Abstract
In order to explore the unique physiological roles of gas signaling molecules and gasotransmitters in vivo, chemists have engineered a variety of gas-responsive polymers that can monitor their changes in cellular milieu, and gas-releasing polymers that can orchestrate the release of gases. These have advanced their potential applications in the field of bio-imaging, nanodelivery, and theranostics. Since these polymers are of different chain structures and properties, the morphology of their assemblies will manifest distinct transitions after responding to gas or releasing gas. In this review, we summarize the fundamental design rationale of gas-responsive and gas-releasing polymers in structure and their controlled transition in self-assembled morphology and function, as well as present some perspectives in this prosperous field. Emerging challenges faced for the future research are also discussed.

Abstract
C-Nitrosothioformamide was demonstrated to be a donor template for dual release of HNO and COS triggered by a retro-Diels-Alder reaction. COS is an H2S precursor in the presence of carbonic anhydrase. This process produces HNO and H2S in a slow but steady manner. As such, the direct reaction between HNO and H2S under this situation appears to be minor. This may provide a useful tool to study the synergistic effects of HNO and H2S.

Abstract
Sepsis, a potentially lethal condition resulting from failure to control the initial infection, is associated with a dysregulated host defense response to pathogens and their toxins. Sepsis remains a leading cause of morbidity, mortality and disability worldwide. The pathophysiology of sepsis is very complicated and is not yet fully understood. Worse still, the development of effective therapeutic agents is still an unmet need and a great challenge. Gases, including nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S), are small-molecule biological mediators that are endogenously produced, mainly by enzyme-catalyzed reactions. Accumulating evidence suggests that these gaseous mediators are widely involved in the pathophysiology of sepsis. Many sepsis-associated alterations, such as the elimination of invasive pathogens, the resolution of disorganized inflammation and the preservation of the function of multiple organs and systems, are shaped by them. Increasing attention has been paid to developing therapeutic approaches targeting these molecules for sepsis/septic shock, taking advantage of the multiple actions played by NO, CO and H2S. Several preliminary studies have identified promising therapeutic strategies for gaseous-mediator-based treatments for sepsis. In this review article, we summarize the state-of-the-art knowledge on the pathophysiology of sepsis; the metabolism and physiological function of NO, CO and H2S; the crosstalk among these gaseous mediators; and their crucial effects on the development and progression of sepsis. In addition, we also briefly discuss the prospect of developing therapeutic interventions targeting these gaseous mediators for sepsis.

Abstract
In addition to being notorious air pollutants, nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S) have also been known as endogenous gaseous signaling molecules (GSMs). These GSMs play critical roles in maintaining the homeostasis of living organisms. Importantly, the occurrence and development of many diseases such as inflammation and cancer are highly associated with the concentration changes of GSMs. As such, GSMs could also be used as new therapeutic agents, showing great potential in the treatment of many formidable diseases. Although clinically it is possible to directly inhale GSMs, the precise control of the dose and concentration for local delivery of GSMs remains a substantial challenge. The development of gaseous signaling molecule-releasing molecules provides a great tool for the safe and convenient delivery of GSMs. In this review article, we primarily focus on the recent development of macromolecular nanocarriers for the local delivery of various GSMs. Learning from the chemistry of small molecule-based donors, the integration of these gaseous signaling molecule-releasing molecules into polymeric matrices through physical encapsulation, post-modification, or direct polymerization approach renders it possible to fabricate numerous macromolecular nanocarriers with optimized pharmacokinetics and pharmacodynamics, revealing improved therapeutic performance than the small molecule analogs. The development of GSMs represents a new means for many disease treatments with unique therapeutic outcomes.

Abstract
The local delivery of gaseous signaling molecules (GSMs) has shown promising therapeutic potential. However, although GSMs have a subtle interplay in physiological and pathological conditions, the co-delivery of different GSMs for therapeutic purposes remains unexplored. Herein, we covalently graft a nitric oxide (NO)-releasing N-nitrosamine moiety onto the carbon monoxide (CO)-releasing 3-hydroxyflavone (3-HF) antenna, resulting in the first NO/CO-releasing donor. Under visible light irradiation, photo-mediated co-release of NO and CO reveals a superior antimicrobial effect toward Gram-positive bacteria with a combination index of 0.053. The synergy of NO and CO hyperpolarizes and permeabilizes bacterial membranes, which, however, shows negligible hemolysis and no evident toxicity toward normal mammalian cells. Moreover, the co-release of NO and CO can efficiently treat MRSA infection in a murine skin wound model, showing a better therapeutic capacity than vancomycin.

