Impact of patatin‐like phospholipase‐3 (rs738409 C>G) polymorphism on fibrosis progression and steatosis in chronic hepatitis C

Eric Trépo, Pierre Pradat, Andrej Potthoff, Yukihide Momozawa, Eric Quertinmont, Thierry Gustot, Arnaud Lemmers, Pascale Berthillon, Leila Amininejad, Michéle Chevallier, Jerome Schlué, Hans Kreipe, Jacques Devière, Michael Manns, Christian Trépo, John Sninsky, Heiner Wedemeyer, Denis Franchimont, Christophe Moreno – 12 April 2011 – Only 20% of patients with chronic hepatitis C (CHC) will develop cirrhosis, and fibrosis progression remains highly unpredictable.

Lack of de novo phosphatidylinositol synthesis leads to endoplasmic reticulum stress and hepatic steatosis in cdipt‐deficient zebrafish

Prakash C. Thakur, Carsten Stuckenholz, Marcus R. Rivera, Jon M. Davison, Jeffrey K. Yao, Adam Amsterdam, Kirsten C. Sadler, Nathan Bahary – 12 April 2011 – Hepatic steatosis is the initial stage of nonalcoholic fatty liver disease (NAFLD) and may predispose to more severe hepatic disease, including hepatocellular carcinoma. Endoplasmic reticulum (ER) stress has been recently implicated as a novel mechanism that may lead to NAFLD, although the genetic factors invoking ER stress are largely unknown.

Risk factors for cholangiocarcinoma

Gia L. Tyson, Hashem B. El‐Serag – 12 April 2011 – Cholangiocarcinoma (CC) is the second most common primary hepatic malignancy after hepatocellular cancer. CC accounts for approximately 10%‐25% of all hepatobiliary malignancies. There are considerable geographic and demographic variations in the incidence of CC. There are several established risk factors for CC, including parasitic infections, primary sclerosing cholangitis, biliary‐duct cysts, hepatolithiasis, and toxins.

Fatty liver index and mortality: The cremona study in the 15th year of follow‐up

Giliola Calori, Guido Lattuada, Francesca Ragogna, Maria Paola Garancini, Paolo Crosignani, Marco Villa, Emanuele Bosi, Giacomo Ruotolo, Lorenzo Piemonti, Gianluca Perseghin – 12 April 2011 – A fatty liver, which is a common feature in insulin‐resistant states, can lead to chronic liver disease. It has been hypothesized that a fatty liver can also increase the rates of non–hepatic‐related morbidity and mortality.

Cancer risk in chronic hepatitis B: Do genome‐wide association studies hit the mark?

Markus Casper, Frank Grünhage, Frank Lammert – 7 April 2011 – To identify susceptibility variants for hepatitis B virus (HBV)‐related hepatocellular carcinoma (HCC), we conducted a genome‐wide association study by genotyping 440,794 SNPs in 355 chronic HBV carriers with HCC and 360 chronic HBV carriers without HCC, all of Chinese ancestry.

CD13: Waving the flag for a novel cancer stem cell target

Bruno Christ, Peggy Stock, Matthias M. Dollinger – 7 April 2011 – Cancer stem cells (CSCs) are generally dormant or slowly cycling tumor cells that have the ability to reconstitute tumors. They are thought to be involved in tumor resistance to chemo/radiation therapy and tumor relapse and progression. However, neither their existence nor their identity within many cancers has been well defined.

Hepatocyte turnover and regeneration: Virtually a virtuoso performance

Malcolm R. Alison, Wey‐Ran Lin – 7 April 2011 – The liver and exocrine pancreas share a common structure, with functioning units (hepatic plates and pancreatic acini) connected to the ductal tree. Here we show that Sox9 is expressed throughout the biliary and pancreatic ductal epithelia, which are connected to the intestinal stem‐cell zone. Cre‐based lineage tracing showed that adult intestinal cells, hepatocytes and pancreatic acinar cells are supplied physiologically from Sox9‐expressing progenitors.
