publisher: Springer, published: 2009-12-22 ASIN: 9048126487 EAN: 9789048126484 sales rank: 2970132 Over a decade ago, a small cellular protein of 12 kDa, with 18% homology to the well-known ubiquitin protein, was co-discovered and termed Small Ubiquitin-like Modifier, or SUMO. Sumoylation is a post-translational modification that utilizes SUMO as the modifier group covalently attached to target substrates. This state-of-the art review on the sumoylation system deals with protein modification as it pertains to regulation of diverse cellular functions. Each chapter has been written by a leading researcher and covers the role of sumoylation in fundamental biochemical activities (transcription, RNA processing, chromatin remodelling, DNA repair, nucleocytoplasmic transport, ion channel regulation, and metabolic pathways). The text also examines the part sumoylation plays in critical cellular processes such as mitosis, meiosis, differentiation, senescence, and apoptosis. Lastly, the emerging role of sumoylation in specific diseases, including cancer and diabetes as well as neurodegenerative ones, is explored with an emphasis on defining molecular mechanisms that may provide new targets for treatment or prevention. While SUMO was discovered more than 10 years ago, this is still a relatively young field, and much remains to be discovered about the biochemical and biological properties of this modification system. In just the last few years, it has become clear that sumoylation modifies hundreds of cellular proteins, and there has been increased appreciation for the breadth of cellular functions that are impacted by this post-translational modification. |

by: Stephen Cooper publisher: Academic Press, published: 1991-03-12 ASIN: 0121879054 EAN: 9780121879051 sales rank: 3001800 How does a bacterial cell grow during the division cycle? This question is answered by the codeveloper of the Cooper-Helmstetter model of DNA replication. In a unique analysis of the bacterial division cycle, Cooper considers the major cell categories (cytoplasm, DNA, and cell surface) and presents a lucid description of bacterial growth during the division cycle. The concepts of bacterial physiology from Ole Maaløe's Copenhagen school are presented throughout the book and are applied to such topics as the origin of variability, the pattern of DNA segregation, and the principles underlying growth transitions. The results of research on E. coli are used to explain the division cycles of Caulobacter, Bacilli, Streptococci, and eukaryotes. Insightful reanalysis highlights significant similarities between these cells and E.coli. With over 25 years of experience in the study of the bacterial division cycle, Cooper has synthesized his ideas and research into an exciting presentation. He manages to write a comprehensive volume that will be of great interest to microbiologists, cell physiologists, cell and molecular biologists, researchers in cell-cycle studies, and mathematicians and engineering scientists interested in modeling cell growth. Key Features * Written by one of the codiscoverers of the Cooper-Helmstetter model * Applies the results of research on E. coli to other groups, including Caulobacter, Bacilli, Streptococci, and eukaryotes; the Caulobacter reanalysis highlights significant similarities with the E. coli system * Presents a unified description of the bacterial division cycle with relevance to eukaryotic systems * Addresses the concepts of the Copenhagen School in a new and original way |

publisher: Springer, published: 2010-03-15 ASIN: 9048133025 EAN: 9789048133024 sales rank: 2562519 In 1890 a case of myxedema was treated in Lisbon by the implantation of a sheep thyroid gland with the immediate improvement in the patient’s condition. A few years later, medications for the then ill-explained condition of the menopause included tablets made from cow ovaries. In the first quarter of the 20th century the identification of vitamin D, and its sunlight driven production in skin, paved the way to the elimination of rickets as a major medical problem. Twenty years or so later, Sir Vincent Wigglesworth established the endocrine basis of developmental moulting in insects, arguably the most commonly performed animal behaviour on Planet Earth. A paradigm that would unify these disparate observations arose between 1985 and 1987 beginning with the identification of the glucocorticoid receptor and the nuclear receptor super-family. What follows is a timely and positive manifestation of the capacity, productivity and value of international human scientific endeavour. Based on intrigue, lively competition and cooperation a global effort has rapidly fostered a school of biology with widespread ramifications for the understanding of metazoan animals, the human condition and the state of the planet. This book is the first this century to try and capture the spirit of this endeavour, to depict where the field is now and to identify some of the challenges and opportunities for the future. |

publisher: Springer, published: 2010-12-07 ASIN: 3642078583 EAN: 9783642078583 sales rank: 3859324 The generality and quantitative extent of alternative splicing have only now begun to be fully appreciated. The first draft of the complete human genome led to the surprisingly low figure of about 32,000 genes. The extensive use of alternative splicing and its consequences in terms of coding capacity could account for this discrepancy and help fill the complexity gap between the genome and the proteome. After a computer-based assessment of the frequency of alternative splicing, this book addresses mechanistic aspects followed by examples of its involvement in important cellular processes. Finally, it raises the possibility of artificial modulation of alternative splicing by antisense nucleotides. |

publisher: Springer, published: 2001-12-01 ASIN: 0306466805 EAN: 9780306466809 sales rank: 2767085 Advances in molecular biology and recombinant DNA technology have accelerated progress in many fields of life science research, including gene therapy. A large number of genetic engineering approaches and methods are readily available for gene cloning and therapeutic vector construction. Significant progress is being made in genomic, DNA sequencing, gene expression, gene delivery and cloning. Thus gene therapy has already shown that it holds great promise for the treatment of many diseases and disorders. In general it involves the delivery of recombinant genes or transgenes into somatic cells to replace proteins with a genetic defect or to transfer with the pathological process of an illness. The viral and non-viral delivery systems may hold the potential for future non-invasive, cost-effective oral therapy of genetically-based disorders. Recent years have seen considerable progress in the discovery and early clinical development of a variety of gene therapeutic products. The availability, validation, and implementation of gene therapeutic products has also enabled success in testing and evaluation. New challenges will need to be overcome to ensure that products will also be successful in later clinical development and ultimately for marketing authorisation. These new challenges will include improvements in delivery systems, better control of in-vivo targeting, increased level transduction and duration of expression of the gene, and manufacturing process efficiencies that enable reduction in production costs. Perhaps profound understanding of regulated gene design may result in innovative bioproducts exhibiting safety and efficacy profiles that are significantly superior to those achieved by the use of naturally occurring genes. This procedure may contribute considerably to fulfilling standards set by regulatory authorities. This book provides an overview of the current advances in the field of gene therapy and the methods that are being successfully applied in the manufacture of gene therapeutic products, and hopefully will stimulate further progress and advancement in this field to meet the ever-increasing demands. |

publisher: Springer, published: 2008-12-02 ASIN: 1402092814 EAN: 9781402092817 sales rank: 2987655 Photoprotection, Photoinhibition, Gene Regulation, and Environment examines the processes whereby plants monitor environmental conditions and orchestrate their response to change, an ability paramount to the life of all plants. “Excess light”, absorbed by the light-harvesting systems of photosynthetic organisms, is an integrative indicator of the environment, communicating the presence of intense light and any conditions unfavorable for growth and photosynthesis. Key plant responses are photoprotection and photoinhibition. In this volume, the dual role of photoprotective responses in the preservation of leaf integrity and in redox signaling networks modulating stress acclimation, growth, and development is addressed. In addition, the still unresolved impact of photoinhibition on plant survival and productivity is discussed. Specific topics include dissipation of excess energy via thermal and other pathways, scavenging of reactive oxygen by antioxidants, proteins key to photoprotection and photoinhibition, peroxidation of lipids, as well as signaling by reactive oxygen, lipid-derived messengers, and other messengers that modulate gene expression. Approaches include biochemical, physiological, genetic, molecular, and field studies, addressing intense visible and ultraviolet light, winter conditions, nutrient deficiency, drought, and salinity. |
