MethodsIn this study, we analyzed single nucleotide polymorphism of EGF +61G/A in 677 patients with glioma and 698 gender- and age-matched controls. Genotyping was performed by polymerase chain reaction-ligation detection reaction (PCR-LDR) method.ResultsThe A allele (minor Allele) was 33.0% in cases and 27.3% in controls. The additive model was more powerful to reveal the association in our study than that of recessive and dominant model. Our data showed the genotype G/A and A/A was associated with increased risk for glioma (adjusted OR = 1.48, 95%CI: 1.17-1.87, p = 0.001 for G/A, adjusted OR = 1.81, 95%CI: 1.20-2.72, p = 0.005 for A/A, respectively), and for glioblastoma (adjusted OR = 1.51, 95%CI: 1.06-2.17, p = 0.024 and adjusted OR = 2.35, 95%CI: 1.34-4.15, p = 0.003, respectively). The A allele significantly increased glioma risk (OR = 1.31, 95%CI: 1.11-1.55, p = 0.001). The additive model (G/G vs G/A vs A/A) showed that both G/A and A/A genotype increased glioma risk (adjusted OR = 1.40, 95% CI: 1.17-1.66, p = 0.0002).G/A and A/A genotypes or EGF +61 A allele increased risk in both low and high WHO grade glioma. Non-smokers with G/A and A/A genotype showed increased glioma risk compared with G/G genotype (adjusted OR = 1.72, 95%CI: 1.29-2.30, p = 0.0002 and adjusted OR = 1.81, 95%CI: 1.10-2.99, p = 0.020, respectively). This association was not found in ever- or current-smokers.ConclusionsOur study indicated that G/A and A/A genotypes or EGF +61 A allele were associated with higher glioma risk in Chinese. This is in contrast with previous studies which reported G allele as a risk factor of glioma in Caucasian. The role of EGF +61 A/G polymorphism in glioma susceptibility needs further investigation.
