Download or read book Mechanisms of Transcriptional Control in Phosphate responsive Signaling Pathway of Saccharomyces Cerevisiae written by Xu Zhou and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regulation of gene expression is essential for many biological processes. Binding of transcription factors to DNA is a key regulatory step in the control of gene expression. It is commonly observed that DNA sequences with high affinity for transcription factors occur more frequently in the genome than the instances of genes bound or regulated by these factors. However, the mechanism by which transcription factors selectively identify and regulate these genes was unclear. I utilized the transcriptional control of the phosphate-responsive signaling pathway (PHO) in Saccharomyces cerevisiae as a model system to address this problem.

Download or read book Quantitative Analysis of Nutrient responsive Signal Transduction Pathways in Saccharomyces Cerevisiae written by Jonathan M. Raser and published by . This book was released on 2005 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organisms and their component cells exist in a dynamic and unpredictable environment. Many of these environmental changes are potentially harmful or lethal. It is therefore unsurprising that cells are capable of adaptation to many of these potentially harmful environmental conditions. This adaptation requires both the ability to gather information about the environment, and the ability to convert the information gathered into the appropriate cellular response. Cells have developed specific signal transduction pathways that respond to a specific environmental stimulus and effect a specific, corresponding cellular response. Such signal transduction pathways are quantitative, in that cells do not simply display binary information processing but are capable of more subtle interpretation of different magnitudes of a particular stimulus. In particular, many signaling pathways enable adaptation to changing levels of environmental nutrients by control of cellular gene expression. We employed the single-cell eukaryote Saccharomyces cerevisiae as a model to study several facets of nutrient-responsive signal transduction in a quantitative manner. In the following text, we present our study of the sources of heterogeneity in gene expression in a population of genetically identical cells. In addition, we review recent advances in understanding of heterogeneity or noise in gene expression. Also, we present work characterizing the zinc-responsive signaling pathway in a quantitative manner, and studies uncovering the presence of positive feedback in the phosphate-responsive (PHO) signaling pathway.

Download or read book Yeast Membrane Transport written by José Ramos and published by Springer. This book was released on 2015-12-31 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: This contributed volume reviews the recent progress in our understanding of membrane transport in yeast including both Saccharomyces cerevisiae and non-conventional yeasts. The articles provide a summary of the key transport processes and put these in a systems biology context of cellular regulation, signal reception and homeostasis. After a general introduction, readers will find review articles covering the mechanisms and regulation of transport for various substrates ranging from diverse nutrients to cations, water and protons. These articles are complemented by a chapter on extremophilic yeast, a chapter on the mathematical modelling of ion transport and two chapters on the role of transport in pathogenic yeasts and antifungal drug resistance. Each article provides both a general overview of the main transport characteristics of a specific substrate or group of substrates and the unique details that only an expert working in the field is able to transmit to the reader. Researchers and students of the topic will find this book to be a useful resource for membrane transport in yeast collecting information in one complete volume, which is otherwise scattered across many papers. This might also be interesting for scientists investigating other species in order to compare transport mechanisms with known functions in yeast with the cells on which they work.

Download or read book Molecular Mechanisms Controlling Transmembrane Transport written by Eckhard Boles and published by Springer Science & Business Media. This book was released on 2004-06-16 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: All living cells are strictly separated from their surroundings by a membranous lipid bilayer. Into these membranes a variety of transport proteins are embedded that ensure the uptake and secretion of various molecules and ions. In order to respond properly to a changing nutrient supply or demand, as well as to external stress factors, cells must be able to adapt both amount and activity of the corresponding transporters. This book provides readers with state-of-the-art knowledge on the various regulatory mechanisms that control transmembrane transporter expression, activity and their subcellular localisation.

