The completion of a consensus draft sequence for the human genome was the starting point for more thorough investigations of individual genome variation. The development of array-based strategies made it possible to look at our genome in new ways and for new types of variation to be discovered and characterized. Characterization of copy number variation and other forms of structural genetic variation has highlighted the complexity of human genetic variation and also provided significant insight into the evolution and dynamic nature of our genome. Genomic Structural Variants: Methods and Protocols provides an in-depth description of the developments in our understanding of structural genetic variation and its implications for human disease, from the introduction of microarrays up to current state-of-the-art sequencing strategies. It covers the major technologies used for research and diagnostics as well as web-based resources for variation data, and it then goes into depth regarding specific regions of the genome that differ in variation content. Specific patient groups where copy number variation has been shown to be of great importance are highlighted, and implications for both pre-natal and standard diagnostics are described. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Genomic Structural Variants: Methods and Protocols provides complete comprehensive coverage of this burgeoning field.

The discovery of stress-induced mutagenesis has changed ideas about mutation and evolution, and revealed mutagenic programs that differ from standard spontaneous mutagenesis in rapidly proliferating cells. The stress-induced mutations occur during growth-limiting stress, and can include adaptive mutations that allow growth in the otherwise growth-limiting environment. The stress responses increase mutagenesis specifically when cells are maladapted to their environments, i.e. are stressed, potentially accelerating evolution then. The mutation mechanism also includes temporary suspension of post-synthesis mismatch repair, resembling mutagenesis characteristic of some cancers. Stress-induced mutation mechanisms may provide important models for genome instability underlying some cancers and genetic diseases, resistance to chemotherapeutic and antibiotic drugs, pathogenicity of microbes, and many other important evolutionary processes. This book covers pathways of stress-induced mutagenesis in all systems. The principle focus is mammalian systems, but much of what is known of these pathways comes from non-mammalian systems.

Pancreatic cancer is a formidable disease, and advances in early detection and improved therapeutics have been slow to come forth. With new advances in molecular genetics in the field of pancreatic tumorigenesis, it is an opportune time to use these recent discoveries to enhance our understanding of pancreatic cancer biology and to improve outcomes in patients. In this volume, leading experts in the field shed light on these findings describing the mutational landscape of pancreatic cancer, including new inroads into our understanding of familial pancreatic cancer, epidemiology, the biology of K-ras signaling, and the emerging contribution of epigenetic alterations to disease initiation and progression. The distinctive pancreatic cancer-stroma ecosystem as determined by the dynamic interplay of inflammation, hallmark mutations, EMT, and cancer stem cells is described, and implications of these interactions in the context of development of novel, personalized therapeutic options are explored.

The volume is collection of articles treating the topic of human improvement/enhancement from a variety of perspectives - philosophical, literary, medical, genetic, sociological, legal etc. The chapters in this volume treat not only those aspects that most immediately come to mind when one thinks of 'human enhancement', such as genetic engineering, cloning, artificial implants and artificial intelligence etc. Somewhat less obvious aspects include evolutionary perspectives in connection with the prolongation of the human lifespan, plastic surgery since its beginnings, and questions such as whether the distinction between 'natural' and 'artificial' can really be drawn at all and how it has been conceived across the ages, or what the legal implications are of recent developments and techniques. Many papers make links to the representation of these developments in popular culture, from Jules Verne through Aldous Huxley to the movie Gattaca, address the hopes and fears that come with them as well as the question how realistic these are. While all chapters are written by scientists at the international top of their respective fields, all are accessible to a non-specialist audience and eminently readable. We believe that they represent a state-of-the art overview of questions that are of interest to a large audience. The book thus targets a non-specialist audience with an interest in philosophical, sociological, scientific and legal issues involved in both traditional and recent matters concerning the desire of mankind to improve itself, the human body, the human mind and the human condition. It is unique in that it brings together all these aspects within a coherent and cohesive collection.

Primary immunodeficiency diseases (PIDs) are a heterogeneous group of inherited disorders characterized by different defects in the development and function of the immune system. This book aims to increase the clinical awareness and knowledge of practicing clinicians regarding the diagnosis and management of PIDs. In order to achieve this goal, about 90 cases drawn from real life are presented, along with approximately 300 related questions. The selected case reports are the result of the invaluable cooperation of more than 40 scientists in the field of immunodeficiency. They focus both on the presenting features of patients with PIDs and on the required further investigation and management. Each of the numbered cases is followed by the questions, their answers, and additional discussion. Each question focuses on a particular aspect of the PID under consideration, and the topics covered include clinical diagnosis, laboratory findings, molecular mechanisms, and therapy.

