[PMID: 34522797 PMCID: PMC8426517 DOI: 10.1016/j.heliyon.2021.e07867] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 12/14/2020] [Accepted: 08/20/2021] [Indexed: 12/24/2022] Open
Abstract
Aims Lung cancer is still the leading cause of cancer mortality in all over the world. Nicotine and its derivatives are the most well-known carcinogens that participate in both etiology and progression of lung cancer. The objective of the current study was to investigate whether single nucleotide polymorphisms (SNPs) rs1051730C > T in CHRNA3 and rs3842A > G in ABCB1, two genes contributing in the mechanism of disposition and metabolism of nicotine and its derivatives, could modify the risk of developing lung cancer, as well as nicotine dependence in Iranian. Main methods The genotyping analysis for these two SNPs was conducted in a case-control study of 108 lung cancer cases and 120 healthy controls using ARMS-PCR and Tetra-primer ARMS-PCR techniques. The correlation between studied SNPs and lung cancer was assessed by the regression analysis. Key findings We observed a significant association between lung cancer and rs1051730C > T by using four genetic models: allele (OR:1.83; 95% CI:1.24-2.6; p = 0.002), dominant (OR: 2.19; 95% CI:1.27-3.78; p = 0.005), recessive (OR: 2.25; 95% CI: 1.02-4.95; p = 0.043) and additive (TT vs CC: OR:3.25; 95% CI:1.38-7.60; p = 0.007, CT vs CC: OR:1.96; 95% CI:1.10-3.48; p = 0.021). Furthermore, a significant association between this variant and nicotine dependence (OR: 2.27; 95% CI: 1.52-3.39; p = 0.00005) was reported. However, no association was found for rs3842A > G. Significance The results suggested that the CHRNA3 rs1051730C > T via a smoking-dependent manner could modify susceptibility to lung cancer among Iranian population.

Abstract
Abstract
Background
Gene-gene and gene-environment interactions play an important role in cancer susceptibility. In this work, we studied the association of XRCC1 rs25487, ERCC1 rs735482, and CHRNA3 rs1051730 variants with lung cancer and assessed the modulatory effect of potential interaction between these variants on disease risk.
Results
In this study, 86 primary lung cancer patients and 64 control subjects were genotyped for CHRNA3 rs1051730, XRCC1 rs25487, and ERCC1 rs735482 by real-time PCR. The frequency of the three studied variants was higher among lung cancer patients than in control subjects, but with no statistical significance. ERCC1 rs735482 variant was associated with 6.9-fold increased risk to develop lung cancer among smokers (p = 0.03). Concomitant presence of CHRNA3 and ERCC1 wild alleles was associated with 2.7-fold elevated risk of lung cancer (p < 0.0001), while concomitant presence of CHRNA3 rs1051730 variant allele with ERCC1 wild allele was associated with 20-fold elevated risk (p < 0.000). Concomitant presence of both variants, ERCC1 rs735482 and CHRNA3 rs1051730, was associated with 9.9-fold elevated risk (p < 0.0001). Meanwhile, the concomitant presence of XRCC1 rs25487 with either ERCC1 rs735482 or CHRNA3 rs1051730 or both was not associated with increased risk of the disease.
Conclusion
Our results emphasize the role of gene-gene interaction in the pathogenesis of lung cancer. Large-scale further studies to clarify the underlying mechanisms are needed.

Abstract
Objective The genetic polymorphism (rs16969968 in CHRNA5, and rs1051730 in CHRNA3 genes) were recently shown to be associated with risk of LC. The aim of this study is to elucidate whether they predispose Palestinian individuals to lung cancer, and how is this related to smoking. Results Frequency of the rs16969968-A allele was significantly higher in the case group (36.7%) than in normal controls (17.5%; P = 0.022; OR = 6.83 for AA and 2.81 for AG genotypes). The frequency of rs1051730-T allele was also significantly higher in the case group (46.7%) than in the control group (22.5%; P = 0.001; OR = 2.20 for TC and 13.22 for TT genotypes). Frequency of rs16969968-A allele was higher in smokers (29.1%) than nonsmokers (15.7%) regardless of lung cancer; similarly, frequency of rs1051730-T allele was also higher in smokers than in smokers (46.7% vs 22.5%, respectively). The higher the proportion of the risk allele (rs16969968-A and rs1051730-T), the higher the mean number of daily consumed cigarettes (P = 0.006). Carrying rs16969968-A and/or rs1051730-T alleles results in an increased risk to lung cancer probably by increasing the individual’s tendency for heavy smoking. The allelic frequency of the rs16969968-A and rs1051730-T alleles among normal Palestinian controls is similar to different populations worldwide.

