Systemic proteomic dynamics of acute exercise reveal genetic links to health and disease.
Article in Nature metabolism, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Physical activity improves metabolic health, but the molecular responses that mediate its benefits are not fully characterized. Here we present a high-resolution, time-resolved proteomics atlas across plasma, saliva and urine from 25 healthy men in response to acute exercise. We find that exercise regulates more than 3,000 proteins through distinct, fluid-specific temporal dynamics. Network analysis uncovers coordinated remodelling of protein secretion, extracellular matrix and immune activation across body fluids. Replication in an independent cohort shows that many exercise-responsive plasma proteins exhibit consistent responses across age, sex and exercise modalities. Integration with human genome-wide association study data links secreted, exercise-responsive proteins to cardiometabolic diseases. Functional validation of genetically prioritized muscle-specific secreted proteins in Drosophila confirms their role in endurance, behaviour and metabolism. Overall, this open-access atlas ( https://cbmr.ku.dk/research/research-groups/deshmukh-group/shiny-apps/ ) provides a multifluid resource that complements existing exercise-omics efforts for defining molecular adaptations to exercise and for prioritizing candidate exerkines.
