Hetero-oligomerization drives structural plasticity of eukaryotic peroxiredoxins.
Article in Nature chemical biology, 2026. 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
Peroxiredoxins are thiol peroxidases, which detoxify peroxides, relay redox signals and act as chaperones. In eukaryotes, multiple peroxiredoxin-1 (Prx1)/AhpC-type isoforms frequently co-exist in the same subcellular compartment, yet have been assumed to assemble only as homo-oligomeric complexes. Here we show that hetero-oligomerization is a conserved and functionally relevant property of Prx1/AhpC-type peroxiredoxins. Using biochemical reconstitution, native mass photometry, electron microscopy and live-cell assays, we demonstrate formation of heterodimers and heterodecamers, with diverse subunit stoichiometries, in peroxiredoxin pairs from different eukaryotic kingdoms. In Saccharomyces cerevisiae, oxidative challenge induces Tsa1-Tsa2 heterodecamerization with substoichiometric Tsa2 incorporation sufficing to stabilize the decameric state. Functional hetero-oligomers are also observed forming among human, plant and Leishmania peroxiredoxins. Our findings provide new insights into peroxiredoxin structural plasticity with broad implications for redox biology, stress responses and cellular adaptation, and also challenge the long-held paradigm of peroxiredoxin homo-oligomerization.
