Abstract
Over the last 25 years protein S-nitrosylation, also known more correctly as S-nitrosation, has been progressively implicated in virtually every nitric oxide-regulated process within the cardiovascular system. The current, widely-held paradigm is that S-nitrosylation plays an equivalent role as phosphorylation, providing a stable and controllable post-translational modification that directly regulates end-effector target proteins to elicit biological responses. However, this concept largely ignores the intrinsic instability of the nitrosothiol bond, which rapidly reacts with typically abundant thiol-containing molecules to generate more stable disulfide bonds. These protein disulfides, formed via a nitrosothiol intermediate redox state, are rationally anticipated to be the predominant end-effector modification that mediates functional alterations when cells encounter nitrosative stimuli. In this review we present evidence and explain our reasoning for arriving at this conclusion that may be controversial to some researchers in the field.

Abstract
Nitric oxide (NO) is a gaseous signaling molecule impacting many biological pathways. NO is produced in mammals by three nitric oxide synthase (NOS) isoforms: neuronal (nNOS), endothelial (eNOS), and inducible (iNOS). nNOS and eNOS produce low concentrations of NO for paracrine signaling; NO produced and released from one cell diffuses to a neighboring cell where it binds and activates soluble guanylyl cyclase (sGC). iNOS produces high concentrations of NO using NO toxicity to amplify the innate immune response. Recent work has also defined protein cysteine S-nitrosation as a pathway of sGC-independent NO signaling. Though many studies have shown that S-nitrosation regulates the activity of NOS isoforms and other proteins in vivo, many issues need to be resolved to establish S-nitrosation as a viable signaling mechanism. Several chemical mechanisms result in S-nitrosation including transition metal-catalyzed pathways, NO oxidation followed by thiolate reaction, and thiyl radical recombination with NO. Once formed, nitrosothiols can be transferred between cellular cysteine residues via transnitrosation reactions. However, it is largely unclear how these chemical processes result in selective S-nitrosation of specific cellular cysteine residues. S-nitrosation site selectivity may be imparted via direct interactions or colocalization with NOS isoforms that focus chemical or transnitrosation mechanisms of nitrosothiol formation or transfer. Here, we discuss chemical mechanisms of nitrosothiol formation, S-nitrosation of NOS isoforms, and potential S-nitrosation signaling cascades resulting from NOS S-nitrosation.

S-nitrosation of cellular proteins by NO donors in rat embryonic fibroblast 3Y1 cells: factors affecting S-nitrosation. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2011; 2011:450317.

Abstract
The mechanism of protein S-nitrosation in cells is not fully understood. Using rat 3Y1 cells, we addressed this issue. Among S-nitrosothiols and NO donors tested, only S-nitrosocysteine (CysNO) induced S-nitrosation when exposed in Hanks' balanced salt solution (HBSS) and not in serum-containing general culture medium. In HBSS, NO release from CysNO was almost completely abolished by sequestering metal ions with a metal chelator without affecting cellular S-nitrosation. In contrast, L-leucine, a substrate of L-type amino acid transporters (LATs), significantly inhibited S-nitrosation. The absence of S-nitrosation with CysNO in general culture medium resulted not only from a competition with amino acids in the medium for LATs but also from transnitrosation of cysteine residues in serum albumin. Collectively, these results suggest that in simple buffered saline, CysNO-dependent S-nitrosation occurs through a cellular incorporation-dependent mechanism, but if it occurs in general culture media, it may be through an NO-dependent mechanism.

Abstract
It has been established that microdialysis ensured by the passage of aqueous solutions of Fe(3+) complexes with N-methyl-D: -glucamine dithiocarbamate (MGDMGD ) through fine dialysis fibers permeable for compounds with molecular weights below 5 kDa. These fibers can be implanted into heart, liver, and kidney tissues, enabling effective binding of Fe(3+)-MGD complexes to nitric oxide generated in interstitial fluids of narcotized rats in vivo. Subsequent treatment of dialyzate samples (60 μL) with sodium dithionite favors conversion of newly formed diamagnetic NO-Fe(3+)-MGD complexes into electron paramagnetic resonance-detectable NO-Fe(2+)-MGD complexes. The basal levels of NO determined from the concentrations of the complexes in the respective tissues are similar (1 μМ). The microdialysis data suggest that treatment of rats with a water-soluble analogue of nitroglycerine or a dinitrosyl iron complex with thiosulfate induces a long-lasting (>1 h) increase in the steady-state level of NO in animal tissues. This novel technology can be used for comparative analyses of production rates of NO and reactive oxygen species when using iron-dithiocarbamate complexes and spin traps for reactive oxygen species, respectively.

