Characterization of ferroptosis in murine models of hemochromatosis

Hao Wang, Peng An, Enjun Xie, Qian Wu, Xuexian Fang, Hong Gao, Zhuzhen Zhang, Yuzhu Li, Xudong Wang, Jiaying Zhang, Guoli Li, Lei Yang, Wei Liu, Junxia Min, Fudi Wang – 13 February 2017 – Ferroptosis is a recently identified iron‐dependent form of nonapoptotic cell death implicated in brain, kidney, and heart pathology. However, the biological roles of iron and iron metabolism in ferroptosis remain poorly understood. Here, we studied the functional role of iron and iron metabolism in the pathogenesis of ferroptosis.

Galectin‐9: Diverse roles in hepatic immune homeostasis and inflammation

Lucy Golden‐Mason, Hugo R. Rosen – 13 February 2017 – Glycan‐binding proteins, which include galectins, are involved at all stages of immunity and inflammation, from initiation through resolution. Galectin‐9 (Gal‐9) is highly expressed in the liver and has a wide variety of biological functions in innate and adaptive immunity that are instrumental in the maintenance of hepatic homeostasis. In the setting of viral hepatitis, increased expression of Gal‐9 drives the expansion of regulatory T cells and contraction of effector T cells, thereby favoring viral persistence.

Liver fibrosis scores predict liver disease mortality in the United States population

Aynur Unalp‐Arida, Constance E. Ruhl – 13 February 2017 – Fatty liver disease is common in the United States and worldwide due to changing lifestyles and can progress to fibrosis and cirrhosis contributing to premature death. We examined whether liver fibrosis scores were associated with increased overall and disease‐specific mortality in a United States population–based prospective survey with up to 23 years of linked‐mortality data. Data were analyzed from 14,841 viral hepatitis–negative adult participants in the third National Health and Nutrition Examination Survey, 1988‐1994.

RIG‐I is a key antiviral interferon‐stimulated gene against hepatitis E virus regardless of interferon production

Lei Xu, Wenshi Wang, Yunlong Li, Xinying Zhou, Yuebang Yin, Yijin Wang, Robert A. de Man, Luc J.W. van der Laan, Fen Huang, Nassim Kamar, Maikel P. Peppelenbosch, Qiuwei Pan – 13 February 2017 – Interferons (IFNs) are broad antiviral cytokines that exert their function by inducing the transcription of hundreds of IFN‐stimulated genes (ISGs). However, little is known about the antiviral potential of these cellular effectors on hepatitis E virus (HEV) infection, the leading cause of acute hepatitis globally.

Human immunodeficiency virus–infected liver transplant recipients with incidental hepatocellular carcinoma: A prospective multicenter nationwide cohort study

Fernando Agüero, Alejandro Forner, Andrés Valdivieso, Marino Blanes, Rafael Barcena, Christian Manzardo, Antoni Rafecas, Lluis Castells, Manuel Abradelo, Pilar Barrera‐Baena, Luisa González‐Diéguez, Magdalena Salcedo, Trinidad Serrano, Miguel Jiménez‐Pérez, José Ignacio Herrero, Mikel Gastaca, Victoria Aguilera, Juan Fabregat, Santos del Campo, Itxarone Bilbao, Carlos Jiménez Romero, Asunción Moreno, Antoni Rimola, José M.

Beneficial and harmful effects of nonselective beta blockade on acute kidney injury in liver transplant candidates

Sang Gyune Kim, Joseph J. Larson, Ji Sung Lee, Terry M. Therneau, W. Ray Kim – 10 February 2017 – Nonselective beta‐blockers (NSBBs) have played an important role in the prevention of portal hypertensive bleeding in patients with cirrhosis. However, recent studies have suggested that NSBBs may be harmful in some patients with end‐stage liver disease. The purpose of this article is to evaluate the association between use of NSBB and the incidence of acute kidney injury (AKI). We conducted a nested case‐control study in a cohort of liver transplant wait‐list registrants.

Recurrence of hepatocellular carcinoma after liver transplantation: Is there a place for resection?

Elena Fernandez‐Sevilla, Marc‐Antoine Allard, Jasmijn Selten, Nicolas Golse, Eric Vibert, Antonio Sa Cunha, Daniel Cherqui, Denis Castaing, René Adam – 10 February 2017 – Recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) is widely considered as a terminal condition. Therefore, the role of surgery is uncertain in this case. The purpose of this study was to identify the prognostic factors of survival after post‐LT HCC recurrence and to evaluate the impact of surgery in this setting.

Exogenous vascular endothelial growth factor delivery prior to endothelial precursor cell transplantation in orthotopic liver transplantation–induced hepatic ischemia/reperfusion injury

Ding Cao, Menghao Wang, Junhua Gong, Sidong Wei, Jianping Gong, Jinzheng Li – 10 February 2017 – Vascular endothelial growth factor (VEGF) promotes angiogenesis in vivo. We hypothesized that exogenous delivery of VEGF prior to bone marrow–derived endothelial precursor cell (EPC) transplantation may improve orthotopic liver transplantation (OLT)–induced hepatic ischemia/reperfusion injury (HIRI).
