Recombinant Protein Production with Prokaryotic and Eukaryotic Cells. A Comparative View on Host Physiology by Otto-Wilhelm Merten,D. Mattanovich,C. Lang,G. Larsson,P. Neubauer,D. Porro,P. Postma,J. Teixeira de Mattos,J.A. Cole Pdf

More then 20 years have passed now since the first recombinant protein producing microorganisms have been developed. In the meanwhile, numerous proteins have been produced in bacteria, yeasts and filamentous fungi, as weIl as higher eukaryotic cells, and even entire plants and animals. Many recombinant proteins are on the market today, and some of them reached substantial market volumes. On the first sight one would expect the technology - including the physiology of the host strains - to be optimised in detail after a 20 year's period of development. However, several constraints have limited the incentive for optimisation, especially in the pharmaceutical industry like the urge to proceed quickly or the requirement to define the production parameters for registration early in the development phase. The additional expenses for registration of a new production strain often prohibits a change to an optimised strain. A continuous optimisation of the entire production process is not feasible for the same reasons.

Recombinant Protein Production with Prokaryotic and Eukaryotic Cells. A Comparative View on Host Physiology by Otto-Wilhelm Merten Pdf

The general field of fundamental and applied biotechnology becomes increasingly important for the production of biologicals for human and veterinary use, by using prokaryotic and eukaryotic microorganisms. The papers in the present book are refereed articles compiled from oral and poster presentations from the EFB Meeting on Recombinant Protein Production with Prokaryotic and Eukaryotic Cells. A Comparative View on Host Physiology, which was organized in Semmering/A from 5th to 8th October 2000. A special feature of this meeting was the comparison of different classes of host cells, mainly bacteria, yeasts, filamentous fungi, and animal cells, which made obvious that many physiological features of recombinant protein formation, like cell nutrition, stress responses, protein folding and secretion, or genetic stability, follow similar patterns in different expression systems. This comparative aspect is by far the point of most interest because such comparisons are rarely done, and if they are done, their results are most often kept secret by the companies who generated them. Audience: Presently, a comparable book does not exist because the compiling of manuscripts from all fields of biotechnology (prokaryotic as well as eukaryotic, up to animal cell biotechnology) is not done in general. This particularity makes this book very interesting for postgraduate students and professionals in the large field of biotechnology who want to get a more global view on the current state of the expression of recombinant biologicals in different host cell systems, the physiological problems associated with the use of different expression systems, potential approaches to solve such difficulties by metabolic engineering or the use of other host cells, and the cooperation between process development and strain improvement, which is crucial for the optimisation of both the production strain and the process. This book should be in every library of an institution/organization involved in biotechnology.

Recombinant protein expression in microbial systems by Eduardo A. Ceccarelli,Germán L. Rosano Pdf

With the advent of recombinant DNA technology, expressing heterologous proteins in microorganisms rapidly became the method of choice for their production at laboratory and industrial scale. Bacteria, yeasts and other hosts can be grown to high biomass levels efficiently and inexpensively. Obtaining high yields of recombinant proteins from this material was only feasible thanks to constant research on microbial genetics and physiology that led to novel strains, plasmids and cultivation strategies. Despite the spectacular expansion of the field, there is still much room for progress. Improving the levels of expression and the solubility of a recombinant protein can be quite challenging. Accumulation of the product in the cell can lead to stress responses which affect cell growth. Buildup of insoluble and biologically inactive aggregates (inclusion bodies) lowers the yield of production. This is particularly true for obtaining membrane proteins or high-molecular weight and multi-domain proteins. Also, obtaining eukaryotic proteins in a prokaryotic background (for example, plant or animal proteins in bacteria) results in a product that lack post-translational modifications, often required for functionality. Changing to a eukaryotic host (yeasts or filamentous fungi) may not be a proper solution since the pattern of sugar modifications is different than in higher eukaryotes. Still, many advances in the last couple of decades have provided to researchers a wide variety of strategies to maximize the production of their recombinant protein of choice. Everything starts with the careful selection of the host. Be it bacteria or yeast, a broad list of strains is available for overcoming codon use bias, incorrect disulfide bond formation, protein toxicity and lack of post-translational modifications. Also, a huge catalog of plasmids allows choosing for different fusion partners for improving solubility, protein secretion, chaperone co-expression, antibiotic resistance and promoter strength. Next, controlling culture conditions like temperature, inducer and media composition can bolster recombinant protein production. With this Research Topic, we aim to provide an encyclopedic account of the existing approaches to the expression of recombinant proteins in microorganisms, highlight recent discoveries and analyze the future prospects of this exciting and ever-growing field.

