Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a highly prevalent hereditary renal disorder in which fluid-filled cysts are appeared in both kidneys. Main causative genes of ADPKD are PKD1 and PKD2, encoding for polycystin-1 (PC1) and polycystin-2 (PC2) respectively. Those proteins are localized on primary cilia and function as mechanosensor in response to the fluid flow, translating mechanistic stimuli into calcium signaling. With mutations either of PKD1 or PKD2, hyper-activated renal tubular epithelial cell proliferation is observed, followed by disrupted calcium homeostasis and aberrant intracellular cyclic AMP (cAMP) accumulation. Increased cell proliferation with fluid secretion leads to the development of thousands of epithelial-lined, fluid-filled cysts in kidneys. It is also accompanied by interstitial inflammation, fibrosis, and finally reaching end-stage renal disease (ESRD). In human ADPKD, the age at which renal failure typically occurs is later in life, however no specific targeted medications are available to cure ADPKD. Recently, potential therapeutic targets or surrogate diagnostic biomarkers for ADPKD are proposed with the advances in the understanding of ADPKD pathogenesis, and some of them were attempted for clinical trials. Herein, we will summarize genetic and epi-genetic molecular mechanisms in ADPKD progression, and overview the currently available biomarkers or potential therapeutic reagents suggested.

This volume focuses on the investigatory methods applied to autosomal dominant polycystic kidney disease (ADPKD), one of the most common human genetic diseases. ADPKD is caused by mutations in PKD1 and TRPP2, two integral membrane proteins that function as receptor/ion channels in primary cilia of tubular epithelial cells. Thus, ADPKD belongs to ciliopathies, a group of disorders caused by abnormal cilia formation or function. This proposed book will cover the state-of-the-art methods ranging from molecular biology, biochemistry, electrophysiology, to tools in model animal studies. Key Features Explores the role of cilia in polycystic kidney disease Focuses on myriad state-of-the-art methods and techniques Reviews specific mutations integral to this autosomal genetic disease Includes discussions of model systems

This book reviews important aspects of polycystic kidney diseases, the latest scientific understanding of the diseases and syndromes, along with the therapies being developed. Cystic kidney diseases comprise a spectrum of genetic syndromes defined by renal cyst formation and expansion with variable extrarenal manifestations. The most prevalent disorder is the autosomal dominant polycystic kidney disease (ADPKD). It is the most common monogenetic disorder in humans and accounts for 4.4% of end-stage renal disease (ESRD) cases in the U.S. Patients inevitably progress to ESRD and require renal replacement therapy in the form of dialysis or transplantation. Through advancements in genomics and proteomics approaches, novel genes responsible for cystic diseases have been identified, further expanding our understanding of basic mechanisms of disease pathogenesis. The hallmark among all cystic genetic syndromes is the formation and growth of fluid-filled cysts, which originate from tubular epithelia of nephron segments. Cysts are the disease, and treatment strategies are being developed to target prevention or delay of cyst formation and expansion at an early stage, however no such therapy is currently approved.

This is a book about renal cysts and cystic kidneys. Its contributors have created a resource of current information in a field that once aroused only curiosity, but that now stands at the leading edge of molecular nephrology. Its authorship includes 'oldtimers', who bring the wisdom of experience, and 'newcomers', whose presence attests to the contributions made by the investigative and technological advances of the past decade. Its text is organized to carry the reader from renal cyst to cystic renal disease. Each of its chapters defines or explores a challenge or an advance. Cells that line renal cysts are diverse in structure, type, and perhaps function. The cysts themselves lie within an interstitium that is not normal and may influence cyst development and growth. Experimental analogs of human disease offer increasing opportunities to basic researchers to examine, in sequence and under controlled circumstances, those events that favor nephron dilation, cyst growth and ultimate renal failure.

Polycystic kidney disease (PKD) is characterized by the presence of fluid-filled cysts in the kidneys. It is the fourth most common cause of chronic renal insufficiency or end-stage kidney disease. This book focuses on the basic and clinical aspects of the burgeoning PKD research under three sections. Section 1 provides a comprehensive guide to the diagnosis, management and treatment of PKD. Section 2 covers most of the fundamental molecular and cellular mechanisms underlying PKD, and how this knowledge is contributing to the development of potential novel therapeutic agents. Finally, section 3 focuses on extra-renal or secondary complications of PKD.

This book systemically presents the latest research on renal fibrosis, covering all the major topics in the field, including the possible mechanisms, biomarkers, and strategies for prevention and treatment of chronic kidney disease (CKD). Due to its high prevalence, CKD represents a huge global economic and social burden. Irrespective of the initial causes, CKD progresses to end stage kidney disease (ESKD) due to renal fibrosis, which is characterized by glomerulosclerosis, tubule atrophy and atresia, and the excessive accumulation of extracellular matrix (ECM) in the kidney. Unfortunately, an estimated 1%-2% of the adult population living with CKD will need renal replacement therapy at some point as a result of ESKD. As such, strategies for preventing or slowing CKD progression to ESKD are of utmost importance, and studies aiming to understand the mechanisms of renal fibrosis have been the focus of intensive research. Recently, novel insights into the pathophysiological processes have furthered our understanding of the pathogenesis of renal fibrosis, and more importantly, promoted studies on the early diagnosis and treatment of CKD. This book draws lessons from the extensive, state-of-the-art research in this field, elaborating the new theories and new techniques to offer readers a detailed and comprehensive understanding of renal fibrosis and as well as inspiration for future research directions.
