Effects of an ergosterol synthesis inhibitor on gene transcription of terpenoid biosynthesis in Blakeslea trispora.
Article in Current microbiology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Highly efficient induction of carotene biosynthesis of Blakeslea trispora by ketoconazole (KCZ), an inhibitor of ergosterol biosynthesis, was found previously. To get some insight into the regulatory mechanisms of KCZ controlling terpenoid (including carotene) biosynthesis, the transcript levels of gene hmgR, encoding HMGR, which initiates the biosynthesis of all terpenoids, and gene carRA, encoding lycopene cyclase and phytoene synthase in the carotene biosynthsis pathway, were investigated in B. trispora cells treated with KCZ. Upon KCZ treatment, up-regulation of hmgR and carRA genes, increased beta-carotene and ubiquinone contents, and decreased ergosterol content were all observed. The results suggest that the inhibition of ergosterol biosynthesis by KCZ triggered hmgR gene transcription, which might present a positive feedback regulation of gene hmgR in response to a depletion of ergosterol. Furthermore, KCZ could be used as a new agent to improve not only beta-carotene but also ubiquinone production, whose regulatory mechanisms controlling terpenoid biosynthesis differ from the agents reported previously.
