Abstract
Dinitrosyl iron complexes (DNICs) are important physiological derivatives of nitric oxide. These complexes have a wide range of biological activities, with antioxidant and antiradical ones being of particular interest and importance. We studied the interaction between DNICs associated with the dipeptide L-carnosine or serum albumin and prooxidants under conditions mimicking oxidative stress. The ligands of these DNICs were histidine residues of carnosine or His39 and Cys34 in bovine serum albumin. Carnosine-bound DNICs reduced the level of piperazine free radicals in the reaction system containing tert-butyl hydroperoxide (t-BOOH), bivalent iron ions, a nitroxyl anion donor (Angeli's salt), and HEPES buffer. The ability of carnosine DNICs to intercept organic free radicals produced from t-BOOH decay could lead to this effect. In addition, carnosine DNICs reacted with the superoxide anion radical (O2•-) formed in the xanthine/xanthine oxidase enzymatic system. They also reduced the oxoferryl form of the heme group formed in the reaction of myoglobin with t-BOOH. DNICs associated with serum albumin were found to be rapidly destroyed in a model system containing metmyoglobin and t-BOOH. At the same time, these protein DNICs inhibited the t-BOOH-induced oxidative degradation of coenzymes Q9 and Q10 in rat myocardial homogenate. The possible mechanisms of the antioxidant and antiradical action of the DNICs studied and their role in the metabolism of reactive oxygen and nitrogen species are discussed.

Abstract
Dinitrosyl iron complexes (DNICs) are a physiological form of nitric oxide (•NO) in an organism. They are able not only to deposit and transport •NO, but are also to act as antioxidant and antiradical agents. However, the mechanics of hemoglobin-bound DNICs (Hb-DNICs) protecting Hb against peroxynitrite-caused, mediated oxidative modification have not yet been scrutinized. Through EPR spectroscopy we show that Hb-DNICs are destroyed under the peroxynitrite action in a dose-dependent manner. At the same time, DNICs inhibit the oxidation of tryptophan and tyrosine residues and formation of carbonyl derivatives. They also prevent the formation of covalent crosslinks between Hb subunits and degradation of a heme group. These effects can arise from the oxoferryl heme form being reduced, and they can be connected with the ability of DNICs to directly intercept peroxynitrite and free radicals, which emerge due to its homolysis. These data show that DNICs may ensure protection from myocardial ischemia.

Abstract
Lipid peroxidation plays a major role in vascular dysfunction and age-related cardiovascular diseases. A major product of lipid peroxidation, tert-butyl hydroperoxide (t-BHP), has been reported to modulate vascular reactivity and cellular signaling. To better understand vascular abnormality, we set out to delineate the activation mechanism of nuclear factor kappa B (NF-kappaB) by t-BHP and the regulation of MAPK in endothelial cells. The results showed that t-BHP induces NF-kappaB activation by an inhibitor of kappaB (IkappaB) phosphorylation through IkappaB kinase (IKK) activation. Our data from this t-BHP study also showed increased p38 MAP kinase and ERK activity; however, interestingly, t-BHP showed no influence on JNK. Pretreatment with the p38 MAP kinase inhibitor, SB203580 and the ERK1/2 inhibitor, PD98059, prevented t-BHP-induced increases in p65 translocation, NF-kappaB luciferase activity, and phospho-IKKalpha/beta. Data suggested that t-BHP induces NF-kappaB activation through the IKK pathway, which involves p38 MAPK and ERK activation. This study illustrates a role of t-BHP in NF-kappaB activation and MAPK related-signaling pathways. The t-BHP-induced activation of NF-kappaB and MAPK could be a major player in vascular dysfunctions, as seen in oxidative stressed responses and the vascular inflammatory process.

