  • Abstract:Introduction:High-mobility group box 1 (HMGB1) is a therapeutic target for sepsis. Glycyrrhizin (GL) is the aglycone of glycyrrhizin derived from licorice. We clarified the anti-inflammatory effects of GL. We explored the anti-HMGB1 effect of GL and elucidated its molecular mechanism, which will be of benefit for sepsis treatment. Methods:We stimulated murine macrophage-like RAW 264.7 cells with lipopolysaccharide (LPS) and LPS + GL, then measured the expression and release of HMGB1. The expression of related signal transduction factors was detected. Results:High-mobility group box 1 was distributed mainly in the nucleus with lower cytoplasmic levels in RAW 264.7 cells before LPS stimulation. After stimulation, cytoplasmic HMGB1 levels increased gradually, whereas in nuclear fluctuation a trend of HMGB1 expression was observed. Significant upregulation of HMGB1 mRNA occurred 12 h after LPS stimulation. Glycyrrhizin prevented the transfer of HMGB1 from the nucleus to the cytoplasm and inhibited upregulation of HMGB1 mRNA induced by LPS. Phospho-p38 mitogen-activated protein kinase and activated activating protein 1 increased significantly 8 h after LPS stimulation. Tumor necrosis factor α and interleukin 6 increased 4 h after LPS stimulation and peaked at 48 h, and HMGB1 increased at 8 h. The Toll-like receptor 4/MD2/nuclear factor κB signaling pathway was activated 4 h after LPS stimulation. Glycyrrhizin inhibited this pathway. Conclusions:Glycyrrhizin inhibited the expression and release of HMGB1 through blocking the p38 mitogen-activated protein kinase/activating protein 1 signaling pathway then inhibited the massive release of tumor necrosis factor α and interleukin 6.
