[Updates on rickets and osteomalacia: various roles of Klotho and FGF23 in vivo ]
1Foundation for Biomedical Research and Innovation, Japan.
Abstract:
Recent understandings of phosphate regulation have, at least in part, depended upon the findings of fibroblast growth factor (FGF) 23, the hormone specific for phosphate regulation. Moreover, FGF23 would be the most important marker for prognosis in chronic kidney disease (CKD) . On the other hand, Klotho was firstly developed as a responsible gene for senescence. Although the role of Klotho has been so far established as a co-receptor for FGF23 in mineral metabolism, Klotho would play rather various roles than FGF23 signaling. Thus Klotho is not necessarily equivalent to FGF23. Further studies for both Klotho and FGF23 will elucidate to understand mineral homeostasis.

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

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...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