Abstract
Hydrogen sulfide (H2S) plays a vital role in human physiology and in the pathophysiology of several diseases. In addition, a substantial role of H2S in inflammation has emerged. This chapter will discuss the involvement of H2S in various inflammatory diseases. Furthermore, the contribution of reactive oxygen species (ROS), adhesion molecules, and leukocyte recruitment in H2S-mediated inflammation will be discussed. The interrelationship of H2S with other gasotransmitters in inflammation will also be examined. There is mixed literature on the contribution of H2S to inflammation due to studies reporting both pro- and anti-inflammatory actions. These apparent discrepancies in the literature could be resolved with further studies.

Abstract
Acute kidney injury (AKI) is a syndrome affecting most patients hospitalized due to kidney disease; it accounts for 15 % of patients hospitalized in intensive care units worldwide. AKI is mainly caused by ischemia and reperfusion (IR) injury, which temporarily obstructs the blood flow, increases inflammation processes and induces oxidative stress. AKI treatments available nowadays present notable disadvantages, mostly for patients with other comorbidities. Thus, it is important to investigate different approaches to help minimizing side effects such as the ones observed in patients subjected to the aforementioned treatments. Therefore, the aim of the current review is to highlight the potential of two endogenous gasotransmitters - hydrogen sulfide (H2S) and nitric oxide (NO) - and their crosstalk in AKI treatment. Both H2S and NO are endogenous signalling molecules involved in several physiological and pathophysiological processes, such as the ones taking place in the renal system. Overall, these molecules act by decreasing inflammation, controlling reactive oxygen species (ROS) concentrations, activating/inactivating pro-inflammatory cytokines, as well as promoting vasodilation and decreasing apoptosis, hypertrophy and autophagy. Since these gasotransmitters are found in gaseous state at environmental conditions, they can be directly applied by inhalation, or in combination with H2S and NO donors, which are compounds capable of releasing these molecules at biological conditions, thus enabling higher stability and slow release of NO and H2S. Moreover, the combination between these donor compounds and nanomaterials has the potential to enable targeted treatments, reduce side effects and increase the potential of H2S and NO. Finally, it is essential highlighting challenges to, and perspectives in, pharmacological applications of H2S and NO to treat AKI, mainly in combination with nanoparticulated delivery platforms.

Abstract
Vacuolar H+ -ATPase (V-ATPase; EC 3.6.3.14) is the main enzyme responsible for generating a proton gradient across the tonoplast. Under cadmium (Cd) stress conditions, V-ATPase activity is inhibited. In the present work, hydrogen sulfide (H2 S) and hydrogen peroxide (H2 O2 ) cross-talk was analyzed in cucumber (Cucumis sativus L.) seedlings exposed to Cd to explain the role of both signaling molecules in the control of V-ATPase. V-ATPase activity and gene expression as well as H2 S and H2 O2 content and endogenous production were determined in roots of plants treated with 100 μM CdCl2 and different inhibitors or scavengers. It was found that H2 S donor improved photosynthetic parameters in Cd-stressed cucumber seedlings. Cd-induced stimulation of H2 S level was correlated with the increased activities of the H2 S-generating desulfhydrases. Increased H2 O2 and lowered H2 S contents in roots were able to reduce V-ATPase activities similar to Cd. H2 O2 and H2 S-induced modulations in V-ATPase activities were not closely related to the transcript level of encoding genes, suggesting posttranslational modifications of enzyme protein. On the other hand, exogenous H2 O2 raised H2 S content in root tissues independently from the desulfhydrase activity. Although treatment of control plants with H2 S significantly stimulated NADPH oxidase activity and gene expression, H2 S did not affect H2 O2 accumulation in roots exposed to Cd. The results suggest the existence of two pathways of H2 S generation in Cd-stressed cucumber roots. One involves desulfhydrase activity, as was previously demonstrated in different plant species. The other, the desulfhydrase-independent pathway induced by H2 O2 /NADPH oxidase, may protect V-ATPase from inhibition by Cd.

Hydrogen sulfide (H2S) and nitric oxide (NO) are now recognized as important regulators in the cardiovascular system, although they were historically considered as toxic gases. As gaseous transmitters, H2S and NO share a wide range of physical properties and physiological functions: they penetrate into the membrane freely; they are endogenously produced by special enzymes, they stimulate endothelial cell angiogenesis, they regulate vascular tone, they protect against heart injury, and they regulate target protein activity via posttranslational modification. Growing evidence has determined that these two gases are not independent regulators but have substantial overlapping pathophysiological functions and signaling transduction pathways. H2S and NO not only affect each other's biosynthesis but also produce novel species through chemical interaction. They play a regulatory role in the cardiovascular system involving similar signaling mechanisms or molecular targets. However, the natural precise mechanism of the interactions between H2S and NO remains unclear. In this review, we discuss the current understanding of individual and interactive regulatory functions of H2S and NO in biosynthesis, angiogenesis, vascular one, cardioprotection, and posttranslational modification, indicating the importance of their cross-talk in the cardiovascular system.

