Acrylamide-Induced Developmental and Molecular Toxicity in Drosophila melanogaster: The Role of Vanillic Acid in CncC/Keap1 Modulation.
Article in Journal of biochemical and molecular toxicology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Acrylamide, a chemical used in industrial applications, has been classified as an environmental toxin owing to its widespread contamination of drinking water and groundwater resources. Vanillic acid (VA) is a phenolic compound naturally occurring in numerous dietary sources and medicinal plants. VA exhibits a wide range of pharmacological properties, including antioxidant, anti-inflammatory, and neuroprotective activities. This study investigated the protective effects of VA against acrylamide-induced oxidative stress in Drosophila melanogaster at developmental, biochemical, and molecular levels. D. melanogaster were exposed to acrylamide (2 mM) alone or with VA at three doses (0.1, 0.5, and 1 mg/L). Acrylamide exposure elevated reactive oxygen species and lipid peroxidation, decreased antioxidant enzyme activities (SOD, CAT) and glutathione (GSH) levels, increased DNA damage by the Comet assay, upregulated mRNA expression of stress-related genes (SOD, CAT, gclc and hsp70) and detoxification-pathway components (Keap1 and CncC/Nrf2), and adversely affected developmental parameters (larval toxicity, crawling, climbing, survival, food intake, body weight and length). Co-administration of VA dose-dependently reduced lipid peroxidation and ameliorated antioxidant enzyme activities and DNA damage. VA also modulated the impaired developmental parameters of acrylamide-exposed larvae. These findings indicate that VA possesses considerable protective potential against acrylamide toxicity, with important implications for environmental and human health.
