Laetiporus sulphrueus var. miniatus is widely distributed worldwide, and has commonly been used as a medicinal mushroom. In the present study, we investigated the effects of water extract and solvent fractions from the Laetiporus miniatus as possible antioxidant, anti-thrombin and anti-invasive agents against phorbol 12-myristate 13-acetate (PMA)- or thrombin-induced matrix metalloproteinase-2 (MMP-2) and MMP-9 activities. Samples were fractionated into n-hexane, $CHCl_3$, ethyl acetate, n-butanol, and water fractions, and individually analysed. The water fraction had the highest extraction yield at 34.90% (w/w), while the n-butanol fraction demonstrated the highest anti-oxidative activity at 81.44%. In the thrombin inhibitory activity test, the water fraction exhibited the highest activity at 94.64%. Even at the concentration of $40{\mu}g/mL$, evaluation of anti-proliferating activity in YD-10B cells did not reveal any cytotoxic effects. Although MMP-9 expression in YD-10B cells increased after the addition of PMA and thrombin, MMP-2 did not. Additionally, MMP-2/-9 levels in PMA-treated YD-10B cells (i.e., both mRNA expression and protein activation) were highly inhibited in the hexane and chloroform fractions. Compared with MMP-2 levels, MMP-9 mRNA expression and proteolytic activity were inhibited to a greater extent by the hexane and chloroform fractions in thrombin-treated YD-10B cells. Taken together, these results support that thrombin induces tumor invasion through MMP-2/9 and suggest that the L. miniatus may act as an effective functional food, conferring anti-oxidative, anti-thrombotic and anti-cancer activities.
