Insights

Osteoporosis and cardiovascular disease share links beyond aging, potentially mediated by the osteoprotegerin (OPG)/RANK/RANKL system. This system

Area of Science:

  • Biomedical Science
  • Gerontology
  • Cardiovascular Research

Background:

  • Osteoporosis and atherosclerosis are common age-related degenerative diseases.
  • Recent research suggests a link between osteoporosis and cardiovascular diseases beyond aging.
  • The osteoprotegerin (OPG)/receptor activator of nuclear factor-kB (RANK)/RANK ligand (RANKL) system is implicated in arterial calcification.

Purpose of the Study:

  • To review recent findings on the relationship between osteoporosis and OPG/RANK/RANKL-mediated vascular disease.
  • To explore the role of the OPG/RANK/RANKL system in vascular biology.
  • To discuss the potential of OPG as a marker for vascular disease.

Main Methods:

  • Literature review of recent studies.
  • Analysis of research on the OPG/RANK/RANKL system in skeletal and vascular biology.
  • Synthesis of findings on the association between osteoporosis and vascular calcification.

Main Results:

  • The OPG/RANK/RANKL system is a potential mediator linking osteoporosis and vascular diseases.
  • OPG may function as an autocrine/paracrine regulator of vascular calcification.
  • The precise role of OPG/RANKL/RANK in vascular calcification requires further investigation.

Conclusions:

  • The OPG/RANK/RANKL system offers a potential common pathway for osteoporosis and vascular diseases.
  • Further research is needed to fully elucidate the role of this system in vascular calcification.
  • OPG may serve as a valuable serum marker for vascular disease detection.

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.
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...
Role of Vitamins in Maintaining Bone Health01:25

Role of Vitamins in Maintaining Bone Health

The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
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...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
