Association between MDM2 rs769412 and rs937283 polymorphisms with alcohol drinking and laryngeal carcinoma risk.

ABSTRACT: To investigate the association between the interactions of murine double minute 2 (MDM2) polymorphisms (rs769412 and rs937283) with alcohol drinking and laryngeal carcinoma.Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the genotypes status of MDM2 rs769412 and rs937283 polymorphisms among 126 cases and 120 controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by the chi-squared test, which was adopted to analyze the association between MDM2 rs769412 and rs937283 polymorphisms and the susceptibility to larynx carcinoma in the drinking population.Genotypes distributions of MDM2 rs769412 and rs937283 polymorphisms in the control group were in accordance with Hardy-Weinberg equilibrium (HWE). MDM2 rs769412 GG genotype and G allele significantly increased laryngeal carcinoma risk (GG vs. AA: OR=3.17, 95% CI=1.25-8.04; G vs. A: OR=1.88, 95% CI=1.24-2.84). Furthermore, the mutant genotypes of MDM2 rs937283and rs769412 were remarkablely associated with the increased risk for laryngeal carcinoma in drinking population (rs937283: OR=2.67, 95% CI=1.40-5.07; rs769412: OR=3.76, 95% CI=1.62-8.75).MDM2 polymorphisms are correlated with the onset of laryngeal carcinoma. The relationship is strengthened by alcohol drinking.

Project description:The aim of this study was to investigate the association between polymorphism of the cytochrome P450 1B1 (CYP1B1) gene, a metabolic enzyme gene, and the susceptibility to laryngeal cancer among the Chinese Han population.In a case-control study, we investigated polymorphisms in the CYP1B1 gene (rs10012, rs1056827, and rs1056836) with a real-time quantitative polymerase chain reaction (PCR) assay (TaqMan). The study was conducted with 300 Chinese Han patients with laryngeal cancer and 300 healthy Chinese Han subjects in a control group. We also studied the interactions between genetic polymorphism and risk factors such as smoking and alcohol consumption in the pathogenesis of laryngeal cancer.There were statistically significant differences in the distributions of the rs1056827 and rs1056836 genotypes between the 2 groups. Regarding rs1056827, carriers of the T allele had a significantly higher risk of laryngeal cancer than the G-allele carriers (OR=1.4339, 95% CI: 1.1268-1.8247; P=0.0034). The difference was still statistically significant after adjusting for factors such as age, sex, smoking, and drinking (adjusted OR=1.743, 95% CI: 1.124-3.743, P<0.001). However, regarding rs1056836, the G allele carriers had a significantly lower risk of laryngeal cancer than the C allele carriers (OR=0.5557, 95% CI: 0.3787-0.8154; P=0.0027). The difference was statistically significant even after adjusting for factors such as age, sex, smoking, and drinking (adjusted OR=0.5641, 95% CI: 0.3212-0.8121, P=0.001). Subjects who carry the C-T-C haplotype have a significantly increased incidence of laryngeal cancer. We also found that CYP1B1 rs1056827 polymorphism had synergistic effects with smoking or alcohol consumption regarding the risk of laryngeal cancer.CYP1B1 gene polymorphism is closely related to the onset of laryngeal cancer. There is a mutually synergistic effect between smoking, alcohol consumption, and CYP1B1 gene polymorphisms regarding laryngeal cancer.
