HFE C282Y homozygotes are at increased risk of breast and colorectal cancer

Nicholas J. Osborne, Lyle C. Gurrin, Katrina J. Allen, Clare C. Constantine, Martin B. Delatycki, Christine E. McLaren, Dorota M. Gertig, Gregory J. Anderson, Melissa C. Southey, John K. Olynyk, Lawrie W. Powell, John L. Hopper, Graham G. Giles, Dallas R. English – 26 March 2010 – The evidence that mutations in the HFE gene for hemochromatosis are associated with increased cancer risk is inconsistent. The Melbourne Collaborative Cohort Study is a prospective cohort study that commenced recruitment in 1990.

The emerging role of T cell immunoglobulin mucin‐1 in the mechanism of liver ischemia and reperfusion injury in the mouse

Yoichiro Uchida, Bibo Ke, Maria Cecilia S. Freitas, Haofeng Ji, Danyun Zhao, Elizabeth R. Benjamin, Nader Najafian, Hideo Yagita, Hisaya Akiba, Ronald W. Busuttil, Jerzy W. Kupiec‐Weglinski – 26 March 2010 – The T cell immunoglobulin and mucin domain‐containing molecules (TIM) protein family, which is expressed by T cells, plays a crucial role in regulating host adaptive immunity and tolerance. However, its role in local inflammation, such as innate immunity‐dominated organ ischemia–reperfusion injury (IRI), remains unknown.

Nucleotide‐binding oligomerization domain containing 2 (NOD2) variants are genetic risk factors for death and spontaneous bacterial peritonitis in liver cirrhosis

Beate Appenrodt, Frank Grünhage, Martin G. Gentemann, Lydia Thyssen, Tilman Sauerbruch, Frank Lammert – 26 March 2010 – Spontaneous bacterial peritonitis (SBP), a severe complication in patients with advanced liver cirrhosis, has been attributed to bacterial translocation from the intestine. Variants of the NOD2 (nucleotide‐binding oligomerization domain containing 2) gene have been associated with impaired mucosal barrier function in Crohn disease. We hypothesized that the risk of acquiring SBP is increased in patients with cirrhosis carrying NOD2 variants.

Sirolimus‐based immunosuppression is associated with increased survival after liver transplantation for hepatocellular carcinoma

Christian Toso, Shaheed Merani, David L. Bigam, A.M. James Shapiro, Norman M. Kneteman – 26 March 2010 – Liver transplantation is an important treatment option for selected patients with nonresectable hepatocellular carcinoma (HCC). Several reports have suggested a lower risk of posttransplant tumor recurrence with the use of sirolimus and a higher one with calcineurin inhibitors, but the selection of an ideal immunosuppression protocol is still a matter of debate.

Mitogen‐inducible gene‐6 is a negative regulator of epidermal growth factor receptor signaling in hepatocytes and human hepatocellular carcinoma

Markus Reschke, Ingvar Ferby, Ewa Stepniak, Nina Seitzer, David Horst, Erwin F. Wagner, Axel Ullrich – 26 March 2010 – The mitogen‐inducible gene‐6 (mig‐6) is a multi‐adaptor protein implicated in the regulation of the HER family of receptor tyrosine kinases. We have reported recently that mig‐6 is a negative regulator of epidermal growth factor receptor (EGFR)‐dependent skin morphogenesis and tumor formation in vivo. In the liver, ablation of mig‐6 leads to an increase in EGFR protein levels, suggesting that mig‐6 is a negative regulator of EGFR function.
