Download or read book Photoaffinity Labeling Studies on a Promoter of Dendritic Spine Formation written by Kevin Sibucao and published by . This book was released on 2017 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The small molecule BTA-EG4 has been shown to be a promoter of dendritic spine formation. The mechanism behind this phenomenon, however, is not well understood. The work in this dissertation is motivated by this gap in knowledge. The first part of this dissertation focuses on photoaffinity labeling studies to identify the cellular targets of BTA-EG4. Chapter 1 provides a summary of Alzheimer's disease, the rational design of BTA-EG4, and methods to determine targets of small molecules. In Chapter 2, the synthesis of a BTA-EG4-based photoaffinity labeling probe and photodegradation studies are presented. Kinetic studies demonstrate that the probe photolyzes rapidly under UV light. In Chapter 3, photoaffinity labeling studies and subsequent protein identification experiments are reported. Competition experiments with the photoaffinity labeling probe and BTA-EG4 demonstrate that the probe labels a 55-kDa protein specifically. Tandem mass spectrometry revealed that the 55-kDa protein is the actin binding protein fascin 1. The second part of this dissertation focuses on the major protein identified from photoaffinity labeling studies, fascin 1. Chapter 4 provides a brief survey of the structure and function of fascin 1. In Chapter 5, characterizations of the interaction between BTA-EG4 and fascin 1 are reported. Isothermal titration calorimetry confirms the physical binding between fascin 1 and BTA-EG6, a BTA-EG4 analog. Slow speed sedimentation assays reveal that BTA-EG4 does not affect the actin-bundling activity of fascin 1. However, GST pull-down experiments show that BTA-EG4 inhibits the binding of fascin 1 with the GTPase Rab35. In addition, this work demonstrates that BTA-EG4 may be mechanistically distinct from the known fascin inhibitor G2.
Download or read book Integrins and Ion Channels written by Andrea Becchetti and published by Springer Science & Business Media. This book was released on 2010-12-28 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interdisciplinarity is more often invoked than practised. This is hardly surprising, considering the daunting vastness of modern biology. To reach a satisfactory understanding of a complex biological system, a wide spectrum of conceptual and experimental tools must be applied at different levels, from the molecular to the cellular, tissue and organismic. We believe the multifaceted regulatory interplay between integrin receptors and ion channels offers a rich and challenging field for researchers seeking broad biological perspectives. By mediating cell adhesion to the extracellular matrix, integrins regulate many developmental processes in the widest sense (from cell choice between differentiation and proliferation, to tissue remodeling and organogenesis). Rapidly growing evidence shows that frequent communication takes place between cell adhesion receptors and channel proteins. This may occur through formation of multiprotein membrane complexes that regulate ion fluxes as well as a variety of intracellular signaling pathways. In other cases, cross talk is more indirect and mediated by cellular messengers such as G proteins. These interactions are reciprocal, in that ion channel stimulation often controls integrin activation or expression. From a functional standpoint, studying the interplay between integrin receptors and ion channels clarifies how the extracellular matrix regulates processes as disparate as muscle excitability, synaptic plasticity and lymphocyte activation, just to mention a few. The derangement of these processes has many implications for pathogenesis processes, in particular for tumor invasiveness and some cardiovascular and neurologic diseases. This book provides a general introduction to the problems and methods of this blossoming field.

Download or read book Histamine in the brain written by Jian-Sheng Lin and published by Frontiers Media SA. This book was released on 2015-03-18 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain aminergic pathways are organized in parallel and interacting systems, which support a range of functions, from homoeostatic regulations to cognitive, and motivational processes. Despite overlapping functional influences, dopamine, serotonin, noradrenaline and histamine systems provide different contributions to these processes. The histaminergic system, long ignored as a major regulator of the sleep-wake cycle, has now been fully acknowledged also as a major coordinator of attention, learning and memory, decision making. Although histaminergic neurons project widely to the whole brain, they are functionally heterogeneous, a feature which may provide the substrate for differential regulation, in a region-specific manner, of other neurotransmitter systems. Neurochemical preclinical studies have clearly shown that histamine interacts and modulates the release of neurotransmitters that are recognized as major modulators of cognitive processing and motivated behaviours. As a consequence, the histamine system has been proposed as a therapeutic target to treat sleep-wake disorders and cognitive dysfunctions that accompany neurodegenerative and neuroinflammatory pathologies. Last decades have witnessed an unexpected explosion of interest in brain histamine system, as new receptors have been discovered and selective ligands synthesised. Nevertheless, the complete picture of the histamine systems fine-tuning and its orchestration with other pathways remains rather elusive. This Research Topic is intended to offer an inter-disciplinary forum that will improve our current understanding of the role of brain histamine and provide the fundamentals necessary to drive innovation in clinical practice and to improve the management and treatment of neurological disorders.

