Sanguineous normothermic machine perfusion improves hemodynamics and biliary epithelial regeneration in donation after cardiac death porcine livers

Qiang Liu, Ahmed Nassar, Kevin Farias, Laura Buccini, William Baldwin, Martin Mangino, Ana Bennett, Colin O'Rourke, Toshiro Okamoto, Teresa Diago Uso, John Fung, Kareem Abu‐Elmagd, Charles Miller, Cristiano Quintini – 8 May 2014 – The effects of normothermic machine perfusion (NMP) on the postreperfusion hemodynamics and extrahepatic biliary duct histology of donation after cardiac death (DCD) livers after transplantation have not been addressed thoroughly and represent the objective of this study.

Prosurvival function of the cellular apoptosis susceptibility/importin‐α1 transport cycle is repressed by p53 in liver cancer

Juliane Winkler, Alessandro Ori, Kerstin Holzer, Carsten Sticht, Daniel Dauch, Eva Maria Eiteneuer, Federico Pinna, Robert Geffers, Volker Ehemann, Amparo Andres‐Pons, Kai Breuhahn, Thomas Longerich, Justo Lorenzo Bermejo, Norbert Gretz, Lars Zender, Peter Schirmacher, Martin Beck, Stephan Singer – 6 May 2014 – Proteins of the karyopherin superfamily including importins and exportins represent an essential part of the nucleocytoplasmic transport machinery. However, the functional relevance and regulation of karyopherins in hepatocellular carcinoma (HCC) is poorly understood.

Elevated sensitivity of macrosteatotic hepatocytes to hypoxia/reoxygenation stress is reversed by a novel defatting protocol

Nir I. Nativ, Gabriel Yarmush, Ashley So, Jeffery Barminko, Timothy J. Maguire, Rene Schloss, Francois Berthiaume, Martin L. Yarmush – 6 May 2014 – Macrosteatotic livers exhibit elevated intrahepatic triglyceride (TG) levels in the form of large lipid droplets (LDs), reduced adenosine triphosphate (ATP) levels, and elevated reactive oxygen species (ROS) levels, and this contributes to their elevated sensitivity to ischemia/reperfusion injury during transplantation. Reducing macrosteatosis in living donors through dieting has been shown to improve transplant outcomes.

Human drug‐induced liver injury severity is highly associated with dual inhibition of liver mitochondrial function and bile salt export pump

Michael D. Aleo, Yi Luo, Rachel Swiss, Paul D. Bonin, David M. Potter, Yvonne Will – 6 May 2014 – Drug‐induced liver injury (DILI) accounts for 20‐40% of all instances of clinical hepatic failure and is a common reason for withdrawal of an approved drug or discontinuation of a potentially new drug from clinical/nonclinical development. Numerous individual risk factors contribute to the susceptibility to human DILI and its severity that are either compound‐ and/or patient‐specific.

However, the functional relevance and regulation of karyopherins in hepatocellular carcinoma (HCC) is poorly understood.

Alpha‐fetoprotein level > 1000 ng/mL as an exclusion criterion for liver transplantation in patients with hepatocellular carcinoma meeting the Milan criteria

Bilal Hameed, Neil Mehta, Gonzalo Sapisochin, John P. Roberts, Francis Y. Yao – 6 May 2014 – Serum alpha‐fetoprotein (AFP) has been increasingly recognized as a marker for a poor prognosis after liver transplantation (LT) for hepatocellular carcinoma (HCC). Many published reports, however, have included a large proportion of patients with HCC beyond the Milan criteria, and the effects of incorporating AFP as an exclusion criterion for LT remain unclear.

Expansion of prominin‐1‐expressing cells in association with fibrosis of biliary atresia

Nirmala Mavila, David James, Pranavkumar Shivakumar, Marie V. Nguyen, Sarah Utley, Katrina Mak, Allison Wu, Shengmei Zhou, Larry Wang, Christopher Vendyres, Megan Groff, Kinji Asahina, Kasper S. Wang – 3 May 2014 – Biliary atresia (BA), the most common cause of end‐stage liver disease and the leading indication for pediatric liver transplantation, is associated with intrahepatic ductular reactions within regions of rapidly expanding periportal biliary fibrosis.

Time to transplantation as a predictor of hepatocellular carcinoma recurrence after liver transplantation

Mariya L. Samoylova, Jennifer L. Dodge, Francis Y. Yao, John Paul Roberts – 3 May 2014 – In the United States, there are significant geographic disparities in the time to transplantation for patients with hepatocellular carcinoma (HCC); it is possible that rapid transplantation contributes to higher rates of posttransplant HCC recurrence because there is insufficient time for the tumor biology to manifest. In this study, we compared HCC recurrence in rapid transplant patients and their slower transplant counterparts.
