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.







Mechanisms of Insulin Action


Book Description

More than 18 million people in the United States have diabetes mellitus, and about 90% of these have the type 2 form of the disease. This book attempts to dissect the complexity of the molecular mechanisms of insulin action with a special emphasis on those features of the system that are subject to alteration in type 2 diabetes and other insulin resistant states. It explores insulin action at the most basic levels, through complex systems.




Insulin Action


Book Description

In 1996 the 75th anniversary of the discovery of insulin was celebrated at the University of Toronto, the scene of that discovery in 1921. This volume was stimulated by the scientific program which was staged at that time and brought together much of the world's best talent to discuss and analyze the most recent developments in our understanding of pancreatic function, insulin secretion, the interaction of insulin with its target tissues, the mechanism of insulin action at the cellular level, and the defects which underlie both Type I (insulin-dependent diabetes mellitus, IDDM) and Type II (noninsulin-dependent diabetes mellitus, NIDDM) forms of the disease. We have chosen to focus the present volume on work related to insulin action.




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.
