Download or read book Integrative Multi Omics for Diagnosis Treatments and Drug Discovery of Aging Related Neuronal Diseases written by Min Tang and published by Frontiers Media SA. This book was released on 2022-11-23 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the cost of high-throughput sequencing goes down, huge volumes of biological and medical data have been produced from various sequencing platforms at multiple molecular levels including genome, transcriptome, proteome, epigenome, metabolome, and so on. For a long time, data analysis on single molecular levels has paved the way to answer many important research questions. However, many Aging-Related Neuronal Diseases (ARNDs) and Central Nervous System (CNS) aging involve interactions of molecules from multiple molecular levels, in which conclusions based on single molecular levels are usually incomplete and sometimes misleading. In these scenarios, multi-omics data analysis has unprecedentedly helped capture much more useful information for the diagnosis, treatment, prognosis, and drug discovery of ARNDs. The first step towards a multi-omics analysis is to establish reliable and robust multi-omics datasets. In the past years, a few important ARNDs-associated multi-omics databases like Allen Brain have been constructed, which raised immediate needs like data curation, normalization, interpretation, and visualization for integrative multi-omics explorations. Though there have been several well-established multi-omics databases for ARNDs like Alzheimer’s disease, similar databases for other ARNDs are still in urgent need. After the databases establish, many computational tools and experiential strategies should be developed specifically for them. First, the multi-omics data are usually extremely noisy, complex, heterogeneous and in high dimension, which presents the need for appropriate denoising and dimension reduction methods. Second, since the multi-omics and non-omics data like pathological and clinical data are usually in different data spaces, a useful algorithm to mapping them into the same data space and integrate them is nontrivial. In the multi-omics era, there are numerous data-centric tools for the integration of multi-omics datasets, which could be generally divided into three categories: unsupervised, supervised, and semi-supervised methods. Commonly used algorithms include but not limited to Bayesian-based methods, Network-based methods, multi-step analysis methods, and multiple kernel learning methods. Third, methods are needed in studying and verifying the association between two or more levels of multi-omics data and non-omics data. For example, expression quantitative trait loci (eQTL) analysis is widely used to infer the association between a single nucleotide polymorphism (SNP) and the expression of a gene. Recently, the association between omics data and more complex data like pathological and clinical imaging data has been a hot research topic. The outcomes may reveal the underlying molecular mechanism and promote de novo drug design as well as drug repurposing for ARNDs. Here, we welcome investigators to share their Original Research, Review, Mini Review, Hypothesis and Theory, Perspective, Conceptual Analysis, Data Report, Brief Research Report, Code related to multi-omics studies of ARNDs, which can be applied for better diagnosis, treatment, prognosis and drug discovery of human diseases in the future era of precision medicine. Potential contents include but are not limited to the following: ▪ Methods for integrating, interpreting, or visualizing two or more omics data. ▪ Methods for identifying interactions between different data modalities. ▪ Methods for disease subtyping, biomarker prediction. ▪ Machine learning or deep learning methods on dimensional reduction and feature selection for big noisy data. ▪ Methods for studying the association among different omics data or between omics and non-omics data like clinical, pathological, and imaging data. ▪ Review of multi-omics resource about ARNDs and/or CNS aging. ▪ Experimental validation of biomarkers identified from multi-omics data analysis. ▪ Disease diagnosis and prognosis prediction from imaging and non-imaging data analysis, or both. ▪ Clinical applications or validations of findings from multi-omics data analysis.

Download or read book Development and Application of Multi omics Integration Tools to Understand Metabolic Contributions to Alzheimer s Disease written by Jessica Ding and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological functioning of an organ system such as healthy brain functioning is enabled by orchestrated information flow between molecular entities within cells, between cells, and across tissues and its understanding requires a systems approach. In complex disease such as Alzheimer's disease, there are numerous subtle, moderate, and strong perturbations across biological networks which result in disease onset and progression. High-throughput multi-omics profiling of genetic variants, the epigenome, transcriptome, proteome, metabolome, and microbiome is a first step in probing the complexity of biological systems and disease etiologies. There remains the problems of multi-omics integration, modeling and interpretation, and accessibility of computational analyses. To address these issues, in the methods development section of my dissertation research, I developed the complete overhaul of the web server for Mergeomics, a method for pathway- and network-level understanding of complex disease using multi-omics integration, which significantly improved the usability and functionality of the tool. To facilitate omics-driven drug discovery, I implemented the PharmOmics web server and the direct pipeline from Mergeomics, allowing users to gain immediate therapeutic insight from disease-associated pathways, key drivers, and key driver subnetworks. The second focus of my dissertation was the application of systems biology analytical tools to understand metabolic contributions to Alzheimer's disease. I determined hippocampal and hypothalamic cell type specific alterations in response to amyloid-beta accumulation in the 5XFAD mouse model and investigated the effect of metabolically challenging 5XFAD mice with fructose overconsumption and supplementation with docosahexaenoic acid and nicotinamide riboside. I identified cell type- and tissue-resolved pathway and network mechanisms of disease exacerbation by metabolic challenge and disease alleviation by docosahexaenoic acid and nicotinamide. My efforts in developing the web server implementations of Mergeomics and PharmOmics have promoted greater accessibility of deriving mechanistic insight from big biological data for the broader scientific community, and use of these tools have allowed unbiased examination into the connection between metabolic syndrome and Alzheimer's disease and uncovered potential therapeutic targets and strategies via dietary modulation.

