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

Reporter assays are widely used in applications that require measurement of changes in gene expression over time (e.g. drug screening). With standard reporter vectors, the measurable effect of a treatment or compound (altered reporter activity) is substantially diluted and delayed, compared with its true effect (altered transcriptional activity). This problem is caused by the relatively long half-lives of both the reporter protein and its mRNA. As a result, the activities of compounds, ligands or treatments that have a relatively minor effect, or a substantial but transient effect, often remain undetected. To circumvent this problem, we introduced modular protein- and mRNA-destabilizing elements into a range of commonly used reporters. Our data show that both elements are required for maximal responses to both increases and decreases in transcriptional activity. The double-destabilized reporter vectors showed markedly improved performance in drug screening, kinetic assays and dose-response titrations.
