Novel function of Niemann‐Pick C1‐like 1 as a negative regulator of Niemann‐Pick C2 protein

Yoshihide Yamanashi, Tappei Takada, Jun‐Ichi Shoda, Hiroshi Suzuki – 16 November 2011 – The hepatic expression of Niemann‐Pick C1‐like 1 (NPC1L1), which is a key molecule in intestinal cholesterol absorption, is high in humans. In addition to NPC1L1, Niemann‐Pick C2 (NPC2), a secretory cholesterol‐binding protein involved in intracellular cholesterol trafficking and the stimulation of biliary cholesterol secretion, is also expressed in the liver. In this study, we examined the molecular interaction and functional association between NPC1L1 and NPC2.

Albumin infusion in patients undergoing large‐volume paracentesis: A meta‐analysis of randomized trials

Mauro Bernardi, Paolo Caraceni, Roberta J. Navickis, Mahlon M. Wilkes – 16 November 2011 – Albumin infusion reduces the incidence of postparacentesis circulatory dysfunction among patients with cirrhosis and tense ascites, as compared with no treatment. Treatment alternatives to albumin, such as artificial colloids and vasoconstrictors, have been widely investigated. The aim of this meta‐analysis was to determine whether morbidity and mortality differ between patients receiving albumin versus alternative treatments.

Rapid generation of mature hepatocyte‐like cells from human induced pluripotent stem cells by an efficient three‐step protocol

Yu‐Fan Chen, Chien‐Yu Tseng, Hsei‐Wei Wang, Hung‐Chih Kuo, Vincent W. Yang, Oscar K. Lee – 16 November 2011 – Liver transplantation is the only definitive treatment for end‐stage cirrhosis and fulminant liver failure, but the lack of available donor livers is a major obstacle to liver transplantation. Recently, induced pluripotent stem cells (iPSCs) derived from the reprogramming of somatic fibroblasts, have been shown to resemble embryonic stem (ES) cells in that they have pluripotent properties and the potential to differentiate into all cell lineages in vitro, including hepatocytes.

Glucokinase links Krüppel‐like factor 6 to the regulation of hepatic insulin sensitivity in nonalcoholic fatty liver disease

Efficient human fetal liver cell isolation protocol based on vascular perfusion for liver cell–based therapy and case report on cell transplantation

Bruno Gridelli, Giovanni Vizzini, Giada Pietrosi, Angelo Luca, Marco Spada, Salvatore Gruttadauria, Davide Cintorino, Giandomenico Amico, Cinzia Chinnici, Toshio Miki, Eva Schmelzer, Pier Giulio Conaldi, Fabio Triolo, Jörg C. Gerlach – 27 October 2011 – Although hepatic cell transplantation (CT) holds the promise of bridging patients with end‐stage chronic liver failure to whole liver transplantation, suitable cell populations are under debate.
