Survival analysis in colorectal cancer with the GEPIA database showed that of these 83 lncRNAs, only 9 lncRNAs (RP11-429J17.2, TNRC6C-AS1, RP11-284F21.7, ZEB1-AS1, AC108488.4, AC007228.9, RP11-305O6.4, PCBP3-OT1, SLFNL1-AS1) had statistical significance in prognosis of colorectal cancer (Figure 5A–5I). This evidence concerns the gene ZEB1 and colorectal cancer.
