This comprehensive volume completes Frederic Holmes's notable and detailed biography of Hans Krebs, from the investigator's early development through the major phase of his groundbreaking investigation, which lay the foundations upon which the modern structure of intermediary metabolism is built. With access to Krebs's research notebooks as well as to Krebs himself through more than five years of personal interviews, the author provides an insightful analysis of Hans Krebs and of the scientific process as a whole. The first volume, published in 1991, covered Krebs's formative years in Germany, his work with Otto Warburg, and his discovery of the urea cycle in 1932. This second volume reconstructs the investigative pathway and the professional and personal life of Hans Krebs, from the time of his arrival in England in 1933 until 1937, when he made the discovery for which he is best known-the formulation of the citric acid cycle. Holmes portrays Krebs's activity at the intimate level of daily interactions of thought and action, from which the characteristic patterns of scientific creativity can best be seen. Holmes's fascinating portrait of Krebs integrates the great scientist's investigative pathways with his personal life. The result is an illuminating analysis of both man and scientist that will be of interest to biochemists and historians of science.

This volume explores the epigenetic alterations and their association with various human cancers. Considering one of human cancer as an example, individual chapters are focused on defining the role of epigenetic regulators and underlying mechanisms in cancer growth and progression. Epigenetic alteration including DNA methylation, histone modification, nucleosome positioning and non-coding RNAs expression are involved in a complex network of regulating expression of oncogenes and tumor suppressor genes and constitute an important event of the multistep process of carcinogenesis. Recent advances in the understanding of the epigenetic regulation and detailed information of these epigenetic changes in various cancers provide new avenues of advancements in diagnostics, prognostics, and therapies of this highly fatal disease.

Epigenetics is a rapidly expanding field in medical and biological research which concerns heritable traits that are not attributable to changes in the DNA sequence. Epigenetic mechanisms play key roles in many biological processes, and it has become clear that their disruption can gives rise to diverse pathologies in humans. Edited by preeminent experts, Sophie Rousseaux and Saadi Khochbin, this volume in the Epigenetics and Human Health' series discusses the role of epigenetics in human reproduction. The book presents epigenetic transitions that are important at defined stages of gametogenesis and during meiosis. Several of the sixteen chapters written by experts in the field cover fundamental concepts discovered through cellular and biochemical work and from research on animal models. In other chapters, key examples are provided of how disruption of these mechanisms affects germ cell development and fertility, and contributes to the germinal cancers. Finally, the book discusses how in vitro manipulation and culture in assisted reproduction can epigenetically perturb germ cells, and how this can trigger disease phenotypes in the next generation. Conceived towards advanced students, medical professionals and research scientists, this is the first comprehensive textbook on this topic that will serve as a valuable reference during the years to come.
The eukaryotic translation machinery must recognize the site on a messenger RNA (mRNA) where decoding should begin and where it should end. The selection of the translation start site is generally given by the ?rst AUG codon encoding the amino acid methionine. D- ing initiation soluble translation initiation factors (eukaryotic translation initiation factors [eIFs] in eukaryotes and prokaryotic translation initiation factors [IFs] in prokaryotes) bind the mRNA, deliver the initiator Met-tRNA, and assemble to form a complete 80S ribosome from the 40S and 60S subunits. By progressing along the mRNA in the 5 -to-3 direction the ribosome decodes the information and translates it into the polypeptide chain. During this process, repeated delivery of amino-acyl tRNA (aa-tRNA) to the ribosome, peptide bond formation, movement of the mRNA, and the growing peptidyl-tRNA is mediated by both soluble elongation factors (eukaryotic translation elongation factors [eEFs] in euka- otes and prokaryotic translation elongation factors [EFs] in prokaryotes) and the activity of the ribosome. The ?nal step in the translation process occurs when one of the three t- mination codons occupies the ribosomal A-site. Translation comes to an end and soluble release factors (eukaryotic translation termination factors [eRFs] in eukaryotes and proka- otic translation termination factors [RFs] in prokaryotes) facilitate hydrolytical release of the polypeptide chain (for recent reviews, see Inge-Vechtomov et al. 2003; Kisselev et al. 2003; Wilson and Nierhaus 2003; Kapp and Lorsch 2004).
The craniofacial musculature, including the extraocular muscles, muscles associated with the auditory system, the masseter, the tongue, and the laryngeal and pharyngeal muscles, all participate in functions that are critical to life: vision, intact of nutrition, breathing, and hearing. Despite their critical importance, the majority of research on skeletal muscle basically has ignored this collection of muscles. This is most likely due to their complexity in form, development, fiber types, physiology, and disease profiles. All these make these muscles extremely difficult to study. Vision depends on voluntary and reflexive eye movements initiated by the oculomotor system. The effector arm of this motor system includes the extraocular muscles and their motor neurons. Mastication, and therefore food intake, depends on the complex movements of the masseter and tongue musculature. The effector arm of this motor system includes the masseter and tongue muscles and their motor neurons. Respiration, human phonation, as well as gestation, depend on the laryngeal and pharyngeal musculature. The effector arm of these motor systems includes the intrinsic and extrinsic laryngeal muscles and the pharyngeal muscles and their motor neurons. Recently there has been a renewed interest in understanding the basic cell biology and pathologies associated with these unusual skeletal muscles. This book will highlight novel findings on the development of these muscles and their innervation, metabolic design, functional consequences of their structural organization, and potential reasons for their differential response to various neuromuscular diseases. In addition, critical areas for future studies will be identified.

