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

Expression of recombinant genes can be controlled using inducible promoters. However, the most commonly used IPTG- and arabinose-inducible promoters result in an 'all-or-nothing' response, leading to fully induced and uninduced bacterial subpopulations. Here, we investigate whether appropriate modifications to these promoter systems can be combined into a single vector system, enabling homogenous expression of two genes of interest that can be precisely tuned using inducer concentration. We show that modifications of positive feedback loops related to inducer uptake result in homogeneous gene expression in both the T7 lactose and pBAD arabinose systems. Furthermore, these two modified systems were combined into a single vector, pRAT-sfGFP that provides the desired tunable expression of two genes of interest. Finally, we test this single-vector system as a tool for studying two-component genetic circuits, using toxin-antitoxin modules as model systems. This novel low-copy single vector expression system opens up new possibilities for investigating the function of two-component bacterial genetic circuits.
