Biglycan and decorin differentially regulate signaling in the fetal membranes

WISP-1 binds to decorin and biglycan.

Wnt-1-induced secreted protein 1 (WISP-1) is a member of the CCN (connective tissue growth factor, Cyr61, NOV) family of growth factors. Structural and experimental evidence suggests that CCN family member activities are modulated by their interaction with sulfated glycoconjugates. To elucidate the mechanism of action for WISP-1, we characterized the specificity of its tissue and cellular inter...

Proteoglycans Decorin and Biglycan with Interactions of the Extracellular Matrix

Distribution of biglycan and decorin in rat dental tissue.

Biglycan and decorin are small leucine-rich proteoglycans that play several biological and structural roles in different tissues and organs. Several reports have indicated that biglycan participates in odontoblast and ameloblast differentiation and in the calcification process. In the present study we show that the expression of biglycan changes from within the ameloblasts and odontoblasts to t...

Catabolism of aggrecan, decorin and biglycan in tendon.

We have examined the catabolism of the proteoglycans aggrecan, decorin and biglycan in fresh tendon samples and in explant cultures of tissue from the tensional and compressed regions of young and mature bovine tendons. A panel of well-characterized antibodies that recognize glycosaminoglycan or protein (linear or neoepitope) sequences was used to detect proteoglycans and proteoglycan degradati...

Decorin and biglycan of normal and pathologic human corneas.

PURPOSE Corneas with scars and certain chronic pathologic conditions contain highly sulfated dermatan sulfate, but little is known of the core proteins that carry these atypical glycosaminoglycans. In this study the proteoglycan proteins attached to dermatan sulfate in normal and pathologic human corneas were examined to identify primary genes involved in the pathobiology of corneal scarring. ...
