Nitric Oxide Synthase Type II
Nitric Oxide Synthase
Fatty Acid Synthase, Type II
The form of fatty acid synthase complex found in BACTERIA; FUNGI; and PLANTS. Catalytic steps are like the animal form but the protein structure is different with dissociated enzymes encoded by separate genes. It is a target of some ANTI-INFECTIVE AGENTS which result in disruption of the CELL MEMBRANE and CELL WALL.
A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.

Nitric Oxide Donors
A diverse group of agents, with unique chemical structures and biochemical requirements, which generate NITRIC OXIDE. These compounds have been used in the treatment of cardiovascular diseases and the management of acute myocardial infarction, acute and chronic congestive heart failure, and surgical control of blood pressure. (Adv Pharmacol 1995;34:361-81)
Salts of nitrous acid or compounds containing the group NO2-. The inorganic nitrites of the type MNO2 (where M=metal) are all insoluble, except the alkali nitrites. The organic nitrites may be isomeric, but not identical with the corresponding nitro compounds. (Grant & Hackh's Chemical Dictionary, 5th ed)
Guanosine cyclic 3',5'-(hydrogen phosphate). A guanine nucleotide containing one phosphate group which is esterified to the sugar moiety in both the 3'- and 5'-positions. It is a cellular regulatory agent and has been described as a second messenger. Its levels increase in response to a variety of hormones, including acetylcholine, insulin, and oxytocin and it has been found to activate specific protein kinases. (From Merck Index, 11th ed)
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed)
Dose-Response Relationship, Drug
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
Gene Expression Regulation, Enzymologic
The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS. (from The Dictionary of Cell Biology, Lackie and Dow, 3rd ed.)
Highly reactive compounds produced when oxygen is reduced by a single electron. In biological systems, they may be generated during the normal catalytic function of a number of enzymes and during the oxidation of hemoglobin to METHEMOGLOBIN. In living organisms, SUPEROXIDE DISMUTASE protects the cell from the deleterious effects of superoxides.
Disease Models, Animal
Highly specialized EPITHELIAL CELLS that line the HEART; BLOOD VESSELS; and lymph vessels, forming the ENDOTHELIUM. They are polygonal in shape and joined together by TIGHT JUNCTIONS. The tight junctions allow for variable permeability to specific macromolecules that are transported across the endothelial layer.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.
Tumor Necrosis Factor-alpha
Serum glycoprotein produced by activated MACROPHAGES and other mammalian MONONUCLEAR LEUKOCYTES. It has necrotizing activity against tumor cell lines and increases ability to reject tumor transplants. Also known as TNF-alpha, it is only 30% homologous to TNF-beta (LYMPHOTOXIN), but they share TNF RECEPTORS.
Glycogen Synthase Kinase 3
A soluble factor produced by MONOCYTES; MACROPHAGES, and other cells which activates T-lymphocytes and potentiates their response to mitogens or antigens. Interleukin-1 is a general term refers to either of the two distinct proteins, INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The biological effects of IL-1 include the ability to replace macrophage requirements for T-cell activation.
Collagen Type II
The external reproductive organ of males. It is composed of a mass of erectile tissue enclosed in three cylindrical fibrous compartments. Two of the three compartments, the corpus cavernosa, are placed side-by-side along the upper part of the organ. The third compartment below, the corpus spongiosum, houses the urethra.
Reverse Transcriptase Polymerase Chain Reaction
Reactive Oxygen Species
Molecules or ions formed by the incomplete one-electron reduction of oxygen. These reactive oxygen intermediates include SINGLET OXYGEN; SUPEROXIDES; PEROXIDES; HYDROXYL RADICAL; and HYPOCHLOROUS ACID. They contribute to the microbicidal activity of PHAGOCYTES, regulation of signal transduction and gene expression, and the oxidative damage to NUCLEIC ACIDS; PROTEINS; and LIPIDS.
(GTP cyclohydrolase I) or GTP 7,8-8,9-dihydrolase (pyrophosphate-forming) (GTP cyclohydrolase II). An enzyme group that hydrolyzes the imidazole ring of GTP, releasing carbon-8 as formate. Two C-N bonds are hydrolyzed and the pentase unit is isomerized. This is the first step in the synthesis of folic acid from GTP. EC 18.104.22.168 (GTP cyclohydrolase I) and EC 22.214.171.124 (GTP cyclohydrolase II).
A photographic fixative used also in the manufacture of resins. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), this substance may reasonably be anticipated to be a carcinogen (Merck Index, 9th ed). Many of its derivatives are ANTITHYROID AGENTS and/or FREE RADICAL SCAVENGERS.

