The phosphate regulating hormone fibroblast growth factor-23

Area of Science:

• Biochemistry
• Genetics
• Endocrinology

Background:

• Phosphate (Pi) homeostasis is crucial for health, with dysregulation leading to various diseases.
• Recent advances in biochemical and genetic tools have clarified mechanisms of Pi dysregulation.
• Understanding Pi regulation is vital for treating hypo- and hyperphosphatemic conditions.

Purpose of the Study:

• To review the discovery and significance of fibroblast growth factor-23 (FGF23) in phosphate regulation.
• To explore the biochemistry, production sites, receptor interactions, and action mechanisms of FGF23.
• To consolidate current knowledge on FGF23 as a central regulator of Pi homeostasis.

Main Methods:

• Literature review of studies on FGF23 and phosphate homeostasis.
• Analysis of biochemical and genetic data related to FGF23.
• Synthesis of findings on FGF23's role in physiological and pathophysiological states.

Main Results:

• Fibroblast growth factor-23 (FGF23) has emerged as a critical hormonal regulator of phosphate (Pi) homeostasis.
• FGF23 is produced in bone and influences Pi excretion and reabsorption.
• Understanding FGF23's mechanisms provides insights into Pi dysregulation.

Conclusions:

• FGF23 is a pivotal factor in maintaining phosphate balance.
• Further research into FGF23's role can illuminate treatments for phosphate-related disorders.
• This review synthesizes key aspects of FGF23, highlighting its importance in Pi homeostasis.
