A sensitive bead assay for antimitochondrial antibodies: Chipping away at AMA‐negative primary biliary cirrhosis

Sabine Oertelt, Roman Rieger, Carlo Selmi, Pietro Invernizzi, Aftab A. Ansari, Ross L. Coppel, Mauro Podda, Patrick S.C. Leung, M. Eric Gershwin – 26 February 2007 – The antimitochondrial response in primary biliary cirrhosis (PBC) is the most highly directed and specific self‐reacting antibody in human immunopathology. Originally, antimitochondrial antibodies (AMAs) were detected by indirect immunofluorescence (IIF) and found in approximately 90% of well‐documented patients with PBC.

TRAIL/bortezomib cotreatment is potentially hepatotoxic but induces cancer‐specific apoptosis within a therapeutic window

Ronald Koschny, Tom M. Ganten, Jaromir Sykora, Tobias L. Haas, Martin R. Sprick, Armin Kolb, Wolfgang Stremmel, Henning Walczak – 26 February 2007 – Tumor necrosis factor‐related apoptosis‐inducing ligand (TRAIL) represents a novel promising anticancer biotherapeutic. However, TRAIL‐resistant tumor cells require combinatorial regimens to sensitize tumor but not normal cells for TRAIL‐induced apoptosis.

Protection against Fas‐induced liver apoptosis in transgenic mice expressing cyclooxygenase 2 in hepatocytes

Marta Casado, Belén Mollá, Rosa Roy, Amalia Fernández‐Martínez, Carme Cucarella, Rafael Mayoral, Lisardo Boscá, Paloma Martín‐Sanz – 26 February 2007 – Cyclooxygenase‐2 (COX‐2) is upregulated in many cancers, and the prostanoids synthesized increase proliferation, improve angiogenesis, and inhibit apoptosis in several tissues. To explore the function of COX‐2 in liver, transgenic (Tg) mice were generated containing a fusion gene (LIVhCOX‐2) consisting of human COX‐2 cDNA under the control of the human ApoE promoter.
