Successful cancer chemotherapy relies heavily on the application of various deoxynucleoside analogs. Since the very beginning of modern cancer chemotherapy, a number of antimetabolites have been introduced into the clinic and subsequently applied widely for the treatment of many malignancies, both solid tumors and hematological disorders. In the latter diseases, cytarabine has been the mainstay of treatment of acute myeloid leukemia. Although many novel compounds were synthesized in the 1980s and 1990s, no real improvement was made. However, novel technology is now capable of elucidating the molecular basis of several inborn errors as well as some specific malignancies. This has enabled the synthesis of several deoxynucleoside analogs that could be applied for specific malignancies, such as pentostatin and subsequently chlorodeoxyadenosine (cladribine) for the treatment of hairy cell leukemia. Already in the early stage of deoxynucleoside analog development, it was recognized that several of these compounds were very effective in the treatment of various viral infections, such as for the treatment of herpes infections. This formed the basis initially for the design of azidothymidine and subsequently many other analogs, which are currently successfully used for the treatment of HIV infections. As a spin-off of these research lines, some compounds not eligible for development as antiviral agents appeared to be very potent anticancer agents. The classical example is gemcitabine, now one of the most widely applied deoxynucleoside analogs, used for the (combination) treatment of non-small cell lung cancer, pancreatic cancer, bladder cancer, and ovarian cancer.

The epidermal gro wth factor (EGF ) receptor and its downstream signal transduction networks have been implicated in the ontology and maintenance of tumor tissues, which has motivated the discovery and development of molecularly targeted anti-EGF receptor therapies. Over decades of study, the EGF receptor structure, its ligand binding domains, the physical biochemistry underlying its intrinsic tyrosine kinase catalytic function and the modular interactions with SH2, PTB, and SH3 domain containing signaling adaptor p- teins required for signal transduction, have been extensively dissected. Not only is the EGF receptor the nexus of many streams of information, but it also forms one part of a calcul- ing device by forming dimers and oligomers with the other three receptors in its family in response to at least eleven ligands (some of which are expressed in multiple forms with overlapping or quite distinct functions). This phenomenon, while recruiting to the inner surface of the cell membrane and activating multiple second messenger proteins, also allows the possibility of cross talk between these systems, permitting a further layer of information to be exchanged. Less well described are the cross re gulation of the EGF receptor and other anti-apoptotic, mitogenic and metabolic signaling systems. The study of these systems has yielded new surprises. One hurdle in these efforts has been that signal transduction pathways have frequently been defined in the generic absence of their tissue-specific or cell-interaction specific context.

Extensive research has uncovered a set of molecular surveillance mechanisms – commonly called “checkpoints” – which tightly monitor cell-cycle processes. Today’s anticancer drug development has identified many of these cell-cycle checkpoint molecules as effective targets. Research now promises to uncover a new generation of anticancer drugs with improved therapeutic indices based on their ability to target emerging checkpoint components. Checkpoint Responses in Cancer Therapy summarizes the advances made over the past 20 years, identifying components of cell-cycle checkpoints and their molecular regulation during checkpoint activation and validating the use of checkpoint proteins as targets for the development of anticancer drugs. This book’s distinguished panel of authors takes a close look at topics ranging from the major molecular players affecting DNA synthesis and the response to DNA damage to advances made in the identification of chemical compounds capable of inhibiting individual mitotic kinases. Illuminating and authoritative, Checkpoint Responses in Cancer Therapy offers a critical summary of findings for researchers in the pharmaceutical and biotechnology industries and a valuable resource for academic scientists in cancer research and the study of cell-cycle regulation, signal transduction and apoptosis.

