Outline of Final Research Achievements |
First, we demonstrated that orally administered Clopidogrel, a P2Y12 receptor antagonist, inhibited lung metastasis in mice intravenously injected with B16-BL6 mouse melanoma cells. To elucidate the mechanism of antimetastatic action of P2Y12 receptor antagonists, the effects of Clopidogrel and Ticlopidine on cell motility and invasiveness were measured by chemotaxis assay and chemoinvasion assay, respectively. Clopidogrel significantly reduced both cell motility and invasiveness in a dose-dependent manner. Ticlopidine also significantly reduced cell motility in a dose-dependent manner. Furthermore, Clopidogrel reduced the protein expression level of Vimentin, while Ticlopidine significantly reduced Matrix metalloproteinase-9 (MMP-9) activity and the protein expression level of MMP-2.
