This collection of presentations from the Ciba Foundation Symposium of 1985 deals with the central role of calcium in intracellular processes. Discusses control of intracellular calcium as well as control by intracellular calcium, covering such topics as muscle contraction, metabolic processes, hormone and transmitter secretion, membrane transport and permeability, cellular architecture and growth, and the possible contribution of calcium gradients to early embryonic development. Includes carefully edited and extensive (almost half the book) discussions of chapter topics between active workers in the field at the end of each chapter.
This volume is based in part upon the proceedings of the Calcium Theme held during the 67th Annual Meeting of the Federation of American Societies for Experimental Biology, which took place in Chicago, AprillO-lS, 1983. The American Society for Pharmacology and Experimental Therapeutics had the primary responsibility for organizing the scientific program with the assistance of other member societies, including the American Physiology Society, American Association of Pathologists, and American Institute of Nutrition. The purpose of the Calcium Theme was to review progress in the diverse areas of investigation bearing on the ubiquitous role of calcium in biological systems. In addition to cont...
This book reports the text of the lectures of the 6th International Conference on Sodium Calcium Exchange held in Lacco Ameno in the Island of Ischia in the Gulf of Naples, Italy, from October 1 to October 5, 2011. The present book uncovers the most striking new findings on NCX that emerged since the previous Conference on Sodium Calcium Exchange, such as the structural dissection of the molecular determinants of Ca2+ sensitivity of the exchanger, the epigenetic regulation of ncx1 gene, the molecular identification of the mitochondrial Sodium Calcium Exchanger, and the discovery of NCX in unexpected anatomical locations such as the female reproductive tract. The book is organized into 11 parts covering NCX structural aspects, genetic and epigenetic regulation, regulatory mechanisms, subcellular localization in mitochondria, involvement in neurodegenerative diseases and in immune regulation, and the role of the cardiovascular and endocrine systems, as well as diabetes in physiology and pathophysiology. Selected chapters of the book are also devoted to the interaction of NCKX and other ion channels and transporters with NCX, like ASICs, TRPM, and NHE.
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.
Upon ligand binding, cell-surface receptors transmit activity signals into the cell, activating multiple metabolic and mitogenic pathways. Although the nature of the stimulatory molecules is infinitely varied, the principles involved in propagating the signals are ubiquitous. Thus, such different stimulators as antigens, cytokines, hormones, and growth factors use similar transduction principles, including ligand-induced receptor internalisation of receptor-ligand complexes, activation of G proteins, aligomerisation, increases in Ca2+ uptake, activation of tyrosine kinases or other kinases and phosphatases, protein phosphorylation or dephosphorylation, and the triggering of oncogenes and transcription factors. The signalling molecules interact with each other through universal zippers, such as SH2 and SH3 domains. This volume integrates the work of the most significant contributors to the field in elucidating the mechanisms involved in these signal transduction pathways.
Biophotonics, Tryptophan and Disease is a comprehensive resource on the key role of tryptophan in wide range of diseases as seen by using optics techniques. It explores the use of fluorescence spectroscopy, Raman, imaging techniques and time-resolved spectroscopy in normal and diseased tissues and shows the reader how light techniques (i.e. spectroscopy and imaging) can be used to detect, distinguish and evaluate diseases. Diseases covered include cancer, neurodegenerative diseases and other age-related diseases. Biophotonics, Tryptophan and Disease offers a clear presentation of techniques and integrates material from different disciplines into one resource. It is a valuable reference for students and interdisciplinary researchers working on the interface between biochemistry and molecular biology, translational medicine, and biophotonics. - Shows the key role of tryptophan in diseases - Emphasizes how optical techniques can be potent means of assessing many diseases - Points to new ways of understanding autism, aging, depression, cancer and neurodegenerative diseases
