Area of Science:

  • Gastroenterology
  • Oncology
  • Endocrinology

Background:

  • Trefoil factor family (TFF) domain peptides are a recently identified peptide family.
  • They are primarily synthesized in the gastrointestinal tract and associated with mucin-secreting epithelial cells.
  • TFF peptides play roles in mucosal defense and healing, with a potential tumor suppressor function.

Purpose of the Study:

  • To review the expanding data on TFF peptides.
  • To summarize their role in epithelial inflammation, repair, and neoplasia.
  • To highlight their presence outside the GI tract and in various carcinomas.

Main Methods:

  • Literature review of studies on TFF peptides.
  • Analysis of TFF peptide expression in normal and cancerous tissues.
  • Examination of TFF peptide roles in inflammation, repair, and cancer.

Main Results:

  • TFF peptides are found in the hypothalamus, pituitary, and estrogen-responsive breast tissue.
  • Expression of TFF peptides is observed in urological, gynecological, gastrointestinal, pulmonary, and breast carcinomas.
  • TFF peptide expression shows prognostic significance in pulmonary and breast cancers.

Conclusions:

  • TFF peptides are involved in epithelial homeostasis and disease.
  • Their roles in inflammation, repair, and cancer warrant further investigation.
  • TFF peptides represent a promising area for cancer research and potential therapeutic targets.
