Abstract:

Liver fibrosis is a pathological manifestation induced by chronic liver injury and may cause cirrhosis and liver cancer with the chronic progression of fibrosis. During the onset and progression of liver fibrosis, the activation of hepatic stellate cells (HSCs) is the core mechanism for the secretion of many extracellular matrices to induce fibrosis. Lignans are reportedly the main effective components of Schisandra chinensis with good anti-fibrosis effects. In this study, we compared the inhibiting effects of the seven lignan components from S. chinensis on HSC activation. We found that the seven lignans inhibited the activation of human HSCs (LX-2) in various degrees. Among all lignans, schisanhenol showed the best effect in inhibiting the activation of LX-2 with a dose-effect relationship. Sal also inhibited the phosphorylations of Smad1, Smad2, Smad3, extracellular regulated protein kinase (ERK), c-Jun N-terminal kinase (JNK), p38, and nuclear transcription factor-κB (NF-κB), as well as downregulated Smad4. All these findings suggested that schisanhenol may ameliorate liver fibrosis by inhibiting the transforming growth factor β (TGF-β)/Smad and mitogen-activated protein kinase (MAPK) signaling pathways. Remarkably, schisanhenol may be a potential anti-liver fibrosis drug and warrants further research.
