Uridylation regulates mRNA decay directionality in fission yeast.
Article in Nature communications, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Cytoplasmic mRNA decay is effected by exonucleolytic degradation in either the 5' to 3' or 3' to 5' direction. Pervasive terminal uridylation is implicated in mRNA degradation, however, its functional relevance for bulk mRNA turnover remains poorly understood. In this study, we employ genome-wide 3'-RACE (gw3'-RACE) in the model system fission yeast to elucidate the role of uridylation in mRNA turnover. We observe widespread uridylation of shortened poly(A) tails, promoting efficient 5' to 3' mRNA decay and ensuring timely and controlled mRNA degradation. Inhibition of this uridylation process leads to excessive deadenylation and enhanced 3' to 5' mRNA decay accompanied by oligouridylation. Strikingly we found that uridylation of poly(A) tails and oligouridylation of non-polyadenylated substrates are catalysed by different terminal uridyltransferases Cid1 and Cid16 respectively. Our study sheds new light on the intricate regulatory mechanisms underlying bulk mRNA turnover, demonstrating the role of uridylation in modulating mRNA decay pathways.
