Download or read book Hypoxia and Cancer written by Giovanni Melillo and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: The imbalance between rapidly proliferating tumor cells and inadequate and inefficient tumor vasculature leads to a decrease in oxygen levels (hypoxia and/or anoxia) in tumor tissues. Intra-tumor hypoxia profoundly affects the biological behavior of cancer cells, which become resistant to conventional therapies and acquire a more invasive and metastatic phenotype. Hypoxia is a hallmark of the malignant phenotype and a key feature of the tumor microenvironment. Hypoxia Inducible Factor 1 (HIF-1) is a master regulator of the transcriptional response to oxygen deprivation. HIF triggers the expression of genes whose products induce angiogenesis, decrease oxygen consumption, switch metabolism to glycolysis, maintain a stem cell phenotype and select for more invasive and metastatic cells. Therapeutic approaches targeting HIF, directly or downstream mediators of its transcriptional activity, are being developed. Intra-tumor hypoxia is a topic has been gaining scientific interest over the last few years for its wide involvement in many physiological and pathological processes. This volume will cover the latest research and translational aspects associated with intra-tumor hypoxia, along with opportunities for drug development offered by this unique feature of the tumor microenvironment. The ongoing efforts to translate our understanding of the biology underlying intra-tumor hypoxia in viable therapeutic options face many challenges, but this book will provide an opportunity for an in-depth analysis of the fundamental mechanisms implicated in the adaption to low oxygen levels and will scrutinize the potential for opportunities that are being pursued in both research and the drug development industry.
Download or read book Hypoxia and Cancer Metastasis written by Daniele M. Gilkes and published by Springer. This book was released on 2019-06-14 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book is an attempt to provide a detailed review of studies that clarify our current understanding of the role of hypoxia in the progression of primary cancer to metastatic disease. It will enable researchers to discover the critical cellular changes that occur under hypoxic conditions and play a role in metastatic dissemination, from the activation of hypoxia-inducible factors, HIF-1 and HIF-2, to the transcriptional profile changes that occur in cancer cells and promote cancer cell survival under detrimental conditions. Readers will discover the methods and challenges involved in imaging and quantifying the degree of hypoxia in a primary tumor. We will provide an understanding of the hypoxia-induced phenotypes that influence heterogeneity, alter the secretome and tumor microenvironment, modify cellular metabolism, and promote immune suppression and resistance to chemotherapy. Finally, we will uncover the therapeutic strategies that are being devised to target the hypoxic microenvironment in the hopes of preventing metastasis and improving the efficacy of standard-of-care cancer treatments. This work is an up to date source of information on the challenges and complexity of the hypoxic tumor microenvironment. Basic and translational scientists, post-doctoral fellows, graduate students, and those interested in how tumors metastasize will find this book a reference that details how hypoxia influences metastatic disease.

This book was released on 2017-01-31 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hypoxic regions have been identified within tumors and its presence has been linked to malignant progression, metastasis, resistance to therapy, and poor clinical outcomes following treatment. Acute and chronic hypoxia are integral components of tumor microenvironment and conduce to metabolic adaptations of tumor cells leading to genetic instability, intratumor heterogeneity and malignant progression. On the success of our fight against cancer, the continued adaptability of tumors to their microenvironmental stresses, such as hypoxia, must be considered. Tumor cells are endowed with a very high plasticity and capacity to adapt. It is our challenge to find populations and conditions of the tumor microenvironment germane for target success. Interdisciplinary work will be the key for achievement of these goals. This e-book is a compendium of original reports and review articles contributed by world-class experts in the field of tumor hypoxia. This material will be useful to foster discussion and increase understanding of the involvement of hypoxia in tumorigenesis, biomarker development, and therapeutics.

