Available in PDF, EPUB and Kindle. Book excerpt: Obesity is an established risk and progression factor for many types of cancer, including pancreatic and colon cancer, and is characterized by abnormal metabolic hormone production and a chronic low-grade state of inflammation. However, the links between obesity, hormones, inflammation and tumorigenesis in colon and pancreatic tissue are poorly understood. Calorie restriction (CR), an anti-obesity dietary regimen with potent anticancer effects, reduces serum metabolic hormones and protumorigenic cytokines. Insulin-like growth factor (IGF)-1 is a metabolic hormone that activates NF-[kappa]B, a key regulator of inflammation. NF-[kappa]B is a transcription factor that mediates transcription of many cancer- and inflammation-related genes and is upregulated in both colon and pancreatic cancer. We hypothesized that CR inhibits colon and pancreatic tumor cell growth through modulation of hormone-stimulated NF-[kappa]B activation and protumorigenic gene expression. To test this hypothesis, we used CR and ad libitum feeding to generate a lean and overweight (control) phenotype, respectively; in C57BL/6 mice transplanted with MC38 colon cancer cells or Panc 02 pancreatic cancer cells, and analyzed the effect of diet on circulating hormone levels, markers of inflammation, and tumor growth. We also investigated the in vitro effects of IGF-1 on NF-[kappa]B activation and downstream protumorigenic gene expression in MC38 and Panc 02 cells. CR, relative to control diet, reduced body weight, circulating IGF-1 levels, and transplanted MC38 and Panc 02 tumor growth, as well as protumorigenic gene expression in the MC38 and Panc 02 tumor microenvironment. IGF-1 increased cell viability, NF-[kappa]B nuclear translocation and DNA binding, transcriptional activation, and downstream gene expression of inflammation and other protumorigenic genes in MC38 colon cancer cells and Panc 02 pancreatic cancer cells in vitro. Knockdown studies of NF-[kappa]B in Panc 02 cells using si-RNA established that the IGF-1-induced increase in protumorigenic gene expression is mediated, at least partially, through an NF-[kappa]B-dependent mechanism. In conclusion, these findings in models of pancreatic and colon cancer help clarify the links between obesity, IGF-1, NF-[kappa]B-mediated inflammation, and cancer. This work provides the underpinnings for several new molecular targets and strategies to test in model systems and translational studies for preventing or controlling obesity-related cancer.

Download or read book Obesity Inflammation and Cancer written by Andrew J. Dannenberg and published by Springer Science & Business Media. This book was released on 2013-05-21 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to its metabolic and endocrinologic effects, obesity and adipose tissue have now been shown to be associated with low grade inflammation resulting in cellular and humoral inflammatory factors of which the latter may act by endocrine, paracrine and autocrine mechanisms. These inflammatory mediators have increasingly been suggested as contributing to the obesity link to carcinogenesis and cancer promotion. This volume of Energy Balance and Cancer will focus on recent developments and cutting edge research pointing to inflammation and inflammatory factors as key mediators of this linkage. The volume first provides information on inflammation as an important link between obesity and insulin resistance, which is in itself linked to promotion of cancer through hyperinsulinemia. The volume then covers some of the most important mechanisms by which obesity leads to inflammation, including the novel inflammasome concept, alterations in chromatin structure, circulating inflammatory factors, unique cellular interactions between adipocytes and macrophages and the direct link of dietary fat to inflammation and cancer. Overall, this volume will provide important insight to help understand how inflammation may help modulate the linkage between obesity and cancer and serve as a platform for developing future research in this area.

