The control of H. pylori-mediated gastric cancer development and progression through YAP/TAZ signal regulation


ABSTRACT: Helicobacter pylori(H. pylori), a gastrointestinal pathogen, is known to increase the risk of gastric cancer by activating chronic pro-inflammatory signaling pathways in epithelial cells. Cytotoxin-related protein A (CagA) is known to play an important role in gastric cancer development. CagA has been reported to induce tumors by inducing overexpression of YAP/TAZ, a component of Hippo signaling, and dysregulation of the pathway, thereby promoting cell proliferation and resistance to apoptosis. However, the role of H.pylori-mediated YAP/TAZ has not yet been fully investigated. Our study aimed to investigate the role of YAP/TAZ in H.pylori-mediated Hippo pathway dysregulation in gastric carcinogenesis using H.pylori-infected gastric cancer cell lines, knockout mice, and patient-derived organoids. CagA-mediated YAP overexpression in gastric epithelial cells induced intestinal epithelial metaplasia and induced intracellular rearrangement of the binding protein ZO1, thereby conferring cell motility.
