摘要
In this letter,we comment on a recent publication by Mei et al,in the World Journal of Hepatology,investigating the hepatoprotective effects of the modified Xiaoyao San(MXS)formula in a male rat model of non-alcoholic steatohepatitis(NASH).The authors found that MXS treatment mitigated hepatic steatosis and inflam-mation in the NASH model,as evidenced by the reduction in lipid droplets(LDs),fibrosis markers and lipogenic factors.Interestingly,these hepatoprotective effects were associated with androgen upregulation(based on metabolomics analysis of male steroid hormone metabolites),adenosine 5’-monophosphate-activated protein kinase(AMPK)activation,and restoration of phosphatase and tensin homolog(PTEN)expression.However,the authors did not clearly discuss the relationships between MXS-induced hepatic steatosis reduction in the NASH model,and androgen upregulation,AMPK activation,and restoration of PTEN expression.This editorial emphasizes the reported mechanisms and explains how they act or interact with each other to reduce hepatic steatosis and inflammation in the NASH model.As a perspective,we propose additional mechanisms(such as autophagy/lipophagy activation in hepatocytes)for the clearance of LDs and suppression of hepatic steatosis by MXS in the NASH model.A proper understanding of the mechanisms of MXS-induced reduction of hepatic steatosis might help in the treatment of NASH and related diseases.
