Abstract:
Schisandrol B (SolB) is one of the active constituents from a traditional Chinese medicine Schisandra chinensis or Schisandra sphenanthera. Our previous studies found that SolB exerts hepatoprotective effects against drug-induced liver injury and promotes liver regeneration. We further found that SolB significantly induces liver enlargement but the mechanisms remain unclear. The purpose of this study was to investigate the change of lipidome in liver tissues during SolB-induced hepatomegaly. The animal experiment protocol was approved by the Institutional Animal Care and Use Committee at Sun Yat-sen University. Serum and liver samples of male C57BL/6 mice were collected after intraperitoneal injection of SolB (100 mg·kg-1·d-1) for 5 days. Lipidomics analysis was performed using Q Exactive UHPLC-MS/MS system. The results showed that SolB significantly promoted liver enlargement in mice without liver injury and inflammation. Lipid accumulation was observed in the liver tissues after SolB treatment. Thirty-five lipids were identified with significant change and triglycerides (TG) were found to have the most significant increase in SolB-treated group, indicating the increase of energy production during SolB-induced hepatomegaly. This study reveals the impact of SolB on lipid metabolism and provides a potential explanation for liver enlargement induced by SolB.
