Comprehensive structural glycomic characterization of the glycocalyxes of cells and tissues
The glycocalyx consists glycosylation of proteins and lipids and fcorms outermost layer of cells. It is involved in the process of inter- and intracellular fundamentals, including non-self cells and self-recognition, cell signaling, cell structure maintenance, and protective immunity. Characterization glycocalyx is therefore important to understand the physiology of the cell and elucidating its role in promoting health and disease. This protocol describes how to comprehensively characterize glycocalyx N-glycans and O-glycans of glycoproteins and glycolipids intact in parallel, using the same enriched membrane fraction.
Profile of glycans and glycolipids performed using nanoflow liquid chromatography-mass spectrometry (nanoLC-MS). Sample preparation, quantitative LC-tandem MS (LC-MS / MS) analysis, and data processing method is provided. In addition, we discuss the results of the analysis glycoproteomic that specific glycosylation of membrane proteins. To reduce the number of samples required, the N-glycan, O-glycan and glycolipid analysis performed on the same enriched fraction, whereas glycoproteomic analysis performed on a separate enriched fraction. Sample preparation process takes 2-3 d, while the time spent on instrumental analysis and data that can vary from 1 to 5 d for different sample sizes.
This workflow applies to both cell and tissue samples. systematic changes in the glycocalyx associated with certain glycoforms and glycoconjugates can be monitored by quantitation using this protocol. The ability to quantitate individual glycoforms and glycoconjugates will find utility in a variety of basic and applied clinical studies, including glycan-based biomarker discovery and therapy. congenital disorders of glycosylation (CDG) is caused by a defect in a gene that regulates various glycoconjugate biosynthesis. Some of the genes responsible have been identified in the process of N-glycosylation of proteins.
Analysis of mucin-type core-1 O-glycoforms of apolipoprotein C-III (apoCIII) has recently been revealed combined N- and O-glycosylation defects. We apply the matrix-assisted laser desorption / ionization mass spectrometry profile of glycoforms apoCIII 500 serum samples for screening CDG, and the reference values are determined.The contents apoCIII unglycosylated lower in early infancy, showed that the O-glycan occupancy should be judged based reference values of the same age.

An important function of glycans in Human Skin Model epithelium dissected by CRISPR-Cas9-Engineered Human Organotypic
glycome change characteristics during histogenesis and organogenesis, but our understanding of the importance of glycan structures selected for tissue formation and homeostasis incomplete.
Here, we present a human Organotypic platform that enables the genetic dissection of cellular glycosylation capacity and interrogation of the role of different types of glycans in tissue formation. We use CRISPR-Cas9 gene targeting to generate a 3D library of tissue selective skin Organotypic differ in their capacity to generate glycan structures on the main types of N- and O-linked glycoproteins and glycolipids.

This network library revealed different changes in skin formation associated with the loss of features for all glycoconjugates tested. Organotypic skin models provide phenotypic cues for different functions of glycoconjugates and serves as a unique resource for further genetic dissection and identification of certain structural features involved. This strategy also applies to other Organotypic network model.
