CDH1 and neoplasm: In detail, a Fusobacterium nucleatum adhesin named FadA can bind to E-cadherin on tumor cells of the gut epithelium, modulating E-cadherin/β-catenin signaling, which results in more available molecules of β-catenin, triggering the EMT process leading to the invasiveness potential of the cells and ultimately increasing some oncogenes expression [48,49].
