This text highlights seminal discoveries and also provides comprehensive and state-of the-art approach to mouse models of human patient tumors. These areas include training, basic techniques, as well as general troubleshooting. Subsequent chapters focus on the different mouse models of patient tumors including the various strains of immunodeficient mice currently available and the transplantation techniques that can be used as well as state-of-the-art imaging techniques. Practical applications of the models from drug discovery, genome analysis to personalized treatment are also covered. Written by experts in that field, each of these sections address these critical issues. A brief review of the existing literature addressing the particular topic follows in each section. Presently, there is no single source to provide information on technique and uses of mouse models of human patient tumors. Patient-Derived Mouse Models of Cancer will satisfy this need for cancer researchers, oncologists, pharmaceutical and biotechnology industry scientists as well as molecular biologists studying in vivo systems

This book describes recent advances in translational research in breast cancer and presents emerging applications of this research that promise to have meaningful impacts on diagnosis and treatment. It introduces ideas and materials derived from the clinic that have been brought to "the bench" for basic research, as well as findings that have been applied back to "the bedside". Detailed attention is devoted to breast cancer biology and cell signaling pathways and to cancer stem cell and tumor heterogeneity in breast cancer. Various patient-derived research models are discussed, and a further focus is the role of biomarkers in precision medicine for breast cancer patients. Next-generation clinical research receives detailed attention, addressing the increasingly important role of big data in breast cancer research and a wide range of other emerging developments. An entire section is also devoted to the management of women with high-risk breast cancer. Translational Research in Breast Cancer will help clinicians and scientists to optimize their collaboration in order to achieve the common goal of conquering breast cancer.
The Nude Mouse in Experimental and Clinical Research presents the state of knowledge regarding the nude mouse and its applications to different branches of scientific research. The research studies featured in this book emphasize the academic status of a broad range of subjects and techniques of nude mouse research. The text consists of 21 chapters, each discussing an important aspect of nude mouse research. Some chapters discuss the biological aspect such as physiology, genes, and breeding and mass production of the mouse. A number of the chapters also discuss the general observations of the mouse like histopathological observations and their background. The applications of the nude mouse to human tumor and cancer cell research are likewise given emphasis. This book will be of valuable importance to both students and researchers in the fields of medicine, biology, and pathology.
Non-thermal irreversible electroporation is a new minimally invasive surgical p- cedure with unique molecular selectivity attributes – in fact it may be considered the first clinical molecular surgery procedure. Non-thermal irreversible electro- ration is a molecular selective mode of cell ablation that employs brief electrical fields to produce nanoscale defects in the cell membrane, which can lead to cell death, without an effect on any of the other tissue molecules. The electrical fields can be produced through contact by insertion of electrode needles around the undesirable tissue and non-invasively by electromagnetic induction. This new - dition to the medical armamentarium requires the active involvement and is of interest to clinical physicians, medical researchers, mechanical engineers, che- cal engineers, electrical engineers, instrumentation designers, medical companies and many other fields and disciplines that were never exposed in their training to irreversible electroporation or to a similar concept. This edited book is designed to be a comprehensive introduction to the field of irreversible electroporation to those that were not exposed or trained in the field before and can also serve as a reference manual. Irreversible electroporation is broad and interdisciplinary. Therefore, we have made an attempt to cover every one of the various aspects of the field from an introductory basic level to state of the art.
Cancer cell biology research in general, and anti-cancer drug development specifically, still relies on standard cell culture techniques that place the cells in an unnatural environment. As a consequence, growing tumor cells in plastic dishes places a selective pressure that substantially alters their original molecular and phenotypic properties.The emerging field of regenerative medicine has developed bioengineered tissue platforms that can better mimic the structure and cellular heterogeneity of in vivo tissue, and are suitable for tumor bioengineering research. Microengineering technologies have resulted in advanced methods for creating and culturing 3-D human tissue. By encapsulating the respective cell type or combining several cell types to form tissues, these model organs can be viable for longer periods of time and are cultured to develop functional properties similar to native tissues. This approach recapitulates the dynamic role of cell–cell, cell–ECM, and mechanical interactions inside the tumor. Further incorporation of cells representative of the tumor stroma, such as endothelial cells (EC) and tumor fibroblasts, can mimic the in vivo tumor microenvironment. Collectively, bioengineered tumors create an important resource for the in vitro study of tumor growth in 3D including tumor biomechanics and the effects of anti-cancer drugs on 3D tumor tissue. These technologies have the potential to overcome current limitations to genetic and histological tumor classification and development of personalized therapies.

Chapters focus on subpopulations of cells with stem-like properties, laser capture microdissection, and modeling human glioma with human embryonic stem cells. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Glioblastoma: Methods and Protocols aims to support researchers seeking new and refined protocols to better decrypt this tumor.
Abstract: Objectives Gastric cancer (GC) is an aggressive disease due to late diagnosis resulting from the lack of easy diagnostic tools, resistances toward immunotherapy (due to low PD-L1 expression), or chemotherapies (due to p53 mutations), and comorbidity factors, notably muscle atrophy. To improve our understanding of this complex pathology, we established patient-derived xenograft (PDX) models and characterized the tumor ecosystem using a morpho-functional approach combining high-resolution imaging with molecular analyses, regarding the expression of relevant therapeutic biomarkers and the presence of muscle atrophy. Materials and methods GC tissues samples were implanted in nude mice. Established PDX, treated with cisplatin or not, were imaged by magnetic resonance imaging (MRI) and analyzed for the expression of relevant biomarkers (p53, PD-L1, PD-1, HER-2, CDX2, CAIX, CD31, a-SAM) and by transcriptomics. Results Three well-differentiated, one moderately and one poorly differentiated adenocarcinomas were established. All retained the architectural and histological features of their primary tumors. MRI allowed in-real-time evaluation of differences between PDX, in terms of substructure, post-therapeutic changes, and muscle atrophy. Immunohistochemistry showed differential expression of p53, HER-2, CDX2, a-SAM, PD-L1, PD-1, CAIX, and CD31 between models and upon cisplatin treatment. Transcriptomics revealed treatment-induced hypoxia and metabolic reprograming in the tumor microenvironment. Conclusion Our PDX models are representative for the heterogeneity and complexity of human tumors, with differences in structure, histology, muscle atrophy, and the different biomarkers making them valuable for the analyses of the impact of platinum drugs or new therapies on the tumor and its microenvironment
