Download or read book Molecular Basis and Gene Therapies of Cystic Fibrosis written by John Engelhardt and published by MDPI. This book was released on 2020-12-11 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary of Genes. Thirty years ago, the gene responsible for cystic fibrosis (CF), a recessive genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator gene, was identified. This progress has considerably changed our understanding of the pathophysiology of CF and has paved the way for the development of novel and specific therapies for the disease. The CFTR gene contains 27 exons and is characterized by a frequent three base pair deletion of the p.Phe508del. As a result of collaborative work, today more than 2000 mutations have been reported in the gene, and their impact on protein function is now more evident and useful in designing new strategies to correct the gene defect. The field of gene therapy, as illustrated by Ziying Yan in this book, has worked on identifying an efficient vector system for the delivery of the wild-type CFTR gene to the lung. At the same time, animal models have been developed in mice, rats, rabbits, zebrafish, ferrets, and pigs to establish the efficacity of gene delivery. These animals are also of the utmost importance in testing new molecules as modulators or correctors to improve the CFTR lung function. During the last three decades, the epidemiology of CF has dramatically changed, as today cystic fibrosis is now a chronic adult pulmonary disease.

(Eva Yi) Chen and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2005 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cystic fibrosis (CF) is an autosomal disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (cftr) gene. Processing mutations, such as the deletion of Phe508 (DeltaF508), account for majority of CF cases. They cause the cftr gene product to be retained in the endoplasmic reticulum (ER). Correction of this processing defect has been the focus of much CF research. To understand the molecular basis of the processing defect, ER-trapped and cell surface-expressing wild-type (WT) CFTR were compared structurally and functionally with DeltaF508-CFTR. Expression of CFTR in the presence of MG-132, a proteasome inhibitor, trapped WT-CFTR in the ER in an altered structure similar to that of DeltaF508-CFTR. No chloride channel activity was detected when membrane containing the trapped protein was fused with planar lipid bilayers. A putative PEST sequence thought to contribute to the rapid degradation of CFTR proved to play no significant role in the degradation or processing of DeltaF508-CFTR. Multiple mutations to the PEST sequence, however, affect degradation and processing of WT-CFTR, possibly through disruption of folding. Individual endogenous cysteine residues of CFTR are not crucial to the overall structure of CFTR. Multiple mutations of the 18 endogenous cysteines to serine residues however had a cumulative effect on the processing of CFTR. Thus, a model is proposed for the folding and processing of CFTR. The model suggests that many missense mutations contribute to various degrees of local misfolding that may lead cumulatively to disruptions of interdomain interactions within the CFTR molecule, leading to its ER retention and misprocessing. Disulfide cross-linking analysis was used to compare the structures of wild-type and DeltaF508-CFTR. Cross-linking was detected in various CFTR cysteine mutants with cysteine residues introduced in transmembrane segments (TMs) 6 and 12. The disulfide cross-linking occurs intra-molecularly and is reducible by dithiothreitol. Introduction of the DeltaF508 mutation (DeltaF508-background) traps the cysteine mutants in the ER and disrupts cross-linking between TM6 and TM12. Cysteine mutants (WT-background) trapped by Brefeldin-A, a vesicular trafficking inhibitor, however retained cross-linking. This suggests that the presence of DeltaF508, a processing mutation in the nucleotide binding domain, can disrupt packing of the TM segments.

Download or read book Cystic Fibrosis Methods and Protocols written by William R. Skach and published by Springer Science & Business Media. This book was released on 2008-02-02 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the cloning of the cystic fibrosis transmembrane conductance re- lator (CFTR) nearly a decade ago, cystic fibrosis (CF) research has witnessed a dramatic expansion into new scientific areas. Basic researchers, clinicians, and patients increasingly rely on fundamental techniques of genetics, molecular biology, electrophysiology, biochemistry, cell biology, microbiology, and immunology to understand the molecular basis of this complex disease. Research into the pathophysiology of CF has established numerous paradigms of ion channel dysfunction that extend from inflammation and infection in the airways of patients to basic mechanisms of protein processing and regulation in intracellular components. With these rapid advances has come an increasing need for research scientists to understand and utilize a growing array of basic laboratory tools. This volume of Methods in Molecular Medicine, Cystic Fibrosis Methods and Protocols satisfies that need by providing detailed protocols for the laboratory techniques used throughout CF research. From electrophysiology and cell biology, to animal models and gene therapy, the comprehensive set of methods covered here provide step-by-step instructions needed for investigators to incorporate new approaches into their research programs. Contributions have been chosen to reflect the rich diversity of techniques and to provide a cohesive framework for understanding challenges that are currently at the forefront of CF research. It is hoped that this volume will serve as a valuable reference that will not only foster interdisciplinary investigations into current problems encountered in CF, but also facilitate the translation of new scientific discoveries into clinical solutions.

