Abstract:
There are two kinds of incretin, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) . GIP directly affects osteoblasts and osteoclasts, resulting in increasing bone mass by enhancing bone formation and suppressing bone resorption. On the other hand, GLP-1 does not affect bone directly. GLP-1 is reported to stimulate calcitonin secretion in thyroid gland and then indirectly increase bone mass. Dipeptidyl peptidase-4 inhibitors, which activate the function of incretin, may decrease the risk of osteoporotic fractures. In addition, it has been shown that osteoblast-derived osteocalcin stimulates GLP-1 secretion. Therefore, there may be an interaction between bone and digestive tract.

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...
Glucagon-like Receptor Agonists
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

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...
Osteoclasts in Bone Remodeling
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...
