LncRNA NEAT1 polymorphisms and lung cancer susceptibility in a Chinese Northeast Han Population: A case-control study
2019
Abstract Background Long non-coding RNA Nuclear Paraspeckle Assembly Transcript 1 (NEAT1) is a novel lncRNA localized specifically to nuclear paraspeckles. The study analyses the association between NEAT1 genetic polymorphisms and the susceptibility of lung cancer in a Chinese Northeast Population. Methods The NEAT1 rs512715 and rs2239895 genetic polymorphisms were genotyped in 462 lung cancer cases and 559 controls by a Real-Time Polymerase Chain Reaction (PCR) with the TaqMan discrimination assay. Results Our study found that the polymorphisms of two SNPs increased or decreased the risk of lung cancer were not obvious, but statistical significance in non-small cell lung cancer and lung squamous cell carcinoma can be observed. Compared with homozygous CC genotype carriers, the GC genotype of rs2239895 was positively related to the risk of lung squamous cell carcinoma (OR 1.805, 95% CI, 1.168–2.789, P = 0.008). Similarly, associations between rs2239895 and lung squamous cell carcinoma risk were found (CC + GC vs. GG, OR 1.668, 95%CI, 1.093–2.545, P = 0.018) in dominant model. In stratified analysis for age, rs2239895 GC genotype was observed to increase the risk of non-small-cell lung cancer compared with CC genotype (OR 1.562, 95%CI, 1.029–2.371, P = 0.036). However, the study showed that negative correlation the lung cancer risk and rs512715 polymorphisms. There was no remarkable relationship between the both additive and multiplicative model about the two SNPs. Conclusions The polymorphisms rs2239895 were associated with the risk of lung squamous cell carcinoma. The interaction between the two SNPs and the cigarette smoking was no notable difference.