GW bodies are novel cytoplasmic foci that were discovered and named by Dr. Chan's group in 2002. These bodies are now known to be active cytoplasmic foci involved with the new gene regulation process mediated by microRNA that leads to translational repression and mRNA degradation. The detailed biological functions of these cytoplasmic structures are still being uncovered and the idea for this book is to provide the history of the discovery and the major work from different laboratories that has led to the characterization and elucidation of the structure and function of these new multiple subcellular structures.

The combination of molecular biology, engineering and bioinformatics has revolutionized our understanding of cancer revealing a tight correlation of the molecular characteristics of the primary tumor in terms of gene expression, structural alterations of the genome, epigenetics and mutations with its propensity to metastasize and to respond to therapy. It is not just one or a few genes, it is the complex alteration of the genome that determines cancer development and progression. Future management of cancer patients will therefore rely on thorough molecular analyses of each single case. Through this book, students, researchers and oncologists will obtain a comprehensive picture of what the first ten years of cancer genomics have revealed. Experts in the field describe, cancer by cancer, the progress made and its implications for diagnosis, prognosis and treatment of cancer. The deep impact on the clinics and the challenge for future translational research become evident.

Androgens and androgen receptors (AR) play critical roles in the development and progression of prostate cancer, the most frequently diagnosed cancer and second leading cause of cancer death in US males. AR is an androgen-dependent DNA-binding transcription factor that regulates the expression of androgen-responsive genes. Identification and characterization of androgen-responsive genes provide insights into the cellular mechanisms of androgen action and may lead to new approaches in diagnosis, prognosis, prevention and/or treatment of prostate cancer. This volume provides critical information from well respected experts in the field. Some of the exciting topics include the new understanding of mechanisms underlining the regulation of androgen-responsive gene expression, and functions of various androgen-responsive genes in biological processes essential in carcinogenesis including cell growth, angiogenesis, and epithelial-to-mesenchyme transition (EMT). Other important aspects addressed are the current and potential clinic applications of knowledge on androgen-responsive gene regulation and function. This book is intended for researchers, scientists, faculty, and advanced graduate students with an interest in androgen action and prostate cancer.

The volume provides a forum for original peer-reviewed short communications, full-length research and review articles on new research findings and developments on the topic of genetic targets on cancer therapies. As the field is highly important it requires co-operation between research communities from all over the world to share their knowledge and experience in order to move the field forward. Each chapter includes a discussion of the impact of the tumor microenvironment and cancer stem cells and cover current knowledge in this area as it pertains to the disease, including emerging therapy targeting the microenvironment and/or cancer stem cells.

The central question of this book is whether or not particular cell entities of human origin ought to be considered human beings. The answer is crucial for making moral decisions for or against research and experimentation. Experts in the field discuss the production of embryonic-like pluripotent stem cells by altered nuclear transfer, parthenogenesis and reprogramming of adult somatic cells. They thoroughly analyse the biological and moral status of different cell entities, such as human stem cells, embryos and human-animal hybrid embryos, and make a decisive step towards establishing final criteria for what constitutes a human being. The topic is challenging in nature and of broad interest to all those concerned with current bioethical thought on embryonic human life and its implications for society.

utoimmunity is the downstream outcome of a rather extensive and coordinated series of events that include loss of self-tolerance, peripheral lymphocyte Aactivation, disruption of the blood-systems barriers, cellular infiltration into the target organs and local inflammation. Cytokines, adhesion molecules, growth factors, antibodies, and other molecules induce and regulate critical cell functions that perpetuate inflammation, leading to tissue injury and clinical phenotype. The nature and intensity of this response as well as the physiological ability to restore homeostasis are to a large extent conditioned by the unique amino acid sequences that define allelic variants on each of the numerous participating mol ecules. Therefore, the coding genes in their germline configuration play a primary role in determining who is at risk for developing such disorders, how the disease progresses, and how someone responds to therapy. Although genetic components in these diseases are clearly present, the lack of obvious and homogeneous modes of transmission has slowed progress by prevent ing the full exploitation of classical genetic epidemiologic techniques. Furthermore, autoimmune diseases are characterized by modest disease risk heritability and m- tifaceted interactions with environmental influences. Yet, several recent discoveries have dramatically changed our ability to examine genetic variation as it relates to human disease. In addition to the development of large-scale laboratory methods and tools to efficiently recognize and catalog DNA diversity, over the past few years there has been real progress in the application of new analytical and data-manage ment approaches.

Circadian rhythms are such an innate part of our lives that we rarely pause to speculate why they even exist. Some studies have suggested that the disruption of the circadian system may be causal for obesity and manifestations of Metabolic Syndrome (MetS). Shift-work, sleep-deprivation and bright-light-exposure at night are related to increased adiposity (obesity) and prevalence of MetS. It has been provided evidence of clock genes expression in human adipose tissue and demonstrated its association with different components of the MetS. Moreover, current studies are illustrating the particular role of different clock genes variants and their predicted haplotypes in MetS. The purpose of "Chronobiology and Obesity" is to describe the mechanisms implicated in the interaction between chonodisruption and metabolic-related illnesses, such as obesity and MetS, with different approaches.

