Methods in Toxicology, Volume 2: Mitochondrial Dysfunction provides a source of methods, techniques, and experimental approaches for studying the role of abnormal mitochondrial function in cell injury. The book discusses the methods for the preparation and basic functional assessment of mitochondria from liver, kidney, muscle, and brain; the methods for assessing mitochondrial dysfunction in vivo and in intact organs; and the structural aspects of mitochondrial dysfunction are addressed. The text also describes chemical detoxification and metabolism as well as specific metabolic reactions that are especially important targets or indicators of damage. The methods for measurement of alterations in fatty acid and phospholipid metabolism and for the analysis and manipulation of oxidative injury and antioxidant systems are also considered. The book further tackles additional methods on mitochondrial energetics and transport processes; approaches for assessing impaired function of mitochondria; and genetic and developmental aspects of mitochondrial disease and toxicology. The text also looks into mitochondrial DNA synthesis, covalent binding to mitochondrial DNA, DNA repair, and mitochondrial dysfunction in the context of developing individuals and cellular differentiation. Microbiologists, toxicologists, biochemists, and molecular pharmacologists will find the book invaluable.
Current Topics in Bioenergetics, Volume 15: Structure, Biogenesis, and Assembly of Energy Transducing Enzyme Systems presents the reaction mechanisms involved in membrane-associated energy transducing processes at the molecular level. This book discusses the developments in the energy transducing systems. Organized into 11 chapters, this volume begins with an overview of the composition and structural aspects of the four respiratory chain complexes. This text then discusses the genetic aspects of various energy transducing systems. Other chapters consider the electron transfer chains of chloroplast, mitochondria, and some photosynthetic bacteria, which contain a multiprotein complex with similar functional and structural properties. This book discusses as well the structure and function of multiple and variable amounts of subunits in cytochrome-c oxidase from various organisms. The final chapter deals with the interdisciplinary path of bioenergetics, with the center of gravity moving from chemistry through genetics to physics. This book is a valuable resource for biologists.
This volume is based on the proceedings of an International Symposium on "Cytochrome Systems: Molecular Biology and Bioenergetics" that was held at Selva di Fasano near Bari, Italy, between April 7 and 11,1987. It contains papers covering the subjects discussed at the Symposium, contributed both by participants of the meeting and by some invited speakers who were not able to attend. The aim of the Symposium was to bring together experts in various rese arch strategies currently being applied to the study of cytochrome systems, including molecular genetics, protein chemistry, enzymology of electron transfer and protonmotive activity in energy-transducing biological mem branes. Because of the high degree of complexity of cytochrome systems and the increasing sophistication in recent years of the different experimen tal approaches, there has been a growing specialization - sometimes even a tendency to "over-specialization" - among scientists working in this field. This in itself seemed to justify a meeting where representatives of various disciplines could exchange their results and discuss their conclusions. In addition, and perhaps even more importantly, it was felt that meetings of this kind provide an opportunity for a "cross-fertilization" of approaches and ideas among representatives of various fields of science. The present meeting proved to be an ample illustration of the success of such an inter action.
In recent years, the ATP synthase (H+·ATPase, FoFrATPase) has been the subject of intensive IDvestigations in many laboratories. The major reason for this lies in the fact that this enzyme complex catalyses one of the most important reactions in living cells, namely the synthesis of ATP utilizing the energy from an electrochemical transmembrane H+ gradient, generated by the cellular respiratory chain or by the light reactions of photosynthetic organisms. The mechanism by which the H+ motive force is utilized to drive the synthesis of ATP is one of the major unsolved problems in biochemistry. Thus, the fundamental information concerning the-molecular structure and the mechanism of assembly of the ATP synthase is of major significance in cell biology. A seminar/workshop on the Molecular Structure, Function and Assembly of the ATP synthases was held in April, 1987 at the East·West Center, University of Hawaii, Honolulu, Hawaii, to promote exchange of information between laboratories actively engaged in the study of the A TP synthases, and to provide a forum for discussion and coordination of data derived from molecular, genetic and biochemical approaches used in different laboratories. This volume summarizes the result of the seminar/workshop, in the form of a collection of papers presented at the meeting, and provides an overvIew of current work in this rapidly progressing area of research.
International Review of Cytology
Biological functions are almost exclusively attributed to macromolecules, i.e. nucleic acids, proteins and polysaccharides. To gain their complete functional activities these biomolecules have to associate with the nuclear matrix, the cytoskeleton and the cell/plasma membranes. It is the aim of this series to discuss actual aspects in the field of structure-associated genetic and epigenetic functional processes. This series of survey reviews fills the gap in structure-associated information flow, and is a vital reference work for scientists in molecular and cell biology.
Providing both historical background and recent advances, this series reviews in-depth the biologic, molecular, immunologic, and patholic features of this facinating virus family. The current volume focuses on the avian and murine species which have generated novel insights into cancer, and the evolution of the retroviridae.
