Abstract
As modern medicine began to emerge at the turn of the 20th century, glycan-based therapies advanced. DNA- and protein-centered therapies became widely available. The research and development of structurally defined carbohydrates have led to new tools and methods that have sparked interest in the therapeutic applications of glycans. One of the latest omics disciplines to emerge in the contemporary post-genomics age is glycomics. In addition, to providing hope for patients and people with different health conditions through a deeper understanding of the mechanisms of common complex diseases, this new specialty in system sciences has much to offer to communities involved in the development of diagnostics and therapeutics in medicine and life sciences.This review focuses on recent developments that have pushed glycan-based therapies into the spotlight in medicine and the technologies powering these initiatives, which we can take as the most significant success of the 21st century.

Abstract
The quantification of potentially allergenic carbohydrate motifs of plant and insect glycoproteins is increasingly important in biotechnological and agricultural applications as a result of the use of insect cell-based expression systems and transgenic plants. The need to analyze N-glycan moieties in a highly parallel manner inspired us to develop a quick N-glycan analysis method based on a recently discovered bacterial protein N-glycanase (PNGase H(+)). In contrast to the traditionally used PNGase A, which is isolated from almond seeds and only releases N-glycans from proteolytically derived glycopeptides, the herein implemented PNGase H(+) allows for the release of N-glycans directly from the glycoprotein samples. Because PNGase H(+) is highly active under acidic conditions, the consecutive fluorescence labeling step using 2-aminobenzamide (2AB) can be directly performed in the same mixture used for the enzymatic deglycosylation step. All sample handling and incubation steps can be performed in less than 4 h and are compatible with microwell-plate sampling, without the need for tedious centrifugation, precipitation, or sample-transfer steps. The versatility of this methodology was evaluated by analyzing glycoproteins derived from various plant sources using ultra-performance liquid chromatography (UPLC) analysis and further demonstrated through the activity analysis of four PNGase H(+) mutant variants.

A HPLC-based glycoanalytical protocol allows the use of natural O-glycans derived from glycoproteins as substrates for glycosidase discovery from microbial culture. Glycoconj J 2013; 30:791-800. [PMID: 23793847 DOI: 10.1007/s10719-013-9483-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2013] [Revised: 05/31/2013] [Accepted: 06/04/2013] [Indexed: 10/26/2022]
Abstract
Many disorders are characterised by changes in O-glycosylation, but analysis of O-glycosylation has been limited by the availability of specific endo- and exo-glycosidases. As a result chemical methods are employed. However, these may give rise to glycan degradation, so therefore novel O-glycosidases are needed. Artificial substrates do not always identify every glycosidase activity present in an extract. To overcome this, an HPLC-based protocol for glycosidase identification from microbial culture was developed using natural O-glycans and O-glycosylated glycoproteins (porcine stomach mucin and fetuin) as substrates. O-glycans were released by ammonia-based β-elimination for use as substrates, and the bacterial culture supernatants were subjected to ultrafiltration to separate the proteins from glycans and low molecular size molecules. Two bacterial cultures, the psychrotroph Arthrobacter C1-1 and a Corynebacterium isolate, were examined as potential sources of novel glycosidases. Arthrobacter C1-1 culture contained a β-galactosidase and N-acetyl-β-glucosaminidase when assayed using 4-methylumbelliferyl substrates, but when defucosylated O-glycans from porcine stomach mucin were used as substrate, the extract did not cleave β-linked galactose or N-acetylglucosamine. Sialidase activity was identified in Corynebacterium culture supernatant, which hydrolysed sialic acid from fetuin glycans. When both culture supernatants were assayed using the glycoproteins as substrate, neither contained endoglycosidase activity. This method may be applied to investigate a microbial or other extract for glycosidase activity, and has potential for scale-up on high-throughput platforms.

Abstract
Human milk oligosaccharides (HMO) are discussed to play a crucial role in an infant's development. Lewis blood group epitopes, in particular, seem to remarkably contribute to the beneficial effects of HMO. In this regard, large-scale functional human studies could provide evidence of the variety of results from in vitro investigations, although increasing the amount and complexity of sample and data handling. Therefore, reliable screening approaches are needed. To predict the oligosaccharide pattern in milk, the routine serological Lewis blood group typing of blood samples can be applied due to the close relationship between the biosynthesis of HMO and the Lewis antigens on erythrocytes. However, the actual HMO profile of the individual samples does not necessarily correspond to the serological determinations. This review demonstrates the capabilities of merging the traditional serological Lewis blood group typing with the additional information provided by the comprehensive elucidation of individual HMO patterns by means of state-of-the-art analytics. Deduced from the association of the suggested HMO biosynthesis with the Lewis blood group, the matrix-assisted laser desorption/ionization time-of-flight mass spectrometry profiles of oligosaccharides in individual milk samples exemplify the advantages and the limitations of sample assignment to distinct groups.

Abstract
The EUROCarbDB project is a design study for a technical framework, which provides sophisticated, freely accessible, open-source informatics tools and databases to support glycobiology and glycomic research. EUROCarbDB is a relational database containing glycan structures, their biological context and, when available, primary and interpreted analytical data from high-performance liquid chromatography, mass spectrometry and nuclear magnetic resonance experiments. Database content can be accessed via a web-based user interface. The database is complemented by a suite of glycoinformatics tools, specifically designed to assist the elucidation and submission of glycan structure and experimental data when used in conjunction with contemporary carbohydrate research workflows. All software tools and source code are licensed under the terms of the Lesser General Public License, and publicly contributed structures and data are freely accessible. The public test version of the web interface to the EUROCarbDB can be found at http://www.ebi.ac.uk/eurocarb.
