Available in PDF, EPUB and Kindle. Book excerpt: Popular understanding holds that genetic changes create cancer. James DeGregori uses evolutionary principles to propose a new way of thinking about cancerÕs occurrence. Cancer is as much a disease of evolution as it is of mutation, one in which mutated cells outcompete healthy cells in the ecosystem of the bodyÕs tissues. His theory ties cancerÕs progression, or lack thereof, to evolved strategies to maximize reproductive success. Through natural selection, humans evolved genetic programs to maintain bodily health for as long as necessary to increase the odds of passing on our genesÑbut not much longer. These mechanisms engender a tissue environment that favors normal stem cells over precancerous ones. Healthy tissues thwart cancer cellsÕ ability to outcompete their precancerous rivals. But as our tissues age or accumulate damage from exposures such as smoking, normal stem cells find themselves less optimized to their ecosystem. Cancer-causing mutations can now help cells adapt to these altered tissue environments, and thus outcompete normal cells. Just as changes in a speciesÕ habitat favor the evolution of new species, changes in tissue environments favor the growth of cancerous cells. DeGregoriÕs perspective goes far in explaining who gets cancer, when it appears, and why. While we cannot avoid mutations, it may be possible to sustain our tissuesÕ natural and effective system of defense, even in the face of aging or harmful exposures. For those interested in learning how cancers arise within the human body, the insights in Adaptive Oncogenesis offer a compelling perspective.

Download or read book The Oxford Handbook of Evolutionary Medicine written by Martin Brüne and published by Oxford University Press. This book was released on 2019-01-31 with total page 992 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medicine is grounded in the natural sciences, among which biology stands out with regard to the understanding of human physiology and conditions that cause dysfunction. Ironically though, evolutionary biology is a relatively disregarded field. One reason for this omission is that evolution is deemed a slow process. Indeed, macroanatomical features of our species have changed very little in the last 300,000 years. A more detailed look, however, reveals that novel ecological contingencies, partly in relation to cultural evolution, have brought about subtle changes pertaining to metabolism and immunology, including adaptations to dietary innovations, as well as adaptations to the exposure to novel pathogens. Rapid pathogen evolution and evolution of cancer cells cause major problems for the immune system to find adequate responses. In addition, many adaptations to past ecologies have turned into risk factors for somatic disease and psychological disorder in our modern worlds (i.e. mismatch), among which epidemics of autoimmune diseases, cardiovascular diseases, diabetes and obesity, as well as several forms of cancer stand out. In addition, depression, anxiety and other psychiatric conditions add to the list. The Oxford Handbook of Evolutionary Medicine is a compilation of cutting edge insights into the evolutionary history of ourselves as a species, and how and why our evolved design may convey vulnerability to disease. Written in a classic textbook style emphasising physiology and pathophysiology of all major organ systems, the Oxford Handbook of Evolutionary Medicine will be valuable for students as well as scholars in the fields of medicine, biology, anthropology and psychology.
Download or read book Advances in Stem Cell Aging written by K.L. Rudolph and published by Karger Medical and Scientific Publishers. This book was released on 2012-09-27 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adult stem cells are present in most postnatal tissues of mammals. Tissues with high rates of cell turnover depend on the functional capacity of stem cells for lifelong maintenance of tissue homeostasis. Adult stem cells are also required for the regeneration of tissues in response to injury as in, for example, the regeneration of skeletal muscle. In addition to its function in tissue homeostasis and regeneration, adult stem cells can represent the cell type of origin of various types of cancers including leukemia and colorectal cancer. Stem cells are the most long-lived cells in the proliferative compartment of mammalian tissues. Therefore, stem cells have an increased risk of acquiring mutations that could ultimately lead to the transformation of tissue stem cells.This publication presents the current knowledge in the field of stem cell aging, which was discussed at the Else Kröner-Fresenius Symposium on Advances in Stem Cell Aging in 2011. It will be of special interest to scientists working on stem cell research, aging, regeneration, and cancer as well as physicians and scientists specializing in geriatric medicine, internal medicine, and surgery.
