Summary
Klotho protein is crucial for regulating kidney electrolyte balance, including calcium, phosphate, and potassium. Its deficiency severely impacts mineral metabolism, growth, and longevity, highlighting its therapeutic potential.
Area of Science:
- Endocrinology and Nephrology
- Molecular Biology
Background:
- Klotho is a multifunctional protein integral to the fibroblast growth factor (FGF) signaling pathway.
- It plays a critical role in regulating renal electrolyte homeostasis, particularly calcium, phosphate, and potassium metabolism.
Purpose of the Study:
- To review the physiological significance of Klotho in mineral metabolism.
- To explore Klotho's role in renal pathology and vascular events.
- To discuss potential therapeutic applications of Klotho.
Main Methods:
- Comparison of various murine models with targeted renal Klotho deletions.
- Analysis of insights gained from these models regarding Klotho's molecular and physiological functions.
Main Results:
- Klotho deficiency in vivo leads to significantly impaired mineral metabolism.
- Consequences of deficiency include adverse effects on growth, longevity, and disease development.
- Klotho's involvement in renal pathology and vascular events is explored.
Conclusions:
- Klotho is essential for understanding in vivo renal molecular mechanisms of electrolyte handling.
- The review highlights novel therapeutic interventions targeting Klotho.
- Klotho research offers insights into mineral metabolism and related diseases.

The renal tubule is divided into three parts: the proximal convoluted tubule (PCT), the Loop of Henle (LOH), and the distal convoluted tubule (DCT).
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...

01:21Skeleton and Calcium Homeostasis
4.4K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

3.8K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
