Expression of c-fos mRNA was investigated in fresh, normal peritoneal macrophages (M phi), which are terminally differentiated, nonproliferating cells. The levels of c-fos mRNA were dramatically increased by stimulation with phorbol myristate acetate (PMA), calcium ionophore, or 1-oleoyl-2-acetoyl glycerol (OAG). Induction of c-fos mRNA by all the above agents followed similar kinetics, with a peak of mRNA 30 min after stimulation. These results demonstrate that c-fos mRNA can be augmented in fresh, terminally differentiated cells. Since the stimuli increasing c-fos mRNA are direct or indirect activators of protein kinase C, our data suggest that in M phi c-fos mRNA is controlled by protein kinase C activation. PMA, calcium ionophore, and OAG were biologically active in M phi. PMA and calcium ionophore induced respiratory burst and tumoricidal activity, respectively, whereas OAG and PMA were chemotactic for M phi. Interferons beta and gamma, potent M phi activators eliciting tumoricidal activity, did not alter the levels of c-fos mRNA. These results indicate that c-fos mRNA augmentation is a stimulus-specific rather than a function-specific response connected to activation of protein kinase C.
