Metabolic programs of individuals are key determinants for disease susceptibility and immune response. This book, edited by experts in the field, summarizes epigenetic signaling pathways that regulate metabolic programs associated with cancer and cancer-related secondary diseases. The first part of the book highlights key metabolic pathways that are implicated in cancer and provides a comprehensive overview on the carbohydrate, protein, lipid, amino- and nucleic acid metabolic pathways that are deregulated in cancer. Special attention is paid to the altered tumor micro-environment that is influenced by the metabolic milieu. Furthermore, the fundamental relationship between the cellular metabolic environment and cell death-mediated autophagy is discussed. The second part of the book covers our understanding of the fundamental epigenetic regulations that are implicated in controlling the metabolic programs in cancer cells. Many aspects of epigenetic regulation of non-coding RNAs as well as DNA/RNA methylation, which influencing metabolic homeostasis in cancer, are discussed in detail. Special emphasis is placed on the epigenetic regulation of the amino acid, glucose/carbohydrate metabolism and epigenetic regulation during hypoxia and its connection to cancer. Last but not least, the third part of the book covers small molecule modulators of histone modifying enzymes, which can be used as therapeutic tools. The readers learn about the cross-talk between epigenetics and immunometabolims, as well as the epigenetic regulation of oncometabolites to combat cancer. Given its scope, the book will appeal to a broad readership interested in epigenetic, cancer and metabolic research.

Histone deacetylase inhibitors (HDI) have been largely known for their ability to induce cell cycle arrest and apoptosis of tumor cells, effects that have translated into clinically significant antitumor activity against certain malignancies. In addition, there is now increasing evidence that HDIs are also endowed with immunoregulatory properties. Interestingly, while some reports have highlighted the anti-inflammatory effects of these compounds, others have shown pro-inflammatory effects triggered by HDIs in in vitro and in vivo studies. Known targets for HDIs are histone deacetylases (HDACs), enzymes that are recruited to gene promoters where they regulate transcription through histone modifications. Some HDACs, however, can also deacetylate nonhistone proteins, indicating that the role of HDACs in cell biology goes beyond their initial described effects on histones and encompasses now more complex regulatory functions. This complexity, along with the fact that most of the HDI currently in use are pan-HDI (multiple HDAC targets), might explain the divergent immunoregulatory effects of these compounds. Given this conundrum, in this chapter we have summarized the current understanding of the expression/function of specific HDACs in immune cells, knowledge that is providing important insights into their role in immunobiology and also paving the way for the development of more selective and potentially less toxic epigenetic-based approaches to effectively harness antitumor immune responses.

This book offers a broad overview of the concepts and research findings in immunometabolism. The immune system is made up of numerous different cell types, pathways, and components that must be able to respond rapidly to a pathogen or cancer, but must also remain quiescent in the absence of challenges. Immune cells rely on metabolic pathways to adapt to changing environments and stimuli. Additionally, these cells can be modified in function or fate by fluctuations in available nutrients. The chapters in this book describe ways in which immune cells utilize and are regulated by metabolic pathways. Topics include how immune-cell metabolism shapes immune homeostasis, and how dysregulation of these pathways can lead to immune disorders. In different contexts, such as a tumor microenvironment, immune-cell function and identity may be modified not only by cytokines and checkpoint molecules, but also by nutrient availability and other metabolic stimuli. Transcriptional reprogramming confers many of the changes in immune cell metabolism that are seen when a T-cell, for example, undergoes activation or functional adaptation to different environments. Lastly, immune cells can destructively or protectively participate in human metabolic homeostasis or disorders. This book summarizes immune-metabolism from a variety of different perspectives, including the ways in which metabolic cues, pathways, and requirements of immune cells change in conditions of homeostasis and activation. The exploration of the significance of metabolic checkpoints and other cues, particularly in the context of cancer and immune disorders, may form the foundation for the development of therapeutics.

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.

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.

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.
