Available in PDF, EPUB and Kindle. Book excerpt: The world population is rapidly aging—it is estimated that by 1950, around 17% of the population will be elderly. In this context, aging involves several physiological, psychological and highly complex social processes that vary from one person to another. For a long time, medical care for older adults has focused on treating chronic, age-related diseases and their associated consequences. Recently, biomedical research brings a novel point of view to develop more effective interventions by targeting the aging process itself rather than separate conditions. There is a growing number of reports indicating that aging is driven by several interconnected mechanisms and biological components referred to as the molecular pillars of aging. Interfering with these mechanisms could help to treat, prevent, and understand the development of age-related diseases and associated syndromes. This book provides a clinical perspective and general update on biomedical and genetic research in aging, moving from an update in the molecular pillars of aging to a perspective of the most recent pharmacological, clinical, and diagnostic applications using genomic approaches and techniques. While this book focuses on the specifics of genetics and genomics, it also adopts a clinical perspective of geroscience, which seeks to understand the genetic, molecular and cellular mechanisms that make aging an important risk factor and, sometimes, a determining factor in the diseases and common chronic conditions of older people. Additionally, Clinical Genetics and Genomics of Aging is a significant contribution to support aging research, as it shows that collaboration across disciplines is relevant to progress in the field. As more and more people benefit from increased longevity, clinician and researchers will be empowered by this knowledge to contribute to the progress of aging research.

Available in PDF, EPUB and Kindle. Book excerpt: The Genetics of Aging is divided into several sections in an attempt to provide a logical progression from the level of the genome to the realm of human genetics. The relationship between the genetic material and aging will be thoroughly explored in the initial chapters. These chapters discuss in depth the various theories that have been proposed for the mechanisms of aging at the molecular level and present data which either support or contradict these hypotheses. Subsequent chapters will deal with the genetics of aging in organisms ranging from paramecium to mammals. The largest section of this volume will be devoted to several important areas in human genetics: human genetic disorders which feature premature aging, the effect of human parental aging on the production of genetically abnor mal offspring, the genetics of human longevity, and a review of studies on aging human twins. Over the last few decades genetic technology has provided enormous insight into a number of disciplines. Therefore, in the last few chapters, several genetic approaches to the study of aging are discussed: somatic cell genetics, immunogenetics, and behavioral genetics. As the goal of this volume is to present a comprehensive examination of the genetics of aging, most chapters are oriented toward general review of their respective areas. It is my hope that this volume will encourage clinical, biological, and behavioral investigators to turn their attention to the genetic aspects of aging as well as to employ genetic technology to obtain further insight into aging processes.

Book excerpt: The release of the complete version of the human genome sequence in 2003 has paved the way for defining gene function and genetic background for phenotypic variation in humans and allowed us to study the aging process in a new light. This new volume results from that research and focuses on the genetic and epigenetic process of aging. While the interpretation of the genome data is still in its initial stages, this new volume looks at the evolving understanding of molecular mechanisms involved in cellular processes, gene function associated with complex traits, epigenetic components involve in gene control and the creation of hypothesis-free genome-wide approaches. Longevity Genes: A Blueprint for Aging explores the genetic and genomic elements that can maintain a long life such as DNA damage mechanisms, epigenetics and the way we can use this knowledge to generate customized treatments. It touches on some of the multidisciplinary approaches as well as genomic-wide association technology used to analyze complex traits. This book describes the hunt for genes affecting complex traits using a high throughput technology, with adequate consideration for the selection of an appropriate population, applications of statistical genetics and computational biology, and most importantly, considering phenotype-genotype association studies. Longevity Genes provides coverage of not only established aspects of genetics and aging, but also new approaches and perceptions in this important area of research.