Reactive Nitrogen Species
Inducible NO synthase: role in cellular signalling. (1/5912)The discovery of endothelium-derived relaxing factor and its identification as nitric oxide (NO) was one of the most exciting discoveries of biomedical research in the 1980s. Besides its potent vasodilatory effects, NO was found under certain circumstances to be responsible for the killing of microorganisms and tumour cells by activated macrophages and to act as a novel, unconventional type of neurotransmitter. In 1992, Science picked NO as the 'Molecule of the Year', and over the past years NO has become established as a universal intercellular messenger that acutely affects important signalling pathways and, on a more long-term scale, modulates gene expression in target cells. These actions will form the focus of the present review. (+info)
Phenotype of mice and macrophages deficient in both phagocyte oxidase and inducible nitric oxide synthase. (2/5912)The two genetically established antimicrobial mechanisms of macrophages are production of reactive oxygen intermediates by phagocyte oxidase (phox) and reactive nitrogen intermediates by inducible nitric oxide synthase (NOS2). Mice doubly deficient in both enzymes (gp91(phox-/-)/NOS2(-/-)) formed massive abscesses containing commensal organisms, mostly enteric bacteria, even when reared under specific pathogen-free conditions with antibiotics. Neither parental strain showed such infections. Thus, phox and NOS2 appear to compensate for each other's deficiency in providing resistance to indigenous bacteria, and no other pathway does so fully. Macrophages from gp91(phox-/-)/NOS2(-/-) mice could not kill virulent Listeria. Their killing of S. typhimurium, E. coli, and attenuated Listeria was markedly diminished but demonstrable, establishing the existence of a mechanism of macrophage antibacterial activity independent of phox and NOS2.