Abstract
The increased production of NO during the early stages of apoptosis indicates its potential involvement in the regulation of programmed cell death through yet to be identified mechanisms. Recently, an important role for catalytically competent peroxidase form of pentacoordinate cytochrome c (cyt c) in a complex with a mitochondria-specific phospholipid, cardiolipin (CL), has been demonstrated during execution of the apoptotic program. Because the cyt c.CL complex acts as CL oxygenase and selectively oxidizes CL in apoptotic cells in a reaction dependent on the generation of protein-derived (tyrosyl) radicals, we hypothesized that binding and nitrosylation of cyt c regulates CL oxidation. Here we demonstrate by low temperature electron paramagnetic resonance spectroscopy that CL facilitated interactions of ferro- and ferri-states of cyt c with NO and NO(-), respectively, to yield a mixture of penta- and hexa-coordinate nitrosylated cyt c. In the nitrosylated cyt c.CL complex, NO chemically reacted with H(2)O(2)-activated peroxidase intermediates resulting in their reduction. A dose-dependent quenching of H(2)O(2)-induced protein-derived radicals by NO donors was shown using direct electron paramagnetic resonance measurements as well as immuno-spin trapping with antibodies against protein 5,5-dimethyl-1-pyrroline N-oxide-nitrone adducts. In the presence of NO donors, H(2)O(2)-induced oligomeric forms of cyt c positively stained for 3-nitrotyrosine confirming the reactivity of NO toward tyrosyl radicals of cyt c. Interaction of NO with the cyt c.CL complex inhibited its peroxidase activity with three different substrates: CL, etoposide, and 3,3'-diaminobenzidine. Given the importance of CL oxidation in apoptosis, mass spectrometry analysis was utilized to assess the effects of NO on oxidation of 1,1'2,2'-tertalinoleoyl cardiolipin. NO effectively inhibited 1,1'2,2'-tertalinoleoyl cardiolipin oxidation catalyzed by the peroxidase activity of cyt c. Thus, NO can act as a regulator of peroxidase activity of cyt c.CL complexes.

Abstract
It is hypothesized that oxidative reactions of hemoglobin driven by reactive oxygen species in the vasculature lead to endothelial cell injury or death. Bovine aortic endothelial cells were incubated with diaspirin cross-linked hemoglobin (DBBF-Hb), developed as a hemoglobin-based oxygen carrier, and hydrogen peroxide (H(2)O(2)), generated by the glucose oxidase system. The low steady flux of H(2)O(2) oxidizes the ferrous form of DBBF-Hb and drives the redox cycling of ferric and ferryl DBBF-Hb. Cells underwent rounding, swelling and detachment, and accumulated in the G2/M phase of the cell cycle. G2/M arrest preceded the onset of apoptosis as determined by increases in phosphatidylserine (PS) externalization and sub-G1 events. Redox cycling of unmodified hemoglobin also led to G2/M arrest and apoptosis. The rate and extent of DBBF-Hb oxidation correlated with the onset and extent of G2/M arrest and apoptosis and induced significant decreases in soluble reduced thiols. Earlier depletion of glutathione by pretreatment with buthionine sulfoximine rendered cells more susceptible to G2/M arrest and apoptosis. The caspase inhibitor, z-VAD-fmk, had no effect on the induction of G2/M arrest but completely inhibited the subsequent increases in PS externalization and sub-G1 events. Catalase inhibited DBBF-Hb oxidation, the loss of thiols, and the onset of G2/M arrest and apoptosis. These data support a causative role for the ferric-ferryl redox cycle in the development of endothelial cell injury.

Abstract
Three distinct antioxidant pathways are considered through which iron-catalyzed oxidative stress may be regulated by nitric oxide (NO). The first two pathways involve direct redox interactions of NO with iron catalytic sites and represent a fast response that may be considered an emergency mechanism to protect cells from the consequences of acute and intensive oxidative stress. These are (i) NO-induced nitrosylation at heme and non-heme iron catalytic sites that is capable of directly reducing oxoferryl-associated radicals, (ii) formation of nitrosyl complexes with intracellular "loosely" bound redox-active iron, and (iii) an indirect regulatory pathway that may function as an adaptive mechanism that becomes operational upon long-term exposure of cells to NO. In the latter pathway, NO down-regulates expression of iron-containing proteins to prevent their catalytic prooxidant reactions.

Abstract
The Janus face of nitric oxide (NO) has prompted a debate as to whether NO plays a deleterious or protective role in tissue injury. There are a number of reactive nitrogen oxide species, such as N2O3 and ONOO-, that can alter critical cellular components under high local concentrations of NO. However, NO can also abate the oxidation chemistry mediated by reactive oxygen species such as H2O2 and O2- that occurs at physiological levels of NO. In addition to the antioxidant chemistry, NO protects against cell death mediated by H2O2, alkylhydroperoxides, and xanthine oxidase. The attenuation of metal/peroxide oxidative chemistry, as well as lipid peroxidation, appears to be the major chemical mechanisms by which NO may limit oxidative injury to mammalian cells. In addition to these chemical and biochemical properties, NO can modulate cellular and physiological processes to limit oxidative injury, limiting processes such as leukocyte adhesion. This review will address these aspects of the chemical biology of this multifaceted free radical and explore the beneficial effect of NO against oxidative stress.

