Book excerpt: We constructed two protein-protein interaction networks from proteins involved in Alzheimer's disease. Mapping gene expression data to one of the networks identified the MAPK/ERK pathway and clathrin-mediated receptor endocytosis (CME) as key loci of altered gene expression in Alzheimer's. The MAPK/ERK pathway is a critical component of learning and memory. CME affects production of the amyloid-beta peptide. We then used the network models plus additional data to identify potential non-coding SNPs that could affect gene expression. Three SNPs near the transcription start site of the transferrin gene had minor alleles frequencies that differed in Alzheimer's patients versus controls. We then used systematic perturbations of the networks to model the effects of multiple interacting variants. The networks responded in an unexpected manner to multiple node or edge removals. Node and edges with lesser individual effects rose in importance in the networks as they were degraded. This suggests that Alzheimer's-associated genes could be generated by a more random process than expected, and that proteins that initially appear unimportant may play a more significant role in pathogenesis.

This book was released on 2018-09-19 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alzheimer’s Disease (AD) is the product of the slow and progressive degenerative alteration that develops in the adult brain and can remain asymptomatic for a considerable time before cognitive deficits becomes evident. The main challenge for researchers is to identify markers of this degenerative process, and, in this sense, data has been generated through experiments bringing to light new mechanisms and hypothesis to explain its pathophysiology. This book is a review of recent studies in AD molecular biology. Chapters explain various facets of AD, which include animal models, morphological changes, membrane composition, amyloidogenic peptides, intracellular transport systems, and the role of oxidative stress and calcium deregulation. Readers will understand the molecular mechanisms behind AD and therefore broaden their perspective on this neurodegenerative disease and its progression.

Available in PDF, EPUB and Kindle. Book excerpt: Genes, Environment and Alzheimer's Disease discusses the role that activities such as exercise can play in cardiovascular health, while also highlighting the fact that the last 10 years have brought great discoveries in the strong environmental component of brain disorders, neurodegeneration, and cognitive decline. It is now clear that brain insult is an environmental risk factor for AD, while on the other hand, lifestyle components such as exercise and level of education may play a protective role, delaying the onset and/or severity of the disease. Evidence from experiments in rodent models of Alzheimer’s disease contributes major insight into the molecular mechanisms by which the environment plays its role in AD. Additionally, there are diseases related to lifestyle that may lead to AD. This volume reviews new discoveries related to all these factors, serving as a translational tool for clinicians and researchers interested in genetic and environmental risk factors for the disease. Provides the first volume to link genetic and environmental risk factors for Alzheimer’s disease and dementia Aids researchers and clinicians in understanding the basic mechanisms of Alzheimer’s disease and cognitive decline Brings the basic science and clinical perspectives together in a single volume, facilitating translational possibilities Includes a range of molecular to behavioral components assembled into a single volume that creates an excellent resource for basic and clinical neuroscientists

Available in PDF, EPUB and Kindle. Book excerpt: Alzheimer's Disease (AD) is a devastating neurodegenerative disorder affecting all tissues and cell types of brain leading to emotional dysregulation and cognitive dysfunction. From genome-wide association studies (GWAS), to date we have identified forty-two genome-wide significant genes for AD that influence overall disease risk or endophenotypes, including neuroimaging and gene expression profiles. Nevertheless, the currently known AD genes do not account for a significant proportion of the heritability of disease risk, implying the existence of many weak-effect variants in potentially thousands of genes as drivers of AD outcomes. This genetic architecture, composed of many small effects, is partly due to the complexity of molecular interaction networks, where the influence of individual genetic variants is attenuated by overlapping molecular pathways that are tuned by evolution for robustness. Thus, overcoming the limitations of GWAS for dissecting the mechanisms of AD requires methods to identify disease pathways that are enriched for weak genetic effects. Network-based functional prediction (NBFP) methods use machine learning in gene interaction networks to robustly learn pathways containing risk genes, which augments the raw statistical signal from GWAS with biological prior knowledge encoded in a tissue-specific gene network. NBFP methods have several benefits, including their robustness to statistical noise over raw GWAS statistics and they enable nomination of functionally relevant candidate genes that do not themselves carry risk polymorphisms. However, most NBFP methods are currently limited to single tissues, which is not optimal for complex disorders like AD that involve many functionally distinct cell types and brain regions. Moreover, there are now multiple studies of AD endophenotypes, including brain-region specific gene expression and whole-brain neuroimaging, both paired with genotypes, and single-cell gene expression data. Thus, there is an additional need for integrative tools that combine disparate data sources to nominate candidate genes for distinct pathophysiological processes. In this work, we developed new methods to rank candidate genes based on multiple disease-relevant networks and to combine gene rankings arising from multiple sources, including NBFP, imaging GWAS, and gene expression. In our first study, we applied NBFP to systematically rank AD-risk genes in the hippocampus and amygdala and developed a novel combined scoring method to integrate these scores with GWAS associations for low hippocampal and amygdalar volume in patients with AD. Our method nominated a novel set of region-specific candidate genes primarily involved in maintaining the stability of the synapse and regulating excitotoxicity. In our second study, we developed a multi-network-based functional prediction (mNBFP) to allow multiple source networks. Using three brain-cell-specific networks, our mNBFP approach outperformed single-network approaches in training performance and achieved high concordance with recently published AD-GWAS associations. In our third and final study we integrated our multi-network NBFP and combined scoring approaches with single-cell gene expression and the Library of Integrated Network-based Cellular Signatures (LINCS) database to identify potential drug repositioning candidates for AD. We identified the protein AP1B1 as having strong potential to target an early-AD gene expression signature, which may yield a novel mechanism for early therapeutic intervention.

