Book Description
It can be argued that ATP is the most important molecule in cells. Not only is ATP the key energy source for cells, but it is also the source of phosphate groups that are transferred to a variety of substrate proteins via the action of elaborate families of protein kinases. An equally elaborate array of protein phosphatases can remove phosphate groups from proteins. It is now well established that protein phosphorylation is a widely used mechanism for cells to selectively modulate the function of a variety of proteins including enzymes, ion channels and pumps and structural proteins. In this volume of ACAG leading experts describe the evidence that protein phosphorylation is altered in aging and age-related disease. Protein phosphorylation controls fundamental processes such as transcription and translation, regulation of the cell cycle, signalling within and between cells, cell motility, synaptic function and so on. Recent findings are revealing how phosphorylation dependent signalling cascades may control lifespan with a prime example being the insulin-signalling pathway first described in c-elegans and now emerging as an important regulator of lifespan of mammals also. Many of the functional changes that occur during aging such as impaired learning and memory and altered energy metabolism are controlled by protein phosphorylation and it is, therefore, important to understand how mechanisms of protein phosphorylation may either mediate aging or provide adaptive responses that allow successful disease-free aging. The authors in addition to considering the roles of protein phosphorylation in aging describe the evidence that abnormalities in protein phosphorylation contribute to the pathogenesis of major age-related diseases including diabetes, atherosclerosis and neurodegenerative disorders such as Alzheimer's and Parkinson's diseases.

Book Description
Proper folding of proteins is crucial for cell function. Chaperones and enzymes that post-translationally modify newly synthesized proteins help ensure that proteins fold correctly, and the unfolded protein response functions as a homeostatic mechanism that removes misfolded proteins when cells are stressed. This book covers the entire spectrum of proteostasis in healthy cells and the diseases that result when control of protein production, protein folding, and protein degradation goes awry.

Book Description
This book provides the first comprehensive overview of a new scientific discipline termed Geroscience. Geroscience examines the molecular and cellular mechanisms that might explain why aging is the main risk factor for most chronic diseases affecting the elderly population. Over the past few decades, researchers have made impressive progress in understanding the genetics, biology and physiology of aging. This book presents vital research that can help readers to better understand how aging is a critical malleable risk factor in most chronic diseases, which, in turn, could lead to interventions that can help increase a healthy lifespan, or ‘healthspan.’ The book begins with an analysis of the Geroscience hypothesis, as well as the epidemiological underpinnings that define aging as a candidate main risk factor for most chronic diseases. Next, each chapter focuses on one particular disease, or group of diseases, with an emphasis on how basic molecular and cellular biology might explain why aging is a major risk factor for it. Coverage in the book includes: cancer, cardiovascular disease, dementias, stroke, Parkinson's and Alzheimer’s diseases, osteoporosis, arthritis, diabetes asthma, emphysema, kidney disease, vision impairment, and AIDS/HIV. It finishes with a chapter on pain in the elderly and an overview of future steps needed to bring the newly acquired knowledge into the clinic and the public at large.

Book Description
Cyclin Dependent Kinase 5 provides a comprehensive and up-to-date collection of reviews on the discovery, signaling mechanisms and functions of Cdk5, as well as the potential implication of Cdk5 in the treatment of neurodegenerative diseases. Since the identification of this unique member of the Cdk family, Cdk5 has emerged as one of the most important signal transduction mediators in the development, maintenance and fine-tuning of neuronal functions and networking. Further studies have revealed that Cdk5 is also associated with the regulation of neuronal survival during both developmental stages and in neurodegenerative diseases. These observations indicate that precise control of Cdk5 is essential for the regulation of neuronal survival. The pivotal role Cdk5 appears to play in both the regulation of neuronal survival and synaptic functions thus raises the interesting possibility that Cdk5 inhibitors may serve as therapeutic treatment for a number of neurodegenerative diseases.

Book Description
Proteins are amazingly versatile molecules. They make the chemical reactions happen that form the basis for life, they transmit signals in the body, they identify and kill foreign invaders, they form the engines that make us move, and they record visual images. All of this is now common knowledge, but it was not so a hundred years ago. Nature's Robots is an authoritative history of protein science, from the origins of protein research in the nineteenth century, when the chemical constitution of 'protein' was first studied and heatedly debated and when there was as yet no glimmer of the functional potential of substances in the 'protein' category, to the determination of the first structures of individual proteins at atomic resolution - when positions of individual atoms were first specified exactly and bonding between neighbouring atoms precisely defined. Tanford and Reynolds, who themselves made major contributions to the golden age of protein science, have written a remarkably vivid account of this history. It is a fascinating story, involving heroes from the past, working mostly alone or in small groups, usually with little support from formal research groups. It is also a story that embraces a number of historically important scientific controversies. Written in clear and accessible prose, Nature's Robots will appeal to general readers with an interest in popular science, in addition to professional scientists and historians of science.

Book Description
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.

Book Description
Humanity is aging. In the last century, life expectancy has increased by as much as 25 years, the greatest increase in 5'000 years of history. As a consequence the elderly constitute today the fastest growing segment of the world's population. This new situation creates many social problems and challenges to health care which both the developed as well as the developing countries will have to cope with. The present publication shows that scientific progress has reached a level where nutritional interventions may play a decisive part in the prevention of degenerative conditions of age, improvement of quality of life and impact on health care burden and resources. Topics deal with such different aspects as the influence of prenatal and early infant nutrition on the future aged individual and effects of energetic restriction on longevity. Further contributions include studies on mitochondrial alterations, digestive problems, specific metabolic deviations mediated by insulin, bone degradation, structural changes, neuromuscular dysfunctions, mental state of the elderly as well as the response of the immune system to nutrient intake. Finally the book offers a review of requirements appropriate to meet the age-related public health challenges of the 21st century.
