Background: Curcumin is a natural phytochemical polyphenol with significant anti-cancer effects and negligible side effects. In this study, the therapeutic capacity of nanomicellar-curcumin for treating lung metastasis was evaluated in an immunocompetent mouse model of metastatic melanoma. Martials and methods: Two doses of nanomicellar-curcumin (i.e. 10 and 20 mu M) were used to induce cytotoxicity in 3 melanoma cell lines. A total of 60 mice were allocated to 20 mice in each of three groups (10 for survival and 10 for assays). Groups were no treatment control, PBS control, nanomicellar-curcumin 20 mg/kg IP 4 times a week, for three weeks). Immunohistochemistry, TUNEL assay, and Western blots were used on lung samples. Results: Nanomicellar-curcumin inhibited the in vitro growth of B16 F10 melanoma cells at 20 mu M over 72 h. In vivo, 20 mg/kg nanomicellar-curcumin injected IP, delayed tumor cell growth and significantly extended mouse survival rate. Tumor infiltration of regulatory T cells and angiogenesis were reduced, while IFN-gamma and CXCL10 were increased. Conclusion: Nanomicellar-curcumin can inhibit lung metastasis and growing melanoma via activation of apoptosis, activated T cells and inhibition of angiogenesis, tumor growth and regulatory T cells.