Aluminium and Alzheimer's Disease by C. Exley Pdf

The subject of aluminium and Alzheimer's disease has been plagued with controversy. This controversy has served to obscure much of the scientific research in this field, and subsequently has obscured the possibility that aluminium is a contributory factor in the aetiology of Alzheimer's disease. This book brings together many of the world's leading scientists researching aluminium and life and contains their critical summaries on the known facts about aluminium toxicity in man and to offer an opinion on the implications of this knowledge on a link between aluminium and Alzheimer's disease. The subject areas of the chapters were chosen to reflect the myriad of ways that aluminium is known to impact upon mammalian physiology and function and range from clinical studies, through animal models of disease to the detailed biochemistry of aluminium toxicity. Chapters are also included on epidemiology and other factors involved in the aetiology of Alzheimer's.This is the first time that this subject has been treated in such a comprehensive manner. The research detailed in each chapter, includes the latest research in the field, it has been critically appraised and this appraisal has been used by each author to present an informed opinion of its relevance to aluminium and Alzheimer's disease. The chapters are much more than reviews; they are a statement of the state of the art and of what the future may hold for research in this field. As a whole they show the high quality of research that has been carried out in our efforts to understand the toxicity of aluminium in man and that we are far away from discounting the possibility that aluminium is a contributory factor in the aetiology of Alzheimer's disease.

Production of Recombinant Proteins by Gerd Gellissen Pdf

While the choices of microbial and eukaryotic expression systems for production of recombinant proteins are many, most researchers in academic and industrial settings do not have ready access to pertinent biological and technical information since it is normally scattered throughout the scientific literature. This book closes the gap by providing information on the general biology of the host organism, a description of the expression platform, a methodological section -- with strains, genetic elements, vectors and special methods, where applicable -- as well as examples of proteins produced with the respective platform. The systems thus described are well balanced by the inclusion of three prokaryotes (two Gram-negatives and one Gram-positive), four yeasts, two filamentous fungi and two higher eukaryotic cell systems -- mammalian and plant cells. Throughout, the book provides valuable practical and theoretical information on the criteria and schemes for selecting the appropriate expression platform, the possibility and practicality of a universal expression vector, and on comparative industrial-scale fermentation, with the production of a recombinant Hepatitis B vaccine chosen as an industrial example. With a foreword by Herbert P. Schweizer, Colorado State University, USA: "As a whole, this book is a valuable and overdue resource for a varied audience. It is a practical guide for academic and industrial researchers who are confronted with the design of the most suitable expression platform for their favorite protein for technical or pharmaceutical purposes. In addition, the book is also a valuable study resource for professors and students in the fields of applied biology and biotechnology."

Recombinant Gene Expression by Paulina Balbas,Argelia Lorence Pdf

Since newly created beings are often perceived as either wholly good or bad, the genetic alteration of living cells impacts directly on a symbolic meaning deeply imbedded in every culture. During the earlier years of gene expression research, te- nological applications were confined mainly to academic and industrial laboratories, and were perceived as highly beneficial since molecules that were previously unable to be separated or synthesized became accessible as therapeutic agents. Such were the success stories of hormones, antibodies, and vaccines produced in the bacterium Escherichia coli. Originally this bacterium gained fame among humans for being an unwanted host in the intestine, or worse yet, for being occasionally dangerous and pathogenic. H- ever, it was easily identified in contaminated waters during the 19th century, thus becoming a clear indicator of water pollution by human feces. Tamed, cultivated, and easily maintained in laboratories, its fast growth rate and metabolic capacity to adjust to changing environments fascinated the minds of scientists who studied and modeled such complex phenomena as growth, evolution, genetic exchange, infection, survival, adaptation, and further on—gene expression. Although at the lower end of the complexity scale, this microbe became a very successful model system and a key player in the fantastic revolution kindled by the birth of recombinant DNA technology.
