Regulation of Angiogenesis by I.D. Goldberg,E.R. Rosen Pdf

We now know that excessive angiogenesis contributes to the development of a variety of disease processes, including cancer, chronic inflammatory disease, and diabetic retinopathy. On the other hand, insufficient angiogenesis may impair wound healing and organ repair. This volume describes recent advances in understanding the molecular regulation of angiogenesis. Subjects covered include important pro-angiogenic growth factors (e.g., vascular endothelial growth factor/vascular permeability factor, scatter factor/hepatocyte growth factor) and their receptors; angiogenesis inhibitors (e.g., thrombospondin-1, angiostatin); extracellular matrix factors (e.g., laminin) and specific vascular integrins (avb3 and avb5) that regulate angiogenesis; the roles of fibrin and the fibrinolytic system in angiogenesis; physical factors that regulate angiogenesis (hypoxia, pH); mechanisms by which specific cell types (macrophages, pericytes) regulate angiogenesis; and lymphangiogenesis, a subject often ignored in volumes of this type. Several chapters are also devoted to the prognostic and therapeutic implications of tumor angiogenesis, a subject of great interest to clinicians. Reflecting the latest advances in this exciting and expanding field, this comprehensive and authoritative monograph will prove invaluable to cell biologists, cancer researchers and pharmacologists.

The regulation of angiogenesis by tissue cell-macrophage interactions by Michal Amit Rahat,Bernhard Hemmerlein,Vijaya Iragavarapu-Charyulu Pdf

Angiogenesis is the physiological process where new blood vessels grow from existing ones, in order to replenish tissues suffering from inadequate blood supply. Perhaps the most studied angiogenic process occurs in solid tumors whose growing mass and expanding cells create a constant demand for additional supply of oxygen and nutrients for survival. However, other physiological and clinical conditions, such as wound healing, ischemic events, autoimmune and age-related diseases also involve angiogenesis. Angiogenesis is a well-structured process that begins when oxygen and nutrients are depleted, leading to the release of chemokines and growth factors that attract immune cells, particularly macrophages and endothelial cells to the site. Macrophages that are recruited to the site, as well as tissue cells and endothelial cells, secrete pro-angiogenic mediators that affect endothelial cells and promote angiogenesis. These mediators include growth factors such as vascular endothelial cell growth factor (VEGF), matrix metalloproteinases (MMPs), as well as low levels of mediators that are usually seen as pro-inflammatory but are pro-angiogenic when secreted in low levels (e.g. nitric oxide (NO) and TNFa). Thus, macrophages play a major role in angiogenesis. Macrophages exhibit high plasticity and are capable of shifting between different activation modes and functions according to their changing microenvironment. Small differences in the composition of activating factors (e.g. TLR ligands such as LPS, anti-inflammatory cytokines, ECM molecules) in the microenvironment may differently activate macrophages to yield classically activated macrophages (or M1 macrophages) that can kill pathogen and tumor cells, alternatively activated macrophages (or M2 macrophages) that secrete antiinflammatory cytokines, resolution macrophages (rM?) that are involved in the resolution of inflammation, or regulatory macrophages (e.g. Myeloid-Derived Suppressor Cells - MDSCs) that control the function of other immune cells. In fact, macrophages may be activated in a spectrum of subsets that may differently contribute to angiogenesis, and in particular non-classically activated macrophages such as tumor-associated macrophages (TAMs) and Tie2-expressing monocytes (TEMs) can secrete high amounts of pro-angiogenic factors (e.g. VEGF, MMPs) or low levels of pro-inflammatory mediators (e.g. NO or TNFa) resulting in pro-angiogenic effects. Although the importance of macrophages as major contributors and regulators of the angiogenic process is well documented, less is known about the interactions between macrophages and other cell types (e.g. tumor cells, normal epithelial cells, endothelial cells) that regulate angiogenesis. We still have only limited understanding which proteins or complexes mediate these interactions and whether they require cell-cell contact (e.g. through integrins) or soluble factors (e.g. the EGF-CSF-1 loop), which signaling pathways are triggered in each of the two corresponding cell types, and how this leads to secretion of pro- or antiangiogenic factors in the microenvironment. The regulation of such interactions and through them of angiogenesis, whether through post-translational modifications of proteins or via the involvement of microRNA, is still unclear. The goal of this Research Topic is to highlight these interactions and their regulation in the context of both physiological and pathological conditions.

