This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Long noncoding RNAs (lncRNAs) regulate chromatin remodeling through their interactions with epigenetic enzymes during development and disease. The inhibition of the natural antisense transcript of Brain-derived neurotrophic factor (BDNF-AS), results in BDNF promoter de-repression and transcriptional upregulation, both in vitro and in vivo. Recently, we showed that BDNF-AS interacts with the histone methyltransferase enhancer of zeste homolog 2 (EZH2) to suppress BDNF mRNA and protein expression. BDNF is an important neurotrophin that is required for neural development and maintenance of the nervous system. Dysregulation of BDNF occurs in a number of neurological disorders, including: Alzheimer's Disease, Parkinson's Disease, Rett syndrome, and amyotrophic lateral sclerosis. Previous attempts to upregulate BDNF by administering the recombinant form in various parts of the central nervous system have failed, mostly due to the challenge of delivering BDNF to the correct cells and neural networks. Our approach to upregulating BDNF by modulating its interaction with an epigenetic enzyme is a highly specific target with potential therapeutic value. To achieve this, we developed a novel pharmacological assay to characterize the interaction between long noncoding RNAs and their epigenetic targets using Amplified Luminescent Proximity Homogeneous Assay (AlphaScreen) technology. With this assay, we are able to quantify lncRNA-protein interactions rapidly for the purpose of high throughput screening, enabling drug discovery efforts for this novel class of drug targets. In this work, we present our assay development and screening findings, including the identification of potential small molecule modulators of lncRNA-protein interactions. Furthermore, we describe the application of this lncRNA-protein interaction assay to detect RNA requirements for EZH2 recruitment, a much debated and important question that lingers in the field. From our work, it is evident that BDNF-AS has several regions of RNA that are required for EZH2 recruitment, potentially due to the importance of this transcript in regulating BDNF. This work describes exploratory drug discovery for a novel class of drug targets as well as applications to understand the basic biochemistry governing lncRNA-protein interactions.

Download or read book Regulatory RNAs in the Nervous System 2nd Edition written by Tommaso Pizzorusso and published by Frontiers Media SA. This book was released on 2018-11-13 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until about a decade ago, the non-coding part of the genome was considered without function. RNA sequencing studies have shown, however, that a considerable part of the non-coding genome is transcribed and that these non-coding RNAs (nc-RNAs) can regulate gene expression. Almost on weekly basis, new findings reveal the regulatory role of nc-RNAs exert in many biological processes. Overall, these studies are making increasingly clear that, both in model organisms and in humans, complexity is not a function of the number of protein-coding genes, but results from the possibility of using combinations of genetic programs and controlling their spatial and temporal regulation during development, senescence and in disease by regulatory RNAs. This has generated a novel picture of gene regulatory networks where regulatory nc-RNAs represent novel layers of regulation. Particularly well-characterized is the role of microRNAs (miRNAs), small nc-RNAs, that bind to mRNAs and regulate gene expression after transcritpion. This message is particularly clear in the nervous system, where miRNAs have been involved in regulating cellular pathways controlling fundamental functions during development, synaptic plasticity and in neurodegenerative disease. It has also been shown that neuronal miRNAs are tightly regulated by electrical activity at the level of transcription, biogenesis, stability and specifically targeted to dendrites and synapses. Deregulation of expression of miRNAs is proposed not only as potential disease biomarker, but it has been implicated directly in the pathogenesis of complex neurodegenerative disease. This so-called RNA revolution also lead to the exploitation of RNA interference and the development of related tools as potential treatment of a vast array of CNS disease that could benefit from regulation of disease-associated genes. In spite of these advancements, the relatively young age of this field together with the inherent high molecular complexity of RNA regulation of biological processes have somewhat hindered its communication to the whole of the neuroscience community. This Research Topic aims at improving this aspect by putting around the same virtual table scientists covering aspects ranging from basic molecular mechanisms of regulatory RNAs in the nervous system to the analysis of the role of specific regulatory RNAs in neurobiological processes of development, plasticity and aging. Furthermore, we included papers analyzing the role of regulatory RNAs in disease models from neuromuscular to higher cognitive functions, and more technically oriented papers dealing with new methodologies to study regulatory RNA biology and its translational potential.

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.

Download or read book The Chemical Biology of Long Noncoding RNAs written by Stefan Jurga and published by Springer Nature. This book was released on 2020-10-01 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive and detailed overview of various aspects of long non-coding RNAs. It discusses their emerging significance in molecular medicine, ranging from human cancers to cardiovascular and metabolic diseases. Transcriptomic studies have demonstrated that the majority of genomes found in complex organisms are expressed in highly dynamic and cell-specific patterns, producing huge numbers of intergenic, antisense and intronic long non-protein-coding RNAs (lncRNAs). Thousands of lncRNAs have been identified, and unlike mRNA, they have no protein-coding capacity. A large repertoire of ncRNAs, actively transcribed from the mammalian genome, control diverse cellular processes, both in terms of development and diseases, through a variety of gene regulatory mechanisms. IncRNAs have emerged as a new paradigm in epigenetic regulation of the genome. Given its scope, the book will be of particular interest to molecular, chemical, cell and developmental biologists, as well as specialists in translational medicine involved in disease-oriented research. It also offers a valuable resource for in silico experts seeking a deeper understanding of lncRNA expression and function through computational analysis of the NGS data.
