Brown, Jidong Jia – 26 January 2008 – Chronic hepatitis B and its life‐threatening sequelae are highly prevalent in China. There is a need for effective new therapies to suppress hepatitis B virus (HBV) replication and ameliorate liver disease.

Marta Massip‐Salcedo, M. Amine Zaouali, Susagna Padrissa‐Altés, Arani Casillas‐Ramirez, Joan Rodés, Joan Roselló‐Catafau, Carmen Peralta – 26 January 2008 – Hepatic steatosis is a major risk factor in ischemia–reperfusion (I/R). Adiponectin acts as an antiobesity and anti‐inflammatory hormone. Adiponectin activates peroxisome proliferator‐activated receptor‐α (PPAR‐α), a transcription factor that regulates inflammation in liver disease.

Eleonora Distrutti, Andrea Mencarelli, Luca Santucci, Barbara Renga, Stefano Orlandi, Annibale Donini, Vijay Shah, Stefano Fiorucci – 26 January 2008 – Increased intrahepatic resistance in cirrhotic livers is caused by endothelial dysfunction and impaired formation of two gaseous vasodilators, nitric oxide (NO) and hydrogen sulfide (H2S). Homocysteine, a sulfur‐containing amino acid and H2S precursor, is formed from hepatic methionine metabolism. In the systemic circulation, hyperhomocystenemia impairs vasodilation and NO production from endothelial cells.

Komal Ramani, Heping Yang, Meng Xia, Ainhoa Iglesias Ara, José M. Mato, Shelly C. Lu – 26 January 2008 – Leptin is an adiopokine that plays a pivotal role in the progression of liver fibrogenesis and carcinogenesis. Recently, leptin was shown to be mitogenic in human liver cancer cell lines HepG2 and Huh7. Whether leptin can act as a mitogen in normal hepatocytes is unclear. Methionine adenosyltransferase (MAT) is an essential enzyme that catalyzes the formation of S‐adenosylmethionine (SAMe), the principal methyl donor and precursor of polyamines.

Ning‐Fang Ma, Liang Hu, Jackie M. Fung, Dan Xie, Bo‐Jian Zheng, Leilei Chen, Dong‐Jiang Tang, Li Fu, Zhenguo Wu, Muhan Chen, Yan Fang, Xin‐Yuan Guan – 26 January 2008 – Amplification of 1q21 is the most frequent genetic alteration in human hepatocellular carcinoma (HCC), being detected in 58%‐78% of primary HCC cases by comparative genomic hybridization. Recently, we isolated a candidate oncogene, Amplified in Liver Cancer 1 (ALC1), from 1q21 by hybrid selection. Here we demonstrate that ALC1 was frequently amplified and overexpressed in HCC.
