FunctionTFF3 belongs to a unique family of abundant GI3 peptides with a distinct 3-loop structure formed by a highly conserved motif of cysteine disulfide bonds, which confer them with remarkable luminal stability (1). They are mainly synthesized and secreted by mucin-secreting epithelial cells lining the gastrointestinal tract and have a close association with mucins. Their functions are not defined, but they may protect the mucosa from insults, stabilize the mucus layer and affect healing of the epithelium (2). TFF3 is expressed in goblet cells of the intestines and colon, and has recently been abundantly found in salivary glands (3). TFF3 expression has been detected in neoplastic human colonic mucosa, co-localizing with neutral mucin production, but loss of TFF3 expression is associated with tumor necrosis and advanced Duke's stage (4). Suppression of TFF3 mRNA expression is related to malignant characteristics of thyroid follicular cell-derived tumors and the expression level of TFF3 mRNA is the most promising indicator for diagnosing follicular carcinoma (5). TFF3 is induced in breast carcinomas in a hormone dependent manner (6).
