Abstract

BackgroundThe HOX transcript antisense intergenic RNA (HOTAIR) is a well-known long noncoding RNA (lncRNA) that plays a critical role in biological processes in most cancers. However, the function of HOTAIR in bladder cancer remains largely unknown. In this study, we hypothesize that tag single nucleotide polymorphisms (tagSNPs) in HOTAIR are associated with bladder cancer (BCa) risk. MethodsWe performed a hospital-based case-control study of 1050 cases and 1407 controls to investigate the associations between tagSNPs and the risk of BCa in a Chinese population. ResultsWe found that individuals with the rs874945 AG/AA genotype had a significantly increased risk of BCa compared with those carrying the GG genotype, with an odds ratio (OR) of 1.23 [95% confidence interval (CI) = 1.04–1.46, P = 0.014]. The subsequently stratified analyses showed that the increased risk was more pronounced in subgroups of older subjects (age > 60 years), never smokers and subjects without pack-years of smoking. Interactive analysis showed that there was no interaction effect between smoking status and rs874945. ConclusionOur study showed that rs874945 in HOTAIR was associated with BCa risk in a Chinese population.