Role of nitric oxide in lipopolysaccharide-induced hepatic injury in D-galactosamine-sensitized mice as an experimental endotoxic shock model. (3/5912)The role of nitric oxide (NO) in lipopolysaccharide (LPS)-induced hepatic injury was studied in D-galactosamine (D-GalN)-sensitized mice. The inducible isoform of NO synthase (iNOS) was immunohistochemically detected on hepatocytes around blood vessels in livers of mice injected with D-GalN and LPS not on hepatocytes in mice injected with D-GalN or LPS alone, although mRNA for iNOS was found in those mice. Nitrotyrosine (NT) was also found in livers of mice injected with D-GalN and LPS. The localization of NT was consistent with that of iNOS, and the time courses of NT and iNOS expression were almost the same. Expression of iNOS and NT was detected exclusively in the hepatic lesions of mice injected with D-GalN and LPS. Anti-tumor necrosis factor alpha neutralizing antibody inhibited iNOS and NT expression and hepatic injury. The results suggested that NO from iNOS may play a role in LPS-induced hepatic injury on D-GalN-sensitized mice as an experimental endotoxic shock model. (+info)
Gamma interferon stimulates rat alveolar macrophages to kill Pneumocystis carinii by L-arginine- and tumor necrosis factor-dependent mechanisms. (4/5912)Pneumocystis carinii pneumonia remains a serious complication for immunocompromised patients. In the present study, P. carinii organisms interacted with gamma interferon (IFN-gamma)-stimulated alveolar macrophages (AMs) to activate the L-arginine-dependent cytocidal pathway involving reactive nitrogen intermediates (RNI) that were assayed as nitrite (NO2-). Unstimulated cultures of AMs produced negligible quantities of RNI. Addition of P. carinii organisms to IFN-gamma-primed AMs resulted in greatly enhanced production of RNI. NO2- levels increased from 0.8 +/- 0.4 to 11.1 +/- 3.8 microM as early as 6 h after P. carinii organisms were incubated with IFN-gamma-stimulated AMs and to 35.1 +/- 8.9 microM after a 24-h incubation, a near-maximum level. High levels of NO2- were produced by AMs primed with as little as 10 U of IFN-gamma per ml in the presence of P. carinii, and a 20-fold increase in IFN-gamma concentration resulted in only a further 65% increase in NO2- production. RNI-dependent killing of P. carinii was demonstrated by both a 51Cr release assay and a [35S]methionine pulse immunoprecipitation assay. Addition of either monoclonal tumor necrosis factor alpha (TNF-alpha) neutralizing antibody or 200 microM NG-monomethyl-L-arginine (L-NGMMA), a competitive inhibitor of the L-arginine-dependent pathway, significantly decreased NO2- production and reduced P. carinii killing. TNF-alpha alone had no effect on P. carinii viability. These results suggest that (i) the specific interaction of P. carinii organisms with IFN-gamma-primed AMs triggers the production of RNI, (ii) RNI are toxic to P. carinii, and (iii) TNF-alpha likely plays a central role in mediating P. carinii killing by IFN-gamma-stimulated AMs. (+info)
Effect of transforming growth factor beta on experimental Salmonella typhimurium infection in mice. (5/5912)We have investigated the effect of the in vivo administration of recombinant transforming growth factor beta (rTGF-beta) on the pathogenic mechanisms involved in Salmonella typhimurium experimental infection in mice. The protective response elicited by macrophages was induced by rTGF-beta1 by 2 days after experimental infection, as demonstrated by an increased NO production, while the humoral protective effect began with cytokine mRNA expression 2 days after the challenge and continued after 5 days with cytokine release and lymphocyte activation. We demonstrated that all mice who received rTGF-beta1 survived 7 days after infection. The number of bacteria recovered in the spleens and in the livers of rTGF-beta1-treated mice 2 and 5 days after infection was significantly smaller than that found in the same organs after phosphate-buffered saline (PBS) inoculation. Furthermore, 2 and 5 days after infection, splenic macrophages from rTGF-beta1-treated mice showed a greater NO production than did those from PBS-treated mice. The effect of rTGF-beta1 on S. typhimurium infection in mice was correlated with the expression of cell costimulatory CD28 molecules. Five days after S. typhimurium infection, the percentage of CD28(+)-expressing T cells in splenic lymphocytes from rTGF-beta1-treated mice increased with respect to that from control mice. Gamma interferon (IFN-gamma) mRNA was present in a greater amount in spleen cells from rTGF-beta1-treated mice after 2 days, although the intensity of the band decreased 5 days after the challenge. A similar pattern was obtained with the mRNAs for interleukin-1alpha (IL-1alpha), IL-6, TGF-beta, and inducible nitric oxide synthase, which showed greater expression in cells obtained from rTGF-beta1-treated and S. typhimurium-infected mice 2 days after challenge. The treatment with rTGF-beta1 induced an increase in IL-1alpha and IFN-gamma release in the supernatant of splenocyte cultures 5 days after the experimental infection with S. typhimurium. Moreover, we demonstrated that 5 days after infection, the IFN-gamma titer was significantly greater in the sera of rTGF-beta-treated mice than in those of PBS-treated mice. Also, hsp60 showed greater expression 2 days after the challenge in splenocytes from rTGF-beta1-treated mice. The role played by proinflammatory and immunoregulatory cytokines and by CD28 is discussed. (+info)
Nitric oxide in the endometrium. (6/5912)Nitric oxide (NO) is an important mediator of paracrine interactions, especially within the vascular system. It is a powerful inhibitor of platelet aggregation and a potent vasodilator. NO is also a neurotransmitter and it plays a role in cell-mediated cytotoxicity. NO-generating enzymes (nitric oxide synthases, NOS) have been described in the endometrium of a number of species, suggesting that NO might be involved in endometrial function. In human endometrium, endothelial NOS and inducible NOS have been localized to glandular epithelium in the non-pregnant uterus. Weak inducible NOS immunoreactivity has been observed in decidualized stromal cells. NO might participate in the initiation and control of menstrual bleeding. Furthermore, it may play a part in the inhibition of platelet aggregation within the endometrium, where menstrual haemostasis is thought to occur primarily by vasoconstriction rather than clot organization. Endometrially derived NO could also suppress myometrial contractility. Recent attention has focused on the part that NO might play in maintaining myometrial quiescence during pregnancy. NO also appears to relax the non-pregnant myometrium, an action which could be exploited for the medical treatment of primary dysmenorrhoea. (+info)
The cerebral metabolic consequences of nitric oxide synthase deficiency: glucose utilization in endothelial and neuronal nitric oxide synthase null mice. (7/5912)Nitric oxide has multiple physiologic roles in the CNS. Inhibiting nitric oxide synthesis might therefore alter functional activity within the brain. We used [14C]-2-deoxyglucose in vivo autoradiography to measure local CMRglc in "knockout" mice lacking the genes for either the endothelial (eNOS) or neuronal (nNOS) isoforms of nitric oxide synthase, and in the progenitor strains (SV129, C57B1/6). Glucose utilization levels did not significantly differ between nNOS and eNOS knockout mice and C57B1/6 mice in any of the 48 brain regions examined, but were relatively lower in some subcortical regions in SV129 mice.

Impairment of neocortical long-term potentiation in mice deficient of endothelial nitric oxide synthase. (8/5912)The role of the possible retrograde messenger nitric oxide (NO) in the induction of long-term potentiation (LTP) was studied in supragranular layers of somatosensory cortical slices obtained from adult mice. High-frequency stimulation produced a slowly rising, long-lasting (50 min) and significant (P < 0.001) increase in the extracellular synaptic response by 23%. The induction of LTP was independent from activation of N-methyl-D-aspartate (NMDA) receptors, but prevented by bath application of NG-nitro-L-arginine methyl ester (L-NAME), indicating that one or several of the different NO synthases (NOS) produced NO within the postsynaptic neuron. No LTP could be induced in knockout mice lacking the endothelial NOS (eNOS) isoform. These data suggest that eNOS is involved in an NMDA receptor-independent form of LTP in the rodent cerebral cortex. (+info)

