RhoA inhibition provides a priming signal for IL-1β release. Messenger RNA of THP-1 cells treated with RhoA inhibitor is isolated, and induction of four genes is determined in comparison to untreated control cells. Simvastatin treatment is taken as the broad-ranging prenylation inhibitor. Of the four genes, only IL-1β (A) is significantly up-regulated. The related cytokine IL-18 (B) and the inflammasome components NLRP3 (C) and caspase-1 (D) show no difference. All genes are normalized to GAPDH; bar graphs represent the average of three independent experiments.
