Preparation of the Partially Methylated Alditol Acetates Derived from CS Tetrasaccharides Containing Galactose for the Gas Chromatography/Mass Spectrometry Analysis

open access: yesBio-Protocol, 2017
Chondroitin sulfate (CS), a member of the glycosaminoglycan (GAG) family of carbohydrates, is composed of linear, sulfated repeating disaccharide sequences of N-acetyl-D-galactosamine (GalNAc) and glucuronic acid (GlcA).

Keratan Sulfate in Neuronal Network Reconstruction

open access: yesTrends in Glycoscience and Glycotechnology, 2011
ケラタン硫酸は2糖の繰り返し構造を単位とするグリコサミノグリカンの一つであり、コアプロテインに共有結合することによりケラタン硫酸プロテオグリカンを生ずる。ケラタン硫酸プロテオグリカンは元来角膜抽出物において発見され、また関節軟骨中において豊富に見出されたため、これら組織における構造や生物学的機能が注目されてきた。しかし1980年代に入り中枢神経系においても見出され、神経系の発達や疾患における働きが注目を集めてきた。現在、ケラタン硫酸プロテオグリカンは生理的および損傷後神経可塑性を制御する主要な分子の一つとして受け入れられ始めている。

Lessons learned from surgical management of craniovertebral instability in Morquio syndrome: A series of four unusual cases

open access: yesJournal of Craniovertebral Junction and Spine, 2020
Morquio syndrome (MS) is an autosomal recessive defect caused by the deficiency of N-acetylgalactosamine-6-sulfatase. Odontoid hypoplasia, periodontoid soft tissue deposition, and cervical stenosis lead to myelopathy and quadriparesis in these patients ...

Increased migratory activity and cartilage regeneration by superficial-zone chondrocytes in enzymatically treated cartilage explants

open access: yesBMC Musculoskeletal Disorders, 2022
Background Limited chondrocyte migration and impaired cartilage-to-cartilage healing is a barrier in cartilage regenerative therapy. Collagenase treatment and delivery of a chemotactic agent may play a positive role in chondrocyte repopulation at the ...

Mucin-like glycopolymer gels in electrosensory tissues generate cues which direct electrolocation in amphibians and neuronal activation in mammals

open access: yesNeural Regeneration Research, 2019
Mucin-like glycoproteins have established roles in epithelial boundary protection and lubricative roles in some tissues. This mini-review illustrates alternative functional roles which rely on keratan sulphate and sialic acid modifications to mucin ...

GAG-DB, the New Interface of the Three-Dimensional Landscape of Glycosaminoglycans

open access: yesBiomolecules, 2020
Glycosaminoglycans (GAGs) are complex linear polysaccharides. GAG-DB is a curated database that classifies the three-dimensional features of the six mammalian GAGs (chondroitin sulfate, dermatan sulfate, heparin, heparan sulfate, hyaluronan, and keratan ...

Axonal pathfinding during the development of the nervous system

open access: yesAnnals of the Child Neurology Society, 2023
Guidance of axons sprouting from maturing neuroblasts, during intermediate trajectories and in seeking target neurons for synaptogenesis, is a fundamental developmental process in central nervous system maturation.

A review on an imperative by-product: Glycosaminoglycans- A holistic approach

open access: yesCarbohydrate Polymer Technologies and Applications, 2023
Glycosaminoglycan is a generic term for a class of minor but significant components of the body. The extraction, application, and functionalization of GAGs are essential to explore owing to their biological significance.
