Download or read book The Role of Selenium in Health and Disease written by Catherine Méplan and published by MDPI. This book was released on 2020-12-06 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Role of selenium in health and disease”. This book contains ten articles covering recent advances in our understanding of the relationship between the essential micronutrient selenium and human health and disease. Taken together, these articles strengthen the evidence showing that selenium, as a constituent of selenoproteins, is central to biological stress responses and mechanisms commonly altered in most complex disorders. Relevant to public health concerns, this book also emphasizes the U-shaped dose-response relationship between selenium concentration and disease risk across diverse populations from Europe [articles 2,3,6], the Middle East and North Africa [9], and Taiwan [5]. This highlights the importance of personalized nutrition strategies targeted at individuals with increased risk of disease and low selenium intake. The mechanisms by which selenium status, selenoprotein expression, and inherited genetic variations in the selenium pathway interact to affect molecular pathways involved in disease development are explored in human cohorts [2,3,5-7], and in animal [4] and in vitro models [8]. Furthermore, some reports identified novel potential biomarkers of disease risk and prognosis within the selenium pathway that could further our understanding of many chronic diseases [2,3]. Overall, this book broadens our understanding of the role of selenium in chronic diseases, and provides new directions for future preventative approaches.

Download or read book Selenium written by Dolph L. Hatfield and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: As discussed in this book, a large body of evidence indicates that selenium is a cancer chemopreventive agent. Further evidence points to a role of this element in reducing viral expression, in preventing heart disease, and other cardiovascular and muscle disorders, and in delaying the progression of AIDS in HIV infected patients. Selenium may also have a role in mammalian development, in male fertility, in immune function and in slowing the aging process. The mechanism by which selenium exerts its beneficial effects on health may be through selenium-containing proteins. Selenium is incorporated into protein as the amino acid selenocysteine. Selenocysteine utilizes a specific tRNA, a specific elongation factor, a specific set of signals, and the codeword, UGA, for its cotranslational insertion into protein. It is indeed the 21st naturally occurring amino acid to be incorporated into protein and marks the first and only expansion of the genetic code since the code was deciphered in the mid 1960s.

Download or read book Selenium written by Dolph L. Hatfield and published by Springer. This book was released on 2016-09-15 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the current edition, Selenium: Its Molecular Biology and Role in Human Health expands extensively on the previous editions providing readers with the most significant advances in the rapidly developing selenium field. Evidence from epidemiology and veterinary science supports the essential role of selenium in (human) health, but its split personality in both preventing and supporting cancer and also in promoting insulin resistance has become more clearly defined. The pivotal role of glutathione peroxidase 4 in a new process of programmed cell death, ferroptosis, brings new impetus to the field. Recently defined mutations in selenoprotein and biosynthesis factor genes have been identified in patients, and the resulting disorders further emphasize the significance of selenoproteins in human health. The mechanism of selenoprotein biosynthesis, the functions of selenoproteins, and the roles of dietary selenium have been further elucidated, and new regulatory mechanisms involving selenoproteins discovered. The book, therefore, covers the breadth of current selenium research. With up-to-date chapters written by leaders in their fields, it serves as an invaluable resource for novices as well as specialists.

This book was released on 2012-12-06 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selenium plays a fascinating and still poorly understood role in the function of living cells and therefore in human health. Starting with investigations over 60 years ago into its role as a toxic agent in livestock disease, selenium studies have progressed rapidly with the application of tools from immunology and molecular biology. Selenium is now known to be important in human and animal nutrition, has been discovered as a structural component of so-called selenoproteins, and may play a number of physiological roles, ranging from cancer protection to hormone metabolism. Selenium in Biology and Human Health presents research syntheses on a range of topics involving selenium, written by specialists from around the world. It will be of interest to cell biologists and physiologists, nutritional scientists, and animal health researchers.

Download or read book Mammalian Heme Peroxidases written by Clare Hawkins and published by CRC Press. This book was released on 2021-10-07 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mammalian heme peroxidase enzymes play a critical role in innate immune responses and disease prevention. The formation of potent chemical oxidants is essential to this protective physiologic activity in immunity. Although highly beneficial in the context of immune defense, it is now well established that peroxidases and their overproduction of oxidants contribute to the initiation and persistence of many chronic inflammatory conditions in the cardiovascular, neurologic, respiratory, renal, and gastrointestinal systems. Peroxidasins, a protein family related to heme peroxidases, play a novel role in tissue biogenesis and matrix assembly, which are also attracting attention in different pathological contexts. Given the diverse roles of mammalian heme peroxidases and the breadth and incidence of pathologies associated with these enzymes, there has been significant interest in modulating peroxidase activity as a therapeutic strategy. This book highlights recent developments in our understanding of the chemistry, biochemistry and biological roles of mammalian peroxidases and their associated oxidants, their involvement in both innate immunity and chronic inflammatory disease in a variety of end organs, and potential therapeutic approaches to modulate and prevent damaging reactions. Key Features Structure and biosynthesis of mammalian peroxidases Reactivity of hypohalous acids with biological substrates Peroxidases in innate immunity Peroxidases in human pathology Modulation of peroxidase-induced biological damage

Download or read book Redox Regulation of Differentiation and De differentiation written by Carsten Berndt and published by CRC Press. This book was released on 2021-08-26 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell differentiation and the development of multicellular organisms are processes of self-assembly, controlled and driven by signaling molecules and cascades including redox regulation. These reactions may have provided the energy for the first metabolic steps in the evolution of life. Today, redox modifications are established as important regulatory events in cellular functions including differentiation and development. Redox modifications of single cysteines regulate differentiation of stem cells, formation of functioning organs, and de-differentiation such as formation of cancer cells. Current cancer therapy is based on redox events as well and regeneration often reactivates developmental pathways. Understanding differentiation and de-differentiation on a molecular level is therefore a prerequisite for the continuing development of new medical therapies. This book summarizes the roles of redox regulation in development by bringing together different concepts and comparing similarities and differences between various cell types and species. An international team of contributors presents several new aspects of redox-regulated differentiation and de-differentiation, including aspects of redox medicine. Key Features Provides the first summary on this important topic Reviews redox-dependent development of model organisms and single organs Highlights the redox-regulated pathways important for differentiation processes Illustrates the potential of redox medicine Combines state-of-the-art knowledge in differentiation/development, aging/longevity, and repair/regeneration Written by leading experts in the field Related Titles Ayyanathan, K., ed.
