Book Synopsis Dissecting the Molecular Mechanisms of Therapeutic Resistance in Cancer by : Vibhuti Agrawal

Available in PDF, EPUB and Kindle. Book excerpt: Therapeutic resistance continues to be a persistent challenge in medical oncology. In clinical settings, resistance can occur at the beginning of treatment, or may be acquired after an initial clinical response to the therapy. Several mechanisms of drug resistance have been described in cancer, including alterations in the drug transport and metabolism process, mutations in drug-target, activation of bypass signaling pathways, inhibition of cell-death pathways, and induction of an epithelial to mesenchymal transition (EMT) in response to cytotoxic or targeted therapies. In this study, I have investigated the molecular mechanisms underlying ZEB 1-induced EMT and established a new computational framework that uses inter-animal heterogeneity to identify drivers responsible for variable phenotypic responses across different animals. EMT describes a cell-state switching process wherein epithelial cells lose their tight cell-cell junction contacts, and acquire the ability to migrate and invade the surrounding stroma to enter into blood circulation. Given the widespread role of EMT in drug resistance, it is imperative to identify therapeutic strategies to inhibit this transition. To identify druggable targets to block EMT progression, and therefore overcome EMT-mediated therapeutic resistance, I studied the effects of ZEB 1 expression on cellular signaling networks. By quantifying changes in tyrosine phosphorylation at different time points during ZEB 1-induced EMT, I found that Src family kinases (SFKs) were activated within 24 hours of ZEB 1 expression. Inhibition of SFKs blocked not only ZEB 1-induced EMT, but also EMT initiated by TGFp- and EGF signaling pathways in both breast and NSCLC cell-lines. SFK inhibition also prevented EGFR inhibitor-induced EMT and drug resistance in NSCLC cells both in vitro and in vivo. Mechanistically, SFK activation stabilized ZEBI by promoting ERK1/2-mediated phosphorylation on three serine residues, S583, S646, and S679. Consequently, MEK inhibition phenocopied the effects of blocking SFK activity with regards to decreasing stability of ZEB 1 and inhibiting ZEB 1-induced EMT. These results provide a new therapeutic application of SFK inhibitors as a potential anti-EMT therapy, to enhance the susceptibility of cancer cells to chemo- or targeted therapies. In the second part of this thesis, I have described a computational framework that leverages inter-animal heterogeneity to identify molecular mechanisms underlying variable phenotypic responses across different animals. Substantial inter-animal variability in phenotypes within the same treatment group, limits our ability to draw conclusions or gain meaningful insights about a biological process by simply averaging the data. To identify molecular drivers for heterogeneous phenotypic responses, I have established a method where each animal is considered as an individual entity whose phenotypic response is dependent on the state of its underlying signaling networks. As a proof of concept, I have used this method to successfully predict the resistance mechanisms of CDK4/6 inhibitor, palbocilib in two GBM PDX and one MPNST PDX models. The GBM6 model activated EGFR signaling upon treatment with palbociclib whereas the GBM22 and MPNST3 models activated SFKs and PDGFRa signaling in resistant tumors. Across all three PDX tumor models, treatment with combination therapies, consisting of palbociclib and an inhibitor targeting the activated bypass signaling pathway, substantially prolonged survival of mice. Thus, these results suggest that inter-animal variability can be used as a tool to predict drivers for a specific phenotypic response across different treatment conditions.

