Nuclear scaffold‐associated protease: In situ nuclear localization and effects of a protease inhibitor on growth and morphology of a ras‐transformed hepatocyte cell line

Gary A. Clawson, Ling Ren, Harriet C. Isom – 1 October 1995 – We have previously identified a multicatalytic protease (MCP) activity associated with the nuclear scaffold (NS) in hepatocytes and fibroblasts. When we used the chloromethylketone protease inhibitor AAPFcmk, which is targeted to chymotrypsinlike protease activity, we observed a dramatic inhibition of transformation of fibroblasts, with effects that were relatively selective for the NS fraction.

Portal hypertension and iron depletion in patients with genetic hemochromatosis

Anna Ludovica Fracanzani, Silvia Fargion, Riccardo Romano, Dario Conte, Alberto Piperno, Roberta D'Alba, Clara Mandelli, Mirella Fraquelli, Stefania Pacchetti, Mario Braga, Gemino Fiorelli – 1 October 1995 – Clinically, portal hypertension has been considered to be less common and less severe in patients with cirrhosis resulting from iron overload in homozygotes for genetic hemochromatosis than in patients with cirrhosis of other causes.

Elevated mitochondrial gene expression during rat liver regeneration after portal vein ligation

Yasuhiro Shimizu, Hiroshi Suzuki, Yuji Nimura, Shigemi Onoue, Masato Nagino, Masashi Tanaka, Takayuki Ozawa – 1 October 1995 – We explored the molecular basis of mitochondrial energy production during rat liver regeneration after portal vein ligation. Ligation of the left branch of the portal vein induces an increase in the weight of the nonligated lobe, counterbalancing the reduced weight of the ligated lobe. Using this model, we investigated changes in mitochondrial DNA‐binding proteins, mitochondrial DNA, and mitochondrial messenger RNA (mRNA) in rat hepatocytes of the nonligated lobes.

Regulation of bile acid synthesis by deoxycholic acid in the rat: Different effects on cholesterol 7α‐hydroxylase and sterol 27‐hydroxylase

Sarah Shefer, Betsy T. Kren, Gerald Salen, Clifford J. Steer, Lien B. Nguyen, Thomas Chen, G. Stephen Tint, Ashok K. Batta – 1 October 1995 – We examined the effects of feeding deoxycholic acid (1% and 0.4% of diet), alone and in combination with ursodeoxycholic acid, on serum and biliary bile acid concentrations, hepatic morphology, and the activities and steady‐state messenger RNA (mRNA) levels of HMG‐CoA reductase and cholesterol 7α‐hydroxylase in the rat.

Intrahepatic mast cells in chronic liver diseases

Desmond J. Farrell, Julie E. Hines, Andrew F. Walls, Peter J. Kelly, Mark K. Bennett, Alastair D. Burt – 1 October 1995 – Mast cells are known to be present in human liver but their distribution and density in normal livers and in chronic liver diseases have not previously been examined. In this study, we quantified mast cell numbers and examined their distribution in percutaneous biopsy specimens from normal livers (n = 8) and in two chronic progressive liver diseases: primary biliary cirrhosis (PBC) (n = 40) and alcoholic liver disease (n = 33).

Characteristic difference of hepatocellular carcinoma between hepatitis B‐ and C‐ viral infection in Japan

Yasushi Shiratori, Shuichiro Shiina, Masatoshi Imamura, Naoya Kato, Fumihiko Kanai, Takahito Okudaira, Takuma Teratani, Gohichi Tohgo, Nobuo Toda, Makoto Ohashi, Keiji Ogura, Yasuro Niwa, Takao Kawabe, Masao Omata – 1 October 1995 – Characteristics of 205 consecutive patients with hepatocellular carcinoma (HCC) admitted during 1990 to 1993 have been analyzed from the standpoint of hepatitis viral infection in Japan.

Subcellular distribution of large and small hepatitis delta antigen in hepatocytes of hepatitis delta virus superinfected woodchucks

John M. Cullen, Caroline David, Jia‐Gang Wang, Paul Becherer, Stanley M. Lemon – 1 October 1995 – Hepatitis delta virus (HDV) encodes only a single protein, the hepatitis delta antigen (HDAg), which is expressed as two molecular forms (large and small) with different functions in viral replication. Compared with small antigen, large antigen has a 19 residue carboxyl terminal extension.
