Available in PDF, EPUB and Kindle. Book excerpt: The “cancer stem cell” hypothesis postulates that cancer arises from a subpopulation of tumor-initiating cells or cancer stem cells (CSCs). While the idea of cancer stem cells has been around for more than a hundred years, evidence from the fields of hematology and cancer biology has now demonstrated the critical role of stem cells in hematological malignancies and suggested that these same mechanisms are also central to the initiation, progression, and treatment of solid cancers. Clinical and experimental studies have shown that CSCs exhibit many classical properties of normal stem cells, including a high self-renewal capacity and the ability to generate heterogeneous lineages; the requirement for a specific “niche”/microenvironment to grow; and an increased capacity for self-protection against harsh environments, toxins, and drugs. Cancer Stem Cells in Solid Tumors represents a detailed overview of cancer stem cells and their role in solid cancers. Comprised of 24 chapters, this volume will provide readers with a comprehensive understanding of this important and evolving field. Topics covered include: Introduction of the CSC hypothesis Historical perspectives and the contributing lessons from leukemia Current knowledge regarding the identification and role of CSCs in various forms of solid cancer including breast, brain, colorectal, pancreatic, prostate, melanoma, lung, ovarian, hepatocellular, and head and neck cancer Molecular pathways involved in driving CSC function, with a particular focus on the novel convergence of embryonic and tumorigenic signaling pathways In vitro and in vivo assays, model systems, and imaging modalities for studying CSCs The clinical importance of CSCs for cancer management and treatment, including important implications for prognosis, prediction, and treatment resistance Consideration of the controversy surrounding the CSC hypothesis and important unanswered questions in this field This collective work was written by a group of prominent international experts in cancer biology, oncology, and/or stem cell biology. It will serve as a valuable resource for established researchers, professors, health care professionals, and students in the medical and scientific community who are investigating stem cells and/or oncology.

This book was released on 2015 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prostate cancer presents a significant paradox: it is very common, yet rarely fatal. To wit, the prostate is the most common non-skin tissue for cancer diagnosis in men in the United States. Despite its high incidence, fatal malignancy occurs in only a small fraction of diagnosed men. The fatal cases are characteristically defined by distant spread in the body, also known as metastasis. In order to metastasize a cancer cell must complete several sequential steps. These include degradation of and invasion through the epithelial basement membrane, typically through the loss of static intracellular adhesions with fellow epithelial cells; entrance into the blood stream (intravasation); survival within circulation; exit from the blood stream upon arrival at a new tissue (extravasation); and survival and colonization at the secondary site. At the time of diagnosis, it is not currently possible to accurately predict future metastasis and thereby clinicians cannot delineate those men at high risk for fatal disease from the vast majority of men who are likely to experience an indolent disease course. Consequently, we examined the behavior of cancer cells in several steps of the metastatic cascade. In doing so, we uncovered both molecular and biophysical characteristics of cancer cells that may facilitate successful metastatic dissemination and tumor outgrowth. Epithelial-to-mesenchymal transition (EMT) is physiological process of transdifferentiation that is normally initiated during vertebrate development, but has recently been implicated in tumor development, progression, and metastases. The EMT program results in dramatic changes, including the exchange of epithelial for mesenchymal markers, altered cellular morphology, and gain of motility. EMT-like cellular alterations have been implicated most strongly in the metastasis steps of invasion and survival of cells at primary tumors sites.

Available in PDF, EPUB and Kindle. Book excerpt: ​​​​Recent evidence demonstrates that normal prostate tissue contains stem cells. There is also accumulating evidence that prostate cancer contains a population of cells with stem cell-like characteristics referred to as cancer stem cells, or tumor initiating cells. Both the normal prostate stem cell and cancer stem cell populations have important implications for the generation, therapeutic targeting, and prevention of prostate cancer. The purpose of this book is to explore the role of stem cells in prostate cancer, which is becoming an increasingly hot trend in cancer research. ​

Download or read book Cancer Stem Cell Resistance to Targeted Therapy written by Cristina Maccalli and published by Springer. This book was released on 2019-06-04 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents an up-dated summary of the state of the art of the characterization of cancer stem cell/ cancer initiating cell (CSC/CIC) properties. An overview of the definition and biological properties of CSCs/CICs as well as the role of these cells in determining the resistance to standard and immune-based therapies is provided. It also discusses limitations in the achievement of a definitive biological characterization of CSCs/CICs due to their high extent of plasticity and heterogeneity that is also mutually driven by the interaction of these cells with the tumor microenvironment. The limitations in targeting CSCs/CICs with immunotherapy are also explained together with explorative combination approaches that could increase the susceptibility of these cells to the recognition by immune cells. This book is conceived for a broad audience, including students, teachers, scientific experts. The critical revision of available results in terms of immunological profile of CSCs/CICs and the efficacy in targeting these cells by immunological approaches, results in a comprehensive and up to date recapitulation of the field and provides interesting suggestions on how to focus future investigations in order to assess the role of CSCs/CICs as prognostic and predictive biomarkers of responsiveness to therapies for cancer patients.

