Hydrogen Sulfide Downregulates Oncostatin M Expression via PI3K/Akt/NF-κB Signaling Processes in Neutrophil-like Differentiated HL-60 Cells. Antioxidants (Basel) 2023; 12:antiox12020417. [PMID: 36829975 PMCID: PMC9952767 DOI: 10.3390/antiox12020417] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 02/04/2023] [Accepted: 02/06/2023] [Indexed: 02/11/2023] Open
Abstract
The cytokine oncostatin M (OSM) is regarded as a critical mediator in various inflammatory responses. While the gaseous signaling molecule hydrogen sulfide (H2S) plays a role in a variety of pathophysiological conditions, such as hypertension, inflammatory pain, osteoarthritis, ischemic stroke, oxidative stress, retinal degeneration, and inflammatory responses, the underlying mechanism of H2S action on OSM expression in neutrophils needs to be clarified. In this work, we studied how H2S reduces OSM expression in neutrophil-like differentiated (d)HL-60 cells. To evaluate the effects of H2S, sodium hydrosulfide (NaHS, a donor that produces H2S), ELISA, real-time PCR (qPCR), immunoblotting, and immunofluorescence staining were utilized. Although exposure to granulocyte-macrophage colony-stimulating factor (GM-CSF) resulted in upregulated levels of production and mRNA expression of OSM, these upregulated levels were reduced by pretreatment with NaHS in dHL-60 cells. Similarly, the same pretreatment lowered phosphorylated levels of phosphatidylinositol 3-kinase, Akt, and nuclear factor-kB that had been elevated by stimulation with GM-CSF. Overall, our results indicated that H2S could be a therapeutic agent for inflammatory disorders via suppression of OSM.

Dilek N, Papapetropoulos A, Toliver-Kinsky T, Szabo C. Hydrogen sulfide: An endogenous regulator of the immune system. Pharmacol Res 2020; 161:105119. [PMID: 32781284 DOI: 10.1016/j.phrs.2020.105119] [Citation(s) in RCA: 128] [Impact Index Per Article: 32.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 07/30/2020] [Accepted: 07/30/2020] [Indexed: 12/12/2022]
Abstract
Hydrogen sulfide (H2S) is now recognized as an endogenous signaling gasotransmitter in mammals. It is produced by mammalian cells and tissues by various enzymes - predominantly cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3-MST) - but part of the H2S is produced by the intestinal microbiota (colonic H2S-producing bacteria). Here we summarize the available information on the production and functional role of H2S in the various cell types typically associated with innate immunity (neutrophils, macrophages, dendritic cells, natural killer cells, mast cells, basophils, eosinophils) and adaptive immunity (T and B lymphocytes) under normal conditions and as it relates to the development of various inflammatory and immune diseases. Special attention is paid to the physiological and the pathophysiological aspects of the oral cavity and the colon, where the immune cells and the parenchymal cells are exposed to a special "H2S environment" due to bacterial H2S production. H2S has many cellular and molecular targets. Immune cells are "surrounded" by a "cloud" of H2S, as a result of endogenous H2S production and exogenous production from the surrounding parenchymal cells, which, in turn, importantly regulates their viability and function. Downregulation of endogenous H2S producing enzymes in various diseases, or genetic defects in H2S biosynthetic enzyme systems either lead to the development of spontaneous autoimmune disease or accelerate the onset and worsen the severity of various immune-mediated diseases (e.g. autoimmune rheumatoid arthritis or asthma). Low, regulated amounts of H2S, when therapeutically delivered by small molecule donors, improve the function of various immune cells, and protect them against dysfunction induced by various noxious stimuli (e.g. reactive oxygen species or oxidized LDL). These effects of H2S contribute to the maintenance of immune functions, can stimulate antimicrobial defenses and can exert anti-inflammatory therapeutic effects in various diseases.

