Several studies inspected the relationship between caspase-3 (CASP3) polymorphisms and the risk of several human cancers, but the findings remain controversial. We conducted a meta-analysis aiming to inspect the association between CASP3 rs1049216 T>C, rs12108497 C>T, rs4647603 G>A, rs4647602 C>A, rs6948 T>G, rs2705897 A>C, and rs113420705 G>A polymorphisms and cancer risk. Eligible studies were recognized by searching the Web of Science, PubMed, Scopus, and Google Scholar databases. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to quantitatively evaluate the association between each polymorphism of CASP3 and cancer risk. The rs4647603 variant significantly increased the risk of cancer in an overdominant (OR, 1.44; 95% CI, 1.03-2.01; P = 0.03; AG vs AA+GG) inheritance model. Regarding the rs4647602 variant, the findings revealed that this variant was associated with protection against cancer in homozygous codominant (OR, 0.67; 95% CI, 0.56-0.80; P < 0.00001; AA vs CC), dominant (OR, 0.84; 95% CI, 0.73-0.96; P = 0.009; AC+AA vs CC), recessive (OR, 0.70; 95% CI, 0.61-0.79; P < 0.00001; AA vs AC+CC), and allele (OR, 0.81; 95% CI, 0.75-0.88; P = 0.00001; A vs C) models. The findings suggested that the rs2705897 variant significantly decreased the risk of cancer in heterozygous codominant (OR, 0.80; 95% CI, 0.67-0.94; P = 0.009; AC vs AA), dominant (OR, 0.81; 95% CI, 0.69-0.95; P = 0.009; AC+CC vs AA), overdominant (OR, 0.80; 95% CI, 0.68-0.95; P = 0.01; AC vs CC+AA), and allele (OR, 0.85; 95% CI, 0.74-0.97; P = 0.02; C vs A) models. The results did not support an association between CASP3 rs1049216 and rs6948 polymorphisms and cancer risk. In summary, the findings of this meta-analysis support an association between CASP3 polymorphisms and cancer risk. Larger and well-designed studies are desired to evaluate these associations in detail. 相似文献

Flap endonuclease 1 (FEN1) has emerged as an important enzyme in the maintenance of genomic instability and preventing carcinogenesis. The relationship between FEN1 −69G>A (rs174538)+4150G>T (rs4246215) polymorphisms and cancer susceptibility has been reported; however, results were inconclusive. In the present study, a meta-analysis of data from eligible reports was carried out to summarize the possible relationship between FEN1 polymorphisms and cancer risk. A total of 11 articles, including 20 studies with 7366 cases and 9028 controls and 18 studies with 6649 cases and 8325 controls for FEN1 rs174538 and FEN1 rs4246215 polymorphisms, respectively, were recruited for meta-analysis. Overall, meta-analyses showed that FEN1 rs174538 and rs4246215 polymorphisms are significantly associated with the decreased risk of cancer. The stratified analysis proposed that both variants were associated with protection against gastrointestinal cancer, breast cancer, hepatocellular cancer, esophageal cancer, gastric cancer, colorectal cancer, and lung cancer. In conclusion, this meta-analysis revealed an association between FEN1 polymorphisms and cancer risk. Additional studies in a larger study population that include subjects from a variety of ethnicities are warranted to further verify our findings. 相似文献

IL-27 plays an important role in anti-cancer activity. The -964A/G polymorphism in IL-27 gene has been implicated in susceptibility to cancer, but the results were conflicting. The aim of this study was to assess the association between this polymorphism and cancer risk. Pubmed and Wanfang database were searched for all publications concerning IL-27 -964A/G polymorphism and cancer risk. Odds ratio (OR) and 95% confidence interval (CI) were used to assess the strength of association. Statistical analysis was performed using Stata 11.0 software. A total of eight case–control studies including 2044 cancer cases and 2197 controls were identified. Overall, significant association between IL-27 -964A/G polymorphism and cancer risk was observed (GG versus AA: OR?=?1.26, 95% CI?=?1.03–1.52; GG versus AG?+?AA: OR?=?1.20, 95% CI?=?1.00–1.44). In subgroup analysis based on cancer type, significant association was found in colorectal cancer (GG versus AA: OR?=?1.55, 95% CI?=?1.07–2.27; AG versus AA: OR?=?1.31, 95% CI?=?1.02–1.67). The current meta-analysis suggests that IL-27 -964A/G polymorphism might enhance cancer risk. However, large-scale and well-designed studies are still needed to confirm the result of our meta-analysis. The association of IL-27 polymorphism with colorectal cancer may provide insight for future therapies. 相似文献

