CDH2 and bladder transitional cell carcinoma: Western blotting of EMT-related proteins (E-cadherin, N-cadherin, Vimentin and Slug) revealed an upregulation of E-cadherin and a downregulation of N-cadherin, Vimentin and Slug in BLCA cells after RhoB overexpression (Fig. 6h), consistent with observations after ZOL treatment (Fig. 3i).
