Heme oxygenase-1 (HO-1) negatively regulates inflammatory cytokines in lipopolysaccharide (LPS)-activated RAW 264.7 cells. The purpose of the study was to know whether anti-inflammatory effect of the extract of Artemisia capillaries (EAC) is responsible for HO-1 protein expression in RAW264.7 cells. EAC increased HO-1 expression in a time and concentration-dependent manner and inhibited the expression of iNOS (NO) and COX-2 (PGE2), and release of high mobility group box 1 (HMGB1) in LPS…

It is concluded that EP inhibits proinflammatory response to LPS in macrophages and increases survival in CLP-induced septic mice by upregulation of HO-1 level, in which p38 MAPK and Nrf2 play an important role.
β₁-adrenergic receptor-mediated HO-1 induction, via PI3K and p38 MAPK, by isoproterenol in RAW 264.7 cells leads to inhibition of HMGB1 release in LPS-activated RAW 264.7 cells and increases in survival rate of CLP-induced septic mice.

It is shown that LPS induced the endogenous HO-1 gene expression in RAW264.7 monocytic cells and suggests that the NF-kappaB and p38 MAPK signaling pathways mediate the LPS-dependent induction of HO- 1 gene expression via DNA sequences of the proximal promoter region.

It is suggested that 6 h of treatment with LPS increases intracellular cAMP levels via COX-2 induction and prostaglandin E2 production, resulting in PKA activation, NF-κB activation, iNOS expression, and NO production.

It is suggested that YS 49 suppresses iNOS gene expression induced by LPS and/or cytokines in RAVSMC and RAW 264.7 cells, which could therefore be beneficial in septic shock and other diseases associated with iN OS over‐expression.

Exaggerated circulating levels of HMGB1 contribute to endotoxin-induced mortality in the absence of heme oxygenase (HO)-1, which is suggested to contribute to the pathobiology of endotoxemia.
