PTK6 and hepatocellular carcinoma: We found that PSPC1 overexpression can also be a contextual activator to stimulate the nuclear translocation of β-catenin with enhanced interaction of PSPC1 and β-catenin in the nucleus and to upregulate Wnt3a autocrine signaling to potentiate synergistic oncogenic progression mediated by PSPC1 and PTK6 in HCC cells.
