Lymphoid neogenesis and immune infiltration in aged liver

Pallavi Singh, Zeynep Z. Coskun, Catriona Goode, Adam Dean, LuAnn Thompson‐Snipes, Gretchen Darlington – 21 January 2008 – Immune dysregulation and inflammation play a major role in the pathology of age‐related disorders. In an earlier study, the microarray data from our laboratory indicated an increase in inflammation‐related gene expression in the liver with age. We further investigated immune‐related changes in the aged liver and found that the levels of inflammatory cytokines, chemokines, and inflammatory genes were higher in aged animals.

Esophageal capsule endoscopy for screening and surveillance of esophageal varices in patients with portal hypertension

Roberto de Franchis, Glenn M. Eisen, Loren Laine, Inaki Fernandez‐Urien, Juan Manuel Herrerias, Russell D. Brown, Laurel Fisher, Hugo E. Vargas, John Vargo, Julie Thompson, Rami Eliakim – 21 January 2008 – Bleeding from esophageal varices (EV) is a serious consequence of portal hypertension. Current guidelines recommend screening patients with cirrhosis with esophagogastroduodenoscopy (EGD) to detect varices. However, the unpleasantness and need for sedation of EGD may limit adherence to screening programs.

Mechanisms of hepatocyte growth factor–mediated and epidermal growth factor–mediated signaling in transdifferentiation of rat hepatocytes to biliary epithelium

Pallavi B. Limaye, William C. Bowen, Anne V. Orr, Jianhua Luo, George C. Tseng, George K. Michalopoulos – 21 January 2008 – Previous studies from our laboratory have demonstrated that hepatocytes can transdifferentiate into biliary epithelium (BE) both in vivo and in vitro; however, the mechanisms are unclear. The current study was designed to investigate the mechanisms of hepatocyte transdifferentiation in vitro.

Retracted: Outcome and immune reconstitution of HBV‐specific immunity in patients with reactivation of occult HBV infection after alemtuzumab‐containing chemotherapy regimen

Chee‐Kin Hui, Winnie W. Cheung, Kar‐Wai Leung, Vincent C. C. Cheng, Bone S. F. Tang, Iris W. S. Li, John M. Luk, Nikki P. Lee, Yok‐Lam Kwong, Wing‐Yan Au, Kwok‐Yung Yuen, George K. Lau, Raymond Liang – 14 January 2008 – Retraction: The following article from HEPATOLOGY, “Outcome and immune reconstitution of HBV‐specific immunity in patients with reactivation of occult HBV infection after alemtuzumab‐containing chemotherapy regiment” by Chee‐Kin Hui, Winnie W. Cheung, Kar‐Wai Leung, Vincent C. C. Cheng, Bone S. F. Tang, Iris W. S. Li, John M. Luk, Nikki P.

TIS21 negatively regulates hepatocarcinogenesis by disruption of cyclin B1–Forkhead box M1 regulation loop

Tae Jun Park, Ji Yeon Kim, S. Paul Oh, So Young Kang, Bong Wan Kim, Hee Jung Wang, Kye Yong Song, Hyoung Chin Kim, In Kyoung Lim – 14 January 2008 – A functional and biochemical interaction of TIS21/BTG2/PC3 with Forkhead box M1 (FoxM1), essential transcription factor for hepatocyte regeneration and a master regulator of mitotic gene expression, was explored.

Suppressor of cytokine signaling 1 protects mice against concanavalin A–induced hepatitis by inhibiting apoptosis

Takehiro Torisu, Mako Nakaya, Satoko Watanabe, Masayuki Hashimoto, Hideyuki Yoshida, Takatoshi Chinen, Ryoko Yoshida, Fuyuki Okamoto, Toshikatsu Hanada, Kumiko Torisu, Giichi Takaesu, Takashi Kobayashi, Hideo Yasukawa, Akihiko Yoshimura – 14 January 2008 – Acute liver failure is associated with significant mortality. However, the underlying pathophysiological mechanism is not yet fully understood. Suppressor of cytokine signaling‐1 (SOCS1), which is a negative‐feedback molecule for cytokine signaling, has been shown to be rapidly induced during liver injury.

Recombinant factor VIIa for variceal bleeding in patients with advanced cirrhosis: A randomized, controlled trial

Jaime Bosch, Dominique Thabut, Agustín Albillos, Nicolas Carbonell, Julius Spicak, Julien Massard, Gennaro D'Amico, Didier Lebrec, Roberto de Franchis, Søren Fabricius, Yan Cai, Flemming Bendtsen – 14 January 2008 – A beneficial effect of recombinant activated factor VII (rFVIIa) in Child‐Pugh class B and C patients with cirrhosis who have variceal bleeding has been suggested. This randomized controlled trial assessed the efficacy and safety of rFVIIa in patients with advanced cirrhosis and active variceal bleeding.

Ribavirin exposure after the first dose is predictive of sustained virological response in chronic hepatitis C

Véronique Loustaud‐Ratti, Sophie Alain, Annick Rousseau, Isabelle Fouchard Hubert, François Ludovic Sauvage, Pierre Marquet, François Denis, Françoise Lunel, Paul Calès, Annie Lefebvre, Anne‐Laure Fauchais, Eric Liozon, Elisabeth Vidal – 14 January 2008 – The impact of ribavirin exposure on sustained virological response (SVR) in patients with chronic hepatitis C is unknown.

Acetylsalicylic acid inhibits hepatitis C virus RNA and protein expression through cyclooxygenase 2 signaling pathways

Karina Trujillo‐Murillo, Ana Rosa Rincón‐Sánchez, Herminia Martínez‐Rodríguez, Francisco Bosques‐Padilla, Javier Ramos‐Jiménez, Hugo A. Barrera‐Saldaña, Marcos Rojkind, Ana María Rivas‐Estilla – 14 January 2008 – It has been reported that salicylates (sodium salicylate and aspirin) inhibit the replication of flaviviruses, such as Japanese encephalitis virus and dengue virus. Therefore, we considered it important to test whether acetylsalicylic acid (ASA) had anti–hepatitis C virus (HCV) activity.
