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 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.

Available in PDF, EPUB and Kindle. Book excerpt: New Strategies Targeting Cancer Metabolism: Anticancer Drugs, Synthetic Analogues and Antitumor Agents presents up-to-date synthetic strategies for three categories of antimetabolites: antifolates, purines and pyrimidines, the main classes of antimetabolites which are integrated into various pharmaceutical agents. Many of these antimetabolites are considered potent chemotherapeutic agents which have great potential impact on medical research. These main classes of antimetabolites are used in the treatment of critical diseases including cancer, malignancies, autoimmune diseases, and many other non-malignant diseases. Antineoplastic drugs such as alkylating agents which have significant effects are described. Novel synthetic strategies for many anticancer alkylating agents including nitrogen mustards, chlorambucil, melphalan, ifosamide, oxaliplatin and temozolomide are explored. Natural products have offered some of the most significant drugs for treating cancer, as many drugs currently in clinical use are derived from natural products as camptothecins, vinca alkaloids, and derivatives of podophyllotoxin. They provide a contribution that is essential for modern drug discovery and development. In this book, insights into a broad array of novel compounds are reviewed, well-recognized synthetic approaches are emphasized for further anticancer drug development and discovery, and the biological evaluation of novel synthesized compounds are included.

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.

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. I gratefully acknowledge all the authors for their valuable contributions. Finally, I would like to thank my brother, Saravana Kumar, G.K., whose personal sacrifices and unflinching encouragement made my career in science possible. References: Hanahan D, Weinberg RA. 2011.

Download or read book Reviews on New Drug Targets in Age Related Disorders written by Paul C. Guest and published by Springer Nature. This book was released on 2021-03-16 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging is an inevitable part of life, and is becoming a worldwide social, economic and health problem due to the fact that an increasing proportion of individuals in the advanced age category have a higher probability of developing age-related disorders. New therapeutic approaches are still in need to decrease or slow the effects of such diseases in this aging society. Advances in ‘omic technologies such as genomics, transcriptomics, proteomics and metabolomics have significantly advanced our understanding of diseases in multiple medical areas. It is hoped that emerging hits from these analyses might be prioritized for further screening as potential novel drug targets for increasing the human healthspan in line with the lifespan, which will in turn lead to new therapeutic strategies and drug development projects by the pharmaceutical industry. This new book presents a series of reviews describing studies which have resulted in the identification of potential new drug targets for age-related disorders. Much of this information has come from ‘omic comparisons of healthy and disease states or from testing the effects of potential new therapeutic approaches. Each chapter will be presented in the context of specific chronic diseases or different therapeutic strategies, providing important information on disease mechanisms related to the aging process. This book will be of interest to researchers in the areas of aging and chronic disease, as well as clinical scientists, physicians, and major drug companies. With contributors from Australia, Brazil, Canada, France, Germany, India, Iran, Iraq, South Africa, South Korea, Thailand, Ukraine, United Kingdom, United States of America, Uruguay and Vietnam, this is a timely follow up to Guest’s previous book Reviews on New Drug Targets in Age-Related Disorders.

