Systematic analysis of protein expression in Candida albicans exposed to farnesol.
Article in Chinese medical journal, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe phenotypic switching of Candida spp. plays an important role in the development of vulvovaginal candidiasis (VVC). Farnesol, as a quorum-sensing molecule in Candida albicans, has the ability to prevent yeast-to-hyphal conversion in vitro. However, the mechanism underlying this ability is unclear. This study aimed to investigate changes in protein levels to better understand how farnesol impacts processes contributing to VVC.
methodsThe isobaric tag for relative and absolute quantitation technique was used to detect protein expression in C. albicans strain SC5314 (ATCC MYA-2876) with or without farnesol exposure. Proteins with a threshold fold change greater than 1.5 were screened and considered differentially expressed proteins. All the altered proteins were analyzed using Gene Ontology annotation, Kyoto Encyclopedia of Genes and Genomes (KEGG) annotation, and metabolic pathway annotation.
resultsBetween the farnesol-exposed group and the farnesol-unexposd group, we detected 297 altered proteins among all 2047 tested proteins based on a threshold fold change of more than 1.5 (P < 0.05). Eighty-seven of the 297 altered proteins exhibited metabolic enzyme activity and participated in 85 metabolic pathways according to KEGG pathway analysis. Most of these metabolic pathways were associated with central carbon metabolism processes. In the sterol synthesis pathway, which involves the synthesis of farnesol, ERG25 (methylsterol monooxygenase) and ERG4 (delta 24(24(1))-sterol reductase) were both down-regulated in the farnesol-exposed group. All six altered proteases associated with the oxidative phosphorylation process were down-regulated in the farnesol-exposed group relative to the farnesol-unexposed group.
conclusionsThe mechanisms underlying farnesol-induced phenotype switching involves the adjustment of metabolic activities and epigenetic modification. Exogenous farnesol had an evident, but non-deterministic effect on the synthesis of ergosterol. The potential drug activity of farnesol warrants further investigation.
