Download or read book Nonsense Mutation Correction in Human Diseases written by Fabrice Lejeune and published by Academic Press. This book was released on 2016-02-26 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonsense Mutation Correction in Human Diseases: An Approach for Targeted Medicine provides an introduction on genetic diseases, discusses the prevalence of nonsense mutations, the consequences of a nonsense mutation for the expression of the mutant gene, and the presentation of the nonsense-mediated mRNA decay (NMD). It presents the mechanism of action and rationale associated with each strategy to correct nonsense mutations with the results of clinical trials to further support this basis. In addition, the book shows how it may be possible to combine several of these strategies to ultimately improve the efficiency of correction, also suggesting the future goals and objectives to improve treatment modalities in this evolving sphere of personalized medicine. Features basic biological and clinical constructs that inform the application of genomic data to clinical decision-making Includes theories and methods that can be used to link bio-molecular and clinical phenotypes so as to enable integrative hypothesis discovery, testing, and downstream evidence-based practice Provides design patterns and use cases that contextualize the clinical decision-making and evidence-based practice relative to real world requirements and stakeholders

Download or read book Study of Molecules with Nonsense Mutation Correction Capacity written by Jieshuang Jia and published by . This book was released on 2015 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonsense mutations represent approximately 10% of mutations found in the inherited geneticdiseases. mRNAs harboring a nonsense mutation are rapidly degraded by a quality-controlmechanism called nonsense-mediated mRNA decay (NMD) to prevent the synthesis of toxic or nonfunctionaltruncated proteins. Some stratégies have been developed to correct nonsense mutations.In our lab, we study 2 of them which are (i) the NMD inhibition and (ii) the PTC-readthroughactivation which is a mechanism leading to the incorporation of an amino-acid at the PTC position. Todesign new therapeutic tools for the inherited genetic diseases, our lab tested molecules byscreening to find ones with the capacity of NMD inhibition. For each molecules selected in thescreen, we measure the efficiency of NMD inhibition and PTC-readthrough activation of thesemolecules in cell lines harboring a nonsense mutation. We have shown that amlexanox not onlyinhibits NMD but also activâtes PTC readthrough. But the efficacy of amlexanox is still low. Wewanted to find other families of molecules capable of rescuing the expression of nonsense mutationcontainingmRNA with a higher efficacy or with some specificity. In my study, I found two spécialfamilies, one is the family of apoptosis inducers and the other is the family of cytoskeleton inhibitors.I found that apoptosis inducers can inhibit NMD by activating caspase pathway and cleave NMDfactors (UPF1 and UPF2). I also found that cytoskeleton inhibitors can inhibit NMD and some of themcan activate PTC-readthrough by inducing NMD factors (UPF1 or/and UPF3X) to concentrate in Pbodiesor in other cytoplasmic foci. The efficiencies of these molecules on NMD inhibition are similaror higher than amlexanox. Apoptosis inducers and cytoskeleton inhibitors demonstrated thatmolecules which can inhibit NMD or/and activate PTC-readthrough can be found and candemonstrate a higher correction of nonsense mutation efficiency than the existing molecules(ataluren or amlexanox for example).

Download or read book An Evidence Framework for Genetic Testing written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-04-21 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in genetics and genomics are transforming medical practice, resulting in a dramatic growth of genetic testing in the health care system. The rapid development of new technologies, however, has also brought challenges, including the need for rigorous evaluation of the validity and utility of genetic tests, questions regarding the best ways to incorporate them into medical practice, and how to weigh their cost against potential short- and long-term benefits. As the availability of genetic tests increases so do concerns about the achievement of meaningful improvements in clinical outcomes, costs of testing, and the potential for accentuating medical care inequality. Given the rapid pace in the development of genetic tests and new testing technologies, An Evidence Framework for Genetic Testing seeks to advance the development of an adequate evidence base for genetic tests to improve patient care and treatment. Additionally, this report recommends a framework for decision-making regarding the use of genetic tests in clinical care.

Download or read book Health Risks from Exposure to Low Levels of Ionizing Radiation written by Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation and published by National Academies Press. This book was released on 2006-03-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the seventh in a series of titles from the National Research Council that addresses the effects of exposure to low dose LET (Linear Energy Transfer) ionizing radiation and human health. Updating information previously presented in the 1990 publication, Health Effects of Exposure to Low Levels of Ionizing Radiation: BEIR V, this book draws upon new data in both epidemiologic and experimental research. Ionizing radiation arises from both natural and man-made sources and at very high doses can produce damaging effects in human tissue that can be evident within days after exposure. However, it is the low-dose exposures that are the focus of this book. So-called “late” effects, such as cancer, are produced many years after the initial exposure. This book is among the first of its kind to include detailed risk estimates for cancer incidence in addition to cancer mortality. BEIR VII offers a full review of the available biological, biophysical, and epidemiological literature since the last BEIR report on the subject and develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation.