Impaired Wound Healing In Corneal Stroma Of A Nitric Oxide Synthase Type II -deficient Mouse | IOVS | ARVO Journals
Purpose: To investigate the effects of loss of nitric oxide synthase type II (NOS2) in the healing of an injured corneal stroma in mice. Cell culture experiments were also conducted to clarify the effects of lacking NOS2 on ocular fibroblast gene expression.. Methods: The effect of lacking NOS2 on corneal stroma wound healing following an incision injury was evaluated by using NOS2-null (KO) mice. Histological, immunohistochemical and mRNA expression analyses were performed. Ocular fibroblasts from wild type (WT) and KO mice were used to study the role of NOS2 on fibrogenic gene expression.. Results: Healing of an incision injury in corneal stroma was delayed with less invasion of macrophages and reduction in expression of aSMA and fibronectin in a KO mouse as compared with a WT mouse. In vitro experiments showed that the loss of NOS2 suppressed mRNA expression of TGFb1 and collagen Ia1, but not MCP-1, in ocular fibroblasts. Being inconsistent with the in vivo finding, lacking NOS2 upregulated ...
High nitric oxide production, secondary to inducible nitric oxide synthase expression, is essential for regulation of the...
Chronic inflammation is a leading cause of neoplastic transformation in many human cancers and especially in colon cancer (CC), in part due to tumour promotion by nitric oxide (NO) generated at inflammatory sites. It has also been suggested that high NO synthesis, secondary to inducible NO synthase (iNOS) expression, is a distinctive feature of cancer stem cells (CSCs), a small subset of tumour cells with self-renewal capacity. In this study we explored the contribution of NO to the development of colon CSC features and evaluated potential strategies to treat CC by modulating NO production. Our data show an integral role for endogenous NO and iNOS activity in the biology of colon CSCs. Indeed, colon CSCs with high endogenous NO production (NO(high)) displayed higher tumourigenic abilities than NO(low) fractions. The blockade of endogenous NO availability, using either a specific iNOS inhibitor or a genetic knock-down of iNOS, resulted in a significant reduction of colon CSC tumourigenic ...

The study arose from an observation that rapamycin inhibited the LPS-induced increase in octamer-binding factor-2 (Oct-2) protein levels through a mammalian target of rapamycin (mTOR)-dependent pathway in mouse RAW264.7 macrophages. As both iNOS and G-CSF are potential Oct-2 target genes, we tested the effect of rapamycin on their expression and found that it reduced the LPS-induced increase in iNOS and ...

Adjuvant Immunotherapy Is Dependent on Inducible Nitric Oxide Synthase | Journal of Experimental Medicine | Rockefeller...
These studies support the hypothesis that the protective effects of CFA preimmunization require functional NOS2. CFA-preimmunized NOS2 knockout mice fail to be protected from the development of EAE. Wild-type mice protected by CFA demonstrate several alterations in their immune response to MOG that may be relevant to the mechanism of protection. The augmentation of anti-MOG IgG1 titers is likely an epiphenomenon rather than responsible for disease protection, as antibodies are not major effector mechanisms of disease in the MOG peptide model of EAE 26. It is interesting that NOD mice treated with CFA demonstrate an augmented IgG1 response to GAD67, consistent with our observation 27. The NO-dependent inhibition of IL-6 production with CFA treatment is highly significant. IL-6-deficient mice are entirely resistant to MOG-induced EAE 28,29,30. Furthermore, the mice that have been genetically modified to overexpress IL-6 in the CNS develop EAE spontaneously 31. The mechanism by which NO inhibits ...
Adjuvant Immunotherapy Is Dependent on Inducible Nitric Oxide Synthase | JEM
Exposure to CFA can impair the subsequent expression of autoimmune disease in small rodents. This observation, also referred to as adjuvant immunotherapy, was first described over 40 years ago and found to be dependent on the presence of Mycobacterium tuberculosis within the adjuvant (1). This immunoprotective effect of CFA has been subsequently demonstrated in multiple autoimmune disease models, both spontaneous and induced, and in multiple species, including rats (2)(3)(4)(5), mice (6), and guinea pigs (1)(7)(8). In each case, preimmunization with CFA alone 21-40 d before attempted disease induction by immunization resulted in a decreased incidence and severity of disease (1)(2)(3)(7)(8).. Much of our current understanding of the CFA effect is derived from rodent models of spontaneous autoimmune diabetes mellitus. A single injection of CFA into nonobese diabetic (NOD) mice between the ages of 4 and 12 wk prevents the development of clinical diabetes indefinitely and extends NOD life span ...

Periadventitial Inducible Nitric Oxide Synthase Expression and Intimal Thickening | Arteriosclerosis, Thrombosis, and Vascular...
Annoying problems with the specificity of iNOS immunostains have recently been reported.22 The main conclusion was that it is essential to include appropriate controls for the species studied, and if possible, to confirm the immunostaining by another technique such as RT-PCR. Hence, we carefully controlled our iNOS immunostains by using appropriate negative (naïve rabbit carotid artery and omission of the primary antibody) and positive controls as well as RT-PCR.. Previously, the presence of iNOS in the intimal thickening induced by a periarterial collar in the rabbit carotid artery had been reported.13 In that study, a rabbit polyclonal iNOS antiserum (primary antibody) and a donkey anti-rabbit IgG-peroxidase (secondary antibody) were used. However, we found that omitting the primary antibody yielded an identical result. Inthe absence of the primary antibody, the immunoreactivity in the intima can be explained by reaction of the secondary antibody with IgG that has infiltrated into the intima ...

