Outline of Final Research Achievements |
Intestine-specific homeobox, ISX, is a homeobox gene and express intestine specific. ISX don’t express in normal stomach and Helicobacter pylori infection induce ISX expression in stomach via NF-κB signaling. ISX expressing gastric cancer generate in the ISX expressing gastric mucosa, and ISX knockout in gastric carcinogenesis mouse model suppressed gastric carcinogenesis. ISX knockdown in ISX expressing gastric cancer suppressed intestinal metaplasia marker and gastric cancer growth. ISX expression increased in organoids cultured from Helicobacter-infected mouse and human gastric mucosa. ISX plays an important role in gastric carcinogenesis and tumor growth, indicating that ISX may become a molecular target for gastric carcinogenesis and gastric cancer.
