PTPA and posterior cortical atrophy: Similarly, in a recent study Xie et al [41] demonstrated that in metastatic PCa cells restoring the expression of Disabled homolog 2 interacting protein (DAB2IP), a Ras GTPase-acting protein, leads to a reversal of EMT by interacting with PP2A and GSK-3β and decreasing nuclear β-catenin accumulation and its transcriptional activity.
