This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past years, the thrust of research in cardiology has been toward an understanding of the engineering of the heart as a pump that transports blood to the various organs of the body. More recently, the fields of biochemistry and biophysics have come to influence heart research. The modern cardiologist can no longer pretend to understand, for example, what is happening to the patient with myocardial infarction or ischemia without understanding the principles of molecular biology. The structure and function of the heart are therefore central themes of cardiological research and practice, which incorporate knowledge and discoveries from diverse disciplines. The importance of lipid metabolism in the myocardium has become clearly understood. In the well-oxygenated heart, fatty acids are the preferred substrates. The fact that the heart derives most of its energy from the oxidation of lipids, which represent the larg est energy store of the body, is logical for an organ that must work throughout our lifetime. There are, however, several lines of evidence that during ischemia, lipids may. be harmful to the heart. High levels of free fatty acids in the serum have been suggested to play a role in causing life-threatening arryhthmias and damage in the ischemic heart. The molecular basis for these effects remains poorly understood, and several possible mechanisms for these harm ful effects have been suggested.

Download or read book Mitochondrial Metabolism in Cardiac Ischemia-Reperfusion Injury written by Jimmy Zhang and published by . This book was released on 2018 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ischemia-reperfusion (IR) injury is the underlying pathology of acute myocardial infarction. The severity of IR injury is driven by mitochondrial metabolism and modulated by mitochondrial quality control mechanisms. The Krebs' cycle metabolite succinate is central to IR injury. Succinate accumulates during ischemia and its oxidation at reperfusion drives injury. The mechanism of ischemic succinate accumulation is controversial, and is proposed to involve reversal of mitochondrial complex-II. Here, using stable isotope resolved metabolomics, we demonstrated that complex-II reversal was possible in hypoxic mitochondria, but was not the primary source of succinate in hypoxic cardiomyocytes or ischemic hearts. Rather, in these intact systems succinate primarily originated from canonical Krebs' cycle activity, partly supported by aminotransferase anaplerosis and glycolysis from glycogen. Augmentation of canonical Krebs' cycle activity with dimethyl-?-ketoglutarate both increased ischemic succinate accumulation and drove substrate-level phosphorylation by succinyl-CoA synthetase, improving ischemic energetics. Although ? of ischemic succinate accumulation was extracellular, the remaining ? was metabolized during early reperfusion, wherein acute complex-II inhibition was protective. These results highlight a bifunctional role for succinate: its complex-II independent accumulation being beneficial in ischemia, and its complex-II dependent oxidation being detrimental at reperfusion. IR injury is also modulated by mitochondrial quality control mechanisms, such as autophagy. Mild mitochondrial uncoupling induces mitochondrial autophagy and both have separately been shown to protect against cardiac IR injury. However, a link between mild uncoupling and autophagy within the context of cardiac IR injury or cardioprotection has not been explored experimentally or therapeutically. Previously, we identified cloxyquin via phenotypic screening as a cardioprotective compound. Here, we demonstrated that cloxyquin mildly uncoupled mitochondria and induced autophagy. Cloxyquin-induced cardioprotection was blocked by the autophagy inhibitor chloroquine. Finally, we showed that cloxyquin-induced cardioprotection translated to an in vivo model of cardiac IR injury. Overall, these data suggest that enhanced insights into the molecular events that take place at mitochondria during ischemia may be exploited for therapeutic benefit in cardiac IR injury.

Download or read book Cardiac Energy Metabolism in Health and Disease written by Gary D. Lopaschuk and published by Springer. This book was released on 2014-08-22 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: The heart has a very high energy demand but very little energy reserves. In order to sustain contractile function, the heart has to continually produce a large amount of ATP. The heart utilizes free fatty acids mainly and carbohydrates to some extent as substrates for making energy and any change in this energy supply can seriously compromise cardiac function. It has emerged that alterations in cardiac energy metabolism are a major contributor to the development of a number of different forms of heart disease. It is also now known that optimizing energy metabolism in the heart is a viable and important approach to treating various forms of heart disease. Cardiac Energy Metabolism in Health and Disease describes the research advances that have been made in understanding what controls cardiac energy metabolism at molecular, transcriptional and physiological levels. It also describes how alterations in energy metabolism contribute to the development of heart dysfunction and how optimization of energy metabolism can be used to treat heart disease. The topics covered include a discussion of the effects of myocardial ischemia, diabetes, obesity, hypertrophy, heart failure, and genetic disorders of mitochondrial oxidative metabolism on cardiac energetics. The treatment of heart disease by optimizing energy metabolism is also discussed, which includes increasing overall energy production as well as increasing the efficiency of energy production and switching energy substrate preference of the heart. This book will be a valuable source of information to graduate students, postdoctoral fellows, and investigators in the field of experimental cardiology as well as biochemists, physiologists, pharmacologists, cardiologists, cardiovascular surgeons and other health professionals.

