Ethanol induced oxidative stress, mitochondrial dysfunction, and autophagy in Wickerhamomyces anomalus.
Article in Microbial cell factories, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Wickerhamomyces anomalus, a flavor-modulating non-Saccharomyces yeast used in winemaking, experiences escalating ethanol stress during fermentation, yet the physiological and structural consequences remain unclear. This study assessed responses to 9% (v/v) ethanol stress with and without exogenous antioxidants (10 mM N-acetylcysteine and 2.5 mM glutathione) by measuring: reactive oxygen species (ROS) via fluorescence staining; superoxide dismutase (SOD) and catalase (CAT) activities plus glutathione content colorimetrically; mitochondrial membrane potential using rhodamine 123; ultrastructure via transmission electron microscopy; electron transport chain complex activities and ATP levels colorimetrically; and autophagy via monodansylcadaverine staining. Results indicated ethanol exposure induced ROS overproduction and oxidative stress while concurrently activating SOD and catalase activities and increasing GSH. Furthermore, ethanol reduced mitochondrial membrane potential, inhibited electron transport chain activity, decreased ATP synthesis, and triggered autophagy. Conversely, antioxidant supplementation alleviated oxidative damage, restored mitochondrial function, suppressed autophagy, and enhanced cell viability. These findings elucidate ethanol's mechanistic toxicity in yeast and provide a foundation for developing antioxidant-enhanced, ethanol-tolerant W. anomalus strains for industrial fermentation.
