Modeling hepatitis B virus X–induced hepatocellular carcinoma in mice with the sleeping beauty transposon system

Vincent W. Keng, Barbara R. Tschida, Jason B. Bell, David A. Largaespada – 24 November 2010 – The mechanisms associated with hepatitis B virus (HBV)–induced hepatocellular carcinoma (HCC) remain elusive, and there are currently no well‐established animal models for studying this disease. Using the Sleeping Beauty transposon as a delivery system, we introduced an oncogenic component of HBV, the hepatitis B virus X (HBx) gene, into the livers of fumarylacetoacetate hydrolase (Fah) mutant mice via hydrodynamic tail vein injections.

The balancing act of hepatocyte apoptosis

Nicholas A. Shackel – 23 November 2010 – The cell death receptor Fas plays a role in the establishment of fulminant hepatitis, a major cause of drug‐induced liver failure. Fas activation elicits extrinsic apoptotic and hepatoprotective signals; however, the mechanisms by which these signals are integrated during disease are unknown. Tissue inhibitor of metalloproteinases 3 (TIMP3) controls the critical sheddase a disintegrin and metalloproteinase 17 (ADAM17) and may dictate stress signaling.
