Available in PDF, EPUB and Kindle. Book excerpt: In all organs of the body, proteases have critical roles to play both in normal development and functioning and in disease states. The brain is no exception to this, with proteases having emerging roles in synaptic plasticity, memory, neurodegenerative disorders such as Alzheimer’s, Parkinson’s and prion diseases, ischemia and traumatic brain injury, inflammatory and infectious diseases, and tumor progression. Proteases in the Brain brings together a wide range of topics under this central theme and highlights the large number of proteases involved in these normal and disease processes. Proteases in the Brain reviews the role and regulation of proteases in, Alzheimer’s disease, brain ischemia and traumatic brain injury, human glioma, inflammatory and infectious diseases of the central nervous system, metabolism of the prion protein, modulating synaptic activity, multiple sclerosis, neuronal plasticity and memory consolidation, Parkinson’s disease, processing, conversion and inactivation of neuropeptides. Proteases in the Brain is a timely and useful source of information both for those well-versed in the role of proteases in the brain, and for those who are beginning to realize the important role of this family of enzymes in brain function and dysfunction.

Available in PDF, EPUB and Kindle. Book excerpt: Proteolysis is an irreversible posttranslational modification affecting each and every protein from its biosynthesis to its degradation. Limited proteolysis regulates targeting and activity throughout the lifetime of proteins. Balancing proteolysis is therefore crucial for physiological homeostasis. Control mechanisms include proteolytic maturation of zymogens resulting in active proteases and the shut down of proteolysis by counteracting endogenous protease inhibitors. Beyond the protein level, proteolytic enzymes are involved in key decisions during development that determine life and death – from single cells to adult individuals. In particular, we are becoming aware of the subtle role that proteases play in signaling events within proteolysis networks, in which the enzymes act synergistically and form alliances in a web-like fashion. Proteases come in different flavors. At least five families of mechanistically distinct enzymes and even more inhibitor families are known to date, many family members are still to be studied in detail. We have learned a lot about the diversity of the about 600 proteases in the human genome and begin to understand their physiological roles in the degradome. However, there are still many open questions regarding their actions in pathophysiology. It is in this area where the development of small molecule inhibitors as therapeutic agents is extremely promising. Approaching proteolysis as the most important, irreversible post-translational protein modification essentially requires an integrated effort of complementary research disciplines. In fact, proteolytic enzymes seem as diverse as the scientists working with these intriguing proteins. This book reflects the efforts of many in this exciting field of research where team and network formations are essential to move ahead.

This book was released on 2007-05-08 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers seeking problems that offer more hope of success often avoid subjects that seem to be difficult to approach experimentally, or subjects for which experimental results are difficult to interpret. The breakdown part of protein turnover in vivo, particularly in nervous tissue, was such a subject in the past – it was difficult to measure and difficult to explore the mechanisms involved. For factors that influence protein metabolism, it was thought that protein content, function, and distribution are controlled only by the synthetic mechanisms that can supply the needed specificity and response to stimuli. The role of breakdown was thought to be only a general metabolic digestion, elimination of excess polypeptides. We now know that the role of breakdown is much more complex: it has multiple functions, it is coupled to turnover, and it can affect protein composition, function, and synthesis. In addition to eliminating abnormal proteins, breakdown has many modulatory functions: it serves to activate and inactivate enzymes, modulate membrane function, alter receptor channel properties, affect transcription and cell cycle, form active peptides, and much more. The hydrolysis of peptide bonds often involves multiple steps, many enzymes, and cycles (such as ubiquination), and often requires the activity of enzyme complexes. Their activation, modification, and inactivation can thus play an important role in biological functions, with numerous families of proteases participating. The specific role of each remains to be elucidated.

Download or read book Role of Proteases in Cellular Dysfunction written by Naranjan S. Dhalla and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now well known that proteases are found everywhere, in viruses and bacteria as well as in all human, animal and plant cells, and play a role in a variety of biological functions ranging from digestion, fertilization, development to senescence and death. Under physiological conditions the ability of proteases is regulated by endogenous inhibitors. However, when the activity of proteases is not regulated appropriately, disease processes can result, as seen in Alzheimer’s disease, cancer metastasis and tumor progression, inflammation and atherosclerosis. Thus it is evident that there is an absolute need for a tighter control of proteolytic activities in different cells and tissues. Aimed at graduate students and researchers with an interest in cellular proteolytic events, Role of Proteases in Cellular Dysfunctions is the second book on Proteases in this series. The book consists of three parts in specified topics based on current literatures for a better understanding for the readers with respect to their subject-wise interests. The first section of this book covers a brief idea about the neuronal disorders and the involvement of proteases such as calpains, caspases and matrix metalloproteases (MMPs). The second section covers the deadly disease cancer and its relation to ubiquitin-proteasome system, MMPs and serine proteases. The last section is about the role of proteases such as calpains, MMPs and serine protease as well as urokinase type plasminogen activator receptor (uPAR) in causing cardiovascular defects.

Download or read book Brain Tumor Invasion written by Tom Mikkelsen and published by Wiley-Liss. This book was released on 1998-05-05 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain Tumor Invasion Biological, Clinical, and Therapeutic Considerations Edited by Tom Mikkelsen Rolf Bjerkvig Ole Didrik Laerum Mark L. Rosenblum Recent advances in molecular biology have given us profound new insights into the behavior of primary brain tumors. Not only are such tumors more diffuse in their infiltration of brain tissue and therefore less amenable to surgery than brain tumors originating elsewhere in the body—it now appears that the central nervous system and the normal brain itself constitute a biological environment conducive to the uncontrolled spread of primary tumors. Brain Tumor Invasion is the first comprehensive reference devoted to the invasive behavior of primary brain tumors. It examines the biological mechanisms responsible for the increased ability of gliomas to metastasize in the central nervous system, and discusses the role of chemical carcinogens, growth factors, oncogenes, and tumor suppressors in the progression of such metastases. This book surveys the latest research in the field, reviews present and future prospects of anti-invasive brain tumor therapy, and even translates preclinical trials and other research results into potential new therapies. The material is divided into five main categories: Developmental biology and molecular neuro-oncology Pathological and clinical features of malignant brain tumors Models for the study of brain tumor invasion in vivo and in vitro Mechanisms of invasion New therapeutic strategies Brain Tumor Invasion offers dozens of maps and photographs that illustrate topics under discussion. This in-depth introduction to one of the most difficult problems in the management of brain tumors is indispensable to neuro-oncologists involved in brain tumor research and therapy. It is also useful to researchers in cancer biology, neuroscience, cell biology, and molecular genetics.
Download or read book Handbook of Proteolytic Enzymes Volume 1 written by Alan J. Barrett and published by Elsevier. This book was released on 2012-12-02 with total page 1182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Proteolytic Enzymes, Second Edition, Volume 1: Aspartic and Metallo Peptidases is a compilation of numerous progressive research studies on proteolytic enzymes. This edition is organized into two main sections encompassing 328 chapters. This handbook is organized around a system for the classification of peptidases, which is a hierarchical one built on the concepts of catalytic type, clan, family and peptidase. The concept of catalytic type of a peptidase depends upon the chemical nature of the groups responsible for catalysis. The recognized catalytic types are aspartic, cysteine, metallo, serine, threonine, and the unclassified enzymes, while clans and families are groups of homologous peptidases. Homology at the level of a family of peptidases is shown by statistically significant relationship in amino acid sequence to a representative member called the type example, or to another member of the family that has already been shown to be related to the type example. Each chapter discusses the history, activity, specificity, structural chemistry, preparation, and biological aspects of the enzyme. This book will prove useful to enzyme chemists and researchers.
