HOTAIR and colorectal carcinoma: They chose four HOTAIR polymorphisms (rs7958904G>C, rs920778T>C, rs4759314A>G, and rs1899663G>T), conducting genotype frequencies and Cox-regression analysis, and demonstrated that HOTAIR rs7958904G>C could be a potent prognostic biomarker for CRC, which was positively associated with CRC prevalence and mortality.
