Abstract

A number of similarities and dissimilarities in the anti-tumor effects of TNF and interferon α/β have been observed in DBA/2 mice injected with Friend erythroleukemia cells (FLC). Mouse TNF exerted marked anti-tumor effects in mice injected either s.c. or i.p. with FLC lines 3C 18 or 3 γR8 resistant in vitro to the cytotoxic effects of TNF. Likewise, mouse interferon α/β had anti-tumor activity in mice injected with these FLC, resistant to the action of interferon α/β or γ in vitro. The results of histopathologic examination and 31P nuclear magnetic resonance analyses of 3C18 FLC s.c. tumors injected with TNF resembled the results previously obtained for 3C18 FLC tumors injected with interferon α/β, although the effects of TNF occurred more rapidly. Injection of mice with antibody to mouse interferon α/β or γ did not abrogate the anti-tumor effects of TNF in mice injected i.p. with FLC. Our results suggest that in this experimental system the anti-tumor effects of TNF, like interferon α/β, do not result from a direct effect on the tumor cells themselves but are host-mediated.
