Clinical outcomes of patients with hepatorenal syndrome after living donor liver transplantation

Jung Pyo Lee, Hyuk Yong Kwon, Ji In Park, Nam‐Joon Yi, Kyung‐Suk Suh, Hae Won Lee, Myounghee Kim, Yun Kyu Oh, Chun Soo Lim, Yon Su Kim – 19 June 2012 – Liver transplantation (LT) is the treatment of choice for hepatorenal syndrome (HRS). However, the clinical benefits of living donor liver transplantation (LDLT) are not yet well established. We, therefore, investigated the outcomes of patients with HRS who underwent LDLT and patients with HRS who received transplants from deceased donors.

Overexpression of CXCL5 mediates neutrophil infiltration and indicates poor prognosis for hepatocellular carcinoma

Shao‐Lai Zhou, Zhi Dai, Zheng‐Jun Zhou, Xiao‐Ying Wang, Guo‐Huan Yang, Zheng Wang, Xiao‐Wu Huang, Jia Fan, Jian Zhou – 18 June 2012 – CXCL5 (epithelial neutrophil‐activating peptide‐78) is a member of a proangiogenic subgroup of the CXC‐type chemokine family of small, secreted proteins. Recently, evidence that CXCL5 is involved in carcinogenesis and cancer progression has emerged.

Protective role of V‐set and immunoglobulin domain‐containing 4 expressed on kupffer cells during immune‐mediated liver injury by inducing tolerance of liver T‐ and natural killer T‐cells

Keunok Jung, Miseon Kang, Cheol Park, Yung Hyun Choi, Youkyung Jeon, Se‐Ho Park, Su‐Kil Seo, Dan Jin, Inhak Choi – 18 June 2012 – V‐set and Ig domain‐containing 4 (VSIG4, CRIg, or Z39Ig), a newly identified B7‐related cosignaling molecule, is a complement receptor and a coinhibitory ligand that negatively regulates T‐cell immunity. Despite its exclusive expression on liver Kupffer cells (KCs) that play key roles in liver tolerance, the physiological role of VSIG4 in liver tolerance remains undefined.

The liver‐specific tumor suppressor STAT5 controls expression of the reactive oxygen species–generating enzyme NOX4 and the proapoptotic proteins PUMA and BIM in mice

Ji Hoon Yu, Bing‐Mei Zhu, Gregory Riedlinger, Keunsoo Kang, Lothar Hennighausen – 18 June 2012 – Loss of signal transducer and activator of transcription 5 (STAT5) from liver tissue results in steatosis and enhanced cell proliferation. This study demonstrates that liver‐specific Stat5‐null mice develop severe hepatic steatosis as well as hepatocellular carcinomas at 17 months of age, even in the absence of chemical insults. To understand STAT5′s role as a tumor suppressor, we identified and investigated new STAT5 target genes.

Hepatitis B virus X protein modulates oncogene yes‐associated protein by CREB to promote growth of hepatoma cells

Tao Zhang, Junping Zhang, Xiaona You, Qian Liu, Yumei Du, Yuen Gao, Changliang Shan, Guangyao Kong, Youliang Wang, Xiao Yang, Lihong Ye, Xiaodong Zhang – 18 June 2012 – Hepatitis B virus X protein (HBx) plays critical roles in the development of hepatocellular carcinogenesis (HCC). Yes‐associated protein (YAP), a downstream effector of the Hippo‐signaling pathway, is an important human oncogene. In the present article, we report that YAP is involved in the hepatocarcinogenesis mediated by HBx.

High sustained virologic response rates in rapid virologic response patients in the large real‐world PROPHESYS cohort confirm results from randomized clinical trials

Patrick Marcellin, Hugo Cheinquer, Manuela Curescu, Geoffrey M. Dusheiko, Peter Ferenci, Andrzej Horban, Donald Jensen, Gabriella Lengyel, Alessandra Mangia, Denis Ouzan, Massimo Puoti, Maribel Rodriguez‐Torres, Mitchell L. Shiffman, Manuela Schmitz, Fernando Tatsch, Mario Rizzetto – 18 June 2012 – The ability to predict which patients are most likely to achieve a sustained virologic response (SVR) with peginterferon/ribavirin would be useful in optimizing treatment for hepatitis C virus (HCV).
