We found that a concentration of greater than 0.5 ng/mL of IL-6, 0.1 ng/mL of IL-12, and 1 ng/mL of IFN-γ dramatically suppressed B16F10 cell proliferation, whereas those cytokines had minimal effects on MMT, mammary tumor cells, and 3LL, which are lung carcinoma cells (Figure 3). The gene discussed is IFNG; the disease is breast cancer.
