Paul et al., Br J Pharmacol 1995
:
1. In RAW 264.7 macrophages,
lipopolysaccharide (LPS) and gamma-interferon ( IFN gamma ) alone or in combination
stimulated the induction of
nitric oxide synthase ( iNOS ) activity and increased the expression of the 130 kDa isoform of NOS ... 2.
LPS induced
NOS activity was reduced by incubation with CD14 neutralising antibodies and abolished in macrophages deprived of serum ... 4. The protein kinase C inhibitor, Ro-318220, abolished both
LPS- and IFN gamma stimulated protein kinase C activity and the
induction of
NOS activity ... 8. These results suggest the involvement of protein kinase C, tyrosine kinase and poly-ADP ribosylation pathways in the
regulation of the induction of
nitric oxide synthase in RAW 264.7 macrophages by
LPS and IFN gamma
Park et al., J Neurosci Res 1994
(Glioma) :
LPS induction of
NOS in C6 cells was evidenced by a small amount of nitrite accumulation as compared with cells exposed to IL-1 beta/IFN-gamma, but the maximal NOS activity achieved ( as revealed by cGMP formation ) was the same ... The
NOS activity
induced by
LPS in C6 cells was maximal at 4 to 8 hr and then rapidly decreased, while NOS activity induced by IL-1 beta/IFN-gamma slowly decreased after 4 hr
McKenna et al., Shock 1994
:
LPS and beta-PDB
induced a sustained translocation of PKC activity from the cytosol to the membrane, an increased protein synthesis dependent expression of
nitric oxide synthase (NOS) activity, and an impaired contractility that could be partially reversed by treatment with the NOS inhibitor N omega-nitro-L-arginine methyl ester ... These data indicate that PKC plays a role as an intracellular mediator of
LPS induced
NOS activity and vascular suppression
Hamilton et al., J Clin Invest 1995
:
The cooperative
effects of IFN gamma and
LPS on the expression of the inducible
nitric oxide synthase gene were suppressed by oxidized LDL while the antagonistic effect of IFN gamma on LPS induced expression of the TNF receptor type II mRNA was not altered
Parker et al., Shock 1994
(Toxemia) :
Since L-NAME unmasked a vasoconstrictor action of the endogenous purinoceptor agonist ADP, pharmacologic agents that inhibit NOS may exacerbate
LPS induced inhibition of endothelial
NOS ; this series of events could lead to diminution of vasodilator reserves and perhaps to augmentation of platelet aggregation during Gram negative sepsis
Wang et al., Biochem Biophys Res Commun 1995
:
In view of studies showing that not only
nitric oxide synthase (NOS) activity but arginase activity is

Loegering et al., Life Sci 1995

The present study evaluated the ability of the antioxidant, diethyldithiocarbamate ( DDTC ), to attenuate the

LPS stimulated induction of
NOS in vascular smooth muscle and may thereby ameliorate the impairment of vascular reactivity

:
In these cells, the presence of norepinephrine ( NE ) caused a dose dependent inhibition of the
LPS induction of
NOS activity, with an IC50 value of 100 nM and significant suppression at 100 pM ... In contrast to astroglial cultures,
LPS induction of
NOS activity in RAW 264.7 macrophage cells was not affected by NE or dibutyryl cyclic AMP
Goureau et al., Proc Natl Acad Sci U S A 1993
:
Transforming growth factor beta 1 slightly increases the production of nitrite, an oxidation product of NO, induced by LPS plus IFN-gamma, whereas acidic and basic FGFs markedly inhibit the nitrite release due to LPS/IFN-gamma in a concentration dependent manner, and epidermal growth factor did not modify
LPS/IFN-gamma induced
NOS activity ... Results with heparin, suramin, and tyrphostin suggest involvement of the high-affinity receptor for FGF in its inhibition of
LPS/IFN-gamma stimulated
NOS activity

LPS is a potent
inducer of
mac-NOS in Swiss 3T3 cells but can not induce TIS10/PGS-2
Lowenstein et al., Proc Natl Acad Sci U S A 1993
:
Region I contains LPS related responsive elements, including a binding site for nuclear factor interleukin 6 ( NF-IL6 ) and the kappa B binding site for NF-kappa B, suggesting that this region regulates
LPS induced expression of the
mac-NOS gene ... Region II contains motifs for binding IFN related transcription factors and thus probably is responsible for IFN mediated regulation of
LPS induced
mac-NOS

LPS and IFN-gamma, and declined with time after addition of the inducing agents
Romero et al., Am J Physiol 1996
:
Although IL-1 beta and TNF-alpha are themselves capable of inducing NO synthase (NOS) in glia, the specific factors mediating
LPS induction of
NOS in brain have not been identified ... To determine whether
LPS induction of
NOS in brain cells is mediated by IL-1 or TNF-alpha, acting alone or in concert, the effects of IL-1-receptor antagonist (IL-1Ra) and of TNF-soluble receptor ( TNFsRp55 ), presented individually and in combination, on LPS induced NOS activity were tested ... The results indicate that
LPS induction of
NOS activity in brain cells is mediated in part by both IL-1 beta and TNF-alpha
Kitamura et al., J Neurosci Res 1996

Weisbrodt et al., Am J Physiol 1996
:
This study was designed to determine if an increase in
nitric oxide synthase (NOS) activity
induced by
lipopolysaccharide (LPS) is associated with increases in NOS II protein and mRNA abundance and with altered ileal longitudinal muscle contractility ... These data confirm the reported
effects of
LPS on intestinal
NOS activity and indicate that it can be attributed, at least in part, to an increase in NOS II mRNA and protein abundance

We have examined the role of Stat1alpha in the
induction by
LPS of the mouse inducible
nitric oxide synthase ( EC 1.14.13.39 ) gene ... Collectively, these results show that LPS induced IFN-alphabeta production, Stat1alpha activation, and nitrite accumulation closely parallel one another, suggesting that indirect activation of transcription factor Stat1alpha by IFN-alphabeta is a critical determinant of
LPS mediated inducible
nitric oxide synthase gene expression
