An endocannabinoid catabolic enzyme FAAH and its paralogs in an early land plant reveal evolutionary and functional relationship with eukaryotic orthologs.
Article in Scientific reports, 2020. 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
Endocannabinoids were known to exist only among Animalia but recent report of their occurrence in early land plants prompted us to study its function and metabolism. In mammals, anandamide, as an endocannabinoid ligand, mediates several neurological and physiological processes, which are terminated by fatty acid amide hydrolase (FAAH). We identified nine orthologs of FAAH in the moss Physcomitrella patens (PpFAAH1 to PpFAAH9) with amidase signature and catalytic triad. The optimal amidase activity for PpFAAH1 was at 37 °C and pH 8.0, with higher specificity to anandamide. Further, the phylogeny and predicted structural analyses of the nine paralogs revealed that PpFAAH1 to PpFAAH4 were closely related to plant FAAH while PpFAAH6 to PpFAAH9 were to the rat FAAH, categorized based on the membrane binding cap, membrane access channel and substrate binding pocket. We also identified that a true 'dynamic paddle' that is responsible for tighter regulation of FAAH is recent in vertebrates and absent or not fully emerged in plants and non-vertebrates. These data reveal evolutionary and functional relationship among eukaryotic FAAH orthologs and features that contribute to versatility and tighter regulation of FAAH. Future studies will utilize FAAH mutants of moss to elucidate the role of anandamide in early land plants.
