The Citrus Flavone Nobiletin Reduces Pro-Inflammatory and Pro-Labour Mediators in Fetal Membranes and Myometrium: Implications for Preterm Birth
Figure 6
Effect of nobiletin on pro-inflammatory cytokines in preterm fetal membranes.
Preterm fetal membranes with histological chorioamnionitis and following spontaneous preterm labour were incubated for 20 h with or without 200 µM nobiletin (n = 9 patients). (A–D) TNF-α, IL-1β, IL-6 and IL-8 mRNA expression was analysed by qRT-PCR and normalised to GAPDH mRNA expression. The fold change was calculated relative to basal expression, which was set at 1. Data is displayed as mean ± SEM (one-way ANOVA). *P<0.05 vs. basal expression. (E, F) The incubation medium was assayed for concentration of IL-6 and IL-8 by ELISA. Data was normalised to untreated (basal) levels, which was set at 1. Each bar represents mean ± SEM (one-way ANOVA). *P<0.05 vs. basal release.
