Therefore, we mined the UALCAN database [21] (http://ualcan.path.uab.edu/) against our list of differentially expressed genes and found five interesting lncRNAs (NEAT1, C11orf95, DIO3OS, HCG18, SNHG12) which are significantly expressed in HCC compared with normal tissues (Fig. 1c and Supplementary Fig. 1b). The gene discussed is HCG18; the disease is hepatocellular carcinoma.
