TUSC7 and hepatocellular carcinoma: LncRNAs act as competitor endogenous RNAs (ceRNAs) that sequester and inhibit miRNAs that promote or inhibit EMT, the most-studied epithelial lncRNAs (EMT suppressors) are GAS5 (growth arrest-specific 5), DREH (down-regulated in hepatocellular carcinoma), TUSC7 (tumor suppressor candidate 7), NBR2 (neighbor of BRCA1 LncRNA 2), and NEF [59,60].
