Cytokine-stimulated expression of inducible type of nitric oxide synthase (iNOS) seems to be regulated by various signal pathways in a cell-specific manner. In this study, we examined how it was regulated in L6 rat skeletal muscle cells. In L6 cells, the combination of interleukin-1 beta and interferon-gamma induced a marked accumulation of nitrite, a stable metabolite of nitric oxide. In parallel with this reaction, iNOS mRNA expression was achieved at a maximum between 3 and 6 h, and iNOS protein was detectable at 6 h and peaked at 24 h after stimulation. Tyrosine kinase inhibitors, herbimycin A, and genistein suppressed cytokine-induced iNOS expression and nitrite production. Forskolin, an adenosine 3',5'-cyclic monophosphate-dependent protein kinase (PKA) activator, and phorbol 12-myristate 13-acetate, a protein kinase C (PKC)-activating phorbol ester, enhanced these cytokine-induced reactions. These results indicate that iNOS expression by cytokines is mediated via a protein tyrosine kinase-dependent pathway and is positively modulated by both PKA- and PKC-dependent pathways in this cell type.
