Download or read book Oxidative Stress and Redox Signalling in Parkinson s Disease written by Rodrigo Franco and published by Royal Society of Chemistry. This book was released on 2017-07-25 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parkinson's Disease is the second most common neurodegenerative disorder affecting millions of people worldwide. In order to find neuroprotective strategies, a clear understanding of the mechanisms involved in the dopaminergic death of cells that progresses the disease is needed. Oxidative stress can be defined as an imbalance between the production of reactive species and the ability to detoxify them and their intermediates or by-products. Oxidative damage to lipids, proteins, and DNA has been detected in autopsies from individuals with Parkinson’s Disease and so links can be made between oxidative stress and Parkinson’s Disease pathogenesis. This book provides a thorough review of the mechanisms by which oxidative stress and redox signalling mediate Parkinson’s Disease. Opening chapters bring readers up to speed on basic knowledge regarding oxidative stress and redox signalling, Parkinson’s Disease, and neurodegeneration before the latest advances in this field are explored in detail. Topics covered in the following chapters include the role of mitochondria, dopamine metabolism, metal homeostasis, inflammation, DNA-damage and thiol-signalling. The role of genetics and gene-environment interactions are also explored before final chapters discuss the identification of potential biomarkers for diagnosis and disease progression and the future of redox/antioxidant based therapeutics. Written by recognized experts in the field, this book will be a valuable source of information for postgraduate students and academics, clinicians, toxicologists and risk assessment groups. Importantly, it presents the current research that might later lead to redox or antioxidant – based therapeutics for Parkinson’s disease.
Download or read book Oxidative Stress and Neurodegenerative Disorders written by G. Ali Qureshi and published by Elsevier. This book was released on 2007-03-22 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidative stress is the result of an imbalance in pro-oxidant/antioxidant homeostasis that leads to the generation of toxic reactive oxygen species. Brain cells are continuously exposed to reactive oxygen species generated by oxidative metabolism, and in certain pathological conditions defense mechanisms against oxygen radicals may be weakened and/or overwhelmed. DNA is a potential target for oxidative damage, and genomic damage can contribute to neuropathogenesis. It is important therefore to identify tools for the quantitative analysis of DNA damage in models on neurological disorders. This book presents detailed information on various neurodegenerative disorders and their connection with oxidative stress. This information will provide clinicians with directions to treat these disorders with appropriate therapy and is also of vital importance for the drug industries for the design of new drugs for treatment of degenerative disorders.* Contains the latest information on the subject of neurodegenerative disorders* Reflects on various factors involved in degeneration and gives suggestions for how to tackle these problems
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.
Download or read book Oxidative Stress and Neuroprotection written by S.H. Parvez and published by Springer Science & Business Media. This book was released on 2006-12-26 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with basic and clinical aspects of monoamine oxidase (MAO) subtypes A and B highlighting its importance in neurological and psychiatric diseases. Consequently the therapeutic actions of MAO-A and -B inhibitors in Parkinson’s disease (PK) and depression are the focus of several chapters. As MAO is the basis of the development of the "oxidative stress hypothesis" of PD, several chapters are devoted to iron and iron-induced oxidative stress in various experimental studies and clinical conditions. Based on these findings, new compounds have been developed which not only block MAO, but are in addition, either inhibitors of acetylcholine esterase or have iron chelating properties. The aspect of "preclinical" and "clinical" neuro protection as well as MAO neuroprotection are additional topics covered in this book. MAO, iron and neuroprotection are seen in the framework of general anti Parkinson’s therapy with chapters on levodopa, dopaminergic receptor agonists and clinical issues.

Download or read book Oxidative Stress and Free Radical Damage in Neurology written by Natan Gadoth and published by Springer Science & Business Media. This book was released on 2010-11-19 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of free radicals and oxidative stress in neurological disorders has only recently been recognized, leaving clinical neurologists to seek in vain for information on the subject even in major textbooks. What published information there is may consist of brief reminders of the possible association of superoxidase dismutase with familial amyotrophic lateral sclerosis and nitrous oxide with migraine. With luck they may also find information on the purported role of free radicals in the pathogenesis of traumatic brain injury. Oxidative Stress and Free Radical Damage in Neurology sets the record straight, focusing on clinical and research issues regarding the interplay of free radicals and the human nervous system. Crucially, the chapters cover numerous antioxidants and their possible therapeutic role in neurological disorders. Key illnesses such as epilepsy, multiple sclerosis and Parkinson’s are analyzed, and chapters also examine more general issues such as the link between free radicals and inflammation of the central nervous system. Clinicians and laboratory researchers alike will find that this book augments their understanding not only of the widespread involvement of free radicals in the central nervous system but also of some uncertainties surrounding whether free radical damage in neurology plays a primary or secondary role.
