The results showed that nine lncRNAs were highly expressed in HCC patients with relapse compared with those without relapse (Figure S2 and Figures 6A, D), and the expression levels of SNHG3 and LINC00205 were closely correlated with HCC grade and stage (Figures 6B, C, E, F). This evidence concerns the gene SNHG3 and hepatocellular carcinoma.
