TUG1 and hepatocellular carcinoma: The result showed that TUG1 expression was exceptionally facilitated in four human HCC cell lines HAK-2,Hep3B,Huh7 and LC05 compared with normal liver cell line THLE-2 (Fig. 1e), and that the miR-216b-5p expression was exceptionally constrained in four HCC cell lines than that in normal liver cell (Fig. 1f).
