Hydrogen sulfide-induced hypometabolism prevents renal ischemia/reperfusion injury.

ABSTRACT: Hydrogen sulfide (H(2)S) can induce a hypometabolic, hibernation-like state in mammals when given in subtoxic concentrations. Pharmacologically reducing the demand for oxygen is a promising strategy to minimize unavoidable hypoxia-induced injury such as ischemia/reperfusion injury during renal transplantation. Here we show that H(2)S reduces metabolism in vivo, ex vivo, and in vitro. Furthermore, we demonstrate the beneficial effects of H(2)S-induced hypometabolism in a model of bilateral renal ischemia/reperfusion injury using three different treatment strategies. The results demonstrate striking protective effects on survival, renal function, apoptosis, and inflammation. A hypometabolic state induced by H(2)S might have therapeutic potential to protect kidneys that suffer from hypoxia.

Role of Hydrogen Sulfide in Ischemia-Reperfusion Injury.

Project description:Ischemia-reperfusion (I/R) injury is one of the major causes of high morbidity, disability, and mortality in the world. I/R injury remains a complicated and unresolved situation in clinical practice, especially in the field of solid organ transplantation. Hydrogen sulfide (H2S) is the third gaseous signaling molecule and plays a broad range of physiological and pathophysiological roles in mammals. H2S could protect against I/R injury in many organs and tissues, such as heart, liver, kidney, brain, intestine, stomach, hind-limb, lung, and retina. The goal of this review is to highlight recent findings regarding the role of H2S in I/R injury. In this review, we present the production and metabolism of H2S and further discuss the effect and mechanism of H2S in I/R injury.

Recombinant thrombomodulin prevents acute lung injury induced by renal ischemia-reperfusion injury.

Project description:Acute kidney injury (AKI) complicated by acute lung injury has a detrimental effect on mortality among critically ill patients. Recently, a renal ischemia-reperfusion (IR) model suggested the involvement of histones and neutrophil extracellular traps (NETs) in the development of distant lung injury after renal IR. Given that recombinant thrombomodulin (rTM) has anti-inflammatory roles by binding to circulating histones, we aimed to clarify its effect on distant lung injury induced by AKI in a murine bilateral renal IR model. Both pretreatment and delayed treatment with rTM significantly decreased pulmonary myeloperoxidase activity, but they did not affect renal dysfunction at 24?h after renal IR. Additionally, rTM mitigated the renal IR-augmented expression of proinflammatory cytokines (tumor necrosis factor-?, interleukin-6, and keratinocyte-derived chemokine), and vascular leakage, as well as the degree of lung damage. Intense histone accumulation and active NET formation occurred in both the kidneys and the lungs; however, rTM significantly decreased the histone and NET accumulation only in the lungs. Administration of rTM may have protective impact on the lungs after renal IR by blocking histone and NET accumulation in the lungs, although no protection was observed in the kidneys. Treatment with rTM may be an adjuvant strategy to attenuate distant lung injury complicating AKI.

MicroRNA-24 antagonism prevents renal ischemia reperfusion injury.

Project description:Ischemia-reperfusion (I/R) injury of the kidney is a major cause of AKI. MicroRNAs (miRs) are powerful regulators of various diseases. We investigated the role of apoptosis-associated miR-24 in renal I/R injury. miR-24 was upregulated in the kidney after I/R injury of mice and in patients after kidney transplantation. Cell-sorting experiments revealed a specific miR-24 enrichment in renal endothelial and tubular epithelial cells after I/R induction. In vitro, anoxia/hypoxia induced an enrichment of miR-24 in endothelial and tubular epithelial cells. Transient overexpression of miR-24 alone induced apoptosis and altered functional parameters in these cells, whereas silencing of miR-24 ameliorated apoptotic responses and rescued functional parameters in hypoxic conditions. miR-24 effects were mediated through regulation of H2A histone family, member X, and heme oxygenase 1, which were experimentally validated as direct miR-24 targets through luciferase reporter assays. In vitro, adenoviral overexpression of miR-24 targets lacking miR-24 binding sites along with miR-24 precursors rescued various functional parameters in endothelial and tubular epithelial cells. In vivo, silencing of miR-24 in mice before I/R injury resulted in a significant improvement in survival and kidney function, a reduction of apoptosis, improved histologic tubular epithelial injury, and less infiltration of inflammatory cells. miR-24 also regulated heme oxygenase 1 and H2A histone family, member X, in vivo. Overall, these results indicate miR-24 promotes renal ischemic injury by stimulating apoptosis in endothelial and tubular epithelial cell. Therefore, miR-24 inhibition may be a promising future therapeutic option in the treatment of patients with ischemic AKI.

