SLC9A3-OT1 and hepatocellular carcinoma: Herein, our findings indicated that the restorative effect of miR-601 on cell proliferation, migration, invasion and apoptosis is triggered by lncRNA PP7080 knockdown, suggesting that lncRNA PP7080 acts as a molecular sponge for miR-601 and lncRNA PP7080/miR-601 axis may be essential elements for HCC progression.