Download or read book Darwin s Reach written by Norman A. Johnson and published by CRC Press. This book was released on 2021-12-27 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of evolutionary biology addresses a wide range of practical problems in medicine, agriculture, the environment, and society. Such cutting-edge applications are emerging due to recent advances in DNA sequencing, new gene editing tools, and computational methods. This book is about applied evolution – the application of the principles of and information about evolutionary biology to diverse practical matters. Although applied evolution has existed, unrecognized, for a very long time, today’s version has a much wider scope. Evolutionary medicine has formed into its own discipline. Evolutionary approaches have long been employed in agriculture and in conservation biology. But Darwin’s reach now extends beyond just these three fields. It now also includes forensic biology and the law. Ideas from evolutionary biology can be used to inform policy regarding foreign affairs and national security. Applied evolution is not only interdisciplinary, but also multidisciplinary. Consequently, this book is for experts in one field who are interested in expanding their evolutionary horizons. It is also for students, at the undergraduate and graduate levels. One of the public relations challenges faced by evolutionary biology is that most people do not see it being all that relevant to their daily lives. Even many who accept evolution do not grasp how far Darwin’s reach extends. This book will change that perception. Key Features Emphasizes the expanding role evolutionary biology has in today’s world. Includes examples from medicine, law, agriculture, conservation, and even national security Summarizes new technologies and computational methods that originated as innovations based in part or whole on evolutionary theory. Current. Has extensive coverage of the COVID-19 pandemic and other recent topics. Documents the important role evolution plays in everyday life. Illustrates the broadly interdisciplinary nature of evolutionary theory. Resources The applications of evolutionary biology are far too numerous to include in just one book. Plus, new scientific findings emerge almost every day underscoring the central role evolution plays in our lives. The author has established a blog site to highlight these fascinating discoveries. Please visit https://darwinsreach.blog to be inspired by “... endless forms most beautiful and most wonderful [that] have been, and are being evolved.” (the last line of Charles Darwin’s The Origin of Species).

Download or read book How Tobacco Smoke Causes Disease written by and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
Download or read book Stem Cell Aging Mechanisms Consequences Rejuvenation written by Hartmut Geiger and published by Springer. This book was released on 2015-07-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging of somatic stem cells reduces cell function and results in dysfunctional organs and tissues, making it an underlying cause of diseases associated with aging. It might even be the primary cause for age-associated attrition of tissue function in organs that heavily rely on stem cells for maintaining homeostasis, like the skin, blood and intestines. Understanding the molecular and cellular mechanisms involved is critical for developing approaches to attenuate stem cell aging and could pave the way for improved quality of life among the elderly. Written by highly prominent experts in the field, this book presents the current state of knowledge on these mechanisms. It offers insights into stem cell function, explains in detail the mechanisms of stem cell aging in model organisms as well as mammalian systems and describes related diseases and approaches to attenuating stem cell aging or achieving rejuvenation. The book is intended for all scientists and clinicians working with stem cells, aging mechanisms or age-related diseases.
Download or read book RNA DNA and Cancer written by Joseph G. Sinkovics and published by Springer. This book was released on 2016-04-01 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the author Joseph G. Sinkovics liberally shares his views on the cancer cell which he has been observing in vivo and in vitro, over a life time. Readers will learn how, as an inherent faculty of the RNA/DNA complex, the primordial cell survival pathways are endogenously reactivated in an amplified or constitutive manner in the multicellular host, and are either masquerading as self-elements or as placentas, to which the multicellular host is evolutionarily trained to extend full support. The host obliges. The author explains that there is no such evidence that “malignantly transformed” human cells survive in nature. However, when cared for in the laboratory, these cells live and replicate as immortalized cultures. These cells retain their vitality upon storage in liquid nitrogen. One can only imagine an astrophysical environment in which such cells could survive; perhaps, first their seemingly humble exosomes would populate that environment. Immortal cell populations so created may survive as individuals, or may even re-organize themselves into multicellular colonies, as representatives of life for the duration of the Universe. This thought-provoking book is the work of a disciplined investigator and clinician with an impeccable reputation, and he enters a territory that very few if any before him have approached from the same angles. It will appeal to researchers with an interest in cell survival pathways and those researching cancer cells.