Microbiology Society Journals | Mice lacking inducible nitric-oxide synthase are more susceptible to herpes simplex virus...
Mice deficient in the inducible nitric-oxide synthase (iNOS), constructed by gene-targeting, were significantly more susceptible to herpes simplex virus (HSV)-1 infection, displayed a delayed clearance of virus from the dorsal root ganglia (DRG) and exhibited an increase in the frequency of virus reactivation in DRG compared with similarly infected heterozygous mice. The infected iNOS-deficient mice developed enhanced Th1-type immune responses and their spleen cells produced higher concentrations of IL-12 than similarly infected heterozygous mice. This finding suggests that iNOS plays an important role in resistance against HSV-1 infection. Furthermore, nitric oxide (NO) may block the development of Th1 cells via inhibition of IL-12 synthesis and thereby play a role in immune regulation.

BACKGROUND: Duchenne muscular dystrophy (DMD) is the most common, lethal disease of childhood. One of 3500 new-born males suffers from this universally-lethal disease. Other than the use of corticosteroids, little is available to affect the relentless progress of the disease, leading many families to use dietary supplements in hopes of reducing the progression or severity of muscle wasting. Arginine is commonly used as a dietary supplement and its use has been reported to have beneficial effects following short-term administration to mdx mice, a genetic model of DMD ...

TY - JOUR. T1 - Prevention of nitric oxide synthase induction in vascular smooth muscle cells by microtubule depolymerizing agents. AU - Marczin, Nándor. AU - Papapetropoulos, Andreas. AU - Jilling, Tamás. AU - Catravas, John D.. PY - 1993/1/1. Y1 - 1993/1/1. N2 - We investigated the role of microtubules in the induction of nitric oxide synthase in cultured vascular smooth muscle cells. We found that like interleukin‐1α, lipopolysaccharide elicited a time and concentration‐dependent accumulation of cyclic GMP via induction of nitric oxide synthase. Nocodazole and colchicine, two chemically distinct microtubule depolymerizing agents, completely prevented lipopolysaccharide‐ and interleukin‐induced (and nitric oxide‐mediated) cyclic GMP generation. In contrast to lipopolysaccharide and interleukin‐1α, cyclic GMP accumulation in response to sodium nitroprusside, an exogenous nitrovasodilator, was not altered by either nocodazole or colchicine. Our findings demonstrate that ...
IJMS | Free Full-Text | Pu-erh Tea Reduces Nitric Oxide Levels in Rats by Inhibiting Inducible Nitric Oxide Synthase Expression...
Pu-erh tea undergoes a unique fermentation process and contains theabrownins, polysaccharides and caffeine; although it is unclear about which component is associated with the down regulation of nitric oxide levels or how this process is mediated. To address this question we examined the effects of pu-erh tea on nitric oxide synthase (NOS) genes. Cohorts of rats were separately given four-week treatments of water as control, pu-erh tea, or the tea components: theabrownins, caffeine or polysaccharides. Five experimental groups were injected with lipopolysaccharides (LPS) to induce nitric oxide (NO) production, while the corresponding five control groups were injected with saline as a negative control. The serum and liver NO concentrations were examined and the NOS expression of both mRNA and protein was measured in liver. The results showed that the rats which were fed pu-erh tea or polysaccharides had lower levels of NO which corresponded with the down-regulation of inducible nitric oxide synthase (iNOS

The aim of this study was to investigate the role of inducible nitric oxide synthase (iNOS) in gentamicin-induced acute tubular necrosis in rats using the iNOS inhibitor L-N6-(1-iminoethyl) lysine (L-NIL). Wistar rats, both sexes (n=18), were equally divided into three groups. Gentamicin group received intraperitoneally (i.p.) gentamicin in 0,9 % NaCl at a dose of 80 mg/kg/day for five consecutive days. L-NIL+gentamicin group received L-NIL at a dose of 3mg/kg i.p. 36, 24 and 12 h before first dose of gentamicin. Control group received 0,9 % NaCl i.p. for five consecutive days at the equal volume as gentamicin group. Griess reaction was used for determination plasma level of NO. Semiquantitative histological analysis was used for the evaluation of kidney damage level. The plasma NO level and the level of kidney damage were statistically higher in gentamicin group in comparison to the control group (p=0,046). Application of L-NIL prior to gentamicin led to certain decrease in the plasma level of ...

