Phosphatidylcholines as regulators of glucose and lipid homeostasis: Promises and potential risks
Simon Hohenester, Ulrich Beuers – 2 December 2011 – Nuclear hormone receptors regulate diverse metabolic pathways and the orphan nuclear receptor LRH‐1 (also known as NR5A2) regulates bile acid biosynthesis. Structural studies have identified phospholipids as potential LRH‐1 ligands, but their functional relevance is unclear. Here we show that an unusual phosphatidyl‐choline species with two saturated 12 carbon fatty acid acyl side chains (dilauroyl phosphatidylcholine (DLPC)) is an LRH‐1 agonist ligand in vitro.
Alteration of hepatic nuclear receptor‐mediated signaling pathways in hepatitis C virus patients with and without a history of alcohol drinking
Chuanghong Wu, Richard Gilroy, Ryan Taylor, Mojtaba Olyaee, Bashar Abdulkarim, Jameson Forster, Maura O'Neil, Ivan Damjanov, Yu‐Jui Yvonne Wan – 2 December 2011 – The current study tests a hypothesis that nuclear receptor signaling is altered in chronic hepatitis C patients and that the altered pattern is specific to alcohol drinking history. The expression of a panel of more than 100 genes encoding nuclear receptors, coregulators, and their direct/indirect targets was studied in human livers.
Serum ferritin concentration and transferrin saturation before liver transplantation predict decreased long‐term recipient survival
Tobias J. Weismüller, Gabriele I. Kirchner, Marcus N. Scherer, Ahmed A. Negm, Andreas A. Schnitzbauer, Frank Lehner, Jürgen Klempnauer, Hans J. Schlitt, Michael P. Manns, Christian P. Strassburg – 2 December 2011 – Serum ferritin (SF) concentration is a widely available parameter used to assess iron homeostasis. It has been described as a marker to identify high‐risk patients awaiting liver transplantation (LT) but is also elevated in systemic immune‐mediated diseases, metabolic syndrome, and in hemodialysis where it is associated with an inferior prognosis.
Multiple ascending dose study of BMS‐790052, a nonstructural protein 5A replication complex inhibitor, in patients infected with hepatitis C virus genotype 1
Richard E. Nettles, Min Gao, Marc Bifano, Ellen Chung, Anna Persson, Thomas C. Marbury, Ronald Goldwater, Michael P. DeMicco, Maribel Rodriguez‐Torres, Apinya Vutikullird, Ernesto Fuentes, Eric Lawitz, Juan Carlos Lopez‐Talavera, Dennis M. Grasela – 2 December 2011 – The antiviral activity, resistance profile, pharmacokinetics (PK), safety, and tolerability of BMS‐790052, a nonstructural protein 5A (NS5A) replication complex inhibitor, were evaluated in a double‐blind, placebo‐controlled, sequential panel, multiple ascending dose study.

Alexandru V. Olaru, Gabriel Ghiaur, Sumitaka Yamanaka, Delgermaa Luvsanjav, Fangmei An, Irinel Popescu, Sorin Alexandrescu, Sarah Allen, Timothy M. Pawlik, Michael Torbenson, Christos Georgiades, Lewis R. Roberts, Gregory J. Gores, Anne Ferguson‐Smith, Maria I. Almeida, George A. Calin, Esteban Mezey, Florin M. Selaru – 2 December 2011 – MicroRNAs (miRs) recently emerged as prominent regulators of cancer processes.
Multipotent stem/progenitor cells in human biliary tree give rise to hepatocytes, cholangiocytes, and pancreatic islets
Vincenzo Cardinale, Yunfang Wang, Guido Carpino, Cai‐Bin Cui, Manuela Gatto, Massimo Rossi, Pasquale Bartolomeo Berloco, Alfredo Cantafora, Eliane Wauthier, Mark E. Furth, Luca Inverardi, Juan Dominguez‐Bendala, Camillo Ricordi, David Gerber, Eugenio Gaudio, Domenico Alvaro, Lola Reid – 2 December 2011 – Multipotent stem/progenitors are present in peribiliary glands of extrahepatic biliary trees from humans of all ages and in high numbers in hepato‐pancreatic common duct, cystic duct, and hilum.

Magnetic resonance imaging of focal liver lesions: Approach to imaging diagnosis
Kathryn J. Fowler, Jeffrey J. Brown, Vamsi R. Narra – 2 December 2011 – This article is a review of magnetic resonance imaging (MRI) of incidental focal liver lesions. This review provides an overview of liver MRI protocol, diffusion‐weighted imaging, and contrast agents. Additionally, the most commonly encountered benign and malignant lesions are discussed with emphasis on imaging appearance and the diagnostic performance of MRI based on a review of the literature.
