This book was released on 2012-12-06 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The special issue of Molecular and Cellular Biochemistry focuses on `Control of Gene Expression by Catecholamines and the Renin-Angiotensin System' in health and disease. In recent years, great progress has been made in the understanding of catecholamine and angiotensin II modulated gene expression. There is also increasing evidence that catecholamine and angiotensin II induced cellular injury not solely arises from classical pathways but also from a perturbed gene expression. Taking into account that catecholamines and angiotensin II are vital for a balanced gene expression of many cells, the intriguing possibility arises that various disease are initiated or aggravated by such an imbalance. Catecholamine and angiotensin II influences can be in excess arising from, for example, hypercaloric food intake or psychosocial stress. During early progression of heart failure, sympathetic activity and angiotensin II influences also become increased. Due to beta-adrenergic receptor downregulation, depressed catecholamine influences are expected in the final stage of heart failure. An imbalanced influence of catecholamines and angiotensin II on gene expression leads to disordered molecular structures of the cell and an impaired cell function. This focused issue is organized into chapters concentrating on catecholamines, angiotensin II, and the interaction between catecholamines and angiotensin II. Basic biochemical processes are covered in detail and the potential of these pathways for explaining chronic diseases associated with excess catecholamine and angiotensin II influences should become apparent. It is hoped that this focussed issue triggers novel research into the development of drugs that are targeted at diseases characterized by an imbalanced gene expression involving catecholamines and angiotensin II.

This book was released on 2020-08-19 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selected Chapters from the Renin-Angiotensin System aims to provide a comprehensive overview of the most important physiological and pathophysiological roles of the renin-angiotensin system (RAS). The complex and convoluted RAS has been investigated for many years and, through rigorous scientific research, many important and previously unknown components and functions of the RAS have come to light. These discoveries have been crucial in the understanding of this system and provide a basis for effective modulation of the system as part of therapeutic strategies for a number of widespread disorders. New studies are continuing to elucidate the RAS and the mechanisms associated with its functions. This book discusses relevant scientific knowledge about the RAS and intends to introduce the reader to cutting-edge research with an accentuation on the mechanisms at the functional/physiological and molecular/cellular levels.

This book was released on 2013-06-29 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific advances over the past two decades have afforded unprecedented oppor tunities to understand the structure and function of receptors, receptor-ligand interactions, and receptor signaling. The extent ofprogress in this area is underscored by the recent Nobel Prize for Medicine and Physiology to Alfred Gilman and Martin Rodbell, both of whose work in understanding receptorlG-protein interactions has redefined the way in which we think of how hormones and neurochemicals exert their activity on cellular function. This book is replete with examples of current research approaches to help us better understand the cellular roles in which the renin-angiotensin system and the angiotensin receptors participate. Clearly, defining the structure of angiotensin receptor subtypes is an important first step in cJarifying the mechanisms by which these receptors take part in cellular function. However, the chapters within this book range far beyond structural studies and encompass research on tissue specific expression of the angiotensin receptor subtypes, the genetic regulation ofthese receptors, and the unique function ofvarious angiotensin subtypes in different organ systems, such as the brain, the reproductive system, adipose tissue, the heart, and the kidneys.

