Book Synopsis Mechanisms Underlying the Essential Role of Mitochondria in Chronological Aging of the Yeast Saccharomyces Cerevisiae by : Adam Beach
Download or read book Mechanisms Underlying the Essential Role of Mitochondria in Chronological Aging of the Yeast Saccharomyces Cerevisiae written by Adam Beach and published by . This book was released on 2015 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes studies that have resulted in uncovering molecular and cellular mechanisms underlying the essential role of mitochondria in chronological aging of the baker’s yeast, Saccharomyces cerevisiae. The Titorenko laboratory has recently identified lithocholic acid (LCA), a bile acid and a natural compound that operates synergistically with caloric restriction (CR) to cause a substantial increase in yeast chronological lifespan under longevity-extending CR conditions. As a first step towards establishing a mechanism by which LCA extends longevity of chronologically aging yeast limited in calorie supply, I investigated the distribution of LCA within yeast cells. I found that exogenously added LCA enters yeast cells, is sorted only to mitochondria, resides mainly in the inner mitochondrial membrane and also associates with the outer membrane of mitochondria. I demonstrated that LCA-elicited changes in the membrane lipidome of mitochondria trigger age-related alterations in mitochondrial respiration, membrane potential, reactive oxygen species (ROS) quantity, oxidative macromolecular damage, respiratory complexes composition and ATP concentration. My findings provided evidence that the longevity-extending potential of LCA is due in part to its ability to alter the age-related dynamics of mitochondrially produced ROS in both chronologically ʺyoungʺ and ʺoldʺ cells, thus reducing the damaging effect of these ROS in ʺyoungʺ cells and amplifying their ʺhormeticʺ effect in ʺoldʺ cells. I demonstrated that LCA alters the age-related dynamics of changes in the levels of many mitochondrial proteins, as well as numerous proteins in cellular locations outside of mitochondria. My findings imply that LCA-driven changes in the mitochondrial lipidome alter the mitochondrial proteome and functionality, thereby enabling mitochondria to operate as signaling organelles that orchestrate the establishment of an anti-aging transcriptional program for many longevity-defining nuclear genes. Based on these findings, I proposed a model for how such LCA-driven changes early and late in the life of chronologically aging yeast cause a stepwise development of an anti-aging cellular pattern and its maintenance throughout lifespan. Moreover, I provided evidence that mitophagy, a selective autophagic degradation of aged and dysfunctional mitochondria, is a longevity assurance process that in chronologically aging yeast underlies the synergistic beneficial effects of CR and LCA on lifespan.
Book Synopsis Brain Lipids in Synaptic Function and Neurological Disease by : Jacques Fantini
Download or read book Brain Lipids in Synaptic Function and Neurological Disease written by Jacques Fantini and published by Academic Press. This book was released on 2015-05-12 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lipids are the most abundant organic compounds found in the brain, accounting for up to 50% of its dry weight. The brain lipidome includes several thousands of distinct biochemical structures whose expression may greatly vary according to age, gender, brain region, cell type, as well as subcellular localization. In synaptic membranes, brain lipids specifically interact with neurotransmitter receptors and control their activity. Moreover, brain lipids play a key role in the generation and neurotoxicity of amyloidogenic proteins involved in the pathophysiology of neurological diseases. The aim of this book is to provide for the first time a comprehensive overview of brain lipid structures, and to explain the roles of these lipids in synaptic function, and in neurodegenerative diseases, including Alzheimer’s, Creutzfeldt-Jakob’s and Parkinson’s. To conclude the book, the authors present new ideas that can drive innovative therapeutic strategies based on the knowledge of the role of lipids in brain disorders. Written to provide a "hands-on" approach for readers Biochemical structures explained with molecular models, and molecular mechanisms explained with simple drawings Step-by-step guide to memorize and draw lipid structures Each chapter features a content summary, up-to-date references for additional study, and a key experiment with an explanation of the technique