Abstract
The nature of a compound able to induce long-lasting (> or =20 min) relaxation of rat abdominal aorta rings after addition of rapidly (within several minutes) disappeared mono- and binuclear dinitrosyl iron complexes with cysteine (M- and B-DNICs, respectively) (10 micromol) to the Krebs medium has been investigated. It has been found that long-lasting vasorelaxation is not induced either by S-nitrosocysteine formed upon decomposition of DNICs or by accumulation of free nitric oxide molecules or nitrite remaining in the incubation medium. Long-term air bubbling of the Krebs medium initially containing M-DNIC is accompanied by conversion of the complex first into B-DNIC, which represents a Roussin's red salt cysteine ester and then into a more stable diamagnetic compound X, which displays an intense absorption band at 278 nm. Compound X is decomposed after treatment with the strong bivalent iron chelator bathophenanthroline disulfonate (BPDS) and N-methyl-D-glucamine dithiocarbamate (MGD). The MGD-induced decomposition of compound X is concomitant with the formation of EPR-detectable mononitrosyl iron complexes with MGD. Treatment of compound X with cysteine results in its decomposition and the appearance of optical absorption bands characteristic of M- and B-DNICs. Evidently, compound X, has an iron-nitrosyl origin similar to that of M- and B-DNICs and its formation in oxygenated DNIC solutions is determined by the lowering cysteine content in them. It is hypothesized that compound X represents a cysteine ester of nitrosyl iron complexes, namely, a black Roussin's salt cysteine ester responsible for long-lasting vasorelaxation initiated by addition of M- and B-DNICs that are rapidly decomposed to compound X to the incubation medium.

Abstract
Dinitrosyl iron complexes (DNIC) with thiolate ligands and S-nitrosothiols, which are NO and NO+ donors, share the earlier demonstrated ability of nitrite for inhibition of catalase. The efficiency of inhibition sharply (by several orders in concentration of these agents) increases in the presence of chloride, bromide, and thiocyanate. The nitro compounds tested--nitroarginine, nitroglycerol, nitrophenol, and furazolidone--gained the same inhibition ability after incubation with ferrous ions and thiols. This is probably the result of their transformation into DNIC. None of these substances lost the inhibitory effect in the presence of the well known NO scavenger oxyhemoglobin. This fact suggests that NO+ ions rather than neutral NO molecules are responsible for the enzyme inactivation due to nitrosation of its structures. The enhancement of catalase inhibition in the presence of halide ions and thiocyanate might be caused by nitrosyl halide formation. The latter protected nitrosonium ions against hydrolysis, thereby ensuring their transfer to the targets in enzyme molecules. The addition of oxyhemoglobin plus iron chelator o-phenanthroline destroying DNIC sharply attenuated the inhibitory effect of DNIC on catalase. o-Phenanthroline added alone did not influence this effect. Oxyhemoglobin is suggested to scavenge nitrosonium ions released from decomposing DNIC, thereby preventing catalase nitrosation. The mixture of oxyhemoglobin and o-phenanthroline did not affect the inhibitory action of nitrite or S-nitrosothiols on catalase.

