Truncated o-glycans
WebTumor-associated glycan changes comprise increased branching of N-glycans, higher density of O-glycans, generation of truncated versions of normal counterparts, and generation of unusual forms of terminal structures arising from sialylation and fucosylation. WebJan 16, 2024 · It is demonstrated that accumulation of Zn2+ in the secretory pathway coincides with cell-surface presentation of truncated O-glycans in cancer tissue, and that over-expression of COSMC mitigates such changes. In epithelial cancers, truncated O-glycans, such as the Thomson-nouveau antigen (Tn) and its sialylated form (STn), are up …

WebThe abnormal expression of immature, truncated O-glycans is a characteristic feature of nearly all epithelial cancers. One of the prime mechanisms underlying the synthesis of truncated O-glycans is a decrease in the activity of the T synthase, which leads to an accumulation in the Tn antigen. WebJul 24, 2024 · These changes might potentially enforce the capacity of differentiated cells to synthesize branched N-glycans and mucin-type O-glycans and to remodel cell surface proteoglycans. Stimulation of DCs and Mphis with lipopolysaccharide caused a general decrease in gene expression, mainly affecting genes found to be positively modulated …

WebWe demonstrate how these inhibitors can be used to manipulate glycosylation in cells to induce expression of truncated O-glycans and augment binding of cancer-specific Tn-glycoprotein antibodies and to inhibit expression of heparan sulfate and binding and infection of SARS-CoV-2. Minder weergeven WebAug 31, 2024 · Here, we investigated the changes of mucin O-glycans associated with gut microbiota using a diarrheal post-weaned piglet model. We found that diarrhea disrupted the colonic mucus layer and caused aberrant mucin O-glycans, including reduced acidic glycans and truncated glycans, leading to an impaired gut microenvironment.
WebMar 4, 2024 · Truncated O-glycans, including Tn-antigen, sTn-antigen, T-antigen, sT-antigen, are incomplete glycosylated structures and their expression occur frequently in tumor …
WebTruncated O-glycans are associated with tumor progression and their presence is strongly correlated to poor prognosis. Of the hundreds of O-glycans analyzed for the binding with NEO-201, PB has determined that NEO-201 specifically binds to the truncated Core-1 T antigen and specifically kills cells that express this target. sideshow tychusWebMass spectrometric analysis of the recombinant hybrid plasminogen activator K2tu-PA at the native glycoprotein and corresponding protein level (high mass) is described.
