    Oligonucleotide delivery. Efficient delivery of ONs such as small interfering RNAs (siRNAs), decoy-ONs and plasmids, and their analogues such as peptide nucleic acids (PNAs), locked nucleic acids (LNAs) and phosphorodiamidate morpholino oligomers (PMOs), are desired for controlling gene expression or for silencing the activity of certain proteins.Author: Maarja Mäe, Ülo Langel

    Splice-correction assay. HeLa pLuc705 cells (5 × 10 4) were seeded 24 h prior to experiments into 24-well plates.PS-2′-OMe SCOs were mixed with PF14 at different molar ratios (MRs) in MQ-water in 10% of the final treatment volume (i.e. 50 μl).Complexes were formed for 1 h at room temperature and meanwhile the cell medium was replaced in the wells with fresh serum-free or serum-containing ...Author: Kariem Ezzat, Samir El Andaloussi, Eman M.

    Jun 16, 2008 · The potential use of antisense and siRNA oligonucleotides as therapeutic agents has elicited a great deal of interest. However, a major issue for oligonucleotide-based therapeutics involves effective intracellular delivery of the active molecules.Author: Rudy Juliano, Md. Rowshon Alam, Vidula Dixit, Hyumin Kang

    Oct 01, 2005 · Dendrimer–oligonucleotide complexes were moderately effective for delivery of antisense and only poorly effective for delivery of siRNA. Conjugation of the dendrimer with the Tat cell penetrating peptide failed to further enhance the effectiveness of the dendrimer.Author: Hyunmin Kang, Robert DeLong, Michael H. Fisher, Rudolph L. Juliano

    Jun 16, 2008 · Ultimately, the oligonucleotide must exit from the endosome to reach its site of action in the cytosol or nucleus. Thus, in order to understand key issues in the intracellular delivery of oligonucleotides it is important to consider the multiple routes of endocytosis and the complex trafficking pathways that exist in cells.Author: Rudy Juliano, Md. Rowshon Alam, Vidula Dixit, Hyumin Kang

    second major obstacle in oligonucleotide delivery is the poor cell penetration capability of oligonucleotide-based drugs, which stems from their heavily negative charges.6 The negative charges of the oligonucleotide and the cell membrane act to repel the drug from the membrane, which complicates the mechanism of cellular internalization.

    The greatest success is likely to come for targeting organs that are most refractory to systemic naked oligonucleotide delivery such as the central nervous system, heart, and skeletal muscle where the need for effective delivery is paramount to realize the power of specific gene and disease mutation targeting that oligonucleotides offer.Author: Graham McClorey, Subhashis Banerjee
