The antitumor effect of murine recombinant interferon (beta) [Mu-rIFN(beta)] was examined on artificial metastasis of B-16 melanoma in C57BL/6 mice. The numbers of pulmonary nodules were significantly decreased to 16.7 +/- 4.7 (P less than 0.01), 9.5 +/- 4.2 (P less than 0.01), 7.1 +/- 5.6 (P less than 0.01) in mice given 20,000 units of Mu-rIFN(beta) intraperitoneally (ip) 24, 6, and 3 hr before intravenous tumor inoculation, respectively, compared with the control group of mice (57.1 +/- 1.4), if B-16 melanoma cells (5 X 10(5] were intravenously injected 28 days before the experiment. In mice given 20,000 units of Mu-rIFN(beta) ip 24, 6, and 3 hr before the experiment, the natural killer (NK) activities of spleen cells against YAC-1 cells were elevated to 45.5 +/- 6.1%, 53.7 +/- 3.4%, 43.2 +/- 6.5%, respectively, compared with NK activities in control mice (20.3 +/- 3.1%). Similarly, NK activities against B-16 melanoma cells were also elevated in mice given Mu-rIFN(beta). Pretreatment with anti-asialo GM1 antibody and carrageenan reduced the inhibitory effect of Mu-rIFN(beta) on the pulmonary metastasis. In vitro colony inhibition of more than 50% was not observed even if B-16 melanoma cells were incubated with 100,000 units/ml of Mu-rIFN(beta). From these results, it can be concluded that the inhibition of pulmonary metastasis by Mu-rIFN(beta) is mediated via host defense mechanisms and that NK cells and macrophages are both important for the inhibition.