Background: Interleukin-27 (IL-27) has been recognized as a pleiotropic cytokine with both pro- and anti-inflammatory properties.Patients and methods: A case-control study was conducted to investigate the possible associations of IL-27 gene polymorphisms with susceptibility to cervical cancer and clinical outcome.Results: Our results suggested that the IL-27 2905T/G was significantly associated with a decreased risk of cervical cancer. Further analysis showed IL-27 2905T/G genotypes were associated with advanced tumor stages of cervical cancer patients. More interestingly, the IL-27 2905T/G genotypes were statistically significantly associated with the survival in cervical cancer patients.Conclusion: Our results showed that the IL-27 2905T/G genotypes were associated with decreased the susceptibility and development of cervical cancer in Chinese Han population. 相似文献

The mitochondrial manganese superoxide dismutase (MnSOD) enzyme protects lungs against oxidative stress by neutralizing the free radical superoxide produced in the respiratory function. This has relevance to asthma. Therefore, it is of interest to describe the potential effect of MnSOD Ala16Val genetic polymorphism to asthma risk. Known data in this context is inconclusive in nature. The possible link between MnSOD Ala16Val polymorphism and asthma is explored using sequence meta-analysis. Data from the pooled analysis of MnSOD Ala16Val polymorphism using five genetic models i.e., allelic (Val vs. Ala: p=0.846; OR=1.033, 95% CI=0.742 to 1.440) is discussed. Homozygous (Val Val vs. Ala Ala: p=0.517; OR=1.307, 95% CI=0.582 to 2.932) and heterozygous (Val Ala vs. Ala Ala: p=0.307; OR=1.138, 95% CI=0.888 to 1.459) data using the described models are documented. Data from the dominant model (Val Val + Val Ala vs. Ala Ala: p=0.301; OR=1.289, 95% CI=0.797 to 2.085) and the recessive model (Val Val vs. Val Ala + Ala Ala: p=0.761; OR=0.924, 95% CI=0.555 to 1.538) analyses for several ethnic subgroups in this context is reported. 相似文献

The findings regarding the relation of transporter associated with antigen processing (TAP) to cancer risk have been inconsistent. The aim of this study was to comprehensively evaluate the association between TAP2 rs241447 polymorphism and cancer susceptibility. A meta-analysis of nine investigations with 2800 cases and 1620 controls was conducted to gain a better understanding of the effect of TAP2 rs241447 polymorphism on cancer risk. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to evaluate the strength of the correlation between TAP2 gene polymorphism and cancer susceptibility. The pooled results from TAP2 rs241447 polymorphism showed a decreased risk of cancer in two dominant genetic models (GG + AG vs AA: OR = 0.86, 95% CI, 0.75-0.99; AG vs AA: OR = 0.85, 95% CI, 0.73-0.99). From the subgroup analysis, decreased cancer susceptibility was found in Caucasians (GG + AG vs AA: OR = 0.82, 95% CI, 0.68-0.99), especially among the subgroup of cervical carcinoma (GG + AG vs AA: OR = 0.82, 95% CI, 0.69-0.96; AG vs AA: OR = 0.83, 95% CI, 0.70-0.99). Overall, the results suggest that TAP2 rs241447 polymorphism contributes to decreased cancer susceptibility. 相似文献

