The Telomere Effect


Book Description

The New York Times bestselling book coauthored by the Nobel Prize winner who discovered telomerase and telomeres' role in the aging process and the health psychologist who has done original research into how specific lifestyle and psychological habits can protect telomeres, slowing disease and improving life. Have you wondered why some sixty-year-olds look and feel like forty-year-olds and why some forty-year-olds look and feel like sixty-year-olds? While many factors contribute to aging and illness, Dr. Elizabeth Blackburn discovered a biological indicator called telomerase, the enzyme that replenishes telomeres, which protect our genetic heritage. Dr. Blackburn and Dr. Elissa Epel's research shows that the length and health of one's telomeres are a biological underpinning of the long-hypothesized mind-body connection. They and other scientists have found that changes we can make to our daily habits can protect our telomeres and increase our health spans (the number of years we remain healthy, active, and disease-free). The Telemere Effect reveals how Blackburn and Epel's findings, together with research from colleagues around the world, cumulatively show that sleep quality, exercise, aspects of diet, and even certain chemicals profoundly affect our telomeres, and that chronic stress, negative thoughts, strained relationships, and even the wrong neighborhoods can eat away at them. Drawing from this scientific body of knowledge, they share lists of foods and suggest amounts and types of exercise that are healthy for our telomeres, mind tricks you can use to protect yourself from stress, and information about how to protect your children against developing shorter telomeres, from pregnancy through adolescence. And they describe how we can improve our health spans at the community level, with neighborhoods characterized by trust, green spaces, and safe streets. The Telemere Effect will make you reassess how you live your life on a day-to-day basis. It is the first book to explain how we age at a cellular level and how we can make simple changes to keep our chromosomes and cells healthy, allowing us to stay disease-free longer and live more vital and meaningful lives.




Telomeres and Telomerase


Book Description

Telomeres are essential functional elements of eukaryotic chromosomes. Their fundamental biological role as protectors of chromosome stability was identified for the first time in the 1930s by Hermann Muller and Barbara McClintock based on pioneering cytological experiments. Modern molecular research carried out more recently revealed that telomeres and telomerase play important roles in processes such as carcinogenesis and cellular senescence. This special issue presents the most recent developments in this highly active field of research. It is becoming increasingly clear that molecular pathways involved in regulation of telomere length and structure are functionally linked with pathways involved in DNA damage response, cellular stress response, chromatin organization and perhaps even pathways that regulate evolutionary chromosome rearrangements. The above functional link is explored by the leading experts in the field of telomere biology. Cell biologists, molecular biologists, oncologists, gerontologists, and radiobiologists with an interest in the role of telomeres/telomerase will appreciate the up-to-date information in this publication.




Telomeres and Telomerase in Cancer


Book Description

Telomerase, an enzyme that maintains telomeres and endows eukaryotic cells with immortality, was first discovered in tetrahymena in 1985. In 1990s, it was proven that this enzyme also plays a key role in the infinite proliferation of human cancer cells. Now telomere and telomerase are widely accepted as important factors involved in cancer biology, and as promising diagnostic tools and therapeutic targets. Recently, role of telomerase in “cancer stem cells” has become another attractive story. Until now, there are several good books on telomere and telomerase focusing on biology in ciliates, yeasts, and mouse or basic sciences in human, providing basic scientists or students with updated knowledge.




Telomere Miracle


Book Description

What if everything you think you know about getting older and staying healthy is wrong? Ed Park, M.D., offers the revolutionary idea that disease and aging in humans all arises from a single source: genetic errors caused by shortening of telomeres, or the sequences of DNA at the ends of our chromosomes. Telomeres naturally wear down over time, and thus when cells replicate (as they do all the time in our bodies), they’re creating progressively poorer-quality duplicates of themselves, like making a Xerox of a Xerox of a Xerox. Ultimately, the body deteriorates, resulting in a range of ailments, many of which we associate with aging—from diabetes to hypertension to macular degeneration to cancer. Happily, Ed tells us, it’s possible to slow or even reverse this process and effectively turn back the clock. In The Telomere Miracle, he explains cutting-edge science in a lively style, using illustrations and metaphors ranging from auto parts to superheroes. Then he shows readers how they can intervene in the aging process by boosting the activity of the enzyme telomerase naturally by understanding and optimizing six key areas of breathing, mindset, sleep, exercise, diet, and supplements.




Telomere Diet & Cookbook


Book Description

A delicious way to hack your DNA and prevent early agingWhile some enjoy extremely active and healthy lives as they age, others spend years of their life burdened by heart disease, dementia, and other age-related diseases. Until recently, this was often chalked up to luck or “good genes.” But fascinating new research suggests that telomeres, the protective caps on your chromosomes, are actually directly linked to aging. Telomeres, when protected, can lead to a longer, happier life.Fortunately, one of the key components to protecting your telomeres is a balanced diet. The Telomere Diet and Cookbook is the first book to offer an easy-to-read, targeted overview of telomeres and nutrition. Including detailed meal plans and shopping lists, this book offers a simple step-by-step starter program and over 75 delicious recipes.




