YAP promotes proliferation, chemoresistance, and angiogenesis in human cholangiocarcinoma through TEAD transcription factors

Patricia Marti, Claudia Stein, Tanja Blumer, Yann Abraham, Michael T. Dill, Monika Pikiolek, Vanessa Orsini, Giorgia Jurisic, Philippe Megel, Zuzanna Makowska, Claudia Agarinis, Luigi Tornillo, Tewis Bouwmeester, Heinz Ruffner, Andreas Bauer, Christian N. Parker, Tobias Schmelzle, Luigi M. Terracciano, Markus H. Heim, Jan S. Tchorz – 14 July 2015 – The Yes‐associated protein (YAP)/Hippo pathway has been implicated in tissue development, regeneration, and tumorigenesis. However, its role in cholangiocarcinoma (CC) is not established.

Toward a more accurate estimate of the prevalence of hepatitis C in the United States

Brian R. Edlin, Benjamin J. Eckhardt, Marla A. Shu, Scott D. Holmberg, Tracy Swan – 14 July 2015 – Data from the 2003‐2010 National Health and Nutrition Examination Survey (NHANES) indicate that about 3.6 million people in the United States have antibodies to the hepatitis C virus, of whom 2.7 million are currently infected. NHANES, however, excludes several high‐risk populations from its sampling frame, including people who are incarcerated, homeless, or hospitalized; nursing home residents; active‐duty military personnel; and people living on Indian reservations.

Plasma cholesteryl ester transfer protein is predominantly derived from Kupffer cells

Yanan Wang, Sam van der Tuin, Nathanja Tjeerdema, Andrea D. van Dam, Sander S. Rensen, Tim Hendrikx, Jimmy F.P. Berbée, Biljana Atanasovska, Jingyuan Fu, Menno Hoekstra, Siroon Bekkering, Niels P. Riksen, Wim A. Buurman, Jan Willem Greve, Marten H. Hofker, Ronit Shiri‐Sverdlov, Onno C. Meijer, Johannes W.A. Smit, Louis M. Havekes, Ko Willems van Dijk, Patrick C.N. Rensen – 14 July 2015 – The role of Kupffer cells (KCs) in the pathophysiology of the liver has been firmly established.

NUMB phosphorylation destabilizes p53 and promotes self‐renewal of tumor‐initiating cells by a NANOG‐dependent mechanism in liver cancer

Hifzur R. Siddique, Douglas E. Feldman, Chia‐Lin Chen, Vasu Punj, Hiroshi Tokumitsu, Keigo Machida – 14 July 2015 – Stem cell populations are maintained through self‐renewing divisions in which one daughter cell commits to a particular fate whereas the other retains the multipotent characteristics of its parent. The NUMB, a tumor suppressor, in conjunction with another tumor‐suppressor protein, p53, preserves this property and acts as a barrier against deregulated expansion of tumor‐associated stem cells.

Is hepatitis E virus an emerging problem in industrialized countries?

Ibrahim M. Sayed, Ann‐Sofie Vercouter, Sayed F. Abdelwahab, Koen Vercauteren, Philip Meuleman – 14 July 2015 – Hepatitis E virus (HEV) is yearly responsible for approximately 20 million infections worldwide. Although most infections occur in developing countries, HEV appears to be an emerging problem in several industrialized countries, where it is mostly associated with either traveling to an HEV endemic area or contact with pigs, which represent a major reservoir of HEV.

Depletion of B cells induces remission of autoimmune hepatitis in mice through reduced antigen presentation and help to T cells

Kathie Béland, Gabriel Marceau, Agathe Labardy, Sara Bourbonnais, Fernando Alvarez – 14 July 2015 – Autoimmune hepatitis (AIH) is known as a T cell–mediated disease. However, AIH patients refractory to conventional treatment have been successfully treated with anti‐CD20‐mediated B‐cell depletion. The aim of this project was to understand the immunological changes underlying the AIH remission caused by B‐cell depletion in an experimental model of AIH.
