Since the first edition of this book dedicated to differential display (DD) technology was published in 1997, we have witnessed an explosive interest in studying differential gene expression. The gene-hunting euphoria was initially powered by the invention of DD, which was gradually overtaken by DNA microarray technology in recent years. Then why is there still the need for second edition of this DD book? First of all, DD still enjoys a substantial lead over DNA microarrays in the ISI citation data (see Table 1), despite the h- dreds of millions of dollars spent each year on arrays. This may come as a surprise to many, but to us it implies that many of the DNA microarray studies went unpublished owing to their unfulfilled promises (1). Second, unlike DNA microarrays, DD is an "open"-ended gene discovery method that does not depend on prior genome sequence information of the organism being studied. As such, DD is applicable to the study of all living organisms-from bacteria, fungi, insects, fish, plants, to mammals-even when their genomes are not sequenced. Second, DD is more accessible technically and financially to most cost-conscious "cottage-industry" academic laboratories. So clearly DD still has its unique place in the modern molecular biological toolbox for gene expression analysis.

The endoplasmic reticulum (ER) is an extensive network of membranes that folds, modifies, and transports proteins in eukaryotic cells. It also manufactures lipids and interacts extensively with other organelles, playing essential roles in cell growth and homeostasis. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology covers all aspects of ER morphology and function, as well as its interactions with the nucleus, Golgi, and mitochondria. Contributors examine how proteins translocate across the ER membrane, the processes that occur inside the ER lumen (e.g., folding, glycosylation, and disulfide bond formation), and how the proteins are packaged into vesicles and transported to the Golgi. They also review quality-control mechanisms that are employed by the ER to detect and eliminate misfolded or unassembled proteins. Lipid synthesis and transport are also discussed. This volume covers not only the biochemistry and cell biology of the ER, but also ER stress, metabolism, and the role of the ER in viral replication. Thus, it is an essential reference for cell biologists, physiologists, and pathologists interested in understanding the numerous functions of the ER.

A number of chapters present the most novel research on testicular and epididymal functions or on more general fields of hormone action and molecular cell biology as it is now a tradition. However, exceptionally, the book also contains several chapters dealing with the "Approaches and Tools in the Third Millenium." The unusual inclusion of technologies as such in the 2000 edition of the workshop was an absolute necessity, as these technologies are revolutionizing the fields of biology and medicine and, in many instances, how to do research. This volume gives the scientific community essential information about the very latest technical developments and their potential for future progress.

Chapters have been divided in three parts focusing on theory and practical design of optical tweezers, detailed protocols for performing force measurements on single DNA- and microtubule/actin-associated mechanoenzymes in isolation, and describing recent advances that have opened up quantitative force measurements in living cells. Written in the highly successful Methods in Molecular Biology 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, Optical Tweezers: Methods and Protocols aims help to further expand the accessibility and use of optical traps by scientists of diverse disciplines.

Years ago when we were asked to write a book on the present-day knowledge of the molecular biology of poliovirus, we did not expect that such an apparently simple task could involve so much time and effort. Our writing was hampered by the fact that both of us are full time "workers," so that this monograph is mainly a spare time expedience. The main attention of this book focuses on a detailed review of the molecular biology of poliovirus and especially on the advances of the last decade; medical and environmental aspects are only briefly mentioned. Observations from older studies are considered in view of more recent information. Some of the older ob servations provided fundamental insights and paved the way for present day research; too often such data has been neglected or independently rediscovered. Today, poliovirus research has again attracted considerable interest. High points gained within the last few years were the elucidation of the complete nucleotide sequences of the RNAs of the three poliovinls serotypes and the corresponding vaccine strains, the demonstration of genome evolution during transmission of poliovirus in an epidemic, further characterization of the antigenic sites on the virus particle and of the antigenic drift, characterization of alternate conforma tional states of the virion capsid, the development of monoclonal antibodies against some of the virus proteins, observations on the role of the plasma membrane, cytoskeleton, and cytoplasmic membranes as mediators in the virus induced redirection of the synthetic machinery of the host cell, and characteriza"

In this second edition of a widely used classic laboratory manual, leading experts utilize the tremendous progress and technological advances that have occurred to create a completely new collection of not only the major basic techniques, but also advanced protocols for yeast research and for using yeast as a host to study genes from other organisms. The authors provide detailed methods for the isolation of subcellular components-including organelles and macromolecules, for the basic cellular and molecular analysis specific for yeast cells, and for the creation of conditional mutant phenotypes that lend themselves to powerful genome manipulation. Additional protocols offer advanced approaches to study genetic interactions, DNA and chromatin metabolism, gene expression, as well as the foreign genes and gene products in yeast cells.

