Hepatic stellate cells induce hepatocellular carcinoma cell resistance to sorafenib through the laminin‐332/α3 integrin axis recovery of focal adhesion kinase ubiquitination

Amalia Azzariti, Serena Mancarella, Letizia Porcelli, Anna Elisa Quatrale, Alessandra Caligiuri, Luigi Lupo, Francesco Dituri, Gianluigi Giannelli – 17 September 2016 – In patients with hepatocellular carcinoma (HCC) receiving sorafenib, drug resistance is common. HCC develops in a microenvironment enriched with extracellular matrix proteins including laminin (Ln)‐332, produced by hepatic stellate cells (HSCs). Ln‐332 is the ligand of α3β1 and α6β4 integrins, differently expressed on the HCC cell surface, that deliver intracellular pathways.

Rubicon inhibits autophagy and accelerates hepatocyte apoptosis and lipid accumulation in nonalcoholic fatty liver disease in mice

Satoshi Tanaka, Hayato Hikita, Tomohide Tatsumi, Ryotaro Sakamori, Yasutoshi Nozaki, Sadatsugu Sakane, Yuto Shiode, Tasuku Nakabori, Yoshinobu Saito, Naoki Hiramatsu, Keisuke Tabata, Tsuyoshi Kawabata, Maho Hamasaki, Hidetoshi Eguchi, Hiroaki Nagano, Tamotsu Yoshimori, Tetsuo Takehara – 16 September 2016 – Nonalcoholic fatty liver disease (NAFLD) is the most prevalent liver disease worldwide. It encompasses a spectrum ranging from simple steatosis to fatty liver with hepatocellular injury, termed nonalcoholic steatohepatitis.

Extracellular vesicles in liver pathobiology: Small particles with big impact

Petra Hirsova, Samar H. Ibrahim, Vikas K. Verma, Leslie A. Morton, Vijay H. Shah, Nicholas F. LaRusso, Gregory J. Gores, Harmeet Malhi – 15 September 2016 – Extracellular vesicles (EVs) are nanometer‐sized, membrane‐bound vesicles released by cells into the extracellular milieu. EVs are now recognized to play a critical role in cell‐to‐cell communication. EVs contain important cargo in the form of proteins, lipids, and nucleic acids and serve as vectors for delivering this cargo from donor to acceptor or target cell.
