Download or read book Neuroprotective Signaling Through Metabotropic Glutamate Receptor 1 written by Andrew Clayton Emery and published by . This book was released on 2011 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metabotropic glutamate receptor 1 (mGlu1) is a G protein-coupled receptor which enhances the hydrolysis of membrane phosphoinositides (PI). Additionally, mGlu1 receptors have been shown to stimulate cytoprotective signaling in the presence of the endogenous ligand glutamate. This goal of the experiments in the following thesis was to (1) characterize the signal transduction pathway through which mGlu1 receptors protect cells expressing these receptors from toxicity. Instead of the classical G protein-mediated (PI) signaling, the following experiments indicate that mGlu1a receptors cause a sustained phosphorylation of ERK that is {beta}-arrestin-1 dependent. This G protein-independent signaling pathway was necessary for protective signaling and was stimulated by glutamate, but not quisqualate, demonstrating ligand bias at this receptor. (2) Therefore, pharmacological and mutational studies were carried out to investigate the molecular basis of this ligand bias. Together, these studies indicate the existence of 3 classes of mGlu1a receptor agonists: (a) unbiased agonists, such as glutamate, which stimulate both signal transduction pathways, (b) biased agonists, such as quisqualate, which only stimulate PI hydrolysis, and (c) agonists which are biased toward sustained ERK phosphorylation and protective signaling. In these studies, glutaric and succinic acid were identified as protection-biased mGlu1a receptor agonists. Further pharmacological studies indicate that quisqualate does not inhibit glutamate-induced protection and glutaric acid fails to inhibit glutamate-induced PI hydrolysis, suggesting the existence of two distinct, non-overlapping agonist binding sites on mGlu1a receptors.
Download or read book FUNCTION AND SIGNAL TRANSDUCTION OF METABOTROPIC GLUTAMATE RECEPTOR 1 IN CEREBELLAR GRANULE CELLS written by Hannah Allysum Hathaway and published by . This book was released on 2014 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finally, in chapter 3, we report that neuroprotective mGlu1 receptor signaling overcomes excitotoxic NMDA receptor signaling. Under pathophysiological conditions excess quantities of glutamate are released into the extracellular space and cause cell death via NMDA receptor-mediated excitotoxicity. Yet, in cerebellar granule cells, application of glutamate increases cell viability via activation of mGlu1 receptors. Here we report that when mGlu1 receptor activity is decreased, either by pharmacological blockade or by reduced receptor expression, glutamate application results in a decrease in granule cell viability that is blocked by antagonism of NMDA receptors.

Download or read book The Metabotropic Glutamate Receptors written by P. Jeffrey Conn and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Metabotropic Glutamate Receptors offers state-of-the-art summaries and reviews of virtually everything known today about metabotropic glutamate receptors (mGluRs), including their molecular biology, pharmacology, anatomical distribution, and physiological and pathological roles. Illuminating the overall role played by this crucial class of receptors in brain function, the book also pinpoints those areas in which there is the greatest continuing need for focused research. Because mGluRs have the potential for participating in virtually all known functions of the central nervous system (CNS), the opportunity now exists to develop pharmacological agents that can potentially alter many brain disease processes by selective interaction with precise CNS functions. With its critical and insightful reviews, The Metabotropic Glutamate Receptors will immediately become your essential key to the development of novel treatment strategies for the widest variety of neurological disorders.
Download or read book Glial Neuronal Signaling written by Glenn I. Hatton and published by Springer Science & Business Media. This book was released on 2004-05-31 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glial Neuronal Signaling fills a need for a monograph/textbook to be used in advanced courses or graduate seminars aimed at exploring glial-neuronal interactions. Even experts in the field will find useful the authoritative summaries of evidence on ion channels and transporters in glia, genes involved in signaling during development, metabolic cross talk and cooperation between astrocytes and neurons, to mention but a few of the timely summaries of a wide range of glial-neuronal interactions. The chapters are written by the top researchers in the field of glial-neuronal signaling, and cover the most current advances in this field. The book will also be of value to the workers in the field of cell biology in general. When we think about the brain we usually think about neurons. Although there are 100 billion neurons in mammalian brain, these cells do not constitute a majority. Quite the contrary, glial cells and other non-neuronal cells are 10-50 times more numerous than neurons. This book is meant to integrate the emerging body of information that has been accumulating, revealing the interactive nature of the brain's two major neural cell types, neurons and glia, in brain function.
Download or read book The Heterogeneity of Cancer Metabolism written by Anne Le and published by Springer. This book was released on 2018-06-26 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic alterations in cancer, in addition to being the fundamental drivers of tumorigenesis, can give rise to a variety of metabolic adaptations that allow cancer cells to survive and proliferate in diverse tumor microenvironments. This metabolic flexibility is different from normal cellular metabolic processes and leads to heterogeneity in cancer metabolism within the same cancer type or even within the same tumor. In this book, we delve into the complexity and diversity of cancer metabolism, and highlight how understanding the heterogeneity of cancer metabolism is fundamental to the development of effective metabolism-based therapeutic strategies. Deciphering how cancer cells utilize various nutrient resources will enable clinicians and researchers to pair specific chemotherapeutic agents with patients who are most likely to respond with positive outcomes, allowing for more cost-effective and personalized cancer therapeutic strategies.
