Advanced glycation endproducts mediate pro-inflammatory actions in human gestational tissues via nuclear factor-κB and extracellular signal-regulated kinase 1/2

Abstract

Processes of human labour include increased oxidative stress, formation of inflammatory mediators (e.g. cytokines) and uterotonic phospholipid metabolites (e.g. prostaglandins). In non-gestational tissues, advanced glycation endproducts (AGE) induce the expression of pro-inflammatory molecules through mitogen-activated protein kinase and nuclear factor κB (NF-κB) -dependent pathways. Thus, the aim of this study was to investigate the effects of AGE on 8-isoprostane (a marker of oxidative stress), pro-inflammatory cytokine and prostaglandin release in human gestational tissues, and to define the signalling pathways involved. Human placenta and gestational membranes (amnion and choriodecidua. ..
