Abstract
Purpose. The goal of this study was to evaluate the ability of nanoparticles to be used as a targeted delivery system for oligonucleotides.
Methods. Pharmacokinetic and tissue distribution were carried out in mice by measuring the radioactivity associated to the model oligothymidylate 33P-pdT16 loaded to poly(isobutylcyanoacryrate) (PIBCA) nanoparticles. In addition, we have used a TLC linear analyzer to measure quantitatively on a polyacrylamide gel electrophoresis, the amount of non degraded pdT16
Results. Organ distribution study has shown that nanoparticles deliver 33P-pdT16 specifically to the liver reducing its distribution in the kidney and in the bone marrow. Nanoparticles could partially protect pdT16 against degradation in the plasma and in the liver 5 min after administration, whereas free oligonucleotide was totally degraded at the same time.
Conclusions. Nanoparticles protect oligonucleotides in vivo against degradation and deliver them to the liver.