AbstractRelationship between vitamin D receptor (VDR) gene polymorphism and the risk of lung cancer from the published reports are still conflicting. This study was conducted to evaluate the relationship between VDR TaqI (rs731236), BsmI (rs1544410) and ApaI (rs7975232) gene polymorphism and the risk of lung cancer using meta-analysis method. The association studies were identified from PubMed and Cochrane Library on 1 December 2013, and eligible investigations were included and synthesized using meta-analysis method. Six reports were recruited into this meta-analysis for the association of VDR gene polymorphism with lung cancer susceptibility. In the meta-analysis for ApaI gene polymorphism, AA genotype was associated with the risk of lung cancer in Asians. In the meta-analysis for BsmI gene polymorphism, B allele, BB genotype and bb genotype were associated with lung cancer in Asians, and B allele bb genotype were associated with lung cancer risk in overall populations; furthermore, bb genotype was associated with lung cancer risk in Caucasians. In the meta-analysis for TaqI gene polymorphism, t allele and TT genotype were associated with lung cancer in overall populations and in Caucasians. In conclusion, B allele bb genotype t allele and TT genotype were associated with lung cancer risk in overall populations. AA genotype, B allele, BB genotype and bb genotype were associated with the risk of lung cancer in Asians. Furthermore, bb genotype t allele and TT genotype was associated with lung cancer risk in Caucasians. However, more studies should be conducted to confirm it. 相似文献

AbstractObjective: To explore whether the functional chemokine receptor 5 delta32 (CCR5-Δ32) polymorphism is associated with susceptibility to cancer. Methods: A meta-analysis was conducted on the association between the CCR5-Δ32 polymorphism and cancer using (i) allele contrast and (ii) the dominant model. Results: Thirteen articles, including 16 comparative studies on a total of 3087 patients and 3735 controls, were included in the meta-analysis. These studies encompassed breast cancer (n?=?3), bladder cancer (n?=?3), cervical cancer (n?=?2), pancreatic cancer (n?=?2), prostate cancer (n?=?2), head and neck cancer (n?=?2), lymphoma (n?=?1), gallbladder cancer (n?=?1), skin cancer (n?=?1) and mixed cancer (n?=?1). The meta-analysis revealed an association between cancer and the CCR5-Δ32 allele (OR?=?1.368, 95% CI?=?1.064–1.758, p?=?0.014), and stratification by ethnicity showed an association between the CCR5-Δ32 allele and cancer in Indians (OR?=?2.480, 95% CI?=?1.247–4.932, p?=?0.010). The meta-analysis also revealed an association between breast cancer and the CCR5-Δ32 allele (OR?=?1.689, 95% CI?=?1.012–2.821, p?=?0.045). However, allele contrast and the dominant model failed to reveal an association between the CCR5-Δ32 polymorphism and bladder cancer, cervical cancer, pancreatic cancer, prostate cancer, and head and neck cancer. Conclusions: This meta-analysis demonstrates that the CCR5-Δ32 polymorphism is associated with susceptibility to cancer in Indians and is associated with breast cancer. 相似文献