Download or read book Diverse Effects of Hypoxia on Tumor Progression written by M. Celeste Simon and published by Springer Science & Business Media. This book was released on 2010-09-28 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hypoxia, defined as reduced oxygen tension, is a common physiological phenomenon in both normal embryonic development and malignancy progression. Although severe hypoxia is generally toxic for both normal tissue and tumors, neoplastic cells gradually adapt to prolonged hypoxia though additional genetic and genomic changes with a net result that hypoxia promotes tumor progression and therapeutic resistance. Hypoxia promotes cancer progression by regulating various aspects of cancer biology, including radiotherapy resistance, metabolism, angiogenesis and invasion/migration
Download or read book The Heterogeneity of Cancer Metabolism written by Anne Le and published by Springer. This book was released on 2018-06-26 with total page 186 pages. 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.

Download or read book The Mechanistic and Therapeutic Implications of Tumor Hypoxia in the TRAIL Signaling Pathway written by Patrick A. Mayes and published by . This book was released on 2015 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: As tumors grow, oxygen supplied by local blood vessels fails to reach remote tumor cells. Cancer cells respond to limiting oxygen by stimulating the formation of their own vascular supply. However, blood vessels formed by tumors are often abnormal and nonfunctional. The result is that the majority of solid tumors contain regions with low or inconsistent oxygen availability - termed tumor hypoxia. Hypoxic stress provides a selective pressure for the enrichment of tumor cells with a more aggressive and metastatic phenotype as well as a loss of apoptotic potential; which poses a significant barrier to treatment of solid tumors. Hypoxic tumor cells are largely resistant to traditional ionizing radiation and chemotherapies via well defined resistance mechanisms involving activation of multidrug resistant pumps, decreased proliferation and the lack of O 2 -dependent fixation of therapy-induced DNA damage. We were interested in how tumor hypoxia may affect sensitivity of cancer cells to treatment with therapies targeting the tumor-necrosis factor related apoptosis inducing ligand (TRAIL) family of membrane bound death receptors. We found that hypoxia has a significant effect on the relative sensitivity of human cancer cells treated with TRAIL by altering the expression of mediators of the apoptotic signaling pathway. We went on to identify a mechanism by which hypoxia activates TRAIL signaling in cancer cells with wild-type p53, through p53-mediated repression of the anti-apoptotic protein c-FLIP. In addition, we identified mechanisms by which hypoxia promotes TRAIL resistance in cancer cells lacking wild-type p53. Attempts to reverse hypoxia-induced apoptotic resistance by combining TRAIL with chemotherapy or Tirapazamine (TPZ) failed to significantly affect TRAIL resistance in hypoxic cells. Therefore, we screened a library of small molecules against hypoxia-induced TRAIL-resistant cells which identified a class of structurally related compounds (SLMs) which re-sensitize hypoxic cells to TRAIL-induced apoptosis. Further studies were carried out with in vivo mouse models using real-time optical imaging to analyze the consequence of tumor hypoxia on TRAIL efficacy with or without the addition of SLMs. By performing real-time imaging of tumor vasculature we discovered that one of the consequences of hypoxic tumor cell resistance was increased angiogenesis. However, by combining SLMs with TRAIL tumor angiogenesis was inhibited. These findings demonstrate that tumor hypoxia can significantly alter apoptotic signaling as well as the efficacy of TRAIL targeted therapies. Our results suggest that hypoxia-targeted adjuvants may be required to optimize therapeutic regiments which include TRAIL in some human tumors, specifically those lacking p53.
Download or read book Cancer as a Metabolic Disease written by Thomas Seyfried and published by John Wiley & Sons. This book was released on 2012-05-18 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book addresses controversies related to the origins of cancer and provides solutions to cancer management and prevention. It expands upon Otto Warburg's well-known theory that all cancer is a disease of energy metabolism. However, Warburg did not link his theory to the "hallmarks of cancer" and thus his theory was discredited. This book aims to provide evidence, through case studies, that cancer is primarily a metabolic disease requring metabolic solutions for its management and prevention. Support for this position is derived from critical assessment of current cancer theories. Brain cancer case studies are presented as a proof of principle for metabolic solutions to disease management, but similarities are drawn to other types of cancer, including breast and colon, due to the same cellular mutations that they demonstrate.
