Intestine‐Specific Overexpression of Carboxylesterase 2c Protects Mice From Diet‐Induced Liver Steatosis and Obesity

Lisa Katharina Maresch, Pia Benedikt, Ursula Feiler, Sandra Eder, Kathrin A. Zierler, Ulrike Taschler, Stephanie Kolleritsch, Thomas O. Eichmann, Gabriele Schoiswohl, Christina Leopold, Beatrix I. Wieser, Caroline Lackner, Thomas Rülicke, Jan van Klinken, Dagmar Kratky, Tarek Moustafa, Gerald Hoefler, Guenter Haemmerle – 17 December 2018 – Murine hepatic carboxylesterase 2c (Ces2c) and the presumed human ortholog carboxylesterase 2 (CES2) have been implicated in the development of nonalcoholic fatty liver disease (NAFLD) in mice and obese humans.

Modulation of Insulin Resistance in Nonalcoholic Fatty Liver Disease

Reenam S. Khan, Fernando Bril, Kenneth Cusi, Philip N. Newsome – 16 December 2018 – Nonalcoholic fatty liver disease (NAFLD) has an estimated prevalence of 25% in the general population, and cirrhosis secondary to nonalcoholic steatohepatitis (NASH) is predicted to become the leading cause of liver transplantation, yet there is a lack of effective licensed treatments for these conditions. There is a close relationship between insulin resistance (IR) and NAFLD, with prevalence of NAFLD being 5‐fold higher in patients with diabetes compared to those without.

Sirtuin 4 Depletion Promotes Hepatocellular Carcinoma Tumorigenesis Through Regulating Adenosine‐Monophosphate–Activated Protein Kinase Alpha/Mammalian Target of Rapamycin Axis in Mice

Yun‐Shan Wang, Lutao Du, Xingsi Liang, Peng Meng, Lei Bi, Yu‐li Wang, Chuanxin Wang, Bo Tang – 15 December 2018 – Sirtuin 4 (SIRT4) has been reported to play a vital role in the maintenance of glutamine catabolism and adenosine triphosphate (ATP) homeostasis, but its character in hepatocellular carcinomas (HCCs) remains obscure. In this study, we observed low expression of SIRT4 in both HCC cell lines and HCCs from patients. Decreased disease‐free survival time is associated with low tumor levels of SIRT4 in patients.

Recurrence of Hereditary Hemorrhagic Telangiectasia After Liver Transplantation: Clinical Implications and Physiopathological Insights

Jérôme Dumortier, Sophie Dupuis‐Girod, Pierre‐Jean Valette, Alexander Valent, Olivier Guillaud, Jean‐Christophe Saurin, Valérie Hervieu, Philip Robinson, Henri Plauchu, Pierre Paliard, Olivier Boillot, Jean‐Yves Scoazec – 14 December 2018 – Liver transplantation (LT) has been proposed as a curative treatment in hereditary hemorrhagic telangiectasia (HHT) with severe hepatic involvement. We provide a long‐term evaluation of graft status after LT for HHT, with a focus on the risk of recurrence.
