We compared the lncRNAs and mRNAs expression levels in GC tissues and normal gastric tissues in the GEPIA database, and the results showed that CDKN2B-AS1, H19, HOTTIP, MIR663AHG, and ZNF705A were highly expressed in GC, whereas LINC00643 and TMEM236 exhibited low expression in GC (Figures S8A–G). This evidence concerns the gene HOTTIP and gastric cancer.
