Inhibition of experimentally induced cirrhosis in rats by hypothyroidism

R Oren, I Dotan, M Papa, Y Marravi, H Aeed, J Barg, L Zeidel, R Bruck, Z Halpern – 1 August 1996 – The coexistence of hyperkinetic circulation, hypermetabolism, and hyperactivity of the sympathetic nervous system is encountered in both cirrhosis and hyperthyroidism. Several drugs, such as propylthiouracil and propranolol, that are beneficial for treating some patients with chronic liver diseases are also prescribed for the treatment of thyrotoxicosis.

Transplantation of conditionally immortalized hepatocytes to treat hepatic encephalopathy

I K Schumacher, T Okamoto, B Kim, N R Chowdhury, J R Chowdhury, I J Fox – 1 August 1996 – Transplantation of hepatocytes has been shown to provide metabolic support during liver failure in experimental models. The potential clinical application of hepatocyte transplantation, however, is limited by the need for readily available, well‐characterized cells, and a worldwide shortage of donor organs.

The peptide‐based thrombin inhibitor CRC 220 is a new substrate of the basolateral rat liver organic anion‐transporting polypeptide

U Eckhardt, J A Horz, E Petzinger, W Stüber, M Reers, G Dickneite, H Daniel, M Wagener, B Hagenbuch, B Stieger, P J Meier – 1 August 1996 – The peptidomimetic thrombin inhibitor CRC 220, 4‐methoxy‐2,3,6‐trimethylphenylsulfonyl‐L‐aspartyl‐D‐4‐amidinop henylalanyl‐ piperidide, is taken up into isolated rat hepatocytes through active, carrier‐mediated transport. This uptake is inhibited by bile acids. Functional expression in Xenopus laevis oocytes was performed to identify the transport system responsible for the hepatocellular CRC 220 uptake. Injection of poly(A)+RNA in X.

Intravenous administration of follistatin: Delivery to the liver and effect on liver regeneration after partial hepatectomy

K Kogure, Y Zhang, M Kanzaki, W Omata, T Mine, I Kojima – 1 August 1996 – When 1 μg 125I‐follistatin was administered into a rat intravenously, radioactivity levels in serum decreased rapidly. Analysis with a biexponential equation showed that the initial half‐ life and the terminal half‐life were 4.0 and 130.8 minutes, respectively. After 2 hours of infusion, approximately 9% of the follistatin infused remained in the liver, which was much more than that in kidney, spleen, pancreas, intestine, or lung.

Expression of hepatocyte growth factor, transforming growth factor α, and transforming growth factor β 1 messenger RNA in various human liver diseases and correlation with hepatocyte proliferation

M Masuhara, M Yasunaga, K Tanigawa, F Tamura, S Yamashita, I Sakaida, K Okita – 1 August 1996 – Hepatocyte growth factor (HGF) and transforming growth factor α (TGF‐α) stimulate liver regeneration, whereas transforming growth factor β 1 (TGF‐β 1) inhibits it in rats. However their significance in human liver diseases, especially in severe acute liver injury, remains unclear. We studied HGF, TGF‐α, and TGF‐β 1 messenger RNA (mRNA) expression in the livers of patients with live diseases using a competitive reverse transcriptase polymerase chain reaction.

Current therapy for Crigler‐Najjar syndrome type 1: Report of a world registry

C N van der Veere, M Sinaasappel, A F McDonagh, P Rosenthal, P Labrune, M Odiévre, J Fevery, J Otte, P McClean, G Bürk, V Masakowski, W Sperl, A P Mowat, G M Vergani, K Heller, J P Wilson, R Shepherd, P L Jansen – 1 August 1996 – This study represents a multicenter survey on the management of patients with Crigler‐Najjar syndrome (CNS) type 1. The aim of the survey was to find guiding principles for physicians in the care of these patients. Fifty‐seven patients were included. At the time of inclusion, 21 patients had received a liver transplant (37%).

Inhibition of viral replication by genetically engineered mutants of the duck hepatitis B virus core protein

F von Weizsäcker, S Wieland, H E Blum – 1 August 1996 – The hepatitis B virus (HBV) nucleocapsid consists of 240 viral core proteins that are arranged in a highly symmetrical structure, HBV replication can only take place inside intact nucleocapsids. In the present study, we investigated whether genetically engineered core mutants can inhibit viral replication by interfering with the formation of intact nucleocapsids. Using the duck hepatitis B virus (DHBV) model, a series of core protein mutants was generated.

Blocking late cholesterol biosynthesis inhibits the growth of transplanted Morris hepatomas (7288CTC) in rats

G Xu, G Salen, M Lea, G S Tint, L B Nguyen, A K Batta, T S Chen, S Shefer – 1 August 1996 – The conversion of 7‐dehydrocholesterol to cholesterol is the last reaction in the cholesterol biosynthesis pathway catalyzed by the microsomal enzyme, 7‐dehydrocholesterol‐delta 7‐reductase. We studied whether malignant tumor growth that depends on cholesterol could be slowed by inhibiting late cholesterol biosynthesis.
