Inhibition of natural killer cells protects the liver against acute injury in the absence of glycine N‐methyltransferase

Laura Gomez‐Santos, Zigmund Luka, Conrad Wagner, Sara Fernandez‐Alvarez, Shelly C. Lu, Jose M. Mato, Maria L. Martinez‐Chantar, Naiara Beraza – 5 March 2012 – Glycine N‐methyltransferase (GNMT) catabolizes S‐adenosylmethionine (SAMe), the main methyl donor of the body. Patients with cirrhosis show attenuated GNMT expression, which is absent in hepatocellular carcinoma (HCC) samples. GNMT−/− mice develop spontaneous steatosis that progresses to steatohepatitis, cirrhosis, and HCC.

TAT‐apoptosis repressor with caspase recruitment domain protein transduction rescues mice from fulminant liver failure

Junfeng An, Christoph Harms, Gisela Lättig‐Tünnemann, Gernot Sellge, Ana D. Mandić, Yann Malato, Arnd Heuser, Matthias Endres, Christian Trautwein, Stefan Donath – 5 March 2012 – Acute liver failure (ALF) is associated with massive hepatocyte cell death and high mortality rates. Therapeutic approaches targeting hepatocyte injury in ALF are hampered by the activation of distinct stimulus‐dependent pathways, mechanism of cell death, and a limited therapeutic window.
