This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Obesity is a multi-factorial metabolic disease, resulting in increased adipose tissue acquisition by the host. This disease increases the risk for developing co-morbidities, including Metabolic Syndrome and other disorders such as breast cancer. Obesity, and particularly abdominal obesity, is characterised by metabolic changes, including chronically elevated insulin concentrations and aberrant secretion of cytokines released from fat tissue, called adipokines. Epidemiologically, the risk of developing postmenopausal breast cancer is increased in obese individuals. The molecular link between obesity and breast cancer however is not well understood. The study presented here aimed at identifying the molecular mechanisms involved in this link, by testing the hypothesis that high insulin concentration and certain adipokines may promote breast cancer progression and/or breast cancer aetiology. A cell culture system of breast cancer cells and breast epithelial cells was employed to investigate changes in cell proliferation, activation of cell signalling pathways, cell cycle progression and apoptosis after treatment with insulin, leptin, TNF-[alpha], adiponectin and IL-6. In MDA-MB-231 breast cancer cells, insulin treatment did not affect cell proliferation, cell cycle or apoptosis. Conversely, IR-phosphorylation, AKT-phosphorylation and ERK1/2-phosphorylation were all significantly increased. Microarray analysis indicated several important changes in gene expression with insulin treatment. Leptin treatment increased proliferation by 21%. Additional analyses of the effect of leptin indicated that neither the PI3-kinase pathway nor the MAP-kinase pathway was involved in mediating this effect. Treatment with TNF-[alpha] increased apoptosis, but did not affect cell proliferation or activation of cell signalling pathways. In MCF-10A breast epithelial cells, cell proliferation increased after insulin treatment by 180%. IR-phosphorylation, AKT-phosphorylation and ERK1/2 phosphorylation were all significantly increased while early apoptosis decreased after insulin treatment. Analysis of cell cycle however did not indicate a change in progression. Microarray analysis indicated that insulin treatment may increase expression of genes related to cancer growth. Leptin treatment increased cell proliferation and also increased ERK1/2-phosphorylation, while AKT-phosphorylation was not affected. Leptin did not change cell cycle progression. TNF-[alpha] treatment increased cell proliferation and also increased ERK1/2 phosphorylation, while AKT-phosphorylation was not changed. TNF-[alpha] treatment tended to increase apoptosis, the change however was not statistically significant. In SK-BR-3 breast cancer cells, cell proliferation did not change after insulin treatment. IR-phosphorylation and AKT-phosphorylation increased after insulin treatment, while ERK1/2-phosphorylation decreased. Gene expression of cyclin D and cyclin E increased with insulin treatment, while apoptotic rate and cell cycle profile were also not affected. Cell proliferation increased by 115% after treatment with 100 ng/ml leptin. ERK1/2-phosphorylation however decreased, while AKT-phosphorylation tended to increase, but the change was not statistically significant. Cell cycle profile was not affected by leptin treatment, G1-phase however tended to increase, but the change was again not statistically significant. Cell proliferation increased by 59% after 48 h treatment with 10 ng/ml TNF-[alpha]. AKT-phosphorylation and ERK1/2-phosphorylation increased with TNF-[alpha] treatment. Cell cycle analysis showed a decrease in S-phase and G2-phase, indicative of a decrease in cell cycle progression. These results indicate that none of the examined obesity-related factors is convincingly identified as the main molecular link between obesity and postmenopausal breast cancer. Conversely, all treatments affected each of the cell lines in, at least, one of the examined aspects. This indicates that many of the obesity-related factors may affect breast cancer and that a single breast tumour may utilise a unique combination of those factors to promote growth. All treatments increased proliferation in MCF-10A breast epithelial cells, with additional analysis generally supporting growth promotion. Insulin treatment particularly increased cell proliferation, while leptin and TNF-[alpha] increased MAP-kinase signalling. This may indicate that insulin and adipokines may have a higher impact on breast cancer aetiology than on breast cancer progression.
Download or read book Insulin Resistance and Cancer written by I. George Fantus and published by Springer Science & Business Media. This book was released on 2011-08-19 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the epidemiological associations between insulin resistance and cancer. This is followed by reviews of animal models which support this relationship and provide insight into potential mechanisms. Several chapters then provide detailed examination of the cellular and molecular changes characterizing the insulin resistant state, such as hyperinsulinemia, abnormal metabolism and hormone signaling, and how these interact with various tumor characteristics. For example some tumors present increased quantities of the fetal form of the insulin receptor, unique regulation of oxidative (Krebs’ cycle) metabolism (Warburg effect), as well as mutations in various relevant signaling pathways. Finally, the clinical implications of these data are integrated with considerations of insulin “sensitization” and potential metabolic interventions to prevent and treat cancer. It should be noted that while a number of cancers are associated with obesity the authors here have focused primarily on breast cancer as a key and significant model.
Download or read book Weight Control and Physical Activity written by Harri Vainio and published by IARC. This book was released on 2002 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avoiding overweight and obesity is the best-established diet-related risk factor for cancer. The proportion of people who are overweight/obese is increasing, and the amount of physical activity is decreasing in most populations, including urban populations in many developing countries. The increasing prevalence of overweight/obesity is presumably due to the increasing availability of highly palatable, high-energy foods, and an increasing sedentary lifestyle due to mechanisation of both workplace and leisure activities. Overweight/obesity and reduced physical activity increases the risk of cancers in various organs. Maintaining a healthy body weight and regular physical activity is the second most important way to prevent cancer, after tobacco control. The suggestions of possible public health actions to tackle these risk factors include the promotion of balanced diets, which are not excessive in energy, and broad education and planning to enable and encourage physical activity during work and leisure. Recommendations and a full discussion of these topics are included in the sixth volume in this series of Handbooks.
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.
