| Outline of Final Research Achievements |
We reported that differentiation-inducing factor-1 (DIF-1), synthesized by Dictyostelium discoideum, inhibited proliferation of various tumor cell lines in vitro. However, it remained unexplored whether DIF-1 also inhibits tumor growth in vivo. In the present study, therefore, we examined in-vivo effects of DIF-1 using three cancer models: Mutyh-deficient mice with oxidative stress-induced intestinal tumors and nude mice xenografted with cancer cells, and lung metastasis model mice.
We found that oral administrated DIF-1 significantly suppressed tumor growth in all examined models.
