Sequence specific recognition and functional inhibition of biomedically relevant double-helical RNAs is highly desirable, but remains a formidable problem. The present study demonstrates that electroporation of a triplex-forming peptide nucleic acid (PNA), modified with 2-aminopyridine (M) nucleobases, inhibited maturation of endogenous microRNA-197 in SH-SY5Y cells, while having little effect on maturation of microRNA-155 or −27a. In vitro RNA binding and Dicer inhibition assays suggested that the observed biological activity was most likely due to a sequence-specific PNA-RNA triplex formation that inhibited the activity of endonucleases responsible for microRNA maturation. The present study is the first example of modulation of activity of endogenous non-coding RNA using M-modified triplex-forming PNA.
