This book covers a topic that has been neglected for years and has returned to the spotlight only recently. Until the genetic role of DNA was firmly established, many researchers suspected that proteins, rather than nucleic acids, could be carriers of heritable information. However, these models were completely forgotten with the triumphal march of the double helix and the development of a central dogma postulating that information flow occurs strictly from DNA, through RNA, to protein, making it seemingly impossible for the proteins to possess a coding potential. Proteins were downgraded to the role of simple perpetuators and executors of DNA orders. Taken together, data included in this book prove beyond a reasonable doubt that proteins and multiprotein complexes are able to control heritable traits, and that, at least in some examples, this control occurs in a template-like fashion, so that new structures strictly reproduce patterns of pre-existing structures that were not specifically coded in DNA. Thus, protein-based inheritance has left the area of speculation and has emerged as a new topic amenable to high-quality experimental analysis.

Many inheritable changes in gene function are not explained by changes in the DNA sequence. Such epigenetic mechanisms are known to influence gene function in most complex organisms and include effects such as transposon function, chromosome imprinting, yeast mating type switching and telomeric silencing. In recent years, epigenetic effects have become a major focus of research activity. This monograph, edited by three well-known biologists from different specialties, is the first to review and synthesize what is known about these effects across all species, particularly from a molecular perspective, and will be of interest to everyone in the fields of molecular biology and genetics.

It has been recognized for almost 200 years that certain families seem to inherit cancer. It is only in the past decade, however, that molecular genetics and epidemiology have combined to define the role of inheritance in cancer more clearly, and to identify some of the genes involved. The causative genes can be tracked through cancer-prone families via genetic linkage and positional cloning. Several of the genes discovered have subsequently been proved to play critical roles in normal growth and development. There are also implications for the families themselves in terms of genetic testing with its attendant dilemmas, if it is not clear that useful action will result. The chapters in The Genetics of Cancer illustrate what has already been achieved and take a critical look at the future directions of this research and its potential clinical applications.

This book examines the toxicological and health implications of environmental epigenetics and provides knowledge through an interdisciplinary approach. Included in this volume are chapters outlining various environmental risk factors such as phthalates and dietary components, life states such as pregnancy and ageing, hormonal and metabolic considerations and specific disease risks such as cancer cardiovascular diseases and other non-communicable diseases. Environmental Epigenetics imparts integrative knowledge of the science of epigenetics and the issues raised in environmental epidemiology. This book is intended to serve both as a reference compendium on environmental epigenetics for scientists in academia, industry and laboratories and as a textbook for graduate level environmental health courses.

Intrinsically Disordered Proteins: Dynamics, Binding, and Function thoroughly examines and ties together the fundamental biochemical functions of intrinsically disordered proteins (IDPs) and intrinsically disordered regions (IDRs), including signaling, binding, and regulation, with the methodology for study and the associated pathways for drug design and therapeutic intervention. The role of new mechanistic, computational, and experimental approaches in IDP study are explored in depth, with methods for the characterization of IDP dynamics; models, simulations, and mechanisms of IDP and IDR binding; and biological and medical implications of IDP dynamics prominently featured. Written and edited by leading scientists in the field, this book explores groundbreaking areas such as ensemble descriptions of IDPs and IDRs, single-molecule studies of IDPs and IDRs, IDPs and IDRs in membraneless organelles, and molecular mechanisms of fibrillation of IDPs. Intrinsically Disordered Proteins provides students and researchers in biochemistry, molecular biology, and applied microbiology with a comprehensive and updated discussion of the complex dynamics of IDPs and IDRs. - Provides in-depth discussion of fundamental IDP and IDR dynamics, function, and binding, with mechanistic insight to support new drug development - Describes the role of new computational and experimental approaches in characterizing the binding of IDPs to their functional targets - Features chapter contributions from international experts in IDP and IDR biochemical function and methods of study

Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. Nessa Carey, a leading epigenetics researcher, connects the field's arguments to such diverse phenomena as how ants and queen bees control their colonies; why tortoiseshell cats are always female; why some plants need cold weather before they can flower; and how our bodies age and develop disease. Reaching beyond biology, epigenetics now informs work on drug addiction, the long-term effects of famine, and the physical and psychological consequences of childhood trauma. Carey concludes with a discussion of the future directions for this research and its ability to improve human health and well-being.

Forty years ago, three medical researchers--Oswald Avery, Colin MacLeod, and Maclyn McCarty--made the discovery that DNA is the genetic material. With this finding was born the modern era of molecular biology and genetics.
