CDH1 and neoplasm: Western blot analysis revealed no difference in E-Cadherin or N-Cadherin expression, molecular markers of epithelial-mesenchymal transition (EMT) between E.coli-treated and control cells (Supplementary Fig. 3B), transwell migration, and scratch wounding assays showed no difference between Ctrl and E.coli group cells (Figure Supplementary Fig. 3C), indicating that microbiota did not affect the proliferation or migration of tumor cells.
