Calystegia soldanella is distributed in coastal sand dunes and has high environmental adaptability; it is also known to be effective for anti-oxidant, anti-pyretic, anti-septic, and diuretic action. This study investigated the effect of crude extracts and organic solvent fractions of C. soldanella on MMP-2 and MMP-9 expression, MMP activity, and cell mobility in phorbol-12-myristate-13-acetate (PMA)-induced fibrosarcoma HT-1080 cells. C. soldanella was twice extracted, once with methylene chloride (MC) and once with methanol (MeOH). After the MC and MeOH extracts were combined, their suppressive effects on MMP-2 and MMP-9 expression, MMP enzymatic activity, and gene and protein expression were measured by gelatin zymography, enzyme-linked immunosorbent assay, reverse-transcription polymerase chain reaction, and western blot method. Cell mobility for the HT-1080 cells was observed by wound healing assay. The combined crude extracts showed a significant suppressive effects on MMP-2 and MMP-9 expression. To explore active inhibitory elements, the combined extracts were fractionated according to polarity into with n-hexane, 85% aqueous methanol, n-butanol, and water. Across these four solvent fractions, MMP-2 and MMP-9 activity and cell mobility in the HT-1080 cells were all strongly inhibited by the n-hexane fraction. These results suggest that C. soldanella extract and organic solvent fractions could be used as potent MMP inhibitors for effective anti-cancer treatments to suppress cancer invasion and metastasis.