Download or read book Astrocytes in Patho Physiology of the Nervous System written by Vladimir Parpura and published by Springer Science & Business Media. This book was released on 2008-12-11 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrocytes were the original neuroglia that Ramón y Cajal visualized in 1913 using a gold sublimate stain. This stain targeted intermediate filaments that we now know consist mainly of glial fibrillary acidic protein, a protein used today as an astrocytic marker. Cajal described the morphological diversity of these cells with some ast- cytes surrounding neurons, while the others are intimately associated with vasculature. We start the book by discussing the heterogeneity of astrocytes using contemporary tools and by calling into question the assumption by classical neuroscience that neurons and glia are derived from distinct pools of progenitor cells. Astrocytes have long been neglected as active participants in intercellular communication and information processing in the central nervous system, in part due to their lack of electrical excitability. The follow up chapters review the “nuts and bolts” of ast- cytic physiology; astrocytes possess a diverse assortment of ion channels, neu- transmitter receptors, and transport mechanisms that enable the astrocytes to respond to many of the same signals that act on neurons. Since astrocytes can detect chemical transmitters that are released from neurons and can release their own extracellular signals there is an increasing awareness that they play physiological roles in regulating neuronal activity and synaptic transmission. In addition to these physiological roles, it is becoming increasingly recognized that astrocytes play critical roles during pathophysiological states of the nervous system; these states include gliomas, Alexander disease, and epilepsy to mention a few.

Download or read book The Collagen Superfamily and Collagenopathies written by Florence Ruggiero and published by Springer Nature. This book was released on 2021-05-15 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims at providing insights into the collagen superfamily and the remarkable diversity of collagen function within the extracellular matrix. Additionally, the mechanisms underlying collagen-related diseases such as dystrophic epidermolysis bullosa, osteogenesis imperfecta, as well as collagen-related myopathies and neurological disorders are discussed. Collagens are the most abundant extracellular matrix proteins in organisms. Their primary function is to provide structural support and strength to cells and to maintain biomechanical integrity of tissues. However, collagens can no longer be considered just as structural proteins. They can act as extracellular modulators of signaling events and serve critical regulatory roles in various cell functions during embryonic development and adult homeostasis. Furthermore, collagens are associated with a broad spectrum of heritability-related diseases known as “collagenopathies” that affect a multitude of organs and tissues including sensorial organs. The book is a useful introduction to the field for junior scientists, interested in extracellular matrix research. It is also an interesting read for advanced scientists and clinicians working on collagens and collagenopathies, giving them a broader view of the field beyond their area of specialization.

Download or read book The Prion Protein written by Jorg Tatzelt and published by . This book was released on 2010 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: A conformational transition of the cellular prion protein (PrPC) into an aberrantly folded isoform designated scrapie prion protein (PrPSc) is the hallmark of a variety of neurodegenerative disorders collectively called prion diseases. They include Creutzfeldt-Jakob disease and Gerstmann-Stäussler-Scheinker syndrome in humans, scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle and chronic wasting disease (CWD) in free-ranging deer. In contrast to the deadly properties of misfolded PrP, PrPC seems to possess a neuroprotective activity. More-over, animal models indicated that the stress-protective activity of PrPC and the neurotoxic effects of PrPSc are somehow interconnected. In this timely book, leading scientists in the field have come together to highlight the apparently incongruous activities of different PrP conformers. The articles outline current research on celluar pathways implicated in the formation and signaling of neurotoxic and physiological PrP isoforms and delineate future research direction. Topics covered include the physiologcial activity of PrPC and its possible role as a neurotrophic factor, the finding that aberrant PrP conformers can cause neurodegeneration in the absence of infectious prion propagation, the requirement of the GPI anchor of PrPC for the neurotoxic effects of scrapie prions, the pathways implicated in the formation and neurotoxic properties of cytosolically localized PrP, the impact of metal ions on the processing of PrP, and the role of autophagy in the propagation and clearance of PrPSc. The book is fully illustrated and chapters include comprehensive reference sections. Essential reading for scientists involved in prion research.
