Effect of Berberine on HMGB1 Release from Macrophages and its Mechanism / 国际中医中药杂志

ABSTRACT

Objective To study the effect of berberine on extracellular release of high mobility group box 1 (HMGB1) and its mechanism. Methods After LPS was activated by different concentration of berberine, the release of HMGB 1 and TNF-a, and expression of HMGB 1 mRNA in cultured mouse peritoneal macrophages was investigated. Results Berberine markedly suppressed the release of HMGB 1 and expression of HMGB 1 mRNA from LPS-stimulated macrophages (P<0.05). While the release ofTNF-a was't significantly affected. Conclusion Berberine suppressed extracellular release of HMGB 1 by decreasing expression of HMGB 1 mRNA.
