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

Plantaricin NC8 (PLNC8), a coculture-inducible two-peptide bacteriocin from Lactobacillus plantarum NC8, has recently been purified and genetically characterized. Analysis of an 8.1-kb NC8 DNA region downstream of the PLNC8 operon revealed the presence of at least four operons involved in bacteriocin production, showing high homology to the plantaricin cluster in L. plantarum C11. However, we found a three-component regulatory operon involving a quorum-sensing mechanism. Two of these components, the induction factor (PLNC8IF) and the histidine kinase, are novel, while the response regulator is identical to PlnD from C11. Homologous expression of plNC8IF in NC8 allowed constitutive bacteriocin production. Heterologous expression of this gene in Lactococcus lactis MG1363 produced supernatants which promoted bacteriocin production in NC8. Reverse transcription-PCR studies indicated that cocultivation of NC8 with inducing cells promoted transcription of the bacteriocin and regulatory operons in NC8. An identical result was obtained after addition of an external source of PLNC8IF. We propose that the presence of specific bacteria could act as an environmental signal that is able to switch on bacteriocin production in L. plantarum NC8 via a quorum-sensing mechanism mediated by PLNC8IF.
