In the previous studies, the actions of numerous lncRNAs, such as ubiquitin-conjugating enzyme E2C pseudogene 3 (UBE2CP3) 17, lnc-DILC (lncRNA downregulated in liver cancer stem cells) 18, and cancer susceptibility candidate 2 (CASC2) 19, have been confirmed in hepatocarcinogenesis. The gene discussed is UBE2CP3; the disease is liver cancer.
