Abstract

Cholestasis is caused by intrahepatic retention of excessive toxic bile acids and ultimately results in hepatic failure. Da-Chai-Hu-Tang (DCHT) has been used in China to treat liver and gallbladder diseases for over 1800 years. Here, we demonstrated that DCHT treatment prevented acute intrahepatic cholestasis with liver injury in response to α-naphthylisothiocyanate (ANIT) not to bile duct ligation (BDL) induced-extrahepatic cholestasis. ANIT (80 mg/kg) increased serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), direct bilirubin (DBiL), total bilirubin (TBiL), and total bile acids (TBA) which was attenuated by DCHT treatment in a dose-dependent manner. DCHT treatment at high dose of 1.875 g/kg restored bile acid homeostasis, as evidenced by the recovery of the transcription of genes implicated in bile acid biosynthesis, uptake and efflux. DCHT treatment (1.875 g/kg) reversed ANIT-evoked disordered glutathione homeostasis (as determined by GSH/GSSG ratio) and increased in the mRNA levels for , and associated with liver inflammation. Using network pharmacology-based approaches, we identified 22 putative targets involved in DCHT treatment for intrahepatic cholestasis not extrahepatic cholestasis. In addition, as evidenced by dual-luciferase reporter assays, compounds from DCHT with high affinity of PPARα increased luciferase levels from a PPARα-driven reporter. PPARα agonist fenofibrate was able to mimic the cytoprotective effect of DCHT on intrahepatic cholestasis, which was abolished by the PPARα antagonist GW6471. KEGG enrichment and western blot analyses showed that signaling axes of JNK/IL-6/NF-κB/STAT3 related to PPARα might be the principal pathway DCHT affects intrahepatic cholestasis. Taken together, the present study provides compelling evidence that DCHT is a promising formula against acute intrahepatic cholestasis with hepatotoxicity which works PPARα activation.

摘要

胆汁淤积是由肝内过多毒性胆汁酸潴留引起的,最终会导致肝衰竭。大柴胡汤(DCHT)在中国用于治疗肝胆疾病已有1800多年的历史。在此,我们证明DCHT治疗可预防α-萘异硫氰酸酯(ANIT)诱导而非胆管结扎(BDL)诱导的肝外胆汁淤积所致的伴有肝损伤的急性肝内胆汁淤积。ANIT(80mg/kg)可使血清丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、直接胆红素(DBiL)、总胆红素(TBiL)和总胆汁酸(TBA)水平升高,而DCHT治疗可呈剂量依赖性地减弱这种升高。高剂量1.875g/kg的DCHT治疗可恢复胆汁酸稳态,这可通过参与胆汁酸生物合成、摄取和流出的基因转录的恢复得以证明。DCHT治疗(1.875g/kg)可逆转ANIT诱发的谷胱甘肽稳态紊乱(通过GSH/GSSG比值测定),并使与肝脏炎症相关的、和的mRNA水平升高。使用基于网络药理学的方法,我们确定了22个可能参与DCHT治疗肝内胆汁淤积而非肝外胆汁淤积的靶点。此外,双荧光素酶报告基因检测表明,DCHT中与PPARα具有高亲和力的化合物可提高PPARα驱动的报告基因的荧光素酶水平。PPARα激动剂非诺贝特能够模拟DCHT对肝内胆汁淤积的细胞保护作用,而PPARα拮抗剂GW6471可消除这种作用。KEGG富集和蛋白质印迹分析表明,与PPARα相关的JNK/IL-6/NF-κB/STAT3信号轴可能是DCHT影响肝内胆汁淤积的主要途径。综上所述,本研究提供了令人信服的证据,表明DCHT是一种有前景的针对伴有肝毒性的急性肝内胆汁淤积的方剂,其作用机制是激活PPARα。
