Candid, provocative, and disarming, this is the widely-praised memoir of the co-discoverer of the double helix of DNA.
'A phenomenally important book' Lewis Dartnell, author of Origins Why do we live in families? Why do we help complete strangers? Why do we compare ourselves to others? Why do we cooperate? The science of cooperation tells us not only how we got here, but also where we might end up. In The Social Instinct Nichola Raihani introduces us to other species who, like us, live and work together. From the pied babblers of the Kalahari to the cleaner fish of the Great Barrier Reef, they happen to be some of the most fascinating and extraordinarily successful species on this planet. What do we have in common with these animals, and what can we learn from them? The Social Instinct is an exhilarating, far-reaching and thought-provoking journey through all life on Earth, with profound insights into what makes us human and how our societies work. 'A pleasing juxtaposition of insightful scientific theory with illuminating anecdotes' Richard Dawkins 'Surprising, thoughtful and, best of all, endlessly entertaining' Will Storr, author of The Science of Storytelling 'A superb book about how important cooperation is' Alice Roberts, author of Ancestors
Genome sequencing is one of the most exciting scientific breakthroughs of the past thirty years. But what precisely does it involve and how is it developing? In this brilliantly wide-ranging, one-stop guide WIRED journalist Rachael Pells explains the science behind genomics. She analyses its practical applications in medical diagnosis and the treatment of conditions that range from cancer to severe allergic reactions to cystic fibrosis. She considers its potential to help with advances in agriculture and environmental science. She explores the ethics of genetic modification and the dangers involved when humans 'play God'. And she addresses the fundamental question: to what extent will future advances transform human longevity and the quality of life.
In Managing Health in the Genomic Era: A Guide to Family Health History and Disease Risk, Drs. Vincent C. Henrich, Lori A. Orlando, and Brian H. Shirts discuss the practical considerations surrounding the use of genomic and genetic tests to manage patient health, to provide adult disease risk assessment, to improve diagnosis, and to support effective interventions and treatment. In 10 chapters, evidence-based information and case studies are described and examine the central place of family health history (FHH) in genomic medicine, tools and strategies for compiling and analyzing family health history, how to identify existing and novel genetic markers, how to identify lineage specific (or rare) variants within families, and how to find effective interventions based on genetic testing results and FHH. Factors that influence clinical practice, including gene-environment interactions, FHH social networking, direct to consumer (DTC) genetic testing and data sharing, algorithms for analyzing genetic data, and patient counseling are discussed from the standpoint of clinical practice. Here, frontline healthcare providers will discover succinct commentary and key examples to assist with their local needs. Relevant principles of genetic biology and inheritance are explored and guidance on available support networks and online resources is also provided.
There have been remarkable advances towards discovering agents that exhibit selectivity and sequence-specificity for DNA, as well as understanding the interactions that underlie its propensity to bind molecules. This progress has important applications in many areas of biotechnology and medicine, notably in cancer treatment as well as in future gene targeting therapies. The editor and contributing authors are leaders in their fields and provide useful perspectives from diverse and interdisciplinary backgrounds on the current status of this broad area. The role played by chemistry is a unifying theme. Early chapters cover methodologies to evaluate DNA-interactive agents and then the book provides examples of DNA-interactive molecules and technologies in development as therapeutic agents. DNA-binding metal complexes, peptide and polyamide–DNA interactions, and gene targeting tools are some of the most compelling topics treated in depth. This book will be a valuable resource for postgraduate students and researchers in chemical biology, biochemistry, structural biology and medicinal fields. It will also be of interest to supramolecular chemists and biophysicists.
Epigenetics is the study of heritable changes in gene function that do not involve changes in the DNA sequence. These changes, consisting principally of DNA methylation, histone modifications, and non-coding RNAs, maintain or modulate the initial impact of regulatory factors that recognize and associate with particular genomic sequences. Epigenetic modifications are manifest in all aspects of normal cellular differentiation and function, but they can also have damaging effects that result in pathologies such as cancer. Research is continuously uncovering the role of epigenetics in a variety of human disorders, providing new avenues for therapeutic interventions and advances in regenerative medicine. This book's primary goal is to establish a framework that can be used to understand the basis of epigenetic regulation and to appreciate both its derivation from genetics and interdependence with genetic mechanisms. A further aim is to highlight the role played by the three-dimensional organization of the genetic material itself (the complex of DNA, histones and non-histone proteins referred to as chromatin), and its distribution within a functionally compartmentalized nucleus. This architectural organization of the genome plays a major role in the subsequent retrieval, interpretation, and execution of both genetic and epigenetic information.
