Project description:BackgroundThe Fas rs180082 polymorphism has been reported to be associated with cervical cancer susceptibility, yet the results of these previous results have been inconsistent or controversial. The objective of this study was to explore whether the Fas rs180082 polymorphism confers susceptibility to cervical cancer.MethodsThe relevant studies were identified through a search of PubMed, Excerpta Medica Database (Embase), Elsevier Science Direct and Chinese Biomedical Literature Database (CBM) until July 2012. The association between the Fas rs180082 polymorphism and cervical cancer risk was assessed by odds ratios (ORs) together with their 95% confidence intervals (CIs).ResultsA total of 7 case-control studies were eventually identified. We found no association between Fas rs180082 polymorphism and cervical cancer susceptibility in overall population (G versus A: OR = 1.03, 95% CI = 0.99-1.07, P = 0.197; AG + GG versus AA: OR = 1.04, 95% CI = 0.98-1.09, P = 0.176; GG versus AA + AG: OR = 1.04, 95% CI = 0.84-1.31, P = 0.701). In subgroup analysis, similar results were found in Asian (G versus A: OR = 1.06, 95% CI = 0.97-1.15, P = 0.195; AG + GG versus AA: OR = 1.08, 95% CI = 0.98-1.19, P = 0.176; GG versus AA + AG: OR = 0.97, 95% CI = 0.51-1.84, P = 0.935) and African (G versus A: OR = 1.01, 95% CI = 0.97-1.15, P = 0.195; AG + GG versus AA: OR = 0.99, 95% CI = 0.91-1.07, P = 0.739; GG versus AA + AG: OR = 1.09, 95% CI = 0.94-1.25, P = 0.745).ConclusionThis meta-analysis has shown that there is a lack of association of the Fas rs180082 polymorphisms with cervical cancer susceptibility. However, larger scale primary studies with the consideration of gene-gene and gene-environment interactions are still required to further evaluate the interaction of Fas rs180082 polymorphism with cervical cancer susceptibility.

Project description:BackgroundIt was reported that Fas (rs1800682, rs2234767) and FasL (rs5030772, rs763110) gene polymorphism might be related to the risk of musculoskeletal degenerative diseases (MSDD), such as osteoarthritis (OA), intervertebral disc degeneration (IVDD) and rheumatoid arthritis (RA). However, data from different studies was inconsistent. Here we aim to elaborately summarize and explore the association between the Fas (rs1800682, rs2234767) and FasL (rs5030772, rs763110) and MSDD.MethodsLiteratures were selected from PubMed, Web of Science, Embase, Scopus and Medline in English and VIP, SinoMed, Wanfang and the China National Knowledge Infrastructure (CNKI) in Chinese up to August 21, 2017. All the researches included are case-control studies about human. We calculated the pooled odds ratios (ORs) with 95% confidence intervals (95% CI) to evaluate the strengths of the associations of Fas (rs1800682, rs2234767) and FasL (rs5030772, rs763110) polymorphisms with MSDD risk.ResultsEleven eligible studies for rs1800682 with 1930 cases and 1720 controls, 6 eligible studies for rs2234767 with 1794 cases and 1909 controls, 3 eligible studies for rs5030772 with 367 cases and 313 controls and 8 eligible studies for rs763110 with 2010 cases and 2105 controls were included in this analysis. The results showed that the G allele of Fas (rs1800682) is associated with an increased risk of IVDD in homozygote and recessive models. The G allele of Fas (rs2234767) is linked to a decreased risk of RA but an enhanced risk of OA in allele and recessive models. In addition, the T allele of FasL (rs763110) is correlated with a reduced risk of IVDD in all of models. However, no relationship was found between FasL (rs5030772) and these three types of MSDD in any models.ConclusionsFas (rs1800682) and FasL (rs763110) polymorphism were associated with the risk of IVDD and Fas (rs2234767) was correlated to the susceptibility of OA and RA. Fas (rs1800682) and Fas (rs2234767) are more likely to be associated with MSDD for Chinese people. FasL (rs763110) is related to the progression of MSDD for both Caucasoid and Chinese race groups. But FasL (rs5030772) might not be associated with any types of MSDD or any race groups statistically.

