This book was released on 2016 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The metastatic cascade comprises of a series of events, which tumor cells must complete to form macrometastases at a secondary site. Due to its spread and aggressive nature, metastatic tumor is difficult to treat, and tumor metastasis remains the main cause of death in cancer patients. Most epithelial tumors over-express tissue factor (TF), the initiator of the extrinsic pathway of coagulation cascade. This over-expression of TF has been shown to tumor progression and metastasis in different studies. In this thesis, we studied two mechanisms by which tumor-derived TF can interact with endothelial cells to promote cancer metastasis. Endothelial cells act as a natural barrier between the tumor cells in circulation and secondary organs. Tumor cells must arrest on endothelial cells in order to extravasate and enter a new organ. Most previous studies have focused on the classical receptor-ligand interactions involved in leukocyte recruitment during inflammation, such as selectins and integrins. We hypothesized that TFexpressing tumor cells can mediate adhesion to the endothelium by interacting with its endogenous inhibitor, tissue factor pathway inhibitor (TFPI), which is constitutively expressed on endothelial cells. Using in vitro models, we found that high TF-expressing tumor cells bound to recombinant TFPI and endothelial cells under static conditions; however, under shear, the tumor cells adhered to recombinant TFPI, but not endothelial cells. We postulate that the TFPI expres- sion in our endothelial cell model (human umbilical vein) was too low to mediate adhesion. Unfortunately, due to the lack of availability of other primary endothelial cells that express higher TFPI (e.g. lung microvascular endothelium), we could not test this theory further. Endothelial cells, highly dynamic and responsive to its local environment, perform a range of functions in the body. Endothelial responses could be hijacked by tumor cells to promote a tumor-permissive metastatic environment. Tumor cells secrete extracellular vesicles (EV) that can interact with distant cells and re-educate them to a pro-tumor phenotype. Tumor cells secrete two types of EV - microvesicles (100-1000nm) and exosomes (30-100nm). In this part of the thesis, we evaluated the isolation of exosomes and microvesicles using common established protocols - filtration and differential centrifugation. We found that the isolation methods highly impacted the size distribution, the purity and TF-mediated procoagulant activity in the isolated fractions. We then evaluated whether tumor-derived TF-expressing EV (consist of microvesicles and exosomes) promote pro-metastatic behaviors in endothelial cells in vitro. We observed binding and uptake of EV by endothelial cells. These EV also signaled to endothelial cells and promoted a pro-adhesive (upregulation of E-selectin and intercellular cellular adhesion molecule-1), pro-inflammatory (increased secretion of monocyte chemotactic protein-1 and interleuking-8) and procoagulant (increase in TF-mediated procoagulant activity) phenotype in endothelial cells. The mechanism was dependent on TF-mediated FXa generation by EV, and activation of protease-activated receptor-1 followed by transactivation of epidermal growth factor receptor on endothelial cells.

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.

Book Synopsis Tumor Invasion and Metastasis by : L.A. Liotta
Download or read book Tumor Invasion and Metastasis written by L.A. Liotta and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: The clinical significance of tumor spread has always been appreciated. Yet, in spite of the pioneering work and outstanding contributions of investigators such as D. Coman, H. Green, B. Fisher, S. Wood and I. Zeidman, studies on metastasis rarely achieved the popularity afforded to more esoteric areas of tumor biology. Tumor dissemination, occurring as it does in a responding host and being composed of a series of dynamic int~ractions, is a highly complex phenomenon. Few investigators were brave enough to attempt to unravel the mechanisms involved. Paradoxically, this very complexity may have contributed, in part, to the recent upsurge of interest in metastasis research. More and more researchers are becoming fascinated by the complexities of the cellular interactions involved in tumor spread. Accompanying this intellectual stimulation have been technological advances in related fields which allow the derivation of new model systems. The mechanisms of metastatic spread are increasingly amenable to both the reductionist and holistic approaches and it is the purpose of this volume to present many of these model systems while emphasizing the intricacy and complexity of the processes they mimic. We have attempted to emphasize two topics not previously covered in depth in previous books on metastases. These are in vitro models of invasion and in teractions of tumor cells with connective tissue.

Book Synopsis Intercellular Communication in Cancer by : Mustapha Kandouz
Download or read book Intercellular Communication in Cancer written by Mustapha Kandouz and published by Springer. This book was released on 2015-11-20 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells are by nature compelled to live in groups. They develop dependence over signaling cues received from their microenvironment, in particular from other cells, whether of their own “kind” or of a different type. Therefore, communicating with these cells is a critical aspect of their behavior and fate, as they live and die normally or as they undergo disease-related pathological changes, with dramatic repercussions. In this book, we have asked expert researchers in the field of Intercellular Communication in Cancer to provide chapters on different aspects of interaction between neighboring cells, in the context of cancer diseases. We have specifically focused our efforts on membrane-to-membrane contact-based rather than growth factors-mediated modes of intercellular communications. The contributing authors provide an extensive overview of their respective area of specialization, with an in-depth discussion of the molecular mechanisms of cell-cell interactions, the impact on tumor progression and response to therapies, as well as the cancer diagnostic value of this scientific information. This book aims to introduce essential aspects of the normal and pathological cellular fate and homeostasis to both scientists and clinicians, and also to provide established researchers with an update on the novelties and future directions this expanding field is witnessing.
