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

Invasive fungal infections are a leading cause of human mortality. Effective treatment is hindered by the rapid emergence of resistance to the limited number of antifungal drugs, demanding new strategies to treat life-threatening fungal infections. Here, we explore a powerful strategy to enhance antifungal efficacy against leading human fungal pathogens by using the natural product beauvericin. We found that beauvericin potentiates the activity of azole antifungals against azole-resistant Candida isolates via inhibition of multidrug efflux and that beauvericin itself is effluxed via Yor1. As observed in Saccharomyces cerevisiae, we determined that beauvericin inhibits TOR signaling in Candida albicans To further characterize beauvericin activity in C. albicans, we leveraged genome sequencing of beauvericin-resistant mutants. Resistance was conferred by mutations in transcription factor genes TAC1, a key regulator of multidrug efflux, and ZCF29, which was uncharacterized. Transcriptional profiling and chromatin immunoprecipitation coupled to microarray analyses revealed that Zcf29 binds to and regulates the expression of multidrug transporter genes. Beyond drug resistance, we also discovered that beauvericin blocks the C. albicans morphogenetic transition from yeast to filamentous growth in response to diverse cues. We found that beauvericin represses the expression of many filament-specific genes, including the transcription factor BRG1 Thus, we illuminate novel circuitry regulating multidrug efflux and establish that simultaneously targeting drug resistance and morphogenesis provides a promising strategy to combat life-threatening fungal infections.
