Anluohuaxianwan Alleviates Carbon Tetrachloride-Induced Hepatic Fibrosis in Rats through Upregulation of Peroxisome Proliferator-Activated Receptor-Gamma and Downregulation of Nuclear Factor-Kappa B/IκBα Signaling Pathway

摘要

Objective:The aim of this study was to investigate the effects of traditional Chinese medicine Anluohuaxianwan（ALHXW）on peroxisome proliferator-activated receptor-gamma（PPARγ）and nuclear factor-kappa B（NF-κB）signaling pathways using a rat model of carbon model groups were gavaged with saline for 6 weeks.Liver function was measured,and liver fibrosis and necroinflammation were assessed.Protein and messenger RNA expression levels of PPARγ,NF-κB,and Inhibitorαof NF-κB（IκBα）were analyzed by Western blot and reverse transcription–quantitative polymerase chain reaction.Results:ALHXW markedly alleviated liver injury compared with the model group,as indicated by the improvements in disease status,the morphology of liver and spleen,the liver and spleen indexes,and liver function.The extent of liver fibrosis was improved,hepatic stellate cell activation was inhibited,the expression of PPARγand IκBαwas significantly higher,and the expression of NF-κB was significantly lower in the treatment group as compared with the model group.Conclusions:ALHXW treatment can alleviate CCl4-induced liver fibrosis in rats, and the potential antifibrogenic mechanisms may occur through the upregulation of PPARγ expression and downregulation of NF-κB/IκBα signaling pathway.