I entered the gene therapy field in the mid-1990s, being fascinated by the immense potential of genes as drugs for the treatment of human disease. Since then, I have experienced the ups and downs of this discipline, and tried to contribute with my work and that of my laboratory to the development of innovative approaches to the treatment of cardiovascular disorders. During these years, I have had several opp- tunities to speak on gene therapy at lectures and academic lessons, and have often noticed that the field is very attractive to scientists of all disciplines. However, as yet no comprehensive book on the subject has been published. Indeed, most books in the field are either a collection of gene transfer laboratory protocols or deal with the subject in a rather superficial manner. Hence the idea to write a gene therapy textbook that is broad and comprehensive, but at the same time provides sufficient molecular and clinical detail to be of interest to students, professors, and specialists in the various disciplines that contribute to gene therapy. I have tried to keep the language plain and, whenever possible, non-technical. Since the book is intended to be a textbook in the field of gene therapy in both the basic science and clinical areas, whenever technical descriptions are required, they are provided.

This book will provide latest insights in the functional potentials of ribonucleic acids in medine and the use of Spiegelmer and Spiegelzyme systems. It will also deal with a new type of delivery systems for cellular targeting.

JIMD Reports publishes case and short research reports in the area of inherited metabolic disorders. Case reports highlight some unusual or previously unrecorded feature relevant to the disorder, or serve as an important reminder of clinical or biochemical features of a Mendelian disorder.

With very few exceptions, eukaryotic cells possess two interdependent genomes, chromosomal and extra-chromosomal. Over the past several decades, cancer - search has focused primarily on deciphering the intricate alterations in the chro- somal genome, with until recently, very little attention to its cytoplasmic counterpart. In spite of the enormous complexity of the nuclear genome, which we now fully appreciate after completion of the human genome project, the efforts of cancer researchers are commendable in terms of the tremendous gains made in unraveling the numerous genetic changes in cancer. These changes include d- coveries of tumor suppressor genes, oncogenes, and caretaker genes that are often mutated in cancer. Recent studies of genomic pro?les are uncovering even more altered and mutated genes in cancer. Besides these ?ndings, several therapeutic targets for chemotherapy are currently made from studies of altered nuclear genetic pathways. Inspite of all these positive efforts, the war on cancer, declared in 1971 by Richard Nixon, is far from being worn. Indeed, the failure of chemotherapy is obvious to clinicians, oncologists, and their patients alike. Moreover, the global incidence and prevalence of cancer continue to rise. What are we missing? Which direction should we be taking? Of course, modern integrated nuclear genomics, proteomics, and metabolomics should provide important clues to carcinogenesis, but the contribution of cytoplasmic genetic alterations to carcinogenesis cannot be neglected.

This is the most comprehensive, up-to-date reference on this post-translational modification of proteins, which is intimately linked with DNA repair, maintenance of genomic stability, transcriptional regulation, cell death and a variety of other cellular phenomena as well as with a variety of pathophysiological conditions, including ischemia-reperfusion damage, Parkinson's disease, Type I diabetes mellitus, hemorrhagic and septic shock and other inflammatory conditions. Richly illustrated, it offers 19 chapters written by international experts.

As cells mature they naturally stop dividing and enter a period called senescence. But cellular senescence can also be induced prematurely by certain oncogenes involved in cancer development. Cellular senescence, a growth-arrest program that limits the lifespan of mammalian cells and prevents unlimited cell proliferation, is attracting considerable interest because of its links to tumor suppression.

Gene Expression and its Discontents examines a class of probability models describing how epigenetic context affects gene expression and organismal development, using the asymptotic limit theorems of information theory in a highly formal manner. Taking classic results on spontaneous symmetry breaking abducted from statistical physics in groupoid, rather than group, circumstances, the work suggests that epigenetic information sources act as analogs to a tunable catalyst, directing development into different characteristic pathways according to the structure of external signals. The results have significant implications for epigenetic epidemiology, in particular for understanding how environmental stressors, in a large sense, can induce a broad spectrum of developmental disorders in humans. The authors then apply the perspective to a number of chronic diseases broadly associated with obesity, using data at different scales of observation.

