Core Tip: Gastric cancer (GC) remains a major global health issue closely linked to Helicobacter pylori (H. pylori) infection, which induces chronic inflammation, oxidative DNA damage, and disrupts cell cycle regulation. Cytotoxin-associated gene A plays a significant role in carcinogenesis. Deleted in malignant brain tumors 1 (DMBT1), a potential tumor suppressor, shows variable expression in GC, often being downregulated in well-differentiated adenocarcinomas and upregulated in other subtypes. DMBT1 interacts directly with H. pylori to modulate the immune response. Preserved DMBT1 expression may protect against gastric carcinogenesis, whereas its downregulation may facilitate tumor progression. Understanding the DMBT1-H. pylori interaction could help identify new therapeutic strategies for the prevention and treatment of GC.
