Seebio 2'-Fucose lactose and gene set enrichment analysis degrees are different. Weighted gene co-expression network analysis (WGCNA) reflected gene modules correlated to MW, the module hub genes and top GO terms showed the activation of macrophage was positively correlated with the MW, and larger MW COS activated cell death associated GO terms. Further use of the screening and enrichment functions of STRING and Pfam databases discovered that apoptosis-related pathways and protein families were activated, such as the P53 pathway and caspase protein family. qRT-PCR results showed that as the stimulation time extends, the innate immune-related and P53 pathways are gradually activated, and the degree of activation is positively correlated with the stimulation time. In addition, apoptosis was detected by immunofluorescent staining in three groups. Therefore, the use of COS has two sides-it can activate the immune system against pathogen invasion, but with the increase in stimulation time and MW, macrophage apoptosis is induced, which may be caused by abnormal replication of DNA and excessive inflammation.

This study provides a theoretical basis for the rational use of COS as an immunopotentiator in Full assignment of the proton and carbon NMR spectra and revised structure for the capsular polysaccharide from Streptococcus pneumoniae type 17F.Full proton, 13C and 31P NMR assignments for the capsular polysaccharide from Streptococcus pneumoniae Type 17F are reported, and a revised structure differing in the anomeric configuration of the sidechain beta-Galp residue proposed. This polysaccharide is a component of the current 23-valent polysaccharide vaccine. The implications of this revised structure for published Identification of O-linked oligosaccharide chains in the activation peptides of blood coagulation factor X. The role of the carbohydrate moieties in the Conversion of factor X to factor Xa results in release of a heavily glycosylated activation peptide. Analysis of protease-digested glycopeptides derived from the activation peptides of bovine and human blood coagulation factor X allowed the identification of sites of the O-linked oligosaccharide chains in these peptides. Glycopeptides were prepared from the activation peptides by digestion with chymotrypsin or Staphylococcus aureus V8 protease.

By combined analysis of amino acid sequence and sialic acid content, we found that bovine factor X had an O-linked oligosaccharide chain linked to Thr26, and human factor X had four carbohydrate-attachment sites, namely, O-glycosidic linkages to Thr17 and Thr29, respectively, and N-glycosidic linkages to Asn39 and Asn49, respectively, in their activation peptides. The O-linked carbohydrate-attachment sites were identified since the yields of phenylthiohydantoin derivatives of amino acids that corresponded to their residues were increased during amino acid sequencing after deglycosylation of the glycopeptides with sialidase and O-glycanase. The effect of deglycosylation of bovine factor X1 was investigated with factor-X-activating enzyme from Russell's viper venom or extrinsic Xase (factor VIIatissue factorphospholipid) by examining the activation rates of derivatives of factor X prepared using O-glycanase, sialidase, andor N-glycanase. Get it now of O-linked carbohydrate resulted in a decrease in the rate of activation. It appears that carbohydrate residues in factor X play an important role in the activation of the zymogen.DOI 111j432-33993.tb18361.

xImmunochemistry of some bacterial oligosaccharide protein conjugates.Oligosaccharides containing glucose and mannose in glycoproteins of the thyroid The glucose-containing oligosaccharides formed by calf thyroid slices incubated with radioactive glucose were studied. A compound soluble in chloroformmethanolwater, 11 (volvol), was found that was indistinguishable from the previously described glucose-containing dolichyl diphosphate oligosaccharide formed by liver microsomes. Glycopeptides were prepared by treating the glycoproteins with pronase, the amino acids were removed with alkaline borohydride, and the products were examined by paper electrophoresis and chromatography. A saccharide equal to that which occurs in the glucose-containing dolichyl diphosphate oligosaccharide could not be detected but glucose was found in oligosaccharides that seemed to be smaller by about three to five monosaccharide residues.