The CCN family of genes currently comprises six secreted proteins (designated CCN16 i.e., Cyr61/CCN1; ctgf/CCN2; Nov/CCN3; WISP1/CCN4; WISP2/CCN5, and WISP3/CCN6) showing a strikingly conserved primary structure, with four modules sharing partial identity with IGF binding proteins, Von Willebrand protein, thrombospondin and several matricellular proteins and growth factors. The current view is that CCN proteins modulate signaling pathways that involve regulatory components of the extracellular matrix. As such, they likely act as a central hub in the regulation of mitosis, adhesion, apoptosis, extracellular matrix production, growth arrest and migration of multiple cell types. The 5th international workshop on the CCN family of genes, that was held in Toronto in 2008 brought together scientists from around the world who have an interest in the biological roles of this emerging family of proteins. On an educational point of view, the workshop was a unique place for an efficient diffusion of scientific information. The present book comprises a series of selected manuscripts that are based on the original communications that were presented at the meeting by worldwide leaders in the field of CCN biology. All major aspects of CCN proteins biology in both normal and pathological conditions are covered in this volume, from structure-functions analysis up to the involvement of CCN proteins in complex physiological functions. In addition to reports that support the Yin-Yang concept of CCN proteins driving opposite effects on the same biological process, this book also comprises several contributions that point to CCN proteins as amenable targets for therapeutic manipulation of disease processes. Together with the special issue of Journal of Cell Communication and Signaling in which authors have extended on the original data presented at the meeting, the present Proceedings provide an instant picture and unique update of the state of the art in the CCN field.

Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer's disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.

In the last ten years there has been a considerable increase of interest on the notion of the minimal cell. With this term we usually mean a cell-like structure containing the minimal and sufficient number of components to be defined as alive, or at least capable of displaying some of the fundamental functions of a living cell. In fact, when we look at extant living cells we realize that thousands of molecules are organized spatially and functionally in order to realize what we call cellular life. This fact elicits the question whether such huge complexity is a necessary condition for life, or a simpler molecular system can also be defined as alive. Obviously, the concept of minimal cell encompasses entire families of cells, from totally synthetic cells, to semi-synthetic ones, to primitive cell models, to simple biomimetic cellular systems. Typically, in the experimental approach to the construction of minimal the main ingredient is the compartment. Lipid vesicles (liposomes) are used to host simple and complex molecular transformations, from single or multiple enzymic reactions, to polymerase chain reactions, to gene expression. Today this research is seen as part of the broader scenario of synthetic biology but it is rooted in origins of life studies, because the construction of a minimal cell might provide biophysical insights into the origins of primitive cells, and the emergence of life on earth. The volume provides an overview of physical, biochemical and functional studies on minimal cells, with emphasis to experimental approaches. 15 International experts report on their innovative contributions to the construction of minimal cells.

Identification of cancer risk factors and potential prevention strategies have been some of the most important medical and research contributions to the improvement of public health in the past half-century (Steele 2003). Und- standing the role of lifestyle, exposure to endogenous factors and exogenous environmental factors, and individual genetic and epigenetic variability have contributed significantly to this effort. Cancer prevention strategies have been developed based on results of epidemiologic, preclinical, and clinical studies that have generated clues for identifying risk factors that may be modulated by changes in lifestyle, such as smoking cessation or dietary modification (Greenwald 2002a). In addition, significant progress in medical interventions involving chemoprevention-a pharmacological approach to intervention that aims to prevent, arrest, or reverse either the initiation phase of carcinogenesis or the progression of premalignant cells-is beg- ning to pay dividends in reducing risks associated with cancer. Emerging technologies, identification of biomarkers of risk, and advances in genetics research also are finding applications in chemoprevention research that p- mise to speed the acquisition of knowledge on the molecular and cellular - fects of chemopreventive agents. 2 Lifestyle Approaches Population studies from the 1950s through the early 1980s provided c- pelling evidence that modifiable lifestyle choices can either increase or - crease cancer risk. For example, several landmark epidemiologic studies in the 1950s showed a clear association between smoking and lung cancer (Wynder and Graham 1950; Levin et al. 1950). In 1964, the U. S.

The use of molecular biology and biochemistry to study the regulation of gene expression has become a major feature of research in the biological sciences. Many excellent books and reviews exist that examine the experimental methodology employed in specific areas of molecular biology and regulation of gene expression. However, we have noticed a lack of books, especially textbooks, that provide an overview of the rationale and general experimental approaches used to examine chemically or disease-mediated alterations in gene expression in mammalian systems. For example, it has been difficult to find appropriate texts that examine specific experimental goals, such as proving that an increased level of mRNA for a given gene is attributable to an increase in transcription rates. Regulation of Gene Expression: Molecular Mechanisms is intended to serve as either a textbook for graduate students or as a basic reference for laboratory personnel. Indeed, we are using this book to teach a graduate-level class at The Pennsylvania State University. For more details about this class, please visit http://moltox. cas. psu. edu and select "Courses. " The goal for our work is to provide an overview of the various methods and approaches to characterize possible mechanisms of gene regulation. Further, we have attempted to provide a framework for students to develop an understanding of how to determine the various mechanisms that lead to altered activity of a specific protein within a cell.
