PCAT6 and hepatocellular carcinoma: As shown in Figure 9 and Figure S5, the expression level of lncRNAs (TMCC1-AS1, PCAT6, ACVR2B-AS1) was significantly associated with the prognosis of HCC, and patients with high lncRNAs expression had poor survival rates (pvalue < 0.001); however, the expression level of lncRNAs (AC092418.2, SACS-AS1) was not associated with the prognosis of HCC.
