Summary : With the rapid development of nanotechnology, nanomaterials have been widely applied in many industrial sectors, including medicine, consumer products, and electronics. While such technology has brought benefits and convenience to our daily lives, it may also potentially threaten human health. In some cases, nanomaterials present unexpected risks to both humans and the environment. Assessments of the potential hazards associated with nanotechnology have been emerging, but substantial challenges remain, because the large number of different nanomaterials cannot be effectively evaluated in a timely manner. The development of a good strategy for a nanomaterials hazard assessment not only promotes the more widespread adoption of non-rodent or 3Rs principles, but also makes nanotoxicology testing more ethical, relevant, and cost- and time-efficient. A thorough understanding of the mechanisms by which nanomaterials perturb biological systems is critical for a more comprehensive elucidation of their nanotoxicity, and this will also facilitate the development of prevention and intervention policies against adverse outcomes induced by them. We hope that the articles included in this eBook can provide updated knowledge on nanotoxicology and nanosafety, from the point of view of both toxicology and ecotoxicology.

Summary : Volume 542 of Methods in Enzymology continues the legacy of this premier serial with quality chapters authored by leaders in the field. This new volume covers research methods providing a theoretical overview on metabolic alterations of cancer cells and a series of protocols that can be employed to study oncometabolism, in vitro, ex vivo and in vivo. Malignant cells exhibit metabolic changes when compared to their normal counterparts, owing to both genetic and epigenetic alterations. Although such a metabolic rewiring has recently been indicated as "yet another" general hallmark of cancer, accumulating evidence suggests that the metabolic alterations of each neoplasm rather represent a molecular signature that intimately accompanies, and hence cannot be severed from, all facets of malignant transformation.

Summary : Exposure to particles in industry and mining and from accidental anthropogenic sources constitutes an ongoing threat. Most recently nanoparticles arising from advances in technology are exposing a wider population to pathogenic stimuli. The effects of inhaled particles are no longer confined to the lung as nanoparticles have the potential to translocate to the bloodstream, the brain, and other target sites. The new questions posed by nanoparticles underscore the importance of interdisciplinary research and exchange and highlight the need for new collaborations among disciplines in medicine, toxicology, chemistry, and material sciences. Particle Toxicology brings together the state of the science in particle physico-chemistry, cell biology, and toxicology in a single volume. While organized around the classical toxicology paradigm of exposure - dose - response, the book is unique in its emphasis on mechanistic toxicology. Preparing the reader with a brief historical overview and a conceptual framework for particle research, the book provides reviews on the mechanisms and properties of pathogenic particles and their effects on target cells at various sites in the body. The text describes how adverse effects are a consequence of deposition, translocation, and the complex issue of “dose” dominates. Contributions from leading researchers address particle-associated pro-inflammatory effects and inflammatory signaling, cellular and extracellular oxidative and nitrosative stress, particulate interactions in the pulmonary, cardiovascular, and central nervous systems, as well as genotoxic effects. Exemplar particles include quartz, asbestos, particulate material and nanoparticles. The book also covers mathematical modeling and human studies as avenues for future research. Responding to the evolving trend of consumer applications for particulate matter, Particle Toxicology provides the comprehensive resource for current knowledge from which to develop new concepts to understanding particle actions, measurement, testing, and pathogenic exposure to fine and ultrafine particles.

Summary : Interest in the role of extracellular vesicles (microvesicles and exosomes) is expanding rapidly. It is now apparent that far from being merely cellular debris, these vesicles play a key role in cell-to-cell communication and signaling. Moreover, they are significantly elevated in a number of diseases. This raises the question of their direct role in pathogenesis as well as their possible use as biomarkers. This book stems from the first international meeting on "Microvesicles and Nanovesicles in Health and Disease" held at Magdalen College, Oxford, in 2010. The purpose of the meeting was to bring together, for the first time, a range of experts from around the world to discuss the latest advances in this field. Key to the study of these vesicles is the availability of methodologies for their measurement in biological fluids. A major section of the meeting focused on a range of exciting new technologies which have been developed for this purpose. The presentations at this meeting form the basis of this book, which will appeal to basic scientists, clinicians, and those developing technology for the measurement of extracellular vesicles.

Summary : Apoptosis is an essential biochemical process in cell turnover, development, and chemical-induced cell death. Current knowledge and ongoing research of apoptosis highlight our understanding in designing the therapeutic approaches for several diseases. This book covers four main sections: "Apoptosis and Necrosis," "Apoptosis Inducers," "Proteasome and Signaling Pathways in Apoptosis," and "Radiation-Based Apoptosis." The first section implicitly describes the differences between apoptosis and necrosis processes. The following section elaborates the small molecule-induced apoptosis. Then, the third section deals with proteasome and signaling pathways and finally, resistance to chemotherapy and electromagnetic radiation is covered in the last section. Overall, the book deals with pathways for manipulating apoptosis and provides a unique perspective to the scientists.

Summary : Recent years have witnessed an avalanche of new knowledge implicating free radicals in virtually every aspect of biology and medicine. It is now axiomatic that the regulated accumulation of reactive oxygen species (ROS) contributes to organismal health and well-being and that ROS serve as signaling molecules involved in cell growth, differentiation, gene regulation, replicative senescence and apoptosis. This book is an interdisciplinary text broken up into three consecutive volumes on the biochemistry and cellular/molecular biology of free radicals, transition metals, oxidants and antioxidants, and the role of oxidative stress in human health and disease.

Summary : The Endoplasmic Reticulum (ER) is an organelle with extraordinary signaling and homeostatic functions. It is the organelle responsible for protein folding, maturation, quality control and trafficking of proteins destined for the plasma membrane or for secretion into the extracellular environment. Failure, overloading or malfunctioning of any of the signaling or quality control mechanisms occurring in the ER may provoke a stress condition known as ‘ER stress’. Accumulating evidence indicates that ER stress may dramatically perturb interactions between the cell and its environment, and contribute to the development of human diseases, ranging from metabolic diseases and cancer to neurodegenerative diseases, or impact therapeutic outcome. This book primarily focuses on the pathophysiology of ER stress. It introduces the molecular bases of ER stress, the emerging relevance of the ER-mitochondria cross-talk, the signaling pathways engaged and cellular responses to ER stress, including the adaptive Unfolded Protein Response (UPR), autophagy as well as cell death. Next the book addresses the role of ER stress in physiology and in the etiology of relevant pathological conditions, like carcinogenesis and inflammation, neurodegeneration and metabolic disease. The last chapter describes how ER stress pathways can be targeted for therapeutic benefit. Altogether, this book will provide the reader with an exhaustive view of ER stress biology and the latest insights in the role of ER stress in relevant human diseases.
