英文摘要it is known that chitosan oligosaccharides (cos) suppress lps-induced vascular endothelial inflammatory response by mechanism involving nf-kappa b blockade. it remains unknown how cos inhibit nf-kappa b. we provided evidence both in cultured endothelial cells and mouse model supporting a new mechanism. regardless of the endothelial cell types, the lps-induced nf-kappa b-dependent inflammatory gene expression was suppressed by cos, which was associated with reduced nf-kappa b nucleus translocation. lps enhanced o-glcnac modification of nf-kappa b/p65 and activated nf-kappa b pathway, which could be prevented either by sirna knockdown of o-glcnac transferase (ogt) or pretreatment with cos. inhibition of either mitogen-activated protein kinase or superoxide generation abolishes lps-induced nf-kappa b o-glcnacylation. consistently, aortic tissues from lps-treated mice presented enhanced nf-kappa b/p65 o-glcnacylation in association with upregulated gene expression of inflammatory cytokines in vascular tissues; however, pre-administration of cos prevented these responses. in conclusion, cos decreased ogt-dependent o-glcnacylation of nf-kappa b and thereby attenuated lps-induced vascular endothelial inflammatory response.