Project description:BackgroundNumber of studies have been performed to evaluate the relationship between the cytotoxic T-lymphocyte associated antigen-4 (CTLA-4) gene variant rs5742909 polymorphism and cervical cancer risk, but the sample size was small and the results were conflicting. This meta-analysis was conducted to comprehensively evaluate the overall association.MethodsPubMed, Web of Science, Embase, China Biology Medical Literature database, China National Knowledge Infrastructure, WanFang, and Weipu databases were searched before July 31, 2018. The strength of associations was assessed using odds ratios (ORs) and 95% confidence intervals (CIs). All of the statistical analyses were conducted using Review Manager 5.3 and Stata 14.0.ResultsEleven studies involved 3899 cases and 4608 controls. Overall, significant association was observed between the CTLA-4 gene variant rs5742909 polymorphism and cervical cancer (T vs C: OR = 1.40, 95% CI = 1.12-1.76; TT vs CC: OR = 2.22, 95% CI = 1.13-4.37; TT vs CT+CC: OR = 1.96, 95% CI = 1.03-3.74; TT+CT vs CC: OR = 1.47, 95% CI = 1.14-1.90). In subgroup analysis by ethnic group, a statistically significant association was observed in Asians (T vs C: OR = 1.56, 95% CI = 1.22-1.99), but not in Caucasians (T vs C: OR = 1.19, 95% CI = 0.87-1.62). The sensitivity analysis confirmed the reliability and stability of the meta-analysis.Conclusionour meta-analysis supports that the CTLA-4 gene variant rs5742909 polymorphism might contribute to individual susceptibility to cervical cancer in Asians.

Project description:The association between the risk of allograft rejection after organ transplantation and FAS gene polymorphism has been evaluated previously. However, inconsistent results have been reported. Hence, we conducted the most up-to-date meta-analysis to evaluate this association. All eligible studies reporting the association between FAS-670A＞G polymorphism and the risk of allograft rejection published up to December 2019 were extracted using a comprehensive systematic database search in the Web of Science, Scopus, and PubMed. The pooled odds ratios (OR) and corresponding 95% confidence intervals (CI) were calculated to determine the association strength. This meta-analysis included six case-control studies with 277 patients who experienced allograft rejection and 1,001 patients who did not experience allograft rejection (controls) after organ transplantation. The overall results showed no significant association between FAS-670A＞G polymorphism and the risk of allograft rejection in five genetic models (dominant model: OR=0.81, 95% CI=0.58‒1.12; recessive model: OR=0.10, 95% CI=0.80‒1.53; allelic model: OR=0.96, 95% CI=0.79‒1.18; GG vs. AA: OR=0.92, 95% CI=0.62‒1.36; and AG vs. AA: OR=0.75, 95% CI=0.52‒1.08). Moreover, subgroup analysis according to ethnicity and age did not reveal statistically significant results. Our findings suggest that FAS-670A＞G polymorphism is not associated with the risk of allograft rejection after organ transplantation.

Project description:BackgroundCD95 rs2234767 polymorphism in the promotor region of CD95 gene has been implicated in several studies of cervical cancer. However, the results have not been conclusively established.ObjectiveThe main aim of this study was to deal with the controversy with respect to the correlation between CD95 rs2234767 polymorphism and risk of cervical cancer through a meta-analysis.MethodsAssociation studies that pertain to CD95 rs2234767 polymorphism and risk of cervical cancer were identified up to May 26, 2014. ORs and 95% CIs were calculated assuming AA versus GG, AA + AG versus GG, AA versus AG + GG, A versus G and AG versus GG genetic models.ResultsA total of 5 case-control studies were included in this meta-analysis. Overall, no significant effect modification of cervical cancer risk was revealed either at the genotypic or the allelic level for CD95 rs2234767 polymorphism. This null association persisted in the stratified analysis of Asian population.ConclusionsThese findings revealed that CD95 rs2234767 polymorphism may not act as a causative agent of cervical cancer. Further evidence is needed to confirm our findings.

Project description:To evaluate the association between the SPO11 gene C631T polymorphism and the risk of male infertility. We conducted a search on PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure (CNKI), China biology medical literature database (CBM), VIP, and Chinese literature database (Wan Fang) on 31 March 2016. Odds ratio (OR) and 95% confidence interval (95%CI) were used to assess the strength of associations. A total of five studies including 542 cases and 510 controls were involved in this meta-analysis. The pooled results indicated that the SPO11 gene C631T polymorphism was significantly associated with increased risk of male infertility (TT?+?CT vs. CC: OR?=?4.14, 95%CI?=?2.48-6.89; CT vs. CC: OR?=?4.34, 95%CI?=?2.56-7.34; T vs. C: OR?=?4.35, 95%CI?=?2.58-7.34). Subgroup analysis of different countries proved the relationship between SPO11 gene C631T polymorphism and male infertility risk in Chinese, but not in Iranian peoples. In conclusion, this study suggested that SPO11 gene C631T polymorphism may contribute as a genetic factor susceptible to cause male infertility. Furthermore, more large sample and representative population-based cases and well-matched controls are needed to validate our results.

