Chrysophanol Attenuates Cognitive Impairment, Neuroinflammation, and Oxidative Stress by TLR4/ NFκB-Nrf2/HO-1 Signaling in Ethanol-Induced Neurodegeneration.
Article in Neurochemical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Ethanol-induced neurodegeneration refers to the progressive loss of structure and function of neurons caused by chronic ethanol consumption. According to the World Health Organization (WHO), over 2.3 billion people globally consume alcohol. This contributes to a significant amount of alcohol-related brain damage. This study evaluated the effect of chrysophanol in ethanol-induced neurodegeneration. Mice were administered 10 mg/kg i.p. chrysophanol, 30 min after a 2 g/kg i.p. injection of ethanol, for 11 days. Y-maze, Morris water maze (MWM), and novel object recognition (NOR) test were carried out to analyze learning and memory impairment. Analysis of antioxidant levels, histopathological examinations, measurement of COX-2 & NLRP3 using ELISA, and gene expression analysis of TLR4, NFκB, IL-1β, TNF-α, Caspase-3, and Nrf-2, HO-1, and in hippocampus and cortex using RT-PCR, as well as DNA damage by comet assay, were carried out. Chrysophanol has shown a remarkable impact in reversing cognitive decline and spatial memory. It effectively boosted antioxidant levels such as GSH, GST, and CAT, while simultaneously reducing the levels of MDA and NO. The histopathological analysis also showed improvement in overall morphology and survival of neurons. Chrysophanol treatment effectively showed an increase in the expression of HO-1 and Nrf-2, with a decrease in TLR4, NFκB, IL-1β, TNF-α, and Caspase-3 expression confirmed through RT-PCR. Production of inflammatory cytokines and apoptotic gene expression was successfully reversed after chrysophanol treatment. COX-2 & NLRP3 levels decreased, and an improvement in DNA damage was observed after chrysophanol treatment. In conclusion, chrysophanol demonstrated remarkable neuroprotective activity against ethanol-induced neurodegeneration.
