The sirtuin family of proteins (SIRT1-7) received a lot of attention in recent years as they serve as metabolic sensors that control not only metabolism, but also aging and lifespan regulation. As such, sirtuins are strong targets for the treatment of age-related metabolic diseases, including obesity, diabetes, and cancer. Indeed, many research groups as well as pharmaceutical companies discovered food components and/or drugs that target the sirtuins and provide significant health benefits. This book focuses on various aspects of sirtuin biology, from basic biochemistry, via molecular function, to its role in (fighting) human disease.

This book is ideal for pharmaceutical companies as they develop novel targets using sirtuins for metabolic diseases, cancer and neurodegenerative illnesses. Sirtuins are a diverse family of proteins, with several members in mammals. The functional diversity of sirtuins is rather broad, and they have been implicated in various central biological processes. Thus, they are also highly relevant in the context of various human diseases, from cancer to neurodegeneration. Covers both the general and specific aspects of sirtuin proteins and their role in biology, aging and disease Presents a top quality collection of leading experts who contribute on a wide range of sirtuin-related topics Ideal resource for pharmaceutical companies as they develop novel targets using sirtuins for metabolic diseases, cancer and neurodegenerative illnesses

Sirtuins comprise a family of NAD+-dependent enzymes that have been shown to impact longevity in a number of eukaryotic organisms. Sir2 (Silent Information Regulator 2) was the first sirtuin protein discovered. The discovery that Sir2 requires NAD+ for its activity suggested a link between Sir2 activity and the phenomenon of caloric restriction in prolonging longevity. This link was strengthened by the observation that lifespan extension by caloric restriction requires Sir2 protein. Under conditions of caloric restriction, NAD+ levels are high, Sir2 is activated, and the rate of aging is decreased. These effects have been replicated in invertebrate organisms, where a close structural and functional homologue of Sir2 was found in C. elegans and Drosophila. The sirtuin-dependent effects on metabolism and ageing, observed in lower organisms, have ignited intensive investigation of their biological and therapeutic roles in mammals. There are seven known mammalian sirtuins, SIRTs 1-7, the most studied of which is SIRT1, a close structural and functional homologue of yeast Sir2. Enhancement of organismal longevity and other health-promoting effects of mammalian SIRT1 have frequently been attributed to the regulation of metabolism. A recognized molecular link between metabolism and aging stimulated a firestorm of investigations, aiming to combat metabolic and age-dependent human diseases. It has become clear, however, that the sirtuin family of proteins regulates a diverse repertoire of cellular functions in mammals. Mounting evidence implicating SIRT1 in important clinical indications, such as diabetes, cancer, cardiovascular dysfunction and neurodegenerative disease, suggest that modality as attractive therapeutic target. Subsequently, drug discovery and development, targeting sirtuin activation, has been intensified in the recent years. Despite rapid progress and accumulation of new data, the biological roles of other mammalian sirtuins have been less studied and remain poorly understood. There are several important questions that remain to be addressed. What are the functions of sirtuins in different cell types and tissues? Are all sirtuins involved in the regulation of metabolism and aging? What is the functional relationship between different sirtuins? What are the mechanisms of regulation of sirtuin activities? What is the role of sirtuins in disease and therapy? This issue aims to address these and other critical questions, relevant to Research Topic on sirtuin biology and therapeutics. To that end the issue solicits expert opinions of sirtuin research on structural biology, biochemistry, cell biology, animal genetics, pharmacology, medicinal chemistry and drug discovery, and on areas of investigation studying human conditions, like diabetes, cancer, cardio-vascular, and neutodegeneration. Of particular interest are the new methods and assays to study sirtuins in various organisms and developing sirtuin-based therapeutics. Furthermore, we propose to encourage contributors to discuss new concepts and paradigms, and to express their perspectives on the future development of the sirtuin research field. Altogether, we believe this issue provides a unique opportunity for comprehensive and diverse coverage of the topic, and will be of broad interest for the journal’s readership.

Sirtuin Biology in Medicine: Targeting New Avenues of Care in Development, Aging, and Disease provides a fascinating and in-depth analysis of sirtuins in the body during normal physiology as well during disease highlighting the targeting of sirtuin-controlled pathways for the development of innovative, efficacious, and safe therapeutic strategies for multiple disorders in the body that ultimately can affect lifespan extension. Sirtuins are expressed throughout the body, have broad biological effects, and can significantly impact both cellular survival and longevity during acute and long-term illnesses. These histone deacetylases play an intricate role in the pathology, progression, and treatment of several disease entities ranging from neurodegenerative disorders, cardiovascular disease, immune system dysfunction, reproductive dysfunction, endocrine disorders, gastrointestinal disease, drug dependency, and aging-related disorders. Implementing a translational medicine format, this unique reference highlights novel signaling pathways for sirtuins that promote stem cell proliferation, enhance cellular protection, modulate pathways of apoptosis and autophagy, and extend life span.

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.

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.
