| biochemical consequences of type 2 adenovirus and simian virus 40 double infections of african green monkey kidney cells. | african green monkey kidney (agmk) cells were nonpermissive hosts for type 2 adenovirus although the restriction was not complete; when only 3 plaque-forming units/cell was employed as the inoculum, the viral yield was about 0.1% of the maximum virus produced when simian virus 40 (sv40) enhanced adenovirus multiplication. the viral yield of cells infected only with type 2 adenovirus increased as the multiplicity of infection was increased. type 2 adenovirus could infect almost all agmk cells in ... | 1970 | 4315958 |
| adenovirus transformation of hamster embryo cells. | inoculation of hamster embryo cell cultures with human adenovirus type 12 (ad12) or simian adenovirus (sa7) resulted in the formation of foci of morphologically transformed cells within 12 days. the rapid appearance of well-defined foci was dependent upon the transfer of cells into new plates, with sufficient dilution after virus adsorption, and was independent of virus dose. dose-response studies showed linearity of focus formation with dilution of ad12 or sa7. results averaged from several exp ... | 1968 | 4316017 |
| transformation of african green monkey kidney cells by irradiated adenovirus 7-simian virus 40 hybrid. | the ability of adenovirus 7-simian virus 40 (sv40) hybrid (strain ll "e-46") to replicate decreased exponentially as a function of the amount of gamma-irradiation; the ability to induce sv40 and adenovirus 7 t antigen decreased at a much slower rate. nevertheless, the virus was still able to transform african green monkey kidney cells at a radiation dosage that had completely destroyed its replication ability. all transformed colonies were positive for sv40 t antigen but were negative for adenov ... | 1968 | 4316019 |

| characterization of the strain of adenovirus type 7 carrying the defective monkey cell-adapting component. | the strain of adenovirus type 7 carrying the defective monkey cell-adapting component (mac) has been further characterized. mac is more sensitive to inactivation by ultraviolet light than the associated adenovirus, which, in turn, is more rapidly inactivated than complete simian virus 40 (sv40). the 37% dose was 16 sec for mac, 60 sec for adenovirus, and 84 sec for sv40. filtration through membranes revealed that both mac and adenovirus were retained by 100-mmu filters. mac equilibrated in cesiu ... | 1967 | 4316236 |
| thymidine kinase from normal, simian virus 40-transformed and simian virus 40-lytically infected cells. | simian virus 40 (sv40) infection of human diploid cells failed to cause an enhanced production of thymidine kinase during the first 10 days after infection. thymidine kinase activities from extracts of sv40-transformed cultures (human or simian) were considerably higher than the activity levels in extracts from the normal cells of origin. in addition, whereas the kinase activities obtained for human diploid cultures decreased as the cell sheet became confluent, the kinase activities for sv40-tra ... | 1967 | 4316240 |
