KLF4 and hepatocellular carcinoma: In order to confirm that KLF4 may affect the HCC cell growth and invasion through miR-153, miR-506 and miR-200b, we overexpressed the antisense for miR-153, miR-506 and miR-200b in KLF4-expressing HepG2 cells (Figure 5A–5B), and compared to HepG2-KLF4 cells and HepG2-scr cells in both MTT and transwell cell migration assay.