Background
Previous studies have focused on the association of miR-34 family members with carcinogenesis of many cancers, including hepatocellular carcinoma (HCC). It has been suggested that miR-34b/c polymorphism (rs4938723) is associated with susceptibility to HCC. In the present study, we performed a meta-analysis to systematically summarize the possible association between rs4938723 and the risk for HCC.Methodology/Principal Findings
We conducted a search of case-control studies on the associations of rs4938723 with susceptibility to HCC in PubMed, EMBASE, ISI Web of Science, Cochrane Central Register of Controlled Trials, ScienceDirect, Wiley Online Library, Wangfang database in China, and Chinese National Knowledge Infrastructure databases. Data from eligible studies were extracted for meta-analysis. HCC risk associated with rs4938723 was estimated by pooled odds ratios (ORs) and 95% confidence intervals (95% CIs). 3 studies on rs4938723 were included in our meta-analysis. Our results showed that neither allele frequency nor genotype distribution of the rs4938723 was associated with risk for HCC in all genetic models.Conclusions/Significance
This meta-analysis suggests that rs4938723 is not associated with the risk of HCC. Well-designed studies with larger sample size and more ethnic groups are required to further validate the results. 相似文献15.
Background: There is accumulating evidence of aberrant expression of miR-143 and miR-145 and their target gene KRAS in colorectal cancer (CRC). We hypothesize that single nucleotide polymorphisms (SNPs) within or near mRNA–microRNA (miRNA) binding sites may affect miRNA/target gene interaction, resulting in differential mRNA/protein expression and promoting the development and progression of CRC. Methods: We conducted a case–control study of 507 patients with CRC recruited from a tertiary hospital and 497 population-based controls to assess the association of genetic polymorphisms in miR-143/145 and the KRAS 3′ untranslated region (3′UTR) with susceptibility to CRC and patients’ survival. In addition, genetic variations of genomic regions located from 500 bp upstream to 500 bp downstream of the miR-143/miR-145 gene and the 3′UTR of KRAS were selected for analysis using the Haploview and HaploReg software. Results: Using publicly available expression profiling data, we found that miR-143/145 and KRAS expression were all reduced in rectal cancer tissue compared with adjacent non-neoplastic large intestinal mucosa. The rs74693964 C/T variant located 65 bp downstream of miR-145 genomic regions was observed to be associated with susceptibility to CRC (adjusted odds ratio (OR): 2.414, 95% CI: 1.385–4.206). Cumulative effects of miR-143 and miR-145 on CRC risk were observed (Ptrend=0.03). Patients having CRC carrying variant genotype TT of KRAS rs712 had poorer survival (log-rank P=0.044, adjusted hazard ratio (HR): 4.328, 95% CI: 1.236–15.147). Conclusions: Our results indicate that miRNA-related polymorphisms in miR-143/145 and KRAS are likely to be deleterious and represent potential biomarkers for susceptibility to CRC and patients’ survival. 相似文献

Published data on the rs2910164 in microRNA-146a (miR-146a) are shown to be associated with increased or decreased autoimmune diseases risk. To derive a more precise estimation of the relationship, we performed a meta-analysis to systematically summarize the possible. A meta-analysis including 11 studies with 3042 controls and 2197 cases was performed for genotypes CC (recessive effect), CC + CG (dominant effect) and C allele in fixed or random-effects models based on between-study heterogeneity. Overall, no significant association between miR-146a G/C rs2910164 polymorphism and autoimmune diseases risk was found in all genetic models when all studies were pooled into the meta-analysis. SLE (OR = 0.99, 95% CI: 0.90–1.10), RA (OR = 0.98, 95% CI: 0.85–1.14) did not yield statistical significance as for C allele pooled studies. In the subgroup analysis by ethnicity, still no significant association was detected in all genetic models. Our meta-analysis suggests that there is no association between miR-146a G/C rs2910164 polymorphism and the development of autoimmune diseases. 相似文献

Background: p53 tumor suppressor gene Arg72Pro polymorphism has been associated with gastric cancer. However, results were inconsistent. We performed this meta-analysis to estimate the association between p53 Arg72Pro polymorphism and gastric cancer.Methods: An electronic search of PubMed was conducted to select studies. Studies containing available genotype frequencies of Arg72Pro were chosen, and the association was assess by pooled odds ratio (ORs) with 95% confidence interval (CIs).Results: The meta-analysis suggested that the p53 Arg72Pro was associated with the gastric cancer risk (Additive model: OR = 1.149, 95% CI = 1.045–1.263, p = 0.004; Dominant model: OR = 1.18, 95% CI = 1.049–1.328, p = 0.006; Recessive model: OR = 1.202, 95% CI = 1.013–1.427, p = 0.035) in Asian subgroup.Conclusion: This meta-analysis suggests that p53 Arg72Pro polymorphism is associated with increased risk of gastric cancer in Asians. 相似文献
