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 Tumor Microenvironment written by Jacinta Serpa and published by Springer Nature. This book was released on 2020-03-04 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: The way a cell undergoes malignant transformation should meet their capacity of surviving in the microenvironment of the organ where the cancer will develop. Metabolic adaptation is for sure one of the criteria that must be accomplished, driven by metabolic plasticity that allows the adaptation of cancer cells to the availability of energy and biomass sources that will sustain cell survival and proliferation. Each human organ has a particular microenvironment which depends on several cell types and in some cases also on symbiotic microorganisms. These biological partners are constantly sharing organic compounds and signaling molecules that will control mitogenesis, cell death and differentiation, accounting for the organ's function. Nevertheless, cancer cells are capable of taking advantage of this metabolic and signaling microenvironmental dynamics. In this book, we intend to present the different components of the microenvironment driving the metabolic fitness of cancer cells. The metabolic changes required for establishing a tumor in a given microenvironment and how these metabolic changes limit the response to drugs will generally be the major items addressed. It is important to mention not only aspects of the microenvironment that stimulate metabolic changes and that select better adapted tumor cells, but also how this regulation of cell plasticity is made. Thus, the signaling pathways that orchestrate and are orchestrated throughout this panoply of metabolic rearrangements will also be addressed in this book. The subjects will be presented from the conceptual point of view of the cross-cancer mechanisms and also particularizing some models that can be examples and enlightening within the different areas.

Download or read book Redox and Metabolic Circuits in Cancer written by Salvatore Rizza and published by Frontiers Media SA. This book was released on 2018-12-21 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living cells require a constant supply of energy for the orchestration of a variety of biological processes in fluctuating environmental conditions. In heterotrophic organisms, energy mainly derives from the oxidation of carbohydrates and lipids, whose chemical bonds breakdown allows electrons to generate ATP and to provide reducing equivalents needed to restore the antioxidant systems and prevent from damage induced by reactive oxygen and nitric oxide (NO)-derived species (ROS and RNS). Studies of the last two decades have highlighted that cancer cells reprogram the metabolic circuitries in order to sustain their high growth rate, invade other tissues, and escape death. Therefore, this broad metabolic reorganization is mandatory for neoplastic growth, allowing the generation of adequate amounts of ATP and metabolites, as well as the optimization of redox homeostasis in the changeable environmental conditions of the tumor mass. Among these, ROS, as well as NO and RNS, which are produced at high extent in the tumor microenvironment or intracellularly, have been demonstrated acting as positive modulators of cell growth and frequently associated with malignant phenotype. Metabolic changes are also emerging as primary drivers of neoplastic onset and growth, and alterations of mitochondrial metabolism and homeostasis are emerging as pivotal in driving tumorigenesis. Targeting the metabolic rewiring, as well as affecting the balance between production and scavenging of ROS and NO-derived species, which underpin cancer growth, opens the possibility of finding selective and effective anti-neoplastic approaches, and new compounds affecting metabolic and/or redox adaptation of cancer cells are emerging as promising chemotherapeutic tools. In this Research Topic we have elaborated on all these aspects and provided our contribution to this increasingly growing field of research with new results, opinions and general overviews about the extraordinary plasticity of cancer cells to change metabolism and redox homeostasis in order to overcome the adverse conditions and sustain their “individualistic” behavior under a teleonomic viewpoint.
Download or read book Cancer Stem Cells in Solid Tumors written by Alison L. Allan and published by Springer Science & Business Media. This book was released on 2011-08-12 with total page 479 pages. 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.
Download or read book Tumor Microenvironment written by Jacinta Serpa and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will allow readers to discover the crucial role of tumor microenvironment (TME) in the selection of cancer cells that are more prone to carry on cancer initiation and progression. The metabolic remodeling, as the basis of life overall, allows the adaptive establishment of a tumor in a certain TME, which in turn presents a variety of selective pressures. Coupled with the late diagnosis, the poor therapy response are the main hurdles limiting oncological disease control and eventual cure. Thus the metabolic plasticity of cancer cells often underlies chemoresistance. This edited work presents an exhaustive description and comprehensive view of cancer metabolism as a weapon used by cancer cells to adapt to TME. TME and the organ microenvironment is analyzed as a whole, considering cancer cells, stromal cells and microbiota. This complex circuit is observed as the support for disease development and therapy evasion but also as a valuable kernel, presenting new players to be targeted in a more precise cancer therapy. The various threads of cancer biology related to TME and metabolic adaptation will be addressed including: 1) key players in the metabolic network; 2) the way adaptive metabolic features are sustained by TME; 3) TME and metabolic signaling, accounting for cancer cells survival; 4) metabolic fitness driven limitations in therapy response, and 5) the way TME and cancer metabolism can be helpful in the design of new drugs. In addition, the usefulness, technical strengths and weaknesses of analytical techniques useful in cancer metabolomics will be presented in an integrative way. Moreover, the use of innovative and traditional in vitro and in vivo cancer models, as powerful tools to address the influence of TME in cancer progression and metabolic reprogramming will be also presented. This work was written by experts and dedicated to researchers with interests in cancer biology, TME, cancer metabolism and therapy. It will interest the Advances in Experimental Medicine and Biology readership, including basic researchers, analytic researchers, bio-engineers and clinicians.
Download or read book Metabolism in Cancer written by Thorsten Cramer and published by Springer. This book was released on 2016-08-24 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook presents concise chapters written by internationally respected experts on various important aspects of cancer-associated metabolism, offering a comprehensive overview of the central features of this exciting research field. The discovery that tumor cells display characteristic alterations of metabolic pathways has significantly changed our understanding of cancer: while the first description of tumor-specific changes in cellular energetics was published more than 90 years ago, the causal significance of this observation for the pathogenesis of cancer was only discovered in the post-genome era. The first 10 years of the twenty-first century were characterized by rapid advances in our grasp of the functional role of cancer-specific metabolism as well as the underlying molecular pathways. Various unanticipated interrelations between metabolic alterations and cancer-driving pathways were identified and currently await translation into diagnostic and therapeutic applications. Yet the speed, quantity, and complexity of these new discoveries make it difficult for researchers to keep up to date with the latest developments, an issue this book helps to remedy.