Abstract
Previously we established the hypotensive action of nitric oxide donors, dinitrosyl-iron complexes (DNIC) with thiol-containing ligands, stored in frozen solution at 77K. In the present study, we tested recently designed water soluble dry powder preparations of DNICs keeping their characteristics in dry air for a long time. The complexes dissolved in PBS were injected intravenously into normotensive Wistar and spontaneously hypertensive SHR rats. The average arterial pressure (AAP) was recorded through preliminary implanted catheter in a carotid artery. The initial hypotensive action of DNIC with cysteine (DNIC-cys) was comparable to action of nitroprusside (SNP) but, in contrast to the latter, lasted for 20-120min depending on a doze. The blood DNIC content as detected by electronic paramagnetic resonance steadily decreased at this time. The hypotensive action of S-nitrosocysteine was similar to SNP while binding of iron in DNIC by batophenantroline-disulphonate prevented its hypotensive effect. These data suggest that long-lasting hypotensive action of DNICs may be caused by stable protein-bound DNICs forming in the process of transfer of Fe(+)(NO(+))(2) moieties from low-molecular DNICs to thiol protein ligands. The relative initial dose-dependent effect of DNIC-cys was similar in Wistar and SHR but secondary AAP reduction was more profound in SHR. A substitution of cysteine in DNIC by thiosulphate resulted in markedly less initial AAP reduction while long-lasting effect was similar and substitution by glutathione smoothed initial AAP decline and stabilized AAP level in the second phase. Prolonged AAP reduction induced by DNIC-cys was considerably shortened in narcotized rats. Thus, dry preparations of DNICs preserve prolonged hypotensive activity.

Abstract
Vasorelaxant activity of new stable powder preparations of dinitrosyl iron complexes (DNIC) with thiol-containing ligands was investigated on rat abdominal aorta rings. The preparations preserve their physicochemical characteristics (EPR and optical absorption) if stored for a long time in dry air (at least half-year). Three preparations of DNIC were tested: diamagnetic dimeric DNIC with glutathione (DNIC-GS 1:2) or cysteine (DNIC-cys 1:2) and paramagnetic monomeric DNIC with cysteine (DNIC-cys 1:20). Being dissolved in physiological solution the preparations induced relaxation of vessel similarly to that by earlier described non-stable DNICs which should be stored in liquid nitrogen. The amplitudes and kinetic characteristics of the relaxation were dependent on the incorporated thiolate ligands. Rapid transient relaxation followed by significant tone recovery to stationary level (plateau) was observed for DNIC-cys 1:2. DNIC-cys 1:20 also induced initial rapid relaxation followed by incomplete tone recovery. DNIC-GS 1:2 induced slow developing and long lasting relaxation. NO scavenger, hydroxocobalamin (2x10(-5)M) eliminated the rapid transitory relaxation induced by DNIC-cys 1:20 and did not influence significantly on the plateau level. SOD increased duration of the DNIC-cys 1:2 and DNIC-cys 1:20 induced relaxation. The addition of 5x10(-5)M DNIC-cys 1:2 or DNIC-cys 1:20 induced long lasting vasorelaxation within 20min and more. However the EPR measurements demonstrated full rapid disappearance (within 1-2min) of both type of DNIC-cys in Krebs medium bubbled with carbogen gas. This was not the case for DNIC-GS 1:2. We suggested that the long lasting vasorelaxation observed during the addition of DNICs-cys was induced by S-nitrosocysteine derived from DNICs-cys and stabilized by EDTA in Krebs medium. The suggestion is in line with the fact that strong ferrous chelator bathophenantroline disulfonate (BPDS) which is capable of rapid degradation of DNICs did not abrogate the vasorelaxtion induced by DNIC addition.