Antigen processing and presentation, as a field, explores a broad range of protein interactions and functions, both intracellular (in the cytoplasm and in the endoplasmic reticulum) and at the cell surface (between T cells and MHC molecules). To investigate such a diverse array, it is necessary that biochemical, cell biology, and immunological techniques all be employed. The purpose of Antigen Processing and Presentation Protocols is therefore to detail the most up-to-date techniques being used in this burgeoning field. Such techniques include those used to question how MHC-binding peptides are generated, to test how peptides are delivered to MHC molecules, to analyze MHC peptide-binding patterns, and to assay the T-cell response to MHC/peptide. Antigen Processing and Presentation Protocols should aid both those new and those experienced in this area of research in extending the questions that can be asked and answered by the application of these current methods. For editorial assistance, I would like to thank Angela Beninga and Rachael Turnquist.

For more than four decades, Molecular Biology of the Cell has distilled the vast amount of scientific knowledge to illuminate basic principles, enduring concepts, and cutting-edge research. The Seventh Edition has been extensively revised and updated with the latest research, and has been thoroughly vetted by experts and instructors. The classic companion text, The Problems Book, has been reimagined as the Digital Problems Book in Smartwork, an interactive digital assessment course with a wide selection of questions and automatic-grading functionality. The digital format with embedded animations and dynamic question types makes the Digital Problems Book in Smartwork easier to assign than ever before-for both in-person and online classes.

With the advent of high-throughput technologies following completion of the human genome project and similar projects in model organisms, the number of genes of interest has expanded and the traditional methods for gene function analysis cannot achieve the throughput necessary for large-scale exploration. Gene Function Analysis brings together a number of techniques that have developed recently for looking at gene function, including computational, biochemical and biological methods and protocols.

Agrobacterium tumefaciens is a soil bacterium that for more than a century has been known as a pathogen causing the plant crown gall disease. Unlike many other pathogens, Agrobacterium has the ability to deliver DNA to plant cells and permanently alter the plant genome. The discovery of this unique feature 30 years ago has provided plant scientists with a powerful tool to genetically transform plants for both basic research purposes and for agricultural development. Compared to physical transformation methods such as particle bomba- ment or electroporation, Agrobacterium-mediated DNA delivery has a number of advantages. One of the features is its propensity to generate a single or a low copy number of integrated transgenes with defined ends. Integration of a single transgene copy into the plant genome is less likely to trigger "gene silencing" often associated with multiple gene insertions. When the first edition of Agrobacterium Protocols was published in 1995, only a handful of plants could be routinely transformed using Agrobacterium. Agrobacterium-mediated transformation is now commonly used to introduce DNA into many plant species, including monocotyledon crop species that were previously considered non-hosts for Agrobacterium. Most remarkable are recent developments indicating that Agrobacterium can also be used to deliver DNA to non-plant species including bacteria, fungi, and even mammalian cells.

Since the first international meeting on Vitamin B6 involvement in catalysis took place in 1962, there have been periodic meetings every three or four years. In 1990, scientists studying another cofactor, PQQ, which had already attracted the scientific community's interest for its possible involvement in amino acid decarboxylation and reactions involving amino groups, joined forces with those investigating pyridoxal phosphate-dependent enzymes. Since then, the international PQQ/quinoproteins meetings have been held jointly. In the years following the original meeting 37 years ago in Rome, Italy, the scientific gatherings have taken place in Moscow, Russia (1966); Nagoya, Japan (1967); Leningrad (St. Petersburg), Russia (1974); Toronto, Canada (1979); Athens, Greece (1983); Turku, Finland (1987); Osaka, Japan (1990); and Capri, Italy (1996). For the first time in the history of these symposia, the international meeting was held in the United States, from October 31 through November 5, 1999, in Santa Fe, New Mexico. The scientific program focus shifted significantly beyond the original emphasis on catalysis to aspects such as cellular and genetic regulation of events involving proteins that require pyridoxal phosphate or quinoproteins. The growing awareness of the involvement of these proteins in biotechnology processes and fundamental physiological events, as well as their implication in diseases, was also represented, with emphasis on the molecular basis of these events. The meeting was symposium S278, sponsored by the International Union of Biochemistry and Molecular Biology (IUBMB).

