Book Description
DNA topoisomerases represent an essential family of DNA processing enzymes and a large number of topoisomerase inhibitors are used clinically for the treatment of various human cancers. Novels drugs are in clinical development both against type I and type II topoisomerases. The book will include basic biochemical and structural reviews for the cancer-relevant topoisomerases. It will describe how topoisomerase dysfunctions can damage the genome and increase the risk of cancers, and the involvement of topoisomerases in programmed cell death. The book will also present the various topoisomerase inhibitors in clinical use and development and their molecular and cellular mechanisms of action.

Book Description
DNA Topoisomerase Protocols, I: DNA Topology and Enzymes brings together an unprecedented collection of cutting-edge experimental protocols for investigating DNA structure, topology, and DNA topoisomerase function. Described by expert experimentalists who have perfected the techniques, these unfailingly reproducible methods utilize new approaches to study changes in DNA topology (linking number, knotting, catenation, and relaxation) and DNA structure (bending), as well as to assess chromosome structure through FLP-mediated recombination and to analyze bacterial nucleoid structure. State-of-the-art protocols also detail the expression and purification of bacterial, viral, and eukaryotic DNA topoisomerases from a variety of sources, including baculovirus, and bacterial, yeast and mammalian expression systems. A companion volume, DNA Topoisomerase Protocols, v. 2: Enzymology and Drugs, provides detailed protocols to study the catalytic activities of DNA topoisomerases, as well as their specific interactions with topoisomerase-targeted antitumor and antibacterial drugs. DNA Topoisomerase Protocols, I: DNA Topology and Enzymes will be of immense value to the many basic scientists and clinicians who want better to understand and to exploit proficiently the wealth of recent discoveries about chromatin structure and its relation to gene expression, about DNA topoisomerases as the targets of antitumor and antibacterial agents, and about DNA repair.

Untangling the Double Helix

Untangling the Double Helix PDF Author: James C. Wang
Publisher:
ISBN:
Category : DNA topoisomerases
Languages : en
Pages : 252

Book Description
The problem of unraveling two intertwined strands during the duplication of DNA was recognized shortly after the proposal of the DNA double helix structure in 1953. A group of enzymes called DNA topoisomerases solve this problem by breaking and rejoining DNA molecules in a controlled manner, thereby allowing strands to be passed through each other and thus untangled—not just during DNA replication, but also during many other basic cellular processes. Because of their intimate involvement in the workings of the cell, topoisomerases are also the logical targets of many antibiotics (including Cipro) and anticancer agents. This book, written by James Wang, the discoverer of the first topoisomerase and a leader in the field since, presents ten chapters covering the historical backdrop of the DNA entanglement problem and the discovery of the DNA topoisomerases, how DNA topoisomerases perform their magic in DNA replication, transcription, genetic recombination and chromosome condensation, and how they are targets of therapeutic agents. The book should appeal to readers from undergraduates upwards with interests in the biological and clinical aspects of topoisomerase function, or in the mathematics and physics of topology.

DNA Topoisomerases in Cancer Therapy

DNA Topoisomerases in Cancer Therapy PDF Author: Toshiwo Andoh
Publisher: Springer Science & Business Media
ISBN: 1461501415
Category : Science
Languages : en
Pages : 208

Book Description
In the mid 80's type I and II enzymes were found to be the intracellular targets of a number of efficacious anticancer drugs such as doxorubicin, mitoxantrone, etoposide and camptothecin as a result of a continued efforts of many investigators, especially Leroy Liu and his collaborators at Johns Hopkins University. Readers will find a series of chapters written by researchers actively engaged in the expanding field of topoisomerase and their inhibitors. The series of chapters cover review articles on pharmacology and the molecular mechanism of topoisomerase I- and II-targeting anticancer drugs in mammals and in the yeast Saccharomyces cerevisiae, which has proved to be a superb model organism for studies of anticancer drugs. This volume compiles up-to-date information on the topoisomerase-targeting compounds in clinical and preclinical development as a useful and important reference book for students and researchers in the field of pharmacology, toxicology, oncology and molecular biology.

Languages : en
Pages : 331

Book Description
Beginning with the Escherichia coli ? protein, or bacterial DNA topoisomerase I, an ever-increasing number of enzymes have been identified that catalyze changes in the linkage of DNA strands. DNA topoisomerases are ubiquitous in nature and have been shown to play critical roles in most p- cesses involving DNA, including DNA replication, transcription, and rec- bination. These enzymes further constitute the cellular targets of a number of clinically important antibacterial and anticancer agents. Thus, further studies of DNA topology and DNA topoisomerases are critical to advance our und- standing of the basic biological processes required for cell cycle progression, cell division, genomic stability, and development. In addition, these studies will continue to provide critical insights into the cytotoxic action of drugs that target DNA topoisomerases. Such mechanistic studies have already played an important role in the development and clinical application of antimicrobial and chemotherapeutic agents. The two volumes of DNA Topoisomerase Protocols are designed to help new and established researchers investigate all aspects of DNA topology and the function of these enzymes. The chapters are written by prominent investigators in the field and provide detailed background information and st- by-step experimental protocols. The topics covered in Part I: DNA Topology and Enzymes, range from detailed methods to analyze various aspects of DNA structure, from linking number, knotting/unknotting, site-specific recombi- tion, and decatenation to the overexpression and purification of bacterial and eukaryotic DNA topoisomerases from a variety of cell systems and tissues.

Category : Medical
Languages : en
Pages : 400

Book Description
Molecular Biology of DNA Topoisomerases and Its Application to Chemotherapy is based on conference proceedings from the International Symposium on DNA Topoisomerases in Chemotherapy, held in Nagoya, Japan, in November 1991. The book opens with a discussion of the structural and functional properties of various types of DNA topoisomerases identified in prokaryotes and eukaryotes, in addition to their roles as cellular targets of anticancer and antimicrobial agents. Other topics addressed include the genetics and biology of DNA topoisomerases, inhibitors of microbial DNA topoisomerases and drug resistance, inhibitors of mammalian DNA topoisomerases and drug resistance, and preclinical and clinical studies of DNA topoisomerase inhibitors. Molecular Biology of DNA Topoisomerases and Its Application to Chemotherapy will broaden the understanding of biology and genetics of DNA topoisomerases and contribute to the development of antimicrobial and anticancer agents-inhibitors of topoisomerases. It will be invaluable for oncologists, molecular biologists, cellular biologists, geneticists, biochemists, and pharmaceutical researchers.

DNA Topoisomerases in Cancer

DNA Topoisomerases in Cancer PDF Author: Milan Potmesil
Publisher: Oxford University Press, USA
ISBN:
Category : Medical
Languages : en
Pages : 364

Book Description
DNA Topoisomerases are a unique class of enzymes that are responsible for the control and modification of DNA topology (tertiary structure); one example of their function is the transformation of chromosomes from a supercoiled condensed state to uncoiled strands and vice versa. They are of interest both for their intrinsic role in cell biology (i.e. control of cell division) and also because some anticancer drugs, such as camptothecin, act by inhibiting their action.
