Abstract

We have constructed 293 cell lines expressing the site-specific Cre recombinase from bacteriophage P1, that acts on a 34 bp target sequence called loxP. Stably transformed cells were obtained by transfection with a plasmid containing Cre and a selectable marker under the control of viral promoters. The resulting 293Cre cell lines could be used to induce expression from adenovirus vectors containing reporter genes under the control of a Cre responsive "molecular switch." High efficiency recombination was observed for Ad viral DNA containing loxP sites. The Cre expressing cell lines described here are likely to be useful for several purposes: For expression of toxic gene products from Cre inducible viral vectors, to induce recombination between loxP sites in transfected plasmids, and to induce deletions or rearrangements of genes defined by loxP sites in viral genomes.
