If theoretical physicists can seriously entertain canonical "standard models" even for the big-bang generation of the entire universe, why cannot life scientists reach a consensus on how life has emerged and settled on this planet? Scientists are hindered by conceptual gaps between bottom-up inferences (from early Earth geological conditions) and top-down extrapolations (from modern life forms to common ancestral states). This book challenges several widely held assumptions and argues for alternative approaches instead. Primal syntheses (literally or figuratively speaking) are called for in at least five major areas. (1) The first RNA-like molecules may have been selected by solar light as being exceptionally photostable. (2) Photosynthetically active minerals and reduced phosphorus compounds could have efficiently coupled the persistent natural energy flows to the primordial metabolism. (3) Stochastic, uncoded peptides may have kick-started an ever-tightening co-evolution of proteins and nucleic acids. (4) The living fossils from the primeval RNA World thrive within modern cells. (5) From the inherently complex protocellular associations preceding the consolidation of integral genomes, eukaryotic cell organization may have evolved more naturally than simple prokaryote-like life forms. - If this book can motivate dedicated researchers to further explore the alternative mechanisms presented, it will have served its purpose well.

It has been established that TNF receptor associated factors (TRAFs) are critical signaling mediators for not only the TNF receptor superfamily, but also the interleukin-1 receptor/Toll-like receptor superfamily and the T-cell receptors. They play important roles in mammalian biology including embryonic development, innate and adaptive immune regulation and maintenance of cellular homeostasis. Agents that manipulate the signaling of these receptors are being used or showing promise towards the treatment and prevention of many human diseases such as rheumatoid arthritis, coronary heart disease, transplantation rejection, insulin resistance, multiple organ failure and cancer. TNF Receptor Associated Factors is the only literature that is entirely devoted to TRAFs. Almost every aspect of TRAF signaling is covered, including the different TRAF family members, their distinct biological functions, the TRAF structures, their modes of receptor recognition, the signaling mechanisms, and the roles of TRAFs in normal cellular functions and in viral infection. TNF Receptor Associated Factors is intended for a wide audience, including researchers in the field of TRAF signaling and students and postdoctoral fellows learning cell biology and cell signal transduction. This exciting new volume is up to date on the most recent advances in TRAF signal transduction.

Complex molecular mechanisms involving microbiology and immunology define the host-pathogen relationship. These mechanisms can be the basis for new drugs and vaccine design. This book provides information on the molecular interactions between host cell organelles and pathogens, which have developed strategies to survive within infected cells. Chapters are grouped into five sections: I. Endocytosis and phagocytosis. Collectively, the chapters of this section review basic knowledge regarding intracellular organelles are involved in membrane interactions with pathogen-containing vacuoles. II. Professional and non-professional phagocytes. Here the authors describe the major differences between the two host cell types, which can be infected by microorganisms. III. Maturation pathways of bacteria-containing vacuoles. Molecular interactions between vacuoles and intracellular organelles leading to the search of the Holy Grail, the replication niche, are described. IV. Host response. Host cells are able to react against intruders and eventually mount host responses. In these chapters the various types of host response mechanisms against intracellular intruders are reviewed. V. knowledge of bacteria-host cell interactions will be acquired fast enough to find the necessary tools for controlling microorganism development. This comprehensive book should appeal to scientists interested in cell biology, microbiology and immunology, as well as to clinically-oriented investigators concerned with infectious diseases.

Alzheimer's disease is the most common cause of senile dementia. Since the discovery in 1984 of the amyloid ?-peptide (A?) as the core protein of the senile plaques present in the brains of Alzheimer's disease sufferers, an immense amount of research has gone into mapping out the molecular basis of this debilitating disease. The aim of Alzheimer's Disease: Methods and Protocols is to bring together the main biochemical, cell biological, and molecular biological techniques and approaches that are being used to investigate the molecular basis of Alzheimer's disease. This volume begins with chapters of an introductory/ review nature. Chapter 1 provides a historical introduction to Alzheimer's d- ease with particular emphasis on the central role played by A? and its re- tion to tau. Chapter 2 examines the genetics underlying this neurodegenerative disease, covering the amyloid precursor protein, apolipoprotein E, and the presenilins. Chapter 3 presents an overview of currently available therapeutic agents and prospects for drugs of the future.

