Survival analysis of these lncRNAs revealed that 15 lncRNAs, including CTB-147N14.6, RP11-286H15.1, RP11-295D4.1, RHPN1-AS1, SNRPEP2, LINC01134, NRAV, NAP1L1P1, CMB9-22P13.1, MKLN1-AS, RP5-864K19.4, CTC-297N7.9, MAPKAPK5-AS1, MIR210HG, and AP001469.9, were closely associated with overall survival (OS) time of patients with hepatocellular carcinoma (Figure 1(b), log-rank test, P value < 0.05). Here, NAP1L1P1 is linked to hepatocellular carcinoma.