Available in PDF, EPUB and Kindle. Book excerpt: Mitochondria have been pivotal in the development of some of the most important ideas in modern biology. Since the discovery that the organelle has its own DNA and specific mutations were found in association with neuromuscular and cardiovascular diseases and with aging, an extraordi-nary number of publications have followed, and the term mitochondrial medicine was coined. Furthermore, our understanding of the multiple roles that mitochondria play in cardiac cell homeostasis opened the door for intensive experimentation to understand the pathogenesis and to find new treatments for cardiovascular diseases. Besides its role in adenosine triphosphate generation, mitochondria regu-late a complex network of cellular interactions, involving (1) generation and detoxification of reactive oxygen species, including superoxide anion, hy-drogen peroxide, and hydroxyl radical; (2) maintenance of the antioxidant glutathione in a reduced state and adequate level of mitochondrial matrix superoxide dismutase; (3) cytoplasmic calcium homeostasis, particularly under conditions of cellular calcium loading; (4) transport of metabolites between cytoplasm and matrix; (5) both programmed (apoptosis) and necrotic cell death; and (6) cell growth and development. It is therefore not surprising that this organelle has come to be the center stage in many current investigations of cardiovascular diseases, aging, and agi- related disease. Concomitant with these advances, an impressive effort is under- way for the development of new tools and methodologies to study mitochondrial structure and function, including powerful ways to visualize, monitor, and alter the organelle function to assess the genetic consequences of these perturbations.

This book was released on 2012-12-06 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: During recent decades, bewildering progress has occurred in the field of Molecular and Cellular Biochemistry. Progress has been extraordinarily rapid primarily because of the challenge for finding solutions to a wide variety of diseases and the availability of new techniques for monitoring biochemical processes. This has resulted in a voluminous and complex literature in the field of biochemical medicine so that there is a clear need for the synthesis and analysis of the continuing expansion of valuable data. It was thus considered appropriate to initiate a new series of monographs, each dedicated to a specialized area of investigation, encompassing molecular and cellular processes in health and disease. Most of the biochemical scientists have devoted their energies in understanding the fundamentals of biochemistry and indeed impressive advances have been made in the past. However, the full potential for explanation has been hampered by the concept of universality of biochemical reactions occurring in the cell. In view of the fact that each organ in the body performs a distinct function, it is now beginning to be realized that each cell type is unique in its need to survive and perform its specific function. Accordingly, the aspect of individualty is receiving increased attention for revealing new avenues in the study of pathophysiology of cellular abnormalities.

This book was released on 2013-03-14 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific progress with respect to the important role of various lipids in myocardial function and the dearrangements of lipid metabolism underlying ischaemic heart disease(s) has been con siderable in recent years. In 1986 alone, an overall number ofl 044 full papers covering the topics "Lipids-Heart-Heart Disease", have been published in a variety of biochemistry, physiology, pharmacology and cardiology journals (source: Index Medicus). They have broadened our in sight into the molecular basis of myocardial lipidology and the lipido-chemical basis of car diology in health and disease, and have narrowed the gap between promising pharmacological intervention in experimental animals and clinical treatment of patients suffering from an ischaemic heart. Furthermore, they illustrate the fundamental significance of the product of the union between basic and clinical science. The rapid development of knowledge in the "Lipids-Heart-Heart Disease" triad prompted us to organize the International Symposium on Lipid Metabolism in the Normoxic and lschaemic Heart, held in Rotterdam (The Netherlands) on September 22 and 23, 1986. This meeting was a coproject of the Department of Biochemistry I (Medical Faculty, Erasmus University Rotter dam) and the Department of Physiology (Medical Faculty, University of Limburg) and was held under the auspices of the GerritJan Mulder Foundation (named after a famous Rotterdam physi cian and chemist who lived from 1802-1880) whom we thank for their co-operation. The present volume is a compendium of invited papers and contributions selected from the posters presented during the symposium.

This book was released on 2012-11-19 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades, due to dramatic advances in molecular and cell biology, biochemistry, and genetics, our view on mitochondria as a relatively static cellular powerhouse has changed radically. We now know that these organelles play a critical role in the normal and in the damaged heart. Written by Dr. José Marín-García, Director of the Molecular Cardiology and Neuromuscular Institute, Mitochondria and Their Role in Cardiovascular Disease brings readers up- to-date on the many significant advances in the field of mitochondrial cardiovascular medicine. The book begins with a general introduction to mitochondria, followed by laboratory methods to study the structure and function of the organelle, regulation of replication and biogenesis, and the mechanisms and functional consequences of mitophagia and mitochondrial dynamics. Subsequent chapters deal with mitochondrial oxidative stress and the role that the organelle plays in cell signaling and cell death. Discussions will be undertaken on the biochemistry of mitochondrial cell signaling, including the nature of the proteins engaged in these processes, many of them only recently discovered. Later chapters examine the role of mitochondria and mitochondrial abnormalities in cardiovascular diseases, including their diagnosis, therapeutic options currently available, animal models of mitochondrial disease, and new frontiers in mitochondria cardiovascular medicine, including areas of research that are relatively new or developing, such as proteomics, next generation sequencing, and systems biology.
