Download or read book Repression of HNF4A Enables Transcriptomic Reprogramming During the Hepatic Acute phase Response written by Charlotte Ehle and published by . This book was released on 2024* with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hepatic acute-phase response is characterized by a massive upregulation of serum proteins, such as haptoglobin and serum amyloid A, at the expense of liver homeostatic functions. Although the transcription factor hepatocyte nuclear factor 4 alpha (HNF4A) has a well-established role in safeguarding liver function and its cistrome spans around 50% of liver-specific genes, its role in the acute-phase response has received little attention so far. We demonstrate that HNF4A binds to and represses acute-phase genes under basal conditions. The reprogramming of hepatic transcription during inflammation necessitates loss of HNF4A function to allow expression of acute-phase genes while liver homeostatic genes are repressed. In a pre-clinical liver organoid model overexpression of HNF4A maintained liver functionality in spite of inflammation-induced cell damage. Conversely, HNF4A overexpression potently impaired the acute-phase response by retaining chromatin at regulatory regions of acute-phase genes inaccessible to transcription. Taken together, our data extend the understanding of dual HNF4A action as transcriptional activator and repressor, establishing HNF4A as gatekeeper for the hepatic acute-phase response.

Download or read book Nuclear Receptors written by Chris M. Bunce and published by Springer Science & Business Media. This book was released on 2010-03-11 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1890 a case of myxedema was treated in Lisbon by the implantation of a sheep thyroid gland with the immediate improvement in the patient’s condition. A few years later, medications for the then ill-explained condition of the menopause included tablets made from cow ovaries. In the first quarter of the 20th century the identification of vitamin D, and its sunlight driven production in skin, paved the way to the elimination of rickets as a major medical problem. Twenty years or so later, Sir Vincent Wigglesworth established the endocrine basis of developmental moulting in insects, arguably the most commonly performed animal behaviour on Planet Earth. A paradigm that would unify these disparate observations arose between 1985 and 1987 beginning with the identification of the glucocorticoid receptor and the nuclear receptor super-family. What follows is a timely and positive manifestation of the capacity, productivity and value of international human scientific endeavour. Based on intrigue, lively competition and cooperation a global effort has rapidly fostered a school of biology with widespread ramifications for the understanding of metazoan animals, the human condition and the state of the planet. This book is the first this century to try and capture the spirit of this endeavour, to depict where the field is now and to identify some of the challenges and opportunities for the future.

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.

Download or read book Vitamin D Receptor Regulation of Cholesterol 7 alpha hydroxylase Gene Transcription and Bile Acid Synthesis in Human Hepatocytes written by Shuxin Han and published by . This book was released on 2009 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vitamin D receptor (VDR) plays an important role in the regulation of calcium and phosphate homeostasis and bone formation. Lithocholic acid (LCA) is a potent endogenous ligand of VDR. In cholestasis, LCA levels increase in the liver and intestine. The objective of this study is to test the hypothesis that VDR plays a role in inhibiting the gene expression of cholesterol 7[alpha]-hydroxylase (CYP7A1) and bile acid synthesis in human hepatocytes. Immunoblot analysis has detected VDR proteins in the human hepatoma cell line HepG2 and primary hepatocytes. 1[alpha], 25-dihydroxy-vitamin D3 (1[alpha], 25(OH)2-VD3) or LCA acetate-activated VDR inhibited CYP7A1 mRNA expression and bile acid synthesis, whereas small interfering RNA (siRNA) to VDR completely abrogated VDR inhibition of CYP7A1 in HepG2 cells. LCA or 1[alpha], 25(OH)2-VD3 induced VDR translocation from the cytosol to the nucleus and plasma membrane in human primary hepatocytes. LCA or 1[alpha], 25(OH)2-VD3 activated a tyrosine kinase c-Src and the VDR signaling pathway, which activated c-Raf, an upstream kinase of the MAPK pathway. Kinase inhibition and in vitro kinase assays showed that VDR specifically activated extracellular signal-regulated kinase 1/2 (ERK1/2), which phosphorylated VDR, retinoid X receptor [alpha] (RXR[alpha]) and hepatocyte nuclear factor 4[alpha] (HNF4[alpha]). Mammalian two-hybrid, coimmunoprecipitation, glutathione S-transferase pull-down, and chromatin immunoprecipitation assays show that ligand activated VDR specifically interacts with HNF4[alpha] to block HNF4[alpha] interaction with coactivators. ERK1/2 inhibitors suppressed VDR interaction with HNF4[alpha]. Electrophoretic mobility shift assay and mutagenesis analyses have identified the negative VDR response elements that bind VDR/RXR[alpha] in the human CYP7A1 promoter. Chromatin immunoprecipitation assays show that LCA or 1[alpha], 25(OH)2-VD3 activated ERK1/2 stimulated the recruitment of VDR, RXR[alpha] and co-repressors, but decreased the occupancy of HNF4[alpha] and coactivators to human CYP7A1 chromatin, resulting in the inhibition of CYP7A1 gene transcription. In conclusion, LCA and 1[alpha], 25(OH)2-VD3 caused intracellular translocation of VDR to the plasma membrane and nucleus in human hepatocytes. LCA and VDR activated the c-Raf/MEK/ERK1/2 pathway to regulate VDR inhibition of CYP7A1 in hepatocytes. This study identified a novel bile acid-activated VDR signaling pathway in human hepatocytes. LCA activation of VDR may inhibit bile acid synthesis and protect hepatocytes from cholestatic liver injury.
