Book Description
The ?eld of cellular responses to DNA damage has attained widespread recognition and interest in recent years commensurate with its fundamental role in the ma- tenance of genomic stability. These responses, which are essential to preventing cellular death or malignant transformation, are organized into a sophisticated s- tem designated the “DNA damage response”. This system operates in all living organisms to maintain genomic stability in the face of constant attacks on the DNA from a variety of endogenous by-products of normal metabolism, as well as exogenous agents such as radiation and toxic chemicals in the environment. The response repairs DNA damage via an intricate cellular signal transduction network that coordinates with various processes such as regulation of DNA replication, tr- scriptional responses, and temporary cell cycle arrest to allow the repair to take place. Defects in this system result in severe genetic disorders involving tissue degeneration, sensitivity to speci?c damaging agents, immunode?ciency, genomic instability, cancer predisposition and premature aging. The ?nding that many of the crucial players involved in DNA damage response are structurally and functionally conserved in different species spurred discoveries of new players through similar analyses in yeast and mammals. We now understand the chain of events that leads to instantaneous activation of the massive cellular responses to DNA lesions. This book summarizes several new concepts in this rapidly evolving ?eld, and the advances in our understanding of the complex network of processes that respond to DNA damage.

Book Description
Physical and chemical agents in the environment damage the DNA of humans, and pose a major threat to human health today, and to the genetic integrity of human populations. Although studies on isolated DNA in vitro, on prokaryotes, on mammalian cells in culture, and on laboratory animals have provided essential background information, it is now possible to study DNA damage and repair in human tissues directly. New techniques of high sensitivity, especially those not requiring radioactive labeling have made possible quantitation of DNA damage and repair, as well as detection of residual, unrepaired DNA lesions . In recent years, several investigators have taken up the challenge of studying damage and repair responses in humans, and we have chosen that work as the special focus of this Symposium. Major advances in under standing damage and responses in human skin, in blood cells and in human internal organs indicate three major themes. First, DNA damage levels in human tissues depend not only on the initial exposures, but also on the capapacity of that tissue for repair of the specific lesion type. Second, repair in human tissues may differ quantitatively and qualitatively from that in human cells in culture.

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.

Book Description
Living cells have evolved many ways of coping with metabolic events and environmental influences that damage DNA. These mechanisms, and the frequent progression to cancer that results when they go awry, are rev iewed in this volume by authors from over sixty of the world's leading laboratories. The topics discussed include DNA repair, mutagenesis and other damage-tolerance functions, checkpoint control, apoptosis, and adaptation. They draw from studies on human and yeast cells. Current, but with a valuable historical perspective, this volume has the depth and lasting value typical of this most prestigious series and is esse ntial reading for investigators of DNA replication, cell cycle control, and tumorigenesis.