Leading experts summarize and synthesize the latest discoveries concerning the changes that occur in tumor cells as they develop resistance to anticancer drugs, and suggest new approaches to preventing and overcoming it. The authors review physiological resistance based upon tumor architecture, cellular resistance based on drug transport, epigenetic changes that neutralize or bypass drug cytotoxicity, and genetic changes that alter drug target molecules by decreasing or eliminating drug binding and efficacy. Highlights include new insights into resistance to antiangiogenic therapies, oncogenes and tumor suppressor genes in therapeutic resistance, cancer stem cells, and the development of more effective therapies. There are also new findings on tumor immune escape mechanisms, gene amplification in drug resistance, the molecular determinants of multidrug resistance, and resistance to taxanes and Herceptin.

"Over the past 20 years, there have been tremendous advances in our understanding of how normal cells transform to cancer and the importance of signaling pathways in cancer initiation and progression. To keep pace, proteomics technologies must constantly be improved. In Cancer Proteomics, the authors collectively outline the current status of proteomics in cancer therapy and describe the existing technologies used in proteomics that allow for protein profiling and the identification of druggable targets in human samples. Mass spectrometry-based protein characterization and protein microarrays hold great promise for predicting response to specific drugs in cancer therapy. This book offers a broad perspective on topics related to the use of proteomic strategies in cancer therapy and addresses challenges that may arise from its application in daily practice."--Jacket.

Genomics and Pharmacogenomics in Anticancer Drug Development and Clinical Response provides the most comprehensive body of knowledge available on the role of genetic and genomic variation in the individualization of drug therapies in cancer patients. As a consequence of the intrinsic chromosomal and genetic instability of the tumor genome, it is generally believed that tailoring of chemotherapy in cancer - tients might be achieved by molecular analysis of patient tumor DNA. In addition, to reduce the toxicity risk of patients, the tumor DNA information should be in- grated with the available data on polymorphic drug-metabolizing enzyme and tra- porter genes mediating the exposure of patients to active drugs and/or their active metabolites. The chapters of this book clearly show how DNA information from both the host (germline) and the tumor should be taken into account for rational selection of drug therapies in cancer patients, an aspect that received little attention, despite its importance. The availability of new molecular approaches to the selection of drug therapy is an emerging need, because the traditional approach based on the evaluation of patient and tumor characteristics is clearly far from optimal. Many treated patients do not experience signi?cant bene?ts from the treatment, while they often experience moderate to severe toxicities. In addition, the development and clinical use of novel molecularly targeted agents (alone or in combination with classical cytotoxic therapy) requires the und- standing of the molecular features of the tumors and the identi?cation of tumor markers of response.

Phycotoxins are a diverse group of poisonous substances produced by certain seaweed and algae in marine and fresh waters. Marine toxins are important to the scientific community for many reasons, the most obvious being that they pose food safety issues which requires a large investment from producing countries to regularly monitor the presence of these compounds in foods. For centuries we have been aware that some edible marine products contain toxins or poisons, and therefore we only eat those that are safe. However, phycotoxins accumulate in fish and shellfish from their diet and these toxins are carried up the food chain in edible aquatic products, which can pose harm to people when they reach a certain level. The presence of marine and aquatic toxins is now identified in geographical areas where they were never detected before, which is becoming a concern for food safety authorities as the expansion of water toxins worldwide is a serious threat. The legal change on the standards to control marine toxins has brought about concerns with regard to what toxins are leaking to food and not being identified by food regulators. Since the publication of the first edition, there have been major advances in the science of marine and aquatic toxins, and advances in toxicology, analytical chemistry and pharmacology suggest an update is much needed. This fully revised and updated edition includes several new chapters, including those on Ciguatoxins, Pinnatoxin, Tetrodotoxin, as well as new chapters on food safety control of marine toxins, climate change and water toxins, and microalgae as a source of nutraceuticals. The book presents the most up to date information available on phycotoxins, giving major emphasis to chemistry and biochemistry but also covering aspects of origin, mechanism of action, toxicology and analytical methodology. Phycotoxins: Chemistry and Biochemistry, second edition, will be of interest to toxicologists, marine, food, and plant scientists, as well as researchers and academics in the areas of food science, medicine, public health, toxicology, pharmacology and marine biology.
