Expression and survival analyses demonstrated that, among these predicted lncRNAs, SNHG1 (Figure 7B), HCG18 (Figure 7E), NUTM2A-AS1 (Figure 7H) and ASB16-AS1 (Figure 7J), and SNHG6 (Figures 8H,I) were markedly upregulated in hepatocellular carcinoma and linked to poor prognosis. The gene discussed is SNHG6; the disease is hepatocellular carcinoma.
