Nicolas Plumb‐Rudewiez, Frédéric Clotman, Hélène Strick‐Marchand, Christophe E. Pierreux, Mary C. Weiss, Guy G. Rousseau, Frédéric P. Lemaigre – 24 November 2004 – A network of liver‐enriched transcription factors controls differentiation and morphogenesis of the liver. These factors interact via direct, feedback, and autoregulatory loops. Previous work has suggested that hepatocyte nuclear factor (HNF)‐6/OC‐1 and HNF‐3α/FoxA1 participate coordinately in this hepatic network. We investigated how HNF‐6 controls the expression of Foxa1.

Ming‐Chin Yu, Cheng‐Hsu Chen, Xiaoyan Liang, Lianfu Wang, Chandrashekhar R. Gandhi, John J. Fung, Lina Lu, Shiguang Qian – 24 November 2004 – In the injured liver, hepatic stellate cells (HSCs) secrete many different cytokines, recruit lymphocytes, and thus participate actively in the pathogenesis of liver disease. Little is known of the role of HSCs in immune responses. In this study, HSCs isolated from C57BL/10 (H2b) mice were found to express scant key surface molecules in the quiescent stage.

Fifty patients with severe, histologically proven alcoholic hepatitis were enrolled.

Jeffrey D. Browning, Lidia S. Szczepaniak, Robert Dobbins, Pamela Nuremberg, Jay D. Horton, Jonathan C. Cohen, Scott M. Grundy, Helen H. Hobbs – 24 November 2004 – Despite the increasing prevalence of nonalcoholic fatty liver disease (NAFLD), its pathogenesis and clinical significance remain poorly defined. In this study, we examined and compared the distribution of hepatic triglyceride content (HTGC) in 2,287 subjects from a multiethnic, population‐based sample (32.1% white, 48.3% black, and 17.5% Hispanic) using proton magnetic resonance spectroscopy.

Isao Sakaida, Shuji Terai, Naoki Yamamoto, Koji Aoyama, Tsuyoshi Ishikawa, Hiroshi Nishina, Kiwamu Okita – 24 November 2004 – We investigated the effect of bone marrow cell (BMC) transplantation on established liver fibrosis. BMCs of green fluorescent protein (GFP) mice were transplanted into 4‐week carbon tetrachloride (CCl4)–treated C57BL6 mice through the tail vein, and the mice were treated for 4 more weeks with CCl4 (total, 8 weeks).

Vincent Di Martino, Pascal Lebray, Robert P. Myers, Emmanuelle Pannier, Valérie Paradis, Frédéric Charlotte, Joseph Moussalli, Dominique Thabut, Catherine Buffet, Thierry Poynard – 24 November 2004 – Female sex is a protective factor for the progression of fibrosis in patients with chronic hepatitis C virus (HCV) infection. Experimental data suggest that estrogens may have an antifibrotic effect.

Martti Färkkilä, Anna‐Liisa Karvonen, Heimo Nurmi, Hannu Nuutinen, Matti Taavitsainen, Pekka Pikkarainen, Päivi Kärkkäinen – 24 November 2004 – No effective medical therapy is currently available for primary sclerosing cholangitis (PSC). Ursodeoxycholic acid (UDCA) improves liver enzymes, but its effect on liver histology is controversial. Metronidazole (MTZ) prevents PSC‐like liver damage in animal models and reduces intestinal permeability.