Involvement of signalling molecules NO, H 2O 2 and H 2S in modification of plasma membrane proton pump in cucumber roots subjected to salt or low temperature stress. FUNCTIONAL PLANT BIOLOGY : FPB 2018; 45:428-439.

Abstract
In the present study we demonstrate that the signalling molecules NO, H2O2 and H2S are important for understanding the mechanisms of modification of plasma membrane H+-ATPase (EC 3.6.3.14) activity in conditions of both salt (50mM NaCl) and low temperature (10°C, LT) stress. Plants were subjected to stress conditions for 1 or 6 days. After 3 days of exposure to stress some of the plants were transferred to control conditions for another 3 days: post-stressed plants (3+3). We measured the endogenous levels of signalling molecules in stressed plants. To determine the physiological significance of NO, H2O2 and H2S induced activity of plasma membrane H+-ATPase (PM H+-ATPase) in salt and LT stresses, we investigated the activity of the plasma membrane proton pump in stress conditions, and plants were additionally supplemented with PTIO (a scavenger of NO), ascorbic acid (a scavenger of H2O2) or hypotaurine (a scavenger of H2S). H2S contributed to increased activity of PM H+-ATPase in short-term salt stress (1 day) and in low temperature treated plants (both 6 days and post-stressed plants), by stimulation of expression of several genes encoding isoforms of the plasma membrane proton pump (CsHA2, CsH4, CsH8, CsH9 and CsHA10). In contrast, NO and H2O2 play a minor role in the regulation of ATPase activity at the genetic level, because they significantly increased the expression of only one isoform, CsHA1, the expression level of which was very low in the tissues of the control plants, and additionally they slightly increased the expression of the gene encoding the isoform CsHA2. However, NO plays an important role in stimulation of the plasma membrane proton pumps under salt stress and low temperature. NO participates in post-translational modifications because it leads to increased enzyme phosphorylation and an increased H+/ATP coupling ratio.

Nitric Oxide and Hydrogen Sulfide Interact When Modulating Gastric Physiological Functions in Rodents. Dig Dis Sci 2017; 62:93-104.

Abstract
AIM The objective was to evaluate the effects of nitric oxide (NO) and hydrogen sulfide (H2S) donors and possible interactions between these two systems in modulating gastric function. METHODS Mice received saline, sodium nitroprusside (SNP), or sodium hydrosulfite (NaHS), and after 1 h, the animals were killed for immunofluorescence analysis of CSE or eNOS expressions, respectively. Other groups received saline, SNP, NaHS, Lawesson's reagent (H2S donor), PAG + SNP, L-NAME, L-NAME + NaHS, or L-NAME + Lawesson's reagent. Then, the gastric secretions (mucous and acid), gastric blood flow, gastric defense against ethanol, and gastric motility (gastric emptying and gastric contractility) were evaluated. RESULTS SNP and NaHS increased the expression of CSE or eNOS, respectively. SNP or Lawesson's reagent did not alter gastric acid secretion but increased mucus production, and these effects reverted with PAG and L-NAME treatment, respectively. SNP or NaHS increased gastric blood flow and protected the gastric mucosa against ethanol injury, and these effects reverted with PAG and L-NAME treatments, respectively. SNP delayed gastric emptying when compared with saline, and PAG partially reversed this effect. NaHS accelerate gastric emptying, and L-NAME partially reversed this effect. SNP and NaHS alone induced gastric fundus and pylorus relaxation. However, pretreatment with PAG or L-NAME reversed these relaxant effects only in the pylorus but not in the gastric fundus. CONCLUSION NO and H2S interact in gastric physiological functions, and this "cross-talk" is important in the control of mucus secretion, gastric blood flow, gastric mucosal defense, and gastric motility, but not in the control of basal gastric acid secretion.

Abstract
In the past years, biomedical research has recognized hydrogen sulfide (H₂S) not only as an environmental pollutant but also, along with nitric oxide and carbon monoxide, as an important biological gastransmitter with paramount roles in health and disease. Current research focuses on several aspects of H₂S biology such as the biochemical pathways that generate the compound and its functions in human pathology or drug synthesis that block or stimulate its biosynthesis. The present work addresses the knowledge we have to date on H₂S production and its biological roles in the general human environment with a special focus on the oral cavity and its involvement in the initiation and development of periodontal diseases.