Growing evidence suggests that epigenetic mechanisms play a central role in stem cell biology and are vital for determining gene expression during cellular differentiation and governing mammalian development. In Stem Cell Epigenetics, leading international researchers examine how chromatin regulation and bona fide epigenetic mechanisms underlie stem cell renewal and differentiation. Authors also explore how the diversity of cell types, including the extent revealed by single cell omic approaches, is achieved, and how such processes may be reversed or managed via epigenetic reprogramming. Topics discussed include chromatin in pluripotency, stem cells and DNA methylation, histone modifications in stem cells and differentiation, higher-order chromatin conformation in pluripotent cells, stem cells and cancer, epigenetics and disease modeling, brain organoids from pluripotent cells, transcriptional regulation in stem cells and differentiation, non-coding RNAs in pluripotency and early differentiation, and diseases caused by epigenetic alterations in stem cells. Additionally, the book discusses the potential implementation of stem cell epigenetics in drug discovery, regenerative medicine, and disease treatment. Stem Cell Epigenetics will provide researchers and physicians with a state-of-the-art map to orient across the frontiers of this fast-evolving field.
DNA. The double helix; the blueprint of life; and, during the early 1950s, a baffling enigma that could win a Nobel Prize. Everyone knows that James Watson and Francis Crick discovered the double helix. In fact, they clicked into place the last piece of a huge jigsaw puzzle that other researchers had assembled over decades. Researchers like Maurice Wilkins (the 'Third Man of DNA') and Rosalind Franklin, famously demonised by Watson. Not forgetting the 'lost heroes' who fought to prove that DNA is the stuff of genes, only to be airbrushed out of history. In Unravelling the Double Helix, Professor Gareth Williams sets the record straight. He tells the story of DNA in the round, from its discovery in pus-soaked bandages in 1868 to the aftermath of Watson's best-seller The Double Helix a century later. You don't need to be a scientist to enjoy this book. It's a page-turner that unfolds like a detective story, with suspense, false leads and treachery, and a fabulous cast of noble heroes and back-stabbing villains. But beware: some of the science is dreadful, and the heroes and villains may not be the ones you expect.
The Compact Guide: DNA provides a fascinating look at the world of the double helix and examines who we are, how we're wired, and how we repair ourselves. With information on so-called 'junk' DNA, how our genes evolved, heritability, the genetics of neuroscience, viruses, disease and what happens when things go wrong, this is a beautiful, visual journey through the polymer chain. The Compact Guide: DNA is an engaging and essential read for anyone captivated by the scope of human discovery, and reveals how we might just uncover the answers to the secrets of life on Earth.
This book describes the driving forces behind the evolutionary process at the molecular and genome levels, the effects of the various molecular mechanisms on the structure of genes, proteins, and genomes, the methodology and the analytical tools involved in dealing with molecular data from an evolutionary perspective, and the logic of evolutionary hypothesis testing.

Over the last twenty years, genome-wide association studies (GWAS) have revealed a great deal about the genetic basis of a wide range of complex diseases and they will undoubtedly continue to have a broad impact as we move to an era of personalised medicine. This authoritative text, written by leaders and innovators from both academia and industry, covers the basic science as well as the clinical, biotechnological and pharmaceutical potential of these methods. With special emphasis given to highlighting pharmacogenomics and population genomics studies using next-generation technology approaches, this is the first book devoted to combining association studies with single nucleotide polymorphisms, copy number variants, haplotypes and expressed quantitative trait loci. A reliable guide for newcomers to the field as well as for experienced scientists, this is a unique resource for anyone interested in how the revolutionary power of genomics can be applied to solve problems in complex disease.
Recent developments in behavioural neuroscience and genomics are providing exciting new tools for understanding mammalian evolution. Drawing on a range of disciplines including genomic reprogramming, immunology, genomic imprinting, placentation and brain development, this book examines the leading role played by the mother's genome and epigenome in the successful evolutionary progression of humans from ancestral mammals. Keverne begins by discussing the historic context of the perceived dominance of males and the patriline, before arguing that it is instead the matriline that exerts the dominant influence in shaping the evolution of our brain development and behaviour, especially the co-adaptive development of brain and placenta. Presenting a balanced outlook on the development of sex differences and an alternative to traditional views, Beyond Sex Differences will be of interest to anyone studying and researching mother and infant development.
