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.

Since the publication of my previous monograph in 1974, important progress has been made in the broad area of calcium research, partic ularly as it pertains to secretory phenomena. The significant advance in methodology, while widening the scope of our knowledge, has caused research in this particular area to become more and more specialized. It has, therefore, become increasingly difficult for researchers to consider and evaluate work outside their own areas of specialization and to com prehend the field from a broad perspective. While many valuable re views on the importance of calcium in cellular function are being pro duced, they have not attempted to pull together all of the existing knowledge into a more general narrative. This volume brings together experimental data and theories from diverse sources, and attempts to synthesize into a broad conceptual framework the massive amount of specialized information that presently exists in the general area of cal cium metabolism and the secretory process. It is impossible in a book of this length to discuss specific references in detail and still maintain readability, so generalizations must be made.

Did you know that one single enzyme impacts your odds of contracting most deadly diseases and health conditions? An enormous body of reputable research into this enzyme has been isolated, ignored, and misunderstood by medical experts. The importance of this enzyme simply cannot be overstated. The Calcium Connection: The Little-Known Enzyme at the Root of Your Cellular Health delivers a clear explanation of this enzyme’s function and outlines the steps you can take to gain optimal enzyme health. The accessible, information-packed format teaches you all about Calcium ATPase: how it works, what happens when it goes awry, and easy, practical methods to bring it back into balance and protect it—and your overall health. Whether you’re a health enthusiast, environmentalist, parent, or just want to be better informed, this book will help you boost your health now and into the future. Brunde Broady recounts her tireless quest to find a cure for her son Knute’s compromised health since being whisked away and kept in ICU after birth. The medical establishment could only help manage his condition, but not diagnose or cure him. Doing her own research and documenting everything Knute ate and his reactions to certain foods, she came across two ubiquitous food additives. Diving deeper, she learned how Calcium ATPase, a fundamental regulator of intercellular calcium, is negatively impacted, not only by these additives, but by a torrent of other inhibitors. Knute’s health is a testament to Brunde’s discoveries, and The Calcium Connection gives readers a front-row seat to understanding how to maintain optimized cellular health.

Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the molecular identification of store-operated calcium channels which were reviewed by earlier volumes in the Methods in Signal Transduction series. Crystallographic and pharmacological approaches to the study of calcium channels of epithelial cells are also discussed. Calcium ion is a messenger in most cell types. Whereas voltage gated calcium channels have been studied extensively, the non-voltage gated calcium entry channel genes have only been identified relatively recently. The book will fill this important niche.

The definitive text on the key component for cell functions—intracellular calcium This comprehensive book reveals the evidence for intracellular calcium as a universal switch in all animal, plant, fungal and microbial cells. It shows how the components required for calcium signaling are named and classified; covers the technology that has been developed to study intracellular calcium; describes how calcium is regulated inside cells and how it works to trigger an event; explains the role of intracellular calcium in disease, cell injury, and cell death; reveals how many drugs work through the calcium signaling system; and demonstrates how intracellular calcium is involved in the action of many natural toxins. The book also illustrates how the intracellular calcium signaling system has evolved over millions of years, showing why it was crucial to the origin of life. Additionally, the book promotes the importance of the molecular variation upon which the intracellular calcium signalling system depends. Featuring more than 100 figures (including detailed chemical structures as well as pictures of key pioneers in the field), a bibliography of some 1000 references, and a detailed subject index, this definitive work provides a unique source of scholarship for teachers and researchers in the biomedical sciences and beyond. Emphasizes two key scientific principles—the first to show how intracellular Ca2+ acts as a switch, to activate a wide range of cellular events, and the second demonstrating how an analogue mechanism can be superimposed on such a process Written by an internationally recognized expert in the field Filled with images and references to facilitate learning Fundamentals of Intracellular Calcium is an all-important text for post-graduate students and researchers working in biomedicine and biochemistry. It is also essential for undergraduate lecturers and their students in physiology, medicine, pharmacy, and the biosciences.

The crucial role played by calcium as a cellular messenger has become increasingly evident, as has the recognition that cells spend much energy in maintaining the cytosolic concentration of this cation both constant and low. It is thought they do this to avoid precipitating phosphate, needed as a source of bond energy and to modulate protein structure. Moreover, since calcium that does enter the cell must be disposed with, processes that utilize calcium have evolved, e.g. secretion, contraction, signaling, to name just some. New knowledge concerning the processes of cellular calcium entry, extrusion and the fate of intracellular calcium has accumulated in recent years. Much has also been learned about calcium transport by and across epithelial cells. It seems logical to think that the processes of calcium entry, extrusion and intracellular handling are similar in all cells. We have therefore assembled in one volume overviews and research reports of transport and cellular calcium regulation so as to explore similarities and differences between cells that utilize calcium for metabolic purposes and those whose primary function is transport.
