Cet ouvrage reproduit les vingt-neuf chroniques parues de fin 1991 à 2002, accompagnées de commentaires qui les résultent dans leur contexte et examinent si, avec le recul, elles se révèlent ou non pertinentes.C'est donc un document qui fournit un éclairage sur ces dix années au cours desquelles la séquence de l'ADN humain, pur fantasme à usage politique au début, est devenue une réalité scientifique- sans pour antant, bien sûr, répondre à toutes les questions que pose la biologie.

How tiny variations in our personal DNA can determine how we look, how we behave, how we get sick, and how we get well.News stories report almost daily on the remarkable progress scientists are making in unraveling the genetic basis of disease and behavior. Meanwhile, new technologies are rapidly reducing the cost of reading someone's personal DNA (all six billion letters of it). Within the next ten years, hospitals may present parents with their newborn's complete DNA code along with her footprints and APGAR score. In Genetic Twists of Fate, distinguished geneticists Stanley Fields and Mark Johnston help us make sense of the genetic revolution that is upon us.Fields and Johnston tell real life stories that hinge on the inheritance of one tiny change rather than another in an individual's DNA: a mother wrongly accused of poisoning her young son when the true killer was a genetic disorder; the screen siren who could no longer remember her lines because of Alzheimer's disease; and the president who was treated with rat poison to prevent another heart attack. In an engaging and accessible style, Fields and Johnston explain what our personal DNA code is, how a few differences in its long list of DNA letters makes each of us unique, and how that code influences our appearance, our behavior, and our risk for such common diseases as diabetes or cancer.

The primary objective of this book is to provide the current status of and new data on the molecular mechanisms affecting the efficacy of somatic cell cloning, but also insightful interpretations of the topical and coming trends in the exploration of genomic, epigenomic, transcriptomic and proteomic profiles for nuclear donor cells, nuclear recipient oocytes and SCNT-derived embryos. Comprehensively deciphering the crucial molecular scenarios responsible for inter-genomic, inter-epigenomic, inter-transcriptomic and inter-proteomic communication within the framework of the aforementioned scenarios might be a milestone giving rise to the enhancements in the extra- and intracorporeal epigenetic reprogrammabilities of donor cell nuclei in nuclear-transferred oocytes, embryos, conceptuses and neonates. In turn, this might allow us to use SCNT-mediated ARTs in such research fields as biotechnology, transgenics, medicine, and biopharmacology, as well as scientific efforts targeted at designing the in vitro and in vivo models of molecular and epigenomic landscapes specific for inheritable and acquired disorders in humans and other mammalian species.

Embryo cleavage experiences a series of critical events and remarkable epigenetic modifications, especially morphological change and gene expression. The development of current assisted reproductive technology has created some new observations and novel discoveries in cleavage embryos. This book updates some new technologies and methods on the study of cleavage embryos to select high-quality embryos for transfer and improve embryo implantation and pregnancy. Major contents include embryo cleavage morphokinetics based on time-lapse imaging, gene expression of cleavage embryo and noninvasive assessment, and improving embryo cleavage technology. Thus, this book will greatly add new information for embryologists to select good-quality embryos for transfer to improve human embryo transfer pregnancy rate.

Matrix metalloproteinases (MMPs) are a family of proteolytic zinc-containing enzymes involved in physiological as well as in pathological processes in the human organism. MMPs play a key role in the remodeling of the extracellular matrix. Such a process may occur because of tissue homeostasis, morphogenesis, and tissue repair. However, remodeling could also be a part of many pathological states such as arthritis, cardiovascular diseases, neurodegenerative diseases, or impaired development in congenital anomalies. This book overviews the role of MMPs in different pathologies affecting the human body.

""Central dogma"" was presented by Dr. Francis Crick 60 years ago. The information of nucleotide sequences on DNAs is transcribed into RNAs by RNA polymerases. We learned the mechanisms of how transcription determines function of proteins and behaviour of cells and even how it brings appearances of organisms. This book is intended for scientists and medical researchers especially who are interested in the relationships between transcription and human diseases. This volume consists of an introductory chapter and 14 chapters, divided into 4 parts. Each chapter is written by experts in the basic scientific field. A collection of articles presented by active and laboratory-based investigators provides recent advances and progresses in the field of transcriptional regulation in mammalian cells.

Cytogenetics - Past, Present, and Further Perspectives discusses events that influenced the development of cytogenetics as a specialty within biology, with special attention paid to methodological achievements developed worldwide that have driven the field forward. Improvements to the resolution of chromosome analysis followed closely the introduction of innovative analytical technologies. In that sense, this book reviews and provides a brief account of the structure of chromosomes and stresses the high structural conservation in different species with an emphasis on aspects that require further research. However, it should be kept in mind that the future of cytogenetics will likely depend on improved knowledge of chromosome structure and function.

The new Genetic Diagnostics Act of July 31, 2009 raises important questions in the area of conflict between divergent perspectives, especially in the dialogue between human genetics and law. about the organization of the genetic counseling, the tasks of the newly created genetic diagnosis commission or regarding the prenatal genetic diagnosis. At the same time, the focus is on the classic medical law aspects of medical information and consent as well as data protection issues. This multifaceted spectrum of questions was the subject of a Göttingen workshop on medical law in November 2010, jointly organized by the Institute for Human Genetics (Faculty of Medicine) and the Center for Medical Law (Faculty of Law). The contributions and results of this conference are made available to the interested public in this volume.

Genetic transformation of plants has revolutionized both basic and applied plant research. Plant molecular biology and physiology benefit from this power fool, as well as biotechnology. This book is a review of some of the most significant achievements that plant transformation has brought to the fields of Agrobacterium biology, crop improvement and, flower, fruit and tree amelioration. Also, it examines their impact on molecular farming, phytoremediation and RNAi tools.
