Endotoxin is dramatically increased in portal venous blood after serious injury and can contribute to liver damage. However, the mechanism underlying endotoxin\u2019s effects on HSCs remains largely unknown. Oridonin is a bioactive diterpenoid isolated from<jats:italic> Rabdosia rubescens<\/jats:italic> that exhibits anti-inflammatory properties in different tissues. In the present study, we determined the effects of oridonin on endotoxin-induced inflammatory response and signaling pathways<jats:italic> in vitro.<\/jats:italic> The production of proinflammatory cytokines in activated human HSCs line LX-2 was measured by ELISA and Western blots. Immunofluorescence and nuclear fractionation assay were used to determine NF-<jats:italic>\u03ba<\/jats:italic>B activity<jats:italic>. <\/jats:italic>Oridonin treatment significantly inhibited LPS-induced proinflammatory cytokines IL-1<jats:italic>\u03b2<\/jats:italic>, IL-6, and MCP-1 production as well as cell adhesion molecules ICAM-1 and VCAM-1. Additionally, oridonin blocked LPS-induced NF-<jats:italic>\u03ba<\/jats:italic>B p65 nuclear translocation and DNA binding activity. Oridonin prevented LPS-stimulated NF-<jats:italic>\u03ba<\/jats:italic>B regulator IKK<jats:italic>\u03b1<\/jats:italic>\/<jats:italic>\u03b2<\/jats:italic> and I<jats:italic>\u03ba<\/jats:italic>B<jats:italic>\u03b1<\/jats:italic> phosphorylation and I<jats:italic>\u03ba<\/jats:italic>B<jats:italic>\u03b1<\/jats:italic> degradation. Combined treatment of oridonin and an Hsp70 substrate binding inhibitor synergistically suppressed LPS-stimulated proinflammatory cytokines and NF-<jats:italic>\u03ba<\/jats:italic>B pathway activation. Therefore, oridonin inhibits LPS-stimulated proinflammatory mediators through IKK\/I<jats:italic>\u03ba<\/jats:italic>B<jats:italic>\u03b1<\/jats:italic>\/NF-<jats:italic>\u03ba<\/jats:italic>B pathway.
