RESUMO
Infection of the continuous simian cell lines CV-1 and BSC-1 with human adenovirus type 2 (Ad2) is abortive. However, the restriction of Ad2 reproduction in these cells can be overcome by increasing the Ad2 infectious dose or by coinfection with simian virus 40. Vero, another established simian cell line free of detectable endogenous simian virus 40 DNA, is not restricted in its ability to promote Ad2 growth even at low input multiplicities of Ad2 and in the absence of SV40 helper. The amount of structural Ad2 proteins in total cell extracts of enhanced BSC-1 cells is at least two orders of magnitude higher than that of unenhanced cells. In contrast, comparable quantities of Ad2 mRNA specifying these proteins are found in both the enhanced and the unenhanced cell. Both sets of mRNA can be translated in a cell-free system with equal efficiency.