Abstract
Aim To evaluate the effect of ginkgolide B treatment on vascular endothelial function in diabetic rats. Methods The study included four groups with 15 male Sprague-Dawley rats: control group; control group treated with ginkgolide B; diabetic group; and diabetic treated with ginkgolide B. The activity of superoxide dismutase (SOD), malondialdehyde content, and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase subunits, and glutathione peroxidase 1 (GPX1) protein expression were determined in aortic tissues. Vasoconstriction to phenylephrine (PHE) and vasorelaxation to acetylcholine (Ach) and sodium nitroprusside (SNP) were assessed in aortic rings. Nitric oxide (NO) and hydrogen sulfide (H2S) were measured, as well as cystathionine γ lyase (CSE) and cystathionine β synthetase (CBS) protein expression, and endothelial nitric oxide synthase (eNOS) activity. Results Diabetes significantly impaired PHE-induced vasoconstriction and Ach-induced vasorelaxation (P < 0.001), reduced NO bioavailability and H2S production (P < 0.001), SOD activity, and GPX1 protein expression (P < 0.001), and increased malondialdehyde content and NADPH oxidase subunits, and CSE and CBS protein expression (P < 0.001). Ginkgolide B treatment improved PHE vasoconstriction and Ach vasorelaxation (P < 0.001), restored SOD (P = 0.005) and eNOS (P < 0.001) activities, H2S production (P = 0.044) and decreased malondialdehyde content (P = 0.014). Vasorelaxation to SNP was not significantly different in control and diabetic rats with or without ginkgolide B treatment. Besides, ginkgolide B increased GPX1 protein expression and reduced NADPH oxidase subunits, CBS and CSE protein expression. Conclusion Ginkgolide B alleviates endothelial dysfunction by reducing oxidative stress and elevating NO bioavailability and H2S production in diabetic rats.

Abstract
Uveitis is a sight-threatening inflammatory disease of the eye which represents the third leading cause of blindness in the developed countries. The conventional pharmacological treatment includes corticosteroids and immunosuppressive agents, which are limited by their side effects. New therapeutic strategies are thus strongly needed. Exogenously-administered carbon monoxide (CO) may represent an effective treatment for conditions characterized by a dysregulated inflammatory response. Carbon monoxide-releasing molecules (CORMs) are a novel group of compounds capable of carrying and liberating controlled quantities of CO. Among CORMs, CORM-A1 represents the first example of water soluble CO releaser. We show here that CORM-A1 under a late prophylactic regime is able to significantly ameliorate the natural course of experimental autoimmune uveoretinitis, a rodent model of immunoinflammatory posterior uveitis. The present study strongly supports the development of CORM-A1 as a potential new drug for treatment of patients with non-infectious posterior uveitis.

Abstract
Together with carbon monoxide (CO), nitric oxide (NO) and hydrogen sulfide (H2S) form a group of physiologically important gaseous transmitters, sometimes referred to as the "gaseous triumvirate". The three molecules share a wide range of physical and physiological properties: they are small gaseous molecules, able to freely penetrate cellular membranes; they are all produced endogenously in the body and they seem to exert similar biological functions. In the cardiovascular system, for example, they are all vasodilators, promote angiogenesis and protect tissues against damage (e.g. ischemia-reperfusion injury). In addition, they have complex roles in inflammation, with both pro- and anti-inflammatory effects reported. Researchers have focused their efforts in understanding and describing the roles of each of these molecules in different physiological systems, and in the past years attention has also been given to the gases interaction or "cross-talk". This review will focus on the role of NO and H2S in inflammation and will give an overview of the evidence collected so far suggesting the importance of their cross-talk in inflammatory processes.

Abstract
Mesenchymal stem cells (MSCs) have great potential for repair following acute myocardial infarction. However, a major challenge to MSC therapy is that transplanted cells undergo apoptosis. Hydrogen sulfide (H2S) has recently been proposed as an endogenous mediator of cell apoptosis in various systems. The aim of the present study was to investigate the role of endogenous H2S in hypoxia and serum deprivation (hypoxia/SD)-induced apoptosis in MSCs. The present study demonstrated that exposure of MSCs to hypoxia/SD caused a significant decrease in H2S generation and resulted in marked cell apoptosis. Furthermore, under basal conditions, MSCs expressed cystathionine γ-lyase (CSE) and synthesized H2S, whereas CSE expression and activity was inhibited by hypoxia/SD treatment. Overexpression of CSE not only markedly prevented hypoxia/SD-induced decreases in endogenous H2S generation but also protected MSCs from apoptosis, while inhibition of CSE by its potent inhibitors significantly deteriorated the effect of hypoxia/SD in MSCs. These data indicate that the H2S generation pathway exists in MSCs and the inhibition of the endogenous CSE/H2S system contributes to hypoxia/SD-induced apoptosis in MSCs. Our findings suggest that modulation of the CSE/H2S system is a potential therapeutic avenue for promoting the viability of transplanted MSCs.

