Description générale

proteoglycan consisting of a 45 kDa core protein and two chrondroitin/dermatan sulfate glycosaminoglycan chains

Actions biochimiques/physiologiques

Biglycan interacts with collagen type I and II, fibronectin and TGF-ß. In a low ionic strength (less than 3 mM phosphate) buffer, Biglycan binds more strongly to collagen type I. At higher ionic strengths, Biglycan will instead increase the inhibition effect of TGF-ß on osteoclast proliferation at a concentration of 4-20 mg/mL. It also functions to prevent the attachment of CHO cells to fibronectin, with a 50% inhibition at 17-21 mg/mL. As an extracellular component, Biglycan binds TGF-β 1, facilitates bone mineralization and supports osteoblast differentiation thru BMP-4 binding.

Composants

Biglycan is a 200-350 kDa proteoglycan consisting of a 45 kDa core protein and two chondroitin/dermatan sulfate glycosaminoglycan chains.

Attention

Store this product at -20°C. Stored as supplied, this powder shows little decomposition in 3 years when stored properly.

Notes préparatoires

This product is extracted from articular cartilage, chematographically purified, dialyzed against water, and 0.2 μm filtered prior to lyophilization. Once lyophilized, this powder is essentially salt-free. The product is soluble in water at 2 mg/mL.

In chondrocytes isolated directly from human articular cartilage, without subsequent culture, biglycan mRNA levels decreased with the age of the donor, whereas those for decorin increased. In cultured chondrocytes in the presence of FCS, mRNA levels for biglycan remained similar

Binding of proteoglycans to type I collagen in vitro was assessed using radiolabeled decorin, biglycan, and large proteoglycans and acid-extracted bovine tendon collagen. Decorin, biglycan, and large proteoglycans were all bound to collagen fibrils in phosphate-buffered saline (PBS) containing 3

The small proteoglycan decorin is known to interact with type I collagen fibrils, thereby influencing the kinetics of fibril formation and the distance between adjacent collagen fibrils. The structurally related proteoglycan biglycan has been proposed not to bind to fibrillar

Biglycan (bgn) is a small leucine-rich proteoglycan enriched in extracellular matrices of skeletal tissues. Bgn-deficient mice develop age-related osteopenia with a phenotype that resembles osteoporosis and premature arthritis. In the present study, we have examined the differentiation of bgn-deficient osteoblasts

The BMP4 signaling pathway plays key roles during early embryonic development and for maintenance of adult homeostasis. In the extracellular space, BMP4 activity is regulated by a group of interacting molecules including the BMP antagonist Chordin, the metalloproteinase Tolloid and

Glycosaminoglycans and Proteoglycans

There are five identified glycosaminoglycan chains (see Figure 1): Hyaluronan is not sulfated, but the other glycosaminoglycan chains contain sulfate substituents at various positions of the chain.

Glycosaminoglycan Sulfation and Signaling

Glycosaminoglycans are large linear polysaccharides constructed of repeating disaccharide units.