Download or read book The Renin angiotensin System and the Neuroendocrine Regulation of Energy Balance written by Annette D. De Kloet and published by . This book was released on 2011 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: The renin-angiotensin system (RAS) is best-known as an endocrine system that regulates hydromineral balance and cardiovascular function. More recently, it has become evident that the RAS acts in an autocrine or paracrine fashion within many tissues to influence obesity and its comorbidities. The goal of these studies was to test specific hypotheses relating to how angiotensin-II (Ang-II; an end-product of the RAS) influences energy and glucose homeostasis. The overall hypothesis is that Ang-II acts in the brain to promote negative energy balance and peripherally to enhance energy storage. To assess the role of the RAS in energy and glucose homeostasis, body weight and composition, food intake and glucose tolerance were examined in rats given captopril. Captopril is an angiotensin-converting enzyme (ACE) inhibitor that prevents circulating Ang-II from being formed but does not readily access the brain. Rats fed either high-fat or low-fat diet and given captopril weighed less, had less body fat, and had improved glucose tolerance relative to controls. Rats given captopril also ate significantly less than free-fed controls, and comparisons to pair-fed controls indicated that the reduced weight gain and adiposity and improved glucose tolerance were due primarily to decreased food intake. Because systemic captopril elevates plasma and consequently brain angiotensin-I (Ang-I; the precursor for Ang-II and substrate for ACE), but does not itself enter the brain, we further hypothesized that still-active brain ACE would convert the increased Ang-I into Ang-II, and that the increased central Ang-II would contribute to systemic captopril-induced negative energy balance. Consistent with this, the reduction in food intake elicited by peripheral captopril was reversed by co-administration of the ACE inhibitor into the brain. These results suggest that captopril protects against diet-induced obesity, in part by elevating central Ang-II levels. These studies were extended by directly evaluating the role of RAS in the CNS regulation of energy balance. Osmotic minipumps were used to chronically administer Ang-II to rats in order to examine the effect of increased brain Ang-II signaling on energy balance. Chronic elevation of central Ang-II signaling resulted in reduced food intake, body weight gain and adiposity. The decrease in body weight and adiposity occurred relative to free-fed and pair-fed controls, implying that reduced food intake, in and of itself, does not underlie all of these effects. Consistent with this, rats administered Ang-II exhibited increased energy expenditure and enhanced expression of indices of adipose tissue sympathetic activation. Moreover, chronic icv Ang-II increased the anorectic corticotrophin-releasing and thyroid-releasing hormones within the hypothalamus. This hypothalamic gene expression profile coupled with the abundant angiotensin type-1 receptor expression within the paraventricular nucleus of the hypothalamus (PVN) led to the hypothesis that the PVN angiotensin type-1 receptor population may contribute to some of these processes. This hypothesis is discussed in the final chapter. Collectively, the experiments included in this dissertation support the overall hypothesis that Ang-II acts within the CNS to promote negative energy balance, and suggest that some contributing mechanisms include reduced food intake, elevated energy expenditure and enhanced sympathetic activation of adipose tissue.

Download or read book The Protective Arm of the Renin Angiotensin System RAS written by Thomas Unger and published by Academic Press. This book was released on 2015-04-18 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Protective Arm of the Renin Angiotensin System: Functional Aspects and Therapeutic Implications is the first comprehensive publication to signal the protective role of a distinct part of the renin–angiotensin system (RAS), providing readers with early insight into a complex system which will become of major medical importance in the near future. Focusing on recent research, The Protective Arm of the Renin Angiotensin System presents a host of new experimental studies on specific components of the RAS, namely angiotensin AT2 receptors (AT2R), the angiotensin (1–7) peptide with its receptor Mas, and the enzyme ACE 2, which exert significant beneficial, health-promoting actions by counterbalancing the well-known harmful arm of the RAS with its classical angiotensin AT1 receptor. This innovative concept of the protective arm of the RAS, examined in this reference, represents an indispensable background and will be a strong support for biomedical students, researchers, cardiologists, surgeons, nephrologists, diabetologists, and endocrinologists, as well as any other physician or researcher concerned with RAS physiology, pathophysiology and clinical implications. Provides a complete understanding of the protective side of the Renin Angiotensin System (RAS) involving angiotensin AT2 receptor, ACE2, and Ang(1-7)/Mas receptor Combines the knowledge of editors who pioneered research on the protective renin angiotensin system including; Dr. Thomas Unger, one of the founders of AT2 receptor research; Dr. Ulrike M. Steckelings, who contributed significantly to first preclinical studies with a novel specific AT2-agonist, and Dr. Robson Santos who pioneered research on angiotensin-(1-7) and its receptor Mas. Shows that the protective RAS axes are able to ameliorate the course of several cardiovascular, renal, metabolic and neurological diseases Provides the basis for the understanding of a novel therapeutic approach to stimulate components of the protective arm of the RAS.

Download or read book The Endothelium written by Michel Félétou and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Download or read book The Juxtaglomerular Apparatus written by Roland Taugner and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the juxtaglomerular apparatus (JGA) of the kidney and of the synthesis and secretion of renin has increased to such an extent over the past few years that it is now appropriate to summarize this knowledge in a monograph on the JGA, the first of its kind. It was the authors' special concern to demonstrate the association between structure and function for renin secretion, not only within the juxtaglomerular region, but also in the region of the renal cortex beyond the JGA. The description of the pathology of the human JGA, studded with references to experimental findings but nevertheless fully self-contained, should help to make this monograph also useful for clinicians.
