Epithelial Repair Mechanisms

  • Biliary Epithelial Cells (BECs): TFF3 expression in BECs is STAT3-dependent and enhances wound healing by promoting migration. IL-6-deficient BECs show reduced TFF3 and impaired repair, reversible with recombinant TFF3 .

  • Signaling Pathways: STAT3 activation increases TFF3, while MAPK inhibitors (e.g., PD98059) further elevate TFF3, suggesting therapeutic potential in biliary strictures .

Clinical Relevance in Cancer

  • Breast Cancer: Serum TFF3 levels are elevated in breast cancer patients (AUC = 0.72 vs. controls). Immunohistochemistry using TFF3 antibodies shows 73.9% positivity in tumors, correlating with serum levels .

  • Therapeutic Target: Recombinant TFF3 or analogs may prevent strictures in liver grafts by enhancing epithelial repair .

Limitations and Considerations

  • Cross-Reactivity: May detect TFF3 isoforms or homologs without proper validation .

  • Sample Handling: Requires fresh or optimally stored samples to avoid protein degradation .

Target Background

Function
TFF3 plays a crucial role in maintaining and repairing the intestinal mucosa. It functions as a motogen, promoting the mobility of epithelial cells during healing processes.