TY - JOUR. T1 - The Oct DNA motif participates in the alcohol inhibition of the inducible nitric oxide synthase gene promoter in rat C6 glioma cells. AU - Sanchez, Alma C.. AU - Davis, Randall L.. AU - Syapin, Peter J.. PY - 2007/11/7. Y1 - 2007/11/7. N2 - Induction of nitric oxide synthase-2 (iNOS) by cytokines and bacterial products is associated with protein binding at the proximal promoter and in an upstream enhancer region of the Nos2 gene. To clarify how ethanol suppresses rat iNOS activity, we constructed several deletion mutants of the Nos2 promoter fused to the luciferase gene and transfected the constructs into C6 glial cells. Acute ethanol exposure of stably transfected cells for 24 h inhibits induced activity of Nos2 promoter constructs containing deletions in the 5′ flanking region, including a 94 bp promoter that lacks any known NF-κB site but which carries a C/EBPβ and overlapping γ-IRE, GAS and Oct motifs. Ethanol failed to inhibit the endogenous activity of a smaller, 78 bp ...
Chamomile: An anti-inflammatory agent inhibits inducible nitric oxide synthase expression by blocking RelA/p65 activity
Chamomile has long been used in traditional medicine for the treatment of inflammation-related disorders. In this study we investigated the inhibitory effects of chamomile on nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression, and explored its potential anti-inflammatory mechanisms using RAW 264.7 macrophages. Chamomile treatment inhibited LPS-induced NO production and significantly blocked IL-1β, IL-6 and TNFα-induced NO levels in RAW 264.7 macrophages. Chamomile caused reduction in LPS-induced iNOS mRNA and protein expression. In RAW 264.7 macrophages, LPS-induced DNA binding activity of RelA/p65 was significantly inhibited by chamomile, an effect that was mediated through the inhibition of IKKβ, the upstream kinase regulating NF-κB/Rel activity, and degradation of inhibitory factor-κB. These results demonstrate that chamomile inhibits NO production and iNOS gene expression by inhibiting RelA/p65 activation and supports the utilization of chamomile as an ...

TY - JOUR. T1 - Myeloperoxidase up-regulates the catalytic activity of inducible nitric oxide synthase by preventing nitric oxide feedback inhibition. AU - Galijasevic, Semira. AU - Saed, Ghassan M.. AU - Diamond, Michael P.. AU - Abu-Soud, Husam M.. PY - 2003/12/9. Y1 - 2003/12/9. N2 - Kinetic and structure analysis of inducible nitric oxide synthase (iNOS) revealed that, in addition to the increase of iNOS expression in inflamed areas, the major pathway causing overproduction of NO is destabilization of the iNOS-nitrosyl complex(es) that form during steady-state catalysis. Formation of such a complex allows iNOS to operate at only a fraction (20-30%) of its maximum activity. Thus, bioavailability of NO scavengers at sites of inflammation may play an essential role in up-regulation of the catalytic activity of iNOS, by preventing the catalytic activity inhibition that is attributed to nitrosyl complex formation. Myeloperoxidase (MPO), a major NO scavenger, is a pivotal enzyme involved in ...
Lirias: Expression of the inducible isoform of nitric oxide synthase in the retinas of human subjects with diabetes mellitus
PURPOSE: Inducible nitric oxide synthase has been implicated in the pathogenesis of cerebral ischemic damage, in the angiogenic process and in diabetic vascular damage. This study was undertaken to determine whether inducible nitric oxide synthase is present in the retinas from human subjects with diabetes mellitus. METHODS: This was an experimental immunohistochemical prospective study. Ten postmortem eyes from five subjects with diabetes mellitus, 10 eyes from five subjects without diabetes and without known ocular disease, and two eyes from one subject with unilateral ocular ischemic syndrome secondary to severe carotid artery obstruction were examined. We used immunohistochemical techniques and antibodies directed against inducible nitric oxide synthase, glial fibrillary acidic protein, and vimentin. The main outcome measure was immunoreactivity for these antibodies. RESULTS: Immunoreactivity for inducible nitric oxide synthase was not observed in retinas from all subjects without diabetes ...

