Molecular and Cell Biology of Type 2 Diabetes and Its Complications


Book Description

The present volume summarizes current research on type 2 diabetes, its etiology, pathogenesis and long-term vascular and neurological consequences, with special emphasis on molecular and biochemical mechanisms. Alterations in insulin secretion are comprehensively treated, focusing on the role of glucokinase as glucose sensor. Moreover, insulin action is analyzed with regard to both nonoxidative glucose utilization and glucose oxidation. Concerning the complications in chronic diabetes, topics covered include the effects of high glucose concentration on cellular and endothelial functions and on the glucose phosphorylation rate in non-insulin-sensitive tissues. Furthermore, the role of oxidative stress and advanced glycation end products as well as the significance of alterations in lipoprotein structure are considered. Finally, the pericyte loss in retinopathy and microalbuminuria as related to cardiovascular risk are discussed. Taken as a whole, the contributions included in this book represent a large body of information that will be of great interest to diabetologists, endocrinologists and internists interested in both the basic and clinical aspects of diabetes and its complications.



















Molecular Biology of Diabetes


Book Description

In a rapidly evolving and extremely important area of medical science, it is often difficult for the student, teacher, and researcher to keep abreast of all the important advances. The purpose of Molecular Biology ofDiabetes, Parts I and II is to bring to these individuals the latest knowledge of diabetes-related research in a comprehensive, yet concise manner. To this end, we have assembled chapters, written by most of the world's experts in the field, that we believe compre hensively survey and synthesize a coherent understanding of the subject. Studies of the etiology of type I and type II diabetes are extremely exciting and essential, since we hope to one day prevent the disease using gene therapy. These aspects are covered in Molecular Biology of Diabetes: I. Autoimmunity and Genetics; Insulin Synthesis and Secretion. In type II diabetes, an abnormality in pancreatic secretion exists concomitantly with peripheral insulin resistance. This abnor mality of insulin secretion is believed to be related to a defect(s) in glucose sensing. Uncoupling of glucose sensing from insulin secre tion may be the crucial step in the pathogenesis of noninsulin-depen dent diabetes. In this volume, we have invited authors to describe their studies on all known factors affecting ~-cell function, including autoimmunity and genetics of diabetes, as well as molecular mecha nisms of insulin synthesis and secretion. In the last few years, the most rapidly advancing area of research in diabetes has been, in fact, related to insulin action.




Type 1 Diabetes


Book Description

In the field of immunology, type 1 diabetes has become one of the major areas of investigation with studies that span from characterization of key molecules to trials for the prevention of the disease. Type 1 Diabetes : Molecular, Cellular and Clinical Immunology communicates both the background and the most recent understanding of this disorder, which will almost certainly be central to elucidating the etiology of autoimmunity, and in particular of organ specific autoimmunity. The book covers immunogenetics, immunopathogenesis, epidemiology, disease prediction and clinical application of current knowledge. Both scientists seeking to understand and prevent type 1 diabetes/autoimmunity as well as physicians caring for families with type 1 diabetes will be interested in this book.




Molecular Nutrition and Diabetes


Book Description

Molecular Nutrition and Diabetes: A Volume in the Molecular Nutrition Series focuses on diabetes as a nutritional problem and its important metabolic consequences. Fuel metabolism and dietary supply all influence the outcome of diabetes, but understanding the pathogenesis of the diabetic process is a prelude to better nutritional control. Part One of the book provides general coverage of nutrition and diabetes in terms of dietary patterns, insulin resistance, and the glucose-insulin axis, while Part Two presents the molecular biology of diabetes and focuses on areas such as oxidative stress, mitochondrial function, insulin resistance, high-fat diets, nutriceuticals, and lipid accumulation. Final sections explore the genetic machinery behind diabetes and diabetic metabolism, including signaling pathways, gene expression, genome-wide association studies, and specific gene expression. While the main focus of each chapter is the basic and clinical research on diabetes as a nutritional problem, all chapters also end with a translational section on the implications for the nutritional control of diabetes. Offers updated information and a perspective on important future developments to different professionals involved in the basic and clinical research on all major nutritional aspects of diabetes mellitus Explores how nutritional factors are involved in the pathogenesis of both type1 and type2 diabetes and their complications Investigates the molecular and genetic bases of diabetes and diabetic metabolism through the lens of a rapidly evolving field of molecular nutrition




Biochemistry of Diabetes and Atherosclerosis


Book Description

Diabetes is an autoimmune, inflammatory disease affecting many different organ systems and exhibiting both primary and secondary defects. Because diabetes affects a wide range of cellular systems, a multidisciplinary effort has been mounted over the past several decades using a wide range of investigative techniques and methodologies in order to identify molecular mechanisms responsible for cellular dysfunction. Because primary defects at various levels of sub-cellular signaling, intracellular calcium handling, protein expression and energy regulation are often a primary consequence of diabetes. This volume is a compilation of new multidisciplinary research that will broaden our current understanding of diabetes and cardiovascular disease as well as provide the basis for the development of novel therapeutic interventions.
