Figure 4. CLCA4 inhibits cell migration and invasion in HCC cell lines. (A, B) CLCA4 silenced in Hep-3B cells and promoted cell migration and invasion. (C, D) CLCA4 up-regulated in SMMC-7721 cells and inhibited cell migration and invasion. (E) Lung H&E staining of nude mice inoculated Hep-3B and SMMC-7721 transfected cells via tail vein. The number of lung tumor nodules in each group were also calculated, * P < 0.05.
