Available in PDF, EPUB and Kindle. Book excerpt: Heritable human genome editing - making changes to the genetic material of eggs, sperm, or any cells that lead to their development, including the cells of early embryos, and establishing a pregnancy - raises not only scientific and medical considerations but also a host of ethical, moral, and societal issues. Human embryos whose genomes have been edited should not be used to create a pregnancy until it is established that precise genomic changes can be made reliably and without introducing undesired changes - criteria that have not yet been met, says Heritable Human Genome Editing. From an international commission of the U.S. National Academy of Medicine, U.S. National Academy of Sciences, and the U.K.'s Royal Society, the report considers potential benefits, harms, and uncertainties associated with genome editing technologies and defines a translational pathway from rigorous preclinical research to initial clinical uses, should a country decide to permit such uses. The report specifies stringent preclinical and clinical requirements for establishing safety and efficacy, and for undertaking long-term monitoring of outcomes. Extensive national and international dialogue is needed before any country decides whether to permit clinical use of this technology, according to the report, which identifies essential elements of national and international scientific governance and oversight.
Download or read book Epigenetics in Plants of Agronomic Importance Fundamentals and Applications written by Raúl Alvarez-Venegas and published by Springer. This book was released on 2014-07-22 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decades, chromatin remodelling has emerged as an important regulator of gene expression and plant defense. This book provides a detailed understanding of the epigenetic mechanisms involved in plants of agronomic importance. The information presented here is significant because it is expected to provide the knowledge needed to develop in the future treatments to manipulate and selectively activate/inhibit proteins and metabolic pathways to counter pathogens, to treat important diseases and to increase crop productivity. New approaches of this kind and the development of new technologies will certainly increase our knowledge of currently known post-translational modifications and facilitate the understanding of their roles in, for example, host-pathogen interactions and crop productivity. Furthermore, we provide important insight on how the plant epigenome changes in response to developmental or environmental stimuli, how chromatin modifications are established and maintained, to which degree they are used throughout the genome, and how chromatin modifications influence each another.
Download or read book Discovering and Engineering New Epigenome Editing Tools for Better Gene Expression and Epigenetic Memory Control Across Different Contexts written by Mike Vi Van and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Although all cell types in a multicellular organism contain the same genetic information, they are functionally and morphologically different. Such diversity can only be achieved by a highly regulated spatial and temporal control of gene expression by over 2000 transcription factors and chromatin regulators. The utilization of these transcriptional effector domains in gene regulation tools, as in CRISPRi/a and genetic circuits, have been instrumental in interrogating regulatory elements and gene function and holds promise for therapeutic gene or cell therapy applications. However, there is a need for new tools that do not rely on overexpressing effector domains and are small enough to deliver and combine for use in gene regulation tools. There is also the lack of systematic understanding of how effector domains regulate transcription across genomic and cell-type contexts and how their function depends on cellular cofactors. Characterizing the context of how these effectors function will help in the development of gene regulation tools that can perform across different contexts. First (in chapter 2), I develop a strategy for gene control using small single domain antibodies, called nanobodies, that bind and recruit endogenous chromatin regulators to a gene. I show that an antiGFP nanobody can be used to simultaneously visualize GFP-tagged chromatin regulators and control gene expression, and that nanobodies against two different types of repressive chromatin regulators, HP1 and DNMT1, can silence a fluorescent reporter gene. Combining these nanobodies together or with other regulators, such as DNMT3A or KRAB, I observe enhanced silencing speed and epigenetic memory. Finally, I use the slow silencing speed and high memory of antiDNMT1 to build a signal duration timer and recorder. These results set the basis for using compact nanobodies against chromatin regulators for controlling gene expression and epigenetic memory. To better understand how the dynamics and mechanisms of chromatin-mediated gene control can vary in different cell types (chapter 3), I study the effect of two repressive histone methyltransferases, KRAB and EED, on gene expression and epigenetic memory at a fluorescent reporter gene in mouse embryonic stem cells (mESCs) and Chinese hamster ovary (CHO-K1) cells. I find that, when compared to CHO-K1 cells, KRAB had slower rates of silencing and that EED can only partially silence in mESCs. Moreover, silencing mediated by these effectors had shorter duration of epigenetic memory in mESCs, such that EED silencing was completely reversible. Overall, these results provide a preliminary look into the cell-type specific function of these regulators in stem cells and acts as a steppingstone for future experiments characterizing more transcriptional effectors across different contexts, such as cell-type, gene target, and DNA-binding domain. Lastly (in chapter 4), I used high-throughput recruitment (HT-recruit) to measure effector function for a pooled library of about 6,000 nuclear protein domains across 15 target gene, cell-type, and DNA-binding domain contexts. I discover context-dependent effectors (e.g., WW and HLH domains) and identify other context-independent effectors that can improve transcriptional perturbation tools (e.g., the tripartite activator NFZ and the ZNF705F KRAB repressor). Moreover, using CRISPR screens, we identify genetic dependencies for the context-dependent HLH repressors. Ultimately, these results reveal the context-dependence across human effectors, demonstrates how rare cell type- and target-specific effectors can be systematically characterized by combined high-throughput protein domain and genetic perturbation screens, and enables a new suite of transcriptional control tools for research and therapeutic applications. Collectively, this dissertation demonstrates my work in discovering and engineering epigenetic tools that allow for better and more potent transcriptional control across different genomic and cell-type contexts, in hopes of improving upon the existing gene regulation toolbox.

Download or read book Studies Towards Developing Inducible Epigenome Editing Tools to Understand Epigenetic Crosstalk written by Weiye Zhao and published by . This book was released on 2021 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several epigenetic mechanisms including histone posttranslational modifications (PTMs) concertedly regulate gene expression. Due to the complexity and the dynamic nature of epigenetic networks, it has been difficult using convention genetic approaches to define the causalities among different epigenetic and gene expression events as well as the crosstalk between different epigenetic regulatory mechanisms, for example the interplay between histone PTMs to control gene activities. To address these limitations, my thesis work has been focused on studies that will facilitate the development of novel temporally controlled epigenome editing technologies and the understanding of crosstalk between histone PTMs in gene regulation. The ultimate goal is to develop chemically inducible multiplex platforms for epigenome editing by integrating CRISPR/dCas9 and chemically induced proximity (CIP) methods, which will allow the precise dissection of causal relationships and interplays between different epigenetic and transcription events. To achieve independent editing of multiple epigenetic marks in a temporal controllable fashion, a novel orthogonal CIP system has been developed through engineering the auxin signaling pathway from plants. Furthermore, the crosstalk between H3K27ac and H3K4me3, two histone PTMs positively associated with active transcription, and their impacts on gene activity, have been investigated through locus-specific CRISPR/dCas9-based epigenome editing approaches, which revealed some limitations in methods for epigenetic research without high resolution temporal controls. The future goal will be to combine orthogonal CIP systems to enable simultaneous or sequential recruitment of two epigenetic editing factors to chosen genome loci in temporal specific manners to manipulate local epigenetic environment and define their interrelationship and with gene activity.
