Inosine triphosphatase genetic variants are protective against anemia during antiviral therapy for HCV2/3 but do not decrease dose reductions of RBV or increase SVR

Alexander J. Thompson, Rosanna Santoro, Valeria Piazzolla, Paul J. Clark, Susanna Naggie, Hans L. Tillmann, Keyur Patel, Andrew J. Muir, Kevin V. Shianna, Leonardo Mottola, Daniela Petruzzellis, Mario Romano, Fernando Sogari, Domenico Facciorusso, David B. Goldstein, John G. McHutchison, Alessandra Mangia – 12 November 2010 – Two functional variants in the inosine triphosphatase (ITPA) gene causing inosine triphosphatase (ITPase) deficiency protect against ribavirin (RBV)‐induced hemolytic anemia and the need for RBV dose reduction in patients with genotype 1 hepatitis C virus (HCV).

Effect of immune pressure on hepatitis C virus evolution: Insights from a single‐source outbreak

Shahzma Merani, Danijela Petrovic, Ian James, Abha Chopra, Don Cooper, Elizabeth Freitas, Andri Rauch, Julia di Iulio, Mina John, Michaela Lucas, Karen Fitzmaurice, Susan McKiernan, Suzanne Norris, Dermot Kelleher, Paul Klenerman, Silvana Gaudieri – 12 November 2010 – The host's immune response to hepatitis C virus (HCV) can result in the selection of characteristic mutations (adaptations) that enable the virus to escape this response.

Dissociation between APOC3 variants, hepatic triglyceride content and insulin resistance

Julia Kozlitina, Eric Boerwinkle, Jonathan C. Cohen, Helen H. Hobbs – 12 November 2010 – Nonalcoholic fatty liver disease (NAFLD) is an escalating health problem that is frequently associated with obesity and insulin resistance. The mechanistic relationship between NAFLD, obesity, and insulin resistance is not well understood.

Sorafenib suppresses postsurgical recurrence and metastasis of hepatocellular carcinoma in an orthotopic mouse model

Yu‐Xiong Feng, Tao Wang, Yue‐Zhen Deng, Pengyuan Yang, Jing‐Jing Li, Dong‐Xian Guan, Fan Yao, Yin‐Qiu Zhu, Ying Qin, Hui Wang, Nan Li, Meng‐Chao Wu, Hong‐Yang Wang, Xiao‐Fan Wang, Shu‐Qun Cheng, Dong Xie – 12 November 2010 – Surgical resection is the first‐line treatment for hepatocellular carcinoma (HCC) patients with well‐preserved liver function. Nevertheless, the rate of postoperative recurrence at 5 years is as high as 70%, and this gravely jeopardizes the therapeutic outcome. Clearly, new approaches are needed for preventing the relapse of this deadly disease.

Liver transplantation for hepatocellular carcinoma: The impact of human immunodeficiency virus infection

Eric Vibert, Jean‐Charles Duclos‐Vallée, Maria‐Rosa Ghigna, Emir Hoti, Chady Salloum, Catherine Guettier, Denis Castaing, Didier Samuel, René Adam – 4 November 2010 – Liver transplantation (LT) has become an accepted therapy for end‐stage liver disease in human immunodeficiency virus–positive (HIV+) patients, but the specific results of LT for hepatocellular carcinoma (HCC) are unknown. Between 2003 and 2008, 21 HIV+ patients and 65 HIV− patients with HCC were listed for LT at a single institution. Patient characteristics and pathological features were analyzed.

Secular trend of the viral genotype distribution in children with chronic hepatitis B virus infection after universal infant immunization

Wan‐Hsin Wen, Huey‐Ling Chen, Yen‐Hsuan Ni, Hong‐Yuan Hsu, Jia‐Horng Kao, Fu‐Chang Hu, Mei‐Hwei Chang – 4 November 2010 – Genotypes B and C are the major hepatitis B virus (HBV) genotypes in Taiwan, and genotype C is associated with more severe liver disease than genotype B. Whether the implementation of the hepatitis B immunization program has affected the secular trend of the HBV genotype distribution remains unknown.

Hepatocyte nuclear factor‐4 alpha regulates liver triglyceride metabolism in part through secreted phospholipase A2 GXIIB

Min Guan, Linbing Qu, Wenjuan Tan, Ling Chen, Chi‐Wai Wong – 4 November 2010 – Hepatocyte nuclear factor‐4 alpha (HNF‐4α) is an important transcription factor governing the expression of genes involved in multiple metabolic pathways. Secreted phospholipase A2 GXIIB (PLA2GXIIB) is an atypical member of a class of secreted phospholipases A2. We establish in this study that PLA2GXIIB is an HNF‐4α target gene. We demonstrate that HNF‐4α binds to a response element on the PLA2GXIIB promoter. Moreover, HNF‐4α agonists induce PLA2GXIIB expression in human hepatocarcinoma cells.
