FTX and hepatocellular carcinoma: To elucidate whether miR-545 plays pivotal roles in Ftx-induced HCC cell proliferation, miR-545 was knocked down bymiR-545 inhibitor in Ftx-overexpressing SMMC-7721 cells and miR-545 was restored by miR-545 mimics in Ftx-suppressive Hep3B cells (P<0.05, Figure 5C).
