| Outline of Final Research Achievements |
The main cause of Japanese death is due to the recurrence of cancer, and metastasis. We have previously reported that the rate of carcinogenesis, the growth of tumor transplants and metastasis in CXCL14 over-expressed transgenic (Tg) mouse were significantly lower compared with that for isogenic wild type C57BL/6 (Wt) mice. Here we investigated suppression mechanisms of metastasis by CXCL14 using the pulmonary metastasis system of the malignant melanoma cell and the cell culture system. It was found that CXCL14 and interferon-γ (IFN-γ) secreted by the activated natural killer (NK)T cells, and also IFN-γ secreted by activated natural killer cells synergistically suppressed the metastasis of the cells on the lungs.
