Book excerpt: Methods in Redox Signaling is the first and only comprehensive handbook on the experimental methods used to study redox signaling. Formerly recognized as destructive mechanisms, reactive oxygen species (ROS) have now been recognized as saviors by protecting the cells through redox signaling. This evolving science involves the pathobiology of various disease processes including cancer, cardiovascular diseases, wound healing, and many other degenerative diseases. Although the concept of reactive oxygen species has been known to some for decades, their potential role in the biological system has only been recognized in recent years. With the identification of these new mechanisms and their potential, the exploration in this area is expanding rapidly and the scientific articles are pouring in. Being relatively young, a vast majority of the mechanisms of redox signaling, especially those related to disease processes still remain unknown. Methods in Redox Signaling provides a valuable tool for the growing number of scientists engaging in the research and investigation involving redox regulation of degenerative diseases.

Download or read book Redox Signaling and Biomarkers in Ageing written by Ufuk Çakatay and published by Springer Nature. This book was released on 2021-12-02 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to present the age-related alterations in redox signaling networks and their diagnostic biomarkers in aging cells using multidisciplinary approach. Establishing sensitive and specific biomarkers of dynamic redox homeostasis is crucially important in the development of effective antiaging and senolytic interventions. Recent years have seen tremendous advances in the understanding of redox signaling events which highlight the process of aging and age-related pathologies. A major challenge in biological aging research is developing reliable biomarkers to determine the consequences of disrupted redox signaling networks long before the clinical diagnosis of age-related diseases is made. Therefore, we have chosen to concentrate on aging-induced aberrant redox signaling networks, their biomarkers, and pathological consequences in this book. Although oxidation is a natural metabolic process, the imbalance in the level of oxidants and antioxidants causes oxidative stress and eventually leads to inflammatory conditions, diabetes, neurodegenerative diseases, and cancer. Novel redox-sensitive biomarkers for the evaluation of aging-induced proteinopathies such as amyloid ß and tau proteins in Alzheimer's disease, α-synuclein in Parkinson's disease, and islet amyloid polypeptides in type 2 diabetes mellitus recently drew the attention of researchers. Inside this textbook, readers will find comprehensive perspectives on the association between redox homeostasis and the aging process both at the molecular and clinical levels. Due to the inherent relationship between impaired metabolic activities and oxidative stress, the temporal interaction between intermediary metabolism and disturbed redox status can lead to greater susceptibility to aging-induced diseases and disorders, such as cardiovascular diseases, hypertension, and diabetes. This knowledge could be a key to continued research toward improving medication regimens such as in cancer and cardiovascular therapies, and procedural outcomes for patients. This book brings together current research evidence and knowledge on redox signaling and biomarkers in aging in chapters written by leading global experts in this rapidly evolving field. We hope that this textbook is of interest to a wide group of researchers, advanced students, scientifically curious non-specialist readers and clinicians alike.

Download or read book Oxidative Stress and Redox Regulation written by Ursula Jakob and published by Springer Science & Business Media. This book was released on 2013-03-15 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many physiological conditions such as host defense or aging and pathological conditions such as neurodegenerative diseases, and diabetes are associated with the accumulation of high levels of reactive oxygen species and reactive nitrogen species. This generates a condition called oxidative stress. Low levels of reactive oxygen species, however, which are continuously produced during aerobic metabolism, function as important signaling molecules, setting the metabolic pace of cells and regulating processes ranging from gene expression to apoptosis. For this book we would like to recruit the experts in the field of redox chemistry, bioinformatics and proteomics, redox signaling and oxidative stress biology to discuss how organisms achieve the appropriate redox balance, the mechanisms that lead to oxidative stress conditions and the physiological consequences that contribute to aging and disease.

