Dna Tumor Viruses

This unique book focuses on the DNA viruses in the human population that are associated with cancers. It covers most of the viruses that are thought to contribute to human malignancy. This book represents a comprehensive review of the field of DNA tumor virology. Right now, while there are books out there that cover individual viruses that are also covered in this book, there is no single book that covers this topic comprehensively. This book is the first current, comprehensive review of its kind in the market.

Topics covered range from an overview of the contribution of DNA tumour viruses to the cancer burden worldwide, and the molecular pathogenesis of virus driven cancers to vaccine development.

Approximately 15% of human cancer incidence can be attributed to virus infection, i.e. viruses represent the second most important risk factor (after tobacco consumption) for cancer development in humans. Today, five virus types are known to be involved in causing human cancer: papillomaviruses, retroviruses, herpesviruses, hepadnaviruses, and flaviviruses. This volume provides a comprehensive review of a number of DNA tumor viruses. Leading experts in the field of tumor virology discuss up-to-date information, focusing on the transforming genes of DNA tumor viruses, the mechanisms of transformation and the in vitro methodology used for their identification and characterization. In vitro studies have revealed several common mechanisms of viral transformation. Presented in a clear and concise manner, this book will be of value to students as well as researchers in the fields of general biology, molecular biology, cell biology and microbiology.

DNA tumor viruses have long been useful experimental models of carcinogenesis and have elucidated several important mechanisms of cell transformation. Re search in recent years has shown that human tumors have a multifactorial nature and that some DNA tumor viruses may playa key role in their etiology. The aim of this book is to assess our knowledge of DNA tumor viruses by reviewing animal models, mechanisms of transformation, association with human tumors, and possi bilities of prevention and control by vaccination. Animal models of tumor virology have contributed significantly to our under standing of the epidemiology and pathogenesis of virus-induced tumors. Bovine papillomaviruses induce papillomas in the intestine of cattle. The papillomas undergo a transition to carcinomas in cows feeding on bracken fern, which pro duces a toxin with radiomimetic and immunosuppressive functions. This example of cooperation between a virus and chemical carcinogens parallels the cooperative role of human papillomaviruses (HPVs) and herpes simplex virus type 2 (HSV-2) with environmental carcinogens in the pathogenesis of cervical cancer. Likewise, hepatocarcinomas appearing in woodchucks chronically infected by woodchuck hepatitis virus (WIN) provide strong support for the relationship between hepatitis B virus (HBV) infection and human hepatocellular carcinoma. Also, the fact that WIN DNA integrates closely to cellular oncogenes suggests a possible molecular mechanism for the tumorigenesis induced by HBV.

This book focuses on the DNA viruses in the human population that are associated with cancers. It covers most of the viruses that are thought to contribute to human malignancy. The book represents a comprehensive review of the field of DNA tumor virology.

This single reference on DNA tumor viruses in animal models and humans presents the latest studies on mechanisms of virus transformation, their association with human tumors, and the possibility of prevention and control by vaccination. Chapters provide current information on the epidemiology and pathogenesis of virus-induced tumors and offer insights into future prospects of immunological intervention. Biomedical researchers, clinicians, and virologists will benefit from this key resource.

Small DNA tumor viruses are a fascinating group of double-stranded DNA viruses, made up of the polyomavirus, the adenovirus, and the papillomavirus families. These viruses continue to provide fundamental insights into mammalian cell transformation, cell cycle control, and tumor formation. The causal link between papillomaviruses and some human cancers is well known, and a role for polyomavirus in human cancer has recently been established. Adenoviruses do not cause cancer in humans, but, as well as providing excellent tools for the study of host cell processes, these viruses have been exploited as delivery vehicles in gene therapy for diseases, such as cystic fibrosis and cancer. A common feature of small DNA tumor viruses is their heavy reliance on the host for survival and replication. Understanding the virus-host relationship is critical to understanding the tumorigenic process and how these viruses subvert the host's immune system. In this timely book, leading scientists from around the world review current hot topics in this area, providing a fascinating overview of the molecular biology of these viruses and their interactions with the host. The topics covered include: HPV infections and the production of HPV virion stocks * viral oncoproteins and their functions * the replication and maintenance of viral genomes * virus-induced alterations in cellular miRNAs * viral deregulation of DNA damage responses * the initiation of viral DNA replication * induction of genomic instability by viral oncoproteins * targeting of PML proteins and PML nuclear bodies by these viruses * adenoviruses and gene therapy. The book will be essential reading for scientists and researchers working on small DNA tumor viruses and their associated diseases. It is also a recommended text for anyone involved with DNA replication, DNA damage responses and genome instability, virus-host interactions, and viral tumorigenesis or antiviral drug development.
