H. pylori is able to trigger the expression of MMP, which is a proteolytic enzyme that has a role in maintaining and remodelling the interaction between epithelial cells and the basal membrane [19, 20]. A study, conducted by Bebb JR et al, found that gastric biopsy specimens from a positive H. pylori subject will show in a higher level of MMP-7 protein in the antrum and corpus . A similar result is found from the study conducted by Wroblewski et al, which concluded that the MMP-7 expression in the antrum and corpus increased with the presence of H. pylori .
