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.

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.

Whenever the heart is challenged with an increased work load for a prolonged period, it responds by increasing its muscle mass--a phenomenon known as cardiac hypertrophy. Although cardiac hypertrophy is commonly seen under physiological conditions such as development and exercise, a wide variety of pathological situa tions such as hypertension (pressure overload), valvular defects (volume overload), myocardial infarction (muscle loss), and cardiomyopathy (muscle disease) are also known to result in cardiac hypertrophy. Various hormones such as catecholamines, thyroid hormones, angiotensin II, endothelin, and growth factors have also been shown to induce cardiac hypertrophy. Although the exact mechanisms underlying or pathological forrns of cardiac hypertrophy are poorly under the physiological stood, an increase in the intraventricular pressure is believed to represent the major stimulus for the development of cardiac hypertrophy. In this regard, stretching of the cardiac muscle has been shown to induce the hypertrophic response, but the role of metabolic influences in this process cannot be ruled out. Furthermore, different hormones and other interventions in the absence of stretch have been observed to stimulate protein synthesis in both isolated cardiomyocyte and vascular myocyte preparations. Nonetheless, it is becoming dear that receptor as well as phospholipid linked signal transduction pathways are activated in some specific manner depend ing upon the initial hypertrophic stimulus, and these then result in an increase in the size and mass of cardiomyocytes.

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.

The aim of Molecular Cardiology: Methods and Protocols is to document state-of-the-art molecular and genetic techniques in the area of cardiology. These modern approaches enable researchers to readily study heart diseases at the molecular level and will promote the development of new therapeutic str- egies. Methods for genetic dissection, signal transduction, and microarray analysis are excellent tools for the study of the molecular mechanisms of cardiovascular diseases. Protocols for transgenesis take advantage of recent advances in many areas of molecular and cell biology. Transgenic models of heart diseases (cardiac hypertrophy, cardiac dysfunction, and so on. ) are powerful tools for the study of heart disease pathogenesis. Methods for gene transfer to heart tissue using viral and nonviral vectors form the basis of gene therapy for heart diseases. Heart-specific promoters containing a hypox- inducible cardioprotective gene switch are key for protection of the heart from ischemia. Gene and stem cell therapies open novel and exciting avenues for the prevention and treatment of heart diseases. Molecular Cardiology: Methods and Protocols consists of 26 chapters de- ing with various aspects of molecular cardiology, including gene transfer and gene therapy for cardiovascular disease, stem cell therapy for cardiovascular disease, gene analysis in the injured and hypertrophied heart, and transgenesis in cardiovascular research. This book provides step-by-step methods for the successful completion of experimental procedures, and would be useful for both experienced and new investigators in the field of molecular cardiology.
