RESUMO
We determined that the defect in beta interferon induction in Vero cells is due to the absence of the simian beta interferon (IFN-beta) gene. Nevertheless, the human IFN-beta gene or a hybrid gene, in which the human IFN-beta promoter-regulatory region directs expression of the chloramphenicol acetyltransferase gene (pIFN-CAT), could be induced in transfected Vero cells, and these cells also regulated IFN-beta mRNA (but not pIFN-CAT mRNA) posttranscriptionally. These results indicate that the instability in the human IFN-beta gene is coded for by the coding or 3'-end region of IFN-beta mRNA and that the human IFN-beta gene is regulated in Vero and human cells in an identical manner.
