Book Description
Maintenance of the information embedded in the genomic DNA sequence is essential for life. DNA polymerases play pivotal roles in the complex processes that maintain genetic integrity. Besides their tasks in vivo, DNA polymerases are the workhorses in numerous biotechnology applications such as the polymerase chain reaction (PCR), cDNA cloning, genome sequencing, nucleic acids-based diagnostics and in techniques to analyze ancient and otherwise damaged DNA. Moreover, some diseases are related to DNA polymerase defects, and chemotherapy through inhibition of DNA polymerases is used to fight HIV, Herpes and Hepatitis B and C infections. We have recently witnessed the discovery of an abundance of novel DNA polymerases in viruses, bacteria, archaea and eukaryotes with specialized properties whose physiological functions are only beginning to be understood. This book summarizes the current knowledge of these fascinating enzymes. It is intended for a wide audience from basic scientists, to diagnostic laboratories and to clinicians who seek a better understanding of these fascinating enzymes.

Book Description
The DNA of all organisms is constantly being damaged by endogenous and exogenous sources. Oxygen metabolism generates reactive species that can damage DNA, proteins and other organic compounds in living cells. Exogenous sources include ionizing and ultraviolet radiations, carcinogenic compounds and environmental toxins among others. The discovery of multiple DNA lesions and DNA repair mechanisms showed the involvement of DNA damage and DNA repair in the pathogenesis of many human diseases, most notably cancer. These books provide a comprehensive overview of the interdisciplinary area of DNA damage and DNA repair, and their relevance to disease pathology. Edited by recognised leaders in the field, this two-volume set is an appealing resource to a variety of readers including chemists, chemical biologists, geneticists, cancer researchers and drug discovery scientists.

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 will serve as the preeminent text book on the topic of 'base excision repair', a key DNA repair pathway that protects cells from most spontaneous forms of DNA damage, including oxidative lesions that arise both in the nuclear and mitochondrial genomes. The book, which includes contributions from many of the world leaders in the field, provides a detailed description of the molecular mechanisms of base excision repair, as well as its emerging relationship to epigenetic regulation, the aging process and human disease, such as cancer susceptibility, immunological defects and neurological disorders. The book will also cover the state-of-the-art technologies being developed to assess base excision repair capacity among individuals in the population, in addition to the strategies being employed to target base excision repair as part of therapeutic paradigms to eradicate disease, namely cancer.This book represents one of the most extensive efforts to date to cover the topic of 'base excision repair'. It includes chapters by many of the most established investigators in the field, from all over the world.

Book Description
DNA is under constant challenge from environmental and endogenous metabolic assaults. Several layers of defence and repair systems allow cells to maintain stable genomes; in humans, dysfunction of these systems leads to cancer, neurodegeneration, and other pathologies. At the same time, recently it had emerged that targeted and regulated DNA damage and repair is a mechanism underlying several important cellular processes such as epigenetic demethylation and immunoglobulin gene diversification. The present collection of papers is aimed to cover new developments in the area of protective and regulatory mechanisms associated with DNA damage. The mechanisms ruling the recognition of damaged nucleotides against the vast background of normal ones are reviewed. The role of extended non-catalytic domains that are often found in eukaryotic DNA repair proteins in contrast to their downsized, catalytic-only bacterial counterparts is discussed. Among the proposed subjects are the regulatory functions of bulky covalent modifications such as poly(ADP)ribosylation and ubiquitylation in DNA damage response, especially in the context of chromatin remodelling. As opposed to DNA repair, damage tolerance allows cells to replicate with lesions in the genome; the enzymes responsible are also covered. Finally, we present examples of modern multilevel understanding of the cell function and malfunction in the wake of genotoxic assaults such as oxidative stress, abiotic environmental stress, and DNA-damaging plant toxins.
