Figure 1From: DKK1 promotes hepatocellular carcinoma cell migration and invasion through β-catenin/MMP7 signaling pathwayDKK1 is overexpressed in HCC cells. A: The mRNA expression of DKK1 in normal liver cell line (QSG7701) and HCC cell lines (HepG2, SMMC7721, Huh7 and Bel7402). GAPDH was used as an internal control. B: Western blot analysis of DKK1 in the same cell lines as described in A. β-actin served as a loading control.Back to article page
