Book Description
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

Book Description
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).

Book Description
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.

Book Description
Specific complexes of protein and RNA carry out many essential biological functions, including RNA processing, RNA turnover, and RNA folding, as well as the translation of genetic information from mRNA into protein sequences. Messenger RNA (mRNA) decay is now emerging as an important control point and a major contributor to gene expression. Continuing identification of the protein factors and cofactors and mRNA instability elements responsible for mRNA decay allow researchers to build a comprehensive picture of the highly orchestrated processes involved in mRNA decay and its regulation. * Covers the nonsense-mediated mRNA decay (NMD) or mRNA surveillance pathway * Expert researchers introduce the most advanced technologies and techniques * Offers step-by-step lab instructions, including necessary equipment and reagents

Book Description
A comprehensive review of contemporary antisense oligonucleotides drugs and therapeutic principles, methods, applications, and research Oligonucleotide-based drugs, in particular antisense oligonucleotides, are part of a growing number of pharmaceutical and biotech programs progressing to treat a wide range of indications including cancer, cardiovascular, neurodegenerative, neuromuscular, and respiratory diseases, as well as other severe and rare diseases. Reviewing fundamentals and offering guidelines for drug discovery and development, this book is a practical guide covering all key aspects of this increasingly popular area of pharmacology and biotech and pharma research, from the basic science behind antisense oligonucleotides chemistry, toxicology, manufacturing, to safety assessments, the design of therapeutic protocols, to clinical experience. Antisense oligonucleotides are single strands of DNA or RNA that are complementary to a chosen sequence. While the idea of antisense oligonucleotides to target single genes dates back to the 1970's, most advances have taken place in recent years. The increasing number of antisense oligonucleotide programs in clinical development is a testament to the progress and understanding of pharmacologic, pharmacokinetic, and toxicologic properties as well as improvement in the delivery of oligonucleotides. This valuable book reviews the fundamentals of oligonucleotides, with a focus on antisense oligonucleotide drugs, and reports on the latest research underway worldwide. • Helps readers understand antisense molecules and their targets, biochemistry, and toxicity mechanisms, roles in disease, and applications for safety and therapeutics • Examines the principles, practices, and tools for scientists in both pre-clinical and clinical settings and how to apply them to antisense oligonucleotides • Provides guidelines for scientists in drug design and discovery to help improve efficiency, assessment, and the success of drug candidates • Includes interdisciplinary perspectives, from academia, industry, regulatory and from the fields of pharmacology, toxicology, biology, and medicinal chemistry Oligonucleotide-Based Drugs and Therapeutics belongs on the reference shelves of chemists, pharmaceutical scientists, chemical biologists, toxicologists and other scientists working in the pharmaceutical and biotechnology industries. It will also be a valuable resource for regulatory specialists and safety assessment professionals and an important reference for academic researchers and post-graduates interested in therapeutics, antisense therapy, and oligonucleotides.
