Expressions of basic fibroblast growth factor and its receptors and their relationship to proliferation of human hepatocellular carcinoma cell lines

S Ogasawara, H Yano, A Iemura, T Hisaka, M Kojiro – 1 July 1996 – On six human hepatocellular carcinoma (HCC) cell lines (KIM‐1, KYN‐1, KYN‐2, KYN‐3, HAK‐1A, and HAK‐1B), we examined expressions and functions of the proteins and messenger RNAs (mRNAs) of basic fibroblast growth factor (bFGF) and its receptor, i.e., fibroblast growth factor receptor‐1 (FGFR‐1), as well as mRNA expressions of FGFR‐2 approximately 4. All six cell lines expressed the proteins and mRNAs of bFGF and FGFR‐1, and at least one of FGFR‐2 approximately 4 mRNAs.

High insulin‐like growth factor binding protein 1 levels in cirrhosis: Link with insulin resistance

E Shmueli, J P Miell, M Stewart, K G Alberti, C O Record – 1 July 1996 – Hyperinsulinemic euglycemic clamps were performed on six patients with compensated alcoholic cirrhosis and on six normal comparison subjects. As in previous studies, glucose uptake in the cirrhotic patients was only 21% of the comparison value. The cirrhotic patients had high growth hormone (GH) and low insulin‐like growth factor‐I (IGF‐I) levels, with low insulin‐like growth factor‐binding protein (IGFBP)‐3 levels, but surprisingly high IGFBP‐I levels (26.8 ± 8.4 microgH vs. 3.2 ± 0.2 microm/L, P < .001).

The metabolic organization of the adult human liver: A comparative study of normal, fibrotic, and cirrhotic liver tissue

L Racine‐Samson, J Scoazec, A D'Errico, M Fiorentino, L Christa, A Moreau, C Roda, W F Grigioni, G Feldmann – 1 July 1996 – Little is known about the alterations of metabolic organization of the human liver tissue in chronic liver diseases.

Immunoregulatory cytokines in chronic hepatitis C virus infection: Pre‐ and posttreatment with interferon alfa

T V Cacciarelli, O M Martinez, R G Gish, J C Villanueva, S M Krams – 1 July 1996 – T lymphocytes and immunoregulatory cytokines may be important in the host response to hepatitis C virus (HCV) infection. T‐helper type 1 (Th1) cytokines (interleukin [IL]‐2, interferon gamma [IFN‐gamma]) are required for host antiviral immune responses, including cytotoxic T‐cell generation and natural killer cell activation, while T‐helper type 2 (Th2) cytokines (IL‐4,IL‐10) can inhibit the development of these effector mechanisms.

Morbidity in patients with posttransplant diabetes mellitus following orthotopic liver transplantation

Kynan C. Trail, Timothy M. McCashland, Jennifer L. Larsen, Thomas G. Heffron, Robert J. Stratta, Alan N. Langnas, Ira J. Fox, Rowen K. Zetterman, Jeremiah P. Donovan, Michael F. Sorrell, Todd J. Pillen, Elizabeth I. Ruby, Byers W. Shaw – 1 July 1996 – It is not well understood whether posttransplant diabetes mellitus (PTDM) following orthotopic liver transplantation (OLTx) alters postoperative morbidity. This study was designed to evaluate this question.

Tissue inhibitor of metalloproteinase‐1 messenger RNA expression is enhanced relative to interstitial collagenase messenger RNA in experimental liver injury and fibrosis

J P Iredale, R C Benyon, M J Arthur, W F Ferris, R Alcolado, P J Winwood, N Clark, G Murphy – 1 July 1996 – Liver fibrosis results from a relative imbalance between synthesis and degradation of matrix proteins. We have previously described release of the protein collagenase inhibitor, tissue inhibitor of metalloproteinase‐1 (TIMP‐1), by culture‐activated human hepatic stellate cells (HSCs). In this study, we have investigated the relative expression of TIMP‐1 and interstitial collagenase in culture‐activated rat HSCs and rat models of liver injury and fibrosis.

S‐adenosyl‐L‐methionine prevents disruption of canalicular function and pericanalicular cytoskeleton integrity caused by cyclosporin A in isolated rat hepatocyte couplets

I D Roman, G D Johnson, R Coleman – 1 July 1996 – Isolated rat hepatocyte couplets were used to study the effect of S‐adenosyl‐L methionine (SAMe) treatment on disruption of canalicular function caused by cyclosporin A (CyA). Canalicular function was assessed by counting the percentage of couplets that were able to accumulate the fluorescent cholephile choly‐lysyl‐fluorescein (CLF) into the canalicular vacuole between the two cells, i.e., canalicular vacuole accumulation (CVA).

Systemic hemodynamics and serum nitrate levels in patients undergoing endoscopic variceal ligation

M Yokoyama, H Shijo, K Ota, K Kubara, H Kokawa, T Kim, N Akiyoshi, M Okumura, K Inoue – 1 July 1996 – The effects of endoscopic variceal ligation (EVL) on systemic hemodynamics are unknown. This study was conducted to determine whether the obliteration of portal‐systemic collaterals by EVL affects systemic hemodynamics and serum nitrate concentrations in patients with compensated cirrhosis. We measured systemic and hepatic hemodynamics, azygos vein blood flow (AzBF), and serum nitrate concentrations before and immediately following EVL.