β-eudesmol inhibits thymic stromal lymphopoietin through blockade of caspase-1/NF-κB signal cascade in allergic rhinitis murine model. Chem Biol Interact 2018; 294:101-106. [PMID: 30148989 DOI: 10.1016/j.cbi.2018.08.026] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2018] [Revised: 07/27/2018] [Accepted: 08/23/2018] [Indexed: 12/30/2022]
Abstract
Allergic rhinitis (AR) is a global health problem because of its steadily increasing incidence and prevalence that currently affects about 30% of people worldwide. β-eudesmol has various beneficial effects, including anti-cancer and anti-allergic activities. However, the effects of β-eudesmol on AR have not yet been clarified; thus, we investigated the effects of β-eudesmol in an ovalbumin-induced AR animal model using enzyme-linked immunosorbent assay, histamine assay, Western blotting, and hematoxylin and eosin staining methods. β-eudesmol reduced the nasal rubs score and levels of histamine and immunoglobulin E in serum of AR mouse. In addition, the levels of thymic stromal lymphopoietin, interleukin-1β, tumor necrosis factor-α, and macrophage inflammatory protein-2 were down-regulated and infiltration of eosinophils and the level of intercellular adhesion molecule-1 were inhibited by β-eudesmol administration. β-eudesmol administration also reduced active caspase-1 and nuclear factor-κB DNA binding activity in nasal mucosa tissues of AR mice. Taken together, these results indicate that β-eudesmol would be effective for the treatment of allergic and inflammatory diseases, such as AR.

Effects of Linalyl Acetate on Thymic Stromal Lymphopoietin Production in Mast Cells. Molecules 2018; 23:molecules23071711. [PMID: 30011850 PMCID: PMC6100028 DOI: 10.3390/molecules23071711] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Revised: 07/06/2018] [Accepted: 07/12/2018] [Indexed: 12/31/2022] Open
Abstract
Thymic stromal lymphopoietin (TSLP) is an important factor responsible for the pathogenesis of allergic diseases, such as atopic dermatitis and asthma. Because linalyl acetate (LA) possesses a wide range of pharmacological properties, being antispasmodic, anti-inflammatory, and anti-hyperpigmentation, we hypothesized that LA could inhibit TSLP. Therefore, enzyme-linked immunosorbent assay, quantitative polymerase chain reaction, caspase-1 assay, Western blot analysis, fluorescent analyses of the intracellular calcium levels, and the phorbol myristate acetate (PMA)-induced edema model were used to investigate how LA inhibits the production of TSLP in HMC-1 cells. LA reduced the production and mRNA expression of TSLP in HMC-1 cells. LA also inhibited the activation of nuclear factor-κB and degradation of IκBα. PMA plus A23187 stimulation up-regulated caspase-1 activity in HMC-1 cells; however, this up-regulated caspase-1 activity was down-regulated by LA. Finally, LA decreased intracellular calcium levels in HMC-1 cells as well as PMA-induced ear swelling responses in mice. Taken together, these results suggest that LA would be beneficial to treatment of atopic and inflammatory diseases by reducing TSLP.

Abstract
We evaluated the performance of laser ablation analysis techniques such as laser-induced breakdown spectroscopy (LIBS), laser ablation inductively coupled optical emission spectrometry (LA-ICP-OES), and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), in comparison with that of ICP-OES using aqueous solutions for the quantification of sulfur (S) in edible salts from different geographical origins. We found that the laser ablation based sampling techniques were not influenced by loss of S, which was observed in ICP-OES with aqueous solutions for a certain salt upon their dissolution in aqueous solutions, originating from the formation of volatile species and precipitates upon their dilution in water. Although detection of S using direct laser sampling with LA-ICP-MS has well-known isobaric and polyatomic interferences, LIBS and LA-ICP-OES showed good accuracy in the detection of S for all salts. LIBS also provided the ability to identify the dominant chemical form in which S is present in salts. Correlation between S and oxygen, observed in LIBS spectra, provided chemical information about the presence of S2- or [Formula: see text], which are associated with the origin and quality of edible salts.
