Background Information

Trefoil factor 3 (TFF3) belongs to the TFF-domain peptide family which consists of three small secreted proteins (TFF1, TFF2, TFF3) that are expressed by mucous-secreting epithelia. TFF3 is a major constituent in the goblet cells in small and large intestines, especially a typical secretary peptide of the normal human antral and pyloric gastric mucosa. TFF3 is essential in regulating cell migration and maintaining normal GI mucosal integrity. TFF3 has been reported to be overexpressed at the gene and the protein level in human neoplasms such as prostate, breast, and colon cancer. TFF3 is involved in tumor cell scattering, angiogenesis, and invasion.
