Karen F. Murray, Leszek Szenborn, Jacek Wysocki, Stephen Rossi, Amoreena C. Corsa, Phillip Dinh, John McHutchison, Phillip S. Pang, Luminita M. Luminos, Malgorzata Pawlowska, Jacek Mizerski – 27 April 2012 – Tenofovir disoproxil fumarate (DF) is highly effective for the suppression of hepatitis B virus (HBV) in chronically infected adults. This study evaluated the safety and efficacy of tenofovir DF in adolescents with chronic hepatitis B (CHB).

Erica L. Clinkenbeard, James E. Butler, Brett T. Spear – 27 April 2012 – We previously showed that mouse alpha‐fetoprotein (AFP) enhancer 3 activity is highly restricted to pericentral hepatocytes in the adult liver. Here, using transgenic mice, we show that the upstream enhancer of the rat glutamine synthetase gene is also active, specifically in pericentral regions. Activity of both enhancers is lost in the absence of β‐catenin, a key regulator of zonal gene expression in the adult liver.

Friedman, Won‐Il Jeong – 27 April 2012 – Clinical trials and animal models suggest that infusion of bone marrow cells (BMCs) is effective therapy for liver fibrosis, but the underlying mechanisms are obscure, especially those associated with early effects of BMCs. Here, we analyzed the early impact of BMC infusion and identified the subsets of BMCs showing antifibrotic effects in mice with carbon tetrachloride–induced liver fibrosis.

Ho, See Ching Chan, Sheung Tat Fan – 27 April 2012 – Liver transplantation (LT) is a cure for many liver diseases. Blood chimerism of donor origin can develop after LT, which raises the possibility of the existence of hematopoietic stem/progenitor cells (HSPCs) in the liver. We characterized the blood chimerism in a large cohort of 249 LT patients and analyzed putative HSPCs in adult human livers.

Guzman, Michael P. Manns, Michael Ott, Michael Bock – 26 April 2012 – Macrophages play an important role in the rejection of xenogeneic cells and therefore represent a major obstacle to generating chimeric mice with human xenografts that are useful tools for basic and preclinical medical research.
