Brain metastasis‐associated fibroblasts shape the tumour microenvironment to enhance cancer cell invasion

open access: yesBrain Pathology, EarlyView.
Brain metastasis‐associated fibroblasts are active stromal components of the metastatic niche characterised by extracellular matrix remodelling and production of pro‐migratory mediators. They promote monocyte and cancer cell migration and enhance cancer cell invasion while having no growth‐promoting effect on cancer cells.

A posttranslational proteomic survey of a single anatomically preserved human 20‐week postconception brain

open access: yesJournal of Anatomy, EarlyView.
A well‐preserved 20 post‐conception week human brain was obtained and finely dissected into 18 anatomically distinct regions, including the pia mater. Each region underwent in‐depth proteomic analysis, encompassing both total protein content and post‐translational modifications.

Understanding extracellular vesicle biology, isolation, and characterization: The theory of EV‐erything

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.

Ovarian hormone loss modifies the nucleic acid cargo of circulating extracellular vesicles and skeletal muscle metabolism after acute exercise in rats

open access: yesExperimental Physiology, EarlyView.
Abstract Loss of ovarian hormones (i.e., menopause) leads to negative effects on metabolic health. While exercise offers significant benefits, it seems to be insufficient to completely reverse these changes. The mechanisms by which exercise conveys the effects throughout the body are still poorly understood.

Systematic Optimization of an SLE‐DAPTAD LC–MS/MS Workflow for Simultaneous Quantification of Low‐Abundance Vitamin D3 Metabolites in Plasma

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis of vitamin D3 metabolites is analytically challenging because these compounds are structurally similar, strongly matrix‐associated, and have poor ionization efficiency.
