Primary cultured hepatocytes are widely used in the Studies or basic and clinical hepatology. Finding an efficient method for gene transfer into primary licpatocytes will be ail important advance for these studies. In the present study, we evaluated the activity of an adenovirus vector including promoters for the Rous sarcoma virus (RSV), elongation factor 1 alpha, and cytomegalovirus (CMV) as well Lis the P-actin promoter/CMV enhancer (CA) using beta-galactosidase Lis a reporter gene. Although RSV and elongation factor lot promoters had low transcriptional activity in hepatocytes, the CA and CMV promoters had high activity. The CA promoter was the most active, mediating 50.3- and 204.4-fold more activity than the RSV promoter in mouse and rat hepatocytes, respectively. Dose-response studies revealed that transgene activity can be controlled by as much as 1000-fold, by selection of the promoter and the number of infectious particles per cell. These findings should help in the construction of adenovirus vectors for expressing genes of interest in rodent primary Cultured hepatocytes. (c) 2008 Elsevier B.V. All rights reserved.
