A functional HOTAIR rs920778 polymorphism does not contributes to gastric cancer in a Turkish population: a case–control study

Summary: | An aberrant up-regulation of
HOX transcript antisense intergenic RNA
(
HOTAIR
), a long non-coding RNA (lncRNA), is associated with human cancers including gastric cancer (GC) and worse clinicopathological features. A naturally occurring functional single nucleotide polymorphism (SNP) rs920,778 (C→T) in the intronic enhancer of
HOTAIR
gene has been demonstrated to affect HOTAIR expression and cancer susceptibility. To investigate the association of the
HOTAIR
rs920778 polymorphism on the risk of GC susceptibility in Turkish population, a hospital-based case–control study was carried out consisting of 104 GC and 209 healthy control subjects matched on age and gender. The genotype frequency of
HOTAIR rs920778
polymorphism was determined by using TaqMan Real-Time Polymerase Chain Reaction. No statistically significant differences were found in the allele or genotype distributions of the
HOTAIR
rs920778 polymorphism among GC and healthy control subjects (
P
> 0.05). Our results demonstrate that the
HOTAIR
rs920778 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. |