Slit2 prevents neutrophil recruitment and renal ischemia-reperfusion injury.

Project description:Neutrophils recruited to the postischemic kidney contribute to the pathogenesis of ischemia-reperfusion injury (IRI), which is the most common cause of renal failure among hospitalized patients. The Slit family of secreted proteins inhibits chemotaxis of leukocytes by preventing activation of Rho-family GTPases, suggesting that members of this family might modulate the recruitment of neutrophils and the resulting IRI. Here, in static and microfluidic shear assays, Slit2 inhibited multiple steps required for the infiltration of neutrophils into tissue. Specifically, Slit2 blocked the capture and firm adhesion of human neutrophils to inflamed vascular endothelial barriers as well as their subsequent transmigration. To examine whether these observations were relevant to renal IRI, we administered Slit2 to mice before bilateral clamping of the renal pedicles. Assessed at 18 hours after reperfusion, Slit2 significantly inhibited renal tubular necrosis, neutrophil and macrophage infiltration, and rise in plasma creatinine. In vitro, Slit2 did not impair the protective functions of neutrophils, including phagocytosis and superoxide production, and did not inhibit neutrophils from killing the extracellular pathogen Staphylococcus aureus. In vivo, administration of Slit2 did not attenuate neutrophil recruitment or bacterial clearance in mice with ascending Escherichia coli urinary tract infections and did not increase the bacterial load in the livers of mice infected with the intracellular pathogen Listeria monocytogenes. Collectively, these results suggest that Slit2 may hold promise as a strategy to combat renal IRI without compromising the protective innate immune response.

Hydrogen sulfide attenuates myocardial ischemia-reperfusion injury by preservation of mitochondrial function.

Project description:The recent discovery that hydrogen sulfide (H(2)S) is an endogenously produced gaseous second messenger capable of modulating many physiological processes, much like nitric oxide, prompted us to investigate the potential of H(2)S as a cardioprotective agent. In the current study, we demonstrate that the delivery of H(2)S at the time of reperfusion limits infarct size and preserves left ventricular (LV) function in an in vivo model of myocardial ischemia-reperfusion (MI-R). This observed cytoprotection is associated with an inhibition of myocardial inflammation and a preservation of both mitochondrial structure and function after I-R injury. Additionally, we show that modulation of endogenously produced H(2)S by cardiac-specific overexpression of cystathionine gamma-lyase (alpha-MHC-CGL-Tg mouse) significantly limits the extent of injury. These findings demonstrate that H(2)S may be of value in cytoprotection during the evolution of myocardial infarction and that either administration of H(2)S or the modulation of endogenous production may be of clinical benefit in ischemic disorders.

Controllable hydrogen sulfide donors and their activity against myocardial ischemia-reperfusion injury.

Project description:Hydrogen sulfide (H2S), known as an important cellular signaling molecule, plays critical roles in many physiological and/or pathological processes. Modulation of H2S levels could have tremendous therapeutic value. However, the study on H2S has been hindered due to the lack of controllable H2S releasing agents that could mimic the slow and moderate H2S release in vivo. In this work we report the design, synthesis, and biological evaluation of a new class of controllable H2S donors. Twenty-five donors were prepared and tested. Their structures were based on a perthiol template, which was suggested to be involved in H2S biosynthesis. H2S release mechanism from these donors was studied and proved to be thiol-dependent. We also developed a series of cell-based assays to access their H2S-related activities. H9c2 cardiac myocytes were used in these experiments. We tested lead donors' cytotoxicity and confirmed their H2S production in cells. Finally we demonstrated that selected donors showed potent protective effects in an in vivo murine model of myocardial ischemia-reperfusion injury, through a H2S-related mechanism.

