Transcriptional regulation of the human transferrin gene by GADD153 in hepatoma cells

Kyung‐Ran You, Ming‐Jie Liu, Xue‐Ji Han, Zee‐Won Lee, Dae‐Ghon Kim – 30 December 2003 – The transcription factor CHOP/GADD153 is reportedly induced by cellular stresses such as UV light, genotoxic agents, and protein misfolding in the endoplasmic reticulum. However, the mechanism whereby induction of the GADD153 gene is linked to a downstream pathway is still unclear.

PPARγ ligands inhibit cholangiocarcinoma cell growth through p53‐dependent GADD45 and p21WAF1/Cip1 pathway

Chang Han, A. Jake Demetris, George K. Michalopoulos, Qimin Zhan, James H. Shelhamer, Tong Wu – 30 December 2003 – Ligands of peroxisome proliferator‐activated receptor‐γ (PPARγ) induce differentiation and growth inhibition in several human cancers. However, the role of PPARγ ligands in the growth control of human cholangiocarcinoma cells remains unknown. This study was designed to investigate the biological functions and molecular mechanisms of PPARγ ligands in the growth regulation of human cholangiocarcinoma cells.

A highly efficient, stable, and rapid approach for ex vivo human liver gene therapy via a FLAP lentiviral vector

Carlo Giannini, Serban Morosan, J. Guilherme Tralhao, Jacques Emmanuel Guidotti, Serena Battaglia, Karine Mollier, Laurent Hannoun, Dina Kremsdorf, Helene Gilgenkrantz, Pierre Charneau – 30 December 2003 – Allogenic hepatocyte transplantation or autologous transplantation of genetically modified hepatocytes has been used successfully to correct congenital or acquired liver diseases and can be considered as an alternative to orthotopic liver transplantation.

Insulin receptor substrate‐4 signaling in quiescent rat hepatocytes and in regenerating rat liver

Oscar Escribano, María Dolores Fernández‐Moreno, José Antonio Zueco, Cesar Menor, Jesus Fueyo, Rosa María Ropero, Inés Diaz‐Laviada, Irene D. Román, Luis G. Guijarro – 30 December 2003 – This study was designed to characterize insulin receptor substrate‐4 (IRS‐4) in isolated rat hepatocytes and to examine its role in liver regeneration. Subcellular fractionation revealed that 85% of IRS‐4 is located at isolated hepatocyte plasma membranes. The distribution of IRS‐4 among intracellular compartments remained unchanged in insulin‐stimulated cells.

All liver recipients benefit from the protocol 10‐year liver biopsies

Mylène Sebagh, Kinan Rifai, Cyrille Féray, Funda Yilmaz, Bruno Falissard, Bruno Roche, Henri Bismuth, Didier Samuel, Michel Reynès – 30 December 2003 – The value of late protocol biopsies after liver transplantation remains to be evaluated to highlight the therapeutic policies. The study population was composed of patients who survived with the initial graft and with an available 10‐year protocol biopsy (n = 143).
