title: Reactivation of liver-specific gene expression in an immortalized human hepatocyte cell line by introduction of the human HNF4alpha2 gene.
abstract: An immortalized human hepatocyte cell line (OUMS-29) was established from fetal liver by transfection with the SV-40 large T antigen gene that has certain liver-specific functions such as albumin production and enzyme activities of CYP1A1, 1A2, and 2E1. To make OUMS-29 cells express other liver-specific functions, the human hepatocyte nuclear factor 4alpha2 (HNF4alpha2) gene was introduced into the cells, because this gene was found to be markedly down-regulated. The transduced HNF4alpha2 was overexpressed in the nuclei of the transfected cells, and its DNA-binding activity was also detected. The liver-specific genes such as apolipoprotein AI, CII, CIII, blood coagulation factor X, alpha1-antitrypsin, and HNF1alpha were up-regulated. Thus, this cell line is expected to be a useful tool for studying the differentiated human hepatocyte functions.
