Download or read book Targeting Mitochondrial Pathways in Obesity and Type 2 Diabetes written by Jessica Erin Sacks and published by . This book was released on 2018 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obesity is one of the largest medical epidemics our society faces today. There are over forty obesity-associated diseases that affect nearly every organ system in the body, including Type 2 Diabetes (T2D) and Non-Alcoholic Fatty Liver Disease (NAFLD). Insulin resistance is one of the hallmark characteristics underlying metabolic diseases, and mitochondrial dysfunction is believed to be a central player in this phenomenon, yet our understanding of the specific molecular mechanisms that serve as cause and consequence of defective mitochondria remain complex and elusive despite significant attention. In the studies presented in this dissertation, liver tissue isolated from a rat model of obesity-induced NAFLD and human subject-derived skeletal muscle cells revealed two distinct mechanisms by which mitochondrial dynamics may play a key role in regulating the progression of insulin resistance and cellular bioenergetics in obesity-related metabolic diseases. First, we found that markers of mitochondrial fusion and biogenesis are upregulated in the liver of obese Sprague-Dawley rats following gastric bypass surgery, and expression of a specific fusion marker, namely mitofusin 1, is associated with reductions in body weight and improved insulin sensitivity. Utilizing human primary skeletal muscle cells isolated from percutaneous needle biopsy, we found that metformin treatment in vitro upregulates glycolytic pathways, suppresses mitochondrial respiration, and activates a specific protein of mitochondrial fission. Together, the work presented here describes mitochondrial mechanisms related to insulin resistance in two obesity models and major metabolic tissues.

Download or read book Disordered Skeletal Muscle Oxidative Metabolism In Human Obesity and Type 2 Diabetes written by Ghadi Antoun and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Obesity and type 2 diabetes mellitus (T2DM) are both complex diseases with multifactorial etiologies. Together they affect over 640 million people worldwide and have a significant impact on the global healthcare system incurring costs of over 800 billion dollars. The overall goal of my doctoral research has been to elucidate metabolic predictors and underlying mechanisms in obesity and T2DM. Specifically, I have examined mechanisms contributing to disordered oxidative metabolism in skeletal muscle. My research included participants who were recruited from the Ottawa Hospital Weight Management Clinic in which they completed a clinically supervised meal-replacement and lifestyle intervention program. More so, my doctoral studies evaluated characteristics of muscle mitochondrial function in obesity and T2DM and revealed impaired mitochondrial respiration and electron transport chain supercomplex assembly in muscle from patients with T2DM. The first aim was to study the impact of T2DM on weight loss ability in a large population of obese patients participating in a standardized meal replacement and lifestyle modification program. As there is considerable variability in weight loss propensity, it was found that T2DM significantly deters weight loss although the effect is not large. Since skeletal muscle energetics are central in the development and progression of obesity and T2DM, the second and third aims were to study mitochondrial function in this tissue with the idea of uncovering molecular etiologies. The second aim found deficiencies in mitochondrial respiration in individuals with obesity and T2DM compared to individuals with obesity alone. Reductions in mitochondrial respiration were correlated with increasing levels of HbA1C and attributed to paucity in supercomplex formation in the mitochondrial inner membrane (MIM) of the electron transport chain (ETC). The third aim was to delineate differential fuel oxidation mechanisms and circulating protein biomarkers in obese diet-sensitive (ODS) and obese diet-resistant (ODR) participants following a high fat meal (HFM) challenge. Whole-body analyses were conducted in addition to measures in blood, adipose tissue, skeletal muscle and primary cells. Remarkable increases in oxidative capacity were measured post-HFM. In addition, impaired mitochondrial function was found in the ODR group despite lack of differences in mitochondrial content or the assembly of supercomplexes. Differences were also found in circulating acylcarnitines as well as expression of several proteins including Heat shock 70 kDa protein 1A/1B, Tyrosine-protein kinase Fgr, and Peptidyl-prolyl cis-trans isomerase D. Ultimately, a better understanding of mechanisms involved could lead to significant improvements in personalized medical approaches in obesity and T2DM.

Download or read book Advances in Mitochondrial Medicine written by Roberto Scatena and published by Springer Science & Business Media. This book was released on 2012-03-08 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitochondria are far more than the “powerhouse” of the cell as they have classically been described. In fact, mitochondria biological activities have progressively expanded to include not only various bioenergetic processes but also important biosynthetic pathways, calcium homeostasis and thermogenesis, cell death by apoptosis, several different signal transduction pathways mainly related to redox control of gene expression and so on. This functional and structural complexity may undergo important derangements so to justify the definition of ‘mitochondrial medicine’, which should include all the clinical consequences of congenital or acquired mitochondrial dysfunctions. There are actually a growing number of studies which assign a significant pathogenic role to damaged mitochondria in different diseases: ischemia/reperfusion injury, neurodegenerative diseases, cancer with its dramatic sequelae (i.e, metastasis), metabolic syndrome, hyperlipidemias, just to mention a few of the most important pathologies. In this context, a further aspect that should not be disregarded is the interaction of pharmacological agents with mitochondria, not only in regard of the toxicological aspects but, above all, of the potential therapeutic applications. In fact, it is interesting to note that, while the properties of different so-called “mitoxicants” are well-known, the subtle linkages between drugs and mitochondria is still in need of a real pharmacological and therapeutic control at the clinical level. This lack of consideration can often lead to an underestimation of unwanted toxic effects but also of desirable therapeutic activities. A reevaluation of the potential clinical role of mitochondria could give a new light on some yet obscure aspects of human pathophysiology.

Download or read book Organelle Contact Sites written by Mitsuo Tagaya and published by Springer. This book was released on 2017-08-16 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first comprehensive coverage of the quickly evolving research field of membrane contact sites (MCS). A total of 16 chapters explain their organization and role and unveil the significance of MCS for various diseases. MCS, the intracellular structures where organellar membranes come in close contact with one another, mediate the exchange of proteins, lipids, and ions. Via these functions, MCS are critical for the survival and the growth of the cell. Owing to that central role in the functioning of cells, MCS dysfunctions lead to important defects of human physiology, influence viral and bacterial infection, and cause disease such as inflammation, type II diabetes, neurodegenerative disorders, and cancer. To approach such a multifaceted topic, this volume assembles a series of chapters dealing with the full array of research about MCS and their respective roles for diseases. Most chapters also introduce the history and the state of the art of MCS research, which will initiate discussion points for the respective types of MCS for years to come. This work will appeal to all cell biologists as well as researchers on diseases that are impacted by MCS dysfunction. Additionally, it will stimulate graduate students and postdocs who will energize, drive, and develop the research field in the near future.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
