Lactate is both a metabolite of glycolysis, and a component of several signaling pathways. Although recent studies indicate that lactate is a critical regulator of cancer development, very little is known about lactate metabolism in the context of metastatic cancer. Epithelial-to mesenchymal transition (EMT) promotes metastasis by inducing invasive properties in epithelial tumors. To determine whether EMT induces metabolic alterations, we have studied two epithelial breast cancer cell lines and their respective EMT-induced mesenchymal progeny for changes in lactate metabolism. Metabolic analysis revealed that EMT induced an enhanced glycolytic profile in mesenchymal breast cancer cells. In contrast, epithelial breast cancer cells preferentially use oxidative phosphorylation (OXPHOS) to produce ATP. The strong expression of the lactate importer MCT1 in epithelial breast cancer cells may involve the ERα-inducible GATA3 transcription factor. We detected a specific GATA3 binding site in the DNAse-hypersensitive region within the promoter of MCT1 gene and found that knockdown of GATA3 represses MCT1 expression. We also observed that the endogenous lactate receptor, G-protein coupled receptor 81 (GPR81), was highly expressed in epithelial breast cancer cell lines and hormone-positive breast cancer tumors. GPR81 regulated MCT1 expression and lactate uptake in epithelial breast cancer cells and its expression was crucial for cell proliferation and survival under nutrient-limited conditions. This study provides an overview of specific metabolic changes induced by EMT in two independent and substantially different epithelial breast cancer cell lines. In addition, we propose GPR81 as a potential prognostic marker and therapeutic target in hormone positive epithelial breast cancer.

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.

The book addresses controversies related to the origins of cancer and provides solutions to cancer management and prevention. It expands upon Otto Warburg's well-known theory that all cancer is a disease of energy metabolism. However, Warburg did not link his theory to the "hallmarks of cancer" and thus his theory was discredited. This book aims to provide evidence, through case studies, that cancer is primarily a metabolic disease requring metabolic solutions for its management and prevention. Support for this position is derived from critical assessment of current cancer theories. Brain cancer case studies are presented as a proof of principle for metabolic solutions to disease management, but similarities are drawn to other types of cancer, including breast and colon, due to the same cellular mutations that they demonstrate.

Ergebnisse von in vitro-Studien lassen vermuten, dass sich der pH-Wert in einem Tumor auf die Wirksamkeit von Chemo- oder Strahlentherapien auswirken kann. Wie aber sieht die Beziehung zwischen der Tumorentwicklung und dem pH-Wert aus? Können ein niedriger pH-Wert oder ein Sauerstoffmangel die Carcinogenese hemmen? Wo bieten sich therapeutische Ansätze? Anwort auf diese und andere Fragen finden Sie in diesem Band. In interdisziplinärer Weise wurden Beiträge aus der Grundlagenforschung und der klinischen Praxis zusammengetragen.

It was estimated that in 2008, 1,437,180 patients would receive a new cancer diagnosisand 565,650individualswould die of cancer (Jemal et al. 2008).Since the vast majority of patients dying of cancer will have had anticancer therapy, both c- ventional chemotherapy and novel targeted therapy, it can be concluded that these patients are dying with drug resistant cancer. The term multidrug resistance is also apt – in that these patients die after having undergone multiple rounds of different and structurally unrelated cancer therapies. However, for some, the concept of m- tidrug resistance is a worn out idea, stemming from disappointment with the drug resistancereversalstrategiesthatwerecarriedoutinthe1990susingpumpinhibitors to block drug resistance mediated by P-glycoprotein, product of the MDR-1 gene. However, if one takes the larger de?nition – multidrug resistance as simultaneous resistance to multiple structurally unrelated anticancer therapies – its existence c- not be denied. The purpose of this book is to explore new concepts related to drug resistance in cancer, including resistance to the new molecularly targeted agents. Perhaps new terminology is needed for resistance that occurs following therapy with the targeted agents: Novel Targeted Agent Resistance (NTR). Alternatively, we can return to the original de?nition of multidrug resistance as simply the res- tance to multipleagents that occurs in the course of normalcancer progression.This resistance is likely to be mediated by many factors.

CiteSpace is a freely available computer program written in Java for visualizing and analyzing literature of a scientific domain. A knowledge domain is broadly defined in order to capture the notion of a logically and cohesively organized body of knowledge. It may range from specific topics such as post-traumatic stress disorder to fields of study lacking clear-cut boundaries, such as research on terrorism or regenerative medicine. CiteSpace takes bibliographic information, especially citation information from the Web of Science, and generates interactive visualizations. Users can explore various patterns and trends uncovered from scientific publications, and develop a good understanding of scientific literature much more efficiently than they would from an unguided search through literature. The full text of many scientific publications can be accessed with a single click through the interactive visualization in CiteSpace. At the end of a session, CiteSpace can generate a summary report to summarize key information about the literature analyzed. This book is a practical guide not only on how to operate the tool but also on why the tool is designed and what implications of various patterns that require special attention. This book is written with a minimum amount of jargon. It uses everyday language to explain what people may learn from the writings of scholars of all kinds.