Available in PDF, EPUB and Kindle. Book excerpt: Technologies collectively called omics enable simultaneous measurement of an enormous number of biomolecules; for example, genomics investigates thousands of DNA sequences, and proteomics examines large numbers of proteins. Scientists are using these technologies to develop innovative tests to detect disease and to predict a patient's likelihood of responding to specific drugs. Following a recent case involving premature use of omics-based tests in cancer clinical trials at Duke University, the NCI requested that the IOM establish a committee to recommend ways to strengthen omics-based test development and evaluation. This report identifies best practices to enhance development, evaluation, and translation of omics-based tests while simultaneously reinforcing steps to ensure that these tests are appropriately assessed for scientific validity before they are used to guide patient treatment in clinical trials.

Download or read book Biologically Interpretable Machine Learning Methods to Understand Gene Regulation for Disease Phenotypes written by Ting Jin and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene expression and regulation is a key molecular mechanism driving the development of human diseases, particularly at the cell type level, but it remains elusive. For example in many brain diseases, such as Alzheimer's disease (AD), understanding how cell-type gene expression and regulation change across multiple stages of AD progression is still challenging. Moreover, interindividual variability of gene expression and regulation is a known characteristic of the human brain and brain diseases. However, it is still unclear how interindividual variability affects personalized gene regulation in brain diseases including AD, thereby contributing to their heterogeneity. Recent technological advances have enabled the detection of gene regulation activities through multi-omics (i.e., genomics, transcriptomics, epigenomics, proteomics). In particular, emerging single-cell sequencing technologies (e.g., scRNA-seq, scATAC-seq) allow us to study functional genomics and gene regulation at the cell-type level. Moreover, these multi-omics data of populations (e.g., human individuals) provide a unique opportunity to study the underlying regulatory mechanisms occurring in brain disease progression and clinical phenotypes. For instance, PsychAD is a large project generating single-cell multi-omics data including many neuronal and glial cell types, aiming to understand the molecular mechanisms of neuropsychiatric symptoms of multiple brain diseases (e.g., AD, SCZ, ASD, Bipolar) from over 1,000 individuals. However, analyzing and integrating large-scale multi-omics data at the population level, as well as understanding the mechanisms of gene regulation, also remains a challenge. Machine learning is a powerful and emerging tool to decode the unique complexities and heterogeneity of human diseases. For instance, Beebe-Wang, Nicosia, et al. developed MD-AD, a multi-task neural network model to predict various disease phenotypes in AD patients using RNA-seq. Additionally, with advancements in graph neural networks, which possess enhanced capabilities to represent sophisticated gene network structures like gene regulation networks that control gene expression. Efforts have also been made to capture the gene regulation heterogeneity of brain diseases. For instance, Kim SY has applied graph convolutional networks to offer personalized diagnostic insights through population graphs that correspond with disease progression. However, many existing machine learning methods are often limited to constructing accurate models for disease phenotype prediction and frequently lack biological interpretability or personalized insights, especially in gene regulation. Therefore, to address these challenges, my Ph.D. works have developed three machine-learning methods designed to decode the gene regulation mechanisms of human diseases. First, in this dissertation, I will present scGRNom, a computational pipeline that integrates multi-omic data to construct cell-type gene regulatory networks (GRNs) linking non-coding regulatory elements. Next, I will introduce i-BrainMap an interpretable knowledge-guided graph neural network model to prioritize personalized cell type disease genes, regulatory linkages, and modules. Thirdly, I introduce ECMaker, a semi-restricted Boltzmann machine (semi-RBM) method for identifying gene networks to predict diseases and clinical phenotypes. Overall, all our interpretable machine learning models improve phenotype prediction, prioritize key genes and networks associated with disease phenotypes, and are further aimed at enhancing our understanding of gene regulatory mechanisms driving disease progression and clinical phenotypes.

Download or read book Sex and Gender Differences in Alzheimer s Disease written by Maria Teresa Ferretti and published by Academic Press. 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 Stroke Genetics written by Hugh S. Markus and published by Oxford Medical Publications. This book was released on 2003 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stroke is a major cause of death and the major cause of adult neurological disability in most of the world. Despite its importance on a population basis, research into the genetics of stroke has lagged behind that of many other disorders. However, the situation is now changing. Anincreasing number of single gene disorders causing stroke are being described, and there is growing evidence that polygenic factors are important in the risk of apparently "sporadic" stroke.Stroke Genetics provides an up-to-date review of the area, suitable for clinicians treating stroke patients, and both clinical and non-clinical researchers in the field of cerebrovascular disease. The full range of monogenic stroke disorders causing cerebrovascular disease, including ischaemicstroke, intracerebral haemorrhage, aneurysms and arteriovenous malformations, are covered. For each, clinical features, diagnosis, and genetics are described. Increasing evidence suggest that genetic factors are also important for the much more common multifactorial stroke; this evidence isreviewed along with the results of genetic studies in this area. Optimal and novel strategies for investigating multifactorial stroke, including the use of intermediate phenotypes such as intima-media thickness and MRI detected small vessel disease are reviewed. The book concludes by describing apractical approach to investigating patients with stroke for underlying genetic disorders. Also included is a list of useful websites.
