Abstract:
Peptide nucleic acids (PNA) are promising antisense molecule for blocking gene expression in cell culture or in vivo. Nevertheless because they are poor efficient to pass the cellular membrane, it is necessary to use a vectorisation agent to observe an inhibitory effect. We describe the coupling of the rhodamine labeled 17-mer antisense PNA to a fusogenic peptide from antenapedia via S-S linkage, the studies of the penetration of this complex into fibroblast cells and its inhibitory effect on pim1 targeted protononcogene.
