Book Description
Helicases are the proteins that bind to double- or single-stranded DNA and/or RNA chains to unwind higher order structures, usually consuming energy from the hydrolysis of ATP molecules. The biological roles of helicases are associated with a variety of DNA and/or RNA metabolisms, including DNA-replication, -repair, -recombination, RNA processing, and transcription. Dysfunctions of helicases cause various diseases, such as xeroderma pigmentosum (XP), premature aging syndrome, cancer and immunodeficiency, in humans. Moreover, recent genetic analyses revealed that mutations in helicase-encoding genes are frequently found in patients of specific diseases. Some helicases regulate cellular senescence by controlling integrity of genomes, and others play a role in neuromuscular functions presumably by modulating processing of mRNAs. However, the molecular mechanisms of how helicases are regulated in order to maintain our health are not yet fully understood. In this research topic, we will focus on the expression and functions of helicases and their encoding genes, reviewing recent research progresses that provide new insights into development of clinical and pharmaceutical treatments targeting helicases.

Book Description
Genome Stability: From Virus to Human Application, Second Edition, a volume in the Translational Epigenetics series, explores how various species maintain genome stability and genome diversification in response to environmental factors. Here, across thirty-eight chapters, leading researchers provide a deep analysis of genome stability in DNA/RNA viruses, prokaryotes, single cell eukaryotes, lower multicellular eukaryotes, and mammals, examining how epigenetic factors contribute to genome stability and how these species pass memories of encounters to progeny. Topics also include major DNA repair mechanisms, the role of chromatin in genome stability, human diseases associated with genome instability, and genome stability in response to aging. This second edition has been fully revised to address evolving research trends, including CRISPRs/Cas9 genome editing; conventional versus transgenic genome instability; breeding and genetic diseases associated with abnormal DNA repair; RNA and extrachromosomal DNA; cloning, stem cells, and embryo development; programmed genome instability; and conserved and divergent features of repair. This volume is an essential resource for geneticists, epigeneticists, and molecular biologists who are looking to gain a deeper understanding of this rapidly expanding field, and can also be of great use to advanced students who are looking to gain additional expertise in genome stability. - A deep analysis of genome stability research from various kingdoms, including epigenetics and transgenerational effects - Provides comprehensive coverage of mechanisms utilized by different organisms to maintain genomic stability - Contains applications of genome instability research and outcomes for human disease - Features all-new chapters on evolving areas of genome stability research, including CRISPRs/Cas9 genome editing, RNA and extrachromosomal DNA, programmed genome instability, and conserved and divergent features of repair

Book Description
This book provides a detailed evidence-based overview of the latest developments in how the structure of the human genome is relevant to the health professional. It features comprehensive reviews of genome science including human chromosomal and mitochondrial DNA structure, protein-coding and noncoding genes, and the diverse classes of repeat elements of the human genome. These concepts are then built upon to provide context as to how they functionally relate to differences in phenotypic traits that can be observed in human populations. Guidance is also provided on how this information can be applied by the medical practitioner in day-to-day clinical practice. Human Genome Structure, Function and Clinical Considerations collates the latest developments in genome science and current methods for genome analysis that are relevant for the clinician, researcher and scientist who utilises precision medicine techniques and is an essential resource for any such practitioner.

Book Description
Helicases are ubiquitous enzymes found throughout evolution. Research in the helicase field has been going on for a long time now but in recent past with the completion of so many genomes, these enzymes have been discovered in a number of organisms. But the available literature is scattered. The huge number of identified DNA and RNA helicases, along with the structural and functional differences among them, make difficult for the interested scholar to grasp a comprehensive view of the field. Helicases from all Domains of Life is the first book to compile information about helicases from many different organisms in one place. Knowledge of the functions and features of helicases across the different kingdoms of life are a valuable source of novel ideas and information The book begins with a chapter on the evolutionary history of helicases followed by three "overview" chapters: one for bacteria/archaea (which are not mentioned), one for plants/algae and one for human helicases The overview chapters are followed by specific chapters on selected helicases of great importance from a biological/applicative point of view

Book Description
In recent years, a number of groundbreaking structural and mechanistic studies deepened our understanding of helicase mechanisms and established new approaches for their analyses. Many fundamental mechanistic questions ranging from the mechanism of force generation, mechanochemical coupling to distinct mechanisms by which the same enzyme translocates on DNA removing obstacles, unwinds DNA and/or remodels nucleoprotein complexes, however, remain to be answered. It is even less understood how the helicase motors are incorporated into a wide range of genome maintenance and repair machines. The field has reached a stage when the studies of molecular mechanisms and basic biology of helicases can and shall be integrated with the studies of development, cancer and longevity. The objective of this book is to provide the first systematic overview of structure, function and regulation of DNA helicases and related molecular motors. By integrating the knowledge obtained through the diverse technical approaches ranging from single-molecule biophysics to cellular and molecular biological studies the editors aim to provide a unified view on how helicases function in the cell, are regulated in response to different cellular stresses and are integrated into large macromolecular assemblies to form a complex and adaptive living system.