J Interferon Cytokine Res. 2015 Sep 29. [Epub ahead of print]. Interferon-γ-Induced Nitric Oxide Synthase-2 Contributes to Blood/Brain Barrier Dysfunction and Acute Mortality in Experimental Streptococcus pneumoniaeMeningitis.. Yau B1, Mitchell AJ1,2, Too LK1, Ball HJ1, Hunt NH1.. Author information. Abstract. The proinflammatory cytokine interferon-gamma (IFNγ) recently was shown to play a crucial role in experimental pneumococcal meningitis (PM) pathogenesis, and we aimed in this study to investigate IFNγ-driven nitric oxide synthase-2 (NOS2)-mediated pathogenesis of murine PM. We demonstrate that costimulation of toll-like receptors and IFNγ receptors was synergistic for NOS2 expression in cultured murine microglia. Using an experimental PM model, wild-type mice treated with anti-IFNγ antibody, as well as IFNγ and NOS2 gene knockout (GKO) mice, were inoculated intracerebroventricularly with 103 colony-forming units of Streptococcus pneumoniae (WU2 strain). Mice were monitored daily ...
The role of inducible nitric oxide synthase in macrophage activation following acute lung injury
DescriptionMacrophage origin and activity is complex in response to acute lung injury. Inducible nitric oxide synthase (iNOS) has a divergent role in the stages following intratracheal bleomycin mediated lung injury (ITB). We hypothesize iNOS is necessary for macrophage activation during the inflammatory and resolution phases that follow ITB. Further, recruited macrophages classically activate during inflammation and resident macrophages alternatively activate during resolution. To test these hypotheses, iNOS was manipulated via scavenge of products, systemic selective iNOS inhibition and chimeric mice in which particular populations were NOS2-/-. C57/BL6 mice were intratracheally instilled with bleomycin and samples collected 8 and 15 days following instillation. This work identified oxidants to promote inflammation during the early stages following ITB. Systemic iNOS inhibition reduced classical activation of recruited macrophages during inflammation and alternative activation of recruited ...
High inducible nitric oxide synthase in prostate tumor epithelium is associated with lethal prostate cancer
OBJECTIVE: The aim of this study was to investigate the role of inducible nitric oxide synthase (iNOS) in lethal prostate cancer (PCa) by studying the iNOS immunoreactivity in tumor tissue from men diagnosed with localized PCa.. MATERIALS AND METHODS: This study is nested within a cohort of men diagnosed with incidental PCa undergoing transurethral resection of the prostate (the Swedish Watchful Waiting Cohort). To investigate molecular determinants of lethal PCa, men who died from PCa (n = 132) were selected as cases; controls (n = 168) comprised men with PCa who survived for at least 10 years without dying from PCa during follow-up. The immunoreactivity of iNOS in prostate tumor epithelial cells and in cells of the surrounding stroma was scored as low/negative, moderate or high. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for lethal PCa according to iNOS category.. RESULTS: There was no association between iNOS immunoreactivity in stroma ...

The present study was performed to investigate the effects of chronic administration of nonylphenol (NP) on the expression of inflammation-related genes in the brains of mice. NP was given orally by gavages at 0, 50, 100, and 200 mg/kg/d. The expression of inflammatory enzymes, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), was evaluated by immunohistochemistry and immunoblotting assays. The nitric oxide (NO) level and nitric oxide synthase (NOS) activity were also measured by biochemical analyses. The results showed that NP at a high dose (200 mg/kg/d) significantly increased the expression of iNOS and COX-2 in both the hippocampus and cortex. In parallel with the increase in iNOS expression, the NO level was significantly greater at the dose of 200 mg/kg/d, compared to the control. The activity of NOS was also increased in the brain of mice at the dose of 100 and 200 mg/kg/d. These findings demonstrate that NP may have the potential to induce the chronic inflammation or cause
Effect of 17-? Estradiol on the Expression of Inducible Nitric oxide Synthase in Parent and Tamoxifen Resistant T47D Breast...
Indirect evidence suggests that estrogen is involved in the etiology of breast cancer. Estrogen is also thought to modulate nitric oxide (NO) in human breast tumor tissue via regulation of inducible nitric oxide synthase (iNOS). Objectives of this study were to determine whether estradiol (E2) affects iNOS expression level in breast cancer cells and to study the effect of various concentrations of E2 on cell proliferation. Immunocytochemical technique was employed to assess iNOS expression level. Proliferation of parent and 10-6 M tamoxifen resistant cells (T47D/TAMR-6) were assessed by MTT assay in the presence of E2. Addition of E2 (10-12 to 10-8 M) increases the expression of iNOS in parent cells, but not T47D/TAMR-6, Further increase in concentrations of E2 (10-8 to 10-4 M) again decreases the expression of iNOS in parent cells, but increase that of the T47D/TAMR-6 cells. Expression of iNOS in parent cells in a medium containing 1% serum (low serum) is less than the cells grown in a medium

Infection with Helicobacter pylori is recognized as a primary factor in the etiology of gastric disease and its early pathogenic effects are manifested by up-regulation in proinflammatory cytokine release, enhancement in nitric oxide generation, and amplification of apoptotic events. We applied the animal model of H. pylori -induced gastritis to study the effect of a specific inhibitor of p38 mitogen-activated protein kinase (p38 MAPK), SB 203580, on the mucosal apoptotic processes, and the expression of inducible nitric oxide synthase (NOS-2) activity and soluble tumor necrosis factor-α (TNF-α). Groups of rats were pretreated intragastrically with SB 203580 (5, 10, and 20 mg/kg) or vehicle, followed 60 min later by intragastric application of H. pylori lipopolysaccharide at 50 μg/animal, and after 2 and 4 additional days on the twice daily regimen of SB 203580 or vehicle, the animals were killed and their gastric mucosal tissue subjected to histologic and biochemical assessment. In the absence of SB

