In addition, we conducted transwell assays to investigate HCC cells migration and invasion abilities and found that silence of Linc-KILH obviously inhibited the migration and invasion abilities in KRT19-positive Huh7 and MHCC-97H cells while no significant change was obtained in KRT19-negative Hep3B cells (Figure 4A and 4B). This evidence concerns the gene KILH and hepatocellular carcinoma.
