Cancer&Entry Information
| Cancer Name | esophageal squamous cell carcinoma |
| ICD-0-3 | NA |
| Methods | qPCR, Dual luciferase reporter assay etc. |
| Sample | ESCC tissues |
| Expression Pattern | down-regulated |
| Function Description | We found that subjects with the rs920778 TT genotype had significantly lower HOTAIR RNA levels than those with the CC genotypes in normal esophagus tissues. We found that the HOTAIR rs920778 TT carriers had a 1.37-fold, 1.78-fold and 2.08-fold increased ESCC risk in Jinan, Shijiazhuang and Huaian populations, respectively, compared with the CC carriers. During inspecting functional relevance of the rs920778 SNP, we identified a novel intronic HOTAIR enhancer locating between +1719bp and +2353bp from the transcriptional start site through reporter assays. Moreover, there is an allelic regulation of rs920778 on HOTAIR expression via this enhancer in both ESCC cell lines and normal esophageal tissue specimens, with higher HOTAIR expression among T allele carriers. |
