Unveiling the thioredoxin fold: a systematic review and bioinformatic analysis of protein disulfide isomerase and Dsb family proteins.

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
Introduction: Protein Disulfide Isomerases (PDIs) and bacterial Dsb proteins are key members of the thioredoxin-fold superfamily, essential for oxidative protein folding in eukaryotic and prokaryotic systems, respectively. Despite their differences in cellular context, these proteins share a conserved thioredoxin domain architecture that enables catalysis of disulfide bond formation, isomerization, and reduction. This systematic review integrates biochemical, structural, and bioinformatic data to identify conserved features within the PDI and Dsb families that underline their catalytic functions. Methods: Using a PRISMA-based methodology, we screened and analyzed 96 relevant articles and conducted a comparative structural analysis of 11 representative PDI proteins, most of which lack experimentally resolved structures. We leveraged AlphaFold models alongside crystal structures of canonical PDI (PDIA1), DsbC, and DsbG. Results: We reveal conserved tertiary folds, catalytic motifs, and domain arrangements across species. These findings highlight the evolutionary conservation and structural versatility of thioredoxin-fold enzymes and underscore their biomedical relevance in diseases linked to protein misfolding, such as neurodegeneration, cancer, and infection. Discussion: The results offer a foundation for future experimental studies and therapeutic exploration targeting redox-regulating thioredoxin-fold proteins.
