Abstract:
Peptide nucleic acids (PNAs) are artificial nucleic acids with a peptide backbone instead of sugar phosphate backbone of DNA or RNA. Their resistance to degradation, selectivity and greater binding affinity in comparison to usual nucleic acids led to consideration of their great potential for different applications. For example, they can be used in molecular diagnostics and antisense therapeutics such as antimicrobial agents or gene regulatory tools. On the other hand, large hydrophilic property of PNA molecules, which inhibit them to cross cell membranes readily, is an obstacle for their delivery to considered target cells and a limiting criterion for their applications. Therefore, PNA delivery technologies have been developing to hurdle this limitation. For example, addition of lysine residues, charged membrane penetrating peptide sequences, PNAs conjugated with antibodies or steroids, cationic liposomes as carriers of PNA conjugates, protective peptides and technology of photochemical internalization (PCI) as well as by the recent technology of nanoparticle-based delivery have been employed. In this article we compared different delivery technologies which can be applicable to PNAs. As a result nanoparticle-based delivery showed more advantages in comparison to others and its application is growing fast.