Download or read book Rebel Cell written by Kat Arney and published by BenBella Books. This book was released on 2020-10-20 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do we get cancer? Is it our modern diets and unhealthy habits? Chemicals in the environment? An unwelcome genetic inheritance? Or is it just bad luck? The answer is all of these and none of them. We get cancer because we can't avoid it—it's a bug in the system of life itself. Cancer exists in nearly every animal and has afflicted humans as long as our species has walked the earth. In Rebel Cell: Cancer, Evolution, and the New Science of Life's Oldest Betrayal, Kat Arney reveals the secrets of our most formidable medical enemy, most notably the fact that it isn't so much a foreign invader as a double agent: cancer is hardwired into the fundamental processes of life. New evidence shows that this disease is the result of the same evolutionary changes that allowed us to thrive. Evolution helped us outsmart our environment, and it helps cancer outsmart its environment as well—alas, that environment is us. Explaining why "everything we know about cancer is wrong," Arney, a geneticist and award-winning science writer, guides readers with her trademark wit and clarity through the latest research into the cellular mavericks that rebel against the rigid biological "society" of the body and make a leap towards anarchy. We need to be a lot smarter to defeat such a wily foe—smarter even than Darwin himself. In this new world, where we know that every cancer is unique and can evolve its way out of trouble, the old models of treatment have reached their limits. But we are starting to decipher cancer's secret evolutionary playbook, mapping the landscapes in which these rogue cells survive, thrive, or die, and using this knowledge to predict and confound cancer's next move. Rebel Cell is a story about life and death, hope and hubris, nature and nurture. It's about a new way of thinking about what this disease really is and the role it plays in human life. Above all, it's a story about where cancer came from, where it's going, and how we can stop it.

Download or read book The Evolutionary Synthesis written by Ernst Mayr and published by Harvard University Press. This book was released on 1998 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology was forged into a single, coherent science only within living memory. In this volume the thinkers responsible for the "modern synthesis" of evolutionary biology and genetics come together to analyze that remarkable event. In a new Preface, Ernst Mayr calls attention to the fact that scientists in different biological disciplines varied considerably in their degree of acceptance of Darwin's theories. Mayr shows us that these differences were played out in four separate periods: 1859 to 1899, 1900 to 1915, 1916 to 1936, and 1937 to 1947. He thus enables us to understand fully why the synthesis was necessary and why Darwin's original theory--that evolutionary change is due to the combination of variation and selection--is as solid at the end of the twentieth century as it was in 1859.
Download or read book Ecology and Evolution of Cancer written by Beata Ujvari and published by Academic Press. This book was released on 2017-02-08 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology and Evolution of Cancer is a timely work outlining ideas that not only represent a substantial and original contribution to the fields of evolution, ecology, and cancer, but also goes beyond by connecting the interfaces of these disciplines. This work engages the expertise of a multidisciplinary research team to collate and review the latest knowledge and developments in this exciting research field. The evolutionary perspective of cancer has gained significant international recognition and interest, which is fully understandable given that somatic cellular selection and evolution are elegant explanations for carcinogenesis. Cancer is now generally accepted to be an evolutionary and ecological process with complex interactions between tumor cells and their environment sharing many similarities with organismal evolution. As a critical contribution to this field of research the book is important and relevant for the applications of evolutionary biology to understand the origin of cancers, to control neoplastic progression, and to prevent therapeutic failures. Covers all aspects of the evolution of cancer, appealing to researchers seeking to understand its origins and effects of treatments on its progression, as well as to lecturers in evolutionary medicine Functions as both an introduction to cancer and evolution and a review of the current research on this burgeoning, exciting field, presented by an international group of leading editors and contributors Improves understanding of the origin and the evolution of cancer, aiding efforts to determine how this disease interferes with biotic interactions that govern ecosystems Highlights research that intends to apply evolutionary principles to help predict emergence and metastatic progression with the aim of improving therapies
