Nuclear translocation and activation of β-Catenin signalling targets MMP-7, Cyclin D1, and TCF-1 is also enhanced in hepatocellular carcinoma cell lines with increased TOPK expression, a result supported by clinical data showing correlation between high-TOPK levels and nuclear β-Catenin localisation in tissues from hepatocellular carcinoma patients21. This evidence concerns the gene PBK and hepatocellular carcinoma.