Putrescine and spermidine are ubiquitous in living organisms. Spermine, third of the three most commonly occurring natural polyamines, is probably present in all eukaryotes but is rare (or nonexistent) in prokaryotes. Polyamine residues are constituents of many compounds found in plants and insects. Putrescine, spermidine, or spermine-containing alkaloids are found in many plants, nonproteinaceous spider and wasp toxins contain polyamine residues, and glutathionyl-spermidine conjugates have been found in some pathogenic microorganisms. In most cells polyamines are the products of a highly regulated bios- thetic pathway. It is not clear whether the elaborate regulation of polyamine synthesis is a consequence of their essential role(s) in cellular differentiation and development, or part of a defense mechanism to prevent overaccumulation of compounds that are toxic in excess. In addition to their biosynthetic capa- bility, many cells also possess transport systems for polyamines that respond to intracellular polyamine levels, and other stimuli, and are regulated by mecha- nisms that are at present incompletely defined. Two routes of polyamine catabolism have been identified in mammalian cells, a biodegradative route and a recycling pathway. The relative impor- tance of these pathways and their overall regulation is only partially resolved. What is clear is the widespread occurrence of a variety of polyamine-oxid- ing enzymes in animals, plants, bacteria, and fungi. Polyamine catabolism, by whichever route, results in the formation of aminoaldehydes as intermediates.

Detailed protocols for the isolation of short- and long-term culture of the adult mouse cardiac myocytes are also included.

Numerous advanced proteomic techniques are addressed, including protein separation by two-dimensional electrophoresis and two-dimensional difference gel electrophoresis, liquid chromatography coupled to mass spectrometry, and the SELDI-TOF approach to searching for biomarkers of stroke in human serum or of hypertension in the serum of animal models. Proteomic strategies and protocols for studying the proteome of endothelial, arterial smooth muscle cells, foam cells, and circulating blood monocytes constitute a major element of this text. Cutting-edge techniques for the analysis of subproteomes from isolation to final characterization and the characterization of posttranslational modifications are also addressed. This useful snapshot of current proteomic techniques is a single source for protocols for the identification and validation of novel biomarkers and targets in cardiovascular diseases.

The innate immune response is a crucial component of early resistance to infection, and it is now revealing increasing levels of complexity. The ability to modify the genome in vivo, has facilitated understanding of complex interactions between leucocytes and other components of the immune system, and phenotype-driven strategies using chemical mutagenesis have placed another powerful weapon in the armamentarium. In, Leucocytes: Methods and Protocols provides detailed protocols and practical advice on a variety of modern approaches to the study of leucocytes and their products. 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 key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Leucocytes: Methods and Protocols seeks to aid scientists in further study into the immune system and leucocytes.

A self-taught scientist determined to bring science out of the laboratory and into the practical arena, French-Canadian Felix d'Herelle (1873-1949) made history in two different fields of biology. Not only was he first to demonstrate the use and application of bacteria for biological control of insect pests, he also became a seminal figure in the history of molecular biology. This engaging book is the first full biography of d'Herelle, a complex figure who emulated Louis Pasteur and influenced the course of twentieth-century biology, yet remained a controversial outsider to the scientific community.

Drawing on family papers, archival sources, interviews, and d'Herelle's published and unpublished writings, Dr. William C. Summers tells the fascinating story of the scientist's life and the work that took him around the globe. In 1917, d'Herelle published the first paper describing the phenomenon of the bacteriophage and its biological nature. A series of more than 110 articles and 6 major books followed, in which d'Herelle established the foundation for the later work of Max Delbruck and the Phage Group in molecular biology. Yet d'Herelle sometimes inspired animosity in others -- he was drummed out of the Pasteur Institute, he held only one brief permanent position in the scientific establishment (at Yale University from 1928 to 1933), and he was bewildered by the social nuances of the world of international science. His story is more than the biography of a single brilliant scientist; it is also a fascinating chapter in the history of biology.

