Promotion of liver regeneration by natural killer cells in a murine model is dependent on extracellular adenosine triphosphate phosphohydrolysis

Nadine Graubardt, René Fahrner, Markus Trochsler, Adrian Keogh, Karin Breu, Cynthia Furer, Deborah Stroka, Simon C. Robson, Emma Slack, Daniel Candinas, Guido Beldi – 16 August 2012 – Nucleotides, such as adenosine triphosphate (ATP), are released by cellular injury, bind to purinergic receptors expressed on hepatic parenchymal and nonparenchymal cells, and modulate cellular crosstalk. Liver resection and resulting cellular stress initiate such purinergic signaling responses between hepatocytes and innate immune cells, which regulate and ultimately drive liver regeneration.

Determination of reliability criteria for liver stiffness evaluation by transient elastography

Jérôme Boursier, Jean‐Pierre Zarski, Victor de Ledinghen, Marie‐Christine Rousselet, Nathalie Sturm, Brigitte Lebail, Isabelle Fouchard‐Hubert, Yves Gallois, Frédéric Oberti, Sandrine Bertrais, Paul Calès, the Multicentric Group from ANRS/HC/EP23 FIBROSTAR Studies – 16 August 2012 – Liver stiffness evaluation (LSE) is usually considered as reliable when it fulfills all the following criteria: ≥10 valid measurements, ≥60% success rate, and interquartile range / median ratio (IQR/M) ≤0.30. However, such reliable LSE have never been shown to be more accurate than unreliable LSE.

Exception point applications for 15 points: An unintended consequence of the Share 15 policy

Therese Bittermann, George Makar, David Goldberg – 16 August 2012 – In 2005, the United Network for Organ Sharing (UNOS) adopted the Share 15 policy to improve organ allocation by facilitating transplantation for local and regional patients with Model for End‐Stage Liver Disease (MELD) scores of 15 or higher. There has been concern that the lack of standardization in the use of exception points is potentially diminishing the benefits of this policy.

Sex bias occurrence of hepatocellular carcinoma in Poly7 molecular subclass is associated with EGFR

Vincent W. Keng, Daniela Sia, Aaron L. Sarver, Barbara R. Tschida, Danhua Fan, Clara Alsinet, Manel Solé, Wai L. Lee, Timothy P. Kuka, Branden S. Moriarity, Augusto Villanueva, Adam J. Dupuy, Jesse D. Riordan, Jason B. Bell, Kevin A. T.Silverstein, Josep M. Llovet, David A. Largaespada – 16 August 2012 – Hepatocellular carcinoma (HCC) is one of the deadliest solid cancers and is the third leading cause of cancer‐related death. There is a universal estimated male/female ratio of 2.5, but the reason for this is not well understood.

FGF3/FGF4 amplification and multiple lung metastases in responders to sorafenib in hepatocellular carcinoma

Tokuzo Arao, Kazuomi Ueshima, Kazuko Matsumoto, Tomoyuki Nagai, Hideharu Kimura, Satoru Hagiwara, Toshiharu Sakurai, Seiji Haji, Akishige Kanazawa, Hisashi Hidaka, Yukihiro Iso, Keiichi Kubota, Mitsuo Shimada, Tohru Utsunomiya, Masashi Hirooka, Yoichi Hiasa, Yoshikazu Toyoki, Kenichi Hakamada, Kohichiroh Yasui, Takashi Kumada, Hidenori Toyoda, Shuichi Sato, Hiroyuki Hisai, Teiji Kuzuya, Kaoru Tsuchiya, Namiki Izumi, Shigeki Arii, Kazuto Nishio, Masatoshi Kudo – 13 August 2012 – The response rate to sorafenib in hepatocellular carcinoma (HCC) is relatively low (0.7%‐3%), however, rapid and d
