Report of the first international liver transplantation society expert panel consensus conference on renal insufficiency in liver transplantation

Michael R. Charlton, William J. Wall, Akinlolu O. Ojo, Pere Ginés, Stephen Textor, Fuad S. Shihab, Paul Marotta, Marcelo Cantarovich, James D. Eason, Russell H. Wiesner, Michael A. Ramsay, Juan C. Garcia‐Valdecasas, James M. Neuberger, Sandy Feng, Connie L. Davis, Thomas A. Gonwa – 28 October 2009

A20 protects mice from lethal liver ischemia/reperfusion injury by increasing peroxisome proliferator‐activated receptor‐α expression

Haley E. Ramsey, Cleide G. Da Silva, Christopher R. Longo, Eva Csizmadia, Peter Studer, Virendra I. Patel, Scott M. Damrauer, Jeffrey J. Siracuse, Soizic Daniel, Christiane Ferran – 28 October 2009 – The nuclear factor‐κB inhibitory protein A20 demonstrates hepatoprotective abilities through combined antiapoptotic, anti‐inflammatory, and pro‐proliferative functions. Accordingly, overexpression of A20 in the liver protects mice from toxic hepatitis and lethal radical hepatectomy, whereas A20 knockout mice die prematurely from unfettered liver inflammation.

Liver graft exposure to carbon monoxide during cold storage protects sinusoidal endothelial cells and ameliorates reperfusion injury in rats

Atsushi Ikeda, Shinya Ueki, Atsunori Nakao, Koji Tomiyama, Mark A. Ross, Donna B. Stolz, David A. Geller, Noriko Murase – 28 October 2009 – Hepatic ischemia/reperfusion (I/R) injury significantly influences short‐term and long‐term outcomes after liver transplantation (LTx). The critical step initiating the injury is known to include sinusoidal endothelial cell (SEC) alteration during the cold preservation period.

Incidence of abdominal wall numbness post–liver transplantation and its complications

Ashokkumar Jain, Pauline Nemitz, Rajeev Sharma, Baber Sheikh, Saman Safadjou, Marry Vetter, Leah Brayan, Pam Batzold, Randeep Kashyap, Mark Orloff – 28 October 2009 – Liver transplantation (LTx) is a life‐saving procedure for end‐stage liver disease. However, LTx remains a major surgical procedure with a significant amount of morbidity and mortality.

Changes in the expression of methionine adenosyltransferase genes and S‐adenosylmethionine homeostasis during hepatic stellate cell activation

Komal Ramani, Heping Yang, John Kuhlenkamp, Lauda Tomasi, Hidekazu Tsukamoto, José M. Mato, Shelly C. Lu – 27 October 2009 – Hepatic stellate cell (HSC) activation is an essential event during liver fibrogenesis. Methionine adenosyltransferase (MAT) catalyzes biosynthesis of S‐adenosylmethionine (SAMe), the principle methyl donor. SAMe metabolism generates two methylation inhibitors, methylthioadenosine (MTA) and S‐adenosylhomocysteine (SAH).

Insulin‐like growth factor I gene transfer to cirrhotic liver induces fibrolysis and reduces fibrogenesis leading to cirrhosis reversion in rats

Luciano Sobrevals, Carlos Rodriguez, José Lorenzo Romero‐Trevejo, Gabor Gondi, Iñaki Monreal, Astrid Pañeda, Nerea Juanarena, Sara Arcelus, Nerea Razquin, Laura Guembe, Gloria González‐Aseguinolaza, Jesús Prieto, Puri Fortes – 27 October 2009 – We investigated whether gene transfer of insulin‐like growth factor I (IGF‐I) to the hepatic tissue was able to improve liver histology and function in established liver cirrhosis.

Bile salt sequestration induces hepatic de novo lipogenesis through farnesoid X receptor– and liver X receptorα–controlled metabolic pathways in mice

Hilde Herrema, Maxi Meissner, Theo H. van Dijk, Gemma Brufau, Renze Boverhof, Maaike H. Oosterveer, Dirk‐Jan Reijngoud, Michael Müller, Frans Stellaard, Albert K. Groen, Folkert Kuipers – 23 October 2009 – Diabetes is characterized by high blood glucose levels and dyslipidemia. Bile salt sequestration has been found to improve both plasma glycemic control and cholesterol profiles in diabetic patients. Yet bile salt sequestration is also known to affect triglyceride (TG) metabolism, possibly through signaling pathways involving farnesoid X receptor (FXR) and liver X receptor α (LXRα).

Bicarbonate secretion of mouse cholangiocytes involves Na+‐HCO 3− cotransport in addition to Na+‐independent Cl−/HCO3− exchange

Iker Uriarte, Jesús M. Banales, Elena Sáez, Fabián Arenas, Ronald P. J. Oude Elferink, Jesús Prieto, Juan F. Medina – 23 October 2009 – Bicarbonate secretion from cholangiocytes is required for appropriate adjustment of primary canalicular bile along the biliary tract. In human and rat cholangiocytes, bicarbonate secretion is mediated by anion exchanger (AE) 2, an electroneutral Na+‐independent Cl−/HCO 3− AE also involved in intracellular pH (pHi) regulation. In Ae2a,b‐deficient mice, pHi is increased in lymphocytes and fibroblasts, whereas it is surprisingly normal in cholangiocytes.