Download or read book Phosphate Metabolism written by Shaul Massry and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present to our readers the proceedings of the Second International Workshop on Phosphate. A short account of the history of the effort led to the Phosphate Workshops is appro priate and can be of interest to the reader. The idea for Phosphate Workshops was born in the early days of November, 1974. One of us (S. G. M. ) suggested the thought to a group of scientists gathered for a luncheon in one of the attrac tive small restaurants in Weisbaden, Germany. The purpose of the workshop was to bring together interested scientists to discuss the newer developments and the recent advances in the field of phosphate metabolism and the other related minerals. An Organizing Committee made of Shaul G. Massry (USA), Louis V. Avioli (USA), Philippe Bordier (France), Herbert Fleisch (Switzerland), and Eduardo Slatopolsky (USA) was formed. The First Workshop was held in Paris during June 5-6, 1975 and was hosted by Dr. Philippe Bordier. Its proceeding was already published. The Second Workshop took place in Heidelberg during June 28-30, 1976 and was hosted by Dr. Eberhard Ritz. Both of these workshops were extremely successful scientific endeavors, and the need for them was demonstrated by the great interest they generated among the scientific community. The Or ganizing Committee, therefore, decided to continue with the tradi tion to hold additional Workshops annually or every other year.
Download or read book Nutrient Induced Responses in Eukaryotic Cells written by Joris Winderickx and published by Springer Science & Business Media. This book was released on 2004-03-29 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells of all living organisms have the ability to respond to altered nutritional conditions. They have developed mechanisms to sense nutrient availability and to produce appropriate responses, which involve changes in gene expression and the production or degradation of certain enzymes and other proteins. In recent years, the understanding of nutrient-induced signal transduction has greatly advanced and the emerging picture is that nutrient signalling mechanisms evolved early in evolution. This book provides a detailed presentation and comparison of the key nutritional regulatory mechanisms in lower as well as higher eukaryotes, written by recognised experts in this expanding field.
Download or read book RNA Exosome written by Torben Heick Jensen and published by Springer Science & Business Media. This book was released on 2011-06-29 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diversity of RNAs inside living cells is amazing. We have known of the more “classic” RNA species: mRNA, tRNA, rRNA, snRNA and snoRNA for some time now, but in a steady stream new types of molecules are being described as it is becoming clear that most of the genomic information of cells ends up in RNA. To deal with the enormous load of resulting RNA processing and degradation reactions, cells need adequate and efficient molecular machines. The RNA exosome is arising as a major facilitator to this effect. Structural and functional data gathered over the last decade have illustrated the biochemical importance of this multimeric complex and its many co-factors, revealing its enormous regulatory power. By gathering some of the most prominent researchers in the exosome field, it is the aim of this volume to introduce this fascinating protein complex as well as to give a timely and rich account of its many functions. The exosome was discovered more than a decade ago by Phil Mitchell and David Tollervey by its ability to trim the 3’end of yeast, S. cerevisiae, 5. 8S rRNA. In a historic account they laid out the events surrounding this identification and the subsequent birth of the research field. In the chapter by Kurt Januszyk and Christopher Lima the structural organization of eukaryotic exosomes and their evolutionary counterparts in bacteria and archaea are discussed in large part through presentation of structures.

Download or read book Innovative Medicine written by Kazuwa Nakao and published by Springer. This book was released on 2015-10-13 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to innovative medicine, comprising the proceedings of the Uehara Memorial Foundation Symposium 2014. It remains extremely rare for the findings of basic research to be developed into clinical applications, and it takes a long time for the process to be achieved. The task of advancing the development of basic research into clinical reality lies with translational science, yet the field seems to struggle to find a way to move forward. To create innovative medical technology, many steps need to be taken: development and analysis of optimal animal models of human diseases, elucidation of genomic and epidemiological data, and establishment of “proof of concept”. There is also considerable demand for progress in drug research, new surgical procedures, and new clinical devices and equipment. While the original research target may be rare diseases, it is also important to apply those findings more broadly to common diseases. The book covers a wide range of topics and is organized into three complementary parts. The first part is basic research for innovative medicine, the second is translational research for innovative medicine, and the third is new technology for innovative medicine. This book helps to understand innovative medicine and to make progress in its realization.
