Inhibition of Ferroptosis Attenuates Neuron Damage and Improves Cognitive Impairment in Mice Surviving Severe Hypothermia.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Survivors of severe hypothermia frequently exhibit cognitive impairments. However, the underlying mechanisms remain inadequately understood. In order to reveal the scientific problem of cognitive dysfunction caused by severe hypothermia, providing an experimental basis for clinical treatment, this study utilized animal models and combined cognitive behavioral, morphological, and molecular biological experiments. The results showed that severe hypothermia leads to an accumulation of iron ions in the cerebral cortex tissue exceeding 70%, while increased Acyl-coenzyme A synthetase long-chain family member 4 (ACSL4) expression enhances sensitivity to ferroptosis. This process results in a nearly 50% decrease in glutathione (GSH) expression and over 50% degradation of glutathione peroxidase 4 (GPX4), leading to GPX4 deactivation and increased lipid peroxidation, which in turn nearly doubles the levels of oxidative products such as MDA and 4NHE. Notably, ferroptosis inhibition using Ferrostatin-1 (Fer-1) effectively mitigates the degenerative death of cerebral cortical neurons induced by severe hypothermia, significantly improving the associated cognitive deficits. These findings suggest that severe hypothermia may induce ferroptosis in cortical neurons through the Nrf2/SLC7A11/GSH/GPX4 signaling axis. Targeted inhibition of ferroptosis has the potential to be a promising therapeutic direction for the prevention and treatment of cognitive impairment caused by severe hypothermia.
