Kangsheng Tu, Jiachu Li, Vikas K. Verma, Chunsheng Liu, Daniel D. Billadeau, Georg Lamprecht, Xiaoyu Xiang, Luyang Guo, Renumathy Dhanasekaran, Lewis R. Roberts, Vijay H. Shah, Ningling Kang – 10 June 2014 – Liver microenvironment is a critical determinant for development and progression of liver metastasis. Under transforming growth factor beta (TGF‐β) stimulation, hepatic stellate cells (HSCs), which are liver‐specific pericytes, transdifferentiate into tumor‐associated myofibroblasts that promote tumor implantation (TI) and growth in the liver.

Joel Wedd, Kiran M. Bambha, Matt Stotts, Heather Laskey, Jordi Colmenero, Jane Gralla, Scott W. Biggins – 10 June 2014 – The Model for End‐Stage Liver Disease (MELD) score has reduced predictive ability in patients with cirrhosis and MELD scores ≤ 20. We aimed to assess whether a 5‐stage clinical model could identify liver transplantation (LT) candidates with low MELD scores who are at increased risk for death. We conducted a case‐control study of subjects with cirrhosis and MELD scores ≤ 20 who were awaiting LT at a single academic medical center between February 2002 and May 2011.

Eriks Smagris, Soumik BasuRay, John Li, Yongcheng Huang, Ka‐man V. Lai, Jesper Gromada, Jonathan C. Cohen, Helen H. Hobbs – 10 June 2014 – A sequence polymorphism (rs738409, I148M) in patatin‐like phospholipid domain containing protein 3 (PNPLA3) is strongly associated with nonalcoholic fatty liver disease (NAFLD), but the mechanistic basis for this association remains enigmatic. Neither ablation nor overexpression of wild‐type PNPLA3 affects liver fat content in mice, whereas hepatic overexpression of the human 148M transgene causes steatosis.

Fen Qiang Li, Gi‐Young Ko, Kyu‐Bo Sung, Dong‐Il Gwon, Heung Kyu Ko, Jong Woo Kim, Eunsil Yu – 10 June 2014 – The purpose of this study was to evaluate the efficacy and safety of transfemoral liver biopsy with a Quick‐Core biopsy needle in select living donor liver transplantation (LDLT) recipients. Eight LDLT recipients underwent 9 transfemoral liver biopsy sessions. Six patients had undergone modified right lobe (mRL) LDLT, and 2 patients had undergone dual–left lobe LDLT.

Jiacheng Bi, Xiaodong Zheng, Yongyan Chen, Haiming Wei, Rui Sun, Zhigang Tian – 9 June 2014 – Overactivation of innate immunity, particularly natural killer (NK) cells, is harmful to liver regeneration; however, the molecular mechanisms that limit NK cell overactivation during liver regeneration are still elusive. Here we show that a coinhibitory receptor, T cell Ig and ITIM domain (TIGIT), was selectively up‐regulated on NK cells, along with high expression of its ligand, poliovirus receptor (PVR/CD155), on hepatocytes during liver regeneration.
