Associations between FAS rs2234767 and FASL rs763110 polymorphisms and the risk of lung cancer: a meta-analysis of 39,736 subjects.

ABSTRACT: BACKGROUND:Previous studies have investigated the associations between the common polymorphisms in FAS/FASL genes and lung cancer risk; however, the results remain inconsistent and inconclusive. Hence, we performed a meta-analysis to reassess the relationships between FAS rs2234767 and FASL rs763110 polymorphisms and the risk of lung cancer. METHODS:Eligible studies retrieved by an electronic search were pooled to calculate the strength of the associations using the odds ratio (OR) and 95% confidence interval (95% CI). RESULTS:A total of 13 case-control studies involving 39,736 subjects (9,237 cases and 10,838 controls on FAS rs2234767 and 8,957 cases and 10,704 controls on FASL rs763110) were included in the meta-analysis. The results showed a significant association between FAS rs2234767 polymorphism and increased risk of lung cancer (A vs G: OR =1.07, 95% CI =1.01-1.13; AA vs GG: OR =1.23, 95% CI =1.06-1.43; AA vs GA + GG: OR =1.24, 95% CI =1.08-1.43). Similar association was also observed in Asian population (AA vs GA + GG: OR =1.30, 95% CI =1.01-1.67) and in the studies with large sample size (A vs G: OR =1.07, 95% CI =1.00-1.14; AA vs GG: OR =1.30, 95% CI =1.07-1.58). However, no significant association between FASL rs763110 polymorphism and lung cancer risk was found other than in the Asian population (CC vs TC + TT: OR =1.35, 95% CI =1.01-1.80). CONCLUSION:The meta-analysis indicated that FAS rs2234767 polymorphism was significantly associated with an increased risk of lung cancer and FASL rs763110 polymorphism may not contribute to susceptibility to lung cancer other than in Asian population.

Project description:BackgroundIn recent years, studies have demonstrated that polymorphisms in the promoters of Fas and FasL are significantly associated with breast cancer risk. However, the results of these studies were inconsistent. This case-control study was performed to explore the associations between Fas rs1800682 and FasL rs763110 polymorphisms and breast cancer.Materials and methodsA hospital-based case-control study of 560 Han Chinese females with breast cancer (583 controls) was conducted. The MassARRAY system was used to search for a possible association between the disease risk and the two single nucleotide polymorphisms, Fas rs1800682 and FasL rs763110. Statistical analyses were performed using SNPStats software to conduct Pearson's chi-square tests in five different genetic models. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated after adjustment to age and body mass index. PHASE v2.1 software was used to reconstruct all common haplotypes.ResultsA statistically significant association was found between Fas rs1800682 and increased breast cancer risk (AG vs AA: OR =1.37, 95% CI =1.06-1.78; AA+AG vs GG: OR =1.32, 95% CI =1.04-1.66), and also it was found that the FasL rs763110 polymorphism may decrease the risk. Stratified analyses demonstrated that the rs763110 polymorphism was associated with lower breast cancer risk among postmenopausal females (heterozygote model: OR =0.69, 95% CI =0.49-0.97; dominant model: OR =0.70, 95% CI =0.51-0.96). The T allele of rs763110 was also associated with a decreased risk of lymph node metastasis (allele model: OR =0.75, 95% CI =0.57-0.97) and an increased risk of the breast cancer being human epidermal growth factor receptor 2 positive (allele model: OR =1.37, 95% CI =1.03-1.18). Moreover, haplotype analysis showed that Ars1800682Trs763110 was associated to a statistically significant degree with lower risk of breast cancer (OR =0.70, 95% CI =0.53-0.91).ConclusionThese data suggest that the presence of Fas rs1800683 is an important risk factor for breast cancer, whereas FasL rs763110 may exert a protective effect against the onset of breast cancer.

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.
