Cuproptosis inducers mediate cold lethality via SLCR-46.1 in C. elegans.
Article in Nature communications, 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
Cuproptosis denotes cell death triggered by copper accumulation. However, its role in natural environmental responses remains unclear. Here, we demonstrate that cuproptosis contributes to cold-induced lethality in C. elegans. A mutant for the lysosomal copper transporter gene slcr-46.1 exhibited defective cold tolerance due to copper accumulation in the pharyngeal muscle upon cold exposure. The abnormal cold tolerance of the slcr-46.1 mutant was suppressed by interference with copper homeostasis and cuproptosis-signaling genes. Chelating copper ions in the slcr-46.1 mutant rescued the abnormal cold tolerance, while inhibiting cuproptosis signaling in wild-type worms inhibited cold-induced lethality. In addition, the cold lethality in the slcr-46.1 mutant was not caused by activation of the oxidative stress pathway observed in ferroptosis (iron-dependent cell death). Here, we show evidence that cuproptosis plays a critical role in cold-induced lethality in an animal.
