This book was released on 2017 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer metabolism is an emerging research area in cancer biology and therapeutics. One of the major metabolic pathways known to play important roles in the pathogenesis of cancer is one-carbon (1-C) metabolism. 1-C metabolism integrates the status of many dietary nutrients as inputs, and in turn regulates a variety of cellular processes including de novo nucleotide synthesis, lipid metabolism, protein biosynthesis, redox metabolism, transsulfuration, and epigenetics. As the regulation of these cellular processes is critical to cells, the tuning of the activity of 1-C metabolism plays important roles in cancer. Previous studies have established implications of genetic and dietary perturbations of multiple components of 1-C metabolism in human cancers. However, the heterogeneity among cancer types and subtypes with respect to the usage and flux distribution of 1-C metabolism has not been systematically quantified. There remain great potentials in deciphering how 1-C metabolism plays different roles in different human cancers, especially since this metabolic pathway is targeted by a number of the existing antimetabolite chemotherapeutic agents. In this dissertation, I quantitatively characterize various aspects of 1-C metabolism across human cancers. I first investigate the between-cancer-type variation in the usage of serine by 1-C metabolism using flux distribution analyses and find substantial heterogeneity. I also show that a common feature across cancers is correlated activation of nucleotide and redox metabolism. Next I assess the link between 1-C metabolism and DNA methylation using computational modeling and machine-learning. I find significant contribution from particular enzymes within 1-C metabolism - such as methionine adenosyltransferases - in explaining the within- cancer-type (inter-individual) variation in DNA methylation. My results provide evidence that misregulation of 1-C metabolism is at least in part responsible for disrupted DNA methylation profiles in tumors leading to epigenetic instability and higher malignancy. Given evidence for the role of 1-C metabolism and the methionine cycle in methylation dynamics, I next evaluate the potential for dietary intervention using the amino acid methionine. To this end, I model human serum methionine levels and quantify the contribution of various factors in determining the concentration of methionine. I discover that dietary factors could together explain nearly 30% of overall variation in methionine concentrations, and also provide evidence that the relationship between 1-C metabolism and methylation exists at physiological concentrations of methionine. Finally, I use a novel approach to identify gene expression markers of tumor response to 5-FU and Gemcitabine - two of the commonly used antimetabolite chemotherapies that target enzymes in 1-C metabolism. I discover that response to these agents is to a large degree determined by the metabolic state of tumors and the expression levels of specific target pathways of each of these agents. Together, my findings provide quantitative information about the heterogeneity among tumors with respect to the usage of 1-C metabolism, and delineate some of the ways this information can be translated into clinical decision- making. ...

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.
Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Download or read book Review of the Department of Energy s Genomics GTL Program written by National Research Council and published by National Academies Press. This book was released on 2006-04-19 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Energy (DOE) promotes scientific and technological innovation to advance the national, economic, and energy security of the United States. Recognizing the potential of microorganisms to offer new energy alternatives and remediate environmental contamination, DOE initiated the Genomes to Life program, now called Genomics: GTL, in 2000. The program aims to develop a predictive understanding of microbial systems that can be used to engineer systems for bioenergy production and environmental remediation, and to understand carbon cycling and sequestration. This report provides an evaluation of the program and its infrastructure plan. Overall, the report finds that GTL's research has resulted in and promises to deliver many more scientific advancements that contribute to the achievement of DOE's goals. However, the DOE's current plan for building four independent facilities for protein production, molecular imaging, proteome analysis, and systems biology sequentially may not be the most cost-effective, efficient, and scientifically optimal way to provide this infrastructure. As an alternative, the report suggests constructing up to four institute-like facilities, each of which integrates the capabilities of all four of the originally planned facility types and focuses on one or two of DOE's mission goals. The alternative infrastructure plan could have an especially high ratio of scientific benefit to cost because the need for technology will be directly tied to the biology goals of the program.

Download or read book The Chemistry of Microbiomes written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-07-19 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 21st century has witnessed a complete revolution in the understanding and description of bacteria in eco- systems and microbial assemblages, and how they are regulated by complex interactions among microbes, hosts, and environments. The human organism is no longer considered a monolithic assembly of tissues, but is instead a true ecosystem composed of human cells, bacteria, fungi, algae, and viruses. As such, humans are not unlike other complex ecosystems containing microbial assemblages observed in the marine and earth environments. They all share a basic functional principle: Chemical communication is the universal language that allows such groups to properly function together. These chemical networks regulate interactions like metabolic exchange, antibiosis and symbiosis, and communication. The National Academies of Sciences, Engineering, and Medicine's Chemical Sciences Roundtable organized a series of four seminars in the autumn of 2016 to explore the current advances, opportunities, and challenges toward unveiling this "chemical dark matter" and its role in the regulation and function of different ecosystems. The first three focused on specific ecosystemsâ€"earth, marine, and humanâ€"and the last on all microbiome systems. This publication summarizes the presentations and discussions from the seminars.

This book was released on 2012-12-06 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is evident that biochemical control is not strictly hierarchical and that intermediary metabolism can contribute to control of regulatory pathways. Metabolic studies are therefore increasingly important in gene function analyses, and an increased interest in metabolites as biomarkers for disease progression or response to therapeutic intervention is also evident in the pharmaceutical industry. This book offers guidelines to currently available technology and bioinformatics and database strategies now being developed. Evidence is presented that metabolic profiling is a valuable addition to genomics and proteomics strategies devoted to drug discovery and development, and that metabolic profiling offers numerous advantages.
