| contents | Ethanol extracts of Isochrysis zhanjiangensis alleviate acute alcoholic liver injury and modulate intestinal bacteria dysbiosis in mice Yangmin Wen Youcai Zhou Li Tian Yongjin He Journal of the Science of Food and Agriculture AbstractBACKGROUNDAlcoholic liver disease (ALD) is responsible for 3.3 million deaths per annum. Efficacious therapeutic modalities or drug treatments for ALD have not yet been found, so it is urgent to seek new agents for preventing ALD and its related disease. Many experiments have indicated that modulating the gut microbiota and regulating the toll‐like receptor 4 (TLR4)/nuclear transcription factor‐κB (NF‐κB) inflammatory pathway can provide a new target for prevention and treatment of ALD. Marine microalgae have their natural metabolic pathways to synthesize various of bioactive compounds as promising candidates for hepatoprotection. In this study, we investigated ethanol extracts from Isochrysis zhanjiangensis (EEIZ) to evaluate their ability to alleviate acute alcoholic liver injury, regulate TLR4/NF‐κB inflammatory pathway and modulate intestinal bacteria dysbiosis in mice for ALD treatment.RESULTSIn the acute ALD mouse model, EEIZ reduced levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, triacylglyceride, total cholesterol and low‐density lipoprotein, while increasing the level of high‐density lipoprotein. Besides, TLR4, myeloid differentiation factor 88, NF‐κB and tumor necrosis factor‐α expression levels in liver tissue were effectively downregulated by EEIZ. Furthermore, treatment with EEIZ enhanced intestinal homeostasis and significantly alleviated the damage caused by alcohol.CONCLUSIONEEIZ showed effective hepatoprotective activity against alcohol‐induced acute liver injury in mice as it could alleviate hepatocyte damage, suppress the TLR4/NF‐κB inflammatory pathway and regulate the intestinal flora structure. EEIZ could be a good candidate for preventing acute alcoholic liver injury. © 2024 Society of Chemical Industry. 10.1002/jsfa.13321 http://onlinelibrary.wiley.com/termsAndConditions#vor |
