Quantitative analysis of small RNA pseudouridylation reveals interplay of PUS enzymes in tRNA anticodon stem-loop.

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
Pseudouridine (Ψ) is an abundant modification in small RNA catalyzed by multiple pseudouridine synthases (PUSs). However, the substrate specificity of human PUSs remains elusive. Here, we adopted PRAISE, a quantitative Ψ detection method, to profile pseudouridylation in small RNA, including cytosolic and mitochondrial tRNAs, snRNA, and snoRNA. We found that snoRNA pseudouridylation is mediated not only by RNA-guided DKC1, but also by the stand-alone enzyme PUS7 at a specific site. Interestingly, several PUS enzymes, including PUS1, RPUSD1, and PUS7, which install nearby Ψ sites within tRNA anticodon stem-loop, can influence pseudouridylation catalyzed by other PUSs, revealing an unrecognized interplay during Ψ formation. For the three RluA family enzymes, RPUSD1 catalyzes the canonical Ψ30 in tRNA-Ile and Ψ72 in tRNA-Arg isoacceptors. RPUSD2 pseudouridylates Ψ31 of mt-tRNA
