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

Escherichia coli contains 30 two-component systems (TCSs), each consisting of a histidine kinase and a response regulator. Whereas most TCSs are well characterized in this model organism, little is known about the YpdA/YpdB system. To identify YpdB-regulated genes, we compared the transcriptomes of E. coli cells overproducing either YpdB or a control protein. Expression levels of 15 genes differed by more than 1.9-fold between the two strains. A comprehensive evaluation of these genes identified yhjX as the sole target of YpdB. Electrophoretic mobility shift assays with purified YpdB confirmed its interaction with the yhjX promoter. Specifically, YpdB binds to two direct repeats of the motif GGCATTTCAT separated by an 11-bp spacer in the yhjX promoter. yhjX encodes a cytoplasmic membrane protein of unknown function that belongs to the major facilitator superfamily of transporters. Finally, we characterized the pattern of yhjX expression and identified extracellular pyruvate as a stimulus for the YpdA/YpdB system. It is suggested that YpdA/YpdB contributes to nutrient scavenging before entry into stationary phase.
