Zifei Pei, Liang Chu, Weiguo Zou, Zilai Zhang, Songbo Qiu, Rong Qi, Jinfa Gu, Cheng Qian, Xinyuan Liu – 26 April 2004 – Hepatocellular carcinoma (HCC) displays a high resistance to tumor necrosis factor–related apoptosis–inducing ligand (TRAIL)–mediated cell death. To increase sensitivity of HCC cells to TRAIL, we have constructed an oncolytic adenoviral vector (ZD55) and used this vector to deliver second mitochondria‐derived activator of caspases (Smac) and TRAIL genes (ZD55‐Smac and ZD55‐TRAIL, respectively) into HCC cells.

The aim of this study was to evaluate the efficacy of an association of infliximab and prednisolone at reducing the 2‐month mortality rate among patients with severe AAH.

Sanjay B. Jadaho, Rong‐Ze Yang, Qiang Lin, Hong Hu, Frank A. Anania, Alan R. Shuldiner, Da‐Wei Gong – 26 April 2004 – Alanine aminotransferase (ALT) is a widely used index of liver integrity or hepatocellular damage in clinics as well as a key enzyme in intermediatary metabolism. In this study, we have cloned the complementary DNAs of murine homologues of human alanine aminotransferase 1 and 2 (ALT1 and ALT2). The deduced peptides of murine ALT1 (mALT1) and ALT2 (mALT2) share 87% and 93% identity, respectively, with their human counterparts at the amino acid level.

Shuji Matsumura, Judy Van de Water, Patrick Leung, Joseph A. Odin, Kazuhide Yamamoto, Gregory J. Gores, Keith Mostov, Aftab A. Ansari, Ross L. Coppel, Yasushi Shiratori, M. Eric Gershwin – 26 April 2004 – Anti‐mitochondrial antibodies (AMAs) have long been recognized as a serological hallmark of primary biliary cirrhosis (PBC). Although high titers of immunoglobulin (Ig)A AMAs are found in bile, saliva, and urine of patients, a pathogenic role for this antibody has remained elusive.

Alexis Laurent, Carole Nicco, Jeanne Tran Van Nhieu, Didier Borderie, Christiane Chéreau, Filomena Conti, Patrick Jaffray, Olivier Soubrane, Yvon Calmus, Bernard Weill, Frédéric Batteux – 26 April 2004 – Nonalcoholic fatty liver disease, frequently associated with obesity, can lead to nonalcoholic steatohepatitis (NASH) and cirrhosis. The pathophysiology of NASH is poorly understood, and no effective treatment is available. In view of a potential deleterious role for reactive oxygen species (ROS), we investigated the origin of ROS overproduction in NASH.

Qing Liu, Zhong Ping Duan, Da Kang Ha, Stig Bengmark, Jelica Kurtovic, Stephen M. Riordan – 26 April 2004 – Minimal hepatic encephalopathy (MHE) is an important disorder that may seriously impair daily functioning and quality of life in patients with cirrhosis. Treatment with lactulose is of benefit. The possible role of synbiotics (probiotics and fermentable fiber) has not been assessed. We screened 97 consecutive cirrhotic patients without overt hepatic encephalopathy for MHE using the number connection test and measurement of brainstem auditory evoked potentials.

Philip Hilgard, Thomas Schreiter, Richard J. Stockert, Guido Gerken, Ulrich Treichel – 26 April 2004 – Hemolysis in patients with advanced alcoholic liver disease is a common clinical problem and indicates an unfavorable prognosis. In many cases, the etiology of the hemolysis remains unknown. We observed three patients with alcoholic liver disease, suffering from severe hemolytic anemia, requiring multiple blood transfusions. Steroid therapy was ineffective and two of the patients died.

Svetlana Radaeva, Rui Sun, Hong‐na Pan, Feng Hong, Bin Gao – 26 April 2004 – The central role of T cell activation in hepatocellular injury has been well documented. In this article, we provide evidence suggesting that T cells may also play a protective role in liver disease by releasing interleukin‐22 (IL‐22), a recently identified T cell‐derived cytokine whose biological significance is unclear.

Tri H. Le, Stephen H. Caldwell, Jan A. Redick, Bonnie L. Sheppard, Christine A. Davis, Kristen O. Arseneau, Julia C. Iezzoni, Elizabeth E. Hespenheide, Abdullah Al‐Osaimi, Theresa C. Peterson – 26 April 2004 – Megamitochondria with crystalline inclusions (MMC) have been previously described in nonalcoholic fatty liver; however, their distribution within hepatic zones is unknown. We sought to determine this distribution from the core liver biopsy specimens of 31 patients: 8 males and 23 females, age range 21 to 72 years.
