Book excerpt: Due to that at present, the majority of diseases are associated with alterations in oxidative stress and inflammatory processes, and in that Nrf-2 is a modulator of these processes; knowing how this transcriptional factor functions and is regulated opens a therapeutic window to diverse diseases. Therefore, the efforts of various investigation groups are centered on finding activators and/or inhibitors of Nrf-2 to prevent or control diverse diseases, for example, cancer, where it would be important to regulate Nrf-2 in order for it to activate apoptosis pathways in cancerogenous cells, or in neurodegenerative diseases where cell death is predominant, it would be important for Nrf-2 to activate antiapoptotic pathways.

Book excerpt: Regulation of cellular redox homeostasis determines the fate of the cell. Perturbation in redox status is known to elicit multiple cellular pathways. Role of oxidative stress modulation in channelizing the cell towards apoptosis or rescuing the cell by activating pro-survival pathways, depends on the levels of generated oxidative stress. High levels of generated oxidative stress induce cell death pathways whereas mild and low levels are known to elicit the cell survival pathways. Generation of ROS for a short duration of time inducing Redox ticking also triggers the pro-survival pathways inside the cell. Nrf2 is the redox sensitive prosurvival transcription factor which acts as master regulator of redox equilibrium. Nrf2 and its dependent genes including HO-1, GCLC, NQO1 etc. are involved in maintaining the cellular redox homeostasis. Role of Nrf2 as dual edges sword has been highlighted in past decade. The cross talk between the Nrf2 and NF-κB is at the focal point of building the redox response network. The present chapter is aimed at providing the insight on the role of Nrf2 and NF-κB as redox sensitive transcription factors in regulating cellular redox status. Further, the chapter brings in light the therapeutic potential of targeting Nrf2 under multiple clinical settings.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of antioxidants and antioxidant enzymes and their role in the mechanisms of signaling and cellular tolerance under stress in plant systems. Major reactive oxygen species (ROS)-scavenging/modulating enzymes include the superoxide dismutase (SOD) that dismutates O2 into H2O2, which is followed by the coordinated action of a set of enzymes including catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX) and peroxiredoxins (Prx) that remove H2O2. In addition to the ROS scavenging enzymes, a number of other enzymes are found in various subcellular compartments, which are involved in maintaining such redox homeostasis either by directly scavenging particular ROS and ROS-byproducts or by replenishing antioxidants. In that respect, these enzymes can be also considered antioxidants. Such enzymes include monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR), glutathione reductase (GR), alternative oxidases (AOXs), peroxidases (PODs) and glutathione S-transferases (GSTs). Some non-enzymatic antioxidants, such as ascorbic acid (vitamin C), carotenes (provitamin A), tocopherols (vitamin E), and glutathione (GSH), work in concert with antioxidant enzymes to sustain an intracellular steady-state level of ROS that promotes plant growth, development, cell cycles and hormone signaling, and reinforces the responses to abiotic and biotic environmental stressors. Offering a unique compilation of information on antioxidants and antioxidant enzymes, this is a valuable resource for advanced students and researchers working on plant biochemistry, physiology, biotechnology, and signaling in cell organelles, and those specializing in plant enzyme technology.

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.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This literature review posits that the transcription factor Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is an attractive candidate therapeutic target in the setting of acute myocardial infarction (AMI). This transcription factor binds to antioxidant response elements (ARE) in the promoter region of a battery of genes that collectively encode an array of antioxidant, phase II drug metabolism, metabolically stabilizing, and overall cytoprotective enzymes, facilitating their transcription at basal levels and increasing transcription in response to various cellular stressors. Following a brief background tutorial on normal cardiac myocyte cellular physiology, key events that occur early in ischemia and reperfusion are outlined and integrated. These include ionic and metabolic dysregulation, electron transport chain uncoupling, mitochondrial depolarization, and the generation of reactive oxygen species (ROS). Abrupt changes in response to ischemia prime opening of the mitochondrial permeability transition pore (MPTP) and cardiac myocytes to generate a burst of ROS upon reperfusion–two key events that contribute to the umbrella term ischemia-reperfusion injury (IRI). How ROS damage cells is then outlined, and through a ROS-centric viewpoint, a case will be made as to how exogenous upregulation of Nrf2 could protect and/or salvage at-risk tissue immediately subjected to infarction and neighboring tissue in the peri-infarct zone (PIZ). The history of how Nrf2 came to be known as the "master regulator of oxidative stress" is reviewed, as well as the discovery of the canonical mechanism of Nrf2 regulation via Kelch-like ECH-associated protein 1 (Keap1) and other alternative mechanisms of endogenous Nrf2 regulation. Finally, compiling interdisciplinary evidence from research publications around the world, the benefits of therapeutically targeting Nrf2 are considered given the timescale and context of acute MI. Drug delivery methods, potential challenges, and limitations are then considered. Cardiac tissue is a dynamic substrate that exhibits changes for up to 90 days after AMI and patient outcomes are directly related to the extent of tissue lost following infarction/reperfusion. Targeting Nrf2 addresses an unmet need, as current clinical therapies focus on precluding occlusions and prompt reperfusion of infarcted tissue, but do not explicitly target at-risk tissue following infarcts and/or present-day reperfusion methodologies.

Available in PDF, EPUB and Kindle. Book excerpt: The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.
