The transcription factor Nrf2 is decreased after spontaneous term labour in human fetal membranes where it exerts anti-inflammatory properties

Abstract

Introduction Inflammation plays a central role in the terminal processes of human labour and delivery, including the rupture of fetal membranes. Recent studies show a role for the transcription factor Nrf2 (NF-E2-related factor 2) in regulating inflammation. The aims of this study were to determine the effect of human spontaneous term and preterm labour on Nrf2 expression in fetal membranes; and Nrf2 siRNA knockdown on pro-inflammatory cytokines.Methods Fetal membranes, from term and preterm, were obtained from non-labouring and labouring women. Primary amnion cells were used to determine the effect of Nrf2 siRNA knockdown on pro-inflammatory cytokines in the presence of inflammation or infe..
