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 Tissue01:17

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
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...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a superfamily...
Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
Bone Remodeling01:40

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
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...
