Download or read book Germline written by T. C. McCarthy and published by Orbit. This book was released on 2011-08-01 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Germline (n.) the genetic material contained in a cellular lineage which can be passed to the next generation. Also: secret military program to develop genetically engineered super-soldiers (slang). War is Oscar Wendell's ticket to greatness. A reporter for The Stars and Stripes, he has the only one way pass to the front lines of a brutal war over natural resources buried underneath the icy, mineral rich mountains of Kazakhstan. But war is nothing like he expected. Heavily armored soldiers battle genetically engineered troops hundreds of meters below the surface. The genetics-the germline soldiers-are the key to winning this war, but some inventions can't be un-done. Some technologies can't be put back in the box. Kaz will change everything, not least Oscar himself. Hooked on a dangerous cocktail of adrenaline and drugs, Oscar doesn't find the war, the war finds him.

Download or read book Maternal Control of Development in Vertebrates written by Florence Louise Marlow and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eggs of all animals contain mRNAs and proteins that are supplied to or deposited in the egg as it develops during oogenesis. These maternal gene products regulate all aspects of oocyte development, and an embryo fully relies on these maternal gene products for all aspects of its early development, including fertilization, transitions between meiotic and mitotic cell cycles, and activation of its own genome. Given the diverse processes required to produce a developmentally competent egg and embryo, it is not surprising that maternal gene products are not only essential for normal embryonic development but also for fertility. This review provides an overview of fundamental aspects of oocyte and early embryonic development and the interference and genetic approaches that have provided access to maternally regulated aspects of vertebrate development. Some of the pathways and molecules highlighted in this review, in particular, Bmps, Wnts, small GTPases, cytoskeletal components, and cell cycle regulators, are well known and are essential regulators of multiple aspects of animal development, including oogenesis, early embryogenesis, organogenesis, and reproductive fitness of the adult animal. Specific examples of developmental processes under maternal control and the essential proteins will be explored in each chapter, and where known conserved aspects or divergent roles for these maternal regulators of early vertebrate development will be discussed throughout this review.

Download or read book Heritable Human Genome Editing written by The Royal Society and published by National Academies Press. This book was released on 2021-01-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heritable human genome editing - making changes to the genetic material of eggs, sperm, or any cells that lead to their development, including the cells of early embryos, and establishing a pregnancy - raises not only scientific and medical considerations but also a host of ethical, moral, and societal issues. Human embryos whose genomes have been edited should not be used to create a pregnancy until it is established that precise genomic changes can be made reliably and without introducing undesired changes - criteria that have not yet been met, says Heritable Human Genome Editing. From an international commission of the U.S. National Academy of Medicine, U.S. National Academy of Sciences, and the U.K.'s Royal Society, the report considers potential benefits, harms, and uncertainties associated with genome editing technologies and defines a translational pathway from rigorous preclinical research to initial clinical uses, should a country decide to permit such uses. The report specifies stringent preclinical and clinical requirements for establishing safety and efficacy, and for undertaking long-term monitoring of outcomes. Extensive national and international dialogue is needed before any country decides whether to permit clinical use of this technology, according to the report, which identifies essential elements of national and international scientific governance and oversight.

Download or read book Human Genome Editing written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-08-13 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genome editing is a powerful new tool for making precise alterations to an organism's genetic material. Recent scientific advances have made genome editing more efficient, precise, and flexible than ever before. These advances have spurred an explosion of interest from around the globe in the possible ways in which genome editing can improve human health. The speed at which these technologies are being developed and applied has led many policymakers and stakeholders to express concern about whether appropriate systems are in place to govern these technologies and how and when the public should be engaged in these decisions. Human Genome Editing considers important questions about the human application of genome editing including: balancing potential benefits with unintended risks, governing the use of genome editing, incorporating societal values into clinical applications and policy decisions, and respecting the inevitable differences across nations and cultures that will shape how and whether to use these new technologies. This report proposes criteria for heritable germline editing, provides conclusions on the crucial need for public education and engagement, and presents 7 general principles for the governance of human genome editing.
Download or read book Genetics of Human Infertility written by P.H. Vogt and published by Karger Medical and Scientific Publishers. This book was released on 2017-09-12 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infertility affects more than one in ten couples worldwide and is related to highly heterogeneous pathologies sometimes only discernible in the germ line. Its complex etiology often, but not always, includes genetic factors besides anatomical defects, immunological interference, and environmental aspects. Nearly 30% of infertility cases are probably caused only by genetic defects. Thereby experimental animal knockout models convincingly show that infertility can be caused by single or multiple gene defects. Translating those basic research findings into clinical studies is challenging, leaving genetic causes for the vast majority of infertility patients unexplained. Nevertheless, a large number of candidate genes have been revealed by sophisticated molecular methods. This book provides a comprehensive overview on the subject of infertility written by the leading authorities in this field. It covers topics including basic biological, cytological, and molecular studies, as well as common and uncommon syndromes. It is a must-read for human geneticists, endocrinologists, epidemiologists, zoologists, and counsellors in human genetics, infertility, and assisted reproduction.

Download or read book How Does Germline Regenerate written by Kate MacCord and published by University of Chicago Press. This book was released on 2024-01-05 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: A concise primer that complicates a convenient truth in biology--the divide between germ and somatic cells--with far-reaching ethical and public policy ramifications. Scientists have long held that we two have kinds of cells--germ and soma. Make a change to germ cells--say using genome editing--and that change will appear in the cells of future generations. Somatic cells are "safe" after such tampering; modify your skin cells, and your future children's skin cells will never know. And, while germ cells can give rise to new generations (including all of the somatic cells in a body), somatic cells can never become germ cells. How did scientists discover this relationship and distinction between somatic and germ cells--the so-called Weismann Barrier--and does it actually exist? Can somatic cells become germ cells in the way germ cells become somatic cells? That is, can germ cells regenerate from somatic cells even though conventional wisdom denies this possibility? Covering research from the late nineteenth century to the 2020s, historian and philosopher of science Kate MacCord explores how scientists came to understand and accept the dubious concept of the Weismann Barrier and what profound implications this convenient assumption has for research and policy, from genome editing to stem cell research, and much more.
