A Glycosaminoglycan Extract from Portunus pelagicus Inhibits BACE1, the β Secretase Implicated in Alzheimer’s Disease

open access: yesMarine Drugs, 2019
Therapeutic options for Alzheimer’s disease, the most common form of dementia, are currently restricted to palliative treatments. The glycosaminoglycan heparin, widely used as a clinical anticoagulant, has previously been shown to inhibit the ...

Identification of Phosphatase That Dephosphorylates Xylose in the Glycosaminoglycan-Protein Linkage Region of Proteoglycans*

open access: yesJournal of Biological Chemistry, 2014
Background: The enzyme responsible for the dephosphorylation of xylose in glycosaminoglycans remains unknown. Results: A protein that removed the phosphate from the phosphorylated linkage trisaccharide and localized in the Golgi was identified ...

Regulation of proBACE1 by Glycosaminoglycans [PDF]

open access: yesNeurodegenerative Diseases, 2008
The β-secretase (BACE1) is initially synthesized as a partially active zymogen containing a prodomain which can be further activated through proteolytic cleavage of the prodomain by a furin-like protease. The active site of BACE1 is large and although a number of high-affinity active-site inhibitors of BACE1 have been described, most of these compounds

Glycosaminoglycans in patellar cartilage [PDF]

open access: yesActa Orthopaedica Scandinavica, 1989
We obtained samples of patellar cartilage at the time of surgery from 20 patients: 11 with normal and 9 with macroscopic cartilaginous degeneration. The glycosaminoglycans were separated by cellulose acetate electrophoresis, and the relative content of major glycosaminoglycans was measured by optic scanning.

Sulfated Glycosaminoglycans as Viral Decoy Receptors for Human Adenovirus Type 37

open access: yesViruses, 2019
Glycans on plasma membranes and in secretions play important roles in infection by many viruses. Species D human adenovirus type 37 (HAdV-D37) is a major cause of epidemic keratoconjunctivitis (EKC) and infects target cells by interacting with sialic ...

Establishment of Glycosaminoglycan Assays for Mucopolysaccharidoses

open access: yesMetabolites, 2014
Mucopolysaccharidoses (MPS) are a group of lysosomal storage disorders caused by deficiency of the lysosomal enzymes essential for catabolism of glycosaminoglycans (GAGs).

Retinal Proteoglycans Act as Cellular Receptors for Basement Membrane Assembly to Control Astrocyte Migration and Angiogenesis

open access: yesCell Reports, 2016
The basement membrane is crucial for cell polarity, adhesion, and motility, but how it is assembled on the cell surface remains unclear. Here, we find that ablation of glycosaminoglycan (GAG) side chains of proteoglycans in the neuroretina disrupts the ...

A Tunable Glycosaminoglycan–Peptide Nanoparticle Platform for the Protection of Therapeutic Peptides

open access: yesPharmaceutics
The popularity of Glycosaminoglycans (GAGs) in drug delivery systems has grown as their innate ability to sequester and release charged molecules makes them adept in the controlled release of therapeutics.

Galactosaminoglycans from normal myometrium and leiomyoma

open access: yesBrazilian Journal of Medical and Biological Research, 2001
In many tumors, the amount of chondroitin sulfate in the extracellular matrix has been shown to be elevated when compared to the corresponding normal tissue. Nevertheless, the degree of chondroitin sulfate increase varies widely.
