Network pharmacology and experimental validation reveal dexmedetomidine's protective mechanisms against acute liver injury in mice.

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
This study explored the role and molecular mechanisms of dexmedetomidine (DEX), an α2-adrenergic receptor agonist, in the treatment of a mouse model of acute liver injury (ALI). DEX significantly mitigated hepatic tissue damage and reduced serum levels of liver function biomarkers and proinflammatory cytokines. Network pharmacology analysis revealed 81 common targets between DEX and ALI, identifying 10 crucial hub genes. Kyoto Encyclopedia of Genes and Genomes pathway analysis indicated that DEX's therapeutic effect on ALI is likely linked to the activation of the PI3K/AKT pathway. Immunohistochemical experiments verified DEX's activation of the PI3K/AKT pathway. Molecular docking and dynamic simulations confirmed the stable interaction between DEX and the epidermal growth factor receptor (EGFR). Immunohistochemistry and western blotting further validated that DEX pretreatment upregulated EGFR expression. Our findings indicate that DEX may mitigate ALI by interacting with EGFR and triggering the PI3K/AKT pathway. These findings provide a solid theoretical and experimental basis for using DEX as a potential therapeutic regimen for treating inflammatory liver diseases.