Abstract
Hypoxia affects inflammation by modulating T-cell activation via the adenosinergic system. We supposed that, in turn, inflammation influences cell hypoxic behavior and that stimulation of T-cells in inflammatory conditions involves the concerted action of the nuclear factor κB (NF-κB) and the related hypoxia-inducible factor 1α (HIF-1α) on the adenosinergic system. We addressed this hypothesis by monitoring both transcription factors and four adenosinergic signaling parameters - namely adenosine, adenosine deaminase (ADA), adenosine A2A receptor (A2AR) and cAMP - in T-cells stimulated using phorbol myristate acetate and phytohemagglutinin and submitted to hypoxic conditions which were mimicked using CoCl2 treatment. We found that cell viability was more altered in stimulated than in resting cells under hypoxia. Detailed analysis showed that: i) NF-κB activation remained at basal level in resting hypoxic cells but greatly increased following stimulation, stimulated hypoxic cells exhibiting the higher level; ii) HIF-1α production induced by hypoxia was boosted via NF-κB activation in stimulated cells whereas hypoxia increased HIF-1α production in resting cells without further activating NF-κB; iii) A2AR expression and cAMP production increased in stimulated hypoxic cells whereas adenosine level remained unchanged due to ADA regulation; and iv) the presence of H2S, an endogenous signaling molecule in inflammation, reversed the effect of stimulation on cell viability by down-regulating the activity of transcription factors and adenosinergic immunosuppression. We also found that: i) the specific A2AR agonist CGS-21680 increased the suppressive effect of hypoxia on stimulated T-cells, the antagonist ZM-241385 exhibiting the opposite effect; and ii) Rolipram, a selective inhibitor of cAMP-specific phosphodiesterase 4, and 8-Br-cAMP, a cAMP analog which preferentially activates cAMP-dependent protein kinase A (PKA), increased T-cell immunosuppression whereas H-89, a potent and selective inhibitor of cAMP-dependent PKA, restored cell viability. Together, these data indicate that inflammation enhances T-cell sensitivity to hypoxia via NF-κB activation. This process upregulates A2AR expression and enhances cAMP production and PKA activation, resulting in adenosinergic T-cell immunosuppression that can be modulated via H2S.

Abstract
Resveratrol (Res) and its two natural analogs that are also related to Res metabolism, piceatannol (Pic) and 3,5,4'-trans-trimethoxystilbene (TMS), were compared in their ability to suppress lipopolysaccharide (LPS)-induced production of proinflammatory tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) and to induce anti-inflammatory heme oxygenase-1 (HO-1) expression in RAW264.7 macrophages. At non-cytotoxic concentrations, they differentially suppressed LPS-induced production of TNF-α and IL-1β; the relative potency for suppression of TNF-α and IL-1β production was Pic > Res > TMS. Res and Pic differentially induced HO-1 expression; Pic, which possesses four hydroxyl groups, was more active in inducing HO-1 expression than Res that contains three hydroxyl groups. TMS, which has none of hydroxyl groups, failed to induce HO-1 expression. These findings suggest that the hydroxyl groups of Res analogs are important for suppression of TNF-α and IL-1β production and HO-1 expression. Interestingly, protoporphyrin-IX, a competitive inhibitor of HO-1 activity, partly attenuated the inhibitory effects of Res and Pic (but not TMS) on TNF-α and IL-1β production, suggesting that suppression of TNF-α and IL-1β production correlates at least in part with HO-1 expression. Overall, the ability of Res analogs to induce HO-1 expression may provide one of possible mechanisms of their anti-inflammatory action.

