Treatment with Viscum album potencies induces reduction of MCP-1 and ROs levels in murine melanoma cells.

Melanoma is responsible for most skin cancer deaths. It has a high metastatic potential, complex treatment, and a hopeless prognosis. Viscum album extract (Va) is a complementary treatment in cancer, with in vitro and in vivo cytotoxic effects on different tumor types. However, its ultra-diluted homeopathic preparations' effects and mechanisms on cancer cells need further study. Thus, the aim of present work was to investigate cytokine profile and ROs production of melanoma cells after treatment with ultradiluted VA collected from host tree Abies alba (VaAa) and Quercus rubur (VaQr)during Swiss summer. For this, potencies of Va in different homeopathic scales were prepared using mother tincture (MT) from VaAa and VaQr submitted to homeopathic ethanolic maceration and then a subsequent dynamization process. Then, B16F0 melanoma cells cultivated in 24-well plates were treated with MT or 12DH, 200CH or 5LM potencies of VaAa or VaQr for 24, 48 or 72 hours. After these periods, culture supernatants were collected to assess the levels of MCP-1, INF-γ, TNF-α, IL-10, IL-12p70 and IL-6 cytokines and, ROs production. Results demonstrated significant reduction of MCP-1 and ROs levels in B16F10 melanoma cells treated with Va (VaQr, preferentially) at 12DH or 5LM potencies when compared to untreated or carboplatin-treated cells. In conclusion, we demonstrated for the first time, the in vitro effects of Va potencies prepared in different homeopathic scales in relation to cytokines and ROs production in cell melanoma cells.
