Novel Insight Into Glycosaminoglycan Biosynthesis Based on Gene Expression Profiles
Glycosaminoglycans (GAGs) including chondroitin sulfate, dermatan sulfate, heparan sulfate, and keratan sulfate, except for hyaluronan that is a free polysaccharide, are covalently attached to core proteins to form proteoglycans.

Hallmarks of glycogene expression and glycosylation pathways in squamous and adenocarcinoma cervical cancer [PDF]
Background Dysregulation of glycogene expression in cancer can lead to aberrant glycan expression, which can promote tumorigenesis. Cervical cancer (CC) displays an increased expression of glycogenes involved in sialylation and sialylated glycans.

Dermatan Sulfate-Free Mice Display Embryological Defects and Are Neonatal Lethal Despite Normal Lymphoid and Non-Lymphoid Organogenesis. [PDF]
The epimerization of glucuronic acid into iduronic acid adds structural variability to chondroitin/dermatan sulfate polysaccharides. Iduronic acid-containing domains play essential roles in processes such as coagulation, chemokine and morphogen ...

Studies on the biosynthesis of dermatan sulfate [PDF]
It is generally accepted that the biosynthesis of polysaccharide proteins in mammalian tissues follows a certain schedule [ 1,2] involving four principal steps: (a) formation of the polypeptide backbone, (b) stepwise addition of monosaccharide units from the appropiate nucleotide sugars to form the linkage j e ion to protein, and (c) the alternate ...

Two Dermatan Sulfate Epimerases Form Iduronic Acid Domains in Dermatan Sulfate [PDF]
A second dermatan sulfate epimerase (DS-epi2) was identified as a homolog of the first epimerase (DS-epi1), which was previously described by our group. DS-epi2 is 1,222 amino acids long and has an approximately 700-amino acid N-terminal epimerase domain that is highly conserved between the two enzymes.

DSE promotes aggressive glioma cell phenotypes by enhancing HB-EGF/ErbB signaling. [PDF]
Remodeling of the extracellular matrix (ECM) in the tumor microenvironment promotes glioma progression. Chondroitin sulfate (CS) proteoglycans appear in the ECM and on the cell surface, and can be catalyzed by dermatan sulfate epimerase to form ...

Biosynthesis of Dermatan Sulfate [PDF]
We identified the gene encoding chondroitin-glucuronate C5-epimerase (EC 5.1.3.19) that converts d-glucuronic acid to l-iduronic acid residues in dermatan sulfate biosynthesis. The enzyme was solubilized from bovine spleen, and an ∼43,000-fold purified preparation containing a major 89-kDa candidate component was subjected to mass spectrometry analysis

Effect of epithelial debridement on human cornea proteoglycans
Corneal transparency is attributed to the regular spacing and diameter of collagen fibrils, and proteoglycans may play a role in fibrillogenesis and matrix assembly. Corneal scar tissue is opaque and this opacity is explained by decreased ultrastructural

Impaired proteoglycan glycosylation, elevated TGF-β signaling, and abnormal osteoblast differentiation as the basis for bone fragility in a mouse model for gerodermia osteodysplastica. [PDF]
Gerodermia osteodysplastica (GO) is characterized by skin laxity and early-onset osteoporosis. GORAB, the responsible disease gene, encodes a small Golgi protein of poorly characterized function.