Abstract
Hydrogen sulfide (H2S) is a naturally occurring gaseous transmitter, which is important in normal physiology and disease. In the present study, the involvement of H2S in the regulation of the immune response induced by burn injury was investigated in mice. Adult male C57BL/6 mice were subjected to burn injuries and treated with vehicle (0.9% sodium chloride, NaCl; 100 ml/kg body weight; subcutaneously, s.c.) or the H2S donor (sodium hydrosulfide, NaHS; 2 mg/kg body weight; s.c.). Compared with the controls, mice which received burn injuries exhibited a significant decrease in plasma H2S levels. Moreover, the levels of tumor necrosis factor (TNF)‑α, interleukin (IL)‑6 and IL‑8 significantly increased, while IL‑10 levels were decreased, compared with that of the controls in the plasma of mice subjected to burn injuries. Myeloperoxidase (MPO) activity in the liver tissue of injured mice was also markedly higher compared with that of the control group. However, the administration of NaHS significantly decreased the levels of TNF‑α, IL‑6 and IL‑8 but increased the levels of IL‑10 in the plasma of mice subjected to burn injuries. In addition, the MPO activity was decreased by NaHS. These results suggested that H2S regulates the inflammatory response induced by burn injury by modulating the levels of TNF‑α, IL‑6, IL‑8 and IL‑10. Thus, it was proposed that the administration of the H2S donor, NaHS, may be a useful therapy against the exaggerated immune response that is associated with burn injury.

Abstract
AMP-activated protein kinase (AMPK), a crucial regulator of energy metabolic homeostasis, is suggested to regulate inflammatory responses, but its precise mechanisms are not fully understood. It has been reported that pharmacological activation of AMPK induces heme oxygenase-1 (HO-1) expression. β-Lapachone (BL), a well-known substrate of NAD(P)H:quinone oxidoreductase (NQO1), has been demonstrated to stimulate AMPK activation via NQO1 activation, and to exert anti-inflammatory effects in macrophages. Here we examined whether AMPK activation by BL would be linked to HO-1 expression in RAW264.7 macrophages and whether HO-1 expression could mediate the anti-inflammatory effects of BL. BL treatment induced concentration- and time-dependent AMPK phosphorylation and HO-1 expression. 5-Aminoimidazole-4-carboxamide-1-β-D-ribofuranoside, an AMPK activator, also induced HO-1 expression. In contrast, compound C (CC), an inhibitor of AMPK activation, prevented the increase in BL-induced HO-1 expression. BL pretreatment reduced lipopolysaccharide-induced production of tumor necrosis factor-α, a pro-inflammatory cytokine, and expression of inducible nitric oxide synthase, a pro-inflammatory enzyme. These inhibitory effects BL were almost completely abolished by CC and partly by tin protoporphyrin-IX, a competitive inhibitor of HO-1. Accordingly, the present results indicate that BL induces anti-inflammatory HO-1 expression in macrophages via AMPK activation, providing one of possible mechanisms by which BL can exert anti-inflammatory effects.

Abstract
Hydrogen sulfide is rapidly gaining ground as a physiological mediator of inflammation, but there is no clear consensus as to its precise role in inflammatory signaling. This article discusses the disparate anti-inflammatory ('the good') and proinflammatory ('the bad') effects of endogenous and pharmacological H(2)S in disparate animal model and cell culture systems. We also discuss 'the ugly', such as problems of using wholly specific inhibitors of enzymatic H(2)S synthesis, and the use of pharmacological donor compounds, which release H(2)S too quickly to be physiologically representative of endogenous H(2)S synthesis. Furthermore, recently developed slow-release H(2)S donors, which offer a more physiological approach to understanding the complex role of H(2)S in acute and chronic inflammation ('the promising') are discussed.

Abstract
Hydrogen sulfide (H(2)S) is known to play a physiological role in processes as diverse as vasodilation, maintenance of vascular tone, neurotransmission, and immune response. The multitude of physiological functions in which H(2)S is involved warrants the development of useful methods for its detection. Here, we introduce a simple and continuous H(2)S detection method that exploits the relatively high polydimethylsiloxane (PDMS) permeability of H(2)S in comparison to other thiols typically encountered in the cellular milieu. In this method, 96-well inserts constructed of PDMS act as an H(2)S-permeable membrane, eliminating nonspecific thiol detection. This design also makes it possible to use virtually any available thiol-specific probe such as Ellman's reagent which was used here to detect H(2)S once it crossed the PDMS membrane. Utilizing this method, a detection limit of 9.2 ± 1.9 ppb(m) (parts per billion (by mole) or ~0.51 μM in 1.6 mL of buffer) free H(2)S (detected as solution sulfide) was achieved. In addition, the assay was used to determine K(M) and V(max) for natural substrates of cystathionine γ-lyase (CSE), the main enzyme responsible for H(2)S production in peripheral tissues. The K(M) and V(max) of CSE for cysteine were 3.79 ± 2.07 mM and 0.37 ± 0.02 nmol H(2)S/min, respectively. K(M) and V(max) for homocysteine were 6.90 ± 1.78 mM and 1.10 ± 0.19 nmol H(2)S/min, respectively. In addition, the assay was used to examine the potential for a direct interaction of H(2)S and NO. The levels of detected H(2)S decreased in the presence of NO under normoxia but not under anoxia indicating that H(2)S does not react with NO but with N(2)O(3) likely formed in the hydrophobic environment of PDMS.

