Download or read book Elucidation of a Proteolytic Mechanism Required for Kaposi s Sarcoma associated Herpesvirus Replication written by Alan Brown Marnett and published by . This book was released on 2005 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herpesviruses represent one of the most prevalent human pathogens worldwide. Infection results in a number of diseases ranging from cold sores to cancer. Yet despite the large clinical variation in disease states, the proteins expressed during the lytic cycle of all herpesviruses are highly conserved. A maturational serine protease is expressed late in viral replication and is required for production of properly assembled infectious progeny. In vitro structural and functional analysis has revealed the enzyme possesses a novel protein fold and is activated by dimerization. However, the mechanism of regulation of the enzyme both at a molecular level and in the context of viral replication is unknown. Positional scanning synthetic combinatorial libraries were used to define the substrate specificity of the protease encoded by Kaposi's Sarcoma-associated herpesvirus (KSHV). The strict specificity observed was used to guide the design and synthesis of a peptidyl-diphenylphosphonate inhibitor targeting the active site of the enzyme. Covalent modification of the active site serine of the enzyme by the transition-state analog inhibitor dramatically shifted the equilibrium toward dimeric enzyme illustrating the intimate communication between the spatially separate active sites and dimer interface of the protease. To elucidate the mechanism of stabilization and activation during catalysis, structural analysis was performed on purely monomeric (M197D), purely dimeric (inhibited) and an equilibrium mixture (uninhibited wild-type) by circular dichroism and nuclear magnetic resonance. A massive conformational change was observed upon loss of dimerization in which helices 5 and 6, at the interface and active site, respectively, become disordered, which destabilizes essential catalytic components. A disulfide bond was engineered into the protease at helix 6 that prevented the conformational change and subsequent inactivation of the enzyme. Addition of oxidant or reductant reversibly recovered or abolished enzymatic activity, respectively, even in a monomeric variant of the protease. A reduction in viral replication similar to currently available therapies targeting the viral polymerase was observed upon treatment of reactivated KSHV with the protease inhibitor. The work not only validated the virally-encoded protease as a potential therapeutic target, but also presented a mechanism by which protease inhibition may occur in vivo .

Download or read book Heparanase written by Israel Vlodavsky and published by Springer Nature. This book was released on 2020-04-09 with total page 871 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by internationally recognized leaders in Heparanase biology, the book’s eight chapters offer an opportunity for scientists, clinicians and advanced students in cell biology, tumor biology and oncology to obtain a comprehensive understanding of Heparanase’s multifaceted activities in cancer, inflammation, diabetes and other diseases, as well as its related clinical applications. Proteases and their involvement in cancer progression have been well addressed and documented; however, the emerging premise presented within this book is that Heparanase is a master regulator of aggressive cancer phenotypes and crosstalk with the tumor microenvironment. This endoglycosidase contributes to tumor-mediated remodeling of the extracellular matrix and cell surfaces, augmenting the bioavailability of pro-tumorigenic and pro-inflammatory growth factors and cytokines that are bound to Heparan sulfate. Compelling evidence ties Heparanase with all steps of tumor progression including tumor initiation, growth, angiogenesis, metastasis, and chemoresistance, supporting the notion that Heparanase is an important contributor to the poor outcome of cancer patients and a validated target for therapy. Unlike Heparanase, heparanase-2, a close homolog of Heparanase, lacks enzymatic activity, inhibits Heparanase, and regulates selected genes that promote normal differentiation and tumor suppression. Written by internationally recognized leaders in Heparanase biology, this volume presents a comprehensive understanding of Heparanase’s multifaceted activities in cancer, inflammation, diabetes and other diseases, as well as its related clinical applications to scientists, clinicians and advanced students in cell biology, tumor biology and oncology.