This book discusses the emergence of a new class of genes with a specific anticancer activity. These genes, recently defined as "Anticancer Genes", are reviewed in individual chapters on their mode of action, the specific cell death signals they induce, and the status of attempts to translate them into clinical application. Anticancer Genes provides an overview of this nascent field, its genesis, current state, and prospect. It discusses how Anticancer Genes might lead to the identification of a repertoire of signaling pathways directed against cellular alterations that are specific for tumor cells. With contributions from experts worldwide, Anticancer Genes is an essential guide to this dynamic topic for researchers and students in cancer research, molecular medicine, pharmacology and toxicology and genetics as well as clinicians and clinical researchers interested in the therapeutic potential of this exciting new field.
As cells mature they naturally stop dividing and enter a period called senescence. But cellular senescence can also be induced prematurely by certain oncogenes involved in cancer development. Cellular senescence, a growth-arrest program that limits the lifespan of mammalian cells and prevents unlimited cell proliferation, is attracting considerable interest because of its links to tumor suppression.
In the last forty years anthropologists have made major contributions to understanding the heterogeneity of reproductive trends and processes underlying them. Fertility transition, rather than the story of the triumphant spread of Western birth control rationality, reveals a diversity of reproductive means and ends continuing before, during, and after transition. This collection brings together anthropological case studies, placing them in a comparative framework of compositional demography and conjunctural action. The volume addresses major issues of inequality and distribution which shape population and social structures, and in which fertility trends and the formation and size of families are not decided solely or primarily by reproduction.
This volume will explore the latest findings in research into the genetics of breast and reproductive cancers, covering the epidemiological aspects of these cancers, their etiology, the effect of environment on genes and cancer etiology, and how research in this area can lead to development of preventative measures and treatments.
Biological rhythms time the ebb and flow of virtually every physiological process, and their mutual coordination guarantees the integrity of the organism over space and time. Aging leads to the disintegration of this coordination, as well as to changes in the amplitude and/or frequency of the underlying rhythms. The results of this are accelerated loss of health during aging, and in experimental model systems curtailed lifespan occurs. This book will examine the machinery that constitutes circadian systems and how they impact physiologic processes. It will also discuss how disturbances of circadian rhythms can lead to complex diseases associated with aging. Much of this treatment will focus on metabolism and genome stability. Importantly, the chapters in this book will encompass work in several different models, in addition to human. The book will conclude with a discussion of modeling approaches to biologic cycles and chronotherapy, for future research and translation.
Human cell culture is not a new topic, but the development of new molecular techniques and reagents which can be used to investigate cell function and the responsible intracellular mechanisms make it a continuing requirement. This third edition of Human Cell Culture Protocols expands upon the previous editions with current, detailed protocols for the isolation and culture of a range of primary cells from human tissues. With new chapters on pancreatic cells needed for basic studies on the pathogenesis of diabetes and for their application for islet transplantation, the book also delves into protocols for hepatocytes, skin cells, lung cells, parathyroid cells, gastric cells, renal cells, adipocytes, ovarian cells, bone cells, vascular smooth muscle cells, vascular endothelial cells, regulatory T cells, blood mononuclear cells, as well as new techniques being applied to human cell culture, particularly the use of biocompatible scaffolds to grow cells, the in vitro use of laser microdissection to isolate cells from culture, and automated cell culture. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Human Cell Culture Protocols, Third Edition makes it possible for a worker with basic cell culture training, whether in the fields of cell biology, gene therapy, and cell transplantation, to prepare cell cultures of the specific cell type necessary to forward their vital research.