The last few years have seen an explosion of new information and resources in the areas of plant molecular genetics and genomics. As a result of developments such as high throughput sequencing, we now have huge amounts of information available on plant genes. But how does this help people charged with the task of improving crop species to create products with altered functions or improved characteristics? This volume considers ways in which the new information, resources and technology can be exploited by the plant breeder. Examples in current use will be quoted wherever possible.

In 1868, Ernst Neumann recognized that blood cells re quire continuous replenishment during postnata1life. Before him, the assumption was that cells of the blood, like nerves once formed in the embryo, remain in the body throughout life. Neumann also recognized that this process occurred within the bone marrow, because this tissue provided a fa vorable environment for proliferation and differentiation of blood cell precursors. Vera Danchakoff, the Russian embryologist working in the US, in 1916 made an analogy to the soil and the seed. Bone marrow forms the soil, providing a favorable environment for the growth of seed, the hemopoietic stem cell, and other progenitor cells. Imagine in the remote past a heap of similar tree seeds. These seeds develop in our moderate climate into a tall and many branched tree. Suppose the wind bears a part of the seeds away and brings them to a land possessing different environmental conditions, we will say the arc tic lands. There the seeds may develop but they may pro duce trees no higher than our moss."

The incentive for putting together Volume 4 of this series was to review the wealth of new information that has become available in prokaryotic organisms in protein export and membrane biogenesis. Just in the last several years, protein translocation has now been efficiently reconstituted using defined components and the mechanism by which proteins are moved across membrane bilayers is now being examined at a higher resolution. In addition, because of a new technical breakthrough using osmolytes, it is now possible to reconstitute a number of channel proteins, ATPase, receptors, and transporters. In many cases, it is possible to successfully predict the membrane topology of these types of proteins using both "hydrophobicity analysis" and the "positive inside" rule.
In this volume, two chapters focus on protein translocation across membranes ("Biochemical Analyses of Components Comprising the Protein Translocation Machinery of E. Coli; Protein Translocation Genetics"), while several others on how proteins assemble into the ineer membrane of E. Coli ("Membrane Protein Assembly; Membrane Insertion of Small Proteins: Evolutionary and Functional Aspects; Pigment-Protein Complex Assembly in Rhodobacter sphaeroides and Rhodobacter Capsulatus"). Other sections review recent progress on transporters ("Identification and Reconstitution of Anion Exchange Mechanisms in Bacteria; Helic Packing in the C-Terminal Half of Lactose Permease") and signal transduction ("Mechanism of Transmembrane Signaling in Osmoregulation") as well as the assembly of prints into the outer membrane ("Export and Assembly of Outer Membrane Proteins in E. coli"). Although the emphasis of the book is on proteins, the role of phospholipids in controlling various cell surface processes is reviewed ("Role of Phospholipids in coli Cell Function"). I should point out the reason for the rapid progress in bacteria research is because of the possibility to apply biochemistry and genetics in this organism.

Interest in retinoic acid, the main biologically active derivative of vi- min A or retinol, increased dramatically between 1989 and 1993, following the cloning of nuclear receptors or RARs reported in 1987 (Fig. 1). Important discoveries since then have shown how RARs work as all-trans retinoic ac- dependent heterodimers with related nuclear receptors for 9-cis retinoic acid called RXRs. This has stimulated the development of synthetic analogs s- cific for each type of receptor, and opens the way to develop new methods for regulating pharmacologically the activity ofretinoic acid-dependent pathways of gene activation. The potential for the development of new drugs by the pharmaceutical industry is now a maj or factor driving forward our understa- ing of vitamin A-regulated pathways in animal development and homeostasis. However, apart from the real potential ofretinoid analogs as novel pharma- logical agents, there remains the considerable intellectual challenge of und- standing the way in which vitamin A and its derivatives function in cell development and differentiation. Retinoid Protocols is an attempt to bring together various methodologies that will be vital for rising to this challenge in the future. Retinoid molecular biology has few methods of its own, but is reliant on standard molecular biology methods applied to this particular research area.

