Methylmercury demethylation and volatilization by animals expressing microbial enzymes.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Mercury is a highly toxic trace metal that readily biomagnifies in food webs where it is inaccessible to current bioremediation methods. Animals could potentially be engineered to detoxify mercury within their food webs to clean up impacted ecosystems. We demonstrate that invertebrate (Drosophila melanogaster) and vertebrate (Danio rerio) animal models can express organomercurial lyase (MerB) and mercuric reductase (MerA) from Escherichia coli to demethylate methylmercury and remove it from their biomass as volatile elemental mercury. The engineered animals accumulated less than half as much mercury relative to their wild-type counterparts, and a higher proportion of mercury in their tissue was in the form of less bioavailable inorganic mercury. Furthermore, the engineered animals could tolerate higher exposures to methylmercury compared to controls. These findings demonstrate the potential of using engineered animals for bioremediation and may be applied to reduce the burden of methylmercury in impacted ecosystems by disrupting its biomagnification or to treat contaminated organic waste streams.