Abstract
We investigated cellular injury and death induced by ultrapure human Hb (HbA(0)) and its diaspirin cross-linked derivative DBBF-Hb in normal and glutathione (GSH)-depleted bovine aortic endothelial cells subjected to hydrogen peroxide (H(2)O(2)). HbA(0) underwent extensive degradation and heme loss, whereas DBBF-Hb persisted longer in its ferryl (Fe(4+)) form. The formation of ferryl HbA(0) or ferryl DBBF-Hb was associated with a significant decrease in endothelial cell GSH compared with the addition of H(2)O(2) or Hbs alone. This effect was inhibited by catalase, but not by superoxide dismutase or deferoxamine mesylate. The presence of HbA(0) and DBBF-Hb reduced H(2)O(2)-induced apoptosis, as measured by cell morphology, annexin V binding assay, and caspase inhibition, consistent with the ability to consume H(2)O(2) in an enzyme-like fashion. However, the pattern of cell death and injury produced by HbA(0) and DBBF-Hb appeared to be distinctly different among proteins as well as among cells with and without GSH. These findings may have important implications for the use of cell-free Hb as oxygen therapeutics in patients with coexisting pathologies who may lack antioxidant protective mechanisms.

Abstract
Metal working fluids (MWFs) are widely used in industry for metal cutting, drilling, shaping, lubricating, and milling. Potential for dermal exposure to MWFs exists for a large number of men and women via aerosols and splashing during the machining operations. It has been reported earlier that occupational exposure to MWFs causes allergic and irritant contact dermatitis. Previously, we showed that dermal exposure of female and male B6C3F1 mice to 5% MWFs for 3 months resulted in accumulation of mast cells and elevation of histamine in the skin. Topical exposure to MWF also resulted in elevated oxidative stress in the liver of both sexes and the testes in males. The goal of this study was to evaluate the interaction between oxidative stress in the skin and topical application of MWF. Oxidative stress in skin ofB6C3F1 mice of both sexes was generated by intradermal injection ofthe hydrogen peroxide (H2O2) -producing enzyme, glucose oxidase with polyethylene glycol (GOD+PEG). In mice given GOD+PEG, topical treatment with MWF (200 microl, 30%, for 1, 3, or 7 days) resulted in a mixed inflammatory cell response, accumulation of peroxidative products, and reduction of GSH content in the skin. Such changes were not observed with MWF treatment alone. These data indicate that oxidative stress can enhance dermal inflammation caused by occupational exposure to MWF.

Abstract
We investigated the toxicity of hemoglobin/myoglobin on endothelial cells under oxidative stress conditions that include cellular hypoxia and reduced antioxidant capacity. Bovine aorta endothelial cells (BAECs), grown on microcarrier beads, were subjected to cycles of hypoxia and reoxygenation in a small volume of medium, and endothelial cell monolayers were depleted of their intracellular glutathione (GSH) by treatment with buthionine sulfoximine. Incubation of diaspirin cross-linked hemoglobin (DBBF-Hb) or horse skeletal myoglobin (Mb) with BAECs subjected to 3 h of hypoxia caused transient oxidation of the hemoproteins to the ferryl form (Fe(4+)). Formation of the ferryl intermediate was decreased in a concentration-dependent manner by the addition of L-arginine, a substrate of NO synthase, after 3 h of hypoxia. Optimal inhibition of ferryl formation, possibly due to the antioxidant action of NO, was achieved with 900 microM L-arginine. Addition of hydrogen peroxide to GSH-depleted cells in the presence of DBBF-Hb or Mb significantly decreased cell viability. Ferryl Mb, but not ferryl DBBF-Hb, was observed in samples analyzed at the end of treatment, which may explain the greater toxicity observed with Mb as opposed to DBBF-Hb. This model may be utilized to identify causative agent(s) associated with hemoprotein cytotoxicity and in designing strategies to suppress or control heme-mediated injury under physiologically relevant conditions.
