Regulation of αKlotho

Area of Science:

• Endocrinology
• Mineral Metabolism
• Aging Research

Background:

• Alpha-Klotho (αKlotho) is a protein with significant anti-aging and health-promoting properties.
• It functions as a membrane-bound cofactor for FGF23 or as a soluble hormone-like factor.
• Its role in regulating phosphate and vitamin D metabolism is crucial for overall health.

Purpose of the Study:

• To comprehensively review the regulation and function of αKlotho.
• To highlight its central role in maintaining mineral metabolism.
• To explore its therapeutic potential in age-related and chronic diseases.

Main Methods:

• Literature review of studies on αKlotho and FGF23 signaling.
• Analysis of the role of αKlotho in mineral metabolism and age-related diseases.
• Examination of the αKlotho-FGF23 axis in chronic kidney disease (CKD) and cardiovascular diseases (CVD).

Main Results:

• The αKlotho-FGF23 axis regulates renal phosphate and vitamin D metabolism.
• Disruptions in this axis are associated with deranged mineral metabolism and are early biomarkers for CKD and CVD.
• Decreased αKlotho and increased FGF23 contribute to CKD progression and associated complications like left ventricular hypertrophy (LVH).

Conclusions:

• αKlotho plays a vital role in maintaining mineral homeostasis.
• Dysregulation of the αKlotho-FGF23 axis is implicated in the pathophysiology of aging and chronic diseases.
• Targeting αKlotho may offer therapeutic strategies for age-related conditions and chronic diseases.
