Renal cell carcinoma risk is associated with the interactions of APOE, VHL and MTHFR gene polymorphisms.

ABSTRACT: The study was designed to explore the association of renal cell carcinoma (RCC) with VHL (rs779805), MTHFR (rs1801133) and APOE (rs8106822 and rs405509) polymorphisms, investigate the interactions among the single nucleotide polymorphisms (SNPs), and explore roles of the interactions in the pathogenesis of RCC in Chinese Han population.81 RCC patients and 80 healthy controls were included in the study. Polymerase chain reaction (PCR) and direct sequencing methods were used in the analysis on the genotypes of APOE, VHL and MTHFR gene polymorphisms. Multifactor dimensionality reduction (MDR) method was adopted to conduct gene-gene interaction analysis. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were utilized to evaluate the correlation between gene-gene interactions and RCC risk.Significant correlations were found between RCC risk and 3 SNPs (rs8106822, rs779805 and rs1801133). Genotype AA and allele A of APOE rs8106822 were significantly associated with RCC susceptibility (OR=2.65, 95% CI=1.05-6.69). Meanwhile, we found that the frequencies of genotype GG and allele G were much higher in case group, compared with controls (P<0.05 for both) and they appeared to be risk factors for RCC (OR=2.90, 95% CI=1.22-6.87; OR=1.78, 95% CI=1.14-2.27). While, allele T of MTHFR rs1801133 could decrease the risk of RCC (OR=0.62, 95% CI=0.40-0.97). MDR analysis showed that gene-gene interactions among APOE, VHL and MTHFR SNPs were closely related with RCC susceptibility.APOE, VHL and MTHFR gene polymorphisms were related to the risk of RCC. The interactions among APOE, VHL and MTHFR genes could increase the risk of RCC.

Project description:ObjectiveTo analyze the relationship between plasma metal elements, ApoE gene polymorphisms and the interaction between the two and impaired cognitive function in elderly population.MethodA stratified sample was drawn according to the age of the study population, and 911 subjects were included. Baseline information and health indicators were obtained, and cognitive function status was assessed by health examination, a general questionnaire and Mini-Mental Status Examination. Plasma metal elements were measured, and SNP typing was performed. Binary logistic regression was used to analyze the factors influencing cognitive function status and the association between the SNP genetic pattern of the ApoE gene and cognitive function.ResultsThe differences in gene frequencies and genotype frequencies of the ApoE rs7412 and rs7259620 genotype frequencies were statistically different between the cognitive impairment group and the control group (P < 0.05). statistically differences were found for the codominant model in rs7412-TT compared with the CC genotype (OR = 3.112 (1.159-8.359), P = 0.024) and rs7259620-AA compared with the GG genotype (OR = 1.588 (1.007-2.504), P = 0.047). Statistically differences were found in the recessive models rs7412-TT compared with (CC + CT) (OR = 2.979 (1.112-7.978), P = 0.030), rs7259620-AA compared with (GG + GA), and rs405509-GG compared with (TT + TG) (OR = 1.548(1.022-2.344), P = 0.039) all of which increased the risk of developing cognitive impairment. The differences in plasma Fe, Cu, and Rb concentrations between the case and control groups were significant (P < 0.05). The regression results showed that the plasma Cd concentrations in the Q1 range was a protective factor for cognitive function compared with Q4 (0.510 (0.291-0.892), P = 0.018). Furthermore, there was a multiplicative interaction between the codominant and recessive models for the Q2 concentrations of Cd and the rs7259620 loci, and the difference was significant, indicating increased risk of developing cognitive impairment (codominant model OR = 3.577 (1.496-8.555), P = 0.004, recessive model OR = 3.505 (1.479-8.307), P = 0.004). There was also a multiplicative interaction between Cd and the recessive model at the rs405509 loci, and the difference was significant, indicating increased risk of developing cognitive impairment (OR = 3.169 (1.400-7.175), P = 0.006).ConclusionThe ApoE rs7412, rs7259620 and rs405509 loci were associated with cognitive impairment in the elderly population, and there was an interaction between plasma metalloid Cd and the rs7259620 and rs405509 loci that increased the risk of cognitive impairment in the elderly population.
