Download or read book The Development Of Dictyostelium Discoideum written by William Loomis and published by Elsevier. This book was released on 2012-12-02 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Development of Dictyostelium discoideum consists of 11 chapters representing the 11 major aspects at which continuous progress are made in the study of Dictyostelium discoideum. This book begins with the discovery, classification, ecology, and development of Dictyostelium discoideum. It then outlines the advances in genetic manipulation and mutant isolation of the organism. Much of the advances in cell biology have been related to a better understanding of the composition and function of the cell membrane. Hence, analyses of Dictyostelium plasma membranes are collated. This reference material also describes the role of chemoattractants in organizing cell movements and the intracellular events triggered by occupancy of chemoreceptors. It also explains the understanding of the macromolecular components of the chemosensory system of Dictyostelium discoideum. It further discusses the cell motility, cell adhesion, morphogenetic signaling, cytodifferentiation, and gene expression in the species. Finally, the phenomenon of cell-type specification and regulation in this organism is addressed. This book will be valuable for those already familiar with the general outlines of Dictyostelium biology.

Download or read book The Biology of Glycoproteins written by Raymond Ivatt and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is in many ways a sequel to The Biochemistry ojGlycoproteins and Proteoglycans. The enormous recent progress in understanding the biological roles of glycoproteins has prompted the present volume. The reasons for studying glycoproteins have multiplied, and in the present volume the roles played by glycoproteins are explored in a variety of biological situations. The first two chapters describe molecules involved in cell-substratum and cell-cell interactions in a broad sense, and also focus on recent progress in identifying specific attachment molecules. Our understanding of how normal processes, such as cellular differentiation and tissue organization, are regulated is dependent on understanding how cells interact with the extracellular matrix. When these processes go awry the consequences can be tragic, for example, when manifest as birth de fects and cancer. Our ability to devise appropriate therapies is in many cases limited by our understanding of such cell-matrix interactions. The third chapter explores the roles by glycoproteins during early mammalian development. The carbohydrate portions c1early play very important roles in presenting information during early embryogenesis, and an unusual tumor stern cell, the embryonal carcinoma, looks very promising in pro viding an experimental system for understanding how the expression of these complex carbohydrate determinants is regulated. The next three chapters explore the biology of glycoproteins in distinct situations: in the immune system, in the nervous system, and during erythropoiesis.
Download or read book Dictyostelium discoideum Protocols written by Ludwig Eichinger and published by Springer Science & Business Media. This book was released on 2008-02-02 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dictyostelium discoideum is a simple but fascinating eukaryotic microorg- ism, whose natural habitat is deciduous forest soil and decaying leaves, where the amoebae feed on bacteria and grow as independent single cells. Exhaustion of the bacterial food source triggers a developmental program, in which up to 100,000 cells aggregate by chemotaxis towards cAMP. Morphogenesis and cell different- tion then culminate in the production of spores enabling the organism to survive unfavorable conditions. Dictyostelium offers unique advantages for studying f- damental cellular processes with the aid of powerful molecular genetic, bioche- cal, and cell biological tools. These processes include signal transduction, chemotaxis, cell motility, cytokinesis, phagocytosis, and aspects of development such as cell sorting, pattern formation and cell type differentiation. Recently, D- tyostelium was also described as a suitable host for pathogenic bacteria in which one can conveniently study the process of infection. In addition, Dictyostelium has many of the experimental conveniences of Saccharomyces cerevisiae and is pr- ably the best experimentally manipulatable protozoan, providing insight into this diverse group of organisms, which includes some of the most dangerous human parasites. The recent completion of the Dictyostelium genome sequencing project strengthens the position of D. discoideum as a model organism. The completed genome sequence and other valuable community resources constitute the source for basic biological and biomedical research and for genome-wide analyses.
Download or read book Molecular Approaches to Supracellular Phenomena written by Stephen Roth and published by University of Pennsylvania Press. This book was released on 2016-11-11 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on a group of diverse developmental processes that have resisted incisive analysis when conventional genetic and biochemical methodologies were employed. Relatively little is known at the molecular level about these processes, but the contributors have taken a firm stand by either presenting hypotheses or suggesting new ways to approach research problems in their fields. The authors describe new models and hypotheses for such complex questions as: Embryos are biological clocks, but how do they keep time? Oncogenes cause many tumors, even though they are, or are related to, normal components of genomes. What is their normal function? Morphogenesis is the acquisition or form by embryos, and it is under strict genetic control. Nevertheless, no gene product yet identified plays a direct role in these cellular movements. Why has it not been found? Molecular Approaches to Supracellular Phenomena will Interest students, scholars, and researchers in developmental biology.
