Among these six lncRNAs, EVX1-AS and ZNF667-AS1 have been predicted to be related to colon cancer in LncRNADisease V2.0 (http://www.rnanut.net/lncrnadisease/) (the latter was verified in the correlation analysis); RP11-798K3.2 and RP11-400N13.2 have been proven to be related to colon cancer by previous studies [34, 35]. This evidence concerns the gene EVX1 and malignant colon neoplasm.