Abstract
CO is a colorless and odorless gas produced by the incomplete combustion of hydrocarbons, both of natural and anthropogenic origin. Several microorganisms, including aerobic and anaerobic bacteria and anaerobic archaea, use exogenous CO as a source of carbon and energy for growth. On the other hand, eukaryotic organisms use endogenous CO, produced during heme degradation, as a neurotransmitter and as a signal molecule. CO sensors act as signal transducers by coupling a "regulatory" heme-binding domain to a "functional" signal transmitter. Although high CO concentrations inhibit generally heme-protein actions, low CO levels can influence several signaling pathways, including those regulated by soluble guanylate cyclase and/or mitogen-activated protein kinases. This review summarizes recent insights into CO metabolism, sensing, and signaling.

Abstract
Excess production of nitric oxide by activated macrophages via inducible nitric oxide synthase leads to the development of various inflammatory diseases. Heme oxygenase-1 expression via activation of nuclear factor-erythroid 2-related factor 2 inhibits nitric oxide production and inducible nitric oxide synthase expression in activated macrophages. Okanin is one of the most abundant chalcones found in the genus Bidens (Asteraceae) that is used as various folk medications in Korea and China for treating inflammation. Here, we found that okanin (possessing the α-β unsaturated carbonyl group) induced heme oxygenase-1 expression via nuclear factor-erythroid 2-related factor 2 activation in RAW264.7 macrophages. 3-Penten-2-one, of which structure, as in okanin, possesses the α-β unsaturated carbonyl group, also induced nuclear factor-erythroid 2-related factor 2-dependent heme oxygenase-1 expression, while both 2-pentanone (lacking a double bond) and 2-pentene (lacking a carbonyl group) were virtually inactive. In lipopolysaccharide-activated RAW264.7 macrophages, both okanin and 3-penten-2-one inhibited nitric oxide production and inducible nitric oxide synthase expression via heme oxygenase-1 expression. Collectively, our findings suggest that by virtue of its α-β unsaturated carbonyl functional group, okanin can inhibit nitric oxide production and inducible nitric oxide synthase expression via nuclear factor-erythroid 2-related factor 2-dependent heme oxygenase-1 expression in lipopolysaccharide-activated macrophages.

Abstract
Hydrogen sulfide (H2S) has been shown to protect against oxidative stress injury and inflammation in various hypoxia-induced insult models. However, it remains unknown whether H2S protects human skin keratinocytes (HaCaT cells) against chemical hypoxia-induced damage. In the current study, HaCaT cells were treated with cobalt chloride (CoCl2), a well known hypoxia mimetic agent, to establish a chemical hypoxia-induced cell injury model. Our findings showed that pretreatment of HaCaT cells with NaHS (a donor of H2S) for 30 min before exposure to CoCl2 for 24 h significantly attenuated CoCl2-induced injuries and inflammatory responses, evidenced by increases in cell viability and GSH level and decreases in ROS generation and secretions of IL-1β, IL-6 and IL-8. In addition, pretreatment with NaHS markedly reduced CoCl2-induced COX-2 overexpression and PGE2 secretion as well as intranuclear NF-κB p65 subunit accumulation (the central step of NF-κB activation). Similar to the protective effect of H2S, both NS-398 (a selective COX-2 inhibitor) and PDTC (a selective NF-κB inhibitor) depressed not only CoCl2-induced cytotoxicity, but also the secretions of IL-1β, IL-6 and IL-8. Importantly, PDTC obviously attenuated overexpression of COX-2 induced by CoCl2. Notably, NAC, a ROS scavenger, conferred a similar protective effect of H2S against CoCl2-induced insults and inflammatory responses. Taken together, the findings of the present study have demonstrated for the first time that H2S protects HaCaT cells against CoCl2-induced injuries and inflammatory responses through inhibition of ROS-activated NF-κB/COX-2 pathway.

