pubmed:abstractText |
The adenovirus EIa gene products activate transcription from the viral EIII and EIIaE promoters. We studied the mechanism of this stimulation by constructing a series of chimeric promoter recombinants containing the upstream regions of the EIII and EIIaE promoters linked to the TATA box-start-site regions of the viral major late and EIIa late promoters. By introducing these recombinants into HeLa cells together with recombinants producing the EIa gene products, we demonstrated that the induction of EIII and EIIaE transcription by EIa 13S and 12S mRNA products is dependent on sequences located in the upstream region (approximately -40 to -250) of these promoters. In addition, we showed that the major late and EIIa late upstream promoter regions do not contain such EIa-responsive sequence elements. In contrast, after transfection of these chimeric promoter recombinants into 293 cells (which constitutively express the EIa proteins), we found that their relative levels of transcription are similar and markedly different from those observed when they are cotransfected into HeLa cells with EIa protein-producing recombinants. We conclude that the efficiency of transcription from a given promoter in 293 cells is not necessarily related to the presence of a specific EIa-responsive element.
