Polymorphism in lncRNA AC008392.1 and its interaction with smoking on the risk of lung cancer in a Chinese population.

ABSTRACT: Purpose:To evaluate the association between rs7248320 in lncRNA AC008392.1 and the risk of lung cancer, this case-control study was carried out in a Chinese population. This study also evaluated the gene-environment interaction between rs7248320 and exposure to smoking status on the risk of lung cancer. Patients and methods:We conducted a hospital-based case-control study including 512 lung cancer cases and 588 healthy controls. The association between rs7248320 and the risk of lung cancer was analyzed, and the gene-environment interaction was estimated on an additive scale. Results:The variant genotype of rs7248320 was significantly related to the risk of non-small-cell lung cancer (NSCLC). Individuals carrying homozygous GG genotype had decreased risk of NSCLC, compared with individuals carrying the homozygous wild AA genotype/heterozygote GA genotype (adjusted odds ratio [OR] =0.653, 95% confidence interval [CI] =0.442-0.966, P=0.033). Moreover, in the subgroup of ages, there were statistically significant associations between rs7248320 and the risk of lung cancer and NSCLC in the population over 60 years of age. Compared with individuals carrying genotypes AA/GA, individuals with genotype GG had the lower risk of lung cancer and NSCLC (adjusted ORs were 0.579 and 0.433, 95% CIs were 0.338-0.994 and 0.231-0.811, P-values were 0.048 and 0.009, respectively). Compared with homozygote AA, the homozygote GG was associated with a decreased risk in NSCLC (OR =0.456, 95% CI =0.235-0.887, P=0.021). There were no statistically significant results in gene-environment interactions on an additive scale. Conclusion:These findings suggest that lncRNA AC008392.1 rs7248320 may be involved in genetic susceptibility to NSCLC in a Chinese population.

Project description:IntroductionRs2292832 is a single nucleotide polymorphism located in the precursor of mir-149 and was reported to be associated with varieties of malignancies. So far, the effect of miR-149 rs2292832 polymorphism on lung cancer risk was unclear. In addition, cooking oil fume exposure was demonstrated to be an important environmental risk factor in Chinese female. The aim of the present study was to evaluate the associations of rs2292832 polymorphism, cooking oil fume exposure and multiplicative interaction of cooking oil fume exposure and rs2292832 polymorphism with lung cancer risk in Chinese non-smoking female population.MethodsThe present study was a hospital-based case-control study conducted in Chinese non-smoking females. 555 lung cancer patients and 395 cancer-free controls were interviewed to collect demographic data and exposure status of environmental risk factors, and then donate 10 ml venous blood which was used to be genotyped by Taqman allelic discrimination method. The statistical analyses were performed on SPSS 13.0 software.ResultsThe association between miR-149 rs2292832 polymorphism and risk of lung cancer(TC vs. TT: OR = 1.006, 95%CI = 0.767-1.321, P = 0.963; CC vs. TT: OR = 0.41, 95%CI = 0.532-1.329, P = 0.458; Dominant model: OR = 0.965, 95%CI = 0.745-1.251, P = 0.788; Recessive model: OR = 0.816, 95%CI = 0.528-1.259, P = 0.357, adjusted for age), non-small cell lung cancer(TC vs. TT: OR = 1.006, 95%CI = 0.767-1.321, P = 0.963; CC vs. TT: OR = 0.841, 95%CI = 0.532-1.329, P = 0.458, adjusted for age), lung adenocarcinoma(TC vs. TT: OR = 0.944, 95%CI = 0.700-1.273, P = 0.707; CC vs. TT: OR = 0.801, 95%CI = 0.485-1.323, P = 0.386, adjusted for age) and squamous cell carcinoma(TC vs. TT: OR = 1.025, 95%CI = 0.641-1.638, P = 0.919; CC vs. TT: OR = 0.792, 95%CI = 0.346-1.813, P = 0.581, adjusted for age) were all not statistically significant. Result of Logistic regression showed that the multiplicative interaction of cooking oil fume exposure and rs2292832 polymorphism was not statistically significant (P = 0.063 for lung cancer and P = 0.064 for lung adenocarcinoma).ConclusionMicroRNA-149 rs2292832 polymorphism may not be associated with lung cancer risk in Chinese non-smoking female.

Project description:BackgroundBoth genetic polymorphisms and environmental risk factors play important roles in the development of human chronic diseases including lung cancer. This is the first case-control study of interaction between polymorphisms in pre-miRNA genes and cooking oil fume exposure on the risk of lung cancer.MethodsA hospital-based case-control study of 258 cases and 310 controls was conducted. Six polymorphisms in miRNAs were determined by Taqman allelic discrimination method. The gene-environment interactions were assessed on both additive and multiplicative scale. The statistical analyses were performed mostly with SPSS.ResultsThe combination of the risk genotypes of five miRNA SNPs (miR-146a rs2910164, miR-196a2 rs11614913, miR-608 rs4919510, miR-27a rs895819 and miR-423 rs6505162) with risk factor (cooking oil fume exposure) contributed to a significantly higher risk of lung cancer, and the corresponding ORs (95% confidence intervals) were 1.91(1.04-3.52), 1.94 (1.16-3.25), 2.06 (1.22-3.49), 1.76 (1.03-2.98) and 2.13 (1.29-3.51). The individuals with both risk genotypes of miRNA SNPs and exposure to risk factor (cooking oil fumes) were in a higher risk of lung cancer than persons with only one of the two risk factors (ORs were 1.91, 1.05 and 1.41 for miR-146a rs2910164, ORs were 1.94, 1.23 and 1.34 for miR-196a2 rs11614913, ORs were 2.06, 1.41 and 1.68 for miR-608 rs4919510, ORs were 1.76, 0.82 and 1.07 for miR-27a rs895819, and ORs were 2.13, 1.15 and 1.02 for miR-423 rs6505162, respectively). All the measures of biological interaction indicate that there were not indeed biological interactions between the six SNPs of miRNAs and exposure to cooking oil fumes on an additive scale. Logistic models suggested that the gene-environment interactions were not statistically significant on a multiplicative scale.ConclusionsThe interactions between miRNA SNPs and cooking oil fume exposure suggested by ORs of different combination were not statistically significant.
