The IGF System


Book Description

It has been over 40 years since the original report by Salmon and Daughaday demon strating that the ability of GH to stimulate sulfation of cartilage was mediated by a "sulfation factor. " In the ensuing decades, it has become apparent that this "sulfation factor activity" encompasses a complex system ofligands (IGFs), receptors, and carrier proteins that are, in tum, responsible for a wide array of cellular actions. The IGF system has been demonstrated to be critically involved in both intrauterine and postnatal growth, and to have important implications in cancer biology as well, owing to the ability of the IGFs to function in endocrine, paracrine, and autocrine modes and given the wide distri bution of IGFs in virtually every organ system. The contributions to The /GF System reflect the wide span of interest in the IGF system and its implications for normal and abnormal growth and metabolism. The chapters have been divided into four broad sections: I. Molecular biology of the IGF system; II. Bio logical actions of the IGFs; III. IGF physiology; and IV. Clinical aspects of the IGFs. We have made every effort to highlight the major contemporary themes in IGF biology, but as is inevitable in such a fast-moving field, perspectives will continue to change as new information is accumulated.




Molecular Biology and Physiology of Insulin and Insulin-Like Growth Factors


Book Description

This volume addresses a fundamental puzzle in biology and medicine, namely, how does tissue develop, repair and replace itself. The answer appears to lie in growth factors and their regulation. To thrive and survive we need growth factors and this book concentrates on two factors that are related to growth hormone. Growth hormone does not act directly on all tissues, but mediates many of its actions through the release of insulin-like growth factors from the liver. The growth factors were originally called somatomedins by McConaghey and Sledge (1), who discovered that they mediated growth-like effects of growth hormone. However, the factors were purified on the basis of their insulinomimetic actions on fat and muscle and it is their relationship to the insulin family of pep tides that now gives them their name (2,3) of insulin-like growth factors (IGFs). They mediate the actions of. growth hormone on the proteoglycan synthesis of cartilage and produce mitogenic effects in fibroblast cultures.




Growth Hormone in Adults


Book Description

This revised new edition reviews the substantial advances in our understanding of the vital role of growth hormone (GH) in maintaining adult health, and the resulting disorders from GH deficiency. The first edition, published in 1996, provided a pioneering overview of the subject; this new edition provides an even more comprehensive account, fully updated with the latest research, clinical applications, and references. The therapeutic benefits of GH treatment in GH deficiency are thoroughly evaluated, including effects on metabolism, cardiac function, exercise performance, psychosocial aspects, and aging and gender-specific effects. This compilation by the world's leading experts covers clinical investigation, diagnosis and treatment issues, and encompasses new knowledge of the control and action of GH secretion. This volume is the most authoritative, comprehensive, and detailed account available and will be an essential source of reference for all endocrinologists.

Book Description

This Special Issue of Cells on “Insulin-Like Growth Factors in Development, Cancers and Aging” provides a collection of modern articles dealing with the role of insulin-like growth factors (IGF1) in cancer biology, aging and development. Featured articles explore basic and clinical aspects of the IGF1 system, including post-genomic analyses as well as novel approaches to target the IGF1 receptor (IGF1R) in oncology.




Growth Factors and Their Receptors in Cell Differentiation, Cancer and Cancer Therapy


Book Description

Annotation G.V. Sherbet provides insights into the signalling processes involved in morphogenesis and pathogenesis with emphasis on using the elements of the signalling cascades as targets for therapeutic deployment. The book focuses on the relationships and convergence of growth factors and their receptors in development and pathogenesis.




Insulin-like Growth Factors


Book Description

During the past decade, the continued interest in insulin-related growth factors has been documented by a plethora of research programs and publications focused on these growth factors. Both molecular and cellular biological techniques have improved and enabled investigators to study the properties of the growth factors in depth. This volume covers the molecular (genetic) aspects of the growth factors, their binding proteins and receptors, as well as those factors affecting their gene transcription and translation. In addition, aspects of the cellular action of these growth factors through their receptors and how this impacts normal cellular function are discussed. The book will provide valuable information for researchers in physiology, biology, endocrinology, and metabolism.




Gigantism and Acromegaly


Book Description

Gigantism and Acromegaly brings together pituitary experts, taking readers from bench research, to genetic analysis, clinical analysis, and new therapeutic approaches. This book serves as a reference for growth hormone over-secretion and its diagnosis and treatment for endocrinologists, pediatricians, internists, and neurosurgeons, and for geneticists. Pharmaceutical companies may use it as a reference for drug development and research. Students, residents and fellows in medicine and endocrinology and genetics will also find it valuable as it provides a single up-to-date review of the molecular biology of gigantism and acromegaly as well as recommended approaches to evaluation and management. Acromegaly is a rare pituitary disorder that slowly changes its adult victim’s appearance over time: larger hands and feet, bigger jaw, forehead, nose, and lips. Generally, a benign pituitary tumor is the cause and symptoms of acromegaly can vary from patient to patient, making a diagnosis difficult and prolonging suffering for years. Early detection is key in the management of acromegaly as the pathologic effects of increased growth hormone (GH) production are progressive and can be life-threatening as the result of associated cardiovascular, cerebrovascular, and respiratory disorders and malignancies. Accessible, up-to-date overview of the characteristics, state-of-the-art diagnostic procedures, and management of acromegaly and gigantism Provides a unique compendium of endocrinology, genetics, clinical diagnosis and therapeutics Contains contributions from internationally known experts who have treated patients with acromegaly and gigantism




The Endocrinology of Growth, Development, and Metabolism in Vertebrates


Book Description

The Endocrinology of Growth, Development, and Metabolism in Vertebrates provides an overview of vertebrate endocrinology. This book aims to strengthen the bridge between medical and comparative endocrinologists by addressing the benefits that they can derive from this association. Organized into five parts encompassing 24 chapters, this volume starts with a discussion on the structure and biological function of growth hormone (GH) and prolactin (PRL) family. This book then explains the extrinsic, genetic, and humoral factors that influence animal growth, particularly in poikilotherms. This tex ...




IGFs:Local Repair and Survival Factors Throughout Life Span


Book Description

Insulin-like growth factors (IGFs), their binding proteins and their receptors play important roles in regulating growth, metabolism, proliferation and survival for many cells and tissues throughout lifespan in humans and other species. Circulating IGF1 is known to be an endocrine regulator, with metabolic effects related to, and partly convergent with, insulin signalling. IGF1 also mediates many of the growth promoting effects of GH, and there is an ongoing debate as to the relative contributions of endocrine-, vs locally-derived IGF1 for systemic growth. More recently however, it has become clear that IGFs may be key local growth and cellular survival factors for many different tissues, active from early in embryonic development, essential for normal maturation and growth during foetal life. IGFs continue to play important roles throughout adult life in many diverse processes such as tissue repair, cellular proliferation, tissue remodelling and metabolic regulation. IGF systems are tightly regulated; orderly control of cellular repair and metabolism is central to healthy ageing, whilst uncontrolled proliferation can lead to cancer.
