Algae is a potential resource with various biological activities. In this study, the anti-inflammatory effect of Grateloupia imbricata Holmes ethanol extract (GIHEE) from red algae was investigated in LPS-induced RAW 264.7 cells. As a result, reduced secretion of pro-inflammatory cytokines [tumor necrosis factors-${\alpha}$, interleukin (IL)-$1{\beta}$, and IL-6] and nitric oxide (NO) was observed in a dose-dependent manner. Expression of nuclear factor-kappaB (NF-${\kappa}B$) as well as inducible NO synthase and cyclooxygenase-2 proteins was reduced by GIHEE, suggesting that the anti-inflammatory activity of GIHEE is related to suppression of NF-${\kappa}B$ signaling pathways. In addition, GIHEE reduced phosphorylation of mitogen-activated protein kinases. These results suggest that GIHEE can be used as a potential anti-inflammatory therapeutic.