Download or read book Cellular and Phenotypic Plasticity in Cancer written by Petranel Theresa Ferrao and published by Frontiers Media SA. This book was released on 2015-09-17 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process of Epithelial-Mesenchymal-Transition (EMT) is known to result in a phenotype change in cells from a proliferative state to a more invasive state. EMT has been reported to drive the metastatic spread of various cancers and has also been associated with drug resistance to cytotoxics and targeted therapeutics. Recently phenotype switching akin to EMT has been reported in non-epithelial cancers such as metastatic melanoma. This process involves changes in EMT-Transcription Factors (EMT-TFs), suggesting that phenotype-switching may be common to several tumour types. It remains unclear as to whether the presence of both Epilthelial-like and Mesenchymal-like cells are a pre-requisite for phenotype switching within a tumour, how this heterogeneity is regulated, and if alteration of cell phenotype is sufficient to mediate migratory changes, or whether drivers of cell migration result in an associated phenotype switch in cancer cells. Similarly it has yet to be clarified if cells in an altered phenotype can be refractory to drug therapy or whether mediators of drug resistance induce a concurrent phenotypic change. Little is known today about the underlying genetic, epigenetic and transient changes that accompany this phenotypic switch and about the role for the tumor micro-environment in influencing it. Hence this is currently an area of speculation and keen interest in the Oncology field with wide-ranging translational implications. In this Frontiers Research Topic, we discuss our current understanding of these concepts in various cancer types including breast cancer, colorectal cancer and metastatic melanoma. This topic covers how these processes of cellular and phenotypic plasticity are regulated and how they relate to cancer initiation, progression, dormancy, metastases and response to cytotoxics or targeted therapies.

Download or read book Cancer Metabolism Molecular Targeting and Implications for Therapy written by Shanmugasundaram Ganapathy-Kanniappan and published by Frontiers Media SA. This book was released on 2017-11-03 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of an effective anticancer therapeutic necessitates the selection of cancer-related or cancer-specific pathways or molecules that are sensitive to intervention. Several such critical yet sensitive molecular targets have been recognized, and their specific antagonists or inhibitors validated as potential therapeutics in preclinical models. Yet, majority of anticancer principles or therapeutics show limited success in the clinical translation. Thus, the need for the development of an effective therapeutic strategy persists.
“Altered energy metabolism” in cancer is one of the earliest known biochemical phenotypes which dates back to the early 20th century. The German scientist, Otto Warburg and his team (Warburg, Wind, Negelein 1926; Warburg, Wind, Negelein 1927) provided the first evidence that the glucose metabolism of cancer cells diverge from normal cells. This phenomenal discovery on deregulated glucose metabolism or cellular bioenergetics is frequently witnessed in majority of solid malignancies. Currently, the altered glucose metabolism is used in the clinical diagnosis of cancer through positron emission tomography (PET) imaging. Thus, the “deregulated bioenergetics” is a clinically relevant metabolic signature of cancer cells, hence recognized as one of the hallmarks of cancer (Hanahan and Weinberg 2011). Accumulating data unequivocally demonstrate that, besides cellular bioenergetics, cancer metabolism facilitates several cancer-related processes including metastasis, therapeutic resistance and so on. Recent reports also demonstrate the oncogenic regulation of glucose metabolism (e.g. glycolysis) indicating a functional link between neoplastic growth and cancer metabolism. Thus, cancer metabolism, which is already exploited in cancer diagnosis, remains an attractive target for therapeutic intervention as well. The Frontiers in Oncology Research Topic “Cancer Metabolism: Molecular Targeting and Implications for Therapy” emphases on recent advances in our understanding of metabolic reprogramming in cancer, and the recognition of key molecules for therapeutic targeting. Besides, the topic also deliberates the implications of metabolic targeting beyond the energy metabolism of cancer. The research topic integrates a series of reviews, mini-reviews and original research articles to share current perspectives on cancer metabolism, and to stimulate an open forum to discuss potential challenges and future directions of research necessary to develop effective anticancer strategies. Acknowledgment I sincerely thank the Frontiers for providing the opportunity and constant support throughout the process of this research topic and eBook production.