This book opens with a discussion on the clinical applications of comet assay. Comet assay is rapid, simple method which able to assess DNA damage in different samples like blood, cells and tissues. Following this, the authors examine comet assay usage in occupational toxicology studies. Isolated lymphocytes were the most used cell line in these studies, but exfoliated cells such as nasal and buccal cell, liver, kidney and sperm cells may be used. Comet assay may also be used to detect nanoparticles-associated DNA damage. As such, this compilation assesses potential limitations due to the interaction of the nanoparticles with the method. Next, to shed light on the mechanisms of the DNA track formation, the authors apply an original approach based on the kinetic measurements in the comet assay, arguing that in neutral conditions at low levels of DNA damages, the comet tail is formed by extended DNA loops. New applications of the comet assay are described for the detection of aberrant DNA methylation, which is a promising marker in cancer diagnosis and follow-up. The authors go on to describe and analyse the results of in vitro treatment of lymphocytes with insecticide using comet assay under alkaline and neutral conditions, testing the commercial product Calypso (R) 480SC and its active agent thiacloprid at concentrations of 30; 60; 120; 240 and 480 g.ml-1. In one study, Helianthus annuus (sunflower) seedlings were irrigated with Hoagland solution containing different concentrations of AlCl3. Morphological parameters such as germination rate and stoma number are evaluated. Additionally, the genotoxic effects of endosulfan pesticide at different times and in different concentrations in wheat leaf samples are analyzed in two-week old wheat seedlings in an effort to demonstrate that endosulfan is a genotoxic agent causing DNA breaks in wheat. In the closing chapter, the correlation between the comet assay parameters, cell viability, and hydroquinone concentration is explored. The relationship between comet assay and remaining hydroquinone after fungal treatment is also investigated in order to evaluate its biodegradation efficiency.
A plasmid is a DNA molecule that is separate from, and can replicate independently of, the chromosomal DNA. They are double-stranded and circular in form. Plasmids usually occur naturally in bacteria, but are sometimes found in eukaryotic organisms. In this book, the authors present current research in the genetics, applications and health issues relating to plasmids. Topics include the development of multifunctional plasmids for diverse biotechnological applications; plasmids as indispensable components of multipartite azospirillum genomes; structural and segregational instability in plasmid biology; and conjugal plasmid transfer and phage inhibition kinetics.
Chromatin is DNA plus the proteins (and RNA) that package DNA within the cell nucleus. The primary functions of chromatin are: to package DNA into a smaller volume to fit in the cell, to strengthen the DNA to allow mitosis and meiosis and prevent DNA damage, and to control gene expression and DNA replication. In this book, the authors present topical research in the study of chromatin including the varied functions of aurora kinases A and B in mitosis and carcinogenesis; the chromatin state of pluripotent stem cells; MITF meets chromatin in melanoma; the state of chromatin as an integrative indicator of cell stress; analysing DNA damage and its repair throughout entire genomes; the cloning process, structural characterisation of Revolver transposon and its patented application for chromosome tags; DNA damage and Rad16; and glucocorticoid-induced chromatin remodelling.
Gene silencing is a general term describing the epigenetic processes of gene regulation. The term gene silencing is generally used to describe the "switching off" of a gene by a mechanism other than genetic modification. This book reviews research in the study of gene silencing including RNA silencing in transgenic plants and mycorrhizal research, gene silencing in the CNS and on the most extensively studied systems to mediate siRNA and shRNA delivery into the brain, siRNA delivery strategies as a therapeutic tool in gene therapy, galectin-3 epigenetics and effective methods for selecting siRNA sequences by using the average silencing probability and a hidden Markov model.
Stem cells are cells found in all multi cellular organisms. They are characterised by the ability to renew themselves through mitotic cell division and differentiate into a diverse range of specialised cell types. This book presents and discusses current research in the study of stem cell research, including cancer and prostate stem cells; neural stem cells and taurine; interactions between transplanted neural stem cells and host tissue; retrovirus vector silencing in stem cells and moral and scientific consideration in embryonic stem cell research.
Several problems in modern genome mapping analysis belong to the field of discrete optimisation on a set of all possible orders. In this book, formulations, mathematical models and algorithms for genetic/genomic mapping problem that can be formulated in TSP-like terms are proposed. Since the 1960s, Operational Research techniques have extensively been developed to support organisations in their Manpower Planning challenge -- a fundamental aspect of Human Resource Management in organisations. This book reviews the techniques and alternative approaches that have been introduced in Manpower Planning (e.g., simulation techniques), and in general, the Markov Chain Theory. Furthermore, the authors of this book propose a new class of strategies for giving the optimal inventory replenishments for each retailer. In addition, the authors demonstrate how to increase the usage of iterative methods in all possible fields by accelerating such solvers using Reconfigurable Hardware. An optimisation method for material layout of incompressible rubber components is presented as well. Other chapters in this book use a generic approach to study minimisation problems on a complete metric space, provide a novel design method in the case of an output feedback suboptimal control problem, derive Levy process-based models of jump diffusion-type for banking operations involving securitisation, capital and profitability, and investigate the optimality of the loan securitisation process that has had a prominent role to play in the sub-prime mortgage crisis (SMC).
