ARTICLE HIGHLIGHTS
Research background
The role of existing tumor biomarkers for cholangiocarcinoma (CCA) diagnosis, remains controversial due to their low sensitivity and specificity. Increasing evidence has implicated long non-coding ribonucleic acid (lncRNA) polymorphisms with cancer susceptibility in a variety of tumor types.
Research motivation
The association between lncRNA homeobox protein transcript antisense intergenic RNA (HOTAIR) polymorphisms and CCA risk has not been reported yet.
Research objectives
To investigate the role of lncRNA HOTAIR polymorphisms in CCA susceptibility.
Research methods
Case-control study on lncRNA HOTAIR genotypes.
Research results
HOTAIR rs4759314 AG and GG genotypes were associated with a significantly increased CCA risk [P = 0.004, odds ratio: 3.13; 95% confidence interval: 1.65-5.91 and P = 0.005, odds ratio: 12.31; 95% confidence interval: 1.48-101.87, respectively]. However, no significant associations of HOTAIR rs920778, and rs7958904 were detected. Similarly, we found no significant associations between rs4759314 AA genotype and CCA susceptibility.
Research conclusions
HOTAIR rs4759314 AG and GG genotypes may be implicated with CCA development and may serve as a potential diagnostic biomarker.
Research perspectives
To further investigate the biological role of HOTAIR on CCA pathogenesis.
