PICSAR and hepatocellular carcinoma: We analyzed the expression and prognosis of these lncRNAs in HCC and revealed that 34 LncRNAs were expressed upregulated in HCC (Supplementary Figure 1 and Figure 7D–7I), while only ACVR2B-AS1 (Figure 7D, P = 0.022), LINC00667 (Figure 7E, P = 0.0022), CYTOR (Figure 7F, P = 1.2e-30), MIR4435-2HG (Figure 7G, P = 4.1e-35), DANCR (Figure 7H, P = 3.2e-7), and PICSAR (Figure 7I, P = 0.0075) that were up-regulated in HCC and linked to poor prognosis (Figure 7D, P = 0.0034, Figure 7E, P = 0.0056, Figure 7F, P = 3.1e-05, Figure 7G, P = 0.0012, Figure 7H, P = 0.0027, Figure 7I, P = 0.00034).