Telomeres, Diet and Human Disease


Book Description

The maintenance of telomeres—repetitive sequences at the end of chromosome—is essential to health. Dysfunction in telomere maintenance pathways plays a role in aging, cancer, atherosclerosis and other diseases. This has led to telomere maintenance as a prime target for patient therapies. This book describes the advances in telomere research as it applies to human health and especially how lifestyle and dietary factors could modify the telomerase maintenance process. The book examines the mechanisms involved, the primary of which are oxidative stress and the role of sirtuins, and how they can be modified by dietary patterns such as Mediterranean diet.




Telomeres


Book Description

An up-to-date survey of the current exciting state of telomere biology. Telomeres – specialized structures found at the ends of chromosomes – are essential for maintaining the integrity of chromosomes and their faithful duplication during cell division. Chapters in this volume cover telomere structure and function in a range of organisms, focusing on how they are maintained, their roles in cell division and gene expression, and how deficiencies in these structures contribute to cancers and other diseases and even aging.




Telomeres and Telomerase


Book Description

Telomeres and Telomerase Chairman: Sydney Brenner, 1997 Telomeres are the protective genetic elements located at the ends of chromosomes and are essential for correct chromosomal structure and function. They are not fully replicated by the conventional DNA polymerase system because DNA synthesis occurs only in the 5' to 3' direction and requires an RNA primer for initiation. Consequently, cells require a special enzyme to maintain the telomeric ends of chromosomes during each round of replication. This enzyme, telomerase, is a ribonucleoprotein that extends chromosome ends by adding short stretches of nucleotide repeats using a portion of its integral RNA component as the template. Recently, much excitement has been generated by the suggestion that telomerase, or rather the absence of telomerase and the resultant loss of terminal DNA, is a cause of human ageing. The evidence for this is twofold: the telomeres of certain cells in culture shorten during their lifespan; and immortalization of cells is associated, at least in some cases, with the maintenance of telomeres and telomerase activity. The latter observation prompted the analysis of clinical samples from patients with cancer and the demonstration that, in contrast to normal somatic cells, malignant cells possess telomerase activity. This is a unique book. Not only does it contain the latest experimental results from an international group of experts, but it also includes critical examinations of the current evidence, and discussions that attempt to identify the central and underlying concepts of this rapidly expanding field.




Telomeres


Book Description

Telomeres are specialized DNA–protein structures that protect the ends of chromosomes to maintain their integrity. They are chromosome sentinels. This book, written by multiple authors, presents current knowledge and the most recent discoveries relating to telomeres. The first chapters describe telomere structures (DNA and proteins), organization, dynamics and replication in a range of organisms including ciliates, yeast and mammals. The following chapters cover mechanisms that maintain telomere length involving telomerase and Alternative Lengthening Telomeres (ALT) mechanisms. Interestingly, telomeres are transcribed into repetitive RNA called TERRA (Telomeric repeat-containing RNA), the state of the art regarding mammalian telomere transcripts is presented here. Two chapters are dedicated to the description of how telomere biology impacts the development of cancer and how their disfunctions induce telomeropathies (telomere biology disorders). Finally, the book ends with a chapter presenting telomere and telomerase targeting agents as potential anticancer agents, a promising therapeutic approach.




Elizabeth Blackburn and the Story of Telomeres


Book Description

The story of molecular biologist Elizabeth Blackburn and her groundbreaking research on telomeres and what it reveals about the resourceful opportunism that characterizes the best scientific thinking. Molecular biologist Elizabeth Blackburn—one of Time magazine's 100 “Most Influential People in the World” in 2007—made headlines in 2004 when she was dismissed from the President's Council on Bioethics after objecting to the council's call for a moratorium on stem cell research and protesting the suppression of relevant scientific evidence in its final report. But it is Blackburn's groundbreaking work on telomeric DNA, which launched the field of telomere research, that will have the more profound and long-lasting effect on science and society. In this compelling biography, Catherine Brady tells the story of Elizabeth Blackburn's life and work and the emergence of a new field of scientific research on the specialized ends of chromosomes and the enzyme, telomerase, that extends them. In the early stages of telomere research, telomerase, heralded as a potential cure for cancer and diseases related to aging, attracted the voracious interest of biotech companies. The surrounding hype succeeded in confusing the role of telemorase in extending the life of a cell with a mechanism that might extend the lifespan of an entire organism. In Brady's hands, Blackburn's story reveals much about the tension between pure and applied science, the politicking that makes research science such a competitive field, and the resourceful opportunism that characterizes the best scientific thinking. Brady describes the science accessibly and compellingly. She explores Blackburn's struggle to break down barriers in an elite, male-dominated profession, her role as a mentor to other women scientists (many of whom have made their mark in telomere research), and the collaborative nature of scientific work. This book gives us a vivid portrait of an exceptional woman and a new understanding of the combination of curiosity, imaginative speculation, and aesthetic delight that powers scientific discovery.
