The results showed a significantly suppression of epithelial marker genes E-cadherin, collagen IV and cytokeratin, as well as increased expression of mesenchymal marker genes N-cadherin, snail, vimentin and S100A4 at 12 h after infection with SH0165 (108 CFU/mL) (Figures 6A,B). Here, SNAI1 is linked to infection.