Abstract
Plasma S-nitrosothiols (RSNOs) may act as a circulating form of nitric oxide that affects vascular function and platelet aggregation. Their role in liver ischemia/reperfusion (I/R) injury is largely unknown. The aim of the present study was to investigate the changes in plasma RSNOs following liver I/R injury. Two groups of New Zealand white rabbits were used (n=6, each): the I/R group underwent 60 min lobar liver ischemia and 7 h reperfusion, while the sham group underwent laparotomy but no liver ischemia. Serial RSNO levels were measured in plasma by electron paramagnetic resonance (EPR) spectrometry, nitrite/nitrates by capillary electrophoresis, hepatic microcirculation by laser Doppler flowmetry, redox state of hepatic cytochrome oxidase by near-infrared spectroscopy, liver iNOS mRNA expression by reverse transcription-polymerase chain reaction (RT-PCR) and the oxidation of dihydrorhodamine to rhodamine by fluorescence. The effect of the antioxidant N-acetylcysteine (NAC) on RSNOs formation and DHR oxidation was tested in a third group of animals (n=6) undergoing lobar liver I/R. Hepatic I/R was associated with a significant increase in plasma RSNOs, plasma nitrites, hepatic iNOS mRNA expression, impairment in hepatic microcirculation, decrease in the redox state of cytochrome oxidase, and significant production of rhodamine. The changes were more obvious during the late phase of reperfusion (>4 h). NAC administration decreased plasma RSNOs and oxidation of DHR to RH (P<0.05, 5 and 7 h postreperfusion, respectively). These results suggest that significant upregulation of nitric oxide synthesis during the late phase of reperfusion is associated with impairment in microcirculation and mitochondrial dysfunction. Plasma S-nitrosothiols are a good marker of this nitric oxide-mediated hepatotoxicity.

Abstract
The in vivo mechanism of NO trapping by iron-dithiocarbamate complexes is considered. Contrary to common belief, we find that in biological systems the NO radicals are predominantly trapped by ferric iron-dithiocarbamates. Therefore, the trapping leads to ferric mononitrosyl complexes which are diamagnetic and cannot be directly detected with Electron Paramagnetic Resonance spectroscopy. The ferric mononitrosyl complexes are far easily reduced to ferrous state with L-cysteine, glutathione, ascorbate or dithiocarbamate ligands than their non-nitrosyl counterpart. When trapping NO in oxygenated biological systems, the majority of trapped nitric oxide is found in diamagnetic ferric mononitrosyl iron complexes. Only a minority fraction of NO is trapped in the form of paramagnetic ferrous mononitrosyl iron complexes with dithiocarbamate ligands. Subsequent ex vivo reduction of biological samples sharply increases the total yield of the paramagnetic mononitrosyl iron complexes. Reduction also eliminates the overlapping EPR spectrum from Cu(2+)-dithiocarbamate complexes. This facilitates the quantification of yields from NO trapping.

Abstract
We present here a brief description of the relationships among metals, nitric oxide metabolism, and ageing. In particular, we will discuss the interactions occurring between redox (copper, iron) and non-redox (zinc) metals and nitric oxide, the metal- and nitric oxide-catalyzed formation of thiol adducts (nitrosothiols, mixed disulphides) and the possible involvement of these species in the ageing process.

Abstract
S-Nitrosocysteine (CysNO) releases either NO (in the presence of divalent cations) or NO+ (in the presence of chelating agents). NO+ is then transferred to peptides or protein SH groups to form high-mass nitrosothiols. The aim of this work was the development of a specific reaction between thiocyanate (SCN-) and CysNO. This reaction selectively liberates NO from CysNO in the presence of high-mass nitrosothiols. Free NO is measured with an amperometric sensor. We examine with this system the transnitrosylation reaction between CysNO and BSA at low molecular ratios and could assay nitrites, SNO-BSA, and CysNO in the incubation mixture without any preliminary purification steps.

Abstract
The conversion of NO into its congeners, nitrosonium (NO+) and nitroxyl (HNO/NO-) species, has important consequences in NO metabolism. Dinitrosyl iron complex (DNIC) combined with thiol ligands was shown to catalyze the conversion of NO into NO+, resulting in the synthesis of S-nitrosothiols (RSNO) both in vitro and in vivo. The formation mechanism of DNIC was proposed to involve the intermediate release of nitroxyl. Since the detection of hydroxylamine (as the product of a rapid reaction of HNO/NO- with thiols) is taken as the evidence for nitroxyl generation, we examined the formation of hydroxylamine, RSNO, and nitrite (the product of a rapid reaction of NO+ with water) in neutral solutions containing iron ions and thiols exposed to NO under anaerobic conditions. Hydroxylamine was detected in NO treated solutions of iron ions in the presence of cysteine, but not glutathione (GSH). The addition of urate, a major "free" iron-binding agent in humans, to solutions of GSH and iron ions, and the subsequent treatment of these solutions with NO increased the synthesis of GSNO and resulted in the formation of hydroxylamine. This caused a loss of urate and yielded a novel nitrosative/nitration product. GSH attenuated the urate decomposition to such a degree that it could be reflected as the function of GSH:urate. Results described here contribute to the understanding of the role of iron ions in catalyzing the conversion of NO into HNO/NO- and point to the role of uric acid not previously described.

