Fibroblast Growth Factor 23

Fibroblast Growth Factor 23 describes how FGF23 was initially identified as a bone-derived factor targeting the kidney. As such, sections in this comprehensive book cover exciting research that shows that different FGF23 effects require distinct signaling receptors and mediators that differ among target tissues, cover FGF23 initially identified as a bone-derived factor targeting the kidney, look at FGF23 as a regulator of phosphate metabolism and beyond, and cover research on novel concepts of FGF receptor signaling. Additional sections cover biochemistry, pharmacology and nephrology, making this book an ideal reference source on FGF23. Provides a comprehensive collection of chapters on the diversity of FGF23's actions Highlights truly translational topics, from molecular signaling to physiology and mechanism of disease, discussing cell culture and animal models to study FGF23 Describes FGF23’s potential in the clinical setting as a biomarker or even drug target Presents leaders in the field who cover a wide spectrum of research backgrounds and expertise, including clinical and basic scientists who specialize in diseases, endocrinology, genetics, protein biochemistry, cell biology and physiology

We present to our readers the proceedings of the Second International Workshop on Phosphate. A short account of the history of the effort led to the Phosphate Workshops is appro priate and can be of interest to the reader. The idea for Phosphate Workshops was born in the early days of November, 1974. One of us (S. G. M. ) suggested the thought to a group of scientists gathered for a luncheon in one of the attrac tive small restaurants in Weisbaden, Germany. The purpose of the workshop was to bring together interested scientists to discuss the newer developments and the recent advances in the field of phosphate metabolism and the other related minerals. An Organizing Committee made of Shaul G. Massry (USA), Louis V. Avioli (USA), Philippe Bordier (France), Herbert Fleisch (Switzerland), and Eduardo Slatopolsky (USA) was formed. The First Workshop was held in Paris during June 5-6, 1975 and was hosted by Dr. Philippe Bordier. Its proceeding was already published. The Second Workshop took place in Heidelberg during June 28-30, 1976 and was hosted by Dr. Eberhard Ritz. Both of these workshops were extremely successful scientific endeavors, and the need for them was demonstrated by the great interest they generated among the scientific community. The Or ganizing Committee, therefore, decided to continue with the tradi tion to hold additional Workshops annually or every other year.

Fibroblast growth factors (FGFs) have been recognized primarily as autocrine/paracrine factors that regulate embryonic development and organogenesis. However, recent studies have revealed that some FGFs function as endocrine factors and regulate various metabolic processes in adulthood. Such FGFs, collectively called endocrine FGFs, are comprised of three members (FGF15/19, FGF21, and FGF23: FGF15 is the mouse ortholog of human FGF19). These endocrine FGFs share a common structural feature that enables the endocrine mode of action at the expense of the affinity to FGF receptors. To restore the affinity to FGF receptors in their target organs, the endocrine FGFs have designated the Klotho family of transmembrane proteins as obligate co-receptors. By expressing Klothos in a tissue-specific manner, this unique co-receptor system also enables the endocrine FGFs to specify their target organs among many tissues that express FGF receptors.

Fibroblast growth factor 23 (FGF-23), is recently discovered phosphaturic substance. It releases from bone osteocytes and plays a key role in the physiological regulation of phosphate metabolism. Excessive action of FGF23 results in several hypophosphatemic diseases characterized by impaired renal tubular phosphate reabsorption. In contrast, deficient action of FGF23 causes familial hyperphosphatemic tumoral calcinosis with enhanced renal tubular phosphate reabsorption. We carried out this study to gain knowledge about the current status of FGF-23 levels in our population and its relationship with serum phosphate; TmP/GFR and dietary phosphate; which has implications for the diagnosis and treatment of phosphate-wasting disorders and may guide us in planning further studies to see its role and implications on vitamin D metabolism.

The number of dialysis patients, and their ages, continues to increase globally. This creates major issues such as rising medical costs in an aging population, how to best manage end-of-life care, and how to train the various practitioners involved in dialysis care. After the US and China, Japan occupies 3rd place with regard to the number of dialysis patients and is also widely regarded as a world leader in dialysis. This book contains selected articles – organized into 4 chapters - that discuss recent advances in dialysis therapy in Japan. Chapter 1 presents insights into causes, risk factors, disease associations, and possible implications for management of dialysis patients. Chapter 2 examines recent progress in hemodialysis treatment, and chapter 3 focuses on developments in peritoneal dialysis. The final chapter concentrates on recent advances in apheresis and current trends in practice, among other topics. This book is aimed at nephrologists, physicians, urologists, nurses, clinical engineers, pharmacists, and nutritionists. It is a significant contribution to furthering the progress of dialysis therapy worldwide.

Fibroblast Growth Factors, Second Edition systematically introduces readers to FGF in the fields of injury repair and regeneration, endocrinology and metabolism, structure and modification, pharmaceutics, pharmacology, FGF/FGFR inhibitor, engineering and new drug development. Fibroblast growth factors (FGFs) are secreted protein ligands that act in a paracrine or endocrine fashion to carry out their pleiotropic functions in development, tissue homeostasis and metabolism. This book covers the work from Li’s team from 2013 to 2018 and will be a primer for scientists, particularly young students entering the FGFs field with an eye on basic research and application. Contains approximately 90% new material on topics covered Includes information on “breakthrough discoveries which have been made since the publication of the first edition Introduces detailed research methods and technologies of FGFs so the book can be used as a “toolbox by the user Includes comprehensive and systematic research and industry application
