Postreperfusion microcirculatory derangements after liver transplantation: Relationship to hemodynamics, serum mediators, and outcome

Carlo Pulitano, David Joseph, Charbel Sandroussi, Deborah Verran, Phong Ho, Ashe Debiasio, Adriano Luongo, Geoffrey W. McCaughan, Nicholas A. Shackel, Michael Crawford – 10 January 2017 – Despite the growing data supporting the role of microcirculation in regulating liver function, little of this knowledge has been translated into clinical practice. The aim of this study is to quantify hepatic microcirculation in vivo using sidestream dark field (SDF) imaging and correlate these findings with hepatic blood flow, hemodynamic parameters, and soluble mediators.

Functional lipidomics: Palmitic acid impairs hepatocellular carcinoma development by modulating membrane fluidity and glucose metabolism

Ling Lin, Ying Ding, Yi Wang, Zhenxin Wang, Xuefei Yin, Guoquan Yan, Lei Zhang, Pengyuan Yang, Huali Shen – 10 January 2017 – Lipids are essential cellular components and energy sources of living organisms, and altered lipid composition is increasingly recognized as a signature of cancer. We performed lipidomic analysis in a series of hepatocellular carcinoma (HCC) cells and identified over 1,700 intact lipids originating from three major lipid categories.

The PNPLA3 I148M variant modulates the fibrogenic phenotype of human hepatic stellate cells

Francesca Virginia Bruschi, Thierry Claudel, Matteo Tardelli, Alessandra Caligiuri, Thomas M. Stulnig, Fabio Marra, Michael Trauner – 10 January 2017 – The genetic polymorphism I148M of patatin‐like phospholipase domain–containing 3 (PNPLA3) is robustly associated with hepatic steatosis and its progression to steatohepatitis, fibrosis, and cancer. Hepatic stellate cells (HSCs) are key players in the development of liver fibrosis, but the role of PNPLA3 and its variant I148M in this process is poorly understood.

Activation of the c‐Jun N‐terminal kinase pathway aggravates proteotoxicity of hepatic mutant Z alpha1‐antitrypsin

Nunzia Pastore, Sergio Attanasio, Barbara Granese, Raffaele Castello, Jeffrey Teckman, Andrew A. Wilson, Andrea Ballabio, Nicola Brunetti‐Pierri – 10 January 2017 – Alpha1‐antitrypsin deficiency is a genetic disease that can affect both the lung and the liver. The vast majority of patients harbor a mutation in the serine protease inhibitor 1A (SERPINA1) gene leading to a single amino acid substitution that results in an unfolded protein that is prone to polymerization.

A liver‐specific long noncoding RNA with a role in cell viability is elevated in human nonalcoholic steatohepatitis

Biljana Atanasovska, Sander S. Rensen, Marijke R. Sijde, Glenn Marsman, Vinod Kumar, Iris Jonkers, Sebo Withoff, Ronit Shiri‐Sverdlov, Jan Willem M. Greve, Klaas Nico Faber, Han Moshage, Cisca Wijmenga, Bart van de Sluis, Marten H. Hofker, Jingyuan Fu – 10 January 2017 – Hepatocyte apoptosis in nonalcoholic steatohepatitis (NASH) can lead to fibrosis and cirrhosis, which permanently damage the liver. Understanding the regulation of hepatocyte apoptosis is therefore important to identify therapeutic targets that may prevent the progression of NASH to fibrosis.
