Figure 5. Survival analysis and expression analysis of upstream key lncRNAs. (A–I) Prognostic value of the nine lncRNAs (RP11-429J17.2, TNRC6C-AS1, RP11-284F21.7, ZEB1-AS1, AC108488.4, AC007228.9, RP11-305O6.4, PCBP3-OT1, SLFNL1-AS1) in CRC by using GEPIA database. (J–M) Expression analysis grouped by tumor stage of the four lncRNAs (RP11-429J17.2, AC108488.4, PCBP3-OT1, ZEB1-AS1) in CRC by using TCGA project.