Download or read book Cancer Stem Cell Markers and Related Network Pathways written by Shihori Tanabe and published by Springer Nature. This book was released on 2023-02-02 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book entitled “Cancer Stem Cell Markers and Related Network Path-ways” is about cancer stem cell (CSC) markers and the molecular network pathways. CSCs play an important role in the cancer drug resistance, metastasis and recurrence. Epithelial-mesenchymal transition (EMT) is closely related to CSC phenotype. This book covers various aspects of the molecular networks related to CSCs including the important phenotypic change such as EMT. Readers will discover the importance of the identification of CSC markers and EMT-related molecules in CSC network pathways. The CSC signaling pathways and EMT molecular network pathways attract researchers in the field to define the cancer therapeutic targets. Cancer environment is important in the acquisition of CSC phenotype in cells. The revealing of this CSC mystery is across 7 chapters. The topic of this book is particularly relevant to research in the field of cancer and stem cells, as well as the network pathways. We hope that this book helps the readers to be interested in understanding why the CSC concept is important and attractive.

Available in PDF, EPUB and Kindle. Book excerpt: The recently resurrected cancer stem cell (CSC) theory sheds new light on understanding tumor biology. Most solid tumors have now been shown to contain CSCs, i.e., stem cell-like cancer cells. These cells, although generally rare, appear to be highly tumorigenic and may be the cells that drive tumor formation, maintain tumor homeostasis, and mediate tumor metastasis. In order to test whether any given human tumor cell population has CSC properties, the relatively enriched single tumor cells have to be put into a foreign microenvironment in a recipient animal to test their tumorigenic potential. Furthermore, various in vitro assays can be performed to demonstrate that the presumed CSCs have certain biological properties normally associated with the stem cells (SCs). Herein, I first present a comprehensive review of the experimental methodologies that our lab has been using in assaying putative prostate cancer (PCa) SCs in culture, xenograft tumors, and primary tumor samples. Clonal morphology is one of the critical properties of cultured cancer cells that has been largely ignored. Interestingly, long term-cultured human epithelial cancer cells form holoclones, meroclones, and paraclones, and tumor cell holoclones have been hypothesized to harbor stem-like cells. Using PC3 human prostate carcinoma cells as a model, we provide direct experimental evidence that tumor cell holoclones contain stem-like cells that can initiate serially transplantable tumors. Importantly, holoclones derived from either cultured PC3 cells or holoclone-initiated tumors can be serially passaged and regenerate all three types of clones. In contrast, meroclones and paraclones cannot be continuously propagated and fail to initiate tumor development. Phenotypic characterizations reveal high levels of CD44, [alpha]2[beta]1 integrin, and [beta]-catenin expression in holoclones, whereas meroclones and paraclones show markedly reduced expression of these markers. These observations have important implications in understanding morphologic heterogeneities and tumorigenic hierarchies in human epithelial cancer cells. PCa metastasis represents the worst outcome, and, if unchecked, will eventually kill the patient. Although many PCa cell-intrinsic molecules and end-organ factors have been implicated in the metastatic dissemination of PCa cells, the role of primary tumor microenvironment and the nature of the metastatic PCa cells remain poorly defined. By establishing a reliable and quantifiable experimental PCa metastasis model in NOD/SCID mice, we show that PCa cells implanted orthotopically (i.e., in the prostate) metastasize much more extensively and widely than those implanted ectopically (i.e., subcutaneously or s.c). Microarray-based gene expression profiling reveals that the orthotopically implanted human PCa cells prominently overexpress not only several classes of molecules involved in proteolysis/invasion/angiogenesis and inflammation, but also numerous developmental and SC regulating genes. These latter observations suggest that the orthotopic microenvironment (i.e. mouse prostate) appears to be promoting the manifestation of CSC phenotypes and these CSCs might be involved in enhanced metastasis in the orthotopic microenvironment and later distant organ metastasis. In support, shRNA-mediated knockdown in many metastatic and CSC genes greatly inhibits PCa cell metastasis. Importantly, PCa cells that express high levels of osteopontin (OPN) or CD24, when prospectively purified out and used in spontaneous metastasis assays, demonstrate high metastatic capacities characteristic of metastatic CSCs. In sharp contrast, PCa cells negative for OPN and CD24 expression show little metastatic property. Finally, we provide multiple pieces of additional evidence that metastatic/metastasizing PCa cells possess CSC properties.

