Jean‐Charles Nault, Gabrielle Couchy, Stefano Caruso, Léa Meunier, Laure Caruana, Eric Letouzé, Sandra Rebouissou, Valérie Paradis, Julien Calderaro, Jessica Zucman‐Rossi – 24 March 2018 – Genetic alterations define different molecular subclasses of hepatocellular adenoma (HCA) linked with risk factors, histology and clinical behavior. Recently, Argininosuccinate Synthase 1 (ASS1), a major periportal protein, was proposed as a marker of HCA with a high risk of hemorrhage. We aimed to assess the significance of ASS1 expression through the scope of the HCA molecular classification.

Rajib Mukherjee, Maria E. Moreno‐Fernandez, Daniel A. Giles, Monica Cappelletti, Traci E. Stankiewicz, Calvin C. Chan, Senad Divanovic – 24 March 2018 – Nonalcoholic fatty liver disease (NAFLD) represents a disease spectrum ranging from benign steatosis to life‐threatening cirrhosis and hepatocellular carcinoma. Elevated levels of reactive oxygen species (ROS) and exacerbated inflammatory responses have been implicated in NAFLD progression.

Davor Slijepcevic, Reinout L.P. Roscam Abbing, Claudia D. Fuchs, Lizette C.M. Haazen, Ulrich Beuers, Michael Trauner, Ronald P.J. Oude Elferink, Stan F.J. van de Graaf – 24 March 2018 – Accumulation of bile salts (BSs) during cholestasis leads to hepatic and biliary injury, driving inflammatory and fibrotic processes. The Na+‐Taurocholate Cotransporting Polypeptide (NTCP) is the major hepatic uptake transporter of BSs, and can be specifically inhibited by myrcludex B. We hypothesized that inhibition of NTCP dampens cholestatic liver injury.

Yichao Zhao, Fang Wang, Lingchen Gao, Longwei Xu, Renyang Tong, Nan Lin, Yuanyuan Su, Yang Yan, Yu Gao, Jie He, Lingcong Kong, Ancai Yuan, Ying Zhuge, Jun Pu – 23 March 2018 – Nonalcoholic fatty liver disease (NAFLD), characterized by hepatic steatosis (HS), insulin resistance (IR), and inflammation, poses a high risk of cardiometabolic disorders. Ubiquitin specific protease 4 (USP4), a deubiquitinating enzyme, is pivotally involved in regulating multiple inflammatory pathways; however, the role of USP4 in NAFLD is unknown.

Chapman, Annarosa Floreani, David E. Jones, Cristina de Min, David H. Adams, Pietro Invernizzi – 23 March 2018 – NI‐0801 is a fully human monoclonal antibody against chemokine (C‐X‐C motif) ligand 10 (CXCL10), which is involved in the recruitment of inflammatory T cells into the liver. The safety and efficacy of NI‐0801 was assessed in patients with primary biliary cholangitis.

Cynthia Levy, Christopher L. Bowlus, Elizabeth Carey, Julie M. Crawford, Karen Deane, Marlyn J. Mayo, W. Ray Kim, Michael W. Fried – 23 March 2018 – Primary biliary cholangitis (PBC) is a rare chronic cholestatic liver disease that may progress to biliary cirrhosis if left untreated. The first‐line therapy for PBC is ursodeoxycholic acid (UDCA). Unfortunately, 1 of 3 patients does not respond to UDCA. These patients are at risk for developing clinical events, including cirrhosis, complications of portal hypertension, hepatocellular carcinoma, liver transplant, or death. Recently, the U.S.

Keri E. Lunsford, Colin Court, Yong Seok Lee, David S. Lu, Bita V. Naini, Michael P. Harlander‐Locke, Ronald W. Busuttil, Vatche G. Agopian – 23 March 2018 – Mixed hepatocellular‐cholangiocarcinomas (HCC‐CCAs) are rare tumors with both hepatocellular and biliary differentiation. While liver transplantation (LT) is the gold standard treatment for patients with unresectable hepatocellular carcinoma (HCC), it is contraindicated in known HCC‐CCA because of concerns of poor prognosis. We sought to compare posttransplant oncologic outcomes for HCC‐CCA and a matched cohort of HCC LT recipients.

Uprichard, Harel Dahari, Kazuaki Chayama – 23 March 2018 – Chimeric urokinase type plasminogen activator (uPA)/severely severe combined immunodeficiency (SCID) mice reconstituted with humanized livers are useful for studying hepatitis B virus (HBV) infection in the absence of an adaptive immune response.

Benedikt Schaefer, Mattias Mandorfer, André Viveiros, Armin Finkenstedt, Peter Ferenci, Stefan Schneeberger, Herbert Tilg, Heinz Zoller – 23 March 2018 – Alpha‐1‐antitrypsin deficiency (A1ATD) due to homozygosity for the Z allele (ZZ) is an established risk factor for cirrhosis, but the liver disease risk in heterozygous Z allele carriers (MZ) is controversial. The aim of the present study was to determine the prevalence of the MZ genotype among patients with cirrhosis and the associated risk of decompensation and liver transplantation/mortality.
