Book Description
Methods in Toxicology, Volume 2: Mitochondrial Dysfunction provides a source of methods, techniques, and experimental approaches for studying the role of abnormal mitochondrial function in cell injury. The book discusses the methods for the preparation and basic functional assessment of mitochondria from liver, kidney, muscle, and brain; the methods for assessing mitochondrial dysfunction in vivo and in intact organs; and the structural aspects of mitochondrial dysfunction are addressed. The text also describes chemical detoxification and metabolism as well as specific metabolic reactions that are especially important targets or indicators of damage. The methods for measurement of alterations in fatty acid and phospholipid metabolism and for the analysis and manipulation of oxidative injury and antioxidant systems are also considered. The book further tackles additional methods on mitochondrial energetics and transport processes; approaches for assessing impaired function of mitochondria; and genetic and developmental aspects of mitochondrial disease and toxicology. The text also looks into mitochondrial DNA synthesis, covalent binding to mitochondrial DNA, DNA repair, and mitochondrial dysfunction in the context of developing individuals and cellular differentiation. Microbiologists, toxicologists, biochemists, and molecular pharmacologists will find the book invaluable.

Book Description
Alcoholic liver disease (ALD) continues to be one of the major public health problems in the United States and worldwide. Complicated by factors including gender, polymorphisms of alcohol-metabolizing enzymes, immunologic factors, exposures to other substances/drugs, hepatic viral infections, nutritional deficiencies, and obesity, ALD is a complex disease that requires a systematic approach to dissect the mechanisms associated with organ dysfunction. Mechanistic knowledge is necessary to shed light on routes that potentially may lead to effective treatments. Proteomics as a discovery tool that may reveal new targets and pathways that can potentially be exploited for developing new preventive strategies and treatments. The mitochondrion is the pivotal organelle linked to disease progression and to the development of ALD. Studies have shown links between mitochondrial dysfunction and ethanol-induced liver injury, but the underlying mechanisms at the molecular level still remain largely unknown. In the present study we evaluated the capability of two label-free mass-spectrometry-driven approaches (i) the intensity-based MS[superscript E] method, and (ii) a spectral counting-based method that uses data-dependent acquisition (DDA). Initially a single- and a three-protein model system were utilized to evaluate differences in the performance characteristics of the two methods. To examine the performance difference of the two methods for proteome characterization, we measured changes in protein levels as a consequence of chronic alcohol consumption in rat liver mitochondria. Our results revealed that the MS[superscript E] approach had better performance in terms of precision, and dynamic range and resulted in superior accuracy for fold change determinations. The MS[superscript E] approach proved to identify more mitochondrial proteins than the two DDA methods. However, the run-to-run reproducibility of the MS[superscript E] method was lower than was observed for the DDA methods. Despite poor linear correlation between approaches, the outcomes of the proteome characterizations were rather consistent as more than half of the significantly altered proteins detected by the MS[superscript E] method were also revealed by at least one of the DDA methods. Collectively, we concluded that both MSE and DDA approaches provide satisfactory performance with the MS[superscript E] approach outperforming the DDA-based methods with respect to accuracy, linearity and dynamic range. Further, we integrated the label-free LC-MS[superscript E] quantification with bioinformatics and knowledge base to profile alteration of the mitochondrial proteome for unraveling the protective effect of MitoQ, a mitochondrial targeted ubiquinone, on ALD. With carefully maintained stability of the LC-MS system, robust proteome datasets with high technical precision were obtained. By taking advantage of the information-rich quantitative proteomic data, we quantitatively categorized the identified proteins and performed pathway analysis for each category independently. Metabolic pathways and associated proteins were highlighted with the guidance of the systems biology approach. In summary, our results indicated that the pathways enriched in response to MitoQ included acyl-CoA synthases and the carnitine shuttle, ketogenesis, the TCA cycle and oxidative phosphorylation. The MitoQ-responsive metabolic network suggested that MitoQ up-regulates fatty acid transportation to counteract accumulation of lipids in the fatty liver. For dissecting the mitochondrial proteome, we develop a "targeted" quantitative approach involving label-free mass spectrometry-based quantification, chemoselective labeling, avidin- biotin based affinity enrichment at both protein and peptide level. The approach was applied to mitochondria exposed to 4-hydroxy-2-nonenal (HNE) for depicting a subset of the mitochondrial proteome susceptible to HNE insult. The utilization of the carbonyl-selective probe, ARP, facilitated labeling of HNE-adducted proteins and enabled avidin affinity enrichment with the biotin moiety. A list of potential protein targets with concentration-dependent response and known HNE modification sites was obtained when combining results from the protein- and peptide-level enrichment workflows. The core list of putative protein targets of HNE adduction may serve as lead for further validation studies towards unraveling the pathogenesis of ALD and emerging treatment modalities using Western blotting or targeted LC-MS methods.

Book Description
Mitochondria are subcellular organelles evolved by the endosymbiosis of bacteria with eukaryotic cells. They are the main source of ATP in the cell and engaged in other aspects of cell metabolism and cell function, including the regulation of ion homeostasis, cell growth, redox status, and cell signaling. Due to their central role in cell life and death, mitochondria are also involved in the pathogenesis and progression of human diseases/conditions, including neurodegenerative and cardiovascular disorders, cancer, diabetes, inflammation, and aging. However, despite the increasing number of studies, precise mechanisms whereby mitochondria are involved in the regulation of basic physiological functions, as well as their role in the cell under pathophysiological conditions, remain unknown. A lack of in-depth knowledge of the regulatory mechanisms of mitochondrial metabolism and function, as well as interplay between the factors that transform the organelle from its role in pro-survival to pro-death, have hindered the development of new mitochondria-targeted pharmacological and conditional approaches for the treatment of human diseases. This book highlights the latest achievements in elucidating the role of mitochondria under physiological conditions, in various cell/animal models of human diseases, and in patients.

Book Description
The topic of alcohol and the liver is long overdue for re-evaluation. The authors of this book have clearly taken up this challenge. Human interest in alcohol dates back to the Neolithic period (circa 10,000 BC). Only a small amount of alcohol is found naturally in food. Therefore, humans have yet to adapt to the high quantities of alcohol consumed daily by alcohol abusers. Alcohol is a simple carbohydrate and is metabolised as a fuel. However, unlike more naturally occurring carbohydrates such as glucose, the pathways for its metabolism are not subject to the same checks and balances. Ethanol oxidation reduces NAD+, which starves reactions that depend on this substrate. This accounts for the accumulation of fat in alcoholic steatosis. Alcohol metabolism generates significant amounts of reactive oxygen species (ROS), which damages mtDNA and subsequently mitochondrial integrity. The authors provide several lines of evidence that link the clinical picture of alcoholic liver disease with mitochondrial damage. Other important topics highlighted in this book include histo-pathological aspects of the disease. Clinical assessment of nutrition and vitamin supplementation is addressed as well. The book concludes with the highly topical and controversial aspect of liver transplantation in patients with alcoholic liver disease.
