Cholestatic liver disease, or cholestasis, is a condition characterized by liver inflammation and fibrosis following a bile duct obstruction and an intrahepatic accumulation of bile acids. Inhibiting inflammation is a promising therapeutic strategy for cholestatic liver diseases. Maxim extract (ATE) is best known for its anti-inflammatory and antioxidative properties. In this study, we investigated the effects of ATE on liver injury and fibrosis in mice with bile duct ligation (BDL)-induced cholestasis through analysis of gene expression, cytokines, and histological examination. Oral administration of ATE (20 or 50 mg/kg) for 14 days significantly attenuated hepatocellular necrosis compared to vehicle-treated BDL mice, which was accompanied by the reduced level of serum bile acids and bilirubin. We determined that ATE treatment reduced liver inflammation, oxidative stress, and fibrosis. These beneficial effects of ATE were concurrent with the decreased expression of genes involved in the NF-B pathway, suggesting that the anti-inflammatory effect of ATE could be a possible mechanism against cholestasis-associated liver injury. Our findings substantiate ATE's role as an alternative therapeutic agent for cholestasis-induced liver injury and fibrosis.
胆汁淤积性肝病,又称胆汁淤积症,是一种以胆管阻塞和肝内胆汁酸蓄积为特征的肝脏炎症和纤维化疾病。抑制炎症是治疗胆汁淤积性肝病的一种有前途的治疗策略。 Maxim 提取物(ATE)以其抗炎和抗氧化特性而闻名。在这项研究中,我们通过基因表达分析、细胞因子分析和组织学检查,研究了 ATE 对胆管结扎(BDL)诱导的胆汁淤积小鼠肝损伤和纤维化的影响。ATE(20 或 50mg/kg)连续口服 14 天可显著减轻与对照组相比,BDL 小鼠的肝细胞坏死,同时血清胆汁酸和胆红素水平降低。我们发现 ATE 治疗可减轻肝脏炎症、氧化应激和纤维化。ATE 的这些有益作用与参与 NF-B 途径的基因表达降低有关,这表明 ATE 的抗炎作用可能是一种针对胆汁淤积相关肝损伤的潜在机制。我们的研究结果证实了 ATE 作为治疗胆汁淤积性肝损伤和纤维化的替代治疗药物的作用。
