Importantly, the glycomics and glycoproteomics data unveiled that comparatively high abundance of two core-fucosylated and sialylated N-glycans (Glycan 40a and Glycan 46a) and one N-glycopeptide from fibronectin were associated with low patient survival, while a relatively low abundance of N-glycopeptides from both afamin and CD59 were also associated with poor survival.

ImpaRATOR is an O-glycan-dependent protease that digests proteins carrying mucin-type O-glycans, including sialylated species, N-terminally of glycosylated Ser and Thr residues. (genovis.com)
O-Glycoprotease (IMPa) is a broad specificity protease that cleaves the peptide bonds of a glycoprotein or glycopeptide immediately N-terminal to a serine or threonine residue containing a mucin-type O-linked glycan with or without sialylation. (neb.com)
Glycosylation refers to a sequence of events that take place in the Golgi body and the endoplasmic reticulum of the cells of the expression system (predominantly mammalian) that lead to post-translational addition and processing of carbohydrate or glycan moieties to the protein backbone (usually serine- or threonineâ linked glycosylation for O-linked glycans and asparagineâ linked glycosylation for N-linked glycans) (6).

It recognizes mucin-type O-glycans in glycoproteins or glycopeptides, including branched and sialylated structures, and cleaves the peptide bond immediately N-terminal to a glycosylated serine or threonine residue. (neb.com)
O-Glycoprotease (IMPa) cleaves a variety of glycoproteins and glycopeptides containing mucin-type O-glycans with or without sialic acid, including Tn-antigen (GalNAc-α-Ser/Thr). (neb.com)

While all tumor tissues displayed relatively uniform N-glycome profiles suggesting overall stable global N-glycosylation during disease progression, altered expression of six sialylated N-glycans was found to correlate with lymph node metastasis. (bvsalud.org)
The relative abundance of sialylated glycans in the S1 subunit compared to the full-length protein could indicate differences in the global structure and function of these two species. (cdc.gov)

O-GlcNAc (short for O-linked GlcNAc or O-linked β-N-acetylglucosamine) is a reversible enzymatic post-translational modification that is found on serine and threonine residues of nucleocytoplasmic proteins. (wikipedia.org)

Permeabilizing cells with detergent prior to radiolabeling greatly increased the amount of [3H]galactose incorporated into Galβ1-4GlcNAcitol, leading the authors to conclude that most of the O-linked GlcNAc monosaccharide residues were intracellular. (wikipedia.org)

In the current study we show that designer glycopeptides containing the Thomsen-Freidenreich (TF) antigen (β-Gal-[1→3]-α-GalNAc- O -serine) are immunogenic in vivo and generate TF-specific CTL capable of recognizing a variety of tumor cells in vitro including a MUC1-expressing tumor.

Additionally, we applied multiple digestion methods on each sample, and confirmed the results for individual glycosylation sites from different experiment conditions to improve the identification and quantification of glycopeptides. (cdc.gov)

Here we demonstrate that by using glycopeptides with high affinity for the major histocompatibility complex and glycosylated in a position corresponding to a critical T cell receptor (TcR) contact, it is possible to induce anti-TACA CTL in vivo. (silverchair.com)

Accumulated data indicate that hematopoietic stem cell transplantation may be effective under optimal conditions in preventing the progression of central nervous system symptoms in neuronopathic forms of lysosomal storage diseases (such as Krabbe disease), including some of the mucopolysaccharidoses, oligosaccharidoses, sphingolipidoses, and lipidoses as well as peroxisome disorders such as X-linked adrenoleukodystrophy.
