Insights

Hyaluronan (HA) regulates vascular calcification by influencing vascular smooth muscle cell (VSMC) differentiation. Targeting HA pathways offers a novel therapeutic strategy for preventing arterial calcification and cardiovascular mortality.

Area of Science:

  • Biomedical Science
  • Cardiovascular Research
  • Cell Biology

Background:

  • Vascular calcification is a significant risk factor for cardiovascular mortality.
  • Vascular smooth muscle cell (VSMC) osteogenic differentiation drives calcification.
  • Current treatments for vascular calcification are limited.

Purpose of the Study:

  • To investigate the role of Hyaluronan (HA) in VSMC osteogenic differentiation.
  • To explore HA as a potential therapeutic target for arterial calcification.

Main Methods:

  • Human aortic VSMCs were treated with high phosphate and/or cytokines (IL6, TGF-β1).
  • Gene and protein expression of HA-related molecules and osteogenic markers were analyzed.
  • An in vivo mouse model of arterial calcification was utilized.
  • Pharmacological and genetic manipulations of HA synthesis and degradation were performed.

Main Results:

  • High phosphate/cytokine stimulation induced VSMC osteogenic differentiation, reduced HA deposition, and altered expression of HA synthases, hyaluronidases, and binding proteins.
  • Similar changes were observed in a mouse model of arterial calcification.
  • Modulating HA synthesis/degradation impacted VSMC osteogenic differentiation.

Conclusions:

  • Hyaluronan (HA) and its associated proteins are key regulators of VSMC osteogenic differentiation and arterial calcification.
  • HA represents a novel therapeutic target for treating vascular calcification.

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...
Glycosaminoglycans01:23

Glycosaminoglycans

Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long and linear polymers comprising of specific repeating disaccharides - the amino sugar that can be N-acetylglucosamine or N-acetylgalactosamine, and a uronic acid that is usually glucuronic acid or iduronic acid.
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.

Growth of Cartilage and Bone Tissue01:27

Growth of Cartilage and Bone Tissue

Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...
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...
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 Cells and Tissue01:30

Bone Cells and Tissue

Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the periosteum and...
