Proteoglycans and Osteolysis [PDF]

open access: yes, 2011
Osteolysis is a complex mechanism resulting from an exacerbated activity of osteoclasts associated or not with a dysregulation of osteoblast metabolism leading to bone loss. This bone defect is not compensated by bone apposition or by apposition of bone matrix with poor mechanical quality.

Chondroitin Sulfate as a Potential Modulator of the Stem Cell Niche in Cornea

open access: yesFrontiers in Cell and Developmental Biology, 2021
Chondroitin sulfate (CS) is an important component of the extracellular matrix in multiple biological tissues. In cornea, the CS glycosaminoglycan (GAG) exists in hybrid form, whereby some of the repeating disaccharides are dermatan sulfate (DS).

An Overview of in vivo Functions of Chondroitin Sulfate and Dermatan Sulfate Revealed by Their Deficient Mice

open access: yesFrontiers in Cell and Developmental Biology, 2021
Chondroitin sulfate (CS), dermatan sulfate (DS) and heparan sulfate (HS) are covalently attached to specific core proteins to form proteoglycans in their biosynthetic pathways.

Evidence for the role of proteoglycans in cation-mediated gene transfer [PDF]

open access: yes, 1996
We report evidence that gene complexes, consisting of polycations and plasmid DNA enter cells via binding to membrane-associated proteoglycans. Treatment of HeLa cells with sodium chlorate, a potent inhibitor of proteoglycan sulfation, reduced luciferase

Interaction with proteoglycans enhances the sterol efflux produced by endogenous expression of macrophage apoE

open access: yesJournal of Lipid Research, 2001
Endogenous expression of apolipoprotein (apo)E in macrophages facilitates cholesterol efflux in the presence and absence of extracellular sterol acceptors. A proteoglycan-associated pool of apoE has also been described.

Increased expression of aggrecan and biglycan mRNA in Achilles tendinopathy [PDF]

open access: yes, 2006
To determine the expression of mRNA encoding the proteoglycans aggrecan, versican, biglycan and decorin in mid-tendon samples of chronic painful Achilles tendinopathy and ruptured Achilles tendons, compared with normal tendons.

A Reinterpretation of Evidence for the Endothelial Glycocalyx Filtration Structure

open access: yesFrontiers in Cell and Developmental Biology, 2021
The endothelial glycocalyx (eGlx) is thought to be the primary macromolecular filter for fluid flux out of the vasculature. This filter maintains the higher protein concentration within the vessel lumen relative to the tissue.

RNA-Seq identifies SPGs as a ventral skeletal patterning cue in sea urchins [PDF]

open access: yes, 2016
The sea urchin larval skeleton offers a simple model for formation of developmental patterns. The calcium carbonate skeleton is secreted by primary mesenchyme cells (PMCs) in response to largely unknown patterning cues expressed by the ectoderm.

Tissue-specific expression of carbohydrate sulfotransferases drives keratan sulfate biosynthesis in the notochord and otic vesicles of Xenopus embryos

open access: yesFrontiers in Cell and Developmental Biology, 2023
Keratan sulfate (KS) is a glycosaminoglycan that is enriched in vertebrate cornea, cartilage, and brain. During embryonic development, highly sulfated KS (HSKS) is first detected in the developing notochord and then in otic vesicles; therefore, HSKS has ...

Smad4 regulates growth plate matrix production and chondrocyte polarity. [PDF]

open access: yes, 2017
Smad4 is an intracellular effector of the TGFβ family that has been implicated in Myhre syndrome, a skeletal dysplasia characterized by short stature, brachydactyly and stiff joints.
