Book Description
The formation of various forms of memory involves a series of distinct cellular and molecular mechanisms, many of which are not fully understood. There are highly conserved pathways that are involved in learning, memory, and synaptic plasticity, which is the primary substrate for memory storage. The formation of short-term (across minutes) memory is mediated by local changes in synapses, while long-term (across hours to days) memory storage is associated with activation of transcription and synthesis of proteins that modify synaptic function. Transcription factors, which can either repress or activate transcription, play a vital role in driving protein synthesis underlying synaptic plasticity and memory, whereby protein synthesis provides the necessary building blocks to accommodate structural changes at the synapse that foster memory formation. Recent data implicate several families of transcription factors that appear critically important in the regulation of memory. In this Topic we will focus on the families of transcription factors thus far found to be critically involved in synaptic plasticity and memory formation. These include cAMP response element binding protein (CREB), Rel/nuclear factor B (Rel/NFB), CCAAT enhancer binding protein (C/EBP), and early growth response factor (Egr). In recent years, numerous studies have implicated epigenetic mechanisms, changes in gene activity and expression that occur without alteration in gene sequence, in the memory consolidation process. DNA methylation and chromatin remodeling are critically involved in learning and memory, supporting a role of epigenetic mechanisms. Here we provide more evidence of the importance of DNA methylation, histone posttranslational modifications and the role of histone acetylation and HDAC inhibitors in above mentioned processes.

Book Description
In the genome era, the analysis of gene expression has become a critical requirement in many laboratories. But there has been no comprehensive source of strategic, conceptual, and technical information to guide this often complex task. Transcriptional Regulation in Eukaryotes answers that need. Written by two experienced investigators, Michael Carey and Stephen Smale at the UCLA School of Medicine, and based in part on the Gene Expression course taught at Cold Spring Harbor Laboratory, this book directly addresses all the concerns of a laboratory studying the regulation of a newly isolated gene and the biochemistry of a new transcription factor. This important and unique book is essential reading for anyone pursuing the analysis of gene expression in model systems or disease states.

Neuroepigenomics in Aging and Disease
Author: Raul Delgado-Morales
Publisher: Springer
ISBN: 3319538896
Category : Science
Languages : en
Pages : 520
Book Description
Epigenetic mechanisms (DNA modifications, histone alterations and non-coding RNAs) are crucial for transcriptional regulation and alterations of the “physiological epigenome” are increasingly associated with human diseases. During the last decade the emerging field of neuroepigenomics have started to impact tremendously in areas such learning and memory, addiction or neurodegeneration. This expert volume covers the role of epigenetic molecular mechanism in regulation of central nervous system’s function, one of the most exciting areas of contemporary molecular neuroscience. The book describes the current knowledge on the epigenetic basis of human disease covering the complete lifespan: from neurodevelopment/childhood (Rett Syndrome, Rubinstein-Taybi, autism), adolescence (eating disorders, drug addiction, anxiety), adulthood (depression, schizophrenia, amyotrophic lateral sclerosis, Huntington’s disease) and elderly (Alzheimer’s disease, Parkinson’s disease). The book also covers the three major players on neuroepigenomic mechanisms: histones alterations, DNA modifications and non-coding RNAs, their roles at the molecular and cellular level and the impact of their alterations on neuronal function and behavior. Finally, a special chapter on state-of-the-art technologies helps the reader not only to understand epigenetic driven changes in human cognition and diseases but also the methodology that will help to generate paradigm shifts on our understanding of brain function and the role of the neuroepigenome in human diseases.

Category : Medical
Languages : en
Pages : 258
Book Description
T cells play a vital role mediating adaptive immunity, a specific acquired resistance to an infectious agent produced by the introduction of an antigen. There are a variety of T cell types with different functions. They are called T cells, because they are derived from the thymus gland. This volume discusses how T cells are regulated through the operation of signaling mechanisms. Topics covered include positive and negative selection, early events in T cell receptor engagement, and various T cell subsets.

Chromatin and Gene Regulation
Author: Bryan M. Turner
Publisher: John Wiley & Sons
ISBN: 0865427437
Category : Science
Languages : en
Pages : 312
Book Description
Written in an informal and accessible style, Chromatin and Gene Regulation enables the reader to understand the science of this rapidly moving field. Chromatin is a fundamental component in the network of controls that regulates gene expression. Many human diseases have been linked to disruption of these control processes by genetic or environmental factors, and unravelling the mechanisms by which they operate is one of the most exciting and rapidly developing areas of modern biology. Chromatin is central both to the rapid changes in gene transcription by which cells respond to changes in their environment and also to the maintenance of gene expression patterns from one cell generation to the next. This book will be an invaluable guide to undergraduate and postgraduate students in the biological sciences and all those with an interest in the medical implications of aberrant gene expression.

Learning and Memory
Author: Eric R. Kandel
Publisher:
ISBN: 9781621820918
Category : Medical
Languages : en
Pages : 0
Book Description
We learn and remember information by modifying synaptic connections in the neuronal networks of our brain. Depending on the type of information being stored, these changes occur in different regions and different circuits of the brain. The underlying circuit mechanisms are beginning to be understood. These mechanisms are capable of storing or reconstructing memories for periods ranging up to a lifetime, but they are also error-prone, as memories can be distorted or lost. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology examines important aspects of the neurobiology of learning and memory. Contributors review the various types of memory and the anatomical architectures and specialized cells involved. The induction of synaptic and cell-wide changes during memory encoding, the transcriptional and translational programs required for memory stabilization, the molecular signals that actively maintain memories, and the activation of neural ensembles during memory retrieval are comprehensively covered. The authors also discuss the model organisms and state-of-the-art technologies used to elucidate these processes. This volume will serve as a valuable reference for all neurobiologists and biomedical scientists as well as for cognitive and computational neuroscientists wishing to explore the remarkable phenomena of learning and memory.

Book Description
The story of Nobel Prize–winning discoveries regarding the molecular mechanisms controlling the body’s circadian rhythm. How much of our fate is decided before we are born? Which of our characteristics is inscribed in our DNA? Weiner brings us into Benzer's Fly Rooms at the California Institute of Technology, where Benzer, and his asssociates are in the process of finding answers, often astonishing ones, to these questions. Part biography, part thrilling scientific detective story, Time, Love, Memory forcefully demonstrates how Benzer's studies are changing our world view--and even our lives. Jonathan Weiner, winner of the Pulitzer Prize for The Beak of the Finch, brings his brilliant reporting skills to the story of Seymour Benzer, the Brooklyn-born maverick scientist whose study of genetics and experiments with fruit fly genes has helped revolutionize or knowledge of the connections between DNA and behavior both animal and human.
