Book Description
The chapters in this volume are the Proceedings of the Satellite Symposium of the XVIth World Congress of the International Society for Heart Research on `Signal Transduction in Normal and Diseased Myocardium' which was held in Rotterdam at the Faculty of Medicine & Health Sciences of the Erasmus University, June 30 and July 1, 1995. Diverse and distinct auto-, para-, and endocrine stimuli arriving at the surface of endothelium, smooth muscle cells, cardiomyocytes and fibroblasts within the myocardium, engage cell type-specific receptors, which lead to transmission of signals across the cell plasma membrane and result in the production and activation of second messengers. The most common mechanism by which these second messengers function is via direct or indirect activation of specific protein kinases. The current challenge for scientists is to identify the specific substrates (e.g. metabolic enzymes, Ca2+-regulating proteins, transcription and mitotic factors) for the many protein kinases, to elucidate the biological significance of the cell type-specific expression heterogeneity of signalling proteins (e.g. membrane receptors, isoenzymes of protein kinase C, G-proteins) and to unravel the cross-talk interaction between the signalling systems (e.g. phospholipase C with adenylate cyclase and phospholipase C with phospholipase D). The multiplicity of receptor types, G-proteins, effector proteins, second messengers and protein kinases, their substrate proteins and the `cross-talk' interactions in the myocardium raises fundamental questions about the mechanisms that ensure the precision and timing of the myocardial responses to hormonal and pharmacological stimuli. This book provides an up-to-date source of information for all scientists and clinicians interested in the mechanisms by which external signals are transmitted to the interior and regulation of a variety of physiological, pathological and pharmacological responses.

Book Description
Signal transduction pathways are at the core of most biological processes and are critical regulators of heart physiology and pathophysiology. The heart is both a transmitter and dynamic receptor of a variety of intracellular and extracellular stimuli, playing a critical role of an integrator of diverse signaling mechanisms. Alterations in signaling pathways are contributing factors in the development and progression of a broad spectrum of diseases, ranging from dysrhythmias and atherosclerosis to hypertension and the metabolic syndrome. Targeting specific components of these signaling pathways has been shown to be effective in preclinical studies with significant therapeutic impact. This book brings together current knowledge in cardiovascular cell signal transduction mechanisms, advances in novel therapeutic approaches to improve cardiac function, and discussion of future directions. Presented from a post-genomic perspective, this exciting book introduces important new ideas in cardiovascular systems biology. It is an invaluable reference for cardiology researchers and practitioners.

Book Description
Cellular signaling in cardiac muscle refers to the myriad of stimuli and responses that direct and control the physiological operation of this organ. Our understand ing of these complex signaling cascades has increased dramatically over the past few decades with the advent of molecular tools for their dissection. Moreover, this infor mation is beginning to provide tangible targets towards manipulating cardiac func tion in the setting of cardiovascular disease. The mechanisms and factors that regulate cardiac cell growth are of particular interest as both adaptive and maladaptive responses can occur during cardiac hypertrophy. Cardiac hypertrophy describes the increase in individual cardiac myocyte size that is accomplished through the series and/or parallel addition of sarcomeres. The ability of cardiac muscle to increase in size through hyperplasia becomes highly restricted or negligible shortly after birth. Consequently, the increase in heart size associated with development and growth of an individual occurs through hypertrophy. In response to a chronic increase in workload, cardiac muscle cells can dramatically increase in size to face their increasing contractile demands. While this plasticity is clearly a ben eficial response under many conditions, it can be highly deleterious and inappropri ate under others. For example, cardiac hypertrophy associated with endurance exercise clearly enhances athletic performance. In contrast, the hypertrophy associated with chronic hypertension, stenotic or regurgitant heart valves, or following a myocardial infarction often continues far beyond the period where this adaptive response is ben eficial.

Book Description
Despite the considerable success in treating diseases of the heart and blood vessels, they still remain the major cause of mortality throughout the world. One of the reasons underlying this problem is our lack of understanding of the molecular and cellular aspects of the processes involved. These problems are fully discussed in Cellular Interactions in Cardiac Pathophysiology, which draws together 25 contributions from leading investigators from all parts of the world. The contributions are grouped under three headings: Extracellular matrix and cardiocyte interaction; Myocytic adaptations and myocardial injury; and Signal transduction.

Book Description
This book presents a multidisciplinary approach to cardiac mechanotransduction. The chapters depict the many faces of the topic, from membrane and ion channel level to mechanics, biochemical signaling and regulation via hormone systems. Cardiac Mechanotransduction is of interest to basic life sciences, like physiology, biochemistry and pharmacology, but also to clinicians working with heart-related problems, such as cardiologists and internists.

Book Description
Cardiac cell biology has come of age. Recognition of activated or modified signaling molecules by specific antibodies, new selective inhibitors, and fluorescent fusion tags are but a few of the tools used to dissect signaling pathways and cross-talk mechanisms that may eventually allow rational drug design. Understanding the regulation of cardiac hypertrophy in all its complexity remains a fundamental goal of cardiac research. Since the advancement of adenovirally mediated gene transfer, transfection efficiency is no longer a limiting factor in the study of cardiomyocytes. A limiting factor in considering cell transplantion as a strategy to repair the damaged heart is cell availability at the right time. Cardiac gap junctions, intercellular communication channels that allow electrical and metabolic coupling and play an important role in arrhythmogenesis are now understood to be exquisite sensors of cardiac change. The reports in this volume incLude elegant studies that made use of cutting edge technological advances and many specialized reagents to address these issues.

Book Description
In many transduction processes, an increasing number of enzymes and other molecules become engaged in the events that proceed from the initial stimulus. In such cases the chain of steps is referred to as a "signalling cascade" or a "second messenger pathway" and often results in a small stimulus eliciting a large response. Hormones and other signalling molecules may exit the sending cell by exocytosis or other means of membrane transport. The sending cell is typically of a specialised type. Its recipients may be of one type or several, as in the case of insulin, which triggers diverse and systemic effects. This book sheds new light in this exciting field of cell transportation research.