Download or read book New Developments in Lipid Protein Interactions and Receptor Function written by K.W.A. Wirtz and published by Springer. This book was released on 2012-10-24 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: A NATO Advanced Study Institute on "New Developments in Lipid-Protein Interactions and Receptor Function" was held on the Island of Spetsai, Greece, from August 16-27, 1992. This Institute was organized to bring together researchers in the field of membrane organization and dynamics with those actively involved in studies on receptor function, signal transduction mechanisms and gene regulation. 2 Presentations and discussions focussed on the regulation of intracellular Ca +-levels, on the second messengers derived from inositol lipids and on the specific phospholipase C isozymes involved in these processes. A major focus was on G-proteins and the effect of lipid anchors on their function. These principles of regulation were further discussed in the context of receptors for acetylcholine, lysophosphatidic acid and low-density lipoproteins. In addition, various aspects of the genomic regulation of cell growth and differentiation by transcription factors were presented. These topics were put into perspective by discussing the most recent developments in lipid-protein interactions, protein insertion into membranes, membrane lipid organization and lipid dynamics as mediated by phospholipid transfer proteins. This book presents the content of the major lectures and a selection of the most relevant of the most important topics posters. These proceedings offer a comprehensive account presented during the course of the Institute. The book is intended to make these proceedings accessible to a large audience.
Download or read book Vasopressin and Oxytocin written by Hans H. Zingg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides a comprehensive overview of recent advances in the field of vasopressin and oxytocin. In the summer of 1997, scientists from over 20 countries congregated in Montreal for the 1997 World Congress of Neurohypophysial Hormones, a conference that united the fields of vasopressin, neurohypophysis and oxytocin in a single joint meeting that gave rise to the present book. The organization of a joint meeting was prompted by several recent developments. Specifically the molecular characterization of the vasopressin/oxytocin receptor family made it mandatory to adopt an integrated view and to discuss the vasopressin/oxytocin ligand/receptor family as a whole. To ensure em phasis on novelty, the conference focused on advances made over the last two years and also included important contributions by scientists that had not previously been associated with the vasopressin/oxytocin field. Vasopressin and oxytocin are two neurohormones that exert a wide spectrum of cen tral and peripheral actions. Accordingly, the vasopressin/oxytocin field embraces a large number of different domains, ranging from neuroscience, endocrinology, and oncology to renal, reproductive, and cardiovascular physiology and pathology.
Download or read book G Protein Coupled Receptors written by Jesus Giraldo and published by Royal Society of Chemistry. This book was released on 2011-08-16 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: G protein-coupled receptors (GPCRs) are the largest family of cell-surface receptors, with more than 800 members identified thus far in the human genome. They regulate the function of most cells in the body, and represent approximately 3% of the genes in the human genome. These receptors respond to a wide variety of structurally diverse ligands, ranging from small molecules, such as biogenic amines, nucleotides and ions, to lipids, peptides, proteins, and even light. Ligands (agonists and antagonists) acting on GPCRs are important in the treatment of numerous diseases, including cardiovascular and mental disorders, retinal degeneration, cancer, and AIDS. It is estimated that these receptors represent about one third of the actual identified targets of clinically used drugs. The determination of rhodopsin crystal structure and, more recently, of opsin, 1 and 2 adrenergic and A2A adenosine receptors provides both academia and industry with extremely valuable data for a better understanding of the molecular determinants of receptor function and a more reliable rationale for drug design. GPCR structure and function constitutes a hot topic. The book, which lies between the fields of chemical biology, molecular pharmacology and medicinal chemistry, is divided into three parts. The first part considers what receptor structures tell us about the mechanism of receptor activation. Part II focuses on receptor function. It discusses what the data from biophysical and mutational studies, and the analysis of the interactions of the receptor with ligands and regulator proteins, tell us about the process of signal transduction. The final part, on modelling and simulation, details new insights on the link between structure and mechanism and their implications in drug design.