Download or read book The Effects of Changes in Energy Balance on Immune Regulation and Tumor Progression in the 4T1 2 Mammary Tumor Model written by William Turbitt and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One significant challenge in the field of breast cancer (BC) research is to determine how to reduce and/or eliminate the mortality associated with metastatic BC. Novel therapies, especially non-pharmacological, lifestyle-based interventions that prevent or slow metastatic disease with less severe side effects are greatly needed. Numerous lifestyle factors (including dietary components, body weight, and physical activity patterns) significantly impact BC risk and survival. Emerging population data suggests an inverse relation between physical activity and BC incidence, as well as an important role for exercise in the prevention of cancer recurrence and mortality. The observational nature of these studies limit the ability to determine biological mechanisms and the extent to which exercise, as opposed to changes in body weight, drive beneficial effects. Additionally, very little is known about the mechanisms contributing to the relation between physical activity and survival. Given the importance of metastases in the mortality of women with BC, understanding the role of exercise on metastatic burden may reveal important new targets for secondary and tertiary cancer prevention. The aim of study one was to control for weight and examine the effects of exercise, mild dietary restriction, or the combination of diet and exercise on the inflammation-immune axis and tumor progression in a preclinical metastatic BC model to determine the extent to which exercise or body weight contribute to cancer prevention. Dietary energy restriction-induced weight control (i.e., SED+ER mice) was effective at altering host splenic immunity and the expression of key genes in the tumor microenvironment (TME) related to immunosuppression and metastatic progression; however, this intervention failed to induce changes in primary tumor growth or spontaneous metastases. Moderate exercise in weight stable mice (EX+ER) resulted in a similar reduction in immunosuppressive and metastatic genes in the TME compared with the SED+ER mice; however, in addition, EX+ER mice had the greatest reduction in splenic immunosuppressive cells and plasma insulin-like growth factor-1 (IGF-1). The effects of moderate exercise in weight stable mice culminated in a significant delay in primary tumor growth and spontaneous metastases, suggesting that exercise-induced alterations in metabolic drivers of tumorigenesis, not simply a change in body weight, underlie the protective effects in the dual intervention group. Interestingly the exercise-induced protective effect on the emergence of immunosuppressive factors and reduced tumor burden was lost when mice continued to gain weight over the course of the study, suggesting that weight gain-induced disturbances on hormonal, inflammatory, and/or immunological function can override the exercise-induced benefits. Collectively, study one provided a deeper understanding of the extent to which exercise, and changes in body weight, underlies cancer protection. Few researchers have examined the effect of energy balance interventions on the efficacy of immunotherapeutic strategies. Two subsequent studies were designed to investigate the response to emerging cancer therapeutics in mice randomized to an energy balance paradigm (i.e., sedentary, ad libitum, weight gain [WG] group vs. exercising, mild dietary restriction, weight maintenance [WM] group) to identify potential mechanisms and provide translational support. Study two aimed to determine if there were any additive effects of moderate exercise in weight stable mice and the therapeutic administration of a broad-based, allogeneic, whole tumor cell cancer vaccine (VAX). There was a significant effect of both WM and VAX alone on primary tumor growth; and an additive effect of WM+VAX on primary tumor growth, lung and heart spontaneous metastases, splenocyte count at sacrifice, the number of total splenic myeloid-derived suppressor cells (MDSCs) and granulocytic subset of MDSCs, and plasma levels of IGF-1. Splenic interferon gamma (IFN) secretion in response to re-stimulation with tumor antigens was significantly elevated in response to VAX and WM; however, there was no additive effect of WM+VAX. These results suggested that our whole tumor cell cancer vaccine augmented the weight maintenance (via diet and exercise) effects on primary tumor growth and spontaneous metastasis; and suggested that vaccination may provide an immune stimulus to further promote the protective effects of moderate exercise alone in the metastatic 4T1.2 mammary tumor model.Study three aimed to determine if there were any additive effects of moderate exercise in weight stable mice and the dual therapeutic administration of a whole tumor cell cancer vaccine and programmed cell death protein-1 (PD-1) checkpoint blockade. We observed a cancer prevention effect of PD-1 checkpoint blockade in WG mice on primary tumor growth and spontaneous lung metastasis. However, moderate activity in weight stable mice, independent of PD-1 checkpoint blockade, was effective in reducing primary tumor growth and metastatic burden. The WM+PD-1 group displayed the lowest number of splenic MDSCs and granulocytic MDSCs and maintained its splenic lymphoid populations. Neither the number of tumor-infiltrating immune cells, the effector or activation status of tumor-infiltrating CD4+ helper and CD8+ cytotoxic T cells, nor functional outcomes were significantly different between groups. PD-1 checkpoint blockade in WG mice, moderate exercise in weight stable mice, and PD-1 checkpoint blockade in moderately exercising, weight stable mice showed comparable, albeit subtle differences, in tumor-immune crosstalk gene expression markers that drive the expansion of immunosuppressive cell types and impact metastatic progression. The lack of responsiveness to VAX+PD-1 checkpoint blockade in WM mice suggests that moderate exercise in weight stable mice may be enhancing antitumor immunity and/or reducing protumorigenic factors (i.e., similar mechanisms mediated by VAX+PD-1 checkpoint blockade). Results from the current studies provided insight into the extent to which exercise in weight stable mice underlie cancer protection. Also, results provided insight into potential mechanisms by which exercise can act via the inflammation-immune axis to attenuate the generation of a protumorigenic and immunosuppressive TME. These data demonstrated that preventing weight gain through diet and exercise may be an important recommendation to maintain prolonged antitumor effector responses and improve clinical outcomes. Results from the current studies provided insight into potential mechanisms by which physical activity exerts primary and secondary cancer prevention effects and provides a biological rationale for randomized clinical trials to investigate physical activity strategies to prevent metastatic progression in BC survivors and ultimately improve survival outcomes.

