This book was released on 2013-08-15 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obesity and diabetes develop as a complex result of genetic, metabolic and environmental factors and are characterized by increased lipogenesis and lipid accumulation in many tissues. Stearoyl-CoA desaturase (SCD) genes are a critical regulator of lipogenesis and catalyzes the synthesis of monounsaturated fatty acids (MUFA), mainly oleoyl- (18:1n9) and palmitoleoyl-CoA (16:1n7). These MUFAs are the major fatty acid substrates for the synthesis of triglycerides, cholesterol esters, wax esters and membrane phospholipids. There are 4 SCD isoforms (SCD1-4) in mice and two (hSCD1 and hSCD5) expressed in humans. At first glance, stearoyl-CoA desaturase enzyme would be considered a housekeeping enzyme because it synthesizes oleate a well-known fatty acid that is abundant in many dietary sources. However numerous studies have shown that SCD is a very highly regulated enzyme that features in so many physiological processes ranging from fat differentiation, carbohydrate and fat metabolism, inflammation and cancer. The editor’s studies using stearoyl-CoA desaturase knockout (SCD1-/-) mice and studies of other investigators using pharmacological approaches to reduce SCD1 expression in mouse tissues have all established that the expression of SCD1 gene isoform represents a key step in partitioning of lipids between storage and oxidation. High SCD expression favors fat storage leading to obesity while reduced SCD expression favors fat burning and leanness. Although these studies clearly illustrated that SCD1 expression is involved in the development of obesity and insulin resistance, questions remain in the elucidation of the mechanisms involved and role of SCD1. This book includes chapters by leading researchers on SCD Genes in the brain, heart, muscle, liver metabolism, Colitis, and more. ​

Available in PDF, EPUB and Kindle. Book excerpt: James Ntambi has gathered top authors to write about the remarkable growth of research on the role of the stearoyl-CoA desaturase (SCD) genes in metabolism in different species including human. The book shows that beginning with simple cellular models of differentiation a broad and comprehensive analysis of the SCD gene family in a number of species and biological systems has been carried out over the course of the last twenty five years. SCD is a central enzyme in lipid metabolism that synthesizes monounsaturated fatty acids (MUFA) from saturated fatty acid precursors. At first glance, SCD would be considered a housekeeping enzyme because its product oleate is a well-known MUFA that is abundant in many dietary sources and tissue lipids. A particular highlight in the chapters of the book is that MUFAs may have signaling properties that regulate metabolism. For example, a proper ratio of saturated to MUFA contributes to membrane fluidity, and oleate has also been implicated as a mediator of signal transduction, cellular differentiation and metabolic homeostasis. It is also highlighted that SCD-1 repression mediates the metabolic effects of the hormone leptin. Conditional alleles and corresponding tissue-specific knockout mouse models for many of the SCD gene isorfms have provided a wealth of information on not only tissue-specific fatty acid metabolism but also the key transcription factors that regulate SCD expression under a variety of metabolic and genetic backgrounds. The studies described indicate that control of SCD expression occurs via a series of complex signal transduction schemes making SCD one of the most highly studied lipogenic gene families to date.

Download or read book Plant Lipid Metabolism written by J.C. Kader and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: A collection of papers that comprehensively describe the major areas of research on lipid metabolism of plants. State-of-the-art knowledge about research on fatty acid and glycerolipid biosynthesis, isoprenoid metabolism, membrane structure and organization, lipid oxidation and degradation, lipids as intracellular and extracellular messengers, lipids and environment, oil seeds and gene technology is reviewed. The different topics covered show that modern tools of plant cellular and molecular biology, as well as molecular genetics, have been recently used to characterize several key enzymes of plant lipid metabolism (in particular, desaturases, thioesterases, fatty acid synthetase) and to isolate corresponding cDNAs and genomic clones, allowing the use of genetic engineering methods to modify the composition of membranes or storage lipids. These findings open fascinating perspectives, both for establishing the roles of lipids in membrane function and intracellular signalling and for adapting the composition of seed oil to the industrial needs. This book will be a good reference source for research scientists, advanced students and industrialists wishing to follow the considerable progress made in recent years on plant lipid metabolism and to envision the new opportunities offered by genetic engineering for the development of novel oil seeds.

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 Lipids in Health and Disease written by Peter Quinn and published by Springer Science & Business Media. This book was released on 2008-08-27 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.