Angiogenesis by Thomas H. Adair,Jean-Pierre Montani Pdf

Angiogenesis is the growth of blood vessels from the existing vasculature. The field of angiogenesis has grown enormously in the past 30 years, with only 40 papers published in 1980 and nearly 6000 in 2010. Why has there been this explosive growth in angiogenesis research? Angiogenic therapies provide a potential to conquer cancer, heart diseases, and more than 70 of life's most threatening medical conditions. The lives of at least 1 billion people worldwide could be improved with angiogenic therapy, according to the Angiogenesis Foundation. In this little book, we provide a simple approach to understand the essential elements of the angiogenic process, we critique the most powerful angiogenesis assays that are used to discover proangiogenic and antiangiogenic substances, and we provide an in-depth physiological perspective on how angiogenesis is regulated in normal, healthy tissues of the human body. All tissues of the body require a continuous supply of oxygen to burn metabolic substrates that are needed for energy. Oxygen is conducted to these tissues by blood capillaries: more capillaries can improve tissue oxygenation and thus enhance energy production; fewer capillaries can lead to hypoxia and even anoxia in the tissues. This means that angiogenic therapies designed to control the growth and regression of blood capillaries can be used to improve the survival of poorly perfused tissues that are essential to the body (heart, brain, skeletal muscle, etc.) and to rid the body of unwanted tissues (tumors).

Angiogenesis and Vascularisation by Józef Dulak,Alicja Józkowicz,Agnieszka Łoboda Pdf

The book presents the overview of the current knowledge in some fields of vascular biology, addressing cellular and molecular aspects of blood-vessel formation and their role in health and disease. The major factors involved in the formation of blood vessels are presented by scientists actively involved in this area of research. Special emphasis is put on the presentation of various molecular mechanisms not addressed in similar works to date. The book is divided into three parts. The first part describes the cells and mediators in angiogenesis. The significance of various populations of potential endothelial progenitors is particularly highlighted. The chapters of the second part focus on molecular mechanisms, with special emphasis on the role of hypoxia, gasotransmitters and reactive oxygen species as well as microRNAs in regulation of angiogenic processes. In the third part, the pathological aspects of disturbed – aggravated or impaired – vascularization are discussed and new modalities for potential therapies are presented. The book is intended for scientists and PhD students in the fields of vascular biology and cancer research. It may be of interest for medical professionals in the fields of cardiovascular disease, diabetes, oncology and rheumatoid arthritis.

Inflammation and the Microcirculation by D. Neil Granger,Elena Senchenkova Pdf

The microcirculation is highly responsive to, and a vital participant in, the inflammatory response. All segments of the microvasculature (arterioles, capillaries, and venules) exhibit characteristic phenotypic changes during inflammation that appear to be directed toward enhancing the delivery of inflammatory cells to the injured/infected tissue, isolating the region from healthy tissue and the systemic circulation, and setting the stage for tissue repair and regeneration. The best characterized responses of the microcirculation to inflammation include impaired vasomotor function, reduced capillary perfusion, adhesion of leukocytes and platelets, activation of the coagulation cascade, and enhanced thrombosis, increased vascular permeability, and an increase in the rate of proliferation of blood and lymphatic vessels. A variety of cells that normally circulate in blood (leukocytes, platelets) or reside within the vessel wall (endothelial cells, pericytes) or in the perivascular space (mast cells, macrophages) are activated in response to inflammation. The activation products and chemical mediators released from these cells act through different well-characterized signaling pathways to induce the phenotypic changes in microvessel function that accompany inflammation. Drugs that target a specific microvascular response to inflammation, such as leukocyte-endothelial cell adhesion or angiogenesis, have shown promise in both the preclinical and clinical studies of inflammatory disease. Future research efforts in this area will likely identify new avenues for therapeutic intervention in inflammation.

