Abstract:
Evolutionary consideration and clinical observations led us to hypothesize 10 yr ago that there may be a coordinated regulation, endocrine in nature, of bone remodeling and energy metabolism. The existence of this coordinated regulation is motivated by the energetic needs of the skeleton; therefore, this regulation relies on hormones that appear during evolution with the skeleton, not with energy metabolism. Leptin is such a hormone, and it is a critical regulator of bone mass as well as of appetite and energy expenditure. This review goes over the anatomical route and molecular pathways used by leptin to inhibit both bone mass accrual and appetite through its signaling in the brain.

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...
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...
