| Research Abstract |
Objectives: The aim of this study was to determine whether or not chemokine BRAK/ CXCL14 transgenic (Tg) mice would show resistance to carcinogenesis, tumor growth and tumor metastasis. Methods: Wild type C57BL/6 (Wt) or Tg mice were injected intraperitoneally with 12 mg/kg body weight azoxymethane followed by intermittent addition of 3 % dextran sodium sulfate in the drinking water. We also injected tumor cells subcutaneously or via a tail vein of the mice. Results: No difference of body weight was observed between Wt and Tg mice but the rate of colorectal cancer was nearly ten times higher (P<0.001) in Wt mice than in Tg ones. Size of transplanted tumors and the number of metastatic foci on the lung of the animals were always significantly lower in the Tg that those in the Wt. Survival rates of the melanoma cell injected Tg mice were significantly higher than those of Wt. Conclusion: The Tg mice showed resistance to carcinogenesis, tumor growth and tumor cell metastasis, indicating BRAK/ CXCL14 has multifunctional effects on tumor suppression.
