Increased expression of the high-mannose M6N2 and NeuAc3H3N3M3N2F tri-antennary N-glycans in cholangiocarcinoma
Changes in protein glycosylation have been reported in various types of cancer, including cholangiocarcinoma (CCA). Nanospray ionization-linear ion trap mass spectrometry (NSI-MS n ) was used in the present study to determine the comparative structural glycomics of the N-linked glycans in the serum of patients with CCA compared with healthy controls. A total of 5 high-mannose and 4 complex N-li...
متن کاملDifferent Immunity Elicited by Recombinant H5N1 Hemagglutinin Proteins Containing Pauci-Mannose, High-Mannose, or Complex Type N-Glycans
Highly pathogenic avian influenza H5N1 viruses can result in poultry and occasionally in human mortality. A safe and effective H5N1 vaccine is urgently needed to reduce the pandemic potential. Hemagglutinin (HA), a major envelope protein accounting for approximately 80% of spikes in influenza virus, is often used as a major antigen for subunit vaccine development. In this study, we conducted a ...
متن کاملUpregulation of TCTP is associated with cholangiocarcinoma progression and metastasis
In order to investigate the role of translationally-controlled tumor protein (TCTP) in cholangiocarcinoma (CCA) progression and metastasis, TCTP protein staining in paraffin-embedded sections of human CCA tissue samples was examined using immunohistochemistry, and its expression was subsequently compared with clinicopathological parameters. Small interfering RNA (siRNA) targeting TCTP (siTCTP) ...
متن کاملGalactose-extended glycans of antibodies produced by transgenic plants.
Plant-specific N-glycosylation can represent an important limitation for the use of recombinant glycoproteins of mammalian origin produced by transgenic plants. Comparison of plant and mammalian N-glycan biosynthesis indicates that beta1,4-galactosyltransferase is the most important enzyme that is missing for conversion of typical plant N-glycans into mammalian-like N-glycans. Here, the stable ...
متن کاملSubstrate specificity analysis of endoplasmic reticulum glucosidase II using synthetic high mannose-type glycans.
Glucosidase II (Glc'ase II) is a glycan-processing enzyme that trims two alpha1,3-linked Glc residues in succession from the glycoprotein oligosaccharide Glc2Man9GlcNAc2 to give Glc1Man9GlcNAc2 and Man9GlcNAc2 in the endoplasmic reticulum (ER). Monoglucosylated glycans, such as Glc1-Man9GlcNAc2, generated by this process play a key role in glycoprotein quality control in the ER, because they ar...
