Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Anti-influenza neuraminidase inhibitor oseltamivir phosphate induces canine mammary cancer cell aggressiveness. [PDF]
Oseltamivir phosphate is a widely used anti-influenza sialidase inhibitor. Sialylation, governed by sialyltransferases and sialidases, is strongly implicated in the oncogenesis and progression of breast cancer.

Abstract Background Lysosomal dysfunction is central to Parkinson's disease (PD) pathogenesis, with GBA1 representing the strongest established genetic risk factor. Numerous other genes involved in lysosomal sphingolipid, glycosphingolipid, and ceramide metabolism have been proposed as contributors to PD, highlighting the need for genetic analyses ...

Virus‐Mediated Self‐Assembly of Functional Cyclodextrins for Antiviral Inhibition
A sialic acid (SA)‐functionalized cyclodextrin (CD) self‐assembles on SARS‐CoV‐2 through ligand–receptor recognition, nucleating cooperative supramolecular polymer growth that blocks infection. The adaptive assembly requires both ligand binding and host–guest polymerization, remains active across variants, and can be tuned by coassembly, establishing ...

Assessment of Lectin Staining Biomarkers for GNE Myopathy Gene Therapy
ABSTRACT Introduction/Aims GNE myopathy (GNEM) is a rare, autosomal recessive disorder caused by mutations in the UDP‐N‐acetylglucosamine (GlcNAc) 2‐epimerase/N‐acetylmannosamine (ManNAc) kinase (GNE) gene, which encodes a required enzyme for sialic acid (SA) biosynthesis.

Targeting sialylation to treat central nervous system diseases. [PDF]
Sialic acid-binding immunoglobulin-type lectins (SIGLECs) are membrane receptors that are preferentially expressed on immune cells and recognize sialylated proteins, lipids, and RNA.

Peptide‐directed nanovehicles enabling tumor‐selective ROS amplification and antitumor immunity
Cancer cells are vulnerable to oxidative stress, yet exploit immune tolerance to escape destruction. In contrast, their metabolic profile is markedly altered to support rapid proliferation, accompanied by elevated production of reactive oxygen species (ROS).

Serum sialylation changes in cancer [PDF]
Cancer is a major cause of death in both developing and developed countries. Early detection and efficient therapy can greatly enhance survival. Aberrant glycosylation has been recognized to be one of the hallmarks of cancer as glycans participate in many cancer-associated events. Cancer-associated glycosylation changes often involve sialic acids which

Biosynthesis of sialylated and fucosylated selectin ligands of HL-60 cells in vitro Midchain α3-fucose units inhibit terminal α6-sialylation but not α3-sialylation of polylactosamines [PDF]
Polylactosamines Neu5Acα2-3′Lexβ1-3′Lexβ1-3′Lex and Neu5Acα2-3′LNβ1-3′Lexβ1-3′Lex [Lex, Galβ1-4(Fucα1-3)GlcNAc; LN, Galβ1-4GlcNAc] decorate selectin counterreceptors in human HL-60 cells.

Oxidative stress‐driven metabolic reprogramming defines two subtypes of cutaneous melanoma
Cutaneous melanoma exhibits substantial molecular heterogeneity, and metabolic reprogramming may contribute to differences in tumor behavior and treatment response. In this study, we integrated multi‐omics data from SKCM cohorts to identify two metabolism‐associated subtypes with distinct oxidative stress profiles, immune microenvironments, prognostic ...
