Fig. (6) The HHV-8 promoter is transactivated by Ad5 E1A and the E1A deletion mutant delCR2. E1A derivatives lacking an intact aminoterminus were not able to transactivate the LANAp. The transfection procedure was as described in Fig. (4). Data represent three independent experiments with transfection efficiency being 50 ± 15%. *p< 0.005.
