Research Abstract

We introduced human connective tissue growth factor (CTGF) cDNA into the E1 region of cosmid vectors in order to create recombinant adenovirus CTGF (adeno-CTGF). Control adenovirus vectors into which adeno-CTGF and Escherichia coli beta-galactosidase genes were introduced were intravenously injected into 7-week-old male Wister rats, and their hepatic tissues were harvested 3 and 7 days later. CTGF was expressed in the liver 3 days after the administration, but its expression was not observed 7 days after the administration. A comprehensive analysis of gene expression by GeneChip using hepatic tissue showed that gene expression in fibrosis had been increased both 3 and 7 days later.
