Furthermore, The five lncRNAs in the prognostic signature (CAHM, DUXAP8, LINC00869, MKLN1-AS, and RHPN1-AS1), all had a significantly higher expression level in HCC tumor samples than normal samples in the TCGA-LIHC cohort (Figures 6C–G), implying that they probably act as oncogenic lncRNAs in the tumorigenesis of HCC. The gene discussed is RHPN1; the disease is hepatocellular carcinoma.