Polymorphism of rs9387478 correlates with overall survival in female nonsmoking patients with lung cancer. Int J Biol Markers 2016; 31:e144-52. [PMID: 26689248 DOI: 10.5301/jbm.5000180] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/08/2015] [Indexed: 12/25/2022]
Abstract
BACKGROUND Our previous study identified rs9387478 as a new susceptibility locus associated with lung cancer in never-smoking women in Asia; however, the clinical and prognostic significance of this finding is not known. METHODS We analyzed the relationship between the rs9387478 single nucleotide polymorphism and i) clinical parameters and ii) overall survival time in 505 female nonsmoking lung cancer patients, using the chi-square test and Kaplan-Meier analysis with the log-rank test, respectively. We further established the epidermal growth factor receptor (EGFR) mutation status and assessed its association with rs9387478 genotypes as well as the efficacy of EGFR tyrosine kinase inhibitors. RESULTS The frequency of the AA genotype was significantly higher in the EGFR-mutation-negative group than in the EGFR-mutation-positive group (32% vs. 16%, χ2 = 13.025, p = 0.011). Patients with the CC genotype had a better overall survival time than patients with the AA/AC genotype (median survival time: 54.2 vs. 32.9 months, χ2 = 4.593, p = 0.032). The distribution of rs9387478 genotypes differed according to the clinical disease stage. CONCLUSIONS This study indicates that the rs9387478 genotype was associated with overall survival in nonsmoking female patients with lung cancer, although it was not significant after adjusting for multiple testing. The identification of the location of the rs9387478 single nucleotide polymorphism in the genomic interval containing the DCBLD1 and ROS1 genes, together with the finding that the rs9387478 polymorphism correlates with EGFR mutation status, may have important implications for therapeutic approaches targeting EGFR or ROS1 in patients with lung cancer.

Abstract
The early genome-wide association studies (GWAS) found a significant association between lung cancer and rs1051730 (15q25) polymorphism. However, the subsequent studies reported consistent and inconsistent results in different populations. Three meta-analysis studies were thus performed to reevaluate the association. But their results remain inconsistent. After that, some new GWAS studies reported conflicting results again. We think that the divergence of these results may be due to small-scale samples or heterogeneity among different populations. Therefore, we reevaluated the association by collecting more samples (N = 33,617 cases and 116,639 controls) from 31 studies, which incorporate 8 new studies and 23 previous studies used by one or more of the three meta-analysis studies. We observed a significant association between lung cancer and rs1051730 in pooled population by using allele (OR = 1.30, 95% CI = 1.27–1.34, P < 0.0001), dominant (OR = 1.41, 95% CI = 1.29–1.55, P < 0.0001), recessive (OR = 1.53, 95% CI = 1.42–1.65, P < 0.0001) and additive (OR = 1.75, 95% CI = 1.61–1.90, P < 0.0001) models. Through the subgroup analysis, we observed a significant heterogeneity only in East Asian population (P = 0.006, I2 = 66.9%), and the association is significant in all subgroups (OR = 1.2976, 95% CI = 1.2622–1.3339 (European ancestry), OR = 1.5025, 95% CI = 1.2465–1.8110 (African), OR = 1.7818, 95% CI = 1.3915–2.2815 (East Asian), P < 0.0001). We believe that these results will contribute to understanding the genetic mechanism of lung cancer.

Abstract
Many studies have examined the association between the CHRNA3 rs1051730 polymorphism gene polymorphisms and lung cancer risk in various populations, but their results have been inconsistent. The PubMed was searched for case-control studies published up to Jan 01, 2015. Data were extracted and pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. In this meta-analysis, we assessed four published studies involving comprising 2,890 lung cancer cases and 2,521 controls of the association between CHRNA3 rs1051730 polymorphism and lung cancer risk. For the T allele carriers (C/T + T/T) and the homozygote T/T, the pooled ORs for all studies combined 2,890 cases and 2,521 controls were 1.93 (95% CI =1.48-2.53, P=0.34 for heterogeneity) and 1.63 (95% CI =1.27-1.99, P=0.46 for heterogeneity), when compared with the homozygous wild-type genotype (C/C). There was no observable publication bias for both polymorphisms. These results from the meta-analysis suggest that CHRNA3 rs1051730 polymorphism contributes to risk of lung cancer among Asian population.

Abstract
Lung cancer is the leading cause of cancer-related deaths worldwide that result from the combined effected of smoking exposure and genetic susceptibility. CHRNA3, a nicotinic acetylcholine receptor gene, was associated with lung cancer risk. The aim of this study was to identify whether CHRNA3 polymorphisms increase lung cancer risk directly or indirectly through smoking behavior in the Chinese Han individuals. We conducted a case-control study including 228 individuals with lung cancer and 301 healthy individuals. Seventeen known SNPs within CHRNA3 were selected for genotyping. Odds ratios (OR) and 95 % confidence interval (CI) were calculated by unconditional logistic regression with adjustment for gender and age. Two SNPs (rs8042059 and rs7177514) showed a 1.54-fold (p = 0.036; 95 % CI = 1.03-2.32) and 1.52-fold (p = 0.043; 95 % CI = 1.01-2.27) increased risk for lung cancer in smokers, respectively. Rs8042059 also showed a significant association for variant genotypes (CA/AA) compared with the wild-type genotype (CC), with an OR = 1.84 (p = 0.042; 95 % CI, 1.02-3.33) in the dominant model. In addition, the haplotype analysis found that the haplotypes "TCAC" and "CTGT," composed of rs938682, rs12914385, rs11637630, and rs2869546, were associated with a 1.79-fold and 501-fold increased lung cancer risk, respectively. However, the polymorphisms of all SNPs were not significantly different between controls and cases among general or nonsmokers population. Rs8042059 and rs7177514 may increase lung cancer risk indirectly through smoking behavior in the Chinese Han population.
