PVT1 and hepatocellular carcinoma: Similarly, in another study which analyzed lncRNA expression using bioinformatics, seven lncRNAs (PVT1, LINC01138, LINC02499, AL355488.2, FGF14-AS2, MAFG-AS1 and LINC00261) were significantly associated with overall survival and collectively were identified as a prognostic signature for patients with HBV-related HCC (112).
