Nitric oxide (NO·) produced by inducible nitric oxide synthase (iNOS)
mediates a number of important physiological and pathophysiological processes. The objective of this investigation was to examine the role
of mitogen-activated protein kinases (MAPKs) in the regulation of iNOS
and NO· by interferon-
(IFN-
) + lipopolysaccharide (LPS) in macrophages using specific inhibitors and dominant inhibitory mutant
proteins of the MAPK pathways. The signaling pathway utilized by
IFN-
in iNOS induction is well elucidated. To study signaling pathways that are restricted to the LPS-signaling arm, we used a
subclone of the parental RAW 264.7 cell line that is unresponsive to
IFN-
alone with respect to iNOS induction. In this RAW
264.7
NO(
) subclone, IFN-
and LPS are nevertheless required for
synergistic activation of the iNOS promoter. We found that
extracellular signal-regulated kinase (ERK) augmented and
p38mapk inhibited IFN-
+ LPS induction
of iNOS. Dominant-negative MAPK kinase-4 inhibited iNOS promoter
activation by IFN-
+ LPS, also implicating the c-Jun
NH2-terminal kinase (JNK) pathway in mediating iNOS
induction. Inhibition of the ERK pathway markedly reduced IFN-
+ LPS-induced tumor necrosis factor-
protein expression, providing a
possible mechanism by which ERK augments iNOS expression. The
inhibitory effect of p38mapk appears more
complex and may be due to the ability of p38mapk
to inhibit LPS-induced JNK activation. These results indicate that the
MAPKs are important regulators of iNOS-NO· expression by IFN-
+ LPS.
