Moreover, GP-B1 not only significantly inhibited the growth of cancer cells, but also improved cellular immune response by increasing levels of tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin-10 (IL-10) and interleukin-12 (IL-12) observed in the serum of melanoma-B16-bearing mice [88]. The gene discussed is IL10; the disease is melanoma.