Available in PDF, EPUB and Kindle. Book excerpt: Significance of Stem Cells to Tumor Development Cancer stem cells remain a controversial topic and the criteria that define cancer stem cells are continuing to evolve. A recent surge in stem cell research has ignited a field of discovery into many human diseases including diabetes, neuropathologies, and cancer. By replacing specific differentiated cells that have either been lost or died, stem cell therapy proves to be a very promising approach to the treatment of many debilitating diseases. Though stem cells may provide therapeutic benefit under certain conditions, they are also often implicated in the initiation, progression, and therapeutic resistance of malignant disease. This first edition of Stem Cells and Cancer is intended to give a current perspective on the role of stem cells in cancer and strategies for novel therapies directed toward tumor stem cells. The current cancer stem cell hypothesis is presented in several chapters with distinctions made between the hierarchical and stochastic models of tumor cell development. "Stemness," self-renewal, pluripotency, clonality, and tumorigenicity are important concepts applied towards defining cancer stem cells. Signaling pathways such as Wnt, Sonic Hedgehog, Notch, and Bmi-1 that are involved in differentiation, proliferation, and survival are implicated in the malignant process. Additional chapters address the identification of cancer stem cell populations through the evaluation of molecular markers such as CD133, CD44, and CD24, for example, or by Hoescht dye exclusion to recognize ‘side populations.’ Mesenchymal and hematopoietic stem cells are described as well as mouse models that are employed to elucidate the properties and functionality of stem cells in cancer and the stem cell niche. This book encompasses a wide variety of human cancers that include but are not limited to leukemia, gliomas, breast, and prostate cancers. Resistance to conventional therapies, genetic versus epigenetic changes that affect therapeutic response and strategies to prevent disease recurrence are challenges have been incorporated into this volume. Stem Cells and Cancer represents a compendium of cutting edge research by experts in the field and will be instrumental in the study of this intriguing line of investigation for many years to come.

Download or read book Cancer Metastasis and Cancer Stem Cell Niche written by Takanori Kawaguchi and published by Bentham Science Publishers. This book was released on 2016-11-04 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: A malignant tumor is an actively growing tissue, composed of cells derived from a single cell line that has undergone irreversible differentiation. These cells are invasive and also metastasize in the body, resulting in malignant cancer. Recent research suggests that a malignant tumor originates from cancer stem cells (CSC) accompanied with physiological niches. Cancer Metastasis and Stem Cell/Niche explains the invasiveness and metastasis of cancer cells I the light of information gained from the CSC / niche theory. Five chapters present a review on the fundamental relationships between CSCs, their niche and metastasis, the regulation of cell surface glycan expression in CSCs, tumor endothelial cells and metastasis, toll-like receptor 4 (TLR4)-mediated premetastatic microenvironment, and in surgical cancer metastasis. This monograph is intended as a primary reference on CSC research for physiologists, clinical oncologists, stem cell researchers and molecular biologists.

This book was released on 2012-11-19 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​​​​​​​Prominin-1 or otherwise known as CD133 is a glycoprotein that is present in humans and mice. Since the first description of prominin in 1997, in mouse neuroepithelial cells and in human hematopoietic stem cells as AC133 antigen, this molecule has aroused a large interest especially, as a stem cell marker, that gave rise to an ever growing body of publications and more recently its expression in cancer stem cells. Controversies as to its role as a cancer stem and its detection in different models, as well as its use as a prognostic marker have emerged. Yet, beyond its use as a stem cell and cancer stem cell marker, prominin-1/CD133 displays unique biological features and appears of importance in other processes like for example in retinal biogenesis. Indeed, this five-transmembrane plasma membrane glycoprotein, which marks membrane protrusions is associated with several essential processes like cell polarity, asymmetric cell division and membrane remodeling. We propose to review current knowledge about this intriguing molecule and present pertinent information to determine the biological role of prominins and assess their importance in medicine and cancer research. The primary audience for this book is geared towards scientists and researchers with interest in cancer stem cells, stem cells, cell biology, neurobiology, and regenerative medicine.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
