Genetic polymorphisms and haplotypes of TRAIL gene correlate with NSCLC susceptibility in a group of Chinese patients.

ABSTRACT: The association between genetic polymorphisms and haplotypes of TNF-related apoptosis-inducing ligand (TRAIL) and the NSCLC development was investigated in 592 Chinese patients and the prevalence of G1525A, G1588A, and C1595T gene polymorphisms compared between the NSCLC patients and control group in this study. It was found that the frequencies of variant allele A and genotype GA+AA of G1525A were significantly lower and those of variant alleles A and T of G1588A and C1595T significantly higher in the NSCLC patients compared with those in control. The frequencies of variant allele T and genotype CT+TT of C1595T were significantly higher in stage III and IV than in stage I and II of the patients. Moreover, the frequencies of variant allele A and genotype GA+AA of G1525A were significantly higher in stage III and IV than in stage I and II of the patients. In addition, TRAIL gene variants G1525A/G1588A/C1595T were found to be in complete linkage disequilibrium in all patients. Compared with the healthy people, the frequency of AAT haplotype was significantly lower whereas that of GAT haplotype significantly higher in NSCLC patients. The results indicated that the genetic polymorphisms and haplotypes of TRAIL gene correlated significantly with the NSCLC susceptibility in the group of Chinese patients.

Project description:STUDY DESIGN:Meta-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. OBJECTIVE:To investigate whether or not the FASL and TRAIL genetic polymorphisms are associated with susceptibility to IDD in Chinese Han population. SUMMARY OF BACKGROUND DATA:FASL 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. METHODS:We 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. RESULTS:Six 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. CONCLUSION:The present meta-analysis demonstrated that FASL and TRAIL polymorphisms were significantly associated with susceptibility to IDD in Chinese Han population. LEVEL OF EVIDENCE:1.

Project description:Hepatoblastoma is one of the malignant liver tumors in children. However, genetic mechanisms underpinning the initiation of hepatoblastoma remain largely unclear. The previous study showed that lin-28 homolog B (LIN28B) might play a role in the development of hepatoblastoma. To detect the association between LIN28B gene polymorphisms and hepatoblastoma risk in Chinese children, we conducted a five-center case-control study of 275 hepatoblastoma patients and 1018 cancer-free controls. Four potentially functional polymorphisms were genotyped using the Taqman method. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the strength of the associations. We found that the rs314276 C>A polymorphism (AA vs. CC: adjusted OR=2.05, 95% CI=1.36-3.10, P=0.0006; AA vs. CA/CC: adjusted OR=2.11, 95% CI=1.43-3.12, P=0.0002) and rs9404590 T>G (GG vs. TT: adjusted OR=1.89, 95% CI=1.20-3.00, P=0.007; GG vs. TT/TG: adjusted OR=1.87, 95% CI=1.20-2.92, P=0.006) were associated with increased hepatoblastoma risk. Combination analysis of risk genotypes showed that patients with four risk genotypes had a higher chance of developing hepatoblastoma than carriers of 1 to 3 risk genotypes. Stratification analysis showed the significant association between the rs314276 AA genotype and hepatoblastoma risk in both age and sex groups, as well as clinical stages III+IV cases. The rs9404590 GG genotype was associated with hepatoblastoma risk in participants' ?17 months, in females, and for those with clinical stages III+IV disease. Furthermore, four risk genotypes confer higher hepatoblastoma susceptibility in both age and sex groups, as well as groups with clinical stages III+IV disease. Genotype-based gene expression analysis confirmed that the rs9404590 T>G polymorphism was significantly associated with altered LIN28B gene expression. We further validated our findings using false-positive probability analysis. This finding suggested that LIN28B gene polymorphisms may be associated with an increased predisposition to hepatoblastoma.
