Human adenovirus type 12 (Ad12) cannot replicate in hamster cells. There is a complete block of viral DNA replication and of the expression of late viral genes. Early viral functions are expressed. In contrast, hamster cells are permissive for human adenovirus type 2 (Ad2). Some of the Ad12-specific functions are insufficient to support viral replication in hamster cells, or else cellular functions are missing or inhibitory for Ad12 replication. It was shown that the block in the replication and late expression of the Ad12 genome in hamster cells could, at least in part, be complemented by Ad2 and adenovirus type 5 (Ad5) functions. When hamster cells were coinfected with Ad2 (or Ad5) and Ad12, both Ad2 (Ad5) and Ad12 DNA replicated. Ad2 (Ad5) virions were produced in double-infected hamster cells. The assembly of intact Ad12 virions was not detectable by the techniques used here. The analysis was further refined by Ad12 superinfecting Ad2- or Ad5-transformed cells which carried in an integrated form defined fragments of the Ad2 or Ad5 genome. Persistence and continued expression of the left terminus of the Ad2 or Ad5 DNA in these cells has been documented and helped to support replication and late expression of Ad12 DNA. It remains to be determined which of the E1 functions of Ad2 or Ad5 were responsible for the helper effect. Investigations on the biochemical mechanism of this complementation will entail studies on very complex viral and possibly cellular functions involved in the control of viral gene expression. |
