description ► Inflammatory cytokines elevate reactive species, 12-LO and induce islet dysfunction. ► NADPH oxidase 1 is induced in islets and beta cell lines by inflammatory cytokines. ► Inhibitors of NADPH oxidase preserve markers of beta cell function. ► 12-LO activates islet NOX-1 and inhibitors of 12-LO block cytokine induced NOX-1. ► Integrated pathway of inflammatory cytokine-induced beta cell dysfunction identified. Elevated cellular reactive species, which can be produced by diabetic serum conditions such as elevated inflammatory cytokines, lipotoxicity or glucotoxicity contribute to islet beta cell dysfunction and cell death. Cellular pathways that result in beta cell oxidative stress are poorly resolved. In this study, stimulation of human donor islets, primary mouse islets or homogeneous beta cell lines with a cocktail of inflammatory cytokines (TNFα, IL-1β, and INFγ) significantly induced NADPH oxidase-1 (NOX-1) gene expression (p

In this study, stimulation of human donor islets, primary mouse islets or homogeneous beta cell lines with a cocktail of inflammatory cytokines (TNFα, IL-1β, and INFγ) significantly induced NADPH oxidase-1 (NOX-1) gene expression (p<0.05). This pro-inflammatory cytokine cocktail concomitantly induced loss of islet glucose stimulated insulin response (p<0.05), elevated expression of MCP-1 (p<0.01), increased cellular reactive oxygen species (ROS) and induced cell death. Inhibitors of NADPH oxidase, apocynin and diphenyleneiodonium, and a dual selective NOX1/4 inhibitor, blocked ROS generation (p<0.01) and induction of MCP-1 (p<0.05) by pro-inflammatory cytokines in beta cells. It has previously been reported that pro-inflammatory cytokine stimulation induces 12-lipoxygenase (12-LO) expression in human islets. 12-Hydroxyeicosatetraenoic acid (12-HETE), a product of 12-LO activity, stimulated NOX-1 expression in human islets (p<0.05). A novel selective inhibitor of 12-LO blocked induction of NOX-1, production of ROS and pro-caspase 3 cleavage by pro-inflammatory cytokines in INS-1 beta cells (p<0.01). Inhibition was not seen with a structurally related but inactive analog. Importantly, islets from human type 2 diabetic donors have an elevated expression of NOX-1 (p<0.05).
