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

One of the prokaryotic post-transcriptional regulatory mechanisms involves the CsrA/RsmA family of proteins that act by modulating translation initiation at target mRNAs. In this study, we identified the regulon of RsmA of the Pseudomonas aeruginosa PAK strain by using cultures in the stationary phase of growth. The RsmA regulon includes over 500 genes, of which approximately one-third were affected by an rsmA mutation negatively, while the rest were affected positively. By isolating RsmA/mRNA complexes, analysing transcriptional and translational fusions, and performing gel-shift analyses, we identified 40 genes in six operons that are regulated by RsmA directly at the level of translation. All of these genes were affected by RsmA negatively and include genes encoding the type VI secretion system HSI-I, which has been implicated in the P. aeruginosa chronic infections. On the other hand, we were unable to demonstrate a direct interaction of RsmA with transcripts that are positively affected by this protein, including mRNAs encoding the type III secretion system and the type IV pili genes. Our work supports a model in which RsmA acts as a negative translational regulator, and where its positive effects are achieved indirectly by RsmA-mediated interference with translation of specific regulatory factors.
