Abstract:
Growing evidence suggests that positive association between fat mass and bone mineral density (BMD) is mediated not only biomechanical but also biochemical factors. Recent studies on adipocyte function have revealed that adipose tissue is not merely an energy-storing organ but it secretes a variety of biological active molecules, conceptualized as "adipocytokines", including leptin and adiponectin. Adipocyte also exist in bone marrow, and experimental finding indicate the dynamic involvement of adipocytokines in bone metabolism. This report aims to review some of the effects of adipocytokines in bone metabolism, in relation to visceral fat accumulation.

Hormones and Bone Tissue
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...
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...
