Treatment of EMT‐6 mammary adenocarcinoma cells with gamma interferon (rMuIFNγ) plus tumor necrosis factor (rMuTNFα) and/or interleukin‐1 (rHuIL‐1α) causes release of iron‐55 label, inhibition of DNA replication, and inhibition of aconitase activity. In addition, the same combinations of cytokines induce EMT‐6 cells to synthesize L‐citrulline, nitrite, and nitrate directly from L‐arginine. Lipopolysaccharide (LPS) can act as a cofactor in the induction of these metabolic effects when added to EMT‐6 cells in the presence of rMuIFNγ. The results show that increased levels of cytokines in the microenvironment can induce a novel effector pathway in somatic cells not specialized for host defense, resulting in specific metabolic effects as well as the inhibition of cellular proliferation.