Abstract
The mechanisms of S-nitrosothiol transformation into paramagnetic dinitrosyl iron complexes (DNICs) with thiol- or non-thiol ligands or mononitrosyl iron complex (MNICs) with N-methyl-D-glucamine dithiocarbamate catalyzed by iron(II) ions under anaerobic conditions were studied by monitoring EPR or optical features of the complexes and S-nitrosothiols. The kinetic investigations demonstrated the appearance of short-living paramagnetic mononitrosyl-iron complex with L-cysteine prior to the formation of stable dinitrosyl-iron complex with cysteine in the solution of iron(II)-citrate complex (50-100 microM), S-nitrosocysteine (400 microM), and L-cysteine (20 mM) in 100 mM Hepes buffer (pH 7.4). The addition of deoxyhemoglobin (100 microM) did not influence the process, which points to a direct interaction between S-nitrosocysteine and iron(II) ions to yield DNIC. The reaction of DNIC-cysteine formation is first- and second-order in iron and S-nitrosocysteine, respectively. The third-order rate constant is (1.0 +/- 0.2) x 10(5) M(-2) s(-1) (estimated from EPR results) or (2.0 +/- 0.1) x 10(4) M(-2) s(-1) (estimated by optical method). A similar process of DNIC-cysteine formation was observed in a solution of iron(II)-citrate complex, L-cysteine, and NO-proline (200 microM) as a NO* donor. The appearance of a less stable dinitrosyl-iron complex with phosphate was detected when solutions of iron(II)-citrate containing 100 mM phosphate buffer (pH 7.4) were mixed with S-nitrosocysteine or NO-proline. The rapid formation of DNIC with phosphate was followed by its decay. When the concentration of L-cysteine in solutions was reduced from 20 to 1 mM, the life-time of the DNIC-cysteine diminished notably; this was caused by consumption of L-cysteine in the process of DNIC-cysteine formation from S-nitrosocysteine and iron. Thus, L-cysteine is consumed. Formation of DNIC with glutathione was also observed in a solution of glutathione (20 mM), S-nitrosoglutathione (400 microM), and iron(II) complex (800 microM) in 100 mM Hepes buffer (pH 7.4), but the rate of formation was about 10 times slower than the formation of the DNIC-cysteine. The rate of MNIC-MGD formation from iron(II)-MGD complexes and S-nitrosocysteine was first-order in both reactants. The second-order rate constant for this reaction, estimated from EPR measurements, was 30 +/- 5 M(-1) s(-1). Rate constants of MNIC-MGD formation from iron(II)-MGD and the more stable S-nitrosoglutathione and S-nitroso-D,L-penicillamine were equal to 3.0 +/- 0.3 and 0.3 +/- 0.05 M(-1) s(-1), respectively. Thus, the concerted mechanism of DNIC and MNIC formation from S-nitrosothiols and iron(II) ions can be suggested to be predominant.

Abstract
Complex formation between nitrosoglutathione (GSNO) and Zn(II), Cd(II), and Ni(II) ions was studied by potentiometry and spectroscopic techniques. GSNO forms simple ML and ML2 type complexes (L = GSNO) with these ions. The stability of GSNO in HEPES buffer solution, pH 7.4, increased in the presence of both Zn(II) and Cd(II), due to an indirect mechanism. A concentration-dependent destabilization of GSNO by Ni(II) ions was found to be linearly dependent on the NiL complex concentration. NiL forms ternary complexes readily. The NiLA- stoichiometry was found for l-His, and NiHLB3- and NiLB4- complexes were detected for GSSG as the second ligand. The formation of these complexes was found to inhibit GSNO decay, by limiting the concentration of the NiL complex. The mechanism of Ni(II)-assisted GSNO decomposition contains several steps, with a hypothetical ternary complex with GSH as a likely active form. These results provide experimental evidence for the stabilization of GSNO in solution by metal ions, which may provide an additional level of control and/or impairment of cellular redox signaling. The Ni(II)-dependent destabilization of GSNO may constitute a novel epigenetic mechanism in nickel carcinogenesis.

