Kristin Berry, George N. Ioannou – 27 March 2013 – We aimed to determine whether combining serum alpha‐fetoprotein (AFP) level with hepatocellular carcinoma (HCC) tumor burden would allow better stratification of posttransplant survival for patients with HCC undergoing liver transplantation. Adjusting for donor and recipient characteristics, we calculated the risk of posttransplant mortality associated with serum AFP level or HCC tumor burden for all first‐time adult liver transplants performed in the United States between 2002 and 2011 (n = 45,267).

Tiangang Li, Jessica M. Francl, Shannon Boehme, John Y. L. Chiang – 27 March 2013 – Bile acid synthesis not only produces physiological detergents required for intestinal nutrient absorption, but also plays a critical role in regulating hepatic and whole‐body metabolic homeostasis. We recently reported that overexpression of cholesterol 7α‐hydroxylase (CYP7A1) in the liver resulted in improved metabolic homeostasis in Cyp7a1 transgenic (Cyp7a1‐tg) mice. This study further investigated the molecular links between bile acid metabolism and lipid homeostasis.

In search for a small, nonhuman primate model, we investigated the prevalence of HBV infection in 260 macaque (Cercopithecidae) sera of various geographical origins (i.e., Morocco, Mauritius Island, and Asia).

Elisa Herraez, Elisa Lozano, Rocio I.R. Macias, Javier Vaquero, Luis Bujanda, Jesus M. Banales, Jose J.G. Marin, Oscar Briz – 26 March 2013 – Reduced drug uptake is an important mechanism of chemoresistance. Down‐regulation of SLC22A1 encoding the organic cation transporter‐1 (OCT1) may affect the response of hepatocellular carcinoma (HCC) and cholangiocarcinoma (CGC) to sorafenib, a cationic drug. Here we investigated whether SLC22A1 variants may contribute to sorafenib chemoresistance.

Adeline Bertola, Ogyi Park, Bin Gao – 26 March 2013 – Chronic plus binge ethanol feeding acts synergistically to induce liver injury in mice, but the mechanisms underlying this phenomenon remain unclear. Here, we show that chronic plus binge ethanol feeding synergistically up‐regulated the hepatic expression of interleukin‐1β and tumor necrosis factor alpha and induced neutrophil accumulation in the liver, compared with chronic or binge feeding alone.

To date, the role of miRNAs in liver development is not fully understood.
