Hepatoprotective effects of Gamisoyo-san against acetaminophen-induced liver injuries.

ABSTRACT:

Background

Acetaminophen (N-acetyl-p-aminophenol, APAP) is a safe and effective analgesic at therapeutic dosage. However, APAP overdose is a major cause of acute liver injury. Gamisoyo-san (GMSYS; Jiaweixiaoyao-san in Chinese, Kamishoyo-san in Japanese), a traditional herbal formula, is used to treat phlegm and cough in Korea. The purpose of this study was to investigate the hepatoprotective effect of GMSYS against APAP-induced liver injury in vitro and in vivo.

Methods

We evaluated the effect of GMSYS on APAP-induced hepatotoxicity by measuring cell viability in murine BNL CL.2 liver cells. Additionally, BALB/c mice were orally administered with GMSYS once daily for 7 days. Eighteen hours after the last administration, mice were intraperitoneally injected with 200 mg/kg APAP. Plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, hepatic antioxidants, and histological changes were examined.

Results

Pretreatment with GMSYS attenuated the decrease in cell viability induced by APAP in BNL CL.2 cells. In mice, pre-administration with GMSYS alleviated APAP-induced hepatotoxicity by decreasing plasma ALT and AST activities and hepatic malondialdehyde, and by increasing the total glutathione (GSH)/reduced GSH ratio and the activities of several antioxidants such as superoxide dismutase, catalase, GSH peroxidase, GSH reductase, GSH-S-transferase, and heme oxygenase-1.

Conclusion

GMSYS has a protective effect against APAP-induced acute liver injury by decreasing plasma transaminases and increasing antioxidants. GMSYS may be an effective candidate for the prevention of acute liver injury.

Project description:Acetaminophen (APAP) overdose still poses a major clinical challenge and is a leading cause of acute liver injury (ALI). N-acetylcysteine (NAC) is the only approved antidote to treat APAP toxicity while NAC therapy can trigger side effects including severe vomiting and even shock. Thus, new insights in developing novel therapeutic drugs may pave the way for better treatment of APAP poisoning. Previous research has reported that nuciferine (Nuci) possesses anti-inflammatory and antioxidant properties. Therefore, the objective of this study was proposed to investigate the hepatoprotective effects of Nuci and explore its underlying mechanisms. Mice were intraperitoneally (i.p.) administered with APAP (300 mg/kg) and subsequently injected with Nuci (25, 50, and 100 mg/kg, i.p.) at 30 min after APAP overdose. Then, all mice were sacrificed at 12 h after APAP challenge for further analysis. Nuci-treated mice did not show any side effects and our results revealed that treating Nuci significantly attenuated APAP-induced ALI, as confirmed by histopathological examinations, biochemical analysis, and diminished hepatic oxidative stress and inflammation. The in silico prediction and mRNA-sequencing analysis were performed to explore the underlying mechanisms of Nuci. GO and KEGG enrichment of the predicted target proteins of Nuci includes reactive oxygen species, drug metabolism of cytochrome P450 (CYP450) enzymes, and autophagy. Furthermore, the mRNA-sequencing analyses indicated that Nuci can regulate glutathione metabolic processes and anti-inflammatory responses. Consistently, we found that Nuci increased the hepatic glutathione restoration but decreased APAP protein adducts in damaged livers. Western blot analysis further confirmed that Nuci effectively promoted hepatic autophagy in APAP-treated mice. However, Nuci could not affect the expression levels of the main CYP450 enzymes (CYP1A2, CYP2E1, and CYP3A11). These results demonstrated that Nuci may be a potential therapeutic drug for APAP-induced ALI via amelioration of the inflammatory response and oxidative stress, regulation of APAP metabolism, and activation of autophagy.
