Trefoil factors: Gastrointestinal-specific proteins associated with gastric cancer

Area of Science:

• Gastroenterology
• Molecular Biology
• Oncology

Background:

• Trefoil factor family (TFF) comprises TFF1, TFF2, and TFF3, secreted peptides with distinct trefoil and dimerization domains.
• TFF1 and TFF2 are implicated as gastric tumor suppressors, while TFF3 may promote gastric carcinoma.
• TFFs are crucial in digestive system regulation, including mucosal repair, cell proliferation, apoptosis, and signal transduction.

Purpose of the Study:

• To review the structural and biological characteristics of the Trefoil factor family (TFF).
• To elucidate the diverse roles of TFF peptides in the mammalian digestive system.
• To highlight the unresolved action mechanisms and potential interactions of TFFs.

Main Methods:

• Literature review of studies on TFF structure and function.
• Analysis of TFF expression patterns in different tissues.
• Examination of TFF involvement in physiological and pathological processes.

Main Results:

• TFF peptides exhibit varied roles, from tumor suppression (TFF1, TFF2) to promotion (TFF3).
• TFFs are involved in critical digestive functions like epithelial cell reconstruction and mucosal protection.
• Recent findings suggest interplay between TFF1 and gastrokines (GKNs).

Conclusions:

• TFFs are multifunctional peptides with significant roles in digestive health and disease.
• Further research is needed to fully understand TFF action mechanisms and their therapeutic potential.
• The interaction between TFFs and gastrokines warrants deeper investigation.
