The canonical Wnt signaling is frequently activated in human hepatocellular carcinoma (HCC). We previously demonstrated that upregulation of Frizzled-7 receptor (FZD7) in HCC was associated with nuclear accumulation of wild-type beta-catenin. Here, we investigated Wnt ligand(s) that may activate the Wnt/beta-catenin pathway through FZD7 in HCC cells.