Download or read book New Methods for Detecting Biomarkers of Oxidative Stress and Redox Signaling on Protein Cysteine Residues written by Erika Bechtold and published by . This book was released on 2010 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both nitric oxide and hydrogen peroxide, as well as their respective metabolites (reactive nitrogen or oxygen species), participate in a variety of cellular redox processes and have become well recognized as messengers in cellular signal transduction. One important mechanism by which cellular redox-based signaling occurs is reversible oxidation of cysteine residues in the presence of low concentrations of these oxidants. SNitrosothiols (RSNO) and sulfenic acids (RSOH) are thought to be two of the most common cysteine modifications, and formation of these species reversibly alters protein function. Protein oxidation is studied to a lesser extent than lipid and DNA oxidation in part because of a lack of sensitive, stable, readily detectable markers for tracking these unstable intermediates. We addressed the specificity of current RSNO detection methods, including the Biotin Switch Technique, using a mutated C165S alkyl hydroperoxide reductase (AhpC) enzyme from Salmonella typhimurium. Through both SDS PAGE and MS-based methods, we showed that the thiol alkylating agents used during this assay had an unexpected cross-reactivity with our model sulfenic acid, and in all cases formed covalent sulfoxide products. This cross-reactivity suggests that the Biotin Switch Technique may quantify both -SNO and -SOH versions of our enzyme, questioning the reliability of this assay. We also report the development of new chemical probes for the detection of Snitrosothiols and sulfenic acids. Using the water-soluble phosphine, tris(4,6-dimethyl-3-sulfonatophenyl)phosphine trisodium salt hydrate (TXPTS), we covalently labeled S-nitrosated cysteine, glutathione, and C165S AhpC. A combination of NMR and MS techniques reveals that these reactions produce covalent S-alkylphosphonium ion adducts (with S-P connectivity), TXPTS oxide, and a TXPTS-derived aza-ylide. Mechanistically, this reaction may proceed through an S-substituted aza-ylide or the direct displacement of nitroxyl from the RSNO group. This work provides a new means for detecting and quantifying S-nitrosated species in solution and highlights the role of triaryl phosphines as a new tools to elucidate the role of S-nitrosothiols in nitric oxide metabolism. The synthesis of novel dimedone-based chemical probes for the detection of protein sulfenic acids are also presented. These probes all contain a dimedone-based 1,3-cyclohexadione core, which covalently binds RSOHs, and reporter tags such as biotin for affinity capture and fluorescent labels for visual detection of cellular sulfenic acids. The application of these new chemical probes has improved our understanding of the role of sulfenicacid formation in a variety of cellular processes. These new probes have been used to monitor protein oxidation events in models of the immune response, angiogenesis, and cancer signaling pathways and have enhanced our understanding of the biological roles of hydrogen peroxide and other cellular ROS in signal transduction.

Download or read book Oxidants and Redox Signaling in Inflammation written by Gabor Csanyi and published by Frontiers Media SA. This book was released on 2019-07-10 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last two decades, our view of the role of reactive oxygen species (ROS) in inflammatory processes has changed dramatically. ROS that are constantly produced at lower levels by living cells metabolizing oxygen contribute to normal cellular function and tissue homeostasis. ROS are produced at higher levels in inflammation and regulate the inflammatory response in specific ways. The role of ROS in inflammation is complex and primarily determined by their relative amount, chemical properties, reactivity, subcellular localization and molecular environment, specificity for their biological targets, and availability and mechanisms of antioxidant defense systems. This eBook comprises twelve reviews and original articles that provide new findings on the role of ROS in the regulation of inflammatory processes, highlight emerging topics in redox signaling, describe new ROS detection techniques and discuss alternative therapeutic strategies to treat inflammatory disorders. The editorial that precedes the published articles briefly summarizes the main findings of each research paper. We hope that this collection of research articles contribute to a better understanding of ROS in inflammation.

Download or read book Redox Signaling in Neurodegenerative Diseases Biomarkers Targets and Therapies written by Andreia Neves Carvalho and published by Frontiers Media SA. This book was released on 2023-05-16 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Redox homeostasis results from the balance between the production of reactive species (e.g. ROS, RNS, etc) and their detoxification by endogenous or exogenous antioxidants. ROS play several important physiological roles, however, their excessive production or impaired detoxification is associated with oxidative stress and cellular injury. Importantly, oxidative damage to vulnerable central nervous system (CNS) cells is a common pathological feature of several neurodegenerative diseases. Antioxidants have been considered as attractive potential therapeutic agents to prevent or halt disease progression but the clinical efficacy of antioxidant treatment strategies is still marginal. Improvement of antioxidant therapy effectiveness might involve adjustment of preclinical to clinical settings and development of new efficient delivery methods and will require a more in-depth knowledge of cellular redox-signaling mechanisms. Promising novel redox-based therapeutic strategies are gaining relevance to combat oxidative stress associated with neurodegenerative diseases. These include boosting the endogenous antioxidant machinery through activation of the antioxidant master regulator Nrf2 (nuclear factor erythroid 2-related factor 2) or modulation of ROS production by NOX (nicotinamide adenine dinucleotide phosphate (NADPH) oxidase) inhibitors. Redox regulation of key cellular functions is currently recognized as an important cellular signaling mechanism and events such as post-translational modifications (e.g. S_glutathionylation, S_nitrosylation, glycosylation, etc) play important roles in redox signal transduction and might be instrumental to uncover pathological mechanisms and identify novel therapeutic targets in neurodegenerative diseases. This Research Topic focuses on redox signaling mechanisms and aims to provide novel insights into the role of redox-signaling, with particular emphasis on redox regulation involving post-translational modifications, in the pathophysiology of neurodegenerative diseases. Moreover, it aims to present an overview of the potential of antioxidants as therapeutics for CNS disorders with a special focus on emerging novel therapeutic redox-based strategies. We are particularly interested in studies: -addressing new redox-based molecular mechanisms contributing to neurodegenerative diseases; -exploring the role of naturally occurring compounds, standard medications, and nutraceuticals with antioxidant properties in modulating redox-signaling pathways and limiting and/or preventing oxidative damage associated with these disorders; -addressing mechanistically the role of post-translational modifications in the pathophysiology of neurodegenerative disorders.
