Xiaoyong Zhang, Ejuan Zhang, Zhiyong Ma, Rongjuan Pei, Min Jiang, Joerg F. Schlaak, Michael Roggendorf, Mengji Lu – 14 February 2011 – MicroRNAs (miRNAs) are highly conserved small noncoding RNAs participating in regulation of various cellular processes. Viruses have been shown to utilize cellular miRNAs to increase their replication in host cells. Until now, the role of miRNAs in hepatitis B virus (HBV) replication has remained largely unknown. In this study, a number of miRNA mimics were transfected into hepatoma cell lines with HBV replication.

Eric Gershwin, Koichi Akashi – 14 February 2011 – Primary biliary cirrhosis (PBC) is characterized by chronic nonsuppurative destructive cholangitis (CNSDC) associated with destruction of small bile ducts.

James Fung, Ching‐Lung Lai, John Yuen, Charles Cheng, Ringo Wu, Danny Ka‐Ho Wong, Wai‐Kay Seto, Ivan Fan‐Ngai Hung, Man‐Fung Yuen – 14 February 2011 – We aimed to determine the 2‐year outcomes of entecavir followed by lamivudine in patients with undetectable viral load (<12 IU/mL) and normal alanine aminotransferase (ALT) after initial entecavir treatment for at least 6 months. Patients were randomly assigned 1:1 to continue with entecavir or switch to lamivudine. Liver biochemistry and hepatitis B virus (HBV) DNA were determined at weeks 0, 4, 12, 24, 48, 72, and 96.

Tsutomu Matsubara, Naoki Tanaka, Andrew D. Patterson, Joo‐Youn Cho, Kristopher W. Krausz, Frank J. Gonzalez – 14 February 2011 – Lithocholic acid (LCA) is an endogenous compound associated with hepatic toxicity during cholestasis. LCA exposure in mice resulted in decreased serum lysophosphatidylcholine (LPC) and sphingomyelin levels due to elevated lysophosphatidylcholine acyltransferase (LPCAT) and sphingomyelin phosphodiesterase (SMPD) expression.

Nichols, Christof von Kalle, Marinee K. L. Chuah, Maria Grazia Roncarolo, Manfred Schmidt, Thierry VandenDriessche, Luigi Naldini – 11 February 2011 – Lentiviral vectors are attractive tools for liver‐directed gene therapy because of their capacity for stable gene expression and the lack of preexisting immunity in most human subjects.

Manmeet S. Padda, Mayra Sanchez, Abbasi J. Akhtar, James L. Boyer – 11 February 2011 – Recent progress in understanding the molecular mechanisms of bile formation and cholestasis have led to new insights into the pathogenesis of drug‐induced cholestasis. This review summarizes their variable clinical presentations, examines the role of transport proteins in hepatic drug clearance and toxicity, and addresses the increasing importance of genetic determinants, as well as practical aspects of diagnosis and management.
