FOXN3 and hepatocellular carcinoma: We measured the endogenous expression of the FOXN3 mRNA and protein in ten HCC cell lines (SMMC-7721, Huh7, PLC/PRF/5, LM3, 97L, SK-Hep1, HCC-LY5, HCC-LY10, 97H and Li7) and an immortalized liver cell line (L02) by western blotting and qRT-PCR (Figure 1E and 1F).
