Ceramium boydenii belongs to euphorbia humitusa of red algae, and is distributed along the coast of Jeju island. This study was conducted to examine the anti-inflammatory effect and action mechanism of C. boydenii in the human keratinocyte cell line HaCaT. The 80% EtOH extract of C. boydenii inhibits the production of MDC (macrophage derived chemokine), an inflammatory chemokine, induced by IFN-γ and TNF-α in a concentration dependent manner. It also suppressed the phosphorylation and nuclear translocation of STAT1, a key transcription factor in IFN-γ and TNF-α signaling pathway, at the effective concentrations. These results suggest that C. boydenii demonstrates the anti-inflammatory activity via the suppression of STAT1 activation and has the significant value as an anti-inflammatory source.