Download or read book CFTR and Cystic Fibrosis written by Carlos M. Farinha and published by Springer. This book was released on 2017-10-01 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Brief is devoted to the CFTR protein and cystic fibrosis, and it provides an updated perspective of the genetic, functional and cellular processes involved in this conformational disorder. Starting with a historical perspective on cystic fibrosis and its clinical features, the author departs into an in-depth description of the biology of the CFTR protein, ending with a discussion on the latest approaches aimed at developing corrective therapies for cystic fibrosis. First the basic aspects of cystic fibrosis as a disorder are addressed, focusing on genetics and mutation prevalence. Then the CFTR protein is discussed in detail: its structure and classification within the ABC transporter superfamily, its biogenesis with membrane insertion and chaperone assisted folding, its glycosylation and how it regulates the endoplasmatic reticulum quality control mechanisms that assess CFTR folding status. Extra attention is given to post-ER trafficking and regulation of membrane stability and anchoring, and to CFTR functions. This is linked to the molecular mechanisms through which different CFTR mutations cause cystic fibrosis. Finally, the different efforts aiming at rescuing the basic defect, most of which aim at repairing CFTR dysfunction, are covered. Through this integrated perspective, readers will obtain a unique insight into this fascinating membrane-bound protein and its associated disease. This Brief appeals to an audience interested in human genetics, protein folding, protein trafficking and physiology.

Download or read book Interactions Between the Transmembrane Helices of the Cystic Fibrosis Transmembrane Conductance Regulator CFTR microform written by Mei Yee Choi and published by National Library of Canada = Bibliothèque nationale du Canada. This book was released on 2004 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many membrane-based mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) involve introduction of a polar residue, which can lock helices together via a side chain-side chain interhelical non-native hydrogen bond to a neighboring wild type polar residue [i.e. Val 232-to-Asp (TM4) to Gln207 (TM3) (Therien, Grant & Deber, Nat. Struct. Biol., 2001]. We studied the Gln 207 H-bond 'capture potential' by performing an Asp 'walk' through TM4 in a series of TM3/4 helix-loop-helix (hairpin) constructs, assessing factors including the Asp position relative to the helix-helix interface, and side chain length and polarity. Diagnostic gel shift assays on SDS-PAGE were used to measure 'open-closed' states of each hairpin. In related experiments, L346P and R347P mutants were investigated in a TM5/6 hairpin to determine why R347P inserts properly in the membrane, while L346P does not. The overall results help explain the molecular basis for aberrant CFTR function in CF-phenotypic TM domain mutants.

This book was released on 2021-03-17 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clinical Pancreatology Since the book Clinical Pancreatology for Practising Gastroenterologists and Surgeons was first published sixteen years ago, the knowledge and clinical management of pancreatic diseases have developed markedly. Thanks to the development of the translational research and the from bench to bedside concept, much progress from the lab has been applied to clinical practice. In addition, several highly relevant clinical trials published over the last years have resulted in the update and optimisation of clinical guidelines. A new and validated classification of severity and complications of acute pancreatitis is firmly rooted in clinical practice and has been the basis for the development of minimally invasive approaches to pancreatic necrosis. The etiopathogenic knowledge of chronic pancreatitis and other pancreatopaties, like that associated with diabetes mellitus, has developed significantly. Especially important has been the development of the field of cystic pancreatic tumours, which has been reflected in the publication of several guidelines and consensus reports over the last few years. Most research efforts have focused on pancreatic cancer, which have led and will further lead to a significant increase in the therapeutic armamentarium against this devastating disease. Finally, many newly published studies have changed the concept, causes, clinical relevance, diagnosis and treatment of exocrine pancreatic insufficiency. This new edition of Clinical Pancreatology for Practising Gastroenterologists and Surgeons has enjoyed the collaboration of the world’s leading experts in each of the areas of clinical pancreatology with the aim of facilitating gastroenterologists, surgeons, oncologists, internists, nutritionists, diabetologists, paediatricians, radiologists, pathologists and other specialists in their decision making when facing patients with pancreatic diseases in their daily clinical practice. All in all, this book supplies an indispensable update of the relevant aspects of clinical pancreatology.
