| Research Abstract |
Here we developed a new class of exceptionally potent antisense oligonucleotides (ASOs) that are hybridized with complementary RNA (cRNA) strand and peptide-conjugated PNA strand. At first, we optimized the chemical modifications and length of the strands of the triple-stranded ASO (tsASO). Secondly, peptide-conjugated tsASO reduced mouse TRPV1 gene in dorsal root ganglia (DRG). Finally, we showed the delivery of DRG-delivered peptide-conjugated tsASO using confocal imaging and quantitative RT-PCR by systemic administration.
