| abstract |
The present invention is concerned with modified polynucleotides derived from a native gene and having a reduced or increased number of epigenetic control motifs, at the nucleotide level, as compared to the native gene. These polynucleotides are useful to study, increase and/or reduce genes expression, and to improve DNA vaccination methods. The present invention also relates to methods of using these modified polynucleotides in in vitro and in vivo expression systems. |
