Background InformationTrefoil factor 2 (UniProt: Q03404; also known as Spasmolytic polypeptide, TFF2) is encoded by the Tff2 (also known as Sml1, Sp) gene (Gene ID: 21785) in murine species. TFF2 is secreted into the mucus layer of the gastrointestinal tract of mammals where it stabilizes the mucin gel layer and stimulates migration of epithelial cells. It inhibits gastrointestinal motility and gastric acid secretion and possibly stabilizes glycoproteins in the mucus gel through interactions with carbohydrate side chains. It is also reported to stimulate epithelial restitution and restrain any associated inflammation. TFF2 levels are elevated in hypergastrinemic transgenic mice and reduced in gastrin-deficient mice. Gastrin treatment is shown to increase TFF2 promoter activity through cis-acting regions, containing CCAATA- and GC-rich enhancers. Pretreatment with gastrin/CCKB receptor antagonists is reported to abolish gastrin-dependent promoter activity. Inhibitor of PKC, MEK1, and PI-3 kinase are also shown to reduce gastrin-dependent TFF2 promoter activity. TFF2 levels are elevated in several pathological conditions, including gastric ulceration, duodenal ulceration, and Crohn s disease. In addition to its cytoprotective role, TFF2 also plays a role in the regulation of host immunity as evidenced by reduced inflammation in rat and mouse models of colitis following administration of recombinant TFF2. Higher expression of TFF2 is also observed in large tumors of the diffuse type. An increased prevalence of TFF2 expression is seen in tumors with advanced T and N stage and in patients with lymphatic and venous invasion. (Ref.: Dubeykovskaya, Z., et al. (2009). J. Biol.
