Up‐regulated microRNA‐143 transcribed by nuclear factor kappa B enhances hepatocarcinoma metastasis by repressing fibronectin expression

Xiaoying Zhang, Shanrong Liu, Tingsong Hu, Shupeng Liu, Ying He, Shuhan Sun – 29 July 2009 – It is increasingly clear that hepatocellular carcinoma (HCC) has a distinct microRNA (miRNA) expression profile that is involved in malignancy; however, little is known about how functional miRNA modulates the metastasis of hepatitis B virus (HBV)‐related HCC (HBV‐HCC). In the present study, we demonstrate that the levels of miRNA‐143 (miR‐143) are dramatically increased in metastatic HBV‐HCC of both p21‐HBx transgenic mice and HCC patients.

Survival after liver transplantation for hepatocellular carcinoma in the model for end‐stage liver disease and pre–model for end‐stage liver disease eras and the independent impact of hepatitis C virus

Paul J. Thuluvath, Anurag Maheshwari, Nimisha P. Thuluvath, Geoffrey C. Nguyen, Dorry L. Segev – 26 June 2009 – It has been suggested that hepatitis C virus (HCV) patients with hepatocellular carcinoma (HCC) may have worse outcomes after liver transplantation (LT) because of more aggressive tumor biology. In this study, we determined the post‐LT survival of HCC patients with and without HCV using United Network for Organ Sharing data from January 1994 to March 2008. Patients with HCC were stratified into HCV (HCC‐HCV) and non‐HCV (HCC–non‐HCV) groups.

Impaired autophagic clearance after cold preservation of fatty livers correlates with tissue necrosis upon reperfusion and is reversed by hypothermic reconditioning

Thomas Minor, Judith Stegemann, Andreas Hirner, Martina Koetting – 26 June 2009 – Fatty livers are particularly susceptible to mitochondrial alterations after cold preservation. We thus aimed to improve graft integrity by brief hypothermic oxygenation prior to warm reperfusion. Macrovesicular steatosis was induced in rat livers by fasting and subsequent feeding of a fat‐free diet enriched with carbohydrates. Fatty livers were retrieved and stored ischemically at 4°C for 20 hours in histidine‐tryptophan‐ketoglutarate solution.

Worse recent efficacy of antiviral therapy in liver transplant recipients with recurrent hepatitis C: Impact of donor age and baseline cirrhosis

Marina Berenguer, Victoria Aguilera, Martín Prieto, Cecilia Ortiz, Maria Rodríguez, Federica Gentili, Blas Risalde, Angel Rubin, Raquel Cañada, Antonio Palau, Jose‐Miguel Rayón – 26 June 2009 – We hypothesized that antiviral efficacy [sustained virologic response (SVR)] has improved in recent years in the transplant setting. Our aim was to assess whether the efficacy of pegylated interferon (PegIFN)–ribavirin (Rbv) has improved over time.