Angiogenesis: In Vivo Systems by David A. Cheresh Pdf

Angiogenesis is the growth of new blood vessels and is an important natural process in the body. A healthy body maintains a perfect balance of angiogenesis modulators. In many serious disease states, however, the body loses control over angiogenesis. Diseases that are angiogenesis-dependent result when blood vessels either grow excessively or insufficiently. Understanding how angiogenesis "works" and how to control it, will have massive implications on the management, treatments, and ultimately the prevention of many common (and not so common) diseases. Angiogenesis cuts across virtually every discipline. The Angiogenesis Foundation identified angiogenesis as a "common denominator" in our most serious diseases. Excessive angiogenesis occurs in diseases such as cancer, diabetic blindness, age-related macular degeneration, rheumatoid arthritis, psoriasis, and many other conditions. Insufficient angiogenesis occurs in diseases such as coronary artery disease, stroke, and delayed wound healing. * Tried-and-tested techniques written by researchers that developed them, used them, and brought them to fruition. * Provides the "builder's manual" for essential techniques. This is a one-stop shop that eliminates needless searching among untested techniques. * Includes step-by-step methods for understanding the cell and molecular basis of wound healing, vascular integrin signaling, mechanical signaling in blood vessels, and vascular proteomics

New Frontiers in Angiogenesis by Reza Forough Pdf

New Frontiers in Angiogenesis is a fresh and unconventional look at the field of angiogenesis. It focuses on provocative and cutting-edge topics in the field of angiogenesis. Each chapter will take the reader along on a journey into uncharted territories of angiogenesis. The volume starts with a comprehensive overview of the field and continues with topics that have been minimally explored. The topics deal with dynamics of vasculogenesis using imaging techniques, bone marrow-derived endothelial cell precursors as potential therapeutic tools, regulation of post-angiogenic vessel regression, vascular mimicry, design and construction of artificial vessels, bioengineering of angiogenesis, and lymphangiogenesis recapitulating angiogenesis in health and disease states. Each chapter is written by leading experts of the subjects. It is hoped that this volume will challenge all of us interested in the field of angiogenesis and cardiovascular biology, in particular those in academia and industries, to think "outside the box" and explore angiogenesis from a fresh angle. It is hoped that New Frontiers in Angiogenesis is thought provoking and serve as a road map for discovering new findings to help betterments of human health.

Assembly of the Vasculature and Its Regulation by Robert J. Tomanek Pdf

The overall scope of this new series will be to evolve an understanding of the genetic basis of (1) how early mesoderm commits to cells of a heart lineage that progressively and irreversibly assemble into a segmented, primary heart tube that can be remodeled into a four-chambered organ, and (2) how blood vessels are derived and assembled both in the heart and in the body. Our central aim is to establish a four-dimensional, spatiotemporal foundation for the heart and blood vessels that can be genetically dissected for function and mechanism. Since Robert DeHaan's seminal chapter "Morphogenesis of the Vertebrate Heart" published in Organogenesis (Holt Rinehart & Winston, NY) in 1965, there have been surprisingly few books devoted to the subject of cardiovascular mor phogenesis, despite the enormous growth of interest that occurred nationally and internationally. Most writings on the subject have been scholarly compilations of the proceedings of major national or international symposia or multiauthored volumes, often without a specific theme. What is missing are the unifying concepts that can make sense out of a burgeoning database of facts. The Editorial Board of this new series believes the time has come for a book series dedicated to cardio vascular morphogenesis that will serve not only as an important archival and didac tic reference source for those who have recently come into the field but also as a guide to the evolution of afield that is clearly coming of age.