Download or read book Understanding the Mechanism of Oxidative Stress Generation by Oxidized Dopamine Metabolites written by Nihar Mehta and published by . This book was released on 2017 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dopamine oxidation product cysteinyl-dopamine has attracted attention as a contributor to the death of dopaminergic neurons in Parkinson's disease. Treatment of cysteinyl-dopamine with hypochlorite yields an even more cytotoxic product. This product, HOCD, has potent redox-cycling activity and initiates production of superoxide in PC12 cells. Taurine, which scavenges hypochlorite, protects PC12 cells from cysteinyl-dopamine but not from HOCD, suggesting that HOCD, not cysteinyl-dopamine itself, is toxic. Furthermore, rotenone, which enhances expression of the hypochlorite-producing enzyme myeloperoxidase, increases the cytotoxicity of cysteinyl-dopamine but not of HOCD. This suggests that dopamine oxidation to cysteinyl-dopamine followed by hypochlorite-dependent conversion to a cytotoxic redox-cycling product HOCD, leads to the generation of reactive oxygen species and oxidative stress and may contribute to the death of dopaminergic neurons. Our findings of HOCD toxicity in PC12 cells was followed by our study to determine the mode of cell death. The morphological changes in the cell such as membrane blebbing and appearance of biochemical markers such as cleaved poly-ADP ribose polymerase and active caspase-9 suggested cell death by apoptosis. Moreover, increased expression of tumor suppressor protein p53, indicated mitochondrial mediated apoptotic cell death. Our observations have raised an unappreciated possibility that may link dopamine oxidation, microglial inflammation, oxidative stress and the rotenone model of Parkinson's disease. Furthermore, it offers a promising new approach in the search for a therapeutic cure for Parkinson's disease.
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 Neural Injury written by Sigrid C. Veasey and published by Springer Science & Business Media. This book was released on 2009-05-28 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty-five years ago, Earl R. Stadtman, PhD discovered that specific enzymes regulating metabolism can be inactivated by oxidation [1]. He later showed that age-related oxidative modification contributes, at least in part, to age-related loss of function of the enzymes [2, 3]. Dr. Stadtman broke the ground for a new field of study to discover how oxidative stress contributes in significant ways to age-related cellular dysfunction and protein accumulation and that oxidation in the aging brain influences Alzheimer’s disease, ischemia-reperfusion injury, amyotrophic lateral sclerosis, and lifespan [4–6]. Today, his research and mentorship have positively influenced the work of hundreds of scientists in this field. We dedicate this book to Dr. Earl R. Stadtman (1912–2008), in celebration of his passion for science and his superior collaborative and mentorship skills. This book is comprised of three sections. The first describes the valuable roles reactive oxygen species (ROS) and reactive nitrogen species (RNS) play in cellular biology. The second section provides an overview of redox imbalance injury with effects on mitochondria, signaling, endoplasmic reticular function, and on aging in general. The third section takes these mechanisms to neurodegenerative disorders and provides a state-of-the-art look at the roles redox imbalances play in age-related susceptibility to disease and in the disease processes. In the first section we attempt to answer a question posed by Dr. Stadtman, ‘‘Why have cells selected reactive oxygen species to regulate cell signaling events’’ [7].

Download or read book Oxidation Damage in Parkinson s Disease written by and published by . This book was released on 2003 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of the proposal was to provide a detailed assessment of the role of oxidative damage in Parkinson's Disease (PD) postmortem brain tissue, body fluids of PD patients and in the MPTP model. There were trends towards increased oxidative damage markers in post mortem brain tissue of PD patients and a number of specific genes linked to oxidative stress were reduced in expression. There was increased lipid peroxidation in progressive supranuclear palsy brains. There were no significant alterations in 8-hydroxy-2- deoxyguanosine in the plasma of PD patients. We found that overexpression of manganese superoxide dismutase attenuated MPTP toxicity whereas its deficiency exacerbated detoxicity. Similarly, a deficiency of glutathione peroxidase exacerbated MPTP neurotoxicity. Overexpression of Bcl2 or a dominant-negative mutant of interleukin-l converting enzymes significantly attenuated MPTP toxicity. We found increases in oxidative damage markers in the substantia nigra of MPTP treated baboons. A number of free radical spintraps as well as a selective inhibitor of neuronal nitric oxide synthase protected against MPTP neurotoxicity. In summary, our studies showed further evidence linking oxidative damage to dopaminergic neurons in the substantia nigra as well as in the MPTP model of PD.
