The avid hybridization of peptide nucleic acid (PNA) to DNA and RNA, coupled with the analogue's stability toward enzymatic degradation, has led to its investigation as an antigene/antisense agent. PNA targeted toward the 5'-UTR of an mRNA transcript can effect efficient silencing; however, if targeted to an area within the coding region, the PNA can be displaced by the moving ribosome and be an ineffective antisense agent. Platinum-appended and standard PNAs antisense to an area within the open-reading frame of the gene noggin, were injected into Xenopus laevis embryos. Phenotypic responses were observed and the preliminary results are reported herein.
