Metabolomic and Proteomic Profiling of Serum-Derived Extracellular Vesicles from Early-Stage Amyotrophic Lateral Sclerosis Patients.
Article in Journal of molecular neuroscience : MN, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The identification of reliable biomarkers for amyotrophic lateral sclerosis (ALS) is an unmet medical need for the development of diagnostic and therapeutic strategies. Brain-derived extracellular vesicles (EVs) have been described in peripheral blood serum and used as a direct readout of the status of the central nervous system. Here, we aimed to explore exosome-enriched EVs (referred to simply as EVs) from ALS patients via omics analysis at an early disease stage. Serum EVs were obtained from 9 healthy controls and 9 ALS patients. After EV purification, proteomic (LC‒MS/MS followed by TimsTOF Pro Mass Spectrometry) and metabolomic (Q Exactive mass spectrometer) analyses were performed. No differences in the size or concentration of EVs were observed between the controls and ALS patients. Proteomic analysis revealed 45 proteins differentially expressed in the EVs of ALS patients compared with those of controls. Metabolomic analysis revealed several distinctly represented metabolites involved in the citrate cycle and complex lipid metabolism between patients and controls. Interomics correlation analysis revealed 2 modules that were strongly associated with ALS and included several lipid metabolism-related proteins and metabolites. This study is the first to evaluate EVs by integrated proteomics and metabolomics in early-stage ALS patients, highlighting the technological progress in global inter-omics explorations of small biological samples. The differences observed in the levels of several exosomal proteins and metabolites, including phospholipids, could be used to identify serum biomarkers and novel players involved in ALS pathogenesis.
