Book Description
The mammary gland relies on stromal-epithelial interactions for proper development. Tumorigenesis occurs when these signals are misinterpreted. Here we show that stromal matrix metalloproteinases (MMPs) have distinct roles in mammary gland branching morphogenesis. MMP activity is required for normal mammary gland development since mice treated with a synthetic MMP inhibitor, GM6OOl, have retarded ductal development. Furthermore, 3D cultures of mammary organoids also require MMP activity to branch in response to growth factors, indicating a mammary specific response. We also show that specific MMPs are required for distinct aspects of mammary gland morphogenesis. Specifically, MMF-3 is needed for branching because MMP-3 null mice have significantly fewer branches than controls. However, the ductal length is normal. In contrast, MMP-2 is required for ductal elongation, since the ducts of MMP-2 null mice are retarded in their penetration into the fat pad. However, the branching of the MMP-2 null ducts is normal. MMP-l4 is a known activator of MMP-2 and we show it is highly expressed in front of terminal end buds. Mammary glands deficient in MMP-l4 grown under the kidney capsule of nude mice also have defective ductal morphogenesis. Thus, these stromal enzymes are important, and have distinct roles, in patterning the mammary gland.

Book Description
Regulated turnover of extracellular matrix (ECM) is an important component of tissue homeostasis. In recent years, the enzymes that participate in, and control ECM turnover have been the focus of research that touches on development, tissue remodeling, inflammation and disease. This volume in the Biology of Extracellular Matrix series provides a review of the known classes of proteases that degrade ECM both outside and inside the cell. The specific EMC proteases that are discussed include cathepsins, bacterial collagenases, matrix metalloproteinases, meprins, serine proteases, and elastases. The volume also discusses the domains responsible for specific biochemical characteristics of the proteases and the physical interactions that occur when the protease interacts with substrate. The topics covered in this volume provide an important context for understanding the role that matrix-degrading proteases play in normal tissue remodeling and in diseases such as cancer and lung disease.

Book Description
Tissue Repair, Contraction and the Myofibroblast summarizes the latest findings concerning the biology of the myofibroblast, a cell involved in the evolution and contraction of granulation tissue and of fibrotic changes. Coverage shows that the myofibroblast is responsible for the development of hypertrophic scars, pulmonary and renal fibrosis and bronchial asthma. Reviews the cell biology and pathology of the myofibroblast as well as mechanisms of fibrosis evolution in many organs and tissues.

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
Genetic alterations in cancer, in addition to being the fundamental drivers of tumorigenesis, can give rise to a variety of metabolic adaptations that allow cancer cells to survive and proliferate in diverse tumor microenvironments. This metabolic flexibility is different from normal cellular metabolic processes and leads to heterogeneity in cancer metabolism within the same cancer type or even within the same tumor. In this book, we delve into the complexity and diversity of cancer metabolism, and highlight how understanding the heterogeneity of cancer metabolism is fundamental to the development of effective metabolism-based therapeutic strategies. Deciphering how cancer cells utilize various nutrient resources will enable clinicians and researchers to pair specific chemotherapeutic agents with patients who are most likely to respond with positive outcomes, allowing for more cost-effective and personalized cancer therapeutic strategies.

Book Description
Extracellular matrix proteins are serious, common human diseases that are caused by mutations in genes that encode these proteins. This has spurred a great number of researchers to study the extracellular matrix, sometimes by choice and sometimes by necessity. Much progress has been made in the last decade towards understanding what matrix proteins do and how cells interact with and respond to them. Volume 15 is a compilation of reviews by experts in their respective fields. The chapters in this book address the biology of a broad spectrum of extracellular matrix molecules and their functions in development and disease. This book has been designed to focus on a diverse subset of matrix proteins that have been shown to be important for development, function, and disease. The book therefore both presents a broad view of the field and provides crucial details about some of the best-studied matrix molecules. * Written by leaders in the field * Discusses the potential of matrix components to be used as therapeutic tools for the treatment and prevention of cancer * Offers a section on integrin signaling and the development of the central nervous system, detailing the migration of neurons and the glia * Covers a diverse array of molecules such as laminins, collagens, heparan sulfate proteoglycans, integrins, and more
