Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book DNA Topoisomerase Protocols written by Neil Osheroff and published by Springer Science & Business Media. This book was released on 2008-02-05 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Untangling the Double Helix written by James C. Wang and published by . This book was released on 2009 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Cytotoxic Payloads for Antibody Drug Conjugates written by David E Thurston and published by Royal Society of Chemistry. This book was released on 2019-07-11 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibody–drug conjugates (ADCs) represent one of the most promising and exciting areas of anticancer drug discovery. Five ADCs are now approved in the US and EU [i.e., ado-trastuzumab emtansine (KadcylaTM), brentuximab vedotin (AdcetrisTM), inotuzumab ozogamicin (BesponsaTM), gemtuzumab ozogamicin (MylotargTM) and moxetumomab pasudotox-tdfk (Lumoxiti®)] and over 70 others are in various stages of clinical development, with impressive interim results being reported for many. The technology is based on the concept of delivering a cytotoxic payload selectively to cancer cells by attaching it to an antibody targeted to antigens on the cell surfaces. This approach has several advantages including the ability to select patients as likely responders based on the presence of antigen on the surface of their cancer cells and a wider therapeutic index, given that ADC targeting enables a more efficient delivery of cytotoxic agents to cancer cells than can be achieved by conventional chemotherapy, thus minimising systemic toxicity. Although there are many examples of antibodies that have been developed for this purpose, along with numerous linker technologies used to attach the cytotoxic agent to the antibody, there is presently a relatively small number of payload molecules in clinical use. The purpose of this book is to describe the variety of payloads used to date, along with a discussion of their advantages and disadvantages and to provide information on novel payloads at the research stage that may be used clinically in the future.
Download or read book Calculating the Secrets of Life written by National Research Council and published by National Academies Press. This book was released on 1995-04-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: As researchers have pursued biology's secrets to the molecular level, mathematical and computer sciences have played an increasingly important roleâ€"in genome mapping, population genetics, and even the controversial search for "Eve," hypothetical mother of the human race. In this first-ever survey of the partnership between the two fields, leading experts look at how mathematical research and methods have made possible important discoveries in biology. The volume explores how differential geometry, topology, and differential mechanics have allowed researchers to "wind" and "unwind" DNA's double helix to understand the phenomenon of supercoiling. It explains how mathematical tools are revealing the workings of enzymes and proteins. And it describes how mathematicians are detecting echoes from the origin of life by applying stochastic and statistical theory to the study of DNA sequences. This informative and motivational book will be of interest to researchers, research administrators, and educators and students in mathematics, computer sciences, and biology.
Download or read book Some Antiviral and Antineoplastic Drugs and Other Pharmaceutical Agents written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by World Health Organization. This book was released on 2000 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluates the carcinogenic risks to humans posed by the use of four antiretroviral agents four DNA topoisomerase II inhibitors used in the treatment of cancer and an additional three pharmaceutical agents (hydroxyures phenolphthalein and vitamin K substances). The volume marks the first IARC evaluation of nucleoside analogs that act as antiviral agents. The evaluation responds in part to recent findings that zidovudine (AZT) an effective antiretroviral agent now being given to pregnant HIV-infected women to prevent maternal-to-fetal transmission of the virus is a transplacental carcinogen in mice. The opening monograph evaluates the carcinogenicity to humans of the antiretroviral nucleoside analogs zidovudine (AZT) zalcitabine (ddC) and didanosine (ddI) and the antiherpesvirus drug aciclovir. Of these aciclovir and didanosine could not be classified on the basis of available data. For zidovudine transplacental administration to mice resulted in an increased incidence and multiplicity of lung and liver tumours and in an increased incidence of female reproductive tract tumours in one study but not in another involving treatment at a lower dose. Despite observation of toxic effects in some studies of humans human carcinogenicity data were judged to provide inadequate evidence of carcinogenicity in humans. Zidovudine was classified as possibly carcinogenic to humans. Similar weaknesses in human carcinogenicity data for zalcitabine which consistently induces thymic lymphomas in mice resulted in its classification as possibly carcinogenic to humans. The second monograph evaluates four DNA topoisomerase II inhibitors: etoposide teniposide mitoxantrone and amsacrine. Of these etoposide - one of the most widely used and effective cytotoxic drugs in combination therapy - was classified as probably carcinogenic to humans and etoposide in combination with cisplatin and bleomycin was judged to be carcinogenic to humans. Teniposide was classified as probably carcinogenic to humans and mitoxantrone and amsacrine were classified as possibly carcinogenic to humans. Of the three pharmaceutical agents evaluated in the final monograph hydroxyurea which is widely used in cancer treatment and increasingly in combination with didanosine in HIV infection could not be classified. Phenolphthalein a widely used laxative now being withdrawn from the market in many countries because of toxicological concerns was classified as possibly carcinogenic. Vitamin K substances could not be classified on the basis of available evidence.
