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.

Metabolism of glucose, lipids, amino acids, and nucleotides represents the fundamental capability of host to utilize distinct nutrients and energy to support diverse function of different cell lineages. Cancer cells undergo the Warburg Effect to adapt to the microenvironment composed by stromal cells and immune cells. The crosstalk among cancer cells and immune cells orchestrate tumor progression. In the tumor microenvironment, immune cells also show metabolic reprogramming. For example, naive or memory T cells switch from the oxidation of fatty acids to glycolysis and glutaminolysis after activation; meanwhile massive glucose and glutamine are transported into cells to meet their metabolic demands. Defective glucose or glutamine metabolism impairs the differentiation and expansion of helper T cells. The molecular pathways that control immune cell metabolism and function are intimately linked. Understanding such metabolic reprogramming of immune cells in the tumor microenvironment could offer new directions in manipulation of peripheral immune responses. Recent findings in immune cell metabolism hold the promising possibilities by metabolic manipulation of immune cells towards clinical therapeutics for treating cancer. This Research Topic includes updated findings and views in the metabolism of cancer cells and immune cells in the tumor microenvironment.

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.

Over the past decade, the tumor microenvironment has become one of the most important research areas in cancer biology, as cells within the tumor microenvironment, despite being outnumbered by healthy cells, are able to evade surveillance and immune-mediated destruction. While researchers have learned a great deal about the cellular and structural makeup of the tumor microenvironment, there has been a growing understanding of the metabolic interplay between the tumor micronenvironment’s various cellular constituents and how each of them contributes to overall tumor growth and metastases. This new volume will guide researchers, students, oncologists and academics through a rapidly developing and changing field with a thorough understanding of tumor microenvironment biology from a cellular, structural, metabolic, and immunological perspective.

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.

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.

One of the current challenges and failures of immunotherapy is in part due to the complex tumor microenvironment (TME) that provides a formidable barrier to immune infiltration and function. The TME consists of various cell types (tumor cells, fibroblasts, endothelial cells, and immune cells), soluble signaling molecules (cytokines, growth factors, and chemokines), and extracellular matrix. On another note, metabolic disturbances in various TME components, such as hypoxia, acidosis, lactate accumulation, and nutrient deprivation, can play a critical role in the tumor progression. Furthermore, genetic and epigenetic dysfunctions are known to be part of the characteristics of cancer development. The immune cells could have a pro- or anti-tumor role in the TME, and their activity might vary in the context of different cancers. Both innate and adaptive immune cells interact with tumor cells through direct contact or through chemokines and cytokines signaling, shaping the tumor's activity and response to therapy.