In this work, we have analyzed the effect of IFN-α/β on the expression of iNOS in macrophages activated with suboptimal concentrations of LPS and IFN-γ, a model in which cooperation between these two factors is well known (2, 3, 4, 5, 6). However, the data regarding the effect of type I IFNs on iNOS transcription are rather controversial: IFN-α/β is induced and secreted by macrophages after triggering with IFN-γ, LPS, or combinations of both, and the kinetics of the process are well known (15, 27, 28). Challenge of the murine macrophage cell line J774 with LPS induces the synthesis of IFN-α/β after 3 h of treatment (27), a time at which we have observed that the addition of IFN-α/β has minimal effects on the expression of iNOS. Moreover, if the culture medium is depleted of IFN-α/β with a neutralizing Ab, the synthesis of NO markedly decreases, indicating that type I IFNs might participate in an autocrine loop intended to maintain iNOS levels in LPS-activated J774 cells. However, ...

NF-κB is a ubiquitous dimeric transcription factor that exists in the cytosol complexed to an inhibitory κB (IκB) monomer. NF-κB complexes consist most commonly of p50/p65 dimers.26,27 Various stimuli activate NF-κB, leading to its translocation to the nucleus, where it binds to specific DNA binding sites, called κB, present within the promoter region of various genes including COX-2.27 Activation of NF-κB is controlled by site-specific phosphorylation and ubiquitination of IκB proteins.26 Among the known IκB proteins, IκBα and IκBβ have been studied most extensively and are thought to be the key regulators of NF-κB nuclear translocation. Phosphorylation of serine residues at positions 32 and 36 is critical for the ubiquitination and degradation of IκBα.16,28,29. Pharmacological studies have implicated NF-κB as a necessary transcription factor in the development of late PC.1,3,12,30 Unequivocal assessment of the functional contribution of NF-κB to this process, however, has ...

Here we demonstrated that aging increased iNOS expression, leading to insulin resistance in the skeletal muscle through the S-nitrosation mechanism. Genetic, pharmacological, and physiological iNOS inhibition reduced IRβ, IRS-1, and Akt S-nitrosation and increased insulin signaling in old mice. Our results reinforce the idea that iNOS plays a crucial role in inducing insulin resistance, as previously shown in different animal models such as diet-, lipopolysaccharide-, and lipid-induced skeletal muscle insulin resistance (3,13,15,16).. In contrast to our data, Cha et al. (17) reported that iNOS deficiency does not prevent age-associated insulin resistance. In contrast to the previous study, we did not observe an increase in TNF-α expression in the skeletal muscle of aged iNOS-null mice compared with the aged wild-type group; these data were confirmed by analyzing IKKβ phosphorylation. In accordance with our data, a previous study showed iNOS knockout mice were protected from insulin resistance ...
Transdifferentiation Requires iNOS Activation: Role of RING1A S-Nitrosylation | Circulation Research
Rationale: We have previously shown that innate immunity is necessary for transdifferentiation of fibroblasts to endothelial cells. A major signaling molecule involved in innate immunity is inducible nitric oxide synthase (iNOS). Accordingly, we hypothesized that iNOS-generated nitric oxide (NO) might enhance transdifferentiation. Objective: To elucidate the role of NO in epigenetic plasticity during transdifferentiation. Methods and Results: We exposed the BJ fibroblasts to transdifferentiation formulation that included endothelial growth factors and innate immune activator polyinosinic:polycytidylic acid (PIC) to induce endothelial cells (iECs). Generation of iECs was associated with iNOS expression and NO elaboration. In absence of PIC, or in presence of antagonists of NFκB or iNOS activity, NO synthesis and iEC generation was reduced. Furthermore, genetic knockout (in MEFs) or siRNA knockdown (in BJ fibroblasts) of iNOS nearly abolished transdifferentiation, an effect which could be ...

M. avium TMC724 (originally obtained from the Trudeau Institute) was passaged in C57BL/6 mice and cultured in Middlebrook 7H9 (Difco) medium supplemented with oleic acid, albumin, dextrose, and catalase (Becton Dickinson) to a late logarithmic phase. Aliquots were frozen at -70°C until needed. An inoculum of bacteria was prepared by thawing several aliquots, washing them by centrifugation at 16,000 g for 15 min, and pooling the pellets in distilled water. Aerogenic infection was performed in a Glas-Col aerosol infection device (Glas-Col). Mice were exposed for 40 min to an aerosol generated by nebulizing ∼5.5 ml of a suspension containing 109 CFU/ml M. avium TMC724. Inoculum size (∼105 CFU/lung) was checked 24 h after infection by determining the bacterial load in the lungs of infected mice. Mice were scored as moribund and killed when weight loss was in excess of 30% compared with age-matched uninfected controls.
