This book highlights the important role free fatty acids (FFA) play as potential drug targets. While FFA have long been considered byproducts of cell metabolism, they are now recognized as ligands that regulate cell and tissue function via G-protein-coupled receptors. At least three receptors have been identified for which FFA appear to be the endogenous ligands.

This volume provides comprehensive coverage of the current knowledge of the physiology of the endocrine system and hormone synthesis and release, transport, and action at the molecular and cellular levels. It presents essential as well as in-depth information of value to both medical students and specialists in Endocrinology, Gynecology, Pediatrics, and Internal Medicine. Although it is well established that the endocrine system regulates essential functions involved in growth, reproduction, and homeostasis, it is increasingly being recognized that this complex regulatory system comprises not only hormones secreted by the classic endocrine glands but also hormones and regulatory factors produced by many organs, and involves extensive crosstalk with the neural and immune system. At the same time, our knowledge of the molecular basis of hormone action has greatly improved. Understanding this complexity of endocrine physiology is crucial to prevent endocrine disorders, to improve the sensitivity of our diagnostic tools, and to provide the rationale for pharmacological, immunological, or genetic interventions. It is such understanding that this book is designed to foster.

Recent advances in molecular and cell biology enabling the cloning, expression, and mutagenesis of signal transduction proteins has prompted an explosion of knowledge in the field of receptor regulation, facilitating the discovery of new classes of regulatory proteins, and providing a basis and means for manipulating receptor function through multiple intracellular targets. This volume covers methods used to examine how the function(s) of receptors are regulated. Understanding how to regulate the function and expression of these receptors is critical in determining how to modify receptors and to translocating receptors away from the cell surface and its recycling. Individual chapters focus on specific techniques used to characterize receptors (epitope tagging, measurement and analysis of receptor phosphorylation, analysis of the kinetics of receptor desensitization, and assessment of receptor/G protein coupling); the role of regulatory proteins (receptor kinases and phosphatases, arrestins) in modulating receptor function; and the methods used to measure receptor trafficking (ligand binding, immunofluoresence) and expression (transcriptional and translational regulation). * Covers a broad range of important concepts and methodologies which are current in the study of G protein-coupled receptors (GPCRs) * G-protein coupled receptors make up over 40% of the current pharmacological targets * Provides detailed protocols for executing various strategies and offers informed judgments as to what approaches are and aren't useful * Volume Editor, Jeffrey Benovic, is a dominant world leader in the study of receptor regulation of GPCR kinases and is highly respected in the field

This book provides a comprehensive compilation of the evidence available regarding the role of genetic differences in the etiology of human obesities and their health and metabolic implications. It also identifies the most promising research areas, methods, and strategies for use in future efforts to understand the genetic basis of obesities and their consequences on human health. Leading researchers in their respective fields present contributed chapters on such topics as etiology and the prevalence of obesities, nongenetic determinants of obesity and fat topography, and animal models and molecular biological technology used to delineate the genetic basis of human obesities. A major portion of the book is devoted to human genetic research and clinical observations encompassing adoption studies, twin studies, family studies, single gene effects, temporal trends and etiology heterogeneity, energy intake and food preference, energy expenditure, and susceptibility to metabolic derangements in the obese state. Future directions of research in the field are covered in the book as well.

Cardiovascular and metabolic diseases remain the number one cause of death in developed countries and their prevalence is increasing rapidly in developing nations. This book brings together the recent information on these disorders and the links that exist between them in order to provide a complete picture of drug discovery for these conditions. The main three sections comprehensively discuss obesity, hypertension and cardiovascular disease, and diabetes in turn, following an introduction to the molecular links between them. The final chapter provides perspectives on future directions of the field. Chapters are contributed by leaders in the field from academia and industry and cover biomarkers, risk factors, gene-environment interactions, therapies and the various types of animal models that have been used to study each disease. Case studies describing the implementation of animal models in drug development further enhance the book’s usefulness as a comprehensive guide to this important therapeutic area. Providing a full picture of the various types of animal models that have been used to study obesity, hypertension, and insulin resistance with recent case studies, this book provides a valuable resource for medicinal chemists and clinicians working in these disease areas.

This timely and most comprehensive reference available on the topic covers all the different aspects vital in the fight against the global obesity epidemic. Following a look at adipose tissue development and morphology, the authors go on to examine its metabolic and endocrine functions and its role in disease. The final section deals with comparative and evolutionary aspects of the tissue. The result is an essential resource for cell and molecular biologists, physiologists, biochemists, pharmacologists, and those working in the pharmaceutical industry.

The Islets of Langerhans: Biochemistry, Physiology, and Pathology reviews the state of knowledge in the complex phenomena involved in the functioning of the multiendocrine organ, the islet of Langerhans, and the various influences that can lead to its abnormal functioning. The volume highlights major gaps in knowledge and indicates the directions for research on the major functioning of this organ and the defects leading to its major pathology, diabetes mellitus. The book is organized into three parts. Part I provides the necessary background information on the nature and development of the islet of Langerhans. It includes studies on the evolution of knowledge of the ever-increasing number of cell types found in islet tissue; and fetal development of the functional capacities of the islet cells. Part II is devoted to the synthesis and secretion of islet hormones, beginning with a chapter on the membrane transport systems of islet tissue as a prelude to subsequent examination of their role in the regulation of these processes. Part III examines the effects of deleterious conditions and agents on the morphology and function of islet cells. This book is intended for researchers in endocrinology, particularly those interested in pancreatic hormones, graduate students in endocrinology, and medical endocrinologists interested in diabetes. It will also be useful to physiologists and biochemists studying peptide synthesis and secretion.
