Metabolic alterations and redox homeostasis in ferroptosis: emerging mechanisms and therapeutic implications.
Article in Archives of medical science : AMS, 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
Ferroptosis is a programmed cell death characterized by excessive, iron-dependent accumulation of membrane lipid peroxides due to insufficient glutathione-dependent antioxidant defense. It is influenced by the metabolism of amino acids, lipids, and iron, and occurs in conditions of decreased glutathione peroxidase 4 (GPX4) activity. The increased polyunsaturated fatty acid (PUFA) content in membrane phospholipids is associated with cellular hypersusceptibility to ferroptosis. In contrast, incorporation of monounsaturated fatty acids may protect cells against ferroptotic cell death. Cellular sensitivity to ferroptosis is additionally influenced by glutamine catabolism and the xc-system-mediated import of cystine, which modulate glutathione production, and by elevated iron levels, which lead to the buildup of reactive oxygen species (ROS) that attack membrane-localized PUFAs. This review focuses on recent findings of perturbed metabolic processes in cancer that create a high iron demand and an altered lipid composition, thereby predisposing cells to ferroptosis. We analyze the therapeutic potential of pharmacological agents that can selectively trigger ferroptosis in tumor cells.
