DIO3OS and hepatocellular carcinoma: We identified a cluster of lncRNAs (GBAP1, MCM3AP-AS1, SLC16A1-AS1, C3P1, DIO3OS, and HNF4A-AS1) as potential ceRNAs that regulate HCC carcinogenesis and progression, defining them as specific biomarkers to diagnose HCC and predict the prognosis and metastasis of patients with HCC.
