Mintz, Kai‐Wen Huang, Piotr Swiderski, Ling Peng, Cheng Liu, Xiaoxuan Liu, Steen Lindkær‐Jensen, Dimitris Zacharoulis, Nikolaos Kostomitsopoulos, Noriyuki Kasahara, Joanna P. Nicholls, Long R. Jiao, Madhava Pai, Duncan R. Spalding, Malkhaz Mizandari, Tinatin Chikovani, Mohamed M. Emara, Abdelali Haoudi, Donald A. Tomalia, John J. Rossi, Nagy A. Habib – 8 August 2013 – Hepatocellular carcinoma (HCC) occurs predominantly in patients with liver cirrhosis.

Maelstrom promotes hepatocellular carcinoma metastasis by inducing epithelial‐mesenchymal transition by way of Akt/GSK‐3β/Snail signaling

Lulu Liu, Yongdong Dai, Jinna Chen, Tingting Zeng, Yan Li, Leilei Chen, Ying‐Hui Zhu, Jiangchao Li, Yan Li, Stephanie Ma, Dan Xie, Yun‐Fei Yuan, Xin‐Yuan Guan – 8 August 2013 – Amplification of 1q is one of the most frequent chromosomal alterations in human hepatocellular carcinoma (HCC). In this study we identified and characterized a novel oncogene, Maelstrom (MAEL), at 1q24. Amplification and overexpression of MAEL was frequently detected in HCCs and significantly associated with HCC recurrence (P = 0.031) and poor outcome (P = 0.001).

Antismooth muscle and antiactin antibodies are indirect markers of histological and biochemical activity of autoimmune hepatitis

Claudia A. Couto, Paulo L. Bittencourt, Gilda Porta, Clarice P. Abrantes‐Lemos, Flair J. Carrilho, Bianca D. Guardia, Eduardo L.R. Cançado – 8 August 2013 – Reactivity and titers of autoantibodies vary during the course of autoimmune hepatitis (AIH), and some autoantibodies have been associated with disease activity and adverse outcomes after treatment. The aim of this study was to assess the autoantibody behavior in AIH and its significance as predictors of biochemical and histological remission.

Mesenchymal stem cells alleviate bacteria‐induced liver injury in mice by inducing regulatory dendritic cells

Yi Zhang, Wei Cai, Qingrong Huang, Yuting Gu, Yufang Shi, Jiefang Huang, Fang Zhao, Qiang Liu, Xunbin Wei, Min Jin, Changping Wu, Qing Xie, Yi Zhang, Bing Wan, Yanyun Zhang – 8 August 2013 – Fulminant hepatic failure (FHF) is a clinical syndrome characterized by sudden and severe impairment of liver function. Mesenchymal stem cells (MSCs) have been proposed as a promising therapeutic approach for FHF. In this study we used Propionibacterium acnes (P. acnes)‐primed, lipopolysaccharide (LPS)‐induced liver injury in mice as an animal model of human FHF.

Serum B‐type natriuretic peptide in the initial workup of patients with new onset ascites: A diagnostic accuracy study

Alberto Q. Farias, Odilson M. Silvestre, Guadalupe Garcia‐Tsao, Luis F.B. Seguro, Daniel F. Mazo, Fernando Bacal, José L. Andrade, Luciana L. Gonçalves, Célia Strunz, Danusa S. Ramos, Demerson Polli, Vincenzo Pugliese, Ana C.T. Rodrigues, Meive S. Furtado, Flair J. Carrilho, Luiz A.C. D'Albuquerque – 2 August 2013 – Heart failure (HF) is, after cirrhosis, the second‐most common cause of ascites. Serum B‐type natriuretic peptide (BNP) plays an important role in the diagnosis of HF. Therefore, we hypothesized that BNP would be useful in the differential diagnosis of ascites.

Differential migration of passenger leukocytes and rapid deletion of naive alloreactive CD8 T cells after mouse liver transplantation

Szun S. Tay, Bo Lu, Fred Sierro, Volker Benseler, Claire M. McGuffog, G. Alex Bishop, Peter J. Cowan, Geoffrey W. McCaughan, Karen M. Dwyer, David G. Bowen, Patrick Bertolino – 2 August 2013 – Donor passenger leukocytes (PLs) from transplanted livers migrate to recipient lymphoid tissues, where they are thought to induce the deletion of donor‐specific T cells and tolerance.

The effects of female sex, viral genotype, and IL28B genotype on spontaneous clearance of acute hepatitis C virus infection

Jason Grebely, Kimberly Page, Rachel Sacks‐Davis, Maarten Schim Loeff, Thomas M. Rice, Julie Bruneau, Meghan D. Morris, Behzad Hajarizadeh, Janaki Amin, Andrea L. Cox, Arthur Y. Kim, Barbara H. McGovern, Janke Schinkel, Jacob George, Naglaa H. Shoukry, Georg M. Lauer, Lisa Maher, Andrew R. Lloyd, Margaret Hellard, Gregory J. Dore, Maria Prins, the InC3 Study Group – 2 August 2013 – Although 20%‐40% of persons with acute hepatitis C virus (HCV) infection demonstrate spontaneous clearance, the time course and factors associated with clearance remain poorly understood.
