  • Title: Molecular Pathogenesis of Helicobacter pylori-Related Gastric Cancer.
    Author: Shimizu T, Marusawa H, Watanabe N, Chiba T.
    Journal: Gastroenterol Clin North Am; 2015 Sep; 44(3):625-38. PubMed ID: 26314672.
    Abstract:
    Helicobacter pylori infection plays a crucial role in gastric carcinogenesis. H pylori exerts oncogenic effects on gastric mucosa through complex interaction between bacterial virulence factors and host inflammatory responses. On the other hand, gastric cancer develops via stepwise accumulation of genetic and epigenetic alterations in H pylori-infected gastric mucosa. Recent comprehensive analyses of gastric cancer genomes indicate a multistep process of genetic alterations as well as possible molecular mechanisms of gastric carcinogenesis. Both genetic processes of gastric cancer development and molecular oncogenic pathways related to H pylori infection are important to completely understand the pathogenesis of H pylori-related gastric cancer.
