The association between rs16917496 T/C polymorphism of SET8 gene and cancer risk in Asian populations: a meta-analysis.

ABSTRACT: Epidemiological studies have demonstrated close associations between SET8 rs16917496 T/C polymorphism and cancer risk, but the results of published studies were not consistent. We therefore performed this meta-analysis to explore the associations between rs16917496 T/C polymorphism and cancer risk. Five online databases were searched. Odds ratios (ORs) with a 95% confidence interval (CI) were calculated to assess the association between rs16917496 T/C polymorphism and cancer risk. In addition, heterogeneity, accumulative, sensitivity analysis, and publication bias were conducted to check the statistical power. Overall, 13 publications involving 5878 subjects were identified according to included criteria. No significant cancer risk was observed in genetic model of SET8 rs16917496 T/C polymorphism in Asian populations (C vs. T: OR = 1.04, 95%CI = 0.88-1.23, P = 0.63%; TC vs. TT: OR = 1.17, 95%CI = 0.96-1.24, P = 0.11%; CC vs. TT: OR = 0.90, 95%CI = 0.60-1.37, P = 0.63; TC+CC vs. TT: OR = 1.11, 95%CI = 0.90-1.38, P = 0.33; CC vs. TT+TC: OR = 0.92, 95%CI = 0.65-1.30, P = 0.63). Furthermore, similar associations were found in the subgroup analysis of race diversity, control design, genotyping methods, and different cancer types. In summary, our meta-analysis indicated that the SET8 rs16917496 T/C polymorphism may not play a critical role in cancer development in Asian populations.

Project description:BackgroundPhosphatase and tensin homolog (PTEN) is a well established tumor suppressor gene. Recently, increasing studies investigated the association between PTEN IVS4 polymorphism (rs3830675) and risk of various types of cancer. However, the results from the individual studies were controversial. The aim of this meta-analysis was to elucidate whether PTEN IVS4 polymorphism was associated with cancer risk.MethodsDatabases including PubMed, Web of knowledge and Chinese National Knowledge Infrastructure (CNKI) were systematically searched to identify potentially eligible literatures. Odds ratios (OR) and their 95% confidence interval (CI) were used to assess the strength of association between PTEN IVS4 polymorphism and cancer risk.ResultsA total of seven case-control studies were finally included in this meta-analysis. The pooled analysis suggested that individuals with PTEN IVS4 (-/-) genotype were significantly associated with increased risk of cancer (OR = 1.45, 95% CI = 1.19-1.76, P<0.001) and subgroup of digestive tract cancer (OR = 1.67, 95% CI = 1.28-2.18, P<0.001) compared with (+/+) genotype. The allele analysis revealed that (-) allele was significantly associated with increased risk of cancer (OR = 1.30, 95% CI = 1.12-1.50, P = 0.001) and subgroup of digestive tract cancer (OR = 1.42, 95% CI = 1.16-1.74, P = 0.001) compared with (+) allele. No significant association was observed between PTEN IVS4 (+/-) genotype and risk of cancer.ConclusionPTEN IVS4 (-/-) genotype was significantly associated with increased risk of cancer especially for digestive tract cancer compared with (+/+) genotype. The (-) allele of PTEN IVS4 (rs3830675) polymorphism was significantly associated with increased risk of cancer especially for digestive tract cancer compared with (+) allele. The recessive effect model and dominant effect model also demonstrated significant association between PTEN IVS4 (rs3830675) polymorphism and increased cancer risk especially for digestive tract cancer. Further large-scale and well-designed studies regarding different ethnicities are still required to confirm the results of our meta-analysis.

Project description:Background and objectiveThe gene betaine-homocysteine methyltransferase (BHMT) has drawn much attention during the past decades. An increasing number of clinical and genetic investigations have supposed that BHMT rs3733890 polymorphism might be associated with risk of breast cancer and ovarian cancer. As no consistent conclusion has been achieved, we conducted an up-to-date summary of BHMT rs3733890 polymorphism and cancer risk through a meta-analysis.Materials and methodsThe articles were collected from PubMed, Google Scholar, and CNKI (Chinese) databases up to December 2015. Then, the correlations were determined by reading the titles and abstracts and by further reading the full text to filter the unqualified articles. Odds ratio (OR) and the corresponding 95% confidence intervals (CI) were used to assess the results.ResultsAmong 187 articles collected in the analysis, seven studies with a total of 2,832 cases and 3,958 controls were included for evaluation of the association between BHMT rs3733890 polymorphism and susceptibility of cancer risk. The heterogeneity test showed no significant differences. Furthermore, we found that BHMT -742G>A polymorphism in case and control groups showed no statistically significant association with susceptibility in various cancer types except for uterine cervical cancer (A vs G: OR =0.641, 95% CI =0.445-0.923, P=0.017; AA+AG vs GG: OR =0.579, 95% CI =0.362-0.924, P=0.022). In addition, no statistically significant association was uncovered when stratification analyses were conducted by ethnicity and genotyping methods.ConclusionOur results have shown no obvious evidence that rs3733890 polymorphism in BHMT gene affected the susceptibility of head and neck squamous cell carcinoma, breast cancer, ovarian cancer, colorectal adenoma, and liver cancer. In contrast, we found the protective role of BHMT -742G>A polymorphism in uterine cervical cancer incidence. Future well-designed studies comprising larger sample size are warranted to verify our findings.