Download or read book Targeting Cancer Metabolism written by Bevan Gang and published by . This book was released on 2014 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Warburg effect occurs in 90% of tumors, where glycolysis is favored despite the presence of oxygen. The activity of pyruvate dehydrogenase kinases (PDKs) is increased in cancer cells, suppressing glucose oxidation. Inhibition of PDKs can redirect glucose flux into the mitochondria, reversing the Warburg effect. Dichloroacetate (DCA) is a relatively non-toxic PDK inhibitor that inhibits all four isoforms of PDK with differing potency. We examined the determinants of DCA sensitivity, the ability of DCA to enhance apoptosis, and how DCA regulates cell metabolism. We found in a range of cancer types, that all four PDK isoforms can be expressed and contribute to tumor metabolism. DCA inhibited cancer cell growth in vivo and in vitro, activated PDH and reduced lactate production. The magnitude of DCA growth inhibition correlated with the PDK expression profiles of the cells, with PDK3 (highest Ki for DCA) conferring low sensitivity towards DCA. PDK2 siRNA-knockdown inhibited growth to a similar extent to DCA, whilst PDK3 knockdown significantly increased sensitivity to DCA, confirming sensitivity to DCA is determined by PDK expression. Further examination of PDKs in patient samples will increase the likelihood of DCA being successfully translated into clinical use, with the PDK expression profile being a biomarker for sensitivity to DCA. The mechanisms by which DCA can sensitize cancer cells towards apoptosis were investigated, as we observed that DCA increased hypoxia-induced apoptosis. DCA enhanced the effects of 4-(N-(S-penicillaminylacetyl)amino) phenylarsonous acid (PENAO; a novel anti-mitochondrial agent) in vitro. DCA increased ROS levels, which were fully responsible for enhancing PENAO apoptosis in MDA-MB-231 cells, but only partially in T-47D cells. The two cell lines were metabolically distinct, potentially explaining the different mechanisms by which DCA enhanced apoptosis. PDK knockdown experiments revealed that DCA could enhance apoptosis via off-target effects. The pro-apoptotic proteins Noxa and Puma were investigated, however DCA did not alter their expression. DCA however depolarized the mitochondrial membrane potential in T-47D cells, suggesting that this is an additional mechanism of DCA apoptosis enhancement in these cells. Nevertheless, DCA sensitized all cancer cell lines tested towards apoptosis. Thus DCA has potential to be used in combination with other cytotoxic agents in order to reduce their adverse effects. To understand the mechanism of action, the metabolic effects of DCA on cancer cells were investigated. Gas chromatography-mass spectrometry metabolomics revealed a general trend of increase in the proportion of anabolic metabolites upon DCA treatment. Furthermore, long-term DCA treatment resulted in DCA-resistance, which was accompanied by correlating changes in the PDK expression profile. These findings thus open avenues of further exploration on the mechanism of DCA action and resistance factors. Our findings provide potential biomarkers for sensitivity to DCA, and evidence that DCA can be combined with other therapies for enhanced anti-cancer effects. We have opened future directions of identifying DCA-resistance factors. This will allow using drugs in combination with DCA that specifically target these resistance factors. Collectively our work will allow DCA to have greater success in clinical trials by being able to target patients most likely to respond.

Download or read book Tumor Metabolome Targeting and Drug Development written by Steven Kanner and published by Springer Science & Business Media. This book was released on 2014-01-07 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, the major metabolic alterations identified in cancer and tumor-associated cells are explored, including discussions of former and emerging approaches to drug development in targeting cancer cell metabolism. The metabolic network in cells promotes the generation of both energy and biomass needed for them to grow, divide and differentiate. However, the metabolism of malignant cells generally varies from that of normal cells. These differences provide a platform for the discovery of new approaches to targeting potential vulnerabilities in cancer cells for therapeutic options Some of the significant changes that occur involve ATP production and consumption that modulates the ATP to ADP ratio, hypoxia and the effects of reactive oxygen species on glycolysis, regulation of mitochondrial respiration, induction and suppression of autophagy, and the Warburg effect and “reverse” Warburg effect--these topics and more are discussed in this volume.

Available in PDF, EPUB and Kindle. Book excerpt: Targeted cancer metabolic pathway anti-cancer drugs achieved great success in malignant cancer treatment, however, inevitably the effect of almost all these drugs is compromised by the development of resistance. Given that recent evidence shows cancer cell metabolic reprogramming occurs after drug treatment, probably, there is a strong relationship between a specific target and particular metabolic pathway remodeling. Understanding the hidden fact and mechanisms under cell metabolism modulated by specific drug targets (in particular those related to precision medicine) may lead to the development of new therapeutic strategies to overcome drug resistance.
