Ribosomal A-site interactions with near-cognate tRNAs drive stop codon readthrough.
Article in Nature structural & molecular biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Transfer RNAs (tRNAs) serve as a dictionary for the ribosome translating the genetic message from mRNA into a polypeptide chain. In addition to this canonical role, tRNAs are involved in other processes such as programmed stop codon readthrough (SC-RT). There, tRNAs with near-cognate anticodons to stop codons must outcompete release factors and incorporate into the ribosomal decoding center to prevent termination and allow translation to continue. However, not all near-cognate tRNAs promote efficient SC-RT. Here, with the help of Saccharomyces cerevisiae and Trypanosoma brucei, we demonstrate that those tRNAs that promote efficient SC-RT establish critical contacts between their anticodon stem (AS) and ribosomal proteins Rps30/eS30 and Rps25/eS25 forming the decoding site. Unexpectedly, the length and well-defined nature of the AS determine the strength of these contacts, which is reflected in organisms with reassigned stop codons. These findings open an unexplored direction in tRNA biology that should facilitate the design of artificial tRNAs with specifically altered decoding abilities.
