Glycomics & Glycoproteomics: From Analytics to Function
Morten Thaysen-Andersen, Daniel Kolarich and Nicolle H. Packer introduce the Molecular Omics themed issue on Glycomics & Glycoproteomics: From Analytics to Function.
Protein glycosylation in Leishmania spp.
Protein glycosylation is a co- and post-translational modification that, in Leishmania parasites, plays key roles in vector–parasite–vertebrate host interaction.
Identifying the targets and functions of N-linked protein glycosylation in Campylobacter jejuni
Virulence of Campylobacter jejuni is dependent on the ability to glycosylate membrane-associated proteins.
N-Glycosylation in isolated rat nerve terminals
Glycomics and sialiomics of isolated synaptosomes reveal distinct glycosylation of surface proteins localized in the active zone of synapses.

N-Linked glycosylation profiles of therapeutic induced senescent (TIS) triple negative breast cancer cells (TNBC) and their extracellular vesicle (EV) progeny
Therapeutic-induced-senescent (TIS) Cal51 TNBC cells display differential N-glycan moieties compared to non-senescent cells, depending on cellular location and EV progeny.
Rapid and sensitive glycan targeting by lectin-SERS assay
The fabrication of lectin-SERS nanotags and the assay designed for rapid glycoprotein identification and quantification.
Robustness in glycosylation systems: effect of modified monosaccharides, acceptor decoys and azido sugars on cellular nucleotide-sugar levels and pattern of N-linked glycosylation
Chemical perturbation studies reveal robustness in glycosylation systems, based on comparison of LC-MS/MS quantification of cellular nucleotide-sugar levels with the observed N-linked glycan patterns.

Serial in-solution digestion protocol for mass spectrometry-based glycomics and proteomics analysis
A high-throughput & efficient protocol for mass spectrometry-based glycomic and proteomic analysis.
Mycobacterium bovis BCG infection alters the macrophage N-glycome
Macrophage glycosylation that is essential to the host-immune defense may be modulated by pathogens infection.
Recombinant mucin-type proteins carrying LacdiNAc on different O-glycan core chains fail to support H. pylori binding
The β4-N-acetylgalactosaminyltransferase 3 (B4GALNT3) transfers GalNAc in a β1,4-linkage to GlcNAc forming the LacdiNAc (LDN) determinant on oligosaccharides.
β-Catenin/CBP inhibition alters epidermal growth factor receptor fucosylation status in oral squamous cell carcinoma
Genomic and structural analyses reveal that β-catenin/CBP signaling represses epidermal growth factor receptor (EGFR) N-glycan antennary fucosylation in oral cancer.
Research Article
Choosing proper normalization is essential for discovery of sparse glycan biomarkers
In this work we assess the effect of different normalization methods on variable selection in an emerging field of glycomics.
Mass spectrometric analysis of core fucosylation and sequence variation in a human–camelid monoclonal antibody
ESI-MS fucosylation studies on an intact EG2-hFc monoclonal antibody reveal the presence of fucose on both Fc N-glycans.
