Anti-Inflammatory Effect of the Extracts from Abeliophyllum distichum Nakai in LPS-Stimulated RAW264.7 Cells

DOI : 10.7732/kjpr.2014.27.3.209

In this study, we investigated whether A. distichum decreases the production of inflammatory mediators through downregulation of the NF-κB and ERK pathway. Our data indicated that A. distichum leaf inhibits the overexpression of iNOS in protein and mRNA levels, and subsequently blocked LPS-mediated NO overproduction in RAW264.7 cells. A. distichum leaf inhibited IκB-α degradation and p65 nuclear translocation, and subsequently suppressed transcriptional activity of NF-κB in LPS-stimulated RAW264.7 cells. In addition, A. distichum leaf suppressed LPS-induced ERK1/2 activation by decreasing phosphorylation of ERK1/2. These findings suggest that A. distichum leaf shows anti-inflammatory activities through suppressing ERK-mediated NF-κB activation in mouse macrophage.
