Available in PDF, EPUB and Kindle. Book excerpt: Breast cancer is fundamentally a disease of aberrant differentiation. Breast cancers arise from within the normal architecture of the mammary gland and resemble normal mammary epithelial cell types on a molecular and gene expression level. Many tumors become dependent on the signaling pathways that guide mammary differentiation and proliferation, and may be driven by transcription factors and signaling pathways that enforce cell state. It's no wonder then that many fundamental insights into breast cancer biology derive from study of the normal mammary gland. Mouse models of mammary gland development have helped identify many of the key genetic and hormonal drivers of mammary differentiation. However, these systems have some limitations. First, study of stem and progenitor cell differentiation decisions has been hampered by a lack of definitive markers of cell state. Second, validation of these pathways in human mammary tissue has been challenging due to a paucity of human model systems. This thesis describes work to overcome these limitations. Here I describe a computational method to identify regulators of cell state transitions without the need for definitive markers of cell state. Using this method, we identified RUNXI as a regulator of mammary stem cell differentiation, and demonstrated that RUNX1 is required for exit from the stem/progenitor state. RUNX1 inhibition expanded the pool of stem cells and blocked mammary morphogenesis. This thesis also describes the development of a 3D hydrogel culture system that supports the growth of primary human mammary epithelial tissues. The tissues exhibit all major cell types found in the mammary gland and are hormone responsive. We further adapted the culture system to study the early stages of breast cancer progression by injecting tumor cells into the tissues. Tumor cells interacted and intercalated with normal mammary epithelial cells before invading out of the tissues. We utilized this system to validate SMARCE1 as a regulator of human breast cancer progression. SMARCE1 expression is predictive of progression in early-stage epithelial tumors, and SMARCE1 is functionally required for basement membrane degradation. In our tissue model of tumor progression SMARCE1 was dispensable for cell growth and in situ spreading but was required for invasion.

This book was released on 2018 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mammary gland is unique among human tissues in that the bulk of its development occurs postnatally, under hormonal control. The gland consists of an epithelium that expands dramatically during puberty and pregnancy, and is the site of breast cancer initiation. Important connections between normal developmental signaling and breast cancer biology are evidenced by the molecular similarities between tumors and normal cell types. Thus, understanding how mammary differentiation is regulated has long been a goal in oncology and developmental biology. Researchers have relied on animal models and in vitro assays to study mammary development for decades. However, differences between the human and murine gland, from the morphology of the epithelium to the composition of the stroma, limit the utility of mouse models. Likewise, in vitro assays subject cells to non-physiological conditions that dramatically affect their behavior. In addition, the majority of experimental approaches used to study the cell states and differentiation regulators have relied on a candidate-based approach. While these studies have explored the roles of signaling pathways such as Wnt, which have known functions in other tissue-specific stem cell states, unbiased strategies to identify cell state regulators have been lacking. For these reasons, I have developed new experimental tools and unbiased strategies to identify genes that regulate mammary development and differentiation. In this thesis, I describe the development of a novel 3D tissue culture system that uses a hydrogel formulated to closely mimic the human stroma. This hydrogel provides a physiological context to study tissue development and processes like ductal initiation and branching morphogenesis, in real time. I also describe two studies that utilized unbiased methods to identify regulators of mammary stem cells and differentiation. The first study identified BCL1 lB as a driver of mammary stem cell self-renewal by inhibiting basal lineage commitment. The second study found that the collagen receptor, DDR1, is required for mammary stem cell differentiation into mature basal cell states, and that this process also drives luminal differentiation through interlineage Notch signaling. These studies provide a new set of tools to better understand human mammary biology, and further our understanding and treatment of breast cancer.

This book was released on 2000-07-06 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: In November 1999, the Institute of Medicine, in consultation with the Commission on Life Sciences, the Commission on Physical Sciences, Mathematics, and Applications, and the Board on Science, Technology and Economic Policy launched a one year study on technologies for early detection of breast cancer. The committee was asked to examine technologies under development for early breast cancer detection, and to scrutinize the process of medical technology development, adoption, and dissemination. The committee is gathering information on these topics for its report in a number of ways, including two public workshops that bring in outside expertise. The first workshop on "Developing Technologies for Early Breast Cancer Detection" was held in Washington DC in February 2000. The content of the presentations at the workshop is summarized here. A second workshop, which will focus on the process of technology development and adoption, will be held in Washington, DC on June 19-20. A formal report on these topics, including conclusions and recommendations, will be prepared by the committee upon completion of the one-year study.

Available in PDF, EPUB and Kindle. Book excerpt: Mammary Tumor Cell Cycle, Differentiation and Metastasis is the fifth volume since 1988 in a series designed to broadly examine current advances in the cellular and molecular biology of breast cancer. As in previous volumes, the editors have invited recognized experts in cutting-edge topics to provide a chapter focused on their area of research. The editors have turned to the researchers who study rodent models of the disease and to those who study the cellular and molecular basis of human breast cancer. The first section of the book is devoted to new mouse models of mammary development and tumorigenesis. The second section moves to studies of human breast cancer and focuses on receptors, signalling, and the cell cycle. The final section deals with defective tissue interactions in human breast cancer. We are now in a period of extremely rapid accumulation of data on the molecular and cellular biology of breast cancer. These findings are highlighted in chapters from Mammary Tumor Cell Cycle, Differentiation and Metastasis: Advances in Cellular and Molecular Biology of Breast Cancer.

