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

Prolonged cultivation of certain filamentous fungi, including IMPORTANCE: Prolonged cultivation of certain filamentous fungi, including Aspergillus terreus, on drug-free medium leads to degeneration and morphological heterogeneity, marked by the emergence of fluffy mycelium-type sectors. This phenomenon may indicate alterations in antifungal susceptibility profiles (particularly to amphotericin B (AmB) in A. terreus), as well as reductions or losses in conidiation, sexuality, secondary metabolite production, and/or virulence. In the present study, various characteristics of an AmB-resistant wild-type strain (WT) and its AmB-susceptible sectorized derivative (ATSec) were characterized. Compared to WT, ATSec exhibited increased susceptibility to AmB, reduced sporulation, and comparable sterol contents and virulence in Galleria mellonella. To elucidate the genes involved in AmB resistance, gene expression levels were compared between WT and ATSec with and without AmB treatment. The expression of P-type ATPase-related genes, which are implicated in membrane composition changes and consequently in AmB resistance, was significantly higher in the WT strain compared to ATSec. Moreover, the up-regulation of genes involved in the biosynthesis of polyketides - a diverse group of secondary metabolites - was higher in WT compared to ATSec, with a significant number of these genes also carrying at least one mutation. The findings of this study indicate that P-type ATPases may significantly be involved in AmB susceptibility and resistance observed in ATSec and WT strains. Additionally, mutations in polyketide synthase genes in ATSec may contribute to the phenotypic alterations associated with the sectorized phenotype.