Download or read book Autophagy in tumor and tumor microenvironment written by Sujit Kumar Bhutia and published by Springer Nature. This book was released on 2020-10-24 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the paradoxical role of autophagy in tumor suppression and tumor promotion in cancer cells. Autophagy plays opposing, context-dependent roles in tumors; accordingly, strategies based on inhibiting or stimulating autophagy could offer as potential cancer therapies. The book elucidates the physiological role of autophagy in modulating cancer metastasis, which is the primary cause of cancer-associated mortality. Further, it reviews its role in the differentiation, development, and activation of multiple immune cells, and its potential applications in tumor immunotherapy. In addition, it examines the effect of epigenetic modifications of autophagy-associated genes in regulating tumor growth and therapeutic response and summarizes autophagy’s role in the development of resistance to a variety of anti-cancer drugs in cancer cells. In closing, it assesses autophagy as a potential therapeutic target for cancer treatment. Given its scope, the book offers a valuable asset for all oncologists and researchers who wish to understand the potential role of autophagy in tumor biology.

Download or read book Keto for Cancer written by Miriam Kalamian and published by Chelsea Green Publishing. This book was released on 2017 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Comprehensive Guide for Patients and Practitioners Although evidence supporting the benefits of ketogenic diet therapies continues to mount, there is little to guide those who wish to adopt this diet as a metabolic therapy for cancer. Keto for Cancer fills this need. Inspired by the work of Dr. Thomas N. Seyfried, PhD, nutritionist Miriam Kalamian has written the first book to lay out comprehensive guidelines that specifically address the many challenges associated with cancer, and particularly the deep nutritional overhaul involved with the ketogenic diet. Kalamian, a leading voice in the keto movement, is driven by passion from her own experience in using the ketogenic diet for her young son. Her book addresses the nuts and bolts of adopting the diet, from deciding whether keto is the right choice to developing a personal plan for smoothly navigating the keto lifestyle. It is invaluable for both beginners and seasoned users of the ketogenic diet, as well as for health-care professionals who need a toolkit to implement this targeted metabolic therapy. The book guides readers to a deeper understanding of the therapeutic potential of the ketogenic diet--which extends well beyond simply starving cancer--emphasizing the powerful impact the diet has on the metabolism of cancer cells. Nutritional nuances are explored in sections such as "Fasting Protocols" and "Know What's in the Foods You Eat" while meal templates and tracking tools are provided in "Preparing Keto Meals." Kalamian also discusses important issues such as self-advocacy. Readers of Keto for Cancer are empowered to "get off the bench and get in the game." To that end, Kalamian offers tips on how to critically examine cancer-care options then incorporate what resonates into a truly personalized treatment plan.
Download or read book Epithelial Mesenchymal Plasticity in Cancer Metastasis written by Mohit Kumar Jolly and published by MDPI. This book was released on 2020-12-29 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have highlighted that epithelial-mesenchymal transition (EMT) is not only about cell migration and invasion, but it can also govern many other important elements such as immunosuppression, metabolic reprogramming, senescence-associated secretory phenotype (SASP), stem cell properties, therapy resistance, and tumor microenvironment interactions. With the on-going debate about the requirement of EMT for cancer metastasis, an emerging focus on intermediate states of EMT and its reverse process mesenchymal-epithelial transition (MET) offer new ideas for metastatic requirements and the dynamics of EMT/MET during the entire metastatic cascade. Therefore, we would like to initiate discussions on viewing EMT and its downstream signaling networks as a fulcrum of cellular plasticity, and a facilitator of the adaptive responses of cancer cells to distant organ microenvironments and various therapeutic assaults. We hereby invite scientists who have prominently contributed to this field, and whose valuable insights have led to the appreciation of epithelial-mesenchymal plasticity as a more comprehensive mediator of the adaptive response of cancer cells, with huge implications in metastasis, drug resistance, tumor relapse, and patient survival.
