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

Bacterial dual-function small RNAs regulate gene expression by RNA-RNA base pairing and also code for small proteins. SgrS is a dual-function small RNA in Escherichia coli and Salmonella that is expressed under stress conditions associated with accumulation of sugar-phosphates, and its activity is crucial for growth during stress. The base-pairing function of SgrS regulates a number of mRNA targets, resulting in reduced uptake and enhanced efflux of sugars. SgrS also encodes the SgrT protein, which reduces sugar uptake by a mechanism that is independent of base pairing. While SgrS base-pairing activity has been characterized in detail, little is known about how base pairing and translation of sgrT are coordinated. In the current study, we utilized a series of mutants to determine how translation of sgrT affected the efficiency of base pairing-dependent regulation and vice versa. Mutations that abrogated sgrT translation had minimal effects on base-pairing activity. Conversely, mutations that impaired base-pairing interactions resulted in increased SgrT production. Furthermore, while ectopic overexpression of sgrS mutant alleles lacking only one of the two functions rescued cell growth under stress conditions, the SgrS base-pairing function alone was indispensable for growth rescue when alleles were expressed from the native locus. Collectively, the results suggest that during stress, repression of sugar transporter synthesis via base pairing with sugar transporter mRNAs is the first priority of SgrS. Subsequently, SgrT is made and acts on preexisting transporters. The combined action of these two functions produces an effective stress response.
