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.

This reference book, which is the second volume of Targeting Oxidative Stress in Cancer, explores oxidative stress as the potential therapeutic target for cancer therapy. The initial chapters discuss the molecular mechanisms of oxidative stress and its effects on different signaling pathways. Subsequently, the sections examine the impact of redox signaling on tumor cell proliferation and consider the therapeutic potential of dietary phytochemicals and nutraceuticals in reactive oxygen species (ROS)-induced cancer. In turn, it examines the evidence supporting the use of Vitamin C in cancer management, before presenting various synthetic and natural compounds that have therapeutic implications for oxidative stress-induced cancer. It also explores the correlation between non-coding RNA and oxidative stress. Furthermore, the book summarizes the role of stem cells in ROS-induced cancer therapy and reviews the therapeutic applications of nanoparticles to alter redox haemostasis in cancer cells. Lastly, it explores heat-shock proteins, ubiquitin ligases, and probiotics as potential therapeutic agents in ROS-mediated cancer. This book is a useful resource for basic and translational scientists as well as clinicians interested in the field of oxidative stress and cancer therapy. ​

This book offers a systematic review of the cutting-edge knowledge in stress medicine. Cellular redox imbalance, resulting from overproduction of reactive oxide species (ROS), leads to oxidative stress and subsequent occurrence and development of many diseases, such as cancer, diabetes, pain, etc. In addition, ROS can induce post-translational modification of proteins and play roles through redox signaling pathways. In this book, the authors attempt to re-define the key concepts in oxidative stress, such as oxidative eustress and oxidative distress, revisit the pivotal signaling of oxidative stress in human diseases, and discuss the debate in current anti-oxidant strategies, such as natural products and drug repurposing. This book serves as a reference to graduate students and researchers in this growing field.

The next generation of oncological hyperthermia involves the medical innovation of selectively heating up the malignant cells of the body in a controlled way. The easily-distinguishable biophysical and physiological characteristics of cancer cells and their immediate environment are the focus of the targeted energy delivery of this treatment. This heterogenic heating concept breaks with the homogeneous nature of conventional hyperthermia, where an isothermally equal temperature is applied to the large surface area of a solid tumor. Due to its selectivity, the new concept enables the usage of a significantly lower energy, making it safer, less toxic, and easier to use. This book shows the challenges facing oncological hyperthermia, and highlights clinical results obtained in various countries. It also presents discussions about the theoretical basis of the method, adding some technical discussions and clarifying the most difficult points of its design. The contributions dealing with clinical results use state-of-art conventional therapies with complementary hyperthermia and show the advantages of such a combination.

Cell differentiation and the development of multicellular organisms are processes of self-assembly, controlled and driven by signaling molecules and cascades including redox regulation. These reactions may have provided the energy for the first metabolic steps in the evolution of life. Today, redox modifications are established as important regulatory events in cellular functions including differentiation and development. Redox modifications of single cysteines regulate differentiation of stem cells, formation of functioning organs, and de-differentiation such as formation of cancer cells. Current cancer therapy is based on redox events as well and regeneration often reactivates developmental pathways. Understanding differentiation and de-differentiation on a molecular level is therefore a prerequisite for the continuing development of new medical therapies. This book summarizes the roles of redox regulation in development by bringing together different concepts and comparing similarities and differences between various cell types and species. An international team of contributors presents several new aspects of redox-regulated differentiation and de-differentiation, including aspects of redox medicine. Key Features Provides the first summary on this important topic Reviews redox-dependent development of model organisms and single organs Highlights the redox-regulated pathways important for differentiation processes Illustrates the potential of redox medicine Combines state-of-the-art knowledge in differentiation/development, aging/longevity, and repair/regeneration Written by leading experts in the field Related Titles Ayyanathan, K., ed.

This textbook describes in detail the process of cancer metastasis from a single cell in the primary site through its arduous journey to the sentinel lymph node as the main gateway and beyond to distant sites. The most up-to-date knowledge on key topics in the molecular biology, diagnosis, and treatment of metastatic cancer is highlighted by a large panel of experts. The book begins with a comprehensive overview of the genetic and molecular mechanisms that promote or inhibit cancer metastasis through lymphatic pathways to lymph nodes or through vascular pathways to distant sites, providing the reader with an essential basic knowledge. This is followed by further details on the role of the immune system within the primary tumor and the lymph node and the importance of the microenvironment at the metastatic site. The role of the sentinel lymph node in cancer metastasis is emphasized. Special attention is also given to state-of-the-art imaging techniques for the detection of early-stage cancer and cancer metastases, as well as the use of liquid biopsies in sarcoma, prostate, gastrointestinal, and lung cancer. Clinical patterns of malignant tumors arising in different organ systems are compared, described, and discussed with the goal of determining what similarities and/or differences exist. The book concludes with a detailed discussion of surgical intervention, radiation, and systemic therapy of primary and metastatic cancer, and briefly previews several emerging topics, such as the latest findings on personalized cancer therapy, cancer stem cells, unique molecular mechanisms of virus-induced cancer, the impact of the microbiome on cancer metastasis and the application of artificial intelligence in cancer metastasis research. By providing fundamental knowledge of the biological and clinical aspects of cancer metastasis, this book will be an important reference for cancer researchers, clinical oncologists, teachers, and students. Written by experts in the field, each chapter includes a summary of the chapter's key points and open-ended questions that address pressing issues in the field and encourage the reader to consider future directions.
