Multi‐Technique Integration Identifies O‐GlcNAc Transferase in Fibroblast‐Like Synoviocytes as a Therapeutic Target for Rheumatoid Arthritis

Advanced Science, EarlyView.
AI‑guided single‑cell transcriptomics identifies OGT as a key regulator enriched in rheumatoid arthritis fibroblast‑like synoviocytes (RA‐FLSs). Inflammatory stimuli activate the OGT–SAP130 axis, which modulates the H3K27ac/H3K27me3 balance and epigenetically silences BTG2, promoting aggressive transformation of RA‑FLSs.

Characterization of Full‐Length Antibody Complexes Through HDX‐Mass Spectrometry Coupled With NMR Spectroscopy: New Insight Into Avelumab/PD‐L1 Interaction

Angewandte Chemie, EarlyView.
Combining HDX‐MS and NMR enables the mapping of epitopes and paratopes in full‐length antibody complexes, revealing transient interactions and potential artifacts. ABSTRACT Recombinant biomacromolecules have significantly transformed pharmaceuticals, in particular monoclonal antibodies (mAbs) that target key areas in oncology, immunology, inflammation,

Hylocereus polyrhizus Pulp Residues Polysaccharide Alleviates High-Fat Diet-Induced Obesity by Modulating Intestinal Mucus Secretion and Glycosylation

Foods
Although Hylocereus polyrhizus pulp residues polysaccharides (HPPP) have shown potential in improving metabolic disorders and intestinal barrier function, the mechanism by which they exert their effects through regulating O-glycosylation modifications in

TECTB Variants Reveal Tectorial Membrane Vulnerability in Dominant Non‐Syndromic Hearing Loss

Advanced Science, EarlyView.
TECTB is a non‐collagenous protein of the tectorial membrane – an extracellular matrix of the cochlea. This study identifies dominant missense variants in TECTB linked to human hereditary deafness in two unrelated families. Genetically engineered mice homozygous for one of the variants are profoundly deaf, whereas heterozygous mice have normal hearing ...

Atypical Condensation Domains Guide Discovery and Illuminate Biosynthesis of Myxoglucamides Featuring Vinyl‐Substituted, α‐Oxidized γ‐Amino Acids

Angewandte Chemie, EarlyView.
Genome mining of atypical condensation (C) domains leads to the discovery of myxoglucamides, glycolipopeptides featuring an unprecedented vinyl‐substituted, α‐oxidized γ‐amino acid. Biosynthetic studies reveal a discrete C‐domain‐like O‐acyltransferase, a β‐hydroxylation‐dependent chain‐extension checkpoint, and an unusual pathway for γ‐amino acid ...

Transcriptomics as a predictor of biopharmaceutically favourable glycan profiles

Frontiers in Cell and Developmental Biology
N-glycosylation plays a crucial role in defining the pharmacological properties and efficacy of therapeutic proteins, commonly referred to as biologics. The inherent complexity and lack of a templated process in glycosylation leads to a wide variation in

Molecular Glue Degraders Enhance CAPRIN1‐Dependent Lysosomal Degradation of APP and Reduce Amyloid β in Alzheimer's Disease

Advanced Science, EarlyView.
A new class of lysosome‐directed molecular glue degraders selectively enhance CAPRIN1–APP interactions, driving APP degradation and reducing amyloid‐β production in human neurons and Alzheimer's disease mouse models. This CAPRIN1‐dependent targeted protein degradation strategy reveals a previously unrecognized therapeutic approach for disrupting the ...

Intracellular Delivery of Hydrophilic Glycans Using Superchaotropic Clusters

Angewandte Chemie, EarlyView.
Superchaotropic boron clusters are demonstrated to deliver hydrophilic glycans directly into mammalian cells, removing the need for acetylation and cytotoxic solvents such as DMSO. Azido glycans for metabolic oligosaccharide engineering, and trehalose, were delivered and the successful azido‐labelling of glycoproteins, cell surface glycans, and ...

Glycosylation in the tumor immune response: the bitter side of sweetness

Acta Biochimica et Biophysica Sinica
Glycosylation is the most structurally diverse form of post-translational modification (PTM) of proteins that affects a myriad of cellular processes. As a pivotal regulator of protein homeostasis, glycosylation notably impacts the function of proteins ...