Abstract
Hydrogen sulfide (H(2)S) has become the hot new signaling molecule that seemingly affects all organ systems and biological processes in which it has been investigated. It has also been shown to have both proinflammatory and anti-inflammatory actions and proapoptotic and anti-apoptotic effects and has even been reported to induce a hypometabolic state (suspended animation) in a few vertebrates. The exuberance over potential clinical applications of natural and synthetic H(2)S-"donating" compounds is understandable and a number of these function-targeted drugs have been developed and show clinical promise. However, the concentration of H(2)S in tissues and blood, as well as the intrinsic factors that affect these levels, has not been resolved, and it is imperative to address these points to distinguish between the physiological, pharmacological, and toxicological effects of this molecule. This review will provide an overview of H(2)S metabolism, a summary of many of its reported "physiological" actions, and it will discuss the recent development of a number of H(2)S-donating drugs that show clinical potential. It will also examine some of the misconceptions of H(2)S chemistry that have appeared in the literature and attempt to realign the definition of "physiological" H(2)S concentrations upon which much of this exuberance has been established.

Abstract
Heme oxygenases (HOs) are the rate-limiting enzymes in the catabolism of heme into biliverdin, free iron, and carbon monoxide. Two genetically distinct isoforms of HO have been characterized: an inducible form, HO-1, and a constitutively expressed form, HO-2. HO-1 is a kind of stress protein, and thus regarded as a sensitive and reliable indicator of cellular oxidative stress. The HO system acts as potent antioxidants, protects endothelial cells from apoptosis, is involved in regulating vascular tone, attenuates inflammatory response in the vessel wall, and participates in angiogenesis and vasculogenesis. Endothelial integrity and activity are thought to occupy the central position in the pathogenesis of cardiovascular diseases. Cardiovascular disease risk conditions converge in the contribution to oxidative stress. The oxidative stress leads to endothelial and vascular smooth muscle cell dysfunction with increases in vessel tone, cell growth, and gene expression that create a pro-thrombotic/pro-inflammatory environment. Subsequent formation, progression, and obstruction of atherosclerotic plaque may result in myocardial infarction, stroke, and cardiovascular death. This background provides the rationale for exploring the potential therapeutic role for HO system in the amelioration of vascular inflammation and prevention of adverse cardiovascular outcomes.

Abstract
Beyond its vasodilator role, vascular nitric oxide (NO), which is synthesized by endothelial NO synthase (eNOS) via its activation, has been shown to play a number of other beneficial roles in the vascular system; it inhibits proliferation of vascular smooth muscle cells, prevents platelet aggregation, and regulates endothelial apoptosis. Such beneficial roles have been shown to be implicated in the regulation of endothelial functions. A loss of NO bioavailability that may result either from decreased eNOS expression and activity or from increased NO degradation is associated with endothelial dysfunction, a key factor in the development of vascular diseases. Heme oxygenase-1 (HO-1), an inducible enzyme, catalyzes the oxidative degradation of heme to free iron, carbon monoxide, and biliverdin, the latter being subsequently converted into bilirubin. In the vascular system, HO-1 and heme degradation products perform important physiological functions, which are ultimately linked to the protection of vascular cells. Studies have shown that HO-1 and heme degradation products exert vasodilatory, antioxidant, anti-inflammatory, antiproliferative and anti-apoptotic effects on vascular cells. Interestingly, these effects of HO-1 and its by-products are similar, at least in part, to those of eNOS-derived NO; this similarity may prompt investigators to study a possible relationship between eNOS-derived NO and HO-1 pathways. Many studies have been reported, and accumulating evidence suggests that HO-1 and heme degradation products can improve vascular function, at least in part, by compensating for the loss of NO bioavailability. This paper will provide the possible pathway explaining how HO-1 and heme degradation products can preserve vascular NO.

Abstract
Hydrogen sulfide (H(2)S), a volatile sulfur compound, is implicated as a cause of inflammation, especially when it is produced by bacteria colonizing gastrointestinal organs. However, it is unclear if H(2)S produced by periodontal pathogens affects the inflammatory responses mediated by oral/gingival epithelial cells. Therefore, the aims of this study were (1) to compare the in vitro production of H(2)S among 14 strains of oral bacteria and (2) to evaluate the effects of H(2)S on inflammatory response induced in host oral/gingival epithelial cells. Porphyromonas gingivalis (Pg) produced the most H(2)S in culture, which, in turn, resulted in the promotion of proinflammatory cytokine IL-8 from both gingival and oral epithelial cells. The up-regulation of IL-8 expression was reproduced by the exogenously applied H(2)S. Furthermore, the mutant strains of Pg that do not produce major soluble virulent factors, i.e. gingipains, still showed the production of H(2)S, as well as the promotion of epithelial IL-8 production, which was abrogated by H(2)S scavenging reagents. These results demonstrated that Pg produces a concentration of H(2)S capable of up-regulating IL-8 expression induced in gingival and oral epithelial cells, revealing a possible mechanism that may promote the inflammation in periodontal disease.