Book Synopsis Metastatic Cancer: Clinical and Biological Perspectives by : Rahul Jandial
Download or read book Metastatic Cancer: Clinical and Biological Perspectives written by Rahul Jandial and published by CRC Press. This book was released on 2013-08-08 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most cancer deaths are a result of metastasis. The spread of a primary tumor to colonize neighboring and distant organs is the relentless endgame that defines the neoplastic process. Patients who have been diagnosed with cancer are treated to prevent both the recurrence of the tumor at the site of origin and metastasis that would re-stage them as advanced stage IV cancer. Historically and still with some types of cancer, stage IV is perceived by patients as “terminal.” Fortunately, recent molecular therapies have extended the lives of patients with advanced cancer and reassuringly people living with metastatic disease increasingly visit our clinics. What is the path forward? Given that the consilience of science and medicine is a dynamic art from which therapies arise, it would be misguided to consider any single work adequate at capturing the horizon for research. So with humility we constructed this text as primer for scientists. It begins with a broad introduction to the clinical management of common cancers. This is intended to serve as a foundation for investigators to consider when developing basic science hypotheses. Unquestionably, medical and surgical care of cancer patients reveals biology and dictates how novel therapeutics will ultimately be evaluated in clinical trials. The second section of this text offers provocative and evolving insights that underscore the breadth of science involved in the elucidation of cancer metastasis biology. The text concludes with information that integrates scientific and clinical foundations to highlight translational research. This book serves as a framework for scientists to conceptualize clinical and translational knowledge on the complexity of disease that is metastatic cancer.

This book was released on 2012-05-29 with total page 847 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridging the gap between research and clinical application, Biosensors and Molecular Technologies for Cancer Diagnostics explores the use of biosensors as effective alternatives to the current standard methods in cancer diagnosis and detection. It describes the major aspects involved in detecting and diagnosing cancer as well as the basic elements of biosensors and their applications in detection and diagnostics. The book addresses cancer molecular diagnostics, including genomic and proteomic approaches, from the perspective of biosensors and biodetection. It explains how to measure and understand molecular markers using biosensors and discusses the medical advantages of rapid and accurate cancer diagnostics. It also describes optical, electrochemical, and optomechanical biosensor technologies, with a focus on cancer analysis and the clinical utility of these technologies for cancer detection, diagnostics, prognostics, and treatment. Making biosensor technology more accessible to molecular biologists, oncologists, pathologists, and engineers, this volume advances the integration of this technology into mainstream clinical practice. Through its in-depth coverage of a range of biosensors, the book shows how they can play instrumental roles in the early molecular diagnosis of cancer.

Book Synopsis Monoclonal Antibodies in Cancer by : Stewart Sell
Download or read book Monoclonal Antibodies in Cancer written by Stewart Sell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This represents the third volume in a series on cancer markers pub lished by the Humana Press. The first volume, published in 1980, stressed the relationship of development and cancer as reflected in the production of markers by cancer that are also produced by normal cells during fetal development. The concept that cancer represents a problem of differentiation was introduced by Barry Pierce in describing differenti ation of teratocarcinomas. Highlighted were lymphocyte markers, alphafetoprotein, carcinoembryonic antigen, ectopic hormones, enzymes and isozymes, pregnancy proteins, and fibronectin. The second volume, published in 1982 and coedited with Britta Wahren, focused on the diagnostic use of oncological markers in human cancers, which were systematically treated on an organ by organ basis. At that time, the application of monoclonal antibodies to the identification of cancer markers was still in a very preliminary stage. A general introduc tion to monoclonal antibodies to human tumor antigens was given there by William Raschke, and other authors included coverage of those mark ers then detectable by monoclonal antibodies in their chapters.
Book Synopsis Metabolism in Cancer by : Thorsten Cramer
Download or read book Metabolism in Cancer written by Thorsten Cramer and published by Springer. This book was released on 2016-08-24 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook presents concise chapters written by internationally respected experts on various important aspects of cancer-associated metabolism, offering a comprehensive overview of the central features of this exciting research field. The discovery that tumor cells display characteristic alterations of metabolic pathways has significantly changed our understanding of cancer: while the first description of tumor-specific changes in cellular energetics was published more than 90 years ago, the causal significance of this observation for the pathogenesis of cancer was only discovered in the post-genome era. The first 10 years of the twenty-first century were characterized by rapid advances in our grasp of the functional role of cancer-specific metabolism as well as the underlying molecular pathways. Various unanticipated interrelations between metabolic alterations and cancer-driving pathways were identified and currently await translation into diagnostic and therapeutic applications. Yet the speed, quantity, and complexity of these new discoveries make it difficult for researchers to keep up to date with the latest developments, an issue this book helps to remedy.