Vascular Development by Derek J. Chadwick,Jamie A. Goode Pdf

The formation of blood vessels is an essential aspect of embryogenesis in vertebrates. It is a central feature of numerous post-embryonic processes, including tissue and organ growth and regeneration. It is also part of the pathology of tumour formation and certain inflammatory conditions. In recent years, comprehension of the molecular genetics of blood vessel formation has progressed enormously and studies in vertebrate model systems, especially the mouse and the zebrafish, have identified a common set of molecules and processes that are conserved throughout vertebrate embryogenesis while, in addition, highlighting aspects that may differ between different animal groups. The discovery in the past decade of the crucial role of new blood vessel formation for the development of cancers has generated great interest in angiogenesis (the formation of new blood vessels from pre-existing ones), with its major implications for potential cancer-control strategies. In addition, there are numerous situations where therapeutic treatments either require or would be assisted by vasculogenesis (the de novo formation of blood vessels). In particular, post-stroke therapies could include treatments that stimulate neovascularization of the affected tissues. The development of such treatments, however, requires thoroughly understanding the developmental properties of endothelial cells and the basic biology of blood vessel formation. While there are many books on angiogenesis, this unique book focuses on exactly this basic biology and explores blood vessel formation in connection with tissue development in a range of animal models. It includes detailed discussions of relevant cell biology, genetics and embryogenesis of blood vessel formation and presents insights into the cross-talk between developing blood vessels and other tissues. With contributions from vascular biologists, cell biologists and developmental biologists, a comprehensive and highly interdisciplinary volume is the outcome.

The Endothelium by Michel Félétou Pdf

The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Angiogenesis in Health, Disease and Malignancy by Ali Salajegheh Pdf

This book is about “Angiogenesis”. A process in which new vasculature is formed from pre-existing capillaries. Angiogenesis process is associated with the proliferation and growth of both physiologically normal and neoplastic tissues, through the formation of vascular supply, essential for delivering growth requirements such as oxygen and nutrients. The book describes more than 100 genes and their key regulatory functions in the context of normal healthy condition, disease and malignancy, cancer proliferation and progression. New insights into the role of angiogenesis and the therapeutic inhibition of its regulators are investigated, due to the great potential for exploitation in the development of a novel treatment for cancer. New scientists, junior researchers and biomedical science students will find this book an invaluable introductory reference to their insight about angiogenesis and angiogenic role of more than 100 angiogenes and their role in healthy, disease and malignant conditions.

Modern Concepts in Angiogenesis by Michael Simons,Gabor M Rubanyi Pdf

This volume addresses current emerging concepts in the field of angiogenesis, including important angiogenesis modifiers which are essential in combination with growth factors (VEGF and FGF) for the physiological process and also for therapeutic applications. It covers many of the lesser discussed areas including blood vessel growth guidance (interactions with CNS) as well as emerging practical applications of these concepts. The book comprises in-depth reviews by leading experts in several major areas: recent basic science discoveries about angiogenesis modifiers (semaphorins, ephrins and nitric oxide, for which the Nobel Prize was awarded); arterial guidance; clinical applications of new angiogenic factors (HGF, HIF and eNOS); and basic and clinical advancement of anti-angiogenic molecules for the treatment of cancer and macular degeneration (tyrosine kinase inhibitors and NO). These topics, especially their unique combination presented in this volume, are not found in any other current books on angiogenesis. This makes the book a must-read for readers both interested and actively involved in the most recent advances in basic principles and clinical applications of angiogenesis.

Mechanisms of Angiogenesis by Matthias Clauss,Georg Breier Pdf

Is it advisable to go back from bedside to the bench? During the last decade, few topics encountered such a broad interest in bio- gy and medicine as angiogenesis. The amazing ability of the body to restore blood flow by induction of blood vessel growth as part of an adaptive process has alarmed physicians dealing with diseases in which angiogenesis is either exaggerated (as in tumors) or too slow (as in ischemic diseases of heart and brain). Not surprisingly, pro- and antiangiogenic strategies have found their way into clinical trials. For instance, for the USA, the NIH website in early 2004 displayed 38 clinical studies involving either pro- or antiangiogenic th- apies. Given the expected overwhelming wealth of clinical data, the question may be asked whether further exploration of biological mechanisms is required or whether results from the bedside are instructive enough to proceed. This question depends also on the progress of pro- and antiangiogenic clinical trials. In the following, I give a short overview about some of the progress that has been made in this field. Since Judah Folkman proposed antiangiogenic tumor therapy thirty years ago, it has become increasingly evident that agents which interfere with blood vessel formation also block tumor progression. Accordingly, antiangiogenic therapy has gained much attention as a potential adjunct to conventional c- cer therapy.
