This book was released on 2012-12-06 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: An essential element in the development and functional integrity of all organisms is intercellular communication. This is achieved by the secretion of soluble messenger molecules which subsequently interact with receptor-effector pathways in the responsive cells. Hormones are traditionally defined as chemical messengers synthesized by endocrine glands. Unlike hormones produced by endocrine glands, growth factors are hormone-related substances produced by many tissues and play an important role in controlling growth and development. While the exact physiological roles of growth factors have yet to be elucidated, they play important roles in the regulation of cellular proliferation and/or differentiation during ontogenesis, growth and differentiation. During recent years there has been a substantial increase in research related to peptide growth factors, their receptors, and modes of action. With the discovery and characterization of numerous growth factors, it became clear that these growth factors had multiple features in common with classic hormones as well as with oncogenes. Furthermore, there are distinct families of growth factors based either on structural or functional similarities.

Download or read book The IGF System written by Ron G. Rosenfeld and published by Humana. This book was released on 2010-11-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Mechanisms of Lymphocyte Activation and Immune Regulation III written by Sudhir Gupta and published by Springer. This book was released on 1991-07-31 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in the understanding of the major events that shape the immune recog nition system have been remarkable. The analysis of immunoglobulin (Ig) gene organization and Ig repertoire diversification in lower vertebrates has provided new insight into this process in mammals. Similarly, the understanding of the early development of lymphocytes and of the acquisition of immunological tolerance has been aided by elegant studies in quail/chicken chimeras, using the power of the distinctive markers of the constitutive cells of these birds. Great strides have been made in understanding the role played by major histocompatibility complex (MHC) molecules in antigen presentation and in repertoire selec tion within the thymus. The use of transgenic mice expressing specific T-cell receptor (TCR) genes has elucidated the process of both positive and negative selection. In parallel, there has been considerable progress in our understanding of tolerance, based in part on the use of markers for the V fJ genes of T-cell receptors and in part on the analysis of the behavior of long term T-cell lines. This has led to the realization that both clonal deletion and clonal anergy may play critical roles in the maintenance of unresponsiveness to self antigen. Molecular analysis of the requirements for expression of membrane immunoglobulin molecules has revealed the existence of a complex that appears to be of critical importance in mediating signalling through Ig receptors. In addition, major insights have been obtained into the regulation of expression of genes of immunologic interest.

In this book an international group of contributors reviews the most up-to-date information on all aspects of the insulin-like growth factors, and critically discusses models for IGF action in their own systems. The book is a valuable source of information and ideas for researchers, and an accessible introduction to the subject for students and clinicians.
Download or read book Insulin Insulin like Growth Factors and Their Receptors in the Central Nervous System written by Mohan Raizada and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, intercellular communication and the regulation of biological functions of the body have been considered the role of two major and distinct systems: the nervous system and the endocrine system. The classic nervous system transmitted its signal rapidly by using electrical currents, whereas the signals used by the endocrine system were hormones produced by endocrine glands which reached the target tissues via the blood stream. During the past few decades, it has become apparent that these systems of intercellular com munication are not distinct and the signal messenger molecules are not unique to one or the other system. Many classic endocrine hormones are found in and act on nervous tissues and evidence exists for their de novo synthesis by neural related tissues. An exciting development in this area is the possibility that insulin and insulin-like growth factors (IGF) are not only produced by neural tissues but also exert profound physiological and biochemical effects on these tissues. The area of investigation of CNS insulin and IGF has been expanding rapidly and the availability of this book complete with up-to-date reviews on the subject by leaders in the field allows other scientists to utilize the knowledge in planning and adapting the latest ideas for future experiments. In addition, the book provides a collection of up-to-date articles for teachers to be used for the latest instructional material. The first section of the book covers general aspects of insulin receptors and insulin action.
