Download or read book The Metabolic Plasticity of Lipid Synthesis in Cancer Cells written by Avi Kumar and published by . This book was released on 2021 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The metabolic network has evolved over millennia into an intricate system of reactions which maintain cellular homeostasis. Highly proliferative cells, including cancers, reprogram the network to sustain elevated biomass accumulation. Lipid metabolism, in particular, is critical to support growth as these complex molecules serve numerous essential roles in cell biology. The chapters of this thesis are all independent bodies of work which explore mechanisms of fatty acid reprogramming in mammalian cells as well as present software tools which expedite analysis of metabolic studies. Chapter 1, titled "Profiling fatty acid metabolism in cancer cells using stable isotope tracing" is a review of relevant literature concerning the rewiring of central carbon and lipid metabolism under highly proliferative disease states as well as the utility of stable isotope tracing and metabolic modeling. Chapter 2, titled "NaCT/SLC13A5 facilitates citrate import and metabolism under nutrient-limited conditions" quantifies the contribution of NaCT-mediated citrate uptake to central carbon metabolism in multiple cell systems. The findings demonstrated that citrate uptake promoted lipogenesis and proliferation in glutamine deprived conditions, as well as increased tolerance to zinc-induced toxicity. Chapter 3, titled "ATP-citrate lyase deficiency highlights critical sources of lipogenic acetyl-CoA in cancer cells" describes how multiple layers of redundancy support lipogenic acetyl-CoA synthesis. Cells were found to rely on non-canonical sources of acetyl-CoA including de novo acetate synthesis, and peroxisomal b-oxidation when deficient in functional ATP-citrate lyase (ACLY). Chapter 4, titled "Escher-Trace: A Web Application for Pathway-Based Visualization of Stable Isotope Tracing Data" describes a web-based visualization platform for analyzing stable isotope tracing data with the context of metabolic pathway architecture. The software simplifies the analytical pipeline for nominal resolution stable isotope tracing measurements, by automating multiple intermediary steps including natural isotope correction and data plotting. Chapter 5, titled "Analysis of high-resolution lipidomic data with Escher-Trace" details an analytical pipeline for analysis of high-resolution mass spectrometry (HRMS) data which incorporates the Escher-Trace platform. By expanding the feature set of Escher-Trace and introducing an intermediary script connecting the platform to existing HRMS analysis software, the pipeline is found to expedite analysis of complex HRMS datasets. Overall, these findings reveal compensatory mechanisms employed upon disruption of canonical lipogenesis as well as provide tools which contextualize stable isotope tracing data and facilitate analysis of metabolic studies.

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 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 Lipid Metabolism in Tumor Immunity written by Yongsheng Li and published by Springer Nature. This book was released on 2021-03-19 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on lipid metabolism in tumor immunity, covering the application of lipidomics in tumor immunity and all aspects of lipid metabolism in tumor microenvironment. During the progression of tumors, tumor cells and immune cells interact in a dynamic microenvironment. Targeting the immune system has a high potential for treating cancer. However, due to the high heterogeneity of the tumor microenvironment, only a small percentage of patients experience such clinical benefits of tumor immunotherapy. Therefore, understanding the tumor microenvironment is crucial for tumor immunity. Recently, lipid metabolism is an emerging research direction and contributes to cell survival and biofunctions in tumor microenvironment, which is of great interest and significance to be elucidated. This book provides the doctors, researchers, and scientists with a cutting-edge overview of the lipid metabolism and its role in tumor immunity. It also yields benefits for pharmaceutical companies regarding drug discovery.

Download or read book Fatty Acid Metabolism as a Tumor Marker written by Gatot Nyarumenteng A Winarno and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer cells tend to make metabolism changes in the human body for their growth and survival. One of the most interesting changes is the alteration of fatty acid metabolism in order for the high rate of fatty acid synthesis required to increase the level of fatty acids needed for cancer cell proliferation. Thus, the reprogramming of fatty acid metabolism is needed for cancer cell survival. Fatty acid metabolic reprogramming is one of the hallmarks of the cancer condition since it can affect cellular functions. The reprogramming of fatty acid synthesis includes increased exogenous fatty acid uptake, de novo fatty acid synthesis, and oxidation of fatty acids. Identifying biochemical targets in fatty acid metabolism is useful for diagnosing and predicting the therapeutic efficiency in tumor treatment.

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.
