Book Description :

To create and establish mutant mice as models for human diseases and traits, various forward and reverse genetics tools are currently available. Newly developed tools of high-throughput identification of novel mutations and site-directed mutagenesis, or gene targeting, in the mouse genome have caused forward and reverse genetics, respectively, to rapidly expand during the last two decades. Worldwide efforts including a variety of international consortiums have been producing many useful mutant mouse strains for functional genomics to elucidate the mechanisms behind diseases and traits. Resource centers and public databases have also been built to enhance their utilities. The modeling has started from Mendelian monogenic traits and has expanded to more complex quantitative traits as well. Multidisciplinary integration among, for example, molecular, cellular, and developmental biology; genetics; genomics; medicine; statistics; and informatics must be orchestrated to fully utilize the resources and knowledge of model mice.

Book Description :

Genome-wide association (GWA) studies and tumor-specific epigenome, transcriptome and genome sequencing projects are generating an ever-growing list of susceptibility alleles, as well as putative gain- and loss-of-function gene mutations associated with cancer. These genetic changes ultimately need to be validated to determine their contribution to the initiation, progression and likelihood of treatment response for various cancers. The bottle-neck is no longer obtaining sequence data or completion of the GWA studies, but rather the ability efficiently to validate candidate genes identified by these projects. In vivo studies in animal models are the “gold standard” for validation of these candidate drivers and modifiers of cancer. Furthermore, once a gene product or molecular pathway has been validated as playing an important role in the development or progression of cancer, animal models provide the necessary preclinical data for evaluation of the efficacy and toxicity of new therapeutics targeting that gene or pathway. As such, animal models play an essential role in cancer research by facilitating the translation of genomic discoveries into preclinical studies that precede new targeted therapies for cancer. In this chapter, we will discuss vertebrate and invertebrate animal models as they apply to cancer genomics, as well as key technologies employed. In particular, we will focus on the use of murine and zebrafish human tumor xenografts and transgenic models.

Book Description :

Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.

Precision medicine is focused on the individual and will require the rapid and accurate identification and prioritization of causative factors of disease. To move forward and accelerate the delivery of the anticipated benefits of precision medicine, developing predictable, reproducible, and reliable animal models will be essential. In order to explore the topic of animal-based research and its relevance to precision medicine, the National Academies of Sciences, Engineering, and Medicine convened a 2-day workshop on October 5 and 6, 2017. The workshop was designed to focus on the development, implementation, and interpretation of model organisms to advance and accelerate the field of precision medicine. Participants examined the extent to which next-generation animal models, designed using patient data and phenotyping platforms targeted to reveal and inform disease mechanisms, will be essential to the successful implementation of precision medicine. This publication summarizes the presentations and discussions from the workshop.

Book Description :

Drs. Greek have written 2 books on why using animals as models for humans is not the best way to conduct medical research and drug testing. During their lectures and debates, the most commonly asked question was, "Well. What will we use if we don't use animals?" What Will We Do If We Don't Experiment On Animals? Medical Research for the Twenty-first Century is the answer to that question. Drs. Greek explain briefly why one species cannot predict drug response for another and describe what research and testing methods should be used today instead of animals. They also describe where our biomedical research dollars should be spent if we are to have cures for cancer, AIDS, and Alzheimer's. This book will appeal to science-trained and general audiences, animal lovers and science readers, public policy analysts, students, patients and patient support groups, and government watchdog groups. What Will We Do If We Don't Experiment On Animals? Medical Research for the Twenty-first Century takes medical research out of the nineteenth and into the 21st century.

Book Description :

It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.

Book Description :

Improving and Accelerating Therapeutic Development for Nervous System Disorders is the summary of a workshop convened by the IOM Forum on Neuroscience and Nervous System Disorders to examine opportunities to accelerate early phases of drug development for nervous system drug discovery. Workshop participants discussed challenges in neuroscience research for enabling faster entry of potential treatments into first-in-human trials, explored how new and emerging tools and technologies may improve the efficiency of research, and considered mechanisms to facilitate a more effective and efficient development pipeline. There are several challenges to the current drug development pipeline for nervous system disorders. The fundamental etiology and pathophysiology of many nervous system disorders are unknown and the brain is inaccessible to study, making it difficult to develop accurate models. Patient heterogeneity is high, disease pathology can occur years to decades before becoming clinically apparent, and diagnostic and treatment biomarkers are lacking. In addition, the lack of validated targets, limitations related to the predictive validity of animal models - the extent to which the model predicts clinical efficacy - and regulatory barriers can also impede translation and drug development for nervous system disorders. Improving and Accelerating Therapeutic Development for Nervous System Disorders identifies avenues for moving directly from cellular models to human trials, minimizing the need for animal models to test efficacy, and discusses the potential benefits and risks of such an approach. This report is a timely discussion of opportunities to improve early drug development with a focus toward preclinical trials.

Book Description :

In this book, Dr. Li and his author team plan to emphasize why mouse models are useful in vivo systems for understanding disease mechanisms and developing therapeutic strategies in blood cancers. The authors do not intend to cover all types of blood cancers; instead, they will focus on some major ones such as leukemias and lymphomas. However, the authors will try to cover as much as they can the cancer types and point out that many blood cancers need to be studied in mouse disease models although they are still not available at present. A major focus in the book will be to show what we can or cannot learn from mouse disease models and to also show the critical contributions of mouse models in therapeutic drug development.

Book Description :

Retinal dystrophies are the major causes of incurable blindness in the Western world. Our insight into their aetiology has improved remarkably over the past decade and a number of key genes have been identified. Together with a more detailed understanding of disease processes, this knowledge is stimulating new approaches to therapeutic strategies involving gene therapy, growth factors and retinal cell transplantation. Molecular genetic studies have provided detailed information on the pathogenesis of retinal dystrophies. An important proof of principle that gene therapy holds great promise for the treatment of these conditions was demonstrated in the rds mouse: introduction of a functional copy of the peripherin gene subretinally resulted in complete rescue of rod outer segment structure. Novel approaches are being developed based on the manipulation of biochemical pathways that previously were not considered relevant to these diseases. For example, renewed interest in retinal dystrophy pathogenesis led to the successful use of high dose vitamin A treatment in Sorsby fundus dystrophy. This important new book covers all aspects of retinal dystrophies from the molecular and developmental biology of these disorders to possible therapeutic approaches, with special reference to gene therapy. Specific chapters deal with the molecular genetics of gene therapies, clinical genetic studies, molecular and cellular mechanisms of the development of the disease, functional genomics of retinal diseases, animal models of retinal dystrophies, and finally with studies on gene therapeutic approaches to correcting the disorder. With contributions by many of the leading researchers worldwide, this book is likely to be an important milestone in this rapidly developing field.
