What is Green chicory leaf extract exerts anti-inflammatory effects through suppressing LPS-induced MAPK/NF-κB activation and hepatoprotective activity in vitro about?

Green chicory (Cichorium intybus) leaf is consumed worldwide that has tremendous bio-functional activities. This study was designed to elucidate the bio-functional activities of the green chicory leaf extract (CLE). Trolox equivalent antioxidant activities were carried out against DPPH, ABTS radical scavenging and ferric reducing activities. CLE showed remarkable hepatoprotective activity against oxidative damages and reactive oxygen species reducing effect in RAW 264.7 and Hep G2 cells. The anti-inflammatory effects performed on LPS-induced RAW 264.7 cells and primary spleen cells. In RAW 264.7 cells, Chicory leaf extract significantly restored the iNOS, COX-2, IL-6, TNF-α and other pro-inflammatory cytokines in mRNA expression. Meanwhile, it restored NF-κB (P-65) and MAPK pathways activation in immunoblot assay dose-dependently and repressed the P-65 translocation in the nucleus. Moreover, it showed notable anti-proliferative activities and downregulated NF-κB (P-65) and MAPK activation in LPS-stimulated splenocytes. Our findings suggest that CLE could be used as a natural anti-inflammatory agent.
