Genetic variants in lncRNA HOTAIR are associated with lung cancer susceptibility in a Chinese Han population in China: a case-control study.

ABSTRACT: Purpose:HOX transcript antisense RNA (HOTAIR) plays important roles in carcinogenesis of various kinds of malignant tumors, including lung cancer. Single nucleotide polymorphisms (SNPs) in HOTAIR were reported to be associated with susceptibility of several kinds of cancers. The present study assessed the associations between three SNPs (rs4759314, rs12826786, and rs920778) and lung cancer susceptibility, as well as gene-environment interaction between smoking exposure and the polymorphisms. Patients and methods:A case-control study including 551 patients and 543 healthy controls was performed. The associations between SNPs and lung cancer susceptibility were assessed by logistic regression model. Results:rs4759314 was observed to increase the susceptibility of lung cancer, lung adenocarcinoma, squamous lung cancer, and small cell lung cancer statistically significantly (OR of 4.048 for lung cancer; 3.584 for lung adenocarcinoma; 4.671 for squamous lung cancer; 4.502 for small cell lung cancer). In stratified analysis for sex and smoking exposure, rs4759314 GG and AG genotype was also observed to increase the risk of lung cancer statistically significantly (OR of 5.221 for male; 3.491 for female; 3.653 for nonsmoking individuals; 4.458 for smoking individuals). Results of gene-environment interaction analysis showed that there was no interaction between smoking exposure and rs4759314 on additive scale. Results of logistic regression model suggested that the interaction between smoking and rs4759314 was statistically significant on multiplicative scale. rs12826786 CT genotype carriers and T allele could decrease the risk of developing lung cancer (OR of 0.751 for CT carriers; 0.785 for T allele), and in dominant model, TC and TT genotype carriers also have a 0.249-fold decrease risk compared with CC genotype carriers. In stratified analysis for smoking exposure, TC and TT have a 0.432-fold decreased risk compared with CC genotype carriers. Conclusion:HOTAIR rs4759314 and rs12826786 were associated with lung cancer susceptibility in Chinese Han population.

Project description:BackgroundLOC105371267, also known as PR-lncRNA1, was reported to be a p53-regulated long noncoding RNA (lncRNA), which played an essential role in the pathogenesis of breast cancer (BC). We aimed to observe the potential association between LOC105371267 polymorphisms and BC risk in Northern Chinese Han females.MethodsTotally, 555 healthy individuals and 561 patients with BC were recruited. Five candidate SNPs (rs6499221, rs3931698, rs8044565, rs3852740, and rs111577197) of LOC105371267 were genotyped with the Agena MassARRAY system. Odds ratio (OR) and 95% confidence intervals (CIs) were applied to evaluate the relationship of LOC105371267 genetic polymorphisms with BC susceptibility. Additionally, stratification analysis based on clinical features and haplotype analysis were also conducted. Finally, multifactor dimensionality reduction (MDR) analysis was performed to assess the SNP-SNP interaction among LOC105371267 variants, and false-positive report probability (FPRP) analysis was used to validate the result of this study.ResultsIn this study, rs3931698 was a protective factor of BC in total (GG homozygote: OR = 0.30, 95% CI: 0.11-0.82, p=0.018; recessive model: OR = 0.30, 95% CI: 0.11-0.84, p=0.021). In stratification analysis based on the average age of 52 years and clinical characteristics (PR status, III-IV TNM stage), rs3931698 was also demonstrated to be associated with BC susceptibility. In addition, rs6499221 and rs3852740 were also associated with BC susceptibility among patients at age <52 years and patients with BC in a positive status. Thus, the haplotype analysis had a negative result for the incidence of BC (p > 0.05), and haplotype consisting of rs8044565 and rs111577197 was nonsignificantly associated with the BC risk. Finally, MDR and FPRP analyses also validated the result of this study.ConclusionPolymorphisms rs3931698, rs6499221, and rs3852740 of LOC105371267 were found to be associated with the risk of BC in total, and stratification analysis in the Northern Chinese Han females suggested that LOC105371267 variants might be helpful to predict BC progression.
