MSI2 support of the expression of proteins associated with both epithelial (E-cadherin and ZO-1) and mesenchymal (TGFβ1) identity is consistent with a role of MSI2 reported previously in non-small cell lung cancer (NSCLC), in which MSI2 overexpression induced a mixed differentiation phenotype [9]. The gene discussed is CDH1; the disease is non-small cell lung carcinoma.
