Associations between the Genetic Polymorphisms of Osteopontin Promoter and Susceptibility to Cancer in Chinese Population: A Meta-Analysis.

ABSTRACT: Several studies have been conducted to examine the associations between osteopontin (OPN) promoter gene SPP1 polymorphisms with human cancers in Chinese population, but the results remain inconsistent. The aim of this meta-analysis is to clarify the associations between SPP1 polymorphisms and cancer susceptibility.All eligible case-control studies published up to March 2015 were identified by searching PubMed, Web of Science, Embase, and Cochrane Library without language restrictions. Pooled odds ratio (OR) and 95% confidence interval (95% CI) were calculated using fixed- or random-effect model.A total of 11 case-control studies were included; of those, there were eleven studies (3130 cases and 3828 controls) for -443T>C polymorphism, ten studies (3019 cases and 3615 controls) for -156G>GG polymorphism, eight studies (2258 cases and 2846 controls) for -66T>G polymorphism. Overall, no evidence indicated that the -443 T>C polymorphism was associated with cancer risk (OR = 0.93, 95%CI 0.62-1.38 for dominant model, OR = 1.06, 95%CI 0.73-1.55 for recessive model, OR = 0.88, 95%CI 0.62-1.26 for CT vs TT model, OR = 1.03, 95%CI 0.61-1.73 for CC vs TT model). While, a significantly increase risk was found for -156 G>GG polymorphism (OR = 1.22, 95%CI 1.10-1.35 for dominant model, OR = 1.25, 95%CI 1.10-1.41 for recessive model, OR = 1.18, 95%CI 1.06-1.32 for GGG vs GG model, OR = 1.35, 95%CI 1.09-1.68 for GGGG vs GG model). For -66T>G polymorphism, we found a decrease risk of cancer (OR = 0.84, 95% CI 0.71-0.98 for dominant model), but this result changed (OR = 0.93, 95% CI 0.77-1.12 for dominant model) when we excluded a study.This meta-analysis suggests that in Chinese population the -156G>GG polymorphism of SPP1 might be a risk factor for human cancers, while -443T>C mutation is not associated with cancer risk. For -66T>G polymorphism, it may be a protective factor for human cancers.

Project description:Study designMeta-analysis to collect all the relevant studies to further investigate whether or not the FAS ligand (FASL) and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) genetic polymorphisms are associated with susceptibility to intervertebral disc degeneration (IDD) in Chinese Han population.ObjectiveTo investigate whether or not the FASL and TRAIL genetic polymorphisms are associated with susceptibility to IDD in Chinese Han population.Summary of background dataFASL and TRAIL are both apoptotic gene. Several studies have assessed the associations of FASL and TRAIL gene with risk of IDD in Chinese Han population, but the results are inconsistent.MethodsWe systematically searched the PubMed, EMBASE, Medline, Scopus, Web of Science, CBM, and the Cochrane Library databases. Eligible studies assessing the polymorphisms in the FASL and TRAIL gene and risk of IDD were incorporated. The pooled odds ratio (OR) with its 95% confidence intervals (95% CI) was used.ResultsSix studies with a total of 1766 IDD cases and 1533 controls were finally included in the meta-analysis. Meta-analysis of FASL-844C/T (rs763110) polymorphism was statistically associated with decreased IDD risk under all genetic models (allele model: OR = 0.68, 95% CI 0.59-0.80, P = 0.000; homozygote model: OR = 0.35, 95% CI 0.25-0.53, P = 0.000; dominant model: OR = 0.38, 95% CI 0.25-0.58, P = 0.000; recessive model: OR = 0.69, 95% CI 0.58-0.84, P = 0.000). There was a significant association between TRAIL-1595C/T (rs1131580) polymorphism with increased IDD risk under each genetic model (allele model: OR = 1.77, 95% CI 1.47-2.13, P = 0.000; homozygote model: OR = 2.44, 95% CI 1.70-3.51, P = 0.000; dominant model: OR = 1.67, 95% CI 1.22-2.29, P = 0.002; recessive model: OR = 3.13, 95% CI 2.40-4.08, P = 0.000). In addition, the association between TRAIL-1525G/A (rs1131568) polymorphism and the susceptibility of IDD was statistically significant under all genetic models.ConclusionThe present meta-analysis demonstrated that FASL and TRAIL polymorphisms were significantly associated with susceptibility to IDD in Chinese Han population.Level of evidence1.

Project description:BackgroundThe tumour necrosis factor-α (TNF-α) gene plays an important role in the host immune response, which will influence the development and clearance of cancer. Polymorphism of the TNF-α promoter region is considered to influence its transcription and be a risk factor for tumorigenesis. In the current study, we evaluated the role of TNF-α promoter region polymorphisms in susceptibility to cervical intraepithelial neoplasia (CIN) and cervical cancer (CC).MethodsA total of 2732 subjects, including 1173 healthy controls, 579 patients with CIN and 980 patients with CC in a Chinese Han population, were selected for the current study. Five SNPs in the TNF-α promoter, rs1799964 (-1031 C>T), rs1800630 (-863 A>C), rs1799724 (-857 C>T), rs1800629 (-308 A>G) and rs361525 (-238 A>G), were selected and genotyped using TaqMan Assays. The association of these SNPs with CIN and cervical cancer was evaluated among healthy controls, CIN and CC patients.ResultsThe frequency distribution of rs1800629 and rs361525 alleles was significantly different between the CC group and the control group (P=0.009 and P=0.002). The rs1800629 A allele was found to be a protective factor for CC (OR=0.72; 95% CI=0.56-0.92). The rs361525 A allele was found to be a risk factor for CC (OR=1.69; 95% CI=1.21-2.38). After pathological subtyping of CC, the allele distribution of rs1800629 and rs361525 were both significantly different between the cervical squamous cell carcinoma and control groups (P=0.002 and P<0.001). The rs1800629 A allele was protective factor for cervical squamous cell carcinoma (OR=0.66; 95% CI=0.50-0.86). The rs361525 A allele was a risk factor for cervical squamous cell carcinoma (OR=1.87; 95% CI=1.32-2.65). Moreover, the genotypic frequency of rs361525 was significantly different between cervical cancer stage I and stage II (P=0.003).ConclusionThe rs1800629 and rs361525 in the TNF-α promoter are associated with susceptibility to CC in the Chinese Han population.
