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

Quorum sensing (QS) is a cell density-dependent signaling mechanism used by many bacteria to control gene expression. Several recent reports indicate that the signaling molecules (autoinducers) that mediate QS in Pseudomonas aeruginosa may also modulate gene expression in host cells; however, the mechanisms are largely unknown. Here we show that two P. aeruginosa autoinducers, N-3-oxododecanoyl-homoserine lactone and N-butyryl-homoserine lactone, can both enter eukaryotic cells and activate artificial chimeric transcription factors based on their cognate transcriptional activators, LasR and RhlR, respectively. The autoinducers promoted nuclear localization of chimeric proteins containing the full LasR or RhlR coding region, and the LasR-based proteins were capable of activating transcription of a LasR-dependent luciferase gene. Responsiveness to autoinducer required the N-terminal autoinducer-binding domains of LasR and RhlR. Truncated proteins consisting of only the C-terminal helix-turn-helix DNA-binding domains of both proteins attached to a nuclear localization signal efficiently translocated to the nucleus in the absence of autoinducer, and truncated LasR-based proteins functioned as constitutively active transcription factors. Chimeric LasR proteins were only activated by their cognate autoinducer ligand and not by N-butyryl-L-homoserine lactone. These data provide evidence that autoinducer molecules from human pathogens can enter mammalian cells and suggest that autoinducers may influence gene expression in host cells by interacting with and activating as-yet-unidentified endogenous proteins.