Download or read book Transmembrane Signaling Protocols written by Hydar Ali and published by Springer Science & Business Media. This book was released on 2008-02-05 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The previous edition of Transmembrane Signaling Protocols was published in 1998. Since then the human genome has been completely sequenced and new methods have been developed for the use of microarrays and proteomics to analyze global changes in gene expression and protein profiles. These advances have increased our ability to understand transmembrane signaling processes in much greater detail. They have also simultaneously enhanced our ability to determine the role of a large number of newly identified molecules in signaling events. In addition, novel video microscopy methods have been developed to image transmembrane signaling events in live cells in real time. In view of these major advances, it is time to update the previous edition. Because of the success of that volume, we have chosen to keep the essential character of the book intact. Introductory chapters from experts have been included to provide overall perspective and an overview of recent advances in signal transduction pathways. The individual chapters now include comp- hensive detailed methods, studies in genetically tractable systems, fluorescence microscopy in live single cells, ex vivo analysis of primary cells from tra- genic mice, as well as genomic and proteomic approaches to the analysis of transmembrane signaling events. We would like to express our deep gratitude to the coauthors of this publi- tion. We hope that Transmembrane Signaling Protocols, Second Edition will serve as a valuable resource for future progress in the study of signal transd- tion pathways.
Download or read book Human Herpesviruses written by Yasushi Kawaguchi and published by Springer. This book was released on 2018-06-12 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces and reviews several topics for each human herpesvirus. One of the most important features of the book is that it covers aspects of both basic research and clinical medicine. Herpesviridae, a family of double-strand DNA viruses, has unique biological features by which these viruses establish latency after primary infection and reactivate in later life. Nine human herpesviruses are known so far, and each of them causes a variety of diseases in both primary infection and reactivation. Since the discovery of each human herpesvirus, an abundance of findings related to them has accumulated in basic research and clinical medicine. However, the vast majority of biological features is still masked in mystery. Furthermore, a strategy of treatment and prevention has not yet been established for most human herpesviruses. A wide range of readers will be interested in this volume with its treatment of problematic points and latest findings in the field.

This book was released on 2019-11-09 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book elaborates on drug delivery targeting via intracellular delivery, specifically through the Receptor Mediated Endocytosis (RME) approach, due to the involvement of cellular receptors in various grave diseases. Targeted delivery relies on two basic approaches, passive and active targeting. While passive targeting approaches have shown great promise, the improved selectivity achieved with active targeting approaches has resulted in significantly higher efficacy. Interestingly there are numerous strategies for active targeting, many of which are already highlighted in , Targeted Drug Delivery: Concepts and Applications. Nevertheless an exciting and practical strategy for active targeting, which could enable high intracellular delivery, is through exploitation of RME. Cells in the body express receptors to enable various physiological and biochemical processes. As a result, many of these receptors are overexpressed in pathological conditions, or newer receptors expressed due to defective cellular functioning. RME is based on exploitation of such receptors to achieve intracellular delivery. While targeted delivery can have manifold applications, in this book we focus on two major and challenging therapeutic areas; i) Cancer and ii) Infectious Diseases. Targeted Intracellular Drug Delivery by Receptor Medicated Endocytosis discusses the major receptors that are useful for targeted delivery for these afflictions. A major section of this book is dedicated to details regarding their occurrence and location, the recognition domain of the receptor, structure activity relationship of substrate /ligand for selective binding, ligands explored, antagonists for ligand binding and relevance of these aspects for therapy of cancer and infectious diseases. These facets are elucidated with the help of specific examples from academic research and also emphasize commercial products, wherever relevant. In vitro cellular models relied on for assessing receptor mediated cellular targeting and in vivo models depicting clinical efficacy are focused on in a separate section. Finally, we briefly discuss the regulatory and toxicity issues that may be associated specifically with the RME approach of intracellular drug delivery.
Download or read book Epstein Barr Virus Volume 2 written by Christian Münz and published by Springer. This book was released on 2015-10-01 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epstein Barr virus (EBV) was discovered as the first human tumor virus around 50 years ago. Since its discovery in Burkitt’s lymphoma it has been associated with various other malignancies, infectious mononucleosis and even autoimmune diseases. The two book volumes on EBV summarize the first 50 years of research on this tumor virus, starting with historical perspectives on discovery, oncogenicity and immune control, reviewing the role that the virus plays in the various associated diseases and concluding with a discussion on how the immune system keeps persistent EBV infection under control in healthy EBV carriers and can be used to treat EBV associated diseases. The respective 32 chapters are written by international experts from three continents for health care providers, biomedical researchers and patients that are affected by EBV. The assembled knowledge should help to understand EBV associated diseases better and to develop EBV specific vaccination in the near future.
