Book Description
Cellular signaling pathways are involved in numerous physiological processes such as reproduction, growth, and the development of cancer and chemoresistance. G-protein coupled receptors (GPCRs) are master regulators of many signaling pathways as they are expressed in numerous tissues types throughout the body. GPCRs are being investigated in cancer development particularly through their roles in angiogenesis, metastasis, and inflammation-associated cancer. Growth factors that bind and activate GPCRs to mediate signaling pathways involved in growth and survival include lysophosphatidic acid (LPA). In our studies, both in vitro and in vivo methods were used to test the importance of several signaling pathways in chemoresistant cancer cell survival and tumor biology. In our studies, we found that specific Regulators of G-protein signaling (RGS) proteins are involved in modulating growth and survival pathways in ovarian cancer. Specifically, we showed that silencing of RGS10 and RGS17 proteins increases viability of ovarian cancer cells, and we further examined the role of modulating RGS10 expression on cell differentiation, proliferation, and survival pathways. We also showed that the inhibition of autotaxin the enzyme that produces LPA is a potential therapeutic target for melanoma and how LPA mediated receptor pathways can be manipulated to overcome chemoresistance in cancer. Our most valuable observation was that our novel compounds were able to reduce tumor progression in vivo in a primary xenograft model of melanoma in correlation with a reduction in markers of angiogenesis. Our data serves to help better understand signaling pathways involved in the development of chemoresistance.

Book Description
One of the most exciting areas of cancer research now is the development of agents which can target signal transduction pathways that are activated inappropriately in malignant cells. The understanding of the molecular abnormalities which distinguish malignant cells from their normal counterparts has grown tremendously. This volume summarizes the current research on the role that signal transduction pathways play in the pathogenesis of cancer and how this knowledge may be used to develop the next generation of more effective and less toxic anticancer agents. Series Editor comments: "The biologic behavior of both normal and cancer cells is determined by critical signal transduction pathways. This text provides a comprehensive review of the field. Leading investigators discuss key molecules that may prove to be important diagnostic and/or therapeutic targets."

Book Description
Heat shock proteins are emerging as important molecules in the development of cancer and as key targets in cancer therapy. These proteins enhance the growth of cancer cells and protect tumors from treatments such as drugs or surgery. However, new drugs have recently been developed particularly those targeting heat shock protein 90. As heat shock protein 90 functions to stabilize many of the oncogenes and growth promoting proteins in cancer cells, such drugs have broad specificity in many types of cancer cell and offer the possibility of evading the development of resistance through point mutation or use of compensatory pathways. Heat shock proteins have a further property that makes them tempting targets in cancer immunotherapy. These proteins have the ability to induce an inflammatory response when released in tumors and to carry tumor antigens to antigen presenting cells. They have thus become important components of anticancer vaccines. Overall, heat shock proteins are important new targets in molecular cancer therapy and can be approached in a number of contrasting approaches to therapy.

Book Description
This volume presents information on both the basic and clinical aspects of sphingolipid-metabolizing enzymes in various cancers. The volume also includes discussions of the innovative techniques and approaches for quantitative analysis and imaging that could significantly impact the general understanding of this topic, and the potential benefit of targeting sphingolipid enzymes to develop novel cancer therapeutics. As well, the volume includes a critical examination of the specific pathways and pathobiologies associated with the altered regulation of sphingolipid metabolism as a contributor to the development and/or maintenance of pathological conditions such as cancer.

Book Description
This volume examines in detail the role of chronic inflammatory processes in the development of several types of cancer. Leading experts describe the latest results of molecular and cellular research on infection, cancer-related inflammation and tumorigenesis. Further, the clinical significance of these findings in preventing cancer progression and approaches to treating the diseases are discussed. Individual chapters cover cancer of the lung, colon, breast, brain, head and neck, pancreas, prostate, bladder, kidney, liver, cervix and skin as well as gastric cancer, sarcoma, lymphoma, leukemia and multiple myeloma.

Book Description
Chemotherapy is one of the major treatment options for cancer patients; however, the efficacy of chemotherapeutic management of cancer is severely limited by multidrug resistance, in that cancer cells become simultaneously resistant to many structurally and mechanistically unrelated drugs. In the past three decades, a number of mechanisms by which cancer cells acquire multidrug resistance have been discovered. In addition, the development of agents or strategies to overcome resistance has been the subject of intense study. This book contains comprehensive and up-to-date reviews of multidrug resistance mechanisms, from over-expression of ATP-binding cassette drug transporters such as P-glycoprotein, multidrug resistance-associated proteins, and breast cancer resistance p- tein to the drug ratio-dependent antagonism and the paradigm of cancer stem cells. The book also includes strategies to overcome multidrug resistance, from the development of compounds that inhibit drug transporter function to the modulation of transporter expression. In addition, this book contains techniques for the detection and imaging of drug transporters, methods for the investigation of drug resistance in animal models, and strategies to evaluate the efficacy of resistance reversal agents. The book intends to provide a state-of-the-art collection of reviews and methods for both basic and clinician investigators who are interested in cancer multidrug resistance mechanisms and reversal strategies.

Book Description
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Book Description
This volume will bring together a review of research being carried out by international experts in this field, detailing treatment and research approaches in several forms of malignant brain tumors. These include glioblastoma (GBM), a highly aggressive and fatal form of astrocytoma which accounts for 80% of newly diagnosed brain tumor patients per year, and meningioma, of which 10% are malignant and extremely resistant to targeted therapies. The volume will also include a discussion of methods to overcome blood-brain barrier exclusion for more efficient targeted drug delivery in all forms of brain cancer treatment. The volume will include information on the repurposing of drugs in an attempt to circumvent drug resistance, use of small molecule inhibitors in GBM treatment, mechanisms of secondary brain metastasis, drug resistance, and state-of-the-art imaging of targeted therapies.
