Abstract:
:The incubation of rat peritoneal macrophages in the presence of staurosporine, a non-specific protein kinase inhibitor, induced interleukin-6 (IL-6) production in a time- and concentration-dependent manner at 6.3-63 nM, but at 210 nM, the stimulant effect on IL-6 production was reduced. The levels of IL-6 mRNA as determined by a reverse transcription-polymerase chain reaction were also increased by staurosporine in parallel with the ability to induce IL-6 production. Compounds structurally related to staurosporine including K-252a (non-specific protein kinase inhibitor) and KT-5720 (inhibitor of cyclic AMP-dependent protein kinase, PKA), did not increase IL-6 production by peritoneal macrophages. Staurosporine-induced increases in IL-6 production and expression of IL-6 mRNA were decreased by the PKC inhibitors, H-7 (2.7-27 microM), Ro 31-8425 (1-10 microM) and calphostin C (0.3-3 microM) and by the phosphatidylinositol 3-kinase (PI 3-kinase) inhibitor LY294002 (30-100 microM), but were further increased by the protein tyrosine kinase (PTK) inhibitor, genistein (12-37 microM). The staurosporine-induced increase in IL-6 production was not affected by the PKA inhibitor, H-89 (0.1-3 microM). These findings suggest that the induction of IL-6 production by staurosporine is secondary to elevation of IL-6 mRNA level, which, in turn, is positively regulated by the activation of PKC and PI 3-kinase and negatively regulated by the activation of PTK. PKA does not appear to play a significant role.