This book was released on 2004-12-17 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand Alzheimer's disease (AD) is one of the major thrusts of present-day clinical research, strongly supported by more fimdamental cellular, biochemical, immunological and structural studies. It is these latter that receive attention within this book. This compilation of 20 chapters indicates the diversity of work currently in progress and summarizes the current state of knowledge. Experienced authors who are scientifically active in their fields of study have been selected as contributors to this book, in an attempt to present a reasonably complete survey of the field. Inevitably, some exciting topics for one reason or another have not been included, for which we can only apologize. Standardization of terminology is often a problem in science, not least in the Alzheimer field; editorial effort has been made to achieve standardization between the Chapters, but some minor yet acceptable personal / author variation is still present, i. e. P-amyloid/amyloid-P; Ap42/Apl-42/APi. 42! The book commences with a broad survey of the contribution that the range of available microscopical techniques has made to the study of Alzheimer's amyloid plaques and amyloid fibrillogenesis. This chapter also serves as an Introduction to the book, since several of the topics introduced here are expanded upon in later chapters. Also, it is significant to the presence of this chapter that the initial discovery of brain plaques, by Alois Alzheimer, utilized light microscopy, a technique that continues to be extremely valuable in present-day AD research.

This book was released on 2021-07-23 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex and Gender Differences in Alzheimer’s Disease: The Women’s Brain Project offers for the first time a critical overview of the evidence documenting sex and gender differences in Alzheimer’s disease neurobiology, biomarkers, clinical presentation, treatment, clinical trials and their outcomes, and socioeconomic impact on both patients and caregivers. This knowledge is crucial for clinical development, digital health solutions, as well as social and psychological support to Alzheimer’s disease families, in the frame of a precision medicine approach to Alzheimer’s disease.This book brings together up-to-date findings from a variety of experts, covering basic neuroscience, epidemiology, diagnosis, treatment, clinical trials development, socioeconomic factors, and psychosocial support. Alzheimer’s disease, the most common form of dementia, remains an unmet medical need for the planet. Wide interpersonal variability in disease onset, presentation, and biomarker profile make Alzheimer’s a clinical challenge to neuroscientists, clinicians, and drug developers alike, resulting in huge management costs for health systems and society. Not only do women represent the majority of Alzheimer’s disease patients, but they also represent two-thirds of caregivers. Understanding sex and gender differences in Alzheimer’s disease will lead to novel insights into disease mechanisms, and will be crucial for personalized disease management strategies and solutions, involving both the patient and their family. Endorsements/Reviews: "There is a clear sex and gender gap in outcomes for brain health disorders like Alzheimer’s disease, with strikingly negative outcomes for women. This understanding calls for a more systematic way of approaching this issue of inequality. This book effectively highlights and frames inequalities in all areas across the translational spectrum from bench-to-bedside and from boardroom-to-policy and economics. Closing the Brain Health Gap will help economies create recovery and prepare our systems for future global shocks." Harris A. Eyre MBBS, PhD, co-lead, Neuroscience-inspired Policy Initiative, OECD and PRODEO Institute. Instructor in Brain Health Diplomacy, Global Brain Health Institute, UCSF and TCD. "Sex and Gender Differences in Alzheimer's disease is the most important title to emerge on Alzheimer's disease in recent years.This comprehensive, multidisciplinary book is a must read for anyone with a serious interest in dementia prevention, diagnosis, treatment, care, cure and research. Precision medicine is the future of healthcare and this book represents an incredible and necessary resource to guide practice, policy and research in light of the fact that Alzheimer's disease disproportionately affects women. The combination of contributions from the most eminent experts and the most up-to-date research makes this an invaluable resource for clinicians, care providers, academics, researchers and policy makers. Given the complex nature of dementia and the multiple factors that influence risk and disease trajectory the scope of the book is both impressive and important covering sex differences in neurobiological processes, sex and gender differences in clinical aspects and gender differences linked to socioeconomic factors relevant to Alzheimer's disease. If you work in Alzheimer's disease, or indeed other dementias, then Sex and Gender Differences in Alzheimer's disease is a must have for your bookshelf." -- Sabina Brennan, PhD., C.Psychol.,PsSI., National representative for Ireland on Alzheimer Disease International's Medical and Scientific Advisory Panel
Download or read book Epigenetics of Aging written by Trygve O. Tollefsbol and published by Springer Science & Business Media. This book was released on 2009-11-11 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.