Abstract
The ability of various nitric oxide (NO) donors to induce long-lasting inhibition of contraction in isolated arteries was compared. All the studied compounds elicited a relaxant effect in rat aortic rings precontracted with norepinephrine (NE). Almost maximal relaxation was obtained with 1 microM of each compound. The S-nitrosating agents S-nitrosoglutathione (GSNO), S-nitroso-N-acetylpenicillamine, S-nitroso-N-acetylcysteine, and sodium nitroprusside (1 microM) produced a decrease of the maximal effect of NE that persisted after removal of the drug. This hyporesponsiveness to NE was associated with a relaxant effect of N-acetylcysteine, a low-molecular weight thiol that can displace NO from cysteine-NO bonds. Such modifications of contraction were not observed in aortic rings previously exposed to 1 microM S-nitrosocysteine, glyceryl trinitrate, 3-morpholinosydnonimine, or 2-(N,N-diethylamino)-diazenolate-2-oxide (DEA-NO). The same differential effects of GSNO and DEA-NO on contraction were also observed in porcine coronary arteries. Rat aortic rings previously exposed to 100 microM GSNO, but not to 100 microM DEA-NO, displayed a persistent increase in NO content (determined by NO spin trapping) and cysteine-NO residues (determined by immunostaining with an anti-cysteine-NO antiserum). The GSNO-induced increase in cysteine-NO residues in aortic tissue was prevented by the thiolmodifying agent p-hydroxymercuribenzoic acid. This study shows that in isolated arteries, the effects of S-nitrosating agents differed from those of other NO-donating agents. S- Nitrosating agents induced a persistent inhibition of contraction, which was attributed to the formation of releasable NO stores by S-nitrosation of tissue thiols. These differential effects of NO donors may be important for orientating their therapeutic indications.

Abstract
We studied the capability of dimeric forms of dinitrosyl-iron complexes and S-nitrosothiols to activate soluble guanylate cyclase (sGC) from human platelet cytosol. The dinitrosyl-iron complexes had the ligands glutathione (DNIC-GS) or N-acetylcysteine (DNIC-NAC). The S-nitrosothiols were S-nitrosoglutathione (GS-NO) or S-nitrosoacetylcysteine (SNAC). For both glutathione and N-acetylcysteine, the DNIC and S-nitrosothiol forms are equally effective activators of sGC. The activation mechanism is strongly affected by the presence of intrinsic metal ions. Pretreatment with the potent iron chelator, disodium salt of bathophenanthroline disulfonic acid (BPDS), suppressed sGC activation by GS-NO: the concentration of GS-NO producing maximal sGC activation was increased by two orders of magnitude. In contrast, activation by DNIC-GS is strongly enhanced by BPDS. When BPDS was added 10 min after supplementation of DNIC-GS or GS-NO at 4 degrees C, it exerted a similar effect on sGC activation by either NO donor: BPDS only enhanced the sGC stimulation at low concentrations of the NO donors. Our experiments demonstrated that both Fe(2+) and Cu(2+) ions contribute to the decomposition of GS-NO in the presence of ascorbate. The decomposition of GS-NO induced by Fe(2+) ions was accompanied by formation of DNIC. BPDS protected GS-NO against the destructive action of Fe(2+) but not Cu(2+) ions. Additionally, BPDS is a sufficiently strong chelator to remove the iron from DNIC-GS complexes. Based on our data, we propose that S-nitrosothiols activate sGC via a two-step iron-mediated process: In the first step, intrinsic Fe(2+) ions catalyze the formation of DNICs from S-nitrosothiols. In the secondary step, these newly formed DNICs act as the real NO donors responsible for sGC activation.
