Title: Diosmin suppresses the proinflammatory mediators in lipopolysaccharide-induced RAW264.7 macrophages via NF-κB and MAPKs signal pathways
Author: Mehmet Berköz

Abstract: Diosmin is an unsaturated flavonoid glycoside, presents in citrus fruits. The aim of this study is to investigate the molecular mechanism of diosmin with respect to the NF-κB and MAPKs signaling pathways. Firstly, 10, 20, 30, 40 and 50 µM diosmin were treated to lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. The anti-inflammatory effects of diosmin was displayed via measuring prostaglandin E2 (PGE2), nitric oxide (NO), interleukines (IL-6, IL-12), tumor necrosis factor α (TNF-α) production, cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), IL-6, IL-12, TNF-α mRNA levels, and phosphorylation levels of nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor alpha (IκB-α) and mitogen-activated protein kinases (MAPKs); JNK, ERK, and p38 in LPS induced RAW264.7 macrophages. Our study showed that especially high concentrations of diosmin decreased NO, PGE2, IL-6, IL-12, TNF-α production and mRNA levels of these mediators (p