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 Cancer as a Metabolic Disease written by Thomas Seyfried and published by John Wiley & Sons. This book was released on 2012-05-18 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the relationship between energy balance and obesity is essential to develop effective prevention programs and policies. The International Agency for Research on Cancer convened a Working Group of world-leading experts in December 2015 to review the evidence regarding energy balance and obesity, with a focus on low- and middle-income countries, and to consider the following scientific questions: (i) Are the drivers of the obesity epidemic related only to energy excess and/or do specific foods or nutrients play a major role in this epidemic? (ii) What are the factors that modulate these associations? (iii) Which types of data and/or studies will further improve our understanding? This book provides summaries of the evidence from the literature as well as the Working Group's conclusions and recommendations to tackle the global epidemic of obesity.

In the second part, the association between physical activity and cancer survivorship is addressed. The effects of physical activity on supportive care endpoints (e.g., quality of life, fatigue, physical functioning) and disease endpoints (e.g., biomarkers, recurrence, survival) are carefully analyzed. In addition, the determinants of physical activity in cancer survivors are discussed, and behavior change strategies for increasing physical activity in cancer survivors are appraised. The final part of the book is devoted to special topics, including the relation of physical activity to pediatric cancer survivorship and to palliative cancer care.

Download or read book Inflammation and Atherosclerosis written by Georg Wick and published by Springer Science & Business Media. This book was released on 2011-12-03 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been known for over 150 years that hallmarks of inflammation can be observed in the wall of atherosclerotic vessels. It was, however, not clear if this inflammation is the cause or the consequence of atherogenesis. More recently, it has become evident that inflammation mediated both by innate and adaptive immunity is instrumental even in the earliest stages of the development of atherosclerotic lesions, i.e., that it plays an important pathogenetic role. In this volume, international experts in the field discuss the pathogenetic, diagnostic, preventive and possible therapeutic relevance of inflammation in atherogenesis. This book is intended for researchers and physicians in the fields of vascular biology, immunology and atherosclerosis.

Download or read book Nutrigenomics written by Carsten Carlberg and published by Springer. This book was released on 2016-06-11 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fascinating area of Nutrigenomics describes this daily communication between diet, food and nutrients, their metabolites and our genome. This book describes how nutrition shapes human evolution and demonstrates its consequences for our susceptibility to diseases, such as diabetes and atherosclerosis. Inappropriate diet can yield stress for our cells, tissues and organs and then it is often associated with low-grade chronic inflammation. Overnutrition paired with physical inactivity leads to overweight and obesity and results in increased burden for a body that originally was adapted for a life in the savannas of East Africa. Therefore, this textbook does not discuss a theoretical topic in science, but it talks about real life, and our life-long “chat” with diet. We are all food consumers, thus each of us is concerned by the topic of this book and should be aware of its mechanisms. The purpose of this book is to provide an overview on the principles of nutrigenomics and their relation to health or disease. We are not aiming to compete with more comprehensive textbooks on molecular nutrition, evolutionary biology, genomics, gene regulation or metabolic diseases, but rather will focus on the essentials and will combine, in a compact form, elements from different disciplines. In order to facilitate the latter, we favor a high figure-to-text ratio following the rule “a picture tells more than thousand words”. The content of this book is based on the lecture course “Nutrigenomics”, which is held since 2003 once per year by Prof. Carlberg at the University of Eastern Finland in Kuopio. The book is subdivided into three sections and twelve chapters. Following the "Introduction" there are sections on the "Molecular genetic basis" and the "Links to disease", which take a view on nutrigenomics from the perspective of molecular mechanisms or from the causes of metabolic diseases, respectively. Besides its value as a textbook, Nutrigenomics will be a usefull reference for individuals working in biomedicine.
