How to get transformed E. coli strains using Promega´s pGL3...

I respectively cloned two different promoters from human genes on Promega´s pGL3 vector but I can't obtain any E. coli transformants. The transformation with pGL3 basic control vector works pretty well in all E. coli tested strains: .JM109 (recommended by Promega); Top10 and DH5alfa. It seems the E. coli strains just do not accept the plasmid containing human promoters.Transformation methods tested: electroporation and also Calcium chloride competent cells for all strains.Any suggestion?
