Metabolic programs of individuals are key determinants for disease susceptibility and immune response. This book, edited by experts in the field, summarizes epigenetic signaling pathways that regulate metabolic programs associated with cancer and cancer-related secondary diseases. The first part of the book highlights key metabolic pathways that are implicated in cancer and provides a comprehensive overview on the carbohydrate, protein, lipid, amino- and nucleic acid metabolic pathways that are deregulated in cancer. Special attention is paid to the altered tumor micro-environment that is influenced by the metabolic milieu. Furthermore, the fundamental relationship between the cellular metabolic environment and cell death-mediated autophagy is discussed. The second part of the book covers our understanding of the fundamental epigenetic regulations that are implicated in controlling the metabolic programs in cancer cells.