This book presents the basic results on studies of the interaction of anti-cancer Actinomycin antibiotics with DNA. It focuses on interactions of heterocyclic anti-tumour antibiotics (Actinomycins, as typical example) with DNA, poly-nucleotides, oligonucleotides, and aggregates of purines, using spectroscopic methods. Experimental data, various models of structures of the complexes and their physical and chemical properties are described, and possible approaches for delivery of heterocyclic antibiotics to DNA are also discussed.
Telomerase is a ribonucleoprotein enzyme that catalyses the cellular synthesis of telomeric DNA during cellular division, resulting in maintenance of telomere length and increased proliferative potential. Several studies suggest that the telomerase may play an important role in the diagnosis and prognosis of cancer because its expression strongly correlates with the potential tumour progression. Ninety percent of human cancers on different organs have shown high telomerasa activity. This book reviews research in the field of telomerase including functions of telomerase independent of its interaction with telomeres on gene expression and chromatin structure; histone deacetylase inhibition as an anticancer telomerase-targeting strategy and others.
Genome stability of every species depends on complex interaction of predefined and environmentally induced genetic and epigenetic states. Predefined states consist of chromatin structure and cell metabolic processes such as DNA repair, radical scavenging and cell signalling, whereas induced states depend on interactions with the environment. Organisms are able to respond to a changing environment by various alterations in their somatic cells as well as in their germline and progeny. In this book, we will describe various phenomena associated with the maintenance of genome stability. These include genetic and epigenetic responses to various stresses in exposed cells and organisms, bystander and, bystander-like effects, transgenerational changes in genome stability and stress tolerance in bacteria, plants and animals.
Ribonucleotide reductase (RNR), a universal enzyme present in essentially all living cells and organisms, has a central role in DNA replication and repair by catalysing production of deoxyribonucleotides from the corresponding ribonucleotides. Three major classes of RNRs are known, differing in their cofactor requirements: class I RNRs (with subclasses Ia and Ib) carry a stable tyrosyl radical and are oxygen-dependent, class II RNRs require the vitamin B12 cofactor 5'-deoxyadenosylcobalamin and are oxygen-independent, and class III RNRs carry a stable glycyl radical and are oxygen-sensitive. Despite these differences, all classes have a similar reaction mechanism and the same highly specific catalytic core structure, indicating that they evolved from a common ancestor. Biochemical studies of RNRs from selected model organisms in combination with the vast number of deduced RNR sequences from publicly available complete genomic sequences show that whereas eukaryotes and their viruses with few exceptions contain only class Ia RNRs, all three major RNR classes are found among prokaryotes and bacteriophages and quite often one organism encodes more than one class of RNR. They are compiled in an open access database, called RNRdb for Ribonucleotide Reductase database that is available at http://rnrdb.molbio.su.se. RNRs are produced in a strictly controlled way depending upon growth phase and environmental cues. The authors describe a comprehensive summary of how the expression of RNR genes is regulated in several eubacterial organisms and in yeast. Due to RNR's importance for the realisation of DNA replication, it has been recognised as a possible target for antiproliferative therapy. The authors present a comprehensive summary of RNR-specific inhibitors that have reached clinical trials and/or are currently used in clinical therapy.
Gene silencing is a general term describing epigenetic processes of gene regulation. The term gene silencing is generally used to describe the 'switching off' of a gene by a mechanism other than genetic mutation. That is, a gene which would be expressed (turned on) under normal circumstances, is switched off by machinery in the cell. Genes are regulated at either the transcriptional or post-transcriptional level. Transcriptional gene silencing is the result of histone modifications, creating an environment of heterochromatin around a gene that makes it inaccessible to transcriptional machinery (RNA polymerase, transcription factors, etc.). Post-transcriptional gene silencing is the result of mRNA of a particular gene being destroyed. The destruction of the mRNA prevents translation to form an active gene product (in most cases, a protein). A common mechanism of post-transcriptional gene silencing is RNAi. Both transcriptional and post-transcriptional gene silencing are used to regulate endogenous genes. This book presents the latest research in this important field.
MiRNA is an extremely fast growing field, and miRNA knowledge is now believed to be a pivotal element of cancer biology. It is already evident that the discovery of miRNA has created a paradigm shift in post-genomics biology, not only for scientists accustomed to traditional central dogma of molecular biology but also for researchers studying human diseases and accustomed to traditional genetics approach of studying one gene at the time. This book provides an introduction to the basic principles of miRNA biology, overview of miRNA significance in the hallmarks of cancer, experimental techniques used in miRNA research, and in special part - miRNAs importance in wide range of solid cancers with a special focus on its potential usage in molecular pathology, predictive oncology or as a novel therapeutic targets. |
