HEIH and hepatocellular carcinoma: A number of lncRNAs, such as ATB (lncRNA activated by transforming growth factor-β)5, DANCR (differentiation-antagonizing non-protein-coding RNA)6, HEIH (lncRNA highly expressed in HCC)7, MVIH (lncRNA associated with microvascular invasion in HCC)8, and TP73-AS1 (P73 antisense RNA 1T)9, have been found to be dysregulated in and associated with HCC.
