Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry
PROTEOMICS, EarlyView.ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).

Potential clinical utility of small extracellular vesicles derived from head and neck tumours
VIEW, EarlyView.Small extracellular vesicles (EVs) carry selective protein cargoes that reflect tumour cell status, making them valuable for biomarker discovery. This study compared EV proteomes from head and neck cancer (HNC) tumour tissue, saliva and plasma. Over 60% of proteins were shared across all sources, with enrichment in cancer‐related pathways such as ...
