Purpose : The fruit of Actinidia polygama has been used in oriental medicine for the treatment of gout, rheumatoid arthritis, and inflammation. Though A. polygama exhibited anti-inflammatory activity in RAW 264.7 cells and carrageenan-induced rat paw edema, the exact mechanism for anti-inflammation was not evaluated yet. In this study, the anti-inflammatory mechanisms of A. polygama ethanol extract (APEE) in lipopolysaccharide (LPS) stimulated RAW 264.7 cells.
Methods : WST-1 assay was applied to analyze the cytotoxic effect of APEE in RAW 264.7 cells. The productions of nitric oxide (NO) and prostaglandin (PG) E2 were analyzed by the Griess reaction and enzyme immunoassay (EIA) assay, respectively. In addition, protein expressions for inducible NO synthase (iNOS) and cyclooxygenase (COX)-2 were measured by Western blot analysis. The activated status of an inflammatory transcription factor, NF-κB, and its upstream signaling molecules, mitogen-activated protein kinases (MAPKs), was also evaluated by Western blot analysis.
Results : As a result, APEE treatment did not exhibit any cytotoxicity until the concentration of 200 ㎍/㎖. APEE treatment significantly inhibited NO and PGE2 productions as well as their enzymes, iNOS and COX-2 in a dose-dependent manner. The inflammatory transcription factor, NF-κB, was also attenuated by APEE treatment. In addition, the phosphorylated status of MAPKs such as extracellular regulated kinase (ERK), c-jun NH2 kinase (JNK), and p38, were significantly diminished by APEE treatment in LPS stimulated RAW 264.7 cells.
Conclusion : Consequently, APEE treatment significantly attenuated the production of inflammatory mediators and their enzyme expressions in LPS-stimulated RAW 264.7 cells. The inflammatory transcription factor, NF-κB, and upstream signaling molecules, MAPKs, were also significantly attenuated by APEE treatment in LPS-activated RAW 264.7 cells. These results indicate that APEE might be a candidate to be utilized as a promising candidate for the treatment of inflammatory disorders.
