Zinc Signals in Cellular Functions and Disorders


Book Description

This book describes the crucial role of "zinc signals" in biological processes on a molecular and physiological basis, discussing future directions and questions underlying this unique phenomenon. To accomplish this, a group of worldwide leaders in the field, who have made outstanding contributions, overview zinc signals from a professional standpoint. Zinc plays an indispensable role in various cellular processes. It regulates a great number of protein functions including transcription factors, enzymes, adapters, and growth factors as a structural or catalytic factor or both. Recently, another function of zinc has received extensive interest and attention because of its potential importance as a signaling mediator. Zinc plays a dynamic role as an intracellular and extracellular signaling factor and thus regulates cellular signaling pathways, which enables communication between cells, conversion of extracellular stimuli to intracellular signals, and control of various intracellular events. These functions of zinc have become recognized as “zinc signals,” which play critical roles in physiology, and therefore their imbalance can cause a variety of problems with regard to human health. Because the notion of zinc signals is quite new and no integrative review books focusing on them have yet been published, we believe this book will provide very timely information on the subject and thus should be of importance and interest to a wide range of readers.




Zinc Signaling


Book Description

This book, now in an extensively revised second edition, describes the crucial role of zinc signaling in biological processes on a molecular and physiological basis. Global leaders in the field review the latest knowledge, including the very significant advances in understanding that have been achieved since publication of the first edition. Detailed information is provided on all the essentials of zinc signaling, covering molecular aspects and the roles of zinc transporters, the zinc sensing receptor, and metallothioneins. Detection techniques for zinc signals, involving genetically encoded and chemical probes, are also described. The critical contributions of the zinc signal in maintaining health and the adverse consequences of any imbalance in the signal are then thoroughly addressed. Here, readers will find up-to-date information on the significance of the zinc signal in a wide range of conditions, including cardiovascular disorders, neurodegenerative diseases, diabetes, autoimmune diseases, inflammatory conditions, skin disease, osteoarthritis, and cancer. The book will be of value for researchers, clinicians, and advanced students.

Dietary Reference Intakes for Vitamin A, Vitamin K, Arsenic, Boron, Chromium, Copper, Iodine, Iron, Manganese, Molybdenum, Nickel, Silicon, Vanadium, and Zinc


Book Description

This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.




Zinc Deficiency


Book Description

Zinc is the second most prevalent trace found in the human body after iron. It is essential for normal cell function and metabolism, playing a central role in over 300 enzymatic reactions, and protects cells from free radical damage. The central role of zinc in cell growth and differentiation explains the dramatic effect of zinc deficiency in tissues with a rapid cell turnover such as hair growth. In recent years, much interest has been generated by the possibility that subclinical zinc deficiency may significantly increase the incidence of and morbidity and mortality from diarrhea and upper respiratory tract infections. Clinical manifestations of zinc deficiency include delayed sexual maturation, impotence, hypogonadism, oligospermia, alopecia, dysgeusia, immune dysfunction, night blindness, impaired wound healing, and various skin lesions. After bariatric surgery, zinc deficiency is often associated with other micronutrients deficiencies, mainly iron. Chapter One in this book provides a review of the etiology, health implications and management of zinc deficiency after bariatric surgery. Currently, recommendations regarding routine screening for zinc deficiency or the use of daily oral zinc supplementation in individuals after bariatric surgery are not based on clinical trials. Gaps that exist in the understanding of zinc deficiency are summarized in Chapter Two. Chapter Three brings attention to the important implications of zinc in carcinogenesis. It provides a comprehensive review of the current literature on the role of zinc in carcinogenesis, as well as highlights the significance of zinc homeostasis mechanisms, which are essential for understanding the key roles of this trace element in carcinogenesis.




Protein Kinase CK2 Cellular Function in Normal and Disease States


Book Description

Protein kinase CK2 (formerly casein kinase II or 2) is known to play a critical role in the control of cell growth and cell death and is thus intimately involved in the development of cancer. More specifically, CK2 has been found to be elevated in all cancers examined. While CK2 levels are known to be high in proliferating normal cells, CK2 has also been found to be a potent suppressor of apoptosis and is a link to the cancer cell phenotype, which is characterized by deregulation of both cell proliferation and cell death. Indeed, it would appear that CK2 impacts many of the hallmarks of cancer and it has now gained considerable attention as a potential target for cancer therapy. Protein Kinase CK2 and Cellular Function in Normal and Disease States increases knowledge of the role of CK2 in the development of cellular dysfunction and emphasizes that this protein may serve as a target of drug development for improved cancer therapy. In addition, it is a handy tool that provides cancer researchers, graduate students, and all scientists involved in CK2 research with one main source for the latest advances in CK2 research. ​




Dietary Phytochemicals

Nutrition and Traumatic Brain Injury


Book Description

Traumatic brain injury (TBI) accounts for up to one-third of combat-related injuries in Iraq and Afghanistan, according to some estimates. TBI is also a major problem among civilians, especially those who engage in certain sports. At the request of the Department of Defense, the IOM examined the potential role of nutrition in the treatment of and resilience against TBI.
