Book Description
M. B. KASTAN Cancer is a disease resulting from alterations of cellular genes which cause phe notypic changes in somatic cells. Usually, when we think about genetic diseases, we think about inheriting one or two abnormal genes from our parents and these gene abnormalities confer the disease phenotype. In contrast, in the majority of cancers, no such inherited gene abnormalities can be identified (which does not mean that they do not exist) and there is no obvious family history suggesting an inherited disease. The vast majority of genes which are altered in the cancer cells are not transmitted through the germ line, but rather become abnormal in somatic cells sometime during the lifetime of the individual. Thus, the critical question which arises is "how do these genetic changes occur in somatic cells?". Epidemiologic data suggest that exposure to environmental carcinogens con tributes to the genesis of at least 80% of all human cancers (DOLL and PETO 1981). Thus, it is natural to suspect that the genetic changes in somatic cells which con tribute to the transformed phenotype arise from DNA damage caused by such exposures. Therefore, understanding how cells respond to DNA-damaging agents is likely to be an important component of our understanding of the genesis of human tumors.

Book Description
Research over the past decades has firmly established the genetic basis of cancer. In particular, studies on animal tumour viruses and chromosome rearrangements in human tumours have concurred to identify so-called ‘proto-oncogenes’ and ‘tumour suppressor genes’, whose deregulation promotes carcinogenesis. These important findings not only explain the occurrence of certain hereditary tumours, but they also set the stage for the development of anti-cancer drugs that specifically target activated oncogenes. However, in spite of tremendous progress towards the elucidation of key signalling pathways involved in carcinogenesis, most cancers continue to elude currently available therapies. This stands as a reminder that “cancer” is an extraordinarily complex disease: although some cancers of the haematopoietic system show only a limited number of characteristic chromosomal aberrations, most solid tumours display a myriad of genetic changes and considerable genetic heterogeneity. This is thought to reflect a trait commonly referred to as ‘genome instability’, so that no two cancers are ever likely to display the exact same genetic alterations. Numerical and structural chromosome aberrations were recognised as a hallmark of human tumours for more than a century. Yet, the causes and consequences of these aberrations still remain to be fully understood. In particular, the question of how genome instability impacts on the development of human cancers continues to evoke intense debate.

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 volume began with an invitation from the publishers to edit a volume of EXS on Cancer. This invitation undoubtedly derived from my articles in Cellular and Molecular Life Sciences in 2002 and 2003 on the relationships between the morphology, aetiology and pathogenesis of tumours, especially in relation to genetic instability. After many years of teaching the theories of c- cer in undergraduate medical school courses, it seemed to me that the variably chaotic histopathologic features of tumours parallel in some way, the variably unstable genomes of tumour cells, which were being discovered in the 1990s. Thus the title of the volume has come to include morphology, carcinogenesis and genetic instability. The invitation came while I was working with Herrn Dr. med. Hubertus Jersmann (MD Düsseldorf, PhD, now Senior Lecturer in Medicine of the University of Adelaide) and Professor Brian Coghlan (Emeritus Professor of German, the University of Adelaide), on the work of the nineteenth century cancer pathologists, especially David Paul von Hansemann (1858–1920). With the delivery of the manuscripts from the authors of the chapters, it became obvious that a background chapter for the volume could include some of the material which we had “uncovered” together. Because of this, chapter 1 is authored by the three of us, and the “new” material figures prominently.

Book Description
Many cancer biologists now believe that genomic instability not only initiates carcinogenesis, but also allows the tumour cell to become metastatic and evade drug toxicity. The loss of stability of the genome is becoming accepted as one of the most important aspects of carcinogenesis. One of the hallmarks of the cancer cell is the inherent instability of its genome. This book presents important research in this exciting field.

Book Description
Since the establishment of the DNA structure researchers have been highly interested in the molecular basis of the inheritance of genes and of genetic disorders. Scientific investigations of the last two decades have shown that, in addition to oncogenic viruses and signalling pathways alterations, genomic instability is important in the development of cancer. This view is supported by the findings that aneuploidy, which results from chromosome instability, is one of the hallmarks of cancer cells. Chromosomal instability also underpins our fundamental principles of understanding tumourigenesis: It thought that cancer arises from the sequential acquisition of genetic alterations in specific genes. In this hypothesis, these rare genetic events represent rate-limiting ‘bottlenecks’ in the clonal evolution of a cancer, and pre-cancerous cells can evolve into neoplastic cells through the acquisition of somatic mutations. This book is written by international leading scientists in the field of genome stability. Chapters are devoted to genome stability and anti-cancer drug targets, histone modifications, chromatin factors, DNA repair, apoptosis and many other key areas of research. The chapters give insights into the newest development of the genome stability and human diseases and bring the current understanding of the mechanisms leading to chromosome instability and their potential for clinical impact to the reader.

Book Description
This issue of Recent Results in Cancer Research presents a comprehensive review of current understanding of chromosomal instability in cancer and of strategies to use this information for better treatment of patients with cancer. Cancer is a disease of the chromosomes, and chromosomal instability in cancer disrupts gene function by either inactivating tumor suppressor genes or activating growth-promoting oncogenes. The chromosomal basis for these aberrations is either translocations, which change the integrity of genes, or abnormal numbers of chromosomes, a condition referred to as aneuploidy, which results in abnormal gene expression levels. Such structural or numerical chromosomal aberrations are specific for distinct tumor entities. The degree of chromosomal instability and the degree of intratumor heterogeneity have profound consequences for disease outcome and for therapeutic stratification.