Available in PDF, EPUB and Kindle. Book excerpt: A leading geneticist explores what promises to be one of the most transformative advances in health and medicine in history Almost every week, another exciting headline appears about new advances in the field of genetics. Genetic testing is experiencing the kind of exponential growth once seen with the birth of the Internet, while the plummeting cost of DNA sequencing makes it increasingly accessible for individuals and families. Steven Lipkin and Jon Luoma posit that today’s genomics is like the last century’s nuclear physics: a powerful tool for good if used correctly, but potentially dangerous nonetheless. DNA testing is likely the most exciting advance in a long time for treating serious disease, but sequencing errors, complex biology, and problems properly interpreting genetic data can also cause life-threatening misdiagnoses of patients with debilitating and fatal genetic diseases. DNA testing can also lead to unnecessary procedures and significantly higher health-care costs. And just around the corner is the ability to cure genetic diseases using powerful gene-editing technologies that are already being used in human embryo research. Welcome to the Age of Genomes! The Age of Genomes immerses readers in true stories of patients on the frontier of genomic medicine and explores both the transformative potential and risks of genetic technology. It will inform anxious parents increasingly bombarded by offers of costly new prenatal testing products, and demonstrate how genetic technology, when deployed properly, can significantly improve the lives of patients who have devastating neurological diseases, cancer, and other maladies. Dr. Lipkin explains the science in depth, but in terms a layperson can follow.

Available in PDF, EPUB and Kindle. Book excerpt: Aging is one of those subjects that many biologists feel is largely unknown. Therefore, they often feel comfortable offering extremely facile generalizations that are either unsupported or directly refuted in the experimental literature. Despite this unfortunate precedent, aging is a very broad phenomenon that calls out for integration beyond the mere collecting together of results from disparate laboratory organisms. With this in mind, Part One offers several different synthetic perspectives. The editors, Rose and Finch, provide a verbal synthesis of the field that deliberately attempts to look at aging from both sides, the evolutionary and the molecular. The articles by Charlesworth and Clark both provide population genetic perspectives on aging, the former more mathematical, the latter more experimental. Bell takes a completely different approach, arguing that aging may not be the result of evolutionary forces. Bell's model instead proposes that aging could arise from the progressive deterioration of chronic host pathogen interactions. This is the first detailed publication of this model. It marks something of a return to the type of aging theories that predominated in the 1950's and 1960's, theories like the somatic mutation and error catastrophe theories. We hope that the reader will be interested by the contrast in views between the articles based on evolutionary theory and that of Bell. MR. Rose and C. E.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The molecular genetics of aging or life-span determination is an expanding field. One reason is because many people would consider it desirable if hu man life span could be extended. Indeed, it is difficult not to be fascinated by tales of the life and death of people who have succeeded in living a very long life. Because of this, we have placed at the head of this book the chapter by Perls et al. on Centenerians and the Genetics of Longevity. Perls and his coauthors convincingly argue that, while the average life expectancy might be mostly determined by environmental factors because the average person has an average genotype, extremely long life spans are genetically determined. Of course, studying humans to uncover the genetics of aging is not ideal, not so much because one cannot easily perform experiments as because they live such a long time. This is why most of this book describes the current state of research with model organisms such as yeast, worms, flies, and mice. J aswinski focuses on yeast and how metabolic activity and stress resistance affect the longevity of Saccharomyces cerevisiae. In the process, he discusses the concept of aging as applied to a unicellular organism such as yeast and the importance of metabolism and stress resistance for aging in all organisms.

Available in PDF, EPUB and Kindle. Book excerpt: This book is something which almost accidentally has developed very differently from how it was initially planned. The intention was to elaborate the part played by the immune system in ageing with the role of the thymus as central theme. It was to be essentially an expansion of a lecture I gave in 1970 and would inevitably have been concerned with much the same material as Walford's book, The Immunologic Theory of Aging, though from a different slant. What changed its character arose from a series of attempts to find logical connection between two findings that most gerontologists regard as axiomatic: that the lifespan of a mammal is genetically determined, and that the actual process of ageing is an accumulation of genetic error, of somatic mutations. It is possible that the connection is so indirect, circuitous and multiform that generations of detailed and unattractive research will be needed to elucidate it, or, more likely, the whole matter discarded as a non-problem. But a more inspiring approach does seem possible. The working hypothesis, which halfway through its writing became the new central theme of the book, arose when I was a member of a committee appointed by the Australian Academy of Science at the request of the Australian Government to advise on the danger from French nuclear tests in the South Pacific.
