Available in PDF, EPUB and Kindle. Book excerpt: In this book, the current understanding of the mechanisms of each beta cell toxins are reviewed, reported toxin resistant insulinoma or immortalised beta cells are summarised, and the different nature of those toxin resistant cells are analysed. With advancements in cancer stem cell research, the possible involvement of stem cells enrichment after various toxin challenges is also discussed. Moreover, there is a renewed interest in the study of the function of fatty acid synthase (FASN) and fatty-acid synthesis in cancer pathogenesis. This book outlines the role of FASN in cancer development and the pre-clinical development of FASN inhibitors and their anti-tumour effects. In addition, Parkinson disease (PD) is a neurodegenerative disorder characterised by a progressive loss of the nigrostriatal dopaminergic neurons. The authors discuss the roles of oxidative modification of the proteins of mitochondrial respiration in the pathogenesis of PD. Furthermore, it has been currently understood that the key role in the physiological and regenerative restoration of adult tissues belongs to adult stems cells. Adult stem cell survival after the action ionizing radiation, hyperthermia and in the conditions of the "ischemia/reperfusion" reaction development are examined.

Download or read book Mitochondria and Cancer written by Keshav Singh and published by Springer Science & Business Media. This book was released on 2009-04-05 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly a century of scientific research has revealed that mitochondrial dysfunction is one of the most common and consistent phenotypes of cancer cells. A number of notable differences in the mitochondria of normal and cancer cells have been described. These include differences in mitochondrial metabolic activity, molecular composition of mitochondria and mtDNA sequence, as well as in alteration of nuclear genes encoding mitochondrial proteins. This book, Mitochondria and Cancer, edited by Keshav K. Singh and Leslie C. Costello, presents thorough analyses of mitochondrial dysfunction as one of the hallmarks of cancer, discusses the clinical implications of mitochondrial defects in cancer, and as unique cellular targets for novel and selective anti-cancer therapy.
Download or read book Regulation of Tissue Oxygenation Second Edition written by Roland N. Pittman and published by Biota Publishing. This book was released on 2016-08-18 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Download or read book Metabolic Control in Cell Proliferation and Cell Survival written by Marian H. Harris and published by . This book was released on 2002 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitochondria are known as both producers of cellular ATP and as central regulators of apoptosis. However a functional link between cellular bioenergetics and cell survival has remained controversial. In particular, the ability of Bcl-2 family proteins, established regulators of cell survival, to regulate mitochondrial metabolism has generated much debate. And although metazoan cells are known to be dependent on the presence of extracellular cues for continued survival, the ability of these cues to regulate bioenergetics has not been extensively explored. This thesis addresses the role of glycolytic and mitochondrial metabolism in the control of cell survival. Expression of the pro-apoptotic Bcl-2 family protein, Bax, in the yeast Saccharomyces cerevisiae caused impairment of mitochondrial respiration and cell death. Furthermore, the ability of Bax to initiate cell death was inhibited in yeast unable to perform oxidative phosphorylation. This prompted an investigation of whether Bax inhibits the shift from glycolytic metabolism to oxidative metabolism or initiates apoptotic death in response to such a change. The withdrawal of growth factors or extracellular nutrients from mammalian cells is associated with a decline in glycolysis and increased dependency on oxidative phosphorylation. Under these conditions, Bax becomes activated and translocates to the mitochondria, resulting in cytochrome c release and apoptosis. Cells lacking Bax and its homologue Bak, however, could live for weeks following growth factor withdrawal in a metabolic state dependent on oxidative phosphorylation. Since the metabolic changes following either glucose or growth factor withdrawal were similar, the growth factor IL-3 was investigated as a primary regulator of aerobic glycolysis. As IL-3 availability increased, cells became more glycolytically active and thus less dependent on mitochondrial respiration for ATP production. This metabolic profile is normally associated with cellular transformation, suggesting that constitutive activation of growth factor signaling pathways may underlie the high glycolytic rate and apoptotic resistance of cancer cells.
Download or read book The Heterogeneity of Cancer Metabolism written by Anne Le and published by Springer. This book was released on 2018-06-26 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Mitochondria in Health and Diseases written by Sabzali Javadov and published by . This book was released on 2020-09-04 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Plant Respiration written by Hans Lambers and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Respiration in plants, as in all living organisms, is essential to provide metabolic energy and carbon skeletons for growth and maintenance. As such, respiration is an essential component of a plant’s carbon budget. Depending on species and environmental conditions, it consumes 25-75% of all the carbohydrates produced in photosynthesis – even more at extremely slow growth rates. Respiration in plants can also proceed in a manner that produces neither metabolic energy nor carbon skeletons, but heat. This type of respiration involves the cyanide-resistant, alternative oxidase; it is unique to plants, and resides in the mitochondria. The activity of this alternative pathway can be measured based on a difference in fractionation of oxygen isotopes between the cytochrome and the alternative oxidase. Heat production is important in some flowers to attract pollinators; however, the alternative oxidase also plays a major role in leaves and roots of most plants. A common thread throughout this volume is to link respiration, including alternative oxidase activity, to plant functioning in different environments.

Download or read book Cancer as a Metabolic Disease written by Thomas Seyfried and published by John Wiley & Sons. This book was released on 2012-05-18 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Cellular Respiration and Carcinogenesis written by Shireesh Apte and published by Springer Science & Business Media. This book was released on 2008-12-18 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellular Respiration and Carcinogenesis presents leading experts in the field as it informs the reader about both basic and recent research in the field of cellular respiration and the effects of its dysfunction, alteration or attenuation on the development of cancer. This masterfully compiled text offers the reader a fundamental understanding about how oxygen sensing and/or availability, programmed cell death, immune recognition and response and glucose metabolism are intimately linked with the two major mechanism or pathways of cellular respiration; oxidative phosphorylation and glycolysis. The editors and contributing authors proficiently and unequivocally address the effects of dysfunction of the mitochondrial oxidative phosphorylation/glycolysis (cellular respiration) mechanisms and pathways on the development of cancer. While it remains true that there are no universal truths in cancer, Cellular Respiration and Carcinogenesis opens the dialogue that the etiology of cancer can usually be associated with, and significantly attributed to the failure of one or multiple pathways of oxidative phosphorylation (cellular respiration) to normally burn fuel to generate energy, vis-à-vis the Warburg hypothesis. Keeping with its cutting-edge nature, Cellular Respiration and Carcinogenesis provides the first glimpse to a cautionary evidence based counterbalance to the recent and rapidly proliferating notion that utilization of fuel primarily via glycolysis is a hallmark of cancer development.
