BackgroundThe HOX transcript antisense intergenic RNA (HOTAIR), a well-known long noncoding RNA (lncRNA), has been widely identified to participate in pathogenesis of multiple cancers. An aberrant up-regulation and biological functions have been observed in gastric cancer (GC). A common single nucleotide polymorphism (SNP) (rs12826786 C>T) at the HOTAIR has been reported to influence HOTAIR expression, but its association with GC has yet to be investigated in Turkish population.AimThe aim of the present study was to investigate whether HOTAIR rs12826786 C>T polymorphism could be involved in the risk of GC susceptibility in Turkish population.MethodsWe genotyped HOTAIR rs12826786 C>T polymorphism in 312 Turkish individuals including 105 GC patients and 207 healthy controls matched on age and gender by a Real-Time Polymerase Chain Reaction (PCR) with the TaqMan assay.ResultsNo statistically significant differences were found in the allele or genotype distributions of the HOTAIR rs12826786 C>T polymorphism among GC and healthy control subjects (P > 0.05).ConclusionsOur results demonstrate that the HOTAIR rs12826786 C>T polymorphism has not been in any major role in genetic susceptibility to gastric carcinogenesis, at least in the population studied here. Independent studies are needed to validate our findings in a larger series, as well as in patients of different ethnic origins.