Download or read book Nitric Oxide written by Louis J. Ignarro and published by Academic Press. This book was released on 2000-09-13 with total page 1023 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitric oxide (NO) is a gas that transmits signals in an organism. Signal transmission by a gas that is produced by one cell and which penetrates through membranes and regulates the function of another cell represents an entirely new principle for signaling in biological systems. NO is a signal molecule of key importance for the cardiovascular system acting as a regulator of blood pressure and as a gatekeeper of blood flow to different organs. NO also exerts a series of other functions, such as acting a signal molecule in the nervous system and as a weapon against infections. NO is present in most living creatures and made by many different types of cells. NO research has led to new treatments for treating heart as well as lung diseases, shock, and impotence. Scientists are currently testing whether NO can be used to stop the growth of cancerous tumors, since the gas can induce programmed cell death, apoptosis. This book is the first comprehensive text on nitric oxide to cover all aspects--basic biology, chemistry, pathobiology, effects on various disease states, and therapeutic implications. Edited by Nobel Laureate Louis J. Ignarro, editor of the Academic Press journal, Nitric Oxide Authored by world experts on nitric oxide Includes an overview of basic principles of biology and chemical biology Covers principles of pathobiology, including the nervous system, cardiovascular function, pulmonary function, and immune defense

Book Synopsis Principles of Bioenergetics by : Vladimir P. Skulachev
Download or read book Principles of Bioenergetics written by Vladimir P. Skulachev and published by Springer Science & Business Media. This book was released on 2012-12-15 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles of Bioenergetics summarizes one of the quickly growing branches of modern biochemistry. Bioenergetics concerns energy transductions occurring in living systems and this book pays special attention to molecular mechanisms of these processes. The main subject of the book is the "energy coupling membrane" which refers to inner membranes of intracellular organelles, for example, mitochondria and chloroplasts. Cellular cytoplasmic membranes where respiratory and photosynthetic energy transducers, as well as ion-transporting ATP-synthases (ATPases) are also part of this membrane. Significant attention is paid to the alternative function of mitochondria as generators of reactive oxygen species (ROS) that mediate programmed death of cells (apoptosis and necrosis) and organisms (phenoptosis). The latter process is considered as a key mechanism of aging which may be suppressed by mitochondria-targeted antioxidants.

Available in PDF, EPUB and Kindle. Book excerpt: Cytochromes c are haemoproteins which carry out electron transfer in a wide variety of biological systems, necessitating different kinds of cytochrome c to fulfill different biological roles. The evolutionary relationship between cytochromes c and their host organisms are described, as well as their structural, spectroscopic and redox properties, including both electron-transfer rates and redox potentials. The treatment is aimed at the non-specialist so that both the techniques described and their application to cytochromes c can be understood. All classes of cytochrome c are dealt with to provide a comprehensive account of the field. No other text provides such a broad survey. Similar to the earlier volume "Cytochromes c: Biological Aspects" which deals with the classification, biosynthesis and biological role of cytochromes c, the present book is aimed at research workers and advanced students.
Book Synopsis Membrane Biogenesis by : Jos A.F. Op den Kamp
Download or read book Membrane Biogenesis written by Jos A.F. Op den Kamp and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many individual aspects of the dynamics and assembly of biological membranes have been studied in great detail. Cell biological approaches, advanced genetics, biophysics and biochemistry have greatly contributed to an increase in our knowledge in this field.lt is obvious however, that the three major membrane constituents - lipids, proteins and carbohydrates- are studied, in most cases separately and that a coherent overview of the various aspects of membrane biogenesis is not readily available. The NATO Advanced Study Institute on "New Perspectives in the Dynamics of Assembly of Biomembranes" intended to provide such an overview: it was set up to teach students and specialists the achievements obtained in the various research areas and to try and integrate the numerous aspects of membrane assembly into a coherent framework. The articles in here reflect this. Statting with detailed contributions on phospholipid structure, dynamics, organization and biogenesis, an up to date overview of the basic, lipidic backbone of biomembranes is given. Extensive progress is made in the research on membrane protein biosynthesis. In particular the post- and co-translational modification processes of proteins, the mechanisms of protein translocation and the sorting mechanisms which are necessary to direct proteins to their final, intra - or extracellular destination have been characterized in detail. Modern genetic approaches were indispensable in this research area: gene cloning, hybrid protein construction, site directed mutagenesis and sequencing techniques elucidated many functional aspects of specific nucleic acid and amino acid sequences.
