Alterations in peroxisome-mitochondria interplay in skeletal muscle accelerate muscle dysfunction.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Skeletal muscles, which constitute 40-50% of body mass, regulate whole-body energy expenditure and glucose and lipid metabolism. Peroxisomes are dynamic organelles that play a crucial role in lipid metabolism and clearance of reactive oxygen species, however their role in skeletal muscle remains poorly understood. To clarify this issue, we generated a muscle-specific transgenic mouse line with peroxisome import deficiency through the deletion of peroxisomal biogenesis factor 5 (Pex5). Here, we show that Pex5 inhibition results in impaired lipid metabolism, reduced muscle force and exercise performance. Moreover, mitochondrial structure, content, and function are also altered, accelerating the onset of age-related structural defects, neuromuscular junction degeneration, and muscle atrophy. Consistent with these observations, we observe a decline in peroxisomal content in the muscles of control mice undergoing natural aging. Altogether, our findings show the importance of preserving peroxisomal function and their interplay with mitochondria to maintain muscle health during aging.
