Expressing intrinsically-disordered tardigrade proteins has positive effects on acute but not chronic stress tolerance in Saccharomyces cerevisiae.
Article in PloS one, 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
The production of high value and commodity chemicals, biopharmaceuticals and biofuels using Saccharomyces cerevisiae is hindered by various stress factors that affect yield and efficiency. Tardigrades, known for their remarkable stress tolerance, express unique proteins responsible for their resilience. This study evaluates the impact of expressing the tardigrade proteins CAHS3, MAHS, and RvLEAM on stress tolerance in S. cerevisiae. Our results show that high yields of these proteins do not impede yeast growth, except for CAHS3, which reduces proliferation. Expression of MAHS enhances acute heat tolerance, while MAHS and RvLEAM confer increased tolerance to acute hyperosmotic stress. Both CAHS3 and RvLEAM improve desiccation survival. However, these proteins do not provide benefits under chronic stress conditions such as prolonged exposure to high temperature, hyperosmotic stress, or solvents. These findings highlight the potential utility of tardigrade proteins for transient stress protection in industrial bioprocesses and suggest future engineering approaches for improved stress tolerance in yeast.
