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

Although the mechanism by which the cyclic AMP receptor protein (CRP) regulates global gene transcription has been intensively studied for decades, new discoveries remain to be made. Here, we report that, during rapid growth, CRP associates with both the well-conserved, dual-function DNA-binding protein peptidase A (PepA) and the cell membrane. These interactions are not present under nutrient-limited growth conditions, due to post-translational modification of three lysines on a single face of CRP. Although coincident DNA binding is rare, dissociation from CRP results in increased PepA occupancy at many chromosomal binding sites and differential regulation of hundreds of genes, including several encoding cyclic dinucleotide phosphodiesterases. We show that PepA represses biofilm formation and activates motility/chemotaxis. We propose a model in which membrane-bound CRP interferes with PepA DNA binding. Under nutrient limitation, PepA is released. Together, CRP and free PepA activate a transcriptional response that impels the bacterium to seek a more hospitable environment. This work uncovers a function for CRP in the sequestration of a regulatory protein. More broadly, it describes a paradigm of bacterial transcriptome modulation through metabolically regulated association of transcription factors with the cell membrane.
