Alzheimer s disease and heparan sulfate proteoglycan
Frontiers in Bioscience, 1998Alzheimer's disease (AD) is a debilitating neurodegenerative disorder. Cardinal histopathologic changes of AD are neurofibrillary tangles (NFTs) and deposits of beta-amyloid protein (A-beta) in the form of neuritic plaques (NPs). Several different mutations found in patients with familial AD have been demonstrated to increase A-beta production ...

Binding of Rat Thyroglobulin to Heparan Sulfate Proteoglycans
Thyroid, 2000We previously showed that rat thyroglobulin (Tg) is a heparin-binding protein and that heparin inhibits Tg binding to megalin (gp330), an endocytic Tg receptor found on the apical surface of thyrocytes. Cooperation between cell surface receptors and heparin-like molecules, namely heparan sulfate proteoglycans (HSPGs), can facilitate cell surface ...

Development of Molecules Antagonizing Heparan Sulfate Proteoglycans
Seminars in Thrombosis and Hemostasis, 2021AbstractHeparan sulfate proteoglycans (HSPGs) occur in almost every tissue of the human body and consist of a protein core, with covalently attached glycosaminoglycan polysaccharide chains. These glycosaminoglycans are characterized by their polyanionic nature, due to sulfate and carboxyl groups, which are distributed along the chain.

Abstract Heparan sulfate proteoglycans (HSPGs)1 are highly charged macromolecules consisting of different core proteins with covalently linked heparan sulfate chains (HS) of varying monosaccharide sequence. These molecules are involved in a multitude of biologic processes including regulation of mesoderm induction, extension of neurites,

Heparan sulfate proteoglycans in Drosophila neuromuscular development
Biochimica et Biophysica Acta (BBA) - General Subjects, 2017Heparan sulfate proteoglycans (HSPGs) are glycoconjugates bearing heparan sulfate (HS) chains covalently attached to core proteins, which are ubiquitously distributed on the cell surface and in the extracellular matrix. HSPGs interact with a number of molecules mainly through HS chains, which play critical roles in diverse physiological and disease ...

Integral membrane heparan sulfate proteoglycans
The FASEB Journal, 1993Heparan sulfate is a regulatory polysaccharide. It modulates specific growth factor‐receptor interactions, accelerates the formation of specific proteinase‐proteinase inhibitor complexes, and mediates interactions of the cell surface with several enzymes and structural proteins.

Heparan sulfate proteoglycans in extravasation
Frontiers in Bioscience, 2009Heparan sulfate proteoglycans (HSPGs) are glycoconjugates that are implicated in various biological processes including development, inflammation and repair, which is based on their capacity to bind and present several proteins via their carbohydrate side chains (glycosaminoglycans; GAGs). Well-known HSPGs include the family of syndecans and glypicans,

Heparan sulfate proteoglycans in healthy and diseased systems
WIREs Systems Biology and Medicine, 2011AbstractHeparin and heparan sulfate (HS) are glycosaminoglycans (GAGs) that are synthesized in the tissues and organs of mammals. They are synthesized and attached to a core protein as proteoglycans through serine–glycine concensus motifs along the core protein.

Synthesis of heparan sulfate proteoglycans by the isolated glomerulus
Biochemistry and Cell Biology, 1988Incorporation of [35S]sulfate into newly synthesized macromolecules was studied in the isolated rat glomerulus and found to be linear between 6 and 24 h. When whole glomeruli were treated under conditions that dissociate proteoglycan aggregates, >90% of incorporated label was extracted.

Heparan Sulfate Proteoglycan-Mediated Polyamine Uptake
2011The polyamines are polycationic compounds essential for cellular proliferation and transformation. In addition to a well-defined biosynthesis pathway, polyamines are internalized into cells by as yet incompletely defined mechanisms. Numerous reports have shown that efficient polyamine uptake depends on the presence of polyanionic, cell surface ...
