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

The orthologous penR and pntR genes from the pentalenolactone biosynthetic gene clusters of Streptomyces exfoliatus UC5319 and S. arenae TÜ469, respectively, were predicted to encode MarR/SlyA family transcriptional regulators, responsible for regulation of the biosynthesis of the sesquiterpenoid antibiotic pentalenolactone. The intrinsic target DNA sequences and small molecule ligands of purified recombinant PenR and PntR were identified by electrophoretic mobility shift assays. PenR bound to DNA from both the penR-gapN and penM-penH intergenic regions, while PntR bound only the corresponding pntR-gapR intergenic region. The targets of PenR and PntR were shown to be limited to conserved 37-bp DNA segments. Pentalenolactone and two late-stage biosynthetic intermediates, pentalenolactones D and F, act as ligands of both PenR and PntR, resulting in release of these proteins from their target DNA. The production of pentalenolactones was significantly decreased in the penR deletion mutant S. exfoliatus ΔpenR ZD27 but could be restored by complementation with either penR or pntR. Reverse transcription-PCR established that transcription of pentalenolactone biosynthetic and resistance genes decreased, while that of the penR gene itself increased in the penR deletion mutant S. exfoliatus ZD27 compared to the wild-type strain. The PenR protein thus serves as a positive regulator of pentalenolactone biosynthesis and self-resistance while acting as an autorepressor of penR.
