Abstract:
Rheumatoid arthritis(RA)is associated with increased bone turnover and early bone loss, which lead to increased fracture risk and progressive joint destruction. Pro-inflammatory cytokines, such as IL(interleukin)-17, TNF-α(tumor necrosis factor alpha), IL-1, and IL-6 induce the expression of RANKL(receptor activation of nuclear factor κB ligand)from synovial fibroblasts. RANKL promotes osteoclasts differentiation and activation, and Denosumab, an anti-RANKL monoclonal antibody, inhibits both systemic bone loss and focal bone erosion of RA.

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...
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...
