LINC00680 and hepatocellular carcinoma: We also examined the expression levels of LINC00680 in L02, SNU-182, SK-hep1, Huh7, SNU-449, Hep3B, BEL-7405, and LM3 cell lines, and found a remarkably higher expression of LINC00680 in five out of all the seven HCC lines (SNU-182, SK-hep1, SNU-449, Hep3B, and BEL-7405) than that in the normal liver cell line (L02) (Fig. 1e).