Glutamine attenuates renal ischemia-reperfusion injury and prevents acute kidney damage

Project description:Acute kidney injury (AKI) represents a common complication in critically ill patients that is associated with an increased morbidity and mortality. Currently, no effective treatment options are available. Here, we show that glutamine significantly attenuates leukocyte recruitment and inflammatory signaling in human and murine tubular epithelial cells (TECs). In a murine AKI model induced by ischemia-reperfusion-injury (IRI) we show that glutamine causes transcriptomic and proteomic reprogramming in renal TECs and neutrophils, resulting in decreased epithelial apoptosis, neutrophil recruitment and improved mitochondrial functionality and respiration provoked by an ameliorated oxidative phosphorylation. We identify the proteins glutamine gamma glutamyltransferase 2 (Tgm2) and apoptosis signal-regulating kinase (Ask1) as the major targets of glutamine in apoptotic signaling. Increased Tgm2 expression and reduced Ask1 activation result in decreased JNK activation leading to a diminished mitochondrial intrinsic apoptosis in kidneys upon IRI-induced AKI and under hypoxia or following TNFα-treatment of TECs. Consequently, glutamine administration attenuated kidney injury in vivo during AKI progression as well as TEC viability in vitro under inflammatory and hypoxic conditions.

A Long-Term and Slow-Releasing Hydrogen Sulfide Donor Protects against Myocardial Ischemia/Reperfusion Injury.

Project description:Hydrogen sulfide (H2S) has been recognized as an important gasotransmitter exerting various physiological effects, especially in the cardiovascular system. Herein we investigated the cardioprotective effects of a novel long-term and slow-releasing H2S donor, DATS-MSN, using in vivo myocardial ischemia/reperfusion (I/R) models and in vitro hypoxia/reoxygenation cardiomyocyte models. Unlike the instant-releasing pattern of sodium hydrosulphide (NaHS), the release of H2S from DATS-MSN was quite slow and continuous both in the cell culture medium and in rat plasma (elevated H2S concentrations during 24 h and 72 h reperfusion). Correspondingly, DATS-MSN demonstrated superior cardioprotective effects over NaHS in I/R models, which were associated with greater survival rates, reduced CK-MB and troponin I levels, decreased cardiomyocyte apoptosis index, increased antioxidant enzyme activities, inhibited myocardial inflammation, greater reduction in the infarct area and preserved cardiac ejection fraction. Some of these effects of DATS-MSN were also found to be superior to classic slow-releasing H2S donor, GYY4137. In in vitro experiments, cardiomyocytes injury was also found to be relived with the use of DATS-MSN compared to NaHS after the hypoxia/reoxygenation processes. The present work provides a novel long-term and slow-releasing H2S donor and an insight into how the release patterns of H2S donors affect its physiological functionality.

Inhibition of renal rho kinase attenuates ischemia/reperfusion-induced injury.

Project description:The Rho kinase pathway plays an important role in dedifferentiation of epithelial cells and infiltration of inflammatory cells. For testing of the hypothesis that blockade of this cascade within the kidneys might be beneficial in the treatment of renal injury the Rho kinase inhibitor, Y27632 was coupled to lysozyme, a low molecular weight protein that is filtered through the glomerulus and is reabsorbed in proximal tubular cells. Pharmacokinetic studies with Y27632-lysozyme confirmed that the conjugate rapidly and extensively accumulated in the kidney. Treatment with Y27632-lysozyme substantially inhibited ischemia/reperfusion-induced tubular damage, indicated by reduced staining of the dedifferentiation markers kidney injury molecule 1 and vimentin, and increased E-cadherin relative to controls. Rho kinase activation was inhibited by Y27632-lysozyme within tubular cells and the interstitium. Y27632-lysozyme also inhibited inflammation and fibrogenesis, indicated by a reduction in gene expression of monocyte chemoattractant protein 1, procollagen Ialpha1, TGF-beta1, tissue inhibitor of metalloproteinase 1, and alpha-smooth muscle actin. Immunohistochemistry revealed reduced macrophage infiltration and decreased expression of alpha-smooth muscle actin, collagen I, collagen III, and fibronectin. In contrast, unconjugated Y27632 did not have these beneficial effects but instead caused systemic adverse effects, such as leukopenia. Neither treatment improved renal function in the bilateral ischemia/reperfusion model. In conclusion, the renally targeted Y27632-lysozyme conjugate strongly inhibits tubular damage, inflammation, and fibrogenesis induced by ischemia/reperfusion injury.
