Gut hormones and bone homeostasis: potential therapeutic implications

Area of Science:

• Endocrinology
• Bone Physiology
• Gastroenterology

Background:

• Bone resorption exhibits a circadian rhythm, decreasing after meals.
• Gut hormones, including glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide 1 (GLP1), and GLP2, are implicated in this postprandial reduction.
• These hormones, secreted by enteroendocrine cells, influence various physiological processes.

Purpose of the Study:

• To review the evidence on how gut hormones affect bone homeostasis and physiology.
• To highlight the therapeutic potential of gut hormone analogues for bone health.

Main Methods:

• Literature review of preclinical and clinical studies.
• Analysis of research on gut hormone secretion and action.
• Examination of therapeutic strategies involving gut hormone analogues.

Main Results:

• Gut hormones play a significant role in regulating bone resorption.
• GLP1, GIP, and GLP2 analogues show promise for treating bone fragility disorders.
• Dual GIP-GLP2 analogues demonstrate therapeutic potential, impacting bone material properties.

Conclusions:

• Gut hormones are key regulators of bone homeostasis.
• Targeting gut hormone pathways offers novel therapeutic avenues for bone fragility.
• Further research into dual analogues could advance bone health treatments.