In this contribution, several specialists describe the early-21st century knowledge on the molecular networks that regulate cell cycle progression, with an emphasis on the G1 phase of the cell cycle. The first part of Regulation of G1 Phase Progression is concerned with the individual molecules that form the network, including cyclins, cyclin-dependent kinases, inhibitors of these kinases and retinoblastoma and p53. The second section describes the signaling cascades by which external factors influence the cell cycle network, including mitogens, the extracellular matrix, nutrients and oxygen radicals. The last section describes the effects of specific external conditions on cell cycle progression and are presented such as serum starvation and subsequent re-addition and stress conditions (heat, osmolarity). The final two chapters describe the relation between cell cycle progression with cell differentiation and with apoptosis.

Cell Surface Receptors: A Short Course on Theory and Methods, Second Edition is a primer for the study of cell surface receptors. The simplified discussion of methods and their underlying principles removes the usual intimidation caused by the specialized vocabulary or sophisticated mathematics that characterize many of the primary papers in this field. In this way, the basic concepts become emphasized. This volume is a starting point: a textbook as well as a manual to which the investigator can return for a refresher course, when needed.

All three peroxisome proliferator-activated receptor (PPAR) subtypes share a high degree of structural homology while exhibiting differences in function, tissue distribution, and ligand specificity. In Peroxisome Proliferator-Activated Receptors: Discovery and Recent Advances, the authors trace the history of PPAR discovery and detail the receptor structure and its posttranslational modifications. Furthermore, endogenous ligands as well as various classes of exogenous ligands, subtype-selective, dual and pan agonists as well as antagonists, are discussed. In addition, the tissue distribution and versatile functions of PPAR subtypes in major organs are described. As PPARs play critical roles as regulators of numerous physiological as well as pathophysiological pathways, Peroxisome Proliferator-Activated Receptors: Discovery and Recent Advances aims to help researchers to develop safer and more effective PPAR modulators as therapeutic agents to treat a myriad of diseases and conditions.

The three-dimensional organization of the DNA inside the eukaryotic cell nucleus has emerged a critical regulator of genome integrity and function. Increasing evidence indicates that nuclear pore complexes (NPCs), the large protein channels that connect the nucleus to the cytoplasm, play a critical role in the establishment and maintenance of chromatin organization and in the regulation of gene activity. These findings, which oppose the traditional view of NPCs as channels with only one: the facilitation of nucleocytoplasmic molecule exchange, have completely transformed our understanding of these structures. This book describes our current knowledge of the role of NPCs in genome organization and gene expression regulation. It starts by providing an overview of the different compartments and structures of the nucleus and how they contribute to organizing the genome, then moves to examine the direct roles of NPCs and their components in gene expression regulation in different organisms, and ends by describing the function of nuclear pores in the infection and genome integration of HIV, in DNA repair and telomere maintenance, and in the regulation of chromosome segregation and mitosis. This book provides an intellectual backdrop for anyone interested in understanding how the gatekeepers of the nucleus contribute to safeguarding the integrity and function of the eukaryotic genome.

Since the pioneering discoveries of Hodgkin, Huxley, and Katz, it has been clear that specific ion conductance pathways underlie electrical act- ity. Over the ensuing 50 years, there has been ever increasing, and occasi- ally explosive, changes in the scope of efforts to understand ion channel behavior. The introduction of patch clamp technology by Erwin Neher and Bert Sakmann about 20 years ago led to the realization of the great variety of novel ion channel species, and the subsequent revolution in cl- ing has revealed an even greater diversity of the underlying molecular entities. Today, advances in the study of ion channel structure and function c- tinue at a high pace, from angstrom resolution imaging of crystallized ch- nels to their genetic manipulations in animals. In this regard, the field is a balanced one that inquires not only what ion channel entities are there, or how they operate, but also where are these molecular electronic switches? However, this balance is not particularly well presented to the general sci- tific audience or to specialists in the field. There are plenty of wonderful and useful books and monographs, as well as conferences and meetings on v- tually every aspect of ion channel structure and function. However, we are unaware that the channel localization theme has been considered in a u- fied forum.