During the past decade as the data on gene sequences and expression patterns rapidly accumulated, cell-free protein synthesis technology has also experienced a revolution, becoming a powerful tool for the preparation of proteins for their functional and structural analysis. In Cell-Free Protein Production: Methods and Protocols, experts in the field contribute detailed techniques, the uses of which expand deep into the studies of biochemistry, molecular biology, and biotechnology. Beginning briefly with basic methods and historical aspects, the book continues with thorough coverage of protein preparation methods, the preparation of proteins that are generally difficult to prepare in their functional forms, applications of the cell-free technologies to protein engineering, as well as some methods that are expected to constitute a part of future technologies. Written in the highly successful Methods in Molecular Biology series format, the chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls.

Authoritative and cutting-edge, Cell-Free Protein Production: Methods and Protocols aims to help researchers continue the growth of the vital exploration of cell-free sciences and technologies in order to better understand the dynamic lives of cells.

The study of animal viruses contributes to the general understanding of the molecular basis of viral infection. The emergence of the SARS (Severe Acute Respiratory Syndrome) virus in the human population, coming from an animal source, highlights the importance of animals in harboring infectious agents. In addition, it has been recognized recently that influenza viruses, which persist in their natural avian host, can directly infect humans. In this book, an international panel of leading virologists provide a state-of-the-art overview of the field, comprehensively detailing the current understanding of viruses, their replication, evolution, and interaction with the host. The authors emphasize strategic and methodological aspects of current research, and provide key related references. Topics include foot-and-mouth disease virus, Pestivirus, Arteriviridae, Coronaviruses (including SARS), Herpesviridae, Paramyxoviridae, influenza viruses, Reoviridae, porcine circoviruses, Asfarviridae and much more.

advanced metastatic disease of solid tumors, dictates that each tumor mass, indeed each individual metastasis, will have a unique antigen and cytokine environment and hence unique response to immune modu lation. A differential response to immunotherapy is thus inevitable. 4. Many of the human trials described are not randomized and report survival or response against historical controls. Most tumors described are immunogenic human tumors: renal cell cancer and melanoma are most common. In order to avoid the well-described inter-patient vari ation and rare incidence of spontaneous response among patient samples as well as selection bias and changes in practice over time, randomized trials are required. 5. Immunological treatment is unlike conventional chemotherapy in its endpoint. Most chemotherapeutic regimes require a complete response or a good partial response for cure or good palliation. There are now many cases where immunotherapy has provided long-term palliation without massive tumor reduction. Immunity may be stimulated to a degree which holds tumorigenicity in check and most importantly, pro vides good palliation for the patient in a manner that differs essentially from chemotherapy."

The aim of Plant Proteomics: Methods and Protocols is to present up-- date methods and protocols used by recognized scientists in the world of plant proteomics. If this world was a very small one twenty-five years ago when the first papers were published, it has since experienced exponential growth, and in most countries around the world there are laboratories working on plant proteomics. Two-dimensional gel electrophoresis is still the basic method used, but it has been improved greatly with IPG in the first dimension (Chapter 13) and with new detection methods with fluorochromes (Chapters 14 and 15). Signi- cant progress has been achieved in protein extraction, which is particularly difficult with plant tissues containing phenols, proteases, and other secondary metabolites that interfere with proteins. Standard procedures have been op- mized (Chapters 1 and 2) for peculiar tissues (Chapters 3, 4, and 5) and cellular compartments (Chapters 6 to 10). These methods rely on improvements made in the solubilization of proteins from membranes (Chapters 11 and 12). Mass spectrometry was a revolution that permitted the high throughput identifi- tion of proteins separated by 2D gels (Chapters 19 and 20) but also from blue native 1D gels (Chapters 27 and 28) despite the fact that Edman sequencing can still be useful (Chapter 18). Associated with other techniques such as 2DLC or LC of intact proteins, mass spectrometry also permits the identification of polypeptides from complexes (Chapters 21 and 22).

In Molecular Embryology: Methods and Protocols, Second Edition, expert investigators provide a comprehensive guide to the cutting-edge methods used across the dramatically growing field of vertebrate molecular embryology. Time-tested techniques take advantage of the most commonly used vertebrate experimental models: murine embryos for their genetics, chick embryos for in vivo manipulation, zebrafish for mutagenesis, amphibian embryos, and nonvertebrate chordates. The second edition collects classic protocols which have become standard techniques in the laboratory and presents them in a complementary fashion with novel and emerging approaches, allowing researcher to become more familiar with commonly studied embryos used in biomedical research. Insightful to the experienced professional, Molecular Embryology: Methods and Protocols, Second Edition, presents cutting-edge findings of perhaps the greatest period in growth and productivity in the field of developmental biology.
