When mice were injected with B16/F10 tumor cells, and co-treated with 3.2 mg/kg (i.e., 10 μmol/kg), three times daily for 14 days, observations 14 days after tumor implantation showed that the phytochemical reduced tumor volume (86%) and weight (83%), and the plasma concentration of the CXCL1, a chemochine associated with the invasive ability of melanoma (42%). The gene discussed is CXCL1; the disease is neoplasm.
