1 · What the graph read from it

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.

2 · The registry

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

The translation machinery deciphers genetic information encoded within mRNAs to synthesize proteins needed for various cellular functions. Defective mRNAs that lack in-frame stop codons trigger non-productive stalling of ribosomes. We investigated how cells deal with such defective mRNAs, and present evidence to demonstrate that RNase R, a processive 3'-to-5' exoribonuclease, is recruited to stalled ribosomes for the specific task of degrading defective mRNAs. The recruitment process is selective for non-stop mRNAs and is dependent on the activities of SmpB protein and tmRNA. Most intriguingly, our analysis reveals that a unique structural feature of RNase R, the C-terminal lysine-rich (K-rich) domain, is required both for productive ribosome engagement and targeted non-stop mRNA decay activities of the enzyme. These findings provide new insights into how a general RNase is recruited to the translation machinery and highlight a novel role for the ribosome as a platform for initiating non-stop mRNA decay.
