Abstract:
Metabolic bone disorder is usually caused by abnormalities of minerals and hormones metabolism. Recently, it has been proved by several studies that the renin-angiotensin system (RAS) in local bone tissue is directly involved in bone metabolism. Activation of skeletal RAS plays an important role in bone metabolic disorders. Based on in vitro, in vivo, and clinical studies, this review explains the roles of RAS in bone metabolism and also covers the potential approaches and beneficial effects of RAS inhibition on bone health. Differential strategies for inhibiting RAS can be employed to maintain bone health, which are attributed primarily to the reduced level of angiotensin II (AngII) and suppressed stimulation of the AngII signaling pathway. The use of renin inhibitors, angiotensin-converting enzyme inhibitors, and AngII receptor blockers either individually or in combination with each other could have promising results in fighting bone metabolic disorders associated with other cardiovascular diseases as well as independent bone injuries.
Insights
The renin-angiotensin system (RAS) in bone tissue significantly impacts bone metabolism. Inhibiting RAS shows promise for treating metabolic bone disorders and improving bone health.
Area of Science:
- Biochemistry
- Endocrinology
- Bone Biology
Background:
- Metabolic bone disorders stem from mineral and hormonal imbalances.
- The local renin-angiotensin system (RAS) in bone is increasingly recognized for its role in bone metabolism.
- Skeletal RAS activation contributes to the pathogenesis of bone metabolic disorders.
Purpose of the Study:
- To review the multifaceted roles of the renin-angiotensin system (RAS) in regulating bone metabolism.
- To explore therapeutic strategies involving RAS inhibition for enhancing bone health.
- To discuss the clinical implications of targeting RAS for bone disorders.
Main Methods:
- Review of in vitro, in vivo, and clinical studies.
- Analysis of the molecular mechanisms underlying RAS involvement in bone.
- Evaluation of the efficacy of RAS inhibition strategies.
Main Results:
- Skeletal RAS activation is a key factor in metabolic bone disorders.
- Inhibition of RAS, primarily by reducing angiotensin II (AngII) levels and signaling, improves bone health.
- Various RAS inhibitors (renin inhibitors, ACE inhibitors, ARBs) demonstrate potential benefits.
Conclusions:
- Targeting the renin-angiotensin system offers a promising therapeutic avenue for metabolic bone disorders.
- RAS inhibition can be beneficial for bone health, both independently and in conjunction with cardiovascular disease treatment.
- Understanding skeletal RAS pathways is crucial for developing novel bone-protective strategies.

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...

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...
