Epithelial continuity depends on a family of small, yet abundant, secreted proteins the TFFs (Trefoil Factors). TFFs are considered as 'Rapid Response' agents to mucosal injury; with up-regulation of expression in the early stages of mucosal repair. These peptides are involved in mucosal maintenance and repair through motogenic and anti-apoptotic activities. They also function as scatter factors, pro-invasive and angiogenic agents. TFFs are connected with multiple oncogenic pathways. As a consequence, the TFF signalin...