Download or read book Progress in Molecular and Subcellular Biology written by Philippe Jeanteur and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological functions are almost exclusively attributed to macromolecules, i.e. nucleic acids, proteins and polysaccharides. To gain their complete functional activities these biomolecules have to associate with the nuclear matrix, the cytoskeleton and the cell/plasma membranes. It is the aim of this series to discuss actual aspects in the field of structure-associated genetic and epigenetic functional processes. This series of survey reviews fills the gap in structure-associated information flow, and is a vital reference work for scientists in molecular and cell biology.
Download or read book Microbial Interactions written by J.L. Reissig and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbiology has undergone a number of metamorphoses in its relatively brief existence. It has been in approximate succession, morphology, epidemiology, biochemistry, genetics, and molecular biology. It is also becoming a significant parcel of cell surface studies. The one embodiment which has remained elusiv- particularly for bacteriology - is the taxonomic one. This may have been a blessing in disguise because it encouraged microbiologists to deal with the general rather than the particular; promoting a search for unitary explanations, in the manner of Kluyver and van Niel, long before anyone knew about the universality of the genetic code, or could trace the genealogy of enzymes from the study of amino acid substitutions. . This volume is predicated on the idea that deep analogies underly the mech anisms of cellular interaction, and therefore belongs in the unitary tradition of microbiology. It occupies itself with a wide variety of micro-organisms, considering them from vantage points of considerable diversity, ranging from taxonomic irreverence to keen evolutionary awareness, and is concerned with areas which have developed independently of each other.
Download or read book The Social Biology of Microbial Communities written by Institute of Medicine and published by National Academies Press. This book was released on 2013-01-10 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning with the germ theory of disease in the 19th century and extending through most of the 20th century, microbes were believed to live their lives as solitary, unicellular, disease-causing organisms . This perception stemmed from the focus of most investigators on organisms that could be grown in the laboratory as cellular monocultures, often dispersed in liquid, and under ambient conditions of temperature, lighting, and humidity. Most such inquiries were designed to identify microbial pathogens by satisfying Koch's postulates.3 This pathogen-centric approach to the study of microorganisms produced a metaphorical "war" against these microbial invaders waged with antibiotic therapies, while simultaneously obscuring the dynamic relationships that exist among and between host organisms and their associated microorganisms-only a tiny fraction of which act as pathogens. Despite their obvious importance, very little is actually known about the processes and factors that influence the assembly, function, and stability of microbial communities. Gaining this knowledge will require a seismic shift away from the study of individual microbes in isolation to inquiries into the nature of diverse and often complex microbial communities, the forces that shape them, and their relationships with other communities and organisms, including their multicellular hosts. On March 6 and 7, 2012, the Institute of Medicine's (IOM's) Forum on Microbial Threats hosted a public workshop to explore the emerging science of the "social biology" of microbial communities. Workshop presentations and discussions embraced a wide spectrum of topics, experimental systems, and theoretical perspectives representative of the current, multifaceted exploration of the microbial frontier. Participants discussed ecological, evolutionary, and genetic factors contributing to the assembly, function, and stability of microbial communities; how microbial communities adapt and respond to environmental stimuli; theoretical and experimental approaches to advance this nascent field; and potential applications of knowledge gained from the study of microbial communities for the improvement of human, animal, plant, and ecosystem health and toward a deeper understanding of microbial diversity and evolution. The Social Biology of Microbial Communities: Workshop Summary further explains the happenings of the workshop.

Download or read book Dictyostelium written by Richard H. Kessin and published by Cambridge University Press. This book was released on 2001-01-11 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dictyostelia are soil amoebae capable of extraordinary feats of survival, motility, chemotaxis, and development. Characterised by their ability to transform from a single-celled organism into an elaborate assemblage of thousands of synchronously-moving cells, Dictyostelids are often referred to as 'social amoebae', and have been the subjects of serious study since the 1930s. Research in this area has been instrumental in understanding many problems in cellular biology. Beginning with the history of Dictyostelids and discussing each stage of their development, this book considers the evolution of this unique organism, analyses the special properties of the Dictyostelid genome, and presents in detail the methods available, at the time of the book's original publication in 2001, to manipulate their genes. Representing the synthesis of such material and with an emphasis on combining classical experiments with modern molecular findings, this book will be essential for researchers and graduates in developmental and cellular biology.
