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

Actinomycetes bacteria produce diverse bioactive molecules that are useful as drug seeds. To improve their yield, researchers often optimize the fermentation medium. However, exactly how the extracellular chemicals present in the medium activate secondary metabolite gene clusters remains unresolved. BR-1, a β-carboline compound, was recently identified as a chemical signal that enhanced reveromycin A production in Streptomyces sp. SN-593. Here we show that BR-1 specifically bound to the transcriptional regulator protein RevU in the reveromycin A biosynthetic gene cluster, and enhanced RevU binding to its promoter. RevU belongs to the LuxR family regulator that is widely found in bacteria. Interestingly, BR-1 and its derivatives also enhanced the production of secondary metabolites in other Streptomyces species. Although LuxR-N-acyl homoserine lactone systems have been characterized in Gram-negative bacteria, we revealed LuxR-β-carboline system in Streptomyces sp. SN-593 for the production of secondary metabolites. This study might aid in understanding hidden chemical communication by β-carbolines.