Project description:The polymorphisms in Fas/FasL system were proposed to be associated with susceptibility to leukemia, but recent studies reported controversial findings. Hence, we performed a meta-analysis to assess the association between Fas gene polymorphisms and susceptibility to leukemia. We carried out a literature search in PubMed, Embase, Web of Science and CNKI databases for studies on the associations between Fas/FasL gene polymorphisms and susceptibility to leukemia. The associations were assessed by odds ratio (OR) together with its 95% confidence intervals (CIs). 7 literatures and 14 studies with a total of 8787 subjects were eventually included into our meta-analysis. Overall, there was no association between Fas/FasL polymorphisms and susceptibility to leukemia. In subgroup analysis by ethnicity, there was also no association between Fas/FasL polymorphisms and susceptibility to leukemia in Asians and Caucasians. In addition, there was also a significant association between Fas-1377G/A polymorphism and susceptibility to leukemia in ALL patients, the A allele seemed to be a protective factor in ALL risk. In summary, more studies with large sample size are needed to provide further evidence for association between Fas/FasL polymorphisms and susceptibility to leukemia.

Project description:BackgroundTumor necrosis factor- alpha (TNF-α) is an inflammatory cytokine which may play important role on the immune response may control the progression of cervical lesions. There is a possible association between TNF-α rs1800629 G/A polymorphism and cervical lesions, but previous studies report conflicting results. We performed a meta-analysis to comprehensively assess the association between TNF-α rs1800629 polymorphism and cervical lesions risk.MethodsLiterature searches of Pubmed, Embase, Web of Science, and Wanfang databases were performed for all publications on the association between TNF-α rs1800629 polymorphism and cervical lesions through December 15, 2012. The pooled odds ratios (ORs) with their 95% confidence interval (95%CIs) were calculated to assess the strength of the association.ResultsTwenty individual case-control studies from 19 publications with a total of 4,146 cases and 4,731 controls were finally included into the meta-analysis. Overall, TNF-α rs1800629 polymorphism was significantly associated with increased risk of cervical lesions under two main genetic comparison models (For A versus G: OR 1.22, 95%CI 1.04-1.44, P = 0.017; for AA versus GG: OR 1.32, 95%CI 1.02-1.71, P = 0.034). Subgroup analysis by ethnicity further showed that there was a significant association between TNF-α rs1800629 polymorphism and increased risk of cervical lesions in Caucasians but not in Asians. Subgroup analysis by the types of cervical lesions showed that there was a significant association between TNF-α rs1800629 polymorphism and increased risk of cervical cancer (For A versus G: OR 1.24, 95%CI 1.05-1.47, P = 0.011; for AA versus GG: OR 1.31, 95%CI 1.01-1.70, P = 0.043; for AA/GA versus GG: OR 1.25, 95%CI 1.01-1.54, P = 0.039).ConclusionThe meta-analysis suggests that TNF-α rs1800629 polymorphism is associated with increased risk of cervical lesions, especially in Caucasians.

Project description:BackgroundSome studies have evaluated the association between the Ubiquilin 1 (UBQLN1) gene UBQ-8i polymorphism and Alzheimer's disease (AD). However, the results remain uncertain. We carried out a meta-analysis to derive a more comprehensive estimation of this association.Material/methodsCase-control studies were identified by searching databases of PubMed, EMBASE, Web of Science, CNKI, CBM, Wanfang, and VIP. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of the association.ResultsThe UBQ-8i polymorphism was significantly associated with an increased AD risk (OR=1.15; 95%CI 1.05-1.25; P=0.002). The combination of adjusted ORs also found UBQ-8i polymorphism was significantly associated with AD risk (OR=1.15; 95%CI 1.02-1.30; P=0.02). When stratified by APOE ε4 status, both APOE ε4 carriers and APOE non-ε4 carriers with UBQ-8i polymorphism had significantly increased AD risk (OR=1.28; 95%CI 1.05-1.56; P=0.01 and OR=1.25; 95%CI 1.04-1.50; P=0.02). In the subgroup analysis according to age, UBQ-8i polymorphism was significantly associated with LOAD risk (OR=1.17; 95%CI 1.05-1.31; P=0.005), but not with EOAD risk (OR=1.12; 95%CI 0.95-1.31; P=0.17).ConclusionsThese results suggest that the UBQ-8i polymorphism is associated with AD risk.

Project description:BACKGROUND:Hypoxia-inducible factor-1 alpha (HIF-1?) P582S polymorphism has been reported to increase transactivation capacity of HIF-1?, which is prone to tumorigenesis. Several published case-control studies on the association between P582S polymorphism and cervical cancer have shown mixed results. In this study, we chose to perform a meta-analysis to assess the association. METHODOLOGY/PRINCIPAL FINDINGS:We conducted a meta-analysis consisting of four studies with a total of 846 cases and 991 controls. All data were collected and overall comparison was performed among all subjects. Using the fixed effects model, the homozygous and the recessive models showed a significant increase in the risk of cervical cancer (the pooled OR=6.32, 95% CI=2.28-17.55, Phet=0.348; the pooled OR=5.86, 95% CI=2.13-16.11, Phet=0.394 respectively). Publication bias was not significantly indicated in this analysis. CONCLUSIONS:This meta-analysis demonstrates that HIF-1? P582S polymorphism may be associated with the risk of cervical cancer.
