Quantifying Protein–Glycan Interactions Using Native Mass Spectrometry
ABSTRACT Interactions between glycan‐binding proteins (GBPs) and carbohydrates (glycans) are essential to many biological processes relevant to human health and disease. For most GBPs, however, their glycan interactome—the repertoire of glycans recognized and their specificities—is poorly defined.

Historical Background Extracellular purine and pyrimidine nucleotides act as signaling molecules through the activation of P2X ion channels and P2Y G protein-coupled receptors (GPCRs) (Abbracchio et al. 2006). Among the eight members of the P2Y receptor

Here, we present a two-step continuous flow enzymatic synthesis process in monolithic microreactors using basic sugars as substrates. In the first step UDP-glucose pyrophosphorylase (TaGalU) catalyses the synthesis of uridine-diphosphate-glucose (UDP-Glc)

Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Quantitative analysis of the pyrimidine metabolism in pheochromocytoma PC-12 cells
A detailed quantitative study of pyrimidine metabolism in exponentially growing rat pheochromocytoma PC-12 cells has been performed. The sizes of ribonucleotide pools have been analysed and the pathways and the rates of metabolism of uridine, cytidine ...

Combating VEGFA‐siRNA‐Induced Metabolic Reprogramming via Glucose Utilization Deprivation
An ionizable lipid nanoparticle co‐delivers VEGFA siRNA and glucose oxidase to tumors to counteract VEGFA knockdown‐induced, glutamine‐driven metabolic compensation. Enzymatic glucose consumption reverses the adaptive pathways and restores metabolism toward baseline, thereby sensitizing tumors to therapy.

Oxovanadium(IV) binding to ligands containing donor sites of biological relevance
The (VO)-O-IV complex formation by a number of sugar ligands and their phosphate derivatives has been studied by the combined application of pH-potentiometric and spectroscopic (EPR and electronic absorption) techniques.

Metabolic Fingerprinting of Urine Reveals Metabolite Changes in Women With Breast Cancer
This study uses metabolomics to compare urine, plasma and serum metabolite profiles across breast cancer, benign breast disease, symptomatic and healthy controls. Significant metabolic differences—especially in amino acids—were found between BC and other groups, with moderate correlations across biofluids, suggesting potential for non‐invasive BC ...
