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.

Entecavir and Peginterferon Alfa‐2a in Adults With Hepatitis B e Antigen–Positive Immune‐Tolerant Chronic Hepatitis B Virus Infection

Jordan J. Feld, Norah A. Terrault, Hsing‐Hua S. Lin, Steven H. Belle, Raymond T. Chung, Naoky Tsai, Mandana Khalili, Robert Perrillo, Stewart L. Cooper, Marc G. Ghany, Harry L.A. Janssen, Anna S. Lok, for the Hepatitis B Research Network – 14 December 2018 – Monotherapy with interferon or nucleoside analog is generally not recommended during the immune‐tolerant (IT) phase of chronic hepatitis B virus (HBV) infection. Recognition that high HBV DNA levels are associated with hepatocellular carcinoma has increased interest in treating HBV in the IT phase.

p53 Up‐regulated Modulator of Apoptosis Induction Mediates Acetaminophen‐Induced Necrosis and Liver Injury in Mice

Dongshi Chen, Hong‐Min Ni, Lei Wang, Xiaowen Ma, Jian Yu, Wen‐Xing Ding, Lin Zhang – 14 December 2018 – Acetaminophen (APAP) overdose is one of the leading causes of hepatotoxicity and acute liver failure in the United States. Accumulating evidence suggests that hepatocyte necrosis plays a critical role in APAP‐induced liver injury (AILI). However, the mechanisms of APAP‐induced necrosis and liver injury are not fully understood.
