Recent reports from this laboratory and others have described a mesenchymal to epithelial reverting transition (MErT) to occur, where mesenchymal-like prostate cancer cell lines reexpress E-cadherin to become epithelial-like, and reestablish cellular adhesion during colonization within the liver tumor microenvironment [12, 13]. The gene discussed is CDH1; the disease is Familial prostate cancer.
