LRG1 Drives Pathological Angiogenesis by Disrupting Neutrophil Mitochondrial Homeostasis in Bladder Cancer

open access: yesAdvanced Science, EarlyView.
In bladder cancer, LRG1 binds to ANXA2 to trigger mitochondrial ROS‐dependent NETosis. This pathogenic cascade actively uncouples endothelial‐mural cell interactions, driving profound vascular destabilization. Consequently, targeting the LRG1‐ANXA2 axis attenuates the neutrophil burden and induces structural vascular normalization, offering a powerful ...

N-glycosylation pattern of human placental insulin-like growth factor and insulin receptors in well-controlled pregestational diabetes mellitus [PDF]

open access: yesJournal of Medical Biochemistry, 2012
Diabetes mellitus is a complex disease that leads to alterations in the glycosylation of proteins. Insulin-like growth factor and insulin receptors are involved in the regulation of fetal and placental growth and development.

Deep Learning Prediction of O‐Glycopeptide Tandem Mass Spectra Enhances O‐Glycoproteomics

open access: yesAdvanced Science, EarlyView.
DeepGPO integrates Transformer and graph neural networks with tailored training strategies, including data augmentation, loss re‐weighting, and pre‐training, to achieve high‐quality O‐glycopeptide MS/MS spectra prediction. The predicted MS/MS spectra are used to localize O‐glycosylation sites from HCD MS/MS data, enhancing O‐glycoproteomics analysis ...

Chemoenzymatic Synthesis of Heparan Sulfate Oligosaccharides by a Covalent Catch‐and‐Release Approach

open access: yesAngewandte Chemie, EarlyView.
A glycan having a hydrazide tag enables chemoenzymatic synthesis of HS oligosaccharides. The hydrazide can, under mild acidic conditions, react with an aldehyde‐containing resin to give an immobilized hydrazone that is stable under neutral conditions, allowing washing. The product can be released by transiminolysis using aqueous hydroxylamine to give a

BCG HSP70 Reprograms Macrophages via Central Trained Immunity to Suppress Prostate Cancer

open access: yesAdvanced Science, EarlyView.
BCG‐derived HSP70 (Dnak) safely induces central trained immunity via epigenetic, metabolic, and O‐GlcNAcylation reprogramming of bone marrow progenitors, driving tumor‐associated macrophages toward an M1‐like phenotype to suppress prostate cancer. ABSTRACT Trained immunity offers a promising yet clinically challenging strategy for cancer immunotherapy,

METTL7A Downregulation Drives SLC1A5‐Mediated Glutamine Competition to Promote Tumor Proliferation and Suppress CD8+ T Cell Immunity in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
GC cells enhance glutamine accumulation by upregulating SLC1A5 expression. This upregulation not only boosts GC cell proliferation, but also outcompetes CD8+ T cells for glutamine and suppresses their antitumor immunity. Mechanistically, METTL7A deficiency in GC induces SLC1A5 overexpression via an m6A‐dependent pathway and N‐glycosylation ...
