Copper Chelation by Penicillamine Protects Against Doxorubicin-Induced Cardiomyopathy by Suppressing FDX1-Mediated Cuproptosis.
Article in Biomolecules, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundThe cardiotoxic effects of doxorubicin (DOX), a powerful chemotherapeutic drug, are widely recognized. Cuproptosis, a unique copper-dependent form of controlled cell death, may be involved in DOX-induced cardiomyopathy, according to recent findings. This study employs both in vivo and in silico procedures to investigate the protective effects of the copper chelator penicillamine (PEN) and the role of cuproptosis in DOX-related cardiotoxicity.
methodsThirty-two adult Sprague Dawley rats were allocated into four groups (
resultsDOX administration induced significant cardiac dysfunction, oxidative stress, and upregulation of cuproptosis markers. PEN treatment mitigated these effects, improved cardiac function, reduced fibrosis, and suppressed the expression of cuproptosis-related
conclusionThis study provides experimental evidence implicating cuproptosis in DOX-induced cardiomyopathy. PEN exerts cardioprotection, potentially by targeting this pathway, offering a promising therapeutic strategy.
