Regenerating gene (REG) product and its potential clinical usage

Area of Science:

• Regenerative medicine
• Immunology
• Oncology

Background:

• The regenerating gene (Reg) family proteins function as growth factors.
• Autoimmunity against Reg proteins is linked to various diseases.
• Reg family genes are expressed in numerous cancers, affecting prognosis.

Purpose of the Study:

• To review the structure, function, and expression of Reg family genes/proteins.
• To discuss the physiological and pathological significance of Reg family genes/proteins.
• To explore the diagnostic and therapeutic potential of Reg family genes/proteins.

Main Methods:

• Literature review of Reg gene family structure, function, and expression.
• Analysis of Reg protein roles in physiological and pathological conditions.
• Discussion of diagnostic and therapeutic implications.

Main Results:

• Autoimmunity against Reg proteins may serve as a diagnostic marker for immune-mediated diseases.
• Reg proteins show potential for treating diabetes by expanding beta-cell mass.
• Overexpression of Reg genes in cancer cells enhances proliferation and provides a growth advantage.

Conclusions:

• Reg family proteins represent potential diagnostic markers and therapeutic targets for immune-mediated diseases.
• Reg proteins offer a dual approach for diabetes treatment: beta-cell expansion and autoimmunity abrogation.
• Reg genes/proteins are promising prognostic markers and therapeutic targets in oncology due to their role in cancer cell proliferation.
