The results in combination with the survival analysis and expression analysis, showed that GSEC, PTPRG-AS1, CYTOR, DANCR, TRAF3IP2-AS1 and DLEU2 were significantly upregulated in HCC, and their upregulation was associated with poor prognosis in HCC patients (Figure 15C). The gene discussed is DANCR; the disease is hepatocellular carcinoma.
