Abstract
BACKGROUND Mass spectrometry-based proteomics and glycomics reveal post-translational modifications providing significant biological insights beyond the scope of genomic sequencing.
AIM To characterize the N-linked glycoproteomic profile in esophageal squamous cell carcinoma (ESCC) via two complementary approaches.
METHODS Using tandem multilectin affinity chromatography for enrichment of N-linked glycoproteins, we performed N-linked glycoproteomic profiling in ESCC tissues by two-dimensional gel electrophoresis (2-DE)-based and isobaric tags for relative and absolute quantification (iTRAQ) labeling-based mass spectrometry quantitation in parallel, followed by validation of candidate glycoprotein biomarkers by Western blot.
RESULTS 2-DE-based and iTRAQ labeling-based quantitation identified 24 and 402 differentially expressed N-linked glycoproteins, respectively, with 15 in common, demonstrating the outperformance of iTRAQ labeling-based quantitation over 2-DE and complementarity of these two approaches. Proteomaps showed the distinct compositions of functional categories between proteins and glycoproteins with differential expression associated with ESCC. Western blot analysis validated the up-regulation of total procathepsin D and high-mannose procathepsin D, and the down-regulation of total haptoglobin, high-mannose clusterin, and GlcNAc/sialic acid-containing fraction of 14-3-3ζ in ESCC tissues. The serum levels of glycosylated fractions of clusterin, proline-arginine-rich end leucine-rich repeat protein, and haptoglobin in patients with ESCC were remarkably higher than those in healthy controls.
CONCLUSION Our study provides insights into the aberrant N-linked glycoproteome associated with ESCC, which will be a valuable resource for future investigations.

Abstract
The extracellular matrix of the bone and dentin contains several non-collagenous proteins (NCPs). One category of NCPs is termed the SIBLING (small integrin-binding ligand, N-linked glycoprotein) family, which includes osteopontin (OPN), bone sialoprotein (BSP), dentin matrix protein 1 (DMP1), dentin sialophosphoprotein (DSPP), etc. These proteins have abundant phosphoserines, aspartic acids, and glutamic acids. In this protocol, we describe the extraction of NCPs from the bone and dentin matrices using guanidine-HCl/EDTA and the isolation of polyanionic SIBLINGs from NCPs using ion-exchange fast protein liquid chromatography (FPLC) to separate the differentially charged proteins into different fractions through a gradient elution by NaCl.

Abstract
Group A rotaviruses (RVAs) are divided into neuraminidase (NA)-sensitive and NA-insensitive strains depending upon their binding affinity to the VP8* domain in the terminal sialic acids (SAs) of cell surface carbohydrates. Although NA-sensitive strains are known to use terminal SAs as an attachment factor, the exact nature of this attachment factor is largely unknown. Here we show that the specific linkage of SA-containing glycan to glycoprotein or glycolipid is an attachment factor used by NA-sensitive porcine G9P[7] PRG9121 and G9P[23] PRG942, bovine G6P[1] NCDV, and canine G3P[3] strains. Infectivity of porcine G9P[7] and G9P[23] strains was markedly blocked by α2,3-linkage and α2,6-linkage inhibitors, indicating that these strains bind to both α2,3- and α2,6-linked SAs. However, the infectivity of bovine G6P[1] and canine G3P[3] strains was significantly reduced by α2,6-linkage inhibitor but not by α2,3-linkage blockers, demonstrating a predilection of these strains for α2,6-linked SAs. The infectivity of four NA-sensitive strains was equally reduced by inhibitors of lipid membrane and N-linked glycoprotein but not by an inhibitor of O-linked glycoprotein, indicating that these strains utilize both glycolipid and N-linked glycoprotein. Our study demonstrates that four NA-sensitive animal strains could have a strain-dependent binding preference toward α2,6-linked SAs (P[1] NCDV and P[3] CU-1 strains) or both α2,3- and α2,6-linked SAs (P[7] PRG9121 and P[23] PRG942 strains) to the glycolipid and N-linked glycoprotein.

Abstract
Calnexin (CNX), known as a lectin chaperone located in the endoplasmic reticulum (ER), specifically recognizes G1M9GN2-proteins and facilitates their proper folding with the assistance of ERp57 in mammalian cells. However, it has been left unidentified how CNX works in Aspergillus oryzae, which is a filamentous fungus widely exploited in biotechnology. In this study, we found that a protein disulfide isomerase homolog TigA can bind with A. oryzae CNX (AoCNX), which was revealed to specifically recognize monoglucosylated glycans, similarly to CNX derived from other species, and accelerate the folding of G1M9GN2-ribonuclease (RNase) in vitro. For refolding experiments, a homogeneous monoglucosylated high-mannose-type glycoprotein G1M9GN2-RNase was chemoenzymatically synthesized from G1M9GN-oxazoline and GN-RNase. Denatured G1M9GN2-RNase was refolded with highest efficiency in the presence of both soluble form of AoCNX and TigA. TigA contains two thioredoxin domains with CGHC motif, mutation analysis of which revealed that the one in N-terminal regions is involved in binding to AoCNX, while the other in catalyzing protein refolding. The results suggested that in glycoprotein folding process of A. oryzae, TigA plays a similar role as ERp57 in mammalian cells, as a partner protein of AoCNX.
