Peptide Nucleic Acids and Gene Editing: Perspectives on Structure and Repair

open access: yesMolecules, 2020
Unusual nucleic acid structures are salient triggers of endogenous repair and can occur in sequence-specific contexts. Peptide nucleic acids (PNAs) rely on these principles to achieve non-enzymatic gene editing.

Extracellular vesicles mediated exocytosis of antisense peptide nucleic acids [PDF]

open access: yesMolecular Therapy: Nucleic Acids, 2021
Peptide nucleic acids (PNAs), a synthetic DNA mimic, have been extensively utilized for antisense- and antigene-based biomedical applications. Significant efforts have been made to increase the cellular uptake of PNAs, but here we examined relatively ...

Therapeutic and diagnostic applications of antisense peptide nucleic acids [PDF]

open access: yesMolecular Therapy: Nucleic Acids
Peptide nucleic acids (PNAs) are synthetic nucleic acid analogs with a neutral N-(2-aminoethyl) glycine backbone. PNAs possess unique physicochemical characteristics such as increased resistance to enzymatic degradation, ionic strength and stability over

Cyanobacteria produce N-(2-aminoethyl)glycine, a backbone for peptide nucleic acids which may have been the first genetic molecules for life on Earth. [PDF]

open access: yesPLoS ONE, 2012
Prior to the evolution of DNA-based organisms on earth over 3.5 billion years ago it is hypothesized that RNA was the primary genetic molecule. Before RNA-based organisms arose, peptide nucleic acids may have been used to transmit genetic information by ...

Peptide Nucleic Acid Microarrays [PDF]

open access: green, 2004
A fast and economical procedure for the production of peptide nucleic acid (PNA) microarrays is presented. PNA oligomers are synthesized in a fully automatic manner in 96-well plates using standard Fmoc chemistry. Subsequently, the oligomers are released from the support and spotted onto glass or silicone slides, which were activated by succinimidyl ...
