Toshinobu Kawabata, Manabu Kinoshita, Akihito Inatsu, Yoshiko Habu, Hiroyuki Nakashima, Nariyoshi Shinomiya, Shuhji Seki – 28 October 2008 – Immune functions of liver natural killer T (NKT) cells induced by the synthetic ligand α‐galactosylceramide enhanced age‐dependently; hepatic injury and multiorgan dysfunction syndrome (MODS) induced by ligand‐activated NKT cells were also enhanced. This study investigated how aging affects liver innate immunity after common bacteria DNA stimulation.

Zhaowen Zhu, Anne T. Wilson, M. Meleah Mathahs, Feng Wen, Kyle E. Brown, Bruce A. Luxon, Warren N. Schmidt – 28 October 2008 – Oxidative injury to hepatocytes occurs as a result of hepatitis C virus (HCV) infection and replication. Modulation of host cell antioxidant enzymes such as heme oxygenase‐1 (HO‐1) may be useful therapeutically to minimize cellular injury, reduce viral replication, and attenuate liver disease. In this report, we evaluated the effects of HO‐1 overexpression on HCV replication and hepatocellular injury.

Rodica Gincul, Gaetan Lesca, Bénédicte Gelas‐Dore, Nathalie Rollin, Martine Barthelet, Sophie Dupuis‐Girod, Franck Pilleul, Sophie Giraud, Henri Plauchu, Jean‐Christophe Saurin – 28 October 2008 – Hereditary hemorrhagic telangiectasia (HHT) is a genetic disease characterized by cutaneous, mucosal, and sometimes visceral arteriovenous malformations. Severe hepatic manifestations have been characterized in a subgroup of patients, but few data are available in previously nonscreened patients. We prospectively evaluated liver involvement and its cardiac consequences in such patients.

Archimandritis – 28 October 2008 – The diagnosis of hepatitis B e antigen (HBeAg)‐negative chronic hepatitis B indicating therapeutic intervention currently requires serum hepatitis B virus (HBV) DNA ≥2,000 IU/mL.

Wenjiao Zeng, Annette S.H. Gouw, Marius C. van den Heuvel, Peter J. Zwiers, Pieter E. Zondervan, Sibrand Poppema, Nong Zhang, Inge Platteel, Koert P. de Jong, Grietje Molema – 28 October 2008 – Quantitative data on the expression of multiple factors that control angiogenesis in hepatocellular carcinoma (HCC) are limited. A better understanding of the mechanisms underlying angiogenesis in HCC will improve the rational choice of anti‐angiogenic treatment.

Christopher M. Schonhoff, Krishna Thankey, Cynthia R.L. Webster, Yoshiyuki Wakabayashi, Allan W. Wolkoff, M. Sawkat Anwer – 28 October 2008 – Cyclic adenosine monophosphate (cAMP) stimulates hepatic bile acid uptake by translocating sodium‐taurocholate (TC) cotransporting polypeptide (Ntcp) from an endosomal compartment to the plasma membrane. Rab4 is associated with early endosomes and involved in vesicular trafficking. This study was designed to determine the role of Rab4 in cAMP‐induced TC uptake and Ntcp translocation.

Akira Uchiyama, Jae‐Sung Kim, Kazuyoshi Kon, Hartmut Jaeschke, Kenichi Ikejima, Sumio Watanabe, John J. Lemasters – 28 October 2008 – Iron overload exacerbates various liver diseases. In hepatocytes, a portion of non‐heme iron is sequestered in lysosomes and endosomes. The precise mechanisms by which lysosomal iron participates in hepatocellular injury remain uncertain. Here, our aim was to determine the role of intracellular movement of chelatable iron in oxidative stress‐induced killing to cultured hepatocytes from C3Heb mice and Sprague‐Dawley rats.

Keun‐Gyu Park, Ae‐Kyung Min, Eun Hee Koh, Hyoun Sik Kim, Mi‐Ok Kim, Hye‐Sun Park, Yong‐Deuk Kim, Tae‐Seung Yoon, Byoung Kuk Jang, Jae Seok Hwang, Jae Bum Kim, Hueng‐Sik Choi, Joong‐Yeol Park, In‐Kyu Lee, Ki‐Up Lee – 28 October 2008 – Fatty liver is common in obese subjects with insulin resistance. Hepatic expression of sterol regulatory element binding protein‐1c (SREBP‐1c), which plays a major role in hepatic steatosis, is regulated by multiple factors, including insulin, adenosine monophosphate–activated protein kinase (AMPK), liver X receptors (LXRs), and specificity protein 1.

Marija Zeremski, Lydia M. Petrovic, Luis Chiriboga, Queenie B. Brown, Herman T. Yee, Milan Kinkhabwala, Ira M. Jacobson, Rositsa Dimova, Marianthi Markatou, Andrew H. Talal – 28 October 2008 – Chemokines, chemotactic cytokines, may promote hepatic inflammation in chronic hepatitis C virus (HCV) infection through the recruitment of lymphocytes to the liver parenchyma.

Chuan Yin, Yong Lin, Xin Zhang, Yue‐Xiang Chen, Xin Zeng, Hai‐Yan Yue, Jun‐Liang Hou, Xing Deng, Jun‐Ping Zhang, Ze‐Guang Han, Wei‐Fen Xie – 28 October 2008 – Previous studies have shown that hepatocyte nuclear factor‐4α (HNF4α) is a central regulator of differentiated hepatocyte phenotype and forced expression of HNF4α could promote reversion of tumors toward a less invasive phenotype. However, the effect of HNF4α on cancer stem cells (CSCs) and the treatment of hepatocellular carcinoma (HCC) with HNF4α have not been reported.
