The size and multiplicity of intestinal tumors are reduced in mice overexpressing Pla2g2a (Cormier et al., 1997)The expression of PLA2G2A is positively correlated with survival in patients with gastric adenocarcinoma (Leung et al., 2002)In Muc2−/− mice, the transgenic expression of Pla2g2a suppresses intestinal tumorigenesis (Fijneman et al., 2008). The gene discussed is MUC2; the disease is gastric adenocarcinoma.
