Similarly, Marques et al. (2018) reported that infection with the H. pylori 26695 strain significantly reduced E-cadherin, β-catenin, occludin, and ZO-1 protein levels in both MKN-74 and NCI-N87 cell lines and also caused delocalization of these junctional proteins (Marques et al., 2018). This evidence concerns the gene CDH1 and infection.
