Effects of polyamine imbalance on the induction of stress genes in hepatocarcinoma cells exposed to heat shock

M A Desiderio, L Tacchini, E Anzon, G Pogliaghi, L Radice, A Bernelli‐Zazzera – 1 July 1996 – The expression of hsp70–the inducible member of the corresponding heat shock gene family‐of the oxidative stress marker gene heme oxygenase (HOx), and of the immediate early response genes c‐fos and c‐jun has been studied in FAO hepatocarcinoma cells depleted of polyamines and exposed to heat shock.

The polymeric immunoglobulin receptor is the major calmodulin‐binding protein in an endosome fraction from rat liver enriched in recycling receptors

C Enrich, S Jäckle, R J Havel – 1 July 1996 – Rat liver endosomes contain one major high‐affinity calmodulin‐binding protein (CaMBP) that now has been identified as the polymeric immunoglobulin receptor (pIgR). In isolated endosomes pIgR was enriched in the receptor‐recycling compartment (RRC); lesser enrichment was found in ‘early’ endosome (CURL) and much less in ‘late’ endosome fractions (multivesicular bodies, MVB).

Experimental Mallory body formation is accompanied by modulation of the expression of multidrug‐resistance genes and their products

K Preisegger, C Stumptner, D Riegelnegg, P C Brown, J A Silverman, S S Thorgeirsson, H Denk – 1 July 1996 – Mallory bodies (MBs) are characteristic morphological features of alcoholic hepatitis and are also found in other chronic liver disorders and hepatocellular neoplasms. MBs can be produced in mouse liver by chronic administration of the porphyrinogenic drugs griseofulvin (GF) and 3,5‐diethoxy‐carbonyl‐1,4‐dihydrocollidine (DDC). The mechanisms causing the formation of MBs are poorly understood, and the significance of MB formation during the course of liver disease remains unclear.

Choline transport in rat liver basolateral plasma membrane vesicles

R H Moseley, H Takeda, L J Zugger – 1 July 1996 – Previous studies have demonstrated several pathways for the sinusoidal uptake of endogenous and exogenous organic cations, including two distinct organic cation:H+ exchanges and a separate carrier‐mediated system driven by the inside‐negative membrane potential. In this study, the driving force(s) for the uptake of the endogenous quaternary amine, choline, were determined in rat liver basolateral plasma membrane (blLPM) vesicles.

Hepatotoxicity of the herbal medicine germander: Metabolic activation of its furano diterpenoids by cytochrome P450 3A Depletes cytoskeleton‐associated protein thiols and forms plasma membrane blebs in rat hepatocytes

M Lekehal, D Pessayre, J M Lereau, C Moulis, I Fourasté, D Fau – 1 July 1996 – Several herbal remedies have produced hepatitis in humans. The medicinal plant, germander, was recalled after its use as an adjuvant to slimming diets resulted in an epidemic of hepatitis in France. We studied the hepatotoxicity of germander in isolated rat hepatocytes.

Famciclovir treatment of hepatitis B virus recurrence after liver transplantation: A pilot study

Martin Krüger, Hans Ludger Tillmann, Christian Trautwein, Ulrike Bode, Karl Oldhafer, Hansjörg Maschek, Klaus H. W. Böker, Christoph E. Broelsch, Rudolf Pichlmayr, Michael P. Manns – 1 July 1996 – Despite hepatitis B immunoprophylaxis hepatitis B virus (HBV) recurrence is a frequent and often fatal complication after orthotopic liver transplantation (OLT). The purine nucleoside analogues penciclovir and its oral form famciclovir (FCV) proved to be well tolerated and effective against herpes simplex and zoster virus infections.

The surgical challenge of papillary neoplasia of the biliary tract

Thomas S. Helling, R. Scott Strobach – 1 July 1996 – This study is a case report and literature review of the surgical approach to papillary lesions of the biliary tract exclusive of the ampulla of Vater. Papillary lesions of the bile ducts, exclusive of the ampulla of Vater, are distinctly uncommon but, because of their unpredictable and aggressive behavior, pose challenging problems for the surgeon.
