Hepatitis C virus‐induced up‐regulation of microRNA‐155 promotes hepatocarcinogenesis by activating Wnt signaling

Yiliang Zhang, Wei Wei, Na Cheng, Kaihui Wang, Bin Li, Xiaoqing Jiang, Shuhan Sun – 18 May 2012 – Hepatitis C virus (HCV) infection usually induces chronic hepatic inflammation, which favors the initiation and progression of hepatocellular carcinoma (HCC). Moreover, microRNA‐155 (miR‐155) plays an important role in regulating both inflammation and tumorigenesis. However, little is known about whether and how miR‐155 provides the link between inflammation and cancer. In this study we found that miR‐155 levels were markedly increased in patients infected with HCV.

Impact of disease severity on healthcare costs in patients with chronic hepatitis C (CHC) virus infection

Stuart C. Gordon, Paul J. Pockros, Norah A. Terrault, Robert S. Hoop, Ami Buikema, David Nerenz, Fayez M. Hamzeh – 18 May 2012 – Hepatitis C virus (HCV) infection increases total healthcare costs but the effect of the severity of liver disease associated with chronic hepatitis C (CHC) on healthcare costs has not been well studied. We analyzed the demographics, healthcare utilization, and healthcare costs of CHC patients in a large U.S. private insurance database (January, 2002 to August, 2010), with at least 1 year of baseline enrollment and 30 days of continuous follow‐up.

Droxidopa, an oral norepinephrine precursor, improves hemodynamic and renal alterations of portal hypertensive rats

Mar Coll, Sarai Rodriguez, Imma Raurell, Nahia Ezkurdia, Astrid Brull, Salvador Augustin, Jaime Guardia, Rafael Esteban, María Martell, Joan Genescà – 18 May 2012 – We aimed to evaluate the effects of droxidopa (an oral synthetic precursor of norepinephrine) on the hemodynamic and renal alterations of portal hypertensive rats. Sham, portal vein‐ligated (PVL), and 4‐week biliary duct‐ligated (BDL) rats received a single oral dose of droxidopa (25‐50 mg/kg) or vehicle and hemodynamic parameters were monitored for 2 hours.

The centrosomal protein tax1 binding protein 2 is a novel tumor suppressor in hepatocellular carcinoma regulated by cyclin‐dependent kinase 2

Wai‐Lung Lai, Wing‐Yan Hung, Leo Lap‐Yan Wong, Yuan Zhou, Veronica Yee‐Law Leong, Joyce Man‐Fong Lee, Irene Oi‐Lin Ng, Dong‐Yan Jin, Yick‐Pang Ching – 18 May 2012 – Deregulation of cellular‐signaling pathways by the inactivation of tumor‐suppressor genes is one of the major causes of hepatocellular carcinoma (HCC). In this study, we identified Tax1 binding protein 2 (TAX1BP2) as a novel tumor‐suppressor gene in HCC.
