ABSTRACT
BACKGROUND:
Acetaminophen (APAP)-induced hepatotoxicity is a major cause of acute liver failure (ALF), during which autophagy is triggered as a cellular defense mechanism. Shaoyao-Gancao Decoction (SGD), a traditional prescription in Chinese Medicine, is renowned for its therapeutic effects on liver diseases. However, the efficacy and mechanisms of SGD in treating APAP-induced liver injury remain underexplored.PURPOSE:
This study aims to provide robust evidence regarding the protective effects of SGD against APAP overdose in vitro and in vivo, as well as to elucidate its hepatoprotective mechanisms and active components. STUDYDESIGN:
The hepatoprotective mechanisms and active components of SGD were investigated through a combination of in vivo and in vitro experiments.METHODS:
The protective effects of SGD on APAP-induced liver injury were assessed using a murine model and primary hepatocytes. RNA sequencing and subsequent experimental validations were conducted to uncover the underlying mechanisms of SGD's hepatoprotective actions. Comprehensive chemical profiling of SGD was performed using UHPLC-Q-Exactive Orbitrap HRMS to identify potential active ingredients. Immunohistochemistry, immunofluorescence, quantitative real-time PCR (qPCR), western blotting, enzyme-linked immunosorbent assay (ELISA), and flow cytometry were utilized to investigate the specific cellular changes in liver tissues and hepatocytes influenced by SGD.RESULTS:
SGD was observed to mitigate APAP-induced mitochondrial damage, inflammation, and necrosis by promoting mitochondrial autophagy. The inhibition of autophagy negated the hepatoprotective effects of SGD. Additionally, a detailed characterization of SGD's chemical composition revealed that Licoisoflavone B, Liquiritin, Liquiritin apioside, Licorice saponin G2 and Paeoniflorin Sulfit were potentially critical compounds in the regulation of autophagy and mitophagy.CONCLUSION:
Our findings demonstrate that SGD promotes autophagy/mitophagy, which effectively mitigates APAP-induced hepatotoxicity, suggesting SGD's potential as a promising therapeutic agent for APAP-induced liver injury.
