Polygalacic acid (0-100 μM; 24 hours) significantly decreases the mRNAexpressions of MMP-3, MMP-9, MMP-13, and COX-2, which are significantly increased by IL-1β, in a dose-dependent manner. Polygalacic acid (0-100 μM; 6 hours) decreases the expression of phosphor-p38, phosphor-Erk, and phosphor-Jnk induced by IL-1β, phosphor-p65 is not reduced by polygalacic acid.
