Peptide nucleic acids: on the road to new gene therapeutic drugs

Pharmacology & Toxicology
Peter E Nielsen


Peptide nucleic acid (PNA) is a DNA mimic based on a pseudopeptide (polyamide) backbone. PNA oligomers bind strongly and with high sequence specificity to complementary targets in RNA (or DNA), and they show very high biological stability. Furthermore, studies in cell free systems have demonstrated potent antisense (inhibition of translation) and antigene (inhibition of transcription) activity of PNA. Recently, several studies reporting methods for cellular delivery of PNA as well as antisense effects of PNA in cells ex vivo and in rats have appeared. The potential of developing PNA derived gene therapeutic drugs is discussed.

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
