Effect of Food Migrations of PEEK-Modified Atmosphere Packaging Materials on Mitochondrial Damage via PGC-1α/Nrf2 Signaling Pathway.
Article in Toxics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Poly Ether-Ether Ketone (PEEK) is used in modified atmosphere packaging (MAP) for fruit and vegetable preservation, but raises health concerns. This study investigated the effects of PEEK food migrations on liver cell mitochondrial damage. Food simulants (95% ethanol, 10% ethanol, and 4% acetic acid) were used for migration tests according to guideline recommendations, and liver cells were treated with PEEK food migrations for 24 h. Results showed decreased cell viability, increased reactive oxygen species (ROS), reduced mitochondrial membrane potential (MMP), mitochondrial DNA copy number (mtDNAcn), and down-regulated PGC-1α/Nrf2 pathway-related genes (Sirt1, PGC-1α, NRF1, Nrf2, TFAM). Furthermore, these alterations were reversed, and mitochondrial damage was alleviated by the addition of the PGC-1α activator ZLN005. In conclusion, high PEEK concentrations induce mitochondrial toxicity in liver cells via the PGC-1α/Nrf2 pathway, posing health risks and necessitating safe dosage limits in food packaging.
