Co-expression of a pair of interdependent regulators coding genes ovmZ and ovmW awakens the production of angucyclinones antibiotics in Streptomyces neyagawaensis.

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.
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
backgroundMicrobial genome sequencing and analysis revealed the presence of abundant silent secondary metabolites biosynthetic gene clusters (BGCs) in streptomycetes. Activating these BGCs has great significance for discovering new compounds and novel biosynthetic pathways.
resultsIn this study, we found that ovmZ and ovmW homologs, a pair of interdependent transcriptional regulators coding genes, are widespread in actinobacteria and closely associated with the biosynthesis of secondary metabolites. Through co-overexpression of native ovmZ and ovmW in Streptomyces neyagawaensis NRRL B-3092, a silent type II polyketide synthase (PKS) gene cluster was activated to produce gephyromycin A, tetrangomycin and fridamycin E with the yields of 22.3 ± 8.0 mg/L, 4.8 ± 0.5 mg/L and 20.3 ± 4.1 mg/L respectively in the recombinant strain of S.ne/pZ
conclusionA silent angucyclinone BGC was activated by overexpressing both ovmZ and ovmW in S. neyagawaensis. Due to the wide distribution of ovmZ and ovmW in the BGCs of actinobacteria, co-overexpression of ovmZ and ovmW could be a strategy for activating silent BGCs, thus stimulating the biosynthesis of secondary metabolites.
