Intriguingly, almost no changes in the expression of vimentin (VIM, which acts as one of major mesenchymal markers) were observed, but this was instead accompanied by modestly increased abundance of the epithelial marker E-cadherin-associated α-catenin, in Nrf1α−/−-derived xenograft tumours (Fig. S5a). The gene discussed is VIM; the disease is neoplasm.
