Abstract

A peptide nucleic acid (PNA) targeting a splice junction of the murine PTEN primary transcript was covalently conjugated to various basic peptides. When systemically administered to healthy mice, the conjugates displayed sequence-specific alteration of PTEN mRNA splicing as well as inhibition of full length PTEN protein expression. Correlating activity with drug concentration in various tissues indicated strong tissue-dependence, with highest levels of activity observed in adipose tissue. While the presence of a peptide carrier was found to be crucial for efficient delivery to tissue, little difference was observed between the various peptides evaluated. A second PNA-conjugate targeting the murine insulin receptor primary transcript showed a similar activity profile, suggesting that short basic peptides can generally be used to effectively deliver peptide nucleic acids to adipose tissue.