Book Synopsis Mammography and Beyond by : National Research Council
Download or read book Mammography and Beyond written by National Research Council and published by National Academies Press. This book was released on 2001-07-23 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year more than 180,000 new cases of breast cancer are diagnosed in women in the U.S. If cancer is detected when small and local, treatment options are less dangerous, intrusive, and costly-and more likely to lead to a cure. Yet those simple facts belie the complexity of developing and disseminating acceptable techniques for breast cancer diagnosis. Even the most exciting new technologies remain clouded with uncertainty. Mammography and Beyond provides a comprehensive and up-to-date perspective on the state of breast cancer screening and diagnosis and recommends steps for developing the most reliable breast cancer detection methods possible. This book reviews the dramatic expansion of breast cancer awareness and screening, examining the capabilities and limitations of current and emerging technologies for breast cancer detection and their effectiveness at actually reducing deaths. The committee discusses issues including national policy toward breast cancer detection, roles of public and private agencies, problems in determining the success of a technique, availability of detection methods to specific populations of women, women's experience during the detection process, cost-benefit analyses, and more. Examining current practices and specifying research and other needs, Mammography and Beyond will be an indispensable resource to policy makers, public health officials, medical practitioners, researchers, women's health advocates, and concerned women and their families.

Download or read book The Breast written by Helmuth Vorherr and published by Elsevier. This book was released on 2012-12-02 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Breast: Morphology, Physiology, and Lactation covers the mammary morphology and function related to endocrine physiology, as well as the pathophysiologic disorders, such as galactorrhea. Knowledge of the many hormones influencing the structure and function of the breast enables one to relate cyclic endocrine ovarian changes to symptoms of premenstrual mammary tension, parenchymal alterations, and breast neoplasia. This book is divided into nine chapters and begins with a description of the female breast development. This topic is followed by a discussion on the morphological aspects of the mature female breast, including the anatomy of the mammary gland, breast changes during pregnancy, and milk synthesis. The next chapters focus on the process of lactation and the hormonal mechanisms involved in lactation maintenance. Other chapters consider the techniques, principles, and advantages of breast feeding, as well as the concept of lactation suppression. The final chapters examine the syndromes, potential causes, and management galactorrhea, which is associated with increased pituitary prolactin secretion and deficient gonadotropin production. This book is of value to medical students, physiologists, endocrinologists, pharmacologists, basic and clinical investigators, physicians, and clinicians.

Available in PDF, EPUB and Kindle. Book excerpt: Improving Institutions for Green Landscapes in Metropolitan Areas investigates how various institutions for green landscapes in metropolitan areas work, which problems hamper them, and how these institutions can be improved. Themes, theories and methods have been selected as a response to the case studies. The following themes were formulated: landscape and institutional developments, the market or government dilemma, the network or hierarchy dilemma, the relation between spatial planning and land development, and Slow Planning and incremental institutional change. Except from the Flemish Park Forest Ghent project, a reflection case, this research examined the Dutch situation and in particular the land consolidation and contemporary developments in Midden-Delfland, the cross-subsidy approach in the Bloemendalerpolder and the National Landscape Laag Holland. The most important methodological recommendation for research in the field of planning, law and economics is to use a multi-theory approach and to select methodology and theory based on the case study data.
Book Synopsis Spheroids in Cancer Research by : H. Acker
Download or read book Spheroids in Cancer Research written by H. Acker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malignant growth of cells is often characterized by disorganization of tissue structure, abnormal blood vessel development, and insuffi cient vascular supply. As a consequence, the cancer cells grow in a three-dimensional pattern in atypical microenvironments which include physical, chemical, and nutritional stresses. Necrosis often develops some distance away from the blood vessels. In association with an inherent instability in malignant cell populations, and also because of the changing micromilieu, significant cellular heteroge neity emerges with regard to various phenotypic characteristics. Both biological behavior and responses to therapeutic agents can be affected. A variety of in vitro and in vivo experimental models exist for research on properties of cancer cells during growth. The multicell spheroid model was developed as a system of intermediate complexity in which three dimensional growth of cells enhances cell-cell interactions and creates micro environments that simulate the conditions in intervascular microregions of tumors or microme tastatic foci. Spheroids may change their cellular characteristics with changing environments during growth. These can be studied under controlled conditions in vitro. Interest in details of experimental methods for this model system stimulated the organization of the First International Conference in Rochester, NY in 1980, the Proceedings of which were summarized in Cancer Research in 1981. Since then there has been a rapid increase in the use of this model system, and increased research on the significance of cell-cell and cell-microenvironment interactions in biology in general.
Book Synopsis Cancer: Cell Structures, Carcinogens and Genomic Instability by : Leon P. Bignold
Download or read book Cancer: Cell Structures, Carcinogens and Genomic Instability written by Leon P. Bignold and published by Springer Science & Business Media. This book was released on 2006 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tumors can be induced by a variety of physical and chemical carcinogens. The resulting tumor cells are usually abnormal in their morphology and behavior and transmit their abnormalities to their daughter tumor cells. Most theories of the pathogenesis of tumors suggest that carcinogens in some way cause alterations either of the genomes or of inheritable patterns of gene expression in normal cells, which then cause morphological and behavioral changes. This volume presents a collection of articles aimed at the question by what genetic or epigenetic mechanisms carcinogens can cause morphological abnormalities of tumor cells. It includes reviews of cellular targets of known carcinogens, and presents varying viewpoints of how morphological abnormalities and the actions of carcinogens might be related. The volume will be of interest to all those who are involved in cancer research or in the prevention, diagnosis or management of tumors in humans or animals.
