The use of exocyclic adducts as biomarkers offers a promising tool in studies of cancer etiology and prevention, particularly for human neoplasias in which the causative factors and mechanisms are still poorly understood. Presentations at an international conference, which resulted in this volume, comprise a comprehensive treatise on the current state of the art and scientific information on exocyclic DNA adducts. The volume includes sections on ultra sensitive detection methods, formation from exogenous and endogenous sources, DNA repair, physical chemical approaches to structural elucidation, and use as biomarkers and their role in mutagenesis and carcinogenesis.

The chemicals discussed here include possible or identified human carcinogens, chemotherapeutic agents, and a number of mutagenic substances for which human exposure is known to occur. More than 40 presentations cover occurrence, epidemiology, and carcinogenic affects; chemistry and formation of cyclic and other adducts; metabolism; biological effects; mechanistic approaches; and sensitive methods for detection of nucleic acid adducts. For oncologists, specialists in occupational health, and biochemists.

Numerous physical and chemical stress factors, endogenous or exogenous, challenge living organisms. Metabolisation processes generate highly reactive intermediates which can covalently bind to DNA, resulting in bulky addition products called "adducts." DNA adduct formation appears to be a general response of plants to organic chemical exposure, whether in controlled conditions or in the field. In particular, common carcinogenic pollutants and pesticides promote the formation of DNA adducts in plants. The authors of this book examine the development of DNA adducts, as well as the ways in which they can be eliminated due to DNA repair pathways. In this book, the data from in vivo transgenic assays is also examined, which can help to clarify specific pre-mutagenic adducts, DNA repair functions and mutational events that may be involved in the mutagenicity of human carcinogens. Other chapters in this book identify and discuss novel anthracyclines capable of forming DNA adducts, the role of DNA adducts as early biomarkers in the screening and development of marine anticancer drugs, the genotoxicity, such as DNA adduct formation, of air pollutants and its assessment by in vivo mutagenesis and a discussion of oxidative DNA damage, which can play an important role in the carcinogenic processes of PAHs and aromatic amines, in addition to bulky-DNA adducts formation.

Concern is often expressed that our environment may include an increasingly large variety of mutagens, but the extent of the potential hazard they pose has yet to be fully evaluated. A variety of empirical procedures has been devised with which to estimate the mutagenic potency of suspect agents, and the relative merits of different tests are currently under debate. Although such tests are of great value, and are indeed indispensable, they are not, nevertheless, sufficient. In the long term, accurate estimation of hazard will also require a better understanding of the various mechanisms of mutagenesis, and in many instances these remain remarkably elusive. Our knowledge and appreciation of the problem has increased substantially over the last few years, but the precise way in which many mutagens cause mutations is not yet known. The aims of this conference were therefore two-fold. The first was to survey present information about mutagenic mechanisms, drawing together data from work with various experimental approaches and organisms, in order to discern the principles governing the action of different mutagens. The second was to examine the implications of such principles for the execution and evaluation of test procedures, and critically assess the research areas that need further attention in order to improve the interpretation of test results.

Molecular Life Sciences: An Encyclopedic Reference will focus on understanding biological phenomena at the level of molecules and their interactions that govern life processes. The work will include articles on genes and genomes, protein structure and function, systems biology using genomics and proteomics as the focus, molecular aspects of cell structure and function, unifying concepts and theories from biology, chemistry, mathematics and physics that are essential for understanding the molecular life sciences (including teaching perspectives and assessment tools), and basic aspects of the various experimental approaches that are used in the Molecular Life Sciences.
