Available in PDF, EPUB and Kindle. Book excerpt: The liver is an exceptionally complex and diverse organ that functions both as an exocrine and an endocrine gland. It secretes bile, which contains many con stituents in addition to bile salts, and it synthesizes and releases many substances in response to the body's demands, including prohormones, albumin, clotting factors, glucose, fatty acids, and various lipoproteins. It has a dual blood supply providing a rich mixture of nutrients and other absorbed substances via the portal vein and oxygen-rich blood via the hepatic artery. This functional heterogeneity is accompanied by cellular heterogeneity. The liver contains many cell types including hepatic parachymal cells, Kiipffer cells, Ito cells, and endothelial cells. The most abundant cell type, the parenchymal cells, are biochemically and structurally heterogeneous. The cells in the oxygen-rich areas of the portal triad appear more dependent on oxidative metabolism, whereas those around the central vein (pericentral, perivenous, or centrolobular areas) are more dependent upon an anaerobic mechanism. Throughout this volume the latter three terms are used synonymously by various authors to indicate the five to eight layers of cells radiating from the central vein. Structural and metabolic heterogeneity of hepatic parenchymal cells has been demonstrated by a variety of approaches, including histochemical, ultra structural, and ultramicrobiochemical studies. This microheterogeneity is linked to the physiological functions of the liver and its response to injurious substances.

Download or read book Hepatic De Novo Lipogenesis and Regulation of Metabolism written by James M. Ntambi and published by Springer. This book was released on 2015-12-17 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The liver is the largest solid vital organ in mammals that supports other organ in the body in some facet. This book synthesizes all the primary and relevant metabolic information that one needs to review to understand the complex and diverse role of the liver in metabolism. With the current epidemic of metabolic diseases, it is of immediate importance to understand the contribution of the liver in health and its role in the development of impaired metabolic regulation. This book covers the many studies that have unmasked important roles that proteins expressed in the liver play in the development of or protection from metabolic diseases. One of the major metabolic functions of the liver is to carry out de novo lipogenesis, which is the metabolic pathway that allows the conversion of excess carbohydrates into fatty acids. The process of de novo lipogenesis is covered in depth within this volume. The book is an important contribution to the vast literature and ongoing research on liver function.
Download or read book Regulation of Hepatic Metabolism Through PGC 1 alpha mediated Pathways written by Linda Grasfeder and published by . This book was released on 2007 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: PGC-1alpha is a transcriptional coactivator selectively expressed in tissues with high metabolic demands and induced by a variety of metabolic stressors, including cold, exercise, and fasting. When expressed, PGC-1alpha can coactivate a number of transcription factors to coordinately activate metabolic pathways that supply tissues and the body with necessary nutrients. PGC-1alpha has emerged as a master controller of mitochondria and many of the processes focused within them, including oxidative phosphorylation, fatty acid oxidation, the TCA cycle and free radical scavenging. PGC-1alpha also induces gluconeogenesis and expression of glucose transporters, thereby regulating blood glucose levels. Given this integral role in modulating energy homeostasis, understanding how PGC-1alpha functions and what factors regulate its activity could help identify processes and proteins that malfunction in various metabolic disorders.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Liver is a key regulator of systemic metabolism in physiology and pathology. It maintains cholesterol, triglyceride and glucose homeostasis in response to fasting and feeding. Transcription factors responsive to hormones and nutrients coordinate many of these responses. They regulate gene networks relating to lipid, glucose and amino acid metabolism during fasting and feeding, and factors such as sex, circadian rhythms and dietary content interact with these transcriptional programs, as reviewed in chapter 1. Understanding the different players in these processes and how they interact with each other will be key to develop strategies to combat metabolic diseases. Recent advances in probing the transcriptional landscape, coupled with high throughput sequencing approaches such as assay for transposase accessible chromatin (ATAC-Seq), have enabled the identification of transcriptional regulators of these processes and their interrelationships. In chapter 2, I describe results from a screen using ATAC-Seq and RNA-Seq to profile novel transcriptional regulators of the hepatic response to fasting and feeding. We determined GATA4 expression and activity to be upregulated by feeding through insulin. Knocking out Gata4 in adult liver impaired the transcriptional and metabolic response to feeding. Additionally, loss of hepatic GATA4 led to a reduction in HDL cholesterol and to the accumulation of liver triglycerides. These effects were accompanied by the downregulation of genes involved in cholesterol efflux and triglyceride hydrolysis, and the upregulation of genes involved in lipid uptake. Furthermore, hepatic GATA4 colocalized and collaborated with Liver X Receptor (LXR), a key regulator of cholesterol transport. In chapter 3, I investigated the dynamics of hepatic LXRs via ATAC-Seq and RNA-Seq in wild-type and LXR[alpha]/[Beta] knockout liver. Loss of LXRs in liver changed the transcriptional regulatory landscape by reducing accessibility at enhancers and increasing accessibility at promoters. A broad set of transcription factors that bind enhancers, including nuclear receptors, had reduced activity based on their motif accessibility, showing their reliance on LXRs. Moreover, this investigation demonstrated that LXR also functions as a transcriptional repressor of certain genes. Overall, these studies revealed important functions for GATA4 and LXR within hepatic transcriptional networks, extending our understanding of transcriptional regulation of hepatic lipid metabolism.
